Column cannot be added because its CellType property is null exception
- by niko
Hi,
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?
