Setting the controlparameter of a ListBox which points to same RadGrid where the Listbox is used

I'm having trouble with the controlparameter of a ListBox which points to same RadGrid where the Listbox is used.

I want to populate the Listbox depending on the selected value of the Grid, so I've set a controlparameter in the datasource of the ListBox which points to the selectedItem of the Grid. However, the controlparameter always gets the default value. If I set the controlparameter to another grid (not the grid which is the parent of the ListBox) it works fine.

    
            <GRID id=g1 Datasource = DS1>  
        
                <VIEW> 
        
                <EDIT> 
        
                    <LISTBOX Datasource=DS2></LISTBOX> 
        
                  </EDIT> 
        
            </GRID> 
        
            <DS1> 
        
                ...  
        
            </DS1> 
        
            <DS2> 
        
                <selectparameters> 
        
                    <asp:ControlParameter ControlID="g1" DefaultValue="0" Name="id" PropertyName="SelectedValue" Type="Int32" />   
        
                </selectparameters> 
        
            </ds2>

__doPostBack(

"<%= this.UniqueID %>", "RowDblClicked:" + this.Rows[index].ItemIndex);

}
</script>
in client events I do,

and in ascx.cs file, I do this,

public partial class CPackageMainUserControl : BaseUserControl, IPostBackEventHandler
{

void IPostBackEventHandler.RaisePostBackEvent(string eventArgument)

{

string[] postBackEventArgumentData = eventArgument.Split(':');

switch (postBackEventArgumentData[0])

{

case "RowDblClicked":

m_ctlPackageGroupMultiView.SetActiveView(m_ctlPackageSetUpView);

m_ctlPackageSetupUserCtrl.LoadNonDocPredefinedReports();

break;

}

}
}

(because in my cause when i dbl click on a row in a radgrid , I need to setactiveview to openup another view).

controls collection cannot be modified

Hi,

I have upgraded RADControls - RADTreeView from ASP.NET to ASP.NET AJAX v2009.1.527.35.

I get the error "controls collection cannot be modified" when the page loads.

The RADControl declaration and associated code is given below.

                                <telerik:RadTreeView id="AllControlsTree" Runat="server" Width="99%" OnContextMenuItemClick="Tree_ContextMenuItemClick"         
                        OnClientContextMenuItemClicking="BeforeClientContextHandler" Height="60%"></telerik:RadTreeView>         
                        <TABLE cellSpacing="2" cellPadding="0" width="260">         
                        <TR>         
                          <TD onclick="AddControlsPostBack(<%= AllControlsTree.ClientID %>);" >Cell xxx         
                            Add Controls To Version         
                          </TD>         
                        </TR>         
                        </TABLE>         
                                 

Already tried

                                <telerik:RadTreeView id="AllControlsTree" Runat="server" Width="99%" OnContextMenuItemClick="Tree_ContextMenuItemClick"         
                        OnClientContextMenuItemClicking="BeforeClientContextHandler" Height="60%"></telerik:RadTreeView>         
                        <TABLE cellSpacing="2" cellPadding="0" width="260">         
                        <TR>         
                          <TD onclick="AddControlsPostBack($find('<%= AllControlsTree.ClientID %>')" >Cell xxx         
                            Add Controls To Version         
                          </TD>         
                        </TR>         
                        </TABLE>

[Solved] RadChart and Mono

Hi,

I have been trying to get RadChart working on Mono but no luck yet.

I am using a virtual machine which I downloaded from mono. For the most part all the controls work fine, just RadChart that doesn't. I get the following error:

The Chart http handler is not registered. Please, manually add the following line to your Web.config httpHandlers section:
<addpath="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler,Telerik.Web.UI, Version=2009.2.826.20, Culture=neutral,PublicKeyToken=121fae78165ba3d4" validate="false" />

Then I tried runnig it on another machine with Mono installed on Apache and I get the following:

gdiplus.dll

Description: HTTP 500. Error processing request.

Stack Trace:

System.DllNotFoundException: gdiplus.dll  at (wrapper managed-to-native) System.Drawing.GDIPlus:GdiplusStartup (ulong&,System.Drawing.GdiplusStartupInput&,System.Drawing.GdiplusStartupOutput&)  at System.Drawing.GDIPlus..cctor () [0x00000]

Version information: Mono Version: 2.0.50727.1433; ASP.NET Version: 2.0.50727.1433

Has anyone been able to get RadChart working on Mono?

Buttons on non-white background

Hi
I am using the excellent form decorator control in default skin on a page which has a
stone coloured background.
The result is white corners around buttons where the rounding has been done. Is there
any way to set the background colour of the button so that the square corners are effectively invisible?

Thanks

Clive

[Solved] How to make button Postback?

Hi,
I'm having fun with the grid and I can make it work fine.
I have a GridButtonColum with CommandName that I can pick up in MyRadGrid_ItemCommand. Thats good. But the command I'm running is a file download and I need PostBack. I have seached the forum and the documentation but nothing I try seems to work.

So how can I make the button do a full Postback ? If I disable Ajax completely the button works as expected.
