Contains filter for Integer Column

[Dheeraj]

Hi,
       I have bit unusual requirement. I have to apply "contains" as default filter for an Integer data type column( with AutoPostBackOnFilter="true").

Please help me regarding this.

Hello Dheeru y,

One option to accomplish the desired functionality is to use the approach described in this help article:

Custom option for filtering (FilterListOptions -> VaryByDataTypeAllowCustom)

Here are some sample code snippets:

<telerik:GridBoundColumn DataField="MyIntegerColumn" UniqueName="MyIntegerColumn" HeaderText="MyIntegerColumn" FilterListOptions="VaryByDataTypeAllowCustom"
               AutoPostBackOnFilter="true" ShowFilterIcon="false" CurrentFilterFunction="Custom">
</telerik:GridBoundColumn>

Code behind:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.FilterCommandName)
    {
        Pair filterPair = (Pair)e.CommandArgument;
        if (filterPair.First.ToString() == "Custom")
        {
            e.Canceled = true;

            //Filter the data source here

            RadGrid1.Rebind();
        }
    }
}

I hope this helps
