[Solved] ColumnFilter Not Filtering

[Satya Sahu]

Hi Folks,

I have a RadGrid with few GridTemplateColumns.

But when i try its not filtering anything.

I can see the same data in my grid after selecting the filter content.

any help appreciated.

Thanks in Advance.

Hello Satya,

Filtering is automatically supported for Template columns. To allow filtering in template columns, you need only do the following:

1. Set the AllowFilteringByColumn property of the grid or table view to True.
2. Ensure that the AllowFiltering property of the template column is True
3. Set the DataField property of the template column to the field you want to use for filtering. 

Also checkout the following documentation for more information about this topic.

Hi,

From your column definition I have noticed that you havent set the DataField for the GridTemplateColumn.Please  set  the

ASPX:

 <telerik:GridTemplateColumn
   DataField="Country"
   HeaderText="Country">
 <HeaderStyle Width="30%" />
 <ItemTemplate>
   <img src='Img/<%# Eval("Country") %>.gif' alt="" style="vertical-align:middle;margin-right:7px;"/>
   <%# Eval("Country") %>
</ItemTemplate>
</telerik:GridTemplateColumn>
