  • Response.BinaryWrite calls the ASPX page twice

    - by Jon.ee
    I am trying to open a file in the browser using BinaryWriter. This causes the a dialog window to open and prompt the user to save or open the file. That behavior is fine; however, if I select open, the aspx page is called again and after a long wait the file finally opens. I set the ContentType Response.BinaryWrite(binary); Response.End(); Repsonse.Close(); This behavior only occurs with excel and word files. Browser IE8

  • Format decimal to currency, should be in cents for values $0 to $1

    - by Spongeboy
    I have a decimal variable which represents a donation amount. Currently I am displaying it on screen as a currency like so- DonationAmount.ToString("C"); This gives the following output (given a US locale) 1 -> $1.00 2 -> $2.00 0.5 -> $0.50 I am happy with the first two example, but want to have "0.5" show as "50c". My current solution is with a conditional- if (DonationAmount > 1) return (DonationAmount * 100m).ToString() + "c"; else return DonationAmount.ToString("C"); Is there a better way?

  • embedded wpf textbox does not accept input

    - by pro3carp3
    I put a wpf textbox inside a combobox to allow the user to enter a custom setting. I can read the keypress in the keydown event, but the text in the textbox does not change. What am I missing? <ComboBoxItem Name="GridSizeCustom"> <StackPanel Height="30" Orientation="Horizontal"> <TextBlock Text="Grid Size (8 - 200)" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0" /> <TextBox Name="GridSizeBox" KeyDown="test" Width="50" /> </StackPanel> </ComboBoxItem> I step through this event handler when I press a key, but no change to the textbox text: public void test(Object sender, KeyboardEventArgs e) { int x = 0; } Any help is appreciated. Thanks.

  • Alligator tags(<% %>) inside js string?

    - by bangoker
    I am trying to redirect a page reading the url from the config file. However, when I try this: <script type="text/javascript"> <%string redirectUrl = System.Web.Configuration.WebConfigurationManager.AppSettings["RedirectURL"];%> window.parent.location.replace("<%=redirectUrl%>"); </script> the alligator tags <% % are Not being highlighted, and when I run I get the following error in the yellow screen: the controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>). What am I doing wrong?? Thanks!

  • Gaining Reference to the Dialog from Dialog content

    - by coffeeaddict
    Here's my scenario: I've got a div on Page A. When an event happens (whatever I define, a click, whatever), I do a div.Dialog, set its properties and open it The data inside is returned from an async .ajax call that grabs the data from a url and appends it to the div by calling div.html(data) inside the .ajax callback, so it's essentially loading a PageB by getting the data (content) and appending it to the div that's calling the dialog("open")...nothing special here I don't think. My question: In Page B, how do I reference the dialog so I can do some things to it? For instance in Page B's content that I received back from that .ajax call and added to the div via .html(data), there is a button and when clicked I need to close the dialog. Right now my buttons are not working because one of them closes out the dialog and the other should redirect to a new page but both do not work now because I have no reference to the dialog that it's in to manipulate it.

  • Change css class depending on label's text

    - by abatishchev
    I have asp:Table with number of asp:Label inside asp:FormView, it represents short stats info. I need to set Label.CssClass to "red" if it's text isn't "0". Currently I do this on FormView.DataBound event. But think that it's better to use JavaScript and probably jQuery. How can I do that?

  • Problem with nhibernate join

    - by MexicanHacker
    I'm trying to do a join like this using fluent nhibernate: Id(x => x.Id); Map(x => x.SourceSystemRecordId,"sourceSystemRecord_id"); Then Join("cat.tbl_SourceSystemRecords", SourceSystemRecords); But, it seems I don't have a way to specify the column I want to join with from the first table, in this case I need to join on SourceSystemRecordId and not on Id Is there any way I can specify this? I tried References() but that requires me to create an object for this relationship, what I need is to aggregate the columns in sourcesystem records to the ones in the main table.

  • How do I tell if the ObjectDataSource OnSelected event was called for the selectmethod or selectcou

    - by itchi
    I have an object datasource that looks like this: <asp:ObjectDataSource ID="obdsList" runat="server" EnablePaging="True" SelectCountMethod="GetCountByID" SortParameterName="sortExpression" OldValuesParameterFormatString="original_{0}" SelectMethod="GetByID" TypeName="Services.Users" onselected="obdsList_Selected"> <SelectParameters> <asp:QueryStringParameter Name="ID" QueryStringField="ID" Type="Int32" /> </SelectParameters> </asp:ObjectDataSource> And a onselected event like this: protected void obdsList_Selected(object sender, ObjectDataSourceStatusEventArgs e) { } However, the event method is being called twice.. once with my returned list, and once with the returned Int32 count. If I want to cast e.ReturnValue to the return List how do I differentiate between the count and select methods? I can do a e.ReturnValue.GetType().ToString() but that seems like a hack.

