Hi,
I have used the following namespace in my project.
using Telerik.Web.UI.GridExcelBuilder;
using xls = Telerik.Web.UI.ExportInfrastructure;
But it shows type are namespce ExportInfrastructure doesnt exist in the Telerik.Web.UI namespace.I have to add any reference in bin folder?

1. When running the example with multiple outstanding Add or Update forms, clicking on either the insert or update link will validate all the forms as shown in the attached MultipleOpenForm.png. Is there a way to prevent the validation of all outstanding forms and only restrict validation to the form where user click insert or update link? I tried to use validation group but could not find a way to link it to the insert or update link. Would greatly appreciate it if you can show me an example of how to do that for the RadGrid
2. In order to prevent outstanding multiple forms open at the same time, I have added the following code to reset all outstanding edit form as shown below:
   protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

   {

       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)

       {

           //Clear and reset all outstanding edit form

           e.Item.OwnerTableView.IsItemInserted = false;

           e.Item.OwnerTableView.ClearEditItems();

           e.Item.OwnerTableView.ClearChildEditItems();
   Add these codes will close all outstanding forms and will only allow one form open at a given time. Unfortunately, user will no longer able to insert or update an item when clicking on the insert or update link. The form will close without calling the Insert or Update events as well as other events defined in the RadGrid as shown below:
   <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" OnNeedDataSource="RadGrid1_NeedDataSource"

       OnDetailTableDataBind="RadGrid1_DetailTableDataBind" OnInsertCommand="RadGrid1_InsertCommand"

       OnUpdateCommand="RadGrid1_UpdateCommand" OnDeleteCommand="RadGrid1_DeleteCommand"

       OnEditCommand="RadGrid1_EditCommand" OnItemCreated="RadGrid1_ItemCreated" OnItemDataBound="RadGrid1_ItemDataBound"

       OnItemCommand="RadGrid1_ItemCommand">
   Only the delete event work. I searched the entire forum but did not find a solution to this problem. Can you please help to resolve this problem. It is a show stopper for us.
3. The Date (Birth Date) RequiredField validation does not work for the DetailTable GridTableView even though it is exactly the same as the Parent Birth Date (see MultipleOpenForm.png). Can you tell me what wrong with the Child Date?
   <DetailTables>

        <telerik:GridTableView DataKeyNames="ID,DependentTobaccoUsage,DependentWellnessFactor"

            Name="Child" CommandItemDisplay="Top" CommandItemSettings-AddNewRecordText="Add new dependent">

            <Columns>

                <telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID" ReadOnly="true"

                    Visible="false">

                </telerik:GridBoundColumn>

                <telerik:GridDateTimeColumn DataField="DependentDOB" HeaderText="Birth Date<span style='color:#CD4800'>*</span>"

                    SortExpression="DependentDOB" UniqueName="DependentDOB" DataFormatString="{0:MM/dd/yyyy}"

                    HeaderStyle-CssClass="bold" ColumnValidationSettings-EnableRequiredFieldValidation="True">

                    <ColumnValidationSettings EnableRequiredFieldValidation="true" RequiredFieldValidator-Display="Dynamic">

                        <RequiredFieldValidator ForeColor="Red" Text="*This field is required">

                        </RequiredFieldValidator>

                    </ColumnValidationSettings>

                </telerik:GridDateTimeColumn>
