HI,

I am building one radgrid with dynamic column creation. i.e I am binding dynamic columns in code behind file. I have declared grid as follows.

<

telerik:RadGrid ID="radgrdClaimsAvailable" runat="server" Skin="Office2007" GridLines="None" AllowPaging="true" PageSize="10" AutoGenerateColumns="true">

 

 

<HeaderStyle BackColor="#E3EAF1"></HeaderStyle>

 

 

<ClientSettings EnablePostBackOnRowClick="true">

 

 

<Selecting AllowRowSelect="True"></Selecting>

 

 

</ClientSettings>

 

 

<MasterTableView PagerStyle-AlwaysVisible="true" PagerStyle-Mode="NextPrevNumericAndAdvanced" AllowPaging="true" AllowSorting="true">

 

 

</MasterTableView>

 

 

</telerik:RadGrid>

 

Now I want hide one column. How can I achieve this through code behind. When I put following line of code in Grid PreRender, ColumnCreated, Page Prerender Completed event events it is throughing exception like:

Code:

If

radgrdClaimsAvailable.Columns.Count > 2 Then

 

radgrdClaimsAvailable.Columns(1).Display =

False

 

radgrdClaimsAvailable.Columns(2).Display =

False

 

 

End If

 

Exception:

Failed accessing GridColumn by index. Please verify that you have specified the structure of RadGrid correctly.

Please Help me in Hiding the columns in CodeBehind for RadGrid.

Thanks in Advance,
Medac

Here is my javacript  that open radwindow
  function RadWindowOpenCourseContinuen(num, cid) {
                var wnd = $find("<%=modalPopup.ClientID %>");
                wnd.setUrl("test.aspx");
                wnd.show();
                return false;
            }
Here is button that open radwindow
  <asp:Button ID="btnContinue" runat="server" CssClass="button" TabIndex="37" Text="Click here to continue..."
                                            OnClientClick="RadWindowOpenCourseContinuen(); return false; " />
Here is my code behind part
  string strhtmlnew = "javascript:RadWindowOpenCourseContinuen('1','" + Session["CID"] + "');";
 btnContinue.Attributes.Add("onclick", strhtmlnew);
Problem is not passed argument simple open test page

The following controls position correctly when the DatePopupbutton visible property is true
The labels are directly above the datepicker controls using IE 6 and firefox 3.04
But when I set the visible property to false then the controls are not positioned the same between the two browsers?????

Hello,
I wanted to know if it is possible to force the suggestion research elements with javascript code without depending on the filter?
I looked to see if it is possible to disable the filter method as:
[ Filter ="none" ] , but it is impossible.. only Filter="Contain" or Filter="StartWith".
I was wondering if you know a javascript function that could allow to force the display of the popup ? Or disable the filter.To see all the proposed elements when the user takes the focus of the field.
Thanks a lot..

In edit mode of telerik text editor text alignment is working but after publish and re edit  it not working.

hi,
I have a rad window which opens on button click. It has many text boxes.
I want to pass text boxes value to its parent page.
I wrote this code in popup

 function returnToParent() 
                  {
                                     
                    var oArg = new Object();
                     oArg.txtRateType=document .getElementById ("txtRateType").value;
                
                   
                    oArg.txtLabourWeekdayTotal=document .getElementById ("txtLabourWeekdayTotal").value;
                    oArg.txtLabourSaturdayTotal=document .getElementById ("txtLabourSaturdayTotal").value;
                  var oWnd = GetRadWindow();
 oWnd.close(oArg);
}
I m calling this funtion on submit button of this form.

Then on parent page,i have defined

<telerik:RadWindowManager ID="RadWindowManagerServiceReportDetails" runat="server" OnClientPageLoad="OnClientPageLoad"  Font-Names="Arial, Helvetica, sans-serif">
            <Windows >
                 <telerik:RadWindow ID="UserListDialogInvoiceWorksheet" runat="server"  Height="740px" 
                   Width="910px" ReloadOnShow="true" ShowContentDuringLoad="false" OnClientClose="OnClientCloseInvoicePopup" 
                   Modal="true" KeepInScreenBounds="true" Behaviors="Close,Move"  Font-Names="Arial, Helvetica, sans-serif" Font-Size="11 px" />
            </Windows>
    </telerik:RadWindowManager>

so when radwindow closes,this function gets called





  function OnClientCloseInvoicePopup(oWnd, args)
 {
             
               var arg = args.get_argument();
            
               if (arg) 
{
var  textBox = $find("<%=txtExitReportInvStandardDays.ClientID %>");
textBox.set_value(arg.txtLabourWeekdayTotal); 

var  textBox1 = $find("<%=txtExitReportInvPremiumDays.ClientID %>");
textBox1.set_value(arg.txtLabourSaturdayTotal)); 

}
}

but when if textbox is equal to null. and an error occurs 'null is null or not an object'.

please help me this problme.

Hi,

I created a gird which includes MasterGrid and Child Grid, However, I cannot clear the selected row after copy, move some row.

Could someone help me I really appreciate it.

Thank you.

I used an example found elsewhere on the Telerik forums to dynamically load user controls into a panel with a tabstrip control managing which control is loaded.

The original source gave two simple examples:
Default.aspx

TimerControl.ascx

and finally
SimpleControl.ascx

In the codebehind, the loaded control is determined from the viewstate, and I have successfully incorporated my controls in place of the two examples provided above. However, the entire page is being updated on postback.

In default.aspx I have set the ajax manager to update the tabstrip and panel and in my controls, I have set the ajax proxy to update only the controls that need to be updated, but it does not work correctly, still updating the entire page on each postback.

On another note, when I set OnTabClick to my click handler, I get a compile error indicating that the function is not part of the class. Removing it does not create a problem with the event firing, but I mention it because it may be the reason the entire page is updated.
