Hi all!
I'm adding the filter for my RadGrid by set AllowFilteringByColumn="True"
However, it uses the textbox which is not good so much in some cases.
I see the RadComboBox allows user to search data by using its own Filter. So I would like to apply RadComboBox into the FIlter
Is there any ways to replace the textbox by RadComboBox ?
Thanks!
Andy.

Hello Andy,
In Telerik RadGrid you can enable dropdown filters for GridBoundColumns (or those columns which inherit from GridBoundColumns like GridDateTimeColumn, GridNumericColumn, etc.) and GridTemplateColumns declaratively - just set AllowFilteringByColumn = true for the entire grid and define FilterTemplate for the columns in question. Review the links below for more information:

Filter templates - help topic
I hope this helps.

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. 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). 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

Hello,
You can store the combo box selected value in session/ViewState, and in the PreRender event handler for the grid, get a reference to it, and restore its value.
