I am trying to keep the selected values in a RadComboBox (which are nested in a DataBoundGridColumn's FilterTemplate) from resetting to the 1st item in the list ("All" / Value=0) upon filtering the RadGrid (using filterExpression). I have tried setting the ViewState.ClientID to the selected value in the combobox, and have added a PreRender event handler to the HTML element. It does not seem that the PreRender event will fire withe the ComboBox nested in the FilterTemplate. Does anyone know a solution that would allow for the combobox selected item to remain the same after filtering the radGrid?
