[Solved] Moving column to end of grid

[Jerry Kurata]

Hi,

I want to move one of my dynamically added column's to the rightmost position in my grid.  After adding the columns to my grid I thought I could execute the following line to do this.

gridSAR.Columns[MyColumnName].DisplayIndex = gridSAR.Columns.Count - 1;

However, the line throws the exception "index out of range.  Must be non-negative and less that the size of the collection. Parameter name: Index".  Thinking that it might be named based indexing into the collection that was failing I modified the code to be:

int OldDisplayIndex = gridSAR.Columns[MyColumnName].DisplayIndex;
int MaxIndex = gridSAR.Columns.Count -1;
gridSAR.Columns[MyColumnName].DisplayIndex = MaxIndex ;

The variable OldDisplayIndex is set to 16 and MaxIndex is set to 21.  Setting of the DisplayIndex still throws the exception!

I don't see how this possible.   Any thoughts?
