Iterating through columns in a GGC and checking if a column has a dropdown list

[Thabo]

Hi,

Assuming i have 4 columns and one of them has a dropdownlist. Is there a way to iterate through the columns in the GridGroupingControl until i come across the column that has the dropdown list.

Also, how do i check if a column has a dropdown list?

Where do you want to do this?

You can always iterate through the grid.TableDescriptor.VisibleColumns.

foreach(GridVisibleColumnDescriptor cd in this.gridGroupingControl1.TableDescriptor.VisibleColumns)
{
	// cd.Name has column name
        //this.gridGroupingControl1.TableDescriptor.Columns[cd.Name].FieldDescriptor has the filed
}

But if you are in some event, there may be a simpler way to get at this information through the event args.

I would actually like to di it in an event that''s caught when a row is deleted from a GridDataBoundGrid.
By the way, can you also tell me which event handler is suitable when deleting a row.

I''m not sure if the RowsDeleted is the correct one to use

I am confused. The first question asks about a GridGroupingControl and this one mentions a GridDataBoundGrid. Exactly how you do this depened upon what grid you are using.

Sorry, my mistake, i''m actually using a GroupDataBoundGrid. Another thing is that, while iterating through the columns, i''d like to break when i come across a column that has a dropdown list.

So what i really want is code sample that iterates through the columns of a GroupDataBoundGrid and at the same time checks if the cells of a column have a dropdown list.

foreach(GridBoundColumn col in this.grid.GridBoundColumns)
{
   if(col.StyleInfo.CellType == "ComboBox")
   {
       Console.WriteLine("This is a combobox");
   }
}
