Hello Jols,

You can check out the following document which explains on replacing the FilterTextBox with a DropDownList inorder to filter columns in the grid:
Filtering with MS DropDownList instead of textbox

Hi,
I am using a radcombobox for filtering radgrid. The filter works fine but after the selection of the radcombobox, it looses the selected value. This is probably happens because in the ItemDataBound event the radcombobox is populated again with the values. How can i keep the selected value?

Thanks a lot,
Angie

if (e.Item.ItemType == GridItemType.FilteringItem)
                        {
                            //
                            //Fill in the Consultation status ComboBox filter
                            //
                            GridFilteringItem filterItem = (GridFilteringItem)e.Item;
                            RadComboBox combo = (RadComboBox)filterItem["ConsultStatus"].FindControl("cboIcon");

                            RadComboBoxItem item = new RadComboBoxItem("");
                            combo.Items.Add(item);

                            item = new RadComboBoxItem("Όλα");
                            item.Value = "5";
                            combo.Items.Add(item);
}

Hi Princy,
I read your suggestion but i am using a completely different way in my rad combobox. In my case, each radcombobox item, contains an image and a title, that's why i fill in the radcombobox in the ItemDataBound event (so i can set the Item.Image value). Is there a way to keep the selected value?
Thanks again,
Angie
