Set width to columns in MultiColumnBox inside RadGridView

[Kamran Hussain]

Hi...

 I have a MultiColumnBox in RadGridView and i have three columns in the MultiColumnBox. I am unable to find any property that sets their width. there is a width property that sets the overall MultiColumnBox width but no proerty that set the inner columns ( database fields it contains ) width....

Hi Kamran Hussain,

Thank you for your question.You can access the inside grid control in the RadMultiColumnComboBoxElement and set its columns properties. Please, consider the following code:

void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    RadMultiColumnComboBoxElement element = this.radGridView1.ActiveEditor as RadMultiColumnComboBoxElement;
    if (e.ColumnIndex == 5 && element != null)
    {
        element.EditorControl.Columns[0].Width = 120;
    }
}

I hope this helps. Do not hesitate to contact me again if you have other questions.
