How to set ReadOnly to MultiColumn ComboBox

[Zan]

Hello Telerik Team,

I want all MultiColumn ComboBoxes in a form ReadOnly mode

foreach (Control ctrl in this.Controls)
{
  if (ctrl.GetType() == typeof(RadMultiColumnComboBox))
     ((RadMultiColumnComboBox)ctrl).ReadOnly = true;  //like that
}

However, ReadOnly property does not exist.

How can I set  MultiColumn ComboBox to ReadOnly ?

Hello,

RadMultiColumnComboBox currently does not have a read-only mode. To achieve it you should cancel the row changing by using the CurrentRowChanging event. In addition, you need to set the DropDownStyle to DropDownList:

public RadForm1()
{
    InitializeComponent();

    radMultiColumnComboBox1.EditorControl.CurrentRowChanging += EditorControl_CurrentRowChanging;
    radMultiColumnComboBox1.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

}

private void EditorControl_CurrentRowChanging(object sender, Telerik.WinControls.UI.CurrentRowChangingEventArgs e)
{
    e.Cancel = true;
}

Should you have any other questions do not hesitate to ask.
