  • Question about inserting/updating rows with MS SQL (ASP.NET MVC)

    - by Alex
    I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today But what if the row doesn't exist? I'd have to use INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today) How can I check if the row exists or not? Is there any way different from doing the COUNT(*)? If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.

  • asp.net-mvc: javascript caching

    - by Omu
    I'm thinking whether it makes sense in order to increase the speed of the website to do some strategy of caching the js files that are being included ? one idea that I have is to do something like this: [OutputCache(Location = OutputCacheLocation.Any, Duration = 3600)] public JsController : Controller public ActionResult JQuery() { //I would have a ascx with the entire jquery script inside return View(); } and on the site.master: <%=Html.RenderAction("JQuery","JsController");

  • Manipulating data in sql / asp.net / c# - how?

    - by SLC
    Not sure how to word the question... Basically, so far all my SQL stuff has been stored procedures and dumped into a gridview. The odd case where I had to perform an action based on a value (such as highlighting a row green if a certain value was true) were done as the gridview was rendering in one of the overrides. Now however I have to do something far more complicated - pull three sets of data down, run a series of checks on all three and some date related checks and stuff, then populate a gridview with some of the items. In logic terms, I want to run three queries, and store the lists of results (presumably in Lists?) then run some logic, then populate the gridview. Specifically what I don't know how to do is: Best way of pulling the data, and putting it into a List or other datastructure that lets me easily run through it, and retrieve data based on column (myList.age, or more likely, myList["Age"]). One I have compared the data, I assume I create a new list that will be put into the gridview... how do I put the contents of a list INTO a gridview? How would I add other stuff such as buttons or checkboxes at the same time? Any nudge in the right direction would be appreciated! Particularly doing cool stuff with lists and sql (if there is anything cool you can do with them)

    - by Zaps
    Hi, I currently have 3 textbox controls on my page. I also have a required valdiator of each of the textboxes. However I only want the validator for a textbox to fire if there is text in either of the other 2 textboxes. If all 3 textboxes are empty then no validators should fire. Is there any way I can do this in javascript/jquery as I want the user to get the best experience possible. Any help would be greatly appreciated. Thanks in advance.

  • Resize images to fit image control in asp.net javascript

    - by tszoro
    I change an image in the header based on which menu item is selected. The problem is that the image stretches in the image control. I want it to automatically zoom without distorting the image. Is this possible. Note: The images reside in an images folder and are not all the same size. Javascript <script type="text/javascript"> function ChangeProjectImage(imgpath) { var img1 = document.getElementById("Image2") img1.src = imgpath; } </script>

  • I can't find the homepage for my ASP.NET MVC site :(

    - by Pure.Krome
    Hi folks, really simple question here. when I remove the default route, I returns an empty page to the browser :- routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); Now before everyone starts shouting "that's because that's the default route to access all action methods, etc.." .. i know that. My question is - what code / routes does the default framework try and call .. which makes that Default Route get used/kick in? Why? I don't wish to make that my default route regex (don't ask why - this is some R&D) but I still need the main home page .. ie. Home/Index . If i try and just add that route, it doesn't get called and an empty page is returned. So -- what does the framework try and call when a user doesn't provide any urls? It's like there's some secret default document stuff set up? Cheers :)

  • Elegant ways of displaying a GridView with lots of columns (ASP.NET)

    - by Chris
    Hi, just a general design question that I'd like to hear some of your opinions on. I am designing a system for a client, and I'm using GridView' a lot. They need a lot of columns to be displayed in some of these, and I've had to resort to using a panel with a horizontal scrollbar. This presents some issues - keeping track of which row is which is difficult, even with alternating row colours, and it's generally pretty ugly. How have you dealt with these issues before? Are there any sort of AJAX controls that could help, so some data could be only displayed on hover or such? Or any other general ideas.

  • ASP.NET 'Check all checkboxes' control

    - by RUiHAO
    I am using visual studio 2005 c#, and doing server side coding. I have a list of checkboxes in my gridview via checkbox template. I have tried to assign a checkbox in my header template, and assigned a checkbox_checkchange method to make it such that when the checkbox at the header is checked, the list of checkboxes in the template will be checked as well. However, it does not work and I am not able to spot the mistake. Below is my code for my checkbox in header template: protected void CheckAllCB_CheckedChanged(object sender, EventArgs e) { CheckBox chk = (CheckBox)GridView1.HeaderRow.FindControl("CheckAll"); if (chk.Checked) { for (int i = 0; i < GridView1.Rows.Count; i++) { CheckBox chkrow = (CheckBox)GridView1.Rows[i].FindControl("UserSelector"); chkrow.Checked = true; } } else { for (int i = 0; i < GridView1.Rows.Count; i++) { CheckBox chkrow = (CheckBox)GridView1.Rows[i].FindControl("UserSelector"); chkrow.Checked = false; } } } Thus I tried using a button to assign the checkall command instead. However, when I clicked on the button, the page does nothing but just refreshes itself. Below is my code for the checkall and uncheckall button: private void ToggleCheckState(bool checkState) { // Iterate through the Products.Rows property foreach (GridViewRow row in GridView1.Rows) { // Access the CheckBox CheckBox cb = (CheckBox)row.FindControl("UserSelector"); if (cb != null) cb.Checked = checkState; } } protected void CheckAll_Click(object sender, EventArgs e) { ToggleCheckState(true); } protected void UncheckAll_Click(object sender, EventArgs e) { ToggleCheckState(false); } Anyone can help me identify the mistake I did in my method? Thank you UserSelection GridView template:
