Question

I have trouble with the following piece of code. When I go through with the debugger I get an exception when it comes to the following line:

dgvCalls.Columns.Insert(1, msisnnColumn); 

I get an exception:

Column cannot be added because its CellType property is null.

Oddly, I created the same procedure for some other DataGridViews and it worked fine.

if (!(dgvCalls.Columns.Contains('DirectionImage')))                 {                     directionIconColumn = new DataGridViewImageColumn();                     directionIconColumn.Name = 'DirectionImage';                     directionIconColumn.HeaderText = '';                     dgvCalls.Columns.Insert(0, directionIconColumn);                     directionIconColumn.CellTemplate = new DataGridViewImageCell();                 }                 if (!(dgvCalls.Columns.Contains('msisndColumn')))                 {                     msisnnColumn = new DataGridViewColumn();                     msisnnColumn.Name = 'msisndColumn';                     msisnnColumn.HeaderText = 'Klic';                     dgvCalls.Columns.Insert(1, msisnnColumn);                     msisnnColumn.CellTemplate = new DataGridViewTextBoxCell();                 } 

Any suggestions?

dgvCalls.Columns.Insert(1, msisnnColumn); msisnnColumn.CellTemplate = new DataGridViewTextBoxCell(); 

Try flipping those two lines. That might do the trick.
