SelectedIndexChanged in GridViewComboBoxColumn

[Sheraz Naseeb]

Hi Telerik Team,

I am struggeling with an issue, Actually I have a GridView in wich I have 5 different columns. One of these columns is a GridViewComboBoxColumn. My issue is I need to get the selected value of this combobox and set that value into the next column.

Is that possible to handle SelectedIndexChanged event of GridViewComboBoxColumn and also can we handle ItemDataBound event of GridViewComboBoxColumn.

Please help,

Many thanks

Hi Sheraz,

Thank you for writing.

In case you are using RadControls version 2009.1.414 as you pointed out in your support ticket info, the best approach to achieve the desired behavior is by subscribing for the CellEndEdit event. Please refer to the following code snippet:

void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)
{
    int destinationColumnIndex = e.ColumnIndex + 1;
    radGridView1.Rows[e.RowIndex].Cells[destinationColumnIndex].Value = radGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;
}

Private Sub radGridView1_CellEndEdit(sender As Object, e As GridViewCellEventArgs)
    Dim destinationColumnIndex As Integer = e.ColumnIndex + 1
    radGridView1.Rows(e.RowIndex).Cells(destinationColumnIndex).Value = radGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value
End Sub

On the other hand, I saw that you have downloaded also version 2010.2.10.713, and since we have made many improvements in our GridView since Q1 2009 the approach is different. Here is a snippet:

void radGridView1_CellValueChanged(object sender, GridViewCellEventArgs e)
{
   if (e.Column is GridViewComboBoxColumn)
   {
       radGridView1.Rows[e.RowIndex].Cells["DestinationColumnName"].Value = e.Value;
   }
}

Private Sub radGridView1_CellValueChanged(sender As Object, e As GridViewCellEventArgs)
    If TypeOf e.Column Is GridViewComboBoxColumn Then
        radGridView1.Rows(e.RowIndex).Cells("DestinationColumnName").Value = e.Value
    End If
End Sub

If you are using the old version of our controls, I highly recommend you to upgrade to the latest version, since many improvements and new features were added, and the whole control API was changed. Detailed information regarding the introduced changes of each release can be found in our Release Notes.

I hope you find this information helpful. In case you need any additional assistance, do not hesitate to contact us.

Sincerely yours,
