GridControl : Selection problem

[Administrator]

I have a grid where ListBoxSelectionMode is set to SelectionMode.One;
The user can select any row greater then 3

private void Grid_SelectionChanging(object sender, GridSelectionChangingEventArgs e)
{
if (e.Range.IsRows && e.Range.Top < 3)
{
e.Cancel = true;
}

}

private void Grid_CurrentCellMoving(object sender, GridCurrentCellMovingEventArgs e)
{
if (e.RowIndex < 3)
e.Cancel = true;
}



Everything ok so far.

Now the problem is that on row 2 there is 1 cell containing a combobox used for filtering the grid.

I cannot access that combobox because the 2 events prevents me from selecting it.

Is there workaround for this ?

Hi Gert,

Thank you for your interest in Syncfusion products.

You need to check whether celltype of the current cell is "ComboBox" before

setting e.Cancel as true in CurrentCellMoving event to solve this issue. Here is

the modified code.

 void gridControl1_CurrentCellMoving(object sender, 

GridCurrentCellMovingEventArgs e)
 {
  if (e.RowIndex < 3)
  {
   //You need to check whether current celltype is "ComboBox"                

   if(this.gridControl1.Model[e.RowIndex,e.ColIndex].CellType!="ComboBox")
     e.Cancel = true;
  }
 }

 void gridControl1_SelectionChanging(object sender, 

GridSelectionChangingEventArgs e)
 {
  if (e.Range.IsRows && e.Range.Top < 3)
  {
   e.Cancel = true;
  }
 }

Please let me know if this helps.

Best Regards,

thx Srirajan for the quick reply.

That worked. 1 other issue :

I have set the property
Grid.ListBoxSelectionMode = SelectionMode.One;

But when the user selects the combobox in the header I don't want to higlight the entire header. Is it possible to avoid this ?

Hi Gert,

Thank you for your continued interest in Syncfusion products.

Please try this code to avoid selection of entire row when a combobox cell is selected in the header. The below code working for me. If you are again facing the same issue, Is it possible for you to upload a minimal sample which reproduces this issue?. That will help us to analyze this issue further.

 void gridControl1_SelectionChanging(object sender, GridSelectionChangingEventArgs e)
 {
   Console.WriteLine("Fire");
   if (e.Range.IsRows && e.Range.Top < 3)
   {
    e.Cancel = true;
   }
 }

Please let me know if this helps.

Best Regards,
Srirajan.
