New windows appears behind active through OnRowClick

Hi,
it open a new window from a selected grid row through OnRowClick. The grid is part of the active window. The new window is opened behind the active window, even though it is set as active. Both windows are accessible. OnRowClick triggers the following client function ShowWin. When calling this function from a button (triggered through onclick), the new window appeares topmost.

function ShowWin(sender, eventArgs)
{
    var itemId = eventArgs.getDataKeyValue("itemId");
    var oWnd = GetRadWindow().BrowserWindow.radopen('/Data.aspx?itemId=' + itemId, null);
    oWnd.set_title('Edit data');
    oWnd.setSize(600, 400);
    oWnd.center();
    oWnd.setActive(true);
}

and in the grid

<ClientSettings EnableRowHoverStyle="True">
    <ClientEvents OnRowClick="ShowWin"></ClientEvents>
</ClientSettings>

Best regards

Unknown server tag in master page

Hi

I am experiencing a frequent problem in Visual Web Developer 2008 SP1 with RadControls q2 2009.
The problem is more of an annoyance than a killer issue.

Often when I open a site I am working on in vwd, pages that are working fine will show all the telerik controls
in the Master page (in design view) in boxes with 'Error Creating Control' ... An unhandled exception error has occurred. Unknown server tag
(etc etc)

This then takes up the screen real estate and makes the page look totally unlike the browser view.

I need to emphasis;
1 ) this does not always happen.
2 ) it does not affect the runtime behaviour. The controls are not really 'uknown' at all.

I have tried closing and reopening vwd, rebooting windows, and this sometimes works.

Can you suggest how I can fix this annoying problem?

Thanks

Clive

Export Hierarchical Grid

Hi,

I have a 2 level hierarchical grid which I am trying to export to excel. I have used the following code:

    
             protected void btnExport_Click(object sender, EventArgs e)  
        
                {  
        
                    try 
        
                    {  
        
                        rgScenario.ExportSettings.ExportOnlyData = true;  
        
                        rgScenario.ExportSettings.IgnorePaging = true;  
        
                        rgScenario.ExportSettings.OpenInNewWindow = true;  
        
                        rgScenario.MasterTableView.HierarchyDefaultExpanded = true;  
        
                        rgScenario.MasterTableView.Rebind();  
        
                        rgScenario.MasterTableView.ExportToExcel();  
        
                    }  
        
                    catch(Exception ex)  
        
                    {  
        
                    }

But I recieve the following runtime exception:

[NullReferenceException: Object reference not set to an instance of an object.]
   Telerik.Web.UI.GridTableView.PrepareExport() +47
   Telerik.Web.UI.Grid.Export.TableViewExporter.PrepareForExport() +340
   Telerik.Web.UI.Grid.Export.TableViewExporter.page_PreRender(Object sender, EventArgs e) +34
   System.EventHandler.Invoke(Object sender, EventArgs e) +0
   System.Web.UI.Control.OnPreRender(EventArgs e) +8679510
   System.Web.UI.Control.PreRenderRecursiveInternal() +80
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +842

Is there anything I have missed?

Saurabh

RadMenu AJAX full page refresh IE6

Hi,

I have a radMenu in a masterpage bound to an object datasource. When clicking on an menuitem in Internet Explorer 6 I get a full page refresh instead of just a contentpage refresh. This behavior is not the case in Internet Explorer 8, where only the contentpage is refreshed.

Any updates within the contentpage that have been AJAXified correctly only update the contentpage itself.

Any idea what could cause this behavior?

Cheers,
Roel

Postback not always firing wiht MarkFirstMatch

Hi:

If I use the MarkFirstMatch feature in data entry (just typing a 1, 2 or 3) the SelectedIndexChange event does not seem to fire. If I use the drop-down, then it fires.

    
            <telerik:RadComboBox ID="classComboBox" runat="server"  
        
                Skin="Outlook" Width="90px" 
        
                MarkFirstMatch="True" AutoPostBack="True" 
        
                OnSelectedIndexChanged="classComboBox_SelectedIndexChanged" 
        
                > 
        
                <Items> 
        
                    <telerik:radcomboboxitem Value="0" Text="0 None" /> 
        
                    <telerik:radcomboboxitem Value="1" Text="1" /> 
        
                    <telerik:radcomboboxitem Value="2" Text="2" /> 
        
                    <telerik:radcomboboxitem Value="3" Text="3" /> 
        
                </Items> 
        
            </telerik:RadComboBox>
