I am having a radgrid with having  3 EditItemTemplate which uses 2 Combobox  and one RadTextBox . When the page is loaded for first time the insert/Add section on top of the grid is available . But after first insertion only the item binded is shown in the grid . The add section is not rendered . However on delete command the Add section reapper and I am able to add the items but then again on adding item insert row vanishes .

Hello,

I have a grid that uses "EditForms" to edit a record. What I would like to achieve is to disable filtering while the grid is in edit mode (both for adding a new record or editing an existing one)

Thank you,
