Validate Datetime Column before filter apply

[Le Danh]

If I input error value into "LastModifiedAt" column of RadFilter then the page happen error. How to validate this value before "OnApplyExpressions" event.

My coding is below:
    <telerik:RadFilter ID="RadFilter1" runat="server"  OnApplyExpressions="radFilterGridControl_SearchGridData">
        <FieldEditors>
            <telerik:RadFilterTextFieldEditor FieldName="LastModifiedAt" DisplayName="LastModifiedAt" DataType="System.DateTime" />
        </FieldEditors>
    </telerik:RadFilter>
               
    <telerik:RadGrid ID="radGridControl" runat="server" AllowFilteringByColumn="True" AllowPaging="True"
         AllowSorting="True"
        GridLines="None">
        <MasterTableView AutoGenerateColumns="False"  >
            <Columns>

                <telerik:GridBoundColumn DataType="System.DateTime" DataField="LastModifiedAt" HeaderText="LastModifiedAt" >
                </telerik:GridBoundColumn>
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>

Can you help me this problem?

Thanks,

Hello PhuongLD,

You should be using RadFilterDateFieldEditor instead. That will resolve the issue.
