Controls[0] as TextBox. SetupFilterControls cell cell. RemoveAt 0 cell. CurrentFilterValue Is String. Empty Then CType cell. Controls 0 , TextBox. Once you have setup the layout of the filter template, the next part of the logic would be to handle the filtering for the grid. Below are two possible approaches which demonstrate how to do this.
The first approach utilizes an EntityDataSource, available under the 3. NET framework. We can use a RadCombobox to select the available items on which to filter, and nest it in the filter template of a template column, which would look something like:. When the user selects an item in the combo, the SelectedIndexChanged client side handler is raised. There, we get a reference to the masterTable client side object, and use its filter method, which in par with the EntityDataSource provides an almost codeless approach.
The EntityDataSource for the combo object is declared as shown below:. The second Grid in the demo presents this CheckList Filtering Note that the built-in filtering feature is not supported with simple data-binding calling DataBind. See the Simple data binding demo from the Populating with data section for more info about the limitations of this binding mode.

Hello Timothy, Column filtering, sorting and editing depends on the column Field. Well, I am afraid there is no such event. Even the filter template for the column requires a Field, otherwise it will not render.
