GridViewCommandColumn PerformClick

[Roberto Wenzel]

Hello,

I need some help with my application code.

I'm trying to do a PerformClick on a CommandColumn in a single row in a single cell.

How can I access the ButtonElement in that cell and do a PerformClick event programmatically?

Thanks in advance

Roberto

Hello Roberto,

Since RadGridView is using UI Virtualization you cannot directly access the button. In your case you can just raise the CommandCellClick event which is the default action:

private void RadButton1_Click(object sender, EventArgs e)
{
    GridViewCellEventArgs args = new GridViewCellEventArgs(radGridView1.Rows[4], radGridView1.Columns[4], radGridView1.GridViewElement.ActiveEditor);
    radGridView1.MasterTemplate.EventDispatcher.RaiseEvent<GridViewCellEventArgs>(EventDispatcher.CommandCellClick, radGridView1, args);
}

I hope this will be useful. Let me know if you have additional questions.

Hello Dimitar,

thank you very much for your reply. That looks quite good. Unfortunately I always get an error with the GridViewElement.ActiveEditor which seems to be Nothing (in VB).

This is my code (translated into VB)

Private Sub AutoClick(ByVal rowindex As Integer, ByVal colindex As Integer)
    Dim args As GridViewCellEventArgs = New GridViewCellEventArgs(rgv_Prefixes.Rows(rowindex), rgv_Prefixes.Columns(colindex), rgv_Prefixes.GridViewElement.ActiveEditor)

rgv_Prefixes.MasterTemplate.EventDispatcher.RaiseEvent(Of GridViewCellEventArgs)(EventDispatcher.CommandCellClick, rgv_Prefixes, args)
End Sub

 

When runnig the code GridViewElement.ActiveEditor is always Nothing. Any idea?

Cheers Roberto

Hello Roberto,

Actually, this is expected at this point because the grid is not focused when the event is raised (the grid has ActiveEditor only when a cell value is edited). However, this should not stop you to execute the event.  

Please do not hesitate to contact us with any additional questions or concerns.

Hello Dimitar,

thanks again.

Unfortunatelly the code is not executed and throws an exception when GridViewElement.ActiveEditor is Nothing.

I will find another solution for my problem.

Thank you Roberto

Hello Roberto,

I have attached a small sample that shows how this works.

In addition please make sure that the correct row/column indexes are passed. 

I hope this will be useful.
