    UltraWebGrid supports validators for columns, so you can just use RequiredFieldValidator to make sure the text entered for a columns is not empty (Null). Here is an example:

    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="UltraWebGrid1" runat="server" ErrorMessage="ErrorMessage" EnableClientScript=true Display=Static>
      </asp:RequiredFieldValidator>
        <igtbl:UltraWebGrid ID="UltraWebGrid1" runat="server" Height="200px" Width="325px"
            DataSourceID="SqlDataSource1">
            <Bands>
                <igtbl:UltraGridBand>
                    <Columns>
                        <igtbl:UltraGridColumn BaseColumnName="CustomerID" IsBound="True" Key="CustomerID">
                            <Header Caption="CustomerID">
                            </Header>                        
                        </igtbl:UltraGridColumn>
                        <igtbl:UltraGridColumn BaseColumnName="CompanyName" IsBound="True" Key="CompanyName">
                            <Header Caption="CompanyName">
                                <RowLayoutColumnInfo OriginX="1" />
                            </Header>
                            <Validators>
                                <igtbl:ValidatorItem  Value="RequiredFieldValidator1"  />
                            </Validators>
                             <Footer>
                                <RowLayoutColumnInfo OriginX="1" />
                            </Footer>
                        </igtbl:UltraGridColumn>
