           In radgrid i have a column called Employee names in this i will get the value as Employee1|Employee2|Employee3. I need the color change for the value Employee1 should be red color and Employee2 should be Green color and Employee3 should be Blue in color. Please Help me out.

Can you help me figure out what I have to do in radgrid?

Thank you,

I have a RadScheduler  with a RadSchedulerContextMenu that shows when the user right clicks an appointment. Inside that RadSchedulerContextMenu, I have several RadMenuItems, some of which are disabled. One of the RadMenuItems is Text="Edit" Value="CommandEdit" Enabled="False", however, it is NOT disabled. The other items are disabled when I set Enabled="false", but not the Edit item.

<telerik:RadSchedulerContextMenu runat="server" ID="ContextMenuNone" Skin="Vista" >  
<Items>    
<telerik:RadMenuItem Text="Edit" Value="CommandEdit" ImageUrl="~/edit.png" Enabled="false" />    
...
</Items>
</telerik:RadSchedulerContextMenu>

 
How can I disable the CommandEdit RadMenuItem?

I have the calendar set to allow multiple selection. Each selected day is going to be stored in the db. The issue I am having is determining what date was unselected from e.SelectedDates. I have found no other function/property to detemine this value.

My goal is simular to this. but even this does not allow me to know what the unselected date was.

I am using VS2005 telerik version 2008.1.619.20. I cannot upgrade.

Thanks

Hi,

Am I missing something? The $find is not working for a RadPanelBar, here is the code:


I tried to put the script block on the header tag and in the body tag. If I replace by $get, it works, but then I can't access the findItemByText function. The funny thing is that I use a very similar code on other page and it works, the difference is that I use a RadMenu instead a RadPanelBar.

On, the call to checkMain() would be on the onload event of the body, I tried to move around to see if there was something to do with the timing of this call, but no luck.

Any help is appreciated.

Thanks,
Eduardo

If you change your example page to have the following code-up front code.  When you expand the hierarchical item "About us" the child group height setting goes out the window (see attached img).  Is there anyway around this?

Hello Telerik Team,

I have a grid that I bind on the client side.

I want to create a custom filtering column for my grid.  I have successfully derived from GridBoundColumn to create GridFilteringBoundColumn.  I override the SetupFilterControls method and all is well.

However, I also have a GridButtonColumn that I would like to be able to filter on.  If I derive from GridButtonColumn in the same exact way as above, the cells do not get rendered as hyperlinks and clicking on the text in the cell does nothing (I expect it to do a fireCommand with my command name that I assigned.

I have verified with a debugger that the CommandName property is set correctly but I can't figure out why the cells do not render properly. In the browser, when I use the Telerik GridButtonColumn, the cells all contain text of this form:


but with my derived Column, all I get is simpletext after the grid binds on the client side.

What am I missing?

Thanks
Bob

Hi,

I need to create a combobox with variable number of columns.  Both the number of columns, and the column names would be determined only at run time.  Also, I need the combobox to be a multiselect combo, so I need to put in a checkbox in the item template.  So, I am creating the item template and header template at runtime. 

When I run the code, I am getting the error "Multiple controls with the same ID 'chkSourceElementValue' were found. FindControl requires that controls have unique IDs."  where chkSourceElementValue is the ID of the checkbox thats created in the item template.  I am setting the item template, header template, data source at page_load and also data binding it at that point.  I have enclosed snippets of my code, as well as the error message stack below.  it looks like the error is originating from within RadComboBox. 

I am using the latest version of Telerik ASP.NET AJAX Controls (ASP.NET AJAX Q3 2010 NET 35)

Please advise at the earliest.  Thank you.
