I was looking for customCelltype where the control allows to select multiple item like (listbox) and put the selected values as comma separated value. since i didn't get this as part of your builtin control I was trying to use asp.net Server controls(in this case RadCombox or basic asp.net ListBox with selection mode="multiselect").
I was able to render the control by overloading the two methods
public Telerik.Web.UI.RadComboBox cbo = new Telerik.Web.UI.RadComboBox();
public override Control GetEditorControl(string id, TableCell parent, Appearance style, Inset margin, object value, bool upperLevel)
cbo.CheckBoxes = true;
cbo.DataSource = datasource;
public override Control PaintCell(string id, TableCell parent, Appearance style, Inset margin, object value, bool upperLevel)
on postback I am unable to acess the value. any help will be appreciated.
