  • gridview databind

    - by frenchie
    Hi, I'm doing a gridview with an object datasource: List<MyObject> TheSource = a linq query At some point, I have MyGridview.DataSource = TheSource; MyGridview.Databind(); and an OnRowDataBound event handler that's tied to the databinding. In that event handler, how do you make column 2 contain 2 objects from TheSource. For instance, in the TheSource, there is a variable for FirstName and another one for LastName. Column 2 needs to contain both the first and last name in the same cell. Thanks.

  • Excel file reading with 2007 office connection string.

    - by p-vasuu
    Actually in my system having 2007 office then i am reading the 2003 .xls file with using the 2007 connection string string ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Filename + ";Extended Properties=\"Excel 8.0;HDR=YES;\""; data is not reading. But if the first row first column data length is lessthen 255 then the following first columns data is cutting up to 255 character. If the First row first column is morethan the 255 character then the following first columns data is reading fine. Is there any back word computability is there?

  • Can't create a MySQL query that generates 4 rows for each row in the table it references.

    - by UkraineTrain
    I need to create a MySQL query that generates 4 rows for each row in the table it references. I need some of the information in those rows to repeat and some to be different. In the table each row stands for one day. I need to break the day up in 6 hour increments, hence the four rows for each entry. I need to create one column which for each day will have '12AM', '6AM', '12PM', and '6PM' values and another column will have the corresponding numeric values calculated for those entries. Thanks a lot in advance and I will really appreciate any help on this.

  • Can layouts be chosen by Grails controllers?

    - by maerics
    I'm building a CMS as a learning exercise in Grails and would like to give content managers the ability to choose between different HTML page structures (e.g. 2 column, 3 column, etc). Grails Layouts seem like a logical choice but is it possible for a Grails controller to explicitly name which layout will be used for rendering? Ideally there would be a layout option to the render method, per Ruby on Rails but I don't see anything like it. It seems like it might be possible using the applyLayout method by passing the name of the layout but this requires each GSP page to explicitly request layout (annoying overhead per-page) rather than using Layout by Convention. Any ideas?

  • Excel PivotTable : Calculated Field / Item for Period Comparison

    - by dino76
    HI All, If I have a PivotTable in Excel 2007 with a date field. I understand that I can group the date by day, month or even year using Group Field (Years & Months). If I combine with product perspective, the PivotTable may look like this Sum of Sales_Total | Column Labels Row Labels | PRODUCT-001 | PRODUCT-002 | Grand Total - 2006 | 2000 | 1500 | 3500 Jan | 1700 | 800 | 2500 Feb | 300 | 700 | 1000 - 2007 | 1000 | 1500 | 2500 Jan | 700 | 800 | 1500 Feb | 300 | 700 | 1000 - 2008 | 600 | 700 | 1300 Jan | 600 | 700 | 1300 Now, what I want to do is to compare Jan 2008 - Jan 2006 and Jan 2007 - Jan 2006. Something like this : | Column Labels | PRODUCT-001 | | ... Row Labels | Sum of Sales | Sum of Last Sales | - 2006 | 2000 | | Jan | 1700 | | Feb | 300 | | - 2007 | 1000 | 2000 | Jan | 700 | 1700 | Feb | 300 | 300 | - 2008 | 600 | 1000 | Jan | 600 | 700 | Is it possible ? If so, how to do that ? Thanks, D. Chopins

  • mysql update too slow when joining multiple tables

    - by user293487
    Hi, I have two tables. they looks like as follows: Id (int) Tags char(128). the column Tags in table A does not have value. It is empty. The column Tags in table B has value. What I want to copy the Tags in table B to corresponding place of table A. the mapping is based on Id. My sql query is: update A INNER JOIN B set A.Tags = B.Tags where A.Id = B.Id There are about 2,000,000 rows in table A, and 50,000 rows in table B. The update seems very slow.... Could anyone tell me how to make it run faster?

  • find lowest neighbor matlab

    - by user1812719
    I am trying to write a function [offset,coffset]=findLowNhbr(map) that for each pixel in a map finds the eight neighbors to the pixel, and returns two matrices with both the row and column offsets to the lowest neighbor (uses the numbers -1, 0 and 1). Border pixels are given 0 offsets for both the row and column, since they do not have neighbors. Here is what I think the general plan for this function should be: For each point, find the eight nearest neighbors. If the neighbor is lower than the point, return -1 If the neighbor is at the same elevation as the point, return 0 If the neighbor is higher than the point, return +1 Store these offsets in two matrices. I am at a complete loss as to where to start, so any advice or questions are welcome!

