I'm trying to eliminate the tab that says table on the subgrids below. I've tried 

     template1.ShowChildViewCaptions = false;

     template1.MasterTemplate.ShowChildViewCaptions = false;

     grid.ShowChildViewCaptions = false;

     grid.MasterTemplate.ShowChildViewCaptions = false;

Nothing works. What am I doing wrong?

Thanks

Carl

Hello,
Currently using L4G (Version 11.7) in client mode (WebClient V11 on the PC)-server with a Pasoe configuration on the Linux server (where OpenEdge (DLC), PasOE, databases, and the _DB-REQUIRED program tree are located).
I need to migrate to version 12.2 + Telerik screen.
Do you have an example of a simple grid screen with CRUD management on a Be in client-server mode?
- Read the table: READ
- Create a record: CREATE
- Modify the table: UPDATE
- Delete a record: DELETE
Thank you

Is there an offline documentation package available for a specific version of Telerik UI for WinForms? I need a downloadable docs bundle so I can translate it into a specified language. The website only provides the latest documentation and examples, which is very inconvenient to use.

i have a  Master-Detail CRUD Job

Details shown using RADGRIDVIEW

for example :    Master is  "TBSYUSER" class     Detail is  "TBSYUSAU"  class   

change master will change  detail data

i using   BindingList<TBSYUSAU> -->  BindingSource -> RADGRIDVIEW

now if detail data's count varing a little large

ex: record count  change from  1 to 89  due to master change

RADGRIDVIEW refresh will take more times

should i change  strucuture to :    Datatable -->  BindingSource -> RADGRIDVIEW 

or have some suggestion  ?

I would like to expand a GridViewComboBoxColumn list on the same row where on another column that is set to "Lost". 

(see attached screenshot)
(1) User clicks on a cell and selects "Lost" from a list 

(2) From Cell Event, the "Reason" column (GridViewComboBoxColumn) is automatically expanded so the user knows to select a reason.


		private void dgvSales_CellValidating(object sender, CellValidatingEventArgs e)
		{
			if(e.ColumnIndex >= 0 && e.RowIndex >= 0)
			{

				switch (e.ColumnIndex)
				{
					case int _ when e.ColumnIndex == dgvSales.Columns["colWonLost"].Index:
						if(e.Value.ToString() == "Lost")
						{
							dgvSales.CurrentRow.Cells["colReason"].IsSelected = true;
							
							//Add code here to expand colReason list


							return;
						}
						break;
					default:
						break;
				}
			}

		}  //dgvSales CellValidating

Hi

I notice in the release notes for WinForms 2025.4.1321 that the upcoming release (Q2 2026) will no longer support Windows 7 theme (amongst others). My desktop application make extensive use of this theme, including mimicing the colours used by th etheme in other custom controls.

What is exactly meant by "Support for existing controls using these themes will remain unchanged."? Will my existing application work as before without changes for this and following releases of WinForms?

Cheers
Toby

I searched and searched and this answer was answered back in 2023 but not from a code perspective.

How do I change the font fore color (via code) for the group caption? CaptionFill is for the backcolor. Got it. I have spent hours trying to find it in this website and searching. Why does Telerik make things so difficult?
