Hello everybody,

Can you tell me if exists the ActionOnLostFocus property in Winforms like Wpf ?

In fact, when I editing a cell I validating it in the CellValidating event or RowValidating.
But if during the editing I click on other control form's, the cell is not commited and the CellValidating event not fire.

How can I manage this situation appropriately?

Thank you
Best regards

Greetings,

Is it possible to edit UI elements of  of controls  programmatically ?

For instance, I want to change header font of a Radgroupbox.

I normally should open its smartTag and change the font within root elements. But how to do it programmatically ?

Can anyone help me identify which color setting needs to be changed if I want to change the (background?) color of the items in a CheckedDropDownList?  The default is an orange color that I'm not a big fan of.

 Hi ,

I am using the relational gridview. when i click the button , i want the node will be expanded by condition . Follow the link : https://docs.telerik.com/devtools/winforms/controls/gridview/hierarchical-grid/how-to/expanding-all-rows . is it the best way to do it ? because i see it is really slow when expanding.

 

void ExpandAllRows(GridViewTemplate template, bool expanded) {
 foreach(GridViewRowInfo row in template.Rows) {

  if(row.Tag == conditionID){
  row.IsExpanded = expanded;

 }
 }
 if (template.Templates.Count > 0) {
  foreach(GridViewTemplate childTemplate in template.Templates) {
   ExpandAllRows(childTemplate, true);
  }
 }
}