  • making a combined sum of two columns

    - by bsandrabr
    I have a table (apples) containing: cid date_am date_pm ---------------------- 1 1 1 2 2 1 3 1 3 1 1 2 I asked a question earlier (badly) about how I would rank the customers in order of the number of ones(1) they had. The solution was (based on one column): SELECT cid, sum( date_pm ) AS No_of_ones FROM apples WHERE date_am =1 GROUP BY cid ORDER BY no_of_ones DESC This works great for one column but how would I do the same for the sum of the two columns. ie. SELECT cid, sum( date_pm ) AS No_of_ones FROM apples WHERE date_am =1 add to SELECT cid, sum( date_am ) AS No_of_ones FROM apples WHERE date_pm =1 GROUP by cid ORDER by no_of_ones(added) hope I've managed to make that clear enough for you to help -thanks

  • I have to do two seemingly mutually exclusive things on leaving an asp:textbox. Please help me get

    - by aape
    This project has gone from being a simple '99 Ford F-150 to the Homer. I've got controls with a gridview with textboxes for data entry. All the user controls on the pages are in AJAX updatepanels. User types in a database column or budget entity or some other financial thing they want to include in the report. The textboxes in the gridview have autopostback = true set. overly long background info When the user leaves the textbox, during the postback (triggered by onTextChanged) I do some validation back on the server on their entry - regexs, do they have rights to that column, is that column locked, etc. If it fails, I put a error message next to the textbox. If it passes, I wipe out any title or error that used to be next to the code. Focus is getting lost from the postback if they're tabbing out of the box, rather than going to the next textbox in the gridview. So to fix that I need, if their leaving the tb via the tab key, to also figure out what textbox or gridviewrow they're on, if they're not on the last row, and after the validation and labeling, put the focus on the textbox in the next row. I can't figure out how, in ontextchanged, to find what caused me to leave the textbox, so I'm thinking use javascript onkeyup to test the key pressed and then find the next box etc, but the ontextchanged fires first and then the js never does, and also, since the control is all AJAXed, the javascript can't find the textboxes because when you enter the page everything is collapsed (the requirements people loooove to collapse and expand things), and so when it's expanded, all the 'new' textboxes are up in the viewstate stuff in the page source, and not down where javascript can see them. The questions So I'm wondering if I can have an onblur in the javascript that can trigger a postback where I can do my validation and such, and either 1) include the keypressed or pick it out of sender in the event or 2) followup the onblur with onkeyup and somehow figure out what textbox is next on the grid and throw focus there. Or, is there another .NET based approach that could work for this? In terms of tearing the whole thing down and starting from scratch, I couldn't sell that to the bosses, I'm past the point of no return as far as that goes.

  • Use TinyInt to hide/show controls?

    - by grady
    Hi, I have 6 buttons on my GUI. The visibility of the buttons can be configured via checkboxes. Checking the checkbox and saving means the correpsonding button should be shown. I am wondering if it is somehow possible to have one TinyInt column in the database which represents the visibility of all 6 buttons. I created an enum for the buttons, it looks like that: public enum MyButtons { Button1 = 1, Button2 = 2, Button3 = 3, Button4 = 4, Button5 = 5, Button6 = 6 } Now I am wondering how to say that for example only button1, button5 and button6 are checked using this one column. Possible at all? Thanks :-)

  • ActiveRecord :through to set default values on through table.

    - by Dmitriy Likhten
    I would like to set a default value in a has_many through association. Lets say I have three models: People Friends Dogs A person can request that a dog becomes their friend. So a person would create an association where friends has an active column = false. User has_many :friends has_many :dogs, :through => :friends Now when I assign a dog to a user User.find(1).dogs << dog The friends table has null in the active column. My friends model is defined as Friend def initialize(args = {}) super(args) active = false end yet this does not work because the friend object is never created. Do I have to manually create one?

  • Help with Custom Workflow that checks db

I've done some really simple "hello world" type of apps with windows workflow foundation 3.5 but have not yet grasped how to do go about implementing something like this. Any help with code or articles on this would be extremely useful. Thanks in advance.

  • Load only some columns with Hibernate native SQL queries

    I have a table on the database and I want to load only some columns from the result set.

