    I also require that BasketsCaughtTotal must always be equal to or greater than BasketsSampledTotal

    <Columns>
                         <telerik:GridBoundColumn DataField="TripCode" FilterControlAltText="Filter TripCode column" HeaderText="Trip Code" SortExpression="TripCode" UniqueName="TripCode" ReadOnly="true"></telerik:GridBoundColumn>
                         <telerik:GridBoundColumn DataField="VesselCode" HeaderText="Vessel" UniqueName="VesselCode" Visible="false" ReadOnly="true"></telerik:GridBoundColumn>
                         <telerik:GridBoundColumn DataField="HaulNumber" HeaderText="Haul" UniqueName="HaulNumber" ReadOnly="true"></telerik:GridBoundColumn>
                         <telerik:GridBoundColumn DataField="RigNumber" HeaderText="Rig"  UniqueName="RigNumber" ReadOnly="true"></telerik:GridBoundColumn>    
                         <telerik:GridBoundColumn DataField="CatchTypeName" HeaderText="Catch Type" UniqueName="CatchTypeName" ReadOnly="true"></telerik:GridBoundColumn>
                         <telerik:GridBoundColumn DataField="CatchTypeCode" HeaderText="Catch Type Code" Visible="false" UniqueName="CatchTypeCode" ReadOnly="true"></telerik:GridBoundColumn>
                         <telerik:GridCalculatedColumn HeaderText="Raising Factor" UniqueName="RaisingFactor" DataType="System.Decimal" DataFormatString="{0:N2}" DataFields="BasketsCaughtTotal, BasketsSampledTotal" Expression="{0}/{1}" />
                         <telerik:GridBoundColumn DataField="BasketsCaughtTotal" HeaderText="Baskets Caught Total" UniqueName="BasketsCaughtTotal" ColumnEditorID="BasketsCaughtTotal" Visible="false" DataType="System.Decimal" DataFormatString="{0:N5}">
                              <ColumnValidationSettings EnableRequiredFieldValidation="True">
                                   <RequiredFieldValidator ID="RFTotalBasketsCaught" Font-Bold="True"> Enter baskets caught</RequiredFieldValidator>
                               </ColumnValidationSettings>
                         </telerik:GridBoundColumn>
                         <telerik:GridBoundColumn DataField="BasketsSampledTotal" HeaderText="Baskets Sampled Total" UniqueName="BasketsSampledTotal" ColumnEditorID="BasketsSampledTotal" Visible="false" DataType="System.Decimal" DataFormatString="{0:N5}">
                              <ColumnValidationSettings EnableRequiredFieldValidation="True">
                                   <RequiredFieldValidator ID="RFTotalBasketsSampled" Font-Bold="True"> Enter baskets sampled</RequiredFieldValidator>
                               </ColumnValidationSettings>
                         </telerik:GridBoundColumn>
                        </Columns>

    Hi Ida,

    You can add the CompareValidator in the ItemCreated event as follows:

    C#:
    protected void RadGrid1_ItemCreated1(object sender, GridItemEventArgs e)
    {
       if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem item = e.Item as GridEditableItem;
            TextBox BasketsCaughtTotal = (TextBox)item["BasketsCaughtTotal"].Controls[0];
            TextBox BasketsSampledTotal = (TextBox)item["BasketsSampledTotal"].Controls[0];
            TableCell cell = (TableCell)BasketsCaughtTotal.Parent;
            CompareValidator val = new CompareValidator();
            val.ControlToValidate = BasketsCaughtTotal.ID;
            val.ControlToCompare = BasketsSampledTotal.ID;
            val.Operator = ValidationCompareOperator.GreaterThanEqual;
            val.ErrorMessage = "Should be Greater than or Equal to BasketsSampledTotal";
            val.ForeColor = Color.Red;
            cell.Controls.Add(val);
        }            
    }

    Thanks,
    Princy

    Thank you Princy. Would it be ok to have this code in VB.Net?

    My apologises - I should have specified I required code to be in VB.Net.

    Thank you, Ida

    Hi Ida,

    Here is the code in VB. You can use this Code-Converter to covert to VB and vice-verse.

