Get ComboBox value on RowValidated

[Thomas Van den Bossche]

Dear Madam/Sir,

One column of my GridView is a GridViewComboBoxColumn.

GridViewComboBoxColumn companyClmn = new GridViewComboBoxColumn( COLUMN_COMPANY );
companyClmn.DataSource = this.transport.GetCompanies( this.username );
companyClmn.DisplayMember = "companyName";
companyClmn.FieldName = "companyID";
companyClmn.Width = 150;

I've added an event for RowValidated and want to check the value for this ComboBoxColumn
but I always get "Object reference not set...".
If I use a TextBoxColumn, I get the value without any problems.

private void SaveToDatabase( object sender, RowValidatedEventArgs e ) {

object value = e.Row.Cells[0].Value; // object reference not set...

}

Thanks in advance!

Edit: I've set .FieldName wrong... stupid error! Sorry!

Hi Thomas Van den Bossche,

Thank you for writing.

I have tested a similar scenario like the described and I have not experienced any issues when getting the ComoBoxColumn value. I am using the latest release Q3 2009 and the following code works as expected:

void radGridView1_RowValidated(object sender, RowValidatedEventArgs e)
{
    var value = e.Row.Cells["MyComboColumn"].Value;
}

Please, try this code with the latest release and let me know if you still experience any issues.

All the best,
