from the modal on initiation not by button click.

Hi,
i have a problem retrieving a control that has been added at runtime into the place holder... Please provide help...

 <telerik:GridTemplateColumn HeaderText="Description" SortExpression="ProductName" UniqueName="ProductName2">
          <HeaderStyle HorizontalAlign="center" />
          <ItemStyle HorizontalAlign="Left" Width="700px" />
          <ItemTemplate>
          <table style="border:0px;" >
             <tr >
                 <td style="border:0px;">
               <asp:Label id = "lblProductDescription" runat = "server" Text = '<%# Eval("ProductName") %>'></asp:Label>
               </td>     
             </tr>                                                                                        
             <tr >
                 <td style="border:0px;" ID ="tdAttributes" runat = "server">
                 <asp:PlaceHolder id = "placeHolderAttributes" runat = "server" Visible = "false"></asp:PlaceHolder>
             </td> 
          </tr>  
         </table>                                                                                           
</ItemTemplate>
</telerik:GridTemplateColumn>

Control is added in ItemDataBound as. This code works,

</pre>
'htmltable,row and cells are declared
Select Case controltype
     Case ControlType.TEXTBOX 'Constants declared
          Dim textBox As Telerik.Web.UI.RadTextBox = New Telerik.Web.UI.RadTextBox
          textBox.ID = "MYCONTROL"
          tableCell.Controls.Add(textBox )
     Case ControlType.TEXTAREA
          Dim textBox As Telerik.Web.UI.RadTextBox = New Telerik.Web.UI.RadTextBox
          textBox.ID = "MYCONTROL"
          tableCell.Controls.Add(textBox )
     Case GlobalControls.UCFormFields.FormFieldTypes.CHECKBOX
     Case GlobalControls.UCFormFields.FormFieldTypes.DROPDOWNLIST
End Select             
thisHtmlTable.Rows.Insert(0, thisTableRow)
thisTableRow.Cells.Add(tableCell)
thisTableRow.Visible = True
thisHtmlTable.Rows.Insert(thisHtmlTable.Rows.Count, thisTableRow)
         
Dim placeHolder As PlaceHolder
placeHolder = gridItem.FindControl("placeHolderAttributes")
placeHolder.Controls.Add(thisHtmlTable)
placeHolder.Visible = True

In item command , i want to retrieve the control, i can switch between the controls if i retrieve the placeholder... my problem is that in itemcommand, i can retrieve the Placeholder but when i try placeholder.controls.count, it returns 0 and cannot retrieve any control

i am trying the following code in itemcommand

item("ProductName2").FindControl("placeHolderAttributes").Findcontrol("MYCONTROL")   'this throws an error
'also tried 
item("ProductName2").FindControl("placeHolderAttributes").controls.count 'this shows 0

Please provide help...
Thanks!!!

Hi Mark,
before the execution of the ItemCommand , you must redraw the grid as you are creating dynamic controls on ItemDataBound.

Regards,
Jamil

Hi,
Thanks for replying.
I am not sure on how to redraw the grid. i mean, i am not sure on which event to use for creating the controls, so that the controls are available for itemcommand.

Can u please provide a bit more detail.

Thanks again.
Mark

Hi, all,

I have an empty data message if there is no any records available. My problem is that the message is always put at top left, even I already HorizontalAlign="Center" and VerticalAlign="Middle".

Can you tell me how can I put it in the middle of Gridview?

Thanks

Use the CSSClass property to assign a style. You will have much better control over appearance.

Namespace not exposed in aspx.cs file

I am using .Net Framework 3.5, VS2008, C#, and ASP.Net

I cannot access a class that I defined in a class library project from an aspx.cs code-behind file. I am using the namespace "BusinessServices" in the class library, but when I try to use the namespace in the aspx.cs codebehind file (i.e "using BusinessServices") I get the error "The type or namespace name 'BusinessServices' could not be found (are you missing a using directive or an assembly reference?)".

I added a reference to the BusinessServices.DLL from the Add Reference Project tab, and I even tried to do it by browsing to the DLL. Nothing helps.

I am not sure what step I am missing.

Thanks.

Hi,

maybe the namespace you wish to use has no public classes/elements. Check, if the class you wanna
use is public.

Other than that, i suggest you create a simple sample project and try to reference the assembly and use the namespace there. Maybe this way you can exclude possible "maybe-problems" or provide us your sample.

Good Luck

Do you have an assembly directive similar to this ...

Well, dah! Do you expect ASP.NET to magically read your mind and know what item you intend to select Roll eyes | :rolleyes:

Also, you should use lstname.Item[i].selected not lstname.Item[i].selecteditem

Maybe you can rephrase your question and provide a working codeblock?

I'm trying to understand the problem, but unfortunately, i'm failing.

In general, if indeces of selected items cannot be retrieved, i would double check
the databinding on that listbox. if the listbox is rebound on that postback, you may lose
the selected item indeces.

try putting your databinding in an "if(!IsPostback)" block - if youre binding of course.

Good Luck

PopUp __dopostback

Hi everybody.

I need some help with a problem.

Can anybody say what's wrong with my script?
When executing, IE says that there is an error on the line with the __dopostback.
I do not have knowledge on javascript, but I copied the code and made it work sometimes.
Right now, I'm going crazy with it. Thanks in advance.

<script language="javascript"> 
      var sFeatures='dialogWidth: 500px;dialogHeight: 200px;status:no;scroll:no';
      var Resp = window.showModalDialog('PopUpMsg.aspx', window,sFeatures);
if (Resp == True)
{
       __doPostBack('btnBorrar','1');
}
</script>

It is supposed to show a modal window called PopUpmsg.aspx, where I'll answer Yes or No. That works fine. But after answering, I need to reload the page, and the postback does not seem to work.

You should use Page.GetPostBackEventReference.

Might be due to this browser cache. Are you uploading images with same name. If yes, try every time new name.
