Hello Rakesh,

After investigating this further, I determined that your requirement could be achieved by adding a RequiredFieldValidator the following way:

<ig:WebDataGrid ID=”wdg”>

. . .

</ig:WebDataGrid>

<asp:RequiredFieldValidator ID="Validator1" Text="Item is required" runat="server" ControlToValidate="wdg"></asp:RequiredFieldValidator>

A ValidatorId should also be added to the column, which is bound to the dropDown provider:

<ig:CellEditing >

    <ColumnSettings>

          <ig:EditingColumnSetting ColumnKey="DropDown1" EditorID="wdg_DropDownProvider1" ValidatorID="Validator1" />                                  

     </ColumnSettings>                               

</ig:CellEditing>

In order for this to work jQuery scripts should be added in the file and in the web.config in the configuration tag the following lines of code:

<appSettings>

    <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />

</appSettings>

Below I am attaching a sample demonstrating how this could be achieved. Please test it on your side and let me know if you need additional information regarding this matter.