  • What happens if an asynchronous delegate call never returns?

    - by RichardHowells
    I found a decent looking example of how to call a delegate asynchronously with a timeout... http://www.eggheadcafe.com/tutorials/aspnet/847c94bf-4b8d-4a66-9ae5-5b61f049019f/basics-make-any-method-c.aspx. In summary it uses WaitOne with a timeout to determine if the call does not return before the timeout expires. I also know that you should have an EndInvoke to match each BeginInvoke. So what happens if the wait timeout expires? We (presumably) DON'T want to call EndInvoke as that will block. The code can go on to do 'other things', but have we leaked anything? Is there some poor thread someplace blocked waiting for a return that's never going to happen? Have we leaked some memory where the result-that-will-never-return was going to be placed?

  • LINQ - 'Could not translate expression' with previously used and proven query condition

    - by tomfumb
    I am fairly new to LINQ and can't get my head around some inconsistency in behaviour. Any knowledgeable input would be much appreciated. I see similar issues on SO and elsewhere but they don't seem to help. I have a very simple setup - a company table and an addresses table. Each company can have 0 or more addresses, and if 0 one must be specified as the main address. I'm trying to handle the cases where there are 0 addresses, using an outer join and altering the select statement accordingly. Please note I'm currently binding the output straight to a GridView so I would like to keep all processing within the query. The following DOES work IQueryable query = from comp in context.Companies join addr in context.Addresses on comp.CompanyID equals addr.CompanyID into outer // outer join companies to addresses table to include companies with no address from addr in outer.DefaultIfEmpty() where (addr.IsMain == null ? true : addr.IsMain) == true // if a company has no address ensure it is not ruled out by the IsMain condition - default to true if null select new { comp.CompanyID, comp.Name, AddressID = (addr.AddressID == null ? -1 : addr.AddressID), // use -1 to represent a company that has no addresses MainAddress = String.Format("{0}, {1}, {2} {3} ({4})", addr.Address1, addr.City, addr.Region, addr.PostalCode, addr.Country) }; but this displays an empty address in the GridView as ", , ()" So I updated the MainAddress field to be MainAddress = (addr.AddressID == null ? "" : String.Format("{0}, {1}, {2} {3} ({4})", addr.Address1, addr.City, addr.Region, addr.PostalCode, addr.Country)) and now I'm getting the Could not translate expression error and a bunch of spewey auto-generated code in the error which means very little to me. The condition I added to MainAddress is no different to the working condition on AddressID, so can anybody tell me what's going on here? Any help greatly appreciated.

  • Linq to Entities (EF): How to get the value of a FK without doing the join

    - by Chu
    I'm using the Linq to Entities. I've got my main table, Employee setup with a field named vendorID. Vendor ID is a foreign key into the Vendors table. As it is right now, the Employee object does not directly expose the vendorID. Instead, I can only access it this way: var employee = (from e in context.Employees.Include("tbl_vendors") where e.employeeID = 1 select e).FirstOrDefault(); //this gets the vendor ID int vendorID = employee.tbl_vendors.vendorID; That is just fine and dandy, but it is extra work on the database because it is forcing a join where none is needed. Is there a way to get that key value without being forced to do a join to the tbl_vendors table?

  • jQuery ajax request response is empty in Internet Explorer

    - by Aprilia1982
    Hi, I'm doing the following ajax call: //exif loader function LoadExif(cImage) { $.ajax({ type: "POST", url: "http://localhost:62414/Default1.aspx/GetImageExif", data: "{iCurrentImage:" + cImage + "}", contentType: "application/json; charset=utf-8", dataType: "json", error: ajaxFailed, success: function (data, status) { var sStr = ''; for (var count in data.d) { sStr = sStr + data.d[count]; }; alert(sStr); } }); }; In Firefox the request works really fine. When I try to run the code in Internet Explorer, the response is empty. Here is the webmethod witch is called: <WebMethod()> _ <ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _ Public Shared Function GetImageExif(ByVal iCurrentImage As Integer) As String Dim sbTable As New StringBuilder sbTable.AppendLine("<table>") sbTable.AppendLine("<tr>") sbTable.AppendLine("<td>Name</td><td>" & gGallery.Images(iCurrentImage).File.Name & "</td>") sbTable.AppendLine("</tr>") sbTable.AppendLine("</table>") Return sbTable.ToString End Function Any ideas?