I found also a bug in Hibernate JIRA (http://opensource.atlassian.com/projects/hibernate/browse/HHH-3035). Anyone knows how to accomplish this task with a workaround?

  • JQGrid: Dynamically set a cell to uneditable based on content

    - by Shawn
    I'm having some issues getting some cells (with cellEdit: true) to be non-editable even though the column is set to editable. I've tried many ways, like beforeEditCell, formatters, etc. None seem to work. The closest I've got is by setting a formatter to the column that I'd like to be editable and then using setCell to set the 'not-editable-cell' class (snippet below). The first time you click the cell, it unfortunately goes into edit mode, but if you click elsewhere and try to re-edit the cell, it's successfully uneditable. I've also tried using the same snipped but inside of beforeEditCell, it successfully stops the cell from being edited but in turn 'freezes' the grid. You can no longer select any other cell. function noEditFormatter(cellValue, options, rowObject) { if (cellValue == 'test') jQuery("#grid").jqGrid('setCell', options.rowId, 'ColName', '', 'not-editable-cell'); return cellValue; } Any help would be much appreciated.

  • group_concat on an empty join in MySQL

    - by Yossarian
    Hello, I've got the following problem: I have two tables: (simplified) +--------+ +-----------+ | User | | Role | +--------+ +-----------+ | ID<PK> | | ID <PK> | +--------+ | Name | +-----------+ and M:N relationship between them +-------------+ | User_Role | +-------------+ | User<FK> | | Role<FK> | +-------------+ I need to create a view, which selects me: User, and in one column, all of his Roles (this is done by group_concat). I've tried following: SELECT u.*, group_concat(r.Name separator ',') as Roles FROM User u LEFT JOIN User_Role ur ON ur.User=u.ID LEFT JOIN Role r ON ur.Role=r.ID GROUP BY u.ID; However, this works for an user with some defined roles. Users without role aren't returned. How can I modify the statement, to return me User with empty string in Roles column when User doesn't have any Role? Explanation: I'm passing the SQL data directly to a grid, which then formats itself, and it is easier for me to create slow and complicated view, than to format it in my code. I'm using MySQL

    I have a table with 300 million rows in Microsoft SQL Server 2008 R2. There is a clustered index on the date column [DataDate] which means that the entire table is ordered by the date column. How do I stream out the data from this table, into my .NET application, in 10000 row chunks? Environment: Using C#. Have to be able to pause the data stream at any point, to allow the client to process the rows. Unfortunately, cannot use a select * from as this will select the entire table (its 50GB - it won't fit into memory).

  • Significance of date 02/31/2157?

    - by dpatchery
    I work in a large scale IT support environment. Twice now we have seen an invalid date of 02/31/2157 being inserted in an Oracle DATE column. So far I have not been able to reproduce this problem, but it appears to be happening occasionally when a user attempts to save '00/00/0000' into the column. I believe the value is originating from a PowerBuilder DataWindow update. The application uses myriad libraries for all sorts of technologies, so this question may be a bit vague, but... Has anyone seen the date 02/31/2157 in some established library that Oracle could be defaulting to when some other invalid date is entered? Perhaps an end-of-time concept analogous to the beginning-of-time date of 1/1/1970?

  • Is there a way to include commas in CSV columns without breaking the formatting?

    - by editor
    I've got a two column CSV with a name and a number. Some people's name use commas, for example "Joe Blow, CFA." This comma breaks the CSV format, since it's interpreted as a new column. I've read up and the most common prescription seems to be replacing that character, or replacing the delimiter, with a new value (e.g. "this|that|the, other"). I'd really like to keep the comma separator (I know excel supports other delimiters but other interpreters may not). I'd also like to keep the comma in the name, as "Joe Blow| CFA" looks pretty silly. Is there a way to include commas in CSV columns without breaking the formatting, for example by escaping them?

  • converting tabular structures in a Word document into an actual table or reading data from the tabul

    - by Chris
    I have a macro which can read the last cell/column of all tables in a Word 2003/2007 document and store the data in an MS-Access table. But, some Word documents have the data in structures like a table format but are not actually tables. The structure looks like a table, but the table borders are actually line connectors. These documents were created by a software(VeryPDF PDF to Word converter) which converted the PDF documents(the original format these documents were) into Word documents. Is there a way I can convert/replace the tabular structures with actual tables in Word so that I can use the macro? Or, is there a way I can read the value of the last column from the tabular structures using some VBA code? Any advice would be appreciated.
