Radgrid not finding range validator

[John]

Hello all. Been trying to solve a problem to no avail. Have tried everything I can. Basically trying to set the minimun and maximum values of a range validator residing inside RadGrid. But it's not working.

Here is my code.

    <telerik:GridTemplateColumn DataField="claim_date" DataType="System.DateTime"
        FooterText="Totals: " HeaderText="Date" SortExpression="claim_date"
        UniqueName="claim_date">


        <ItemTemplate>
            <asp:Label ID="claim_dateLabel" runat="server"
                Text='<%# Eval("claim_date", "{0:MM/dd/yyyy}") %>'></asp:Label>

        </ItemTemplate>


        <EditItemTemplate>
                        <telerik:RadDatePicker ID="claim_dateTextBox" runat="server" DBSelectedDate='<%# Bind("claim_date") %>' Width="100" />

             <asp:RequiredFieldValidator ID="fvDateRequiredFieldValidator" runat="server" ErrorMessage="Claim date is required" ControlToValidate="claim_dateTextBox" ValidationGroup="DataEntryChk" Display="Dynamic" Font-Bold="true"  />

<asp:RangeValidator ID="fvDateValidator" Type="Date" ControlToValidate="claim_dateTextBox" runat="server" ErrorMessage="Cannot save claim item. Please select/enter a date in the same month as the voucher month." SetFocusOnError="True" ValidationGroup="DataEntryChk" Display="Dynamic" Font-Bold="true"  />

        </EditItemTemplate>


    </telerik:GridTemplateColumn>

And in code behind I have the following.

Protected Sub ClaimsGV_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles ClaimsGV.ItemCommand


    If e.CommandName = RadGrid.UpdateCommandName Or e.CommandName = RadGrid.PerformInsertCommandName Or e.CommandName = RadGrid.EditCommandName Then


        Dim editform As GridEditFormItem = DirectCast(DirectCast(e.Item, Telerik.Web.UI.GridDataItem).EditFormItem, GridEditFormItem)
        'Dim editform As GridEditableItem = CType(e.Item, GridEditableItem)


        Dim fvDateValidator As RangeValidator = CType(editform.FindControl("fvDateValidator"), RangeValidator)


        If fvDateValidator IsNot Nothing And iMaxEndDate <> "" And iMinStartDate <> "" Then
            fvDateValidator.Enabled = True
            fvDateValidator.Visible = True
            fvDateValidator.MinimumValue = iMinStartDate.ToShortDateString
            fvDateValidator.MaximumValue = iMaxEndDate.Date.ToShortDateString
        End If


    End If


End Sub

Hello,

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {



            if (e.Item is GridEditableItem && e.Item.IsInEditMode)
            {
                GridEditableItem item = e.Item as GridEditableItem;

                // access or set control's property here
                RadDatePicker claim_dateTextBox = item.FindControl("claim_dateTextBox") as RadDatePicker;
                RequiredFieldValidator fvDateRequiredFieldValidator = item.FindControl("fvDateRequiredFieldValidator") as RequiredFieldValidator;
            }
        }

Thanks,
