Drop Down List Filter - Value to Clear

[Chris]

I successfully implemented a custom filter class which manipulates a drop down list of possible values

https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/how-to/Filtering/filter-with-ms-dropdownlist-instead-of-textbox-

one thing remains - what should the value be to clear the filter - and do I need to add code to the class selected index event handler?

the example clears the textbox for all selections - but can't I selectively clear a filter?

Hi Chris,

One option to clear the filter value is to add a list item to the DropDownList with an empty value as demonstrated in the Grid - Filter Templates demo. You can also add an "x" button next to the DropDownList when there are filters applied, and by clicking on it, clear the filter of that specific column.

Please give the above suggestion a try and see if works for you.

I already had a blank list item as the first item

I added code in the custom filter class selected item event handler to use the "No Filter" option

Hi Chris,

I've prepared a basic sample project resembling the described scenario and attached it to my response. Please check it out to see how the filtering is handled as well clearing the filter values.

I hope this will prove helpful.
