Hi;
I use GridBoundColumn in radgrid and edit like
this (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/alleditablecolumns/defaultcs.aspx) page.
But I want to change a textbox's size or I want to do textbox multiline.
You can also set the column editors declaratively by setting the ColumnEditorID property of the corresponding column to the ID of the custom column editor which will help you customize the look of the column editors easily. Refer to the following document to understand better: Declarative style editors