    VB:
    Protected Sub RadGrid1_ItemCreated1(sender As Object, e As GridItemEventArgs)
        If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
            Dim item As GridEditableItem = TryCast(e.Item, GridEditableItem)
            Dim BasketsCaughtTotal As TextBox = DirectCast(item("BasketsCaughtTotal").Controls(0), TextBox)
            Dim BasketsSampledTotal As TextBox = DirectCast(item("BasketsSampledTotal").Controls(0), TextBox)
            Dim cell As TableCell = DirectCast(BasketsCaughtTotal.Parent, TableCell)
            Dim val As New CompareValidator()
            val.ControlToValidate = BasketsCaughtTotal.ID
            val.ControlToCompare = BasketsSampledTotal.ID
            val.[Operator] = ValidationCompareOperator.GreaterThanEqual
            val.ErrorMessage = "Should be Greater than or Equal to BasketsSampledTotal"
            val.ForeColor = Color.Red
            cell.Controls.Add(val)
        End If
    End Sub

    Thanks,
    Princy

    I have two GridDateTimeColumn in RadGrid1

    <telerik:GridDateTimeColumn DataField="FromDate" DataFormatString="{0:d}" FilterControlWidth="98px" HeaderButtonType="TextButton" HeaderStyle-Width="125" HeaderText="From Date ">
    <ColumnValidationSettings EnableModelErrorMessageValidation="true" EnableRequiredFieldValidation="true">
    <RequiredFieldValidator ErrorMessage="* required" ForeColor="Red"></RequiredFieldValidator>
    <ModelErrorMessage BackColor="Red" />
    </ColumnValidationSettings>
    </telerik:GridDateTimeColumn>
    <telerik:GridDateTimeColumn DataField="ToDate" DataFormatString="{0:d}" FilterControlWidth="98px" HeaderButtonType="TextButton" HeaderStyle-Width="125" HeaderText="To Date">
    <ColumnValidationSettings EnableModelErrorMessageValidation="true" EnableRequiredFieldValidation="true">
    <RequiredFieldValidator ErrorMessage="* required" ForeColor="Red"></RequiredFieldValidator>
    <ModelErrorMessage BackColor="Red" />
    </ColumnValidationSettings>
    </telerik:GridDateTimeColumn>

     

    And I want to add compareValidator in RadGrid1_ItemCreated. Like this

     

    Private Sub RadGrid1_ItemCreated1(sender As Object, e As GridItemEventArgs) Handles RadGrid1.ItemCreated
    If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then

    Dim fromDatecolumnEditor As GridDateTimeColumnEditor = TryCast(DirectCast(e.Item, GridEditableItem).EditManager.GetColumnEditor("FromDate"), GridDateTimeColumnEditor)
    Dim toDatecolumnEditor As GridDateTimeColumnEditor = TryCast(DirectCast(e.Item, GridEditableItem).EditManager.GetColumnEditor("ToDate"), GridDateTimeColumnEditor)
    Dim datecell As TableCell = DirectCast(toDatecolumnEditor.PickerControl.Parent, TableCell)
    Dim compareValidator As New CompareValidator()

    compareValidator.ID = "compareValidator"
    compareValidator.ControlToValidate = toDatecolumnEditor.PickerControl.ID
    compareValidator.ValueToCompare = fromDatecolumnEditor.PickerControl.ID
    compareValidator.[Operator] = ValidationCompareOperator.GreaterThanEqual
    compareValidator.Type = ValidationDataType.[Date]
    compareValidator.ForeColor = Drawing.Color.Red
    compareValidator.ErrorMessage = "To date must be later than from date."
    datecell.Controls.Add(compareValidator)

    End If

    But, it is not work. Please help.

    It works if make change to

    'compareValidator.ValueToCompare = DateTime.Now.ToShortDateString

    Hi Yueming,

    Generally, we suggest that you use the built-in range filtering of GridDateTimeColumn as stated in the following post:
    http://marketplace.telerik.com/forums/filtering-issues-f154584cbb0b#K4cEr7lxV0O0GYt4ib3GrA

    Alternatively, you can check the RadFilter control if you want to provide the filtering capability outside the grid:
    http://demos.telerik.com/aspnet-ajax/filter/examples/integration/defaultcs.aspx?product=filter

    I hope this will prove helpful.
