soft save the inserted grid values to datatable

[Venkatesh]

HI,
I am binding the radgrid using the session variable. The session variable is getting data from a datatable.

Session["GridData"] = datatablevalue ;
 RadGrid1.DataSource = Session["GridData"];

In the insertcommand, i want to insert the new values to the existing session variable.

How to achieve this?
Thanks

Thanks Antonio for the reply.
Before i open up the formal ticket, i would need to make sure the below.

When the page loads, the grid is empty. I am binding the gridtemplate as below:

<telerik:RadGrid ID="RadGrid1" runat="server"  EnableViewState="true"
        ShowFooter="True" Oninsertcommand="RadGrid1_InsertCommand"
        onneeddatasource="RadGrid1_NeedDataSource" >
    <MasterTableView DataKeyNames="ProductNumber" AutoGenerateColumns="false" EditMode="InPlace" CommandItemDisplay="TopAndBottom" CommandItemSettings-AddNewRecordText="Add New Item" >

                    <Columns>
                     <telerik:GridEditCommandColumn ButtonType="ImageButton">
                        </telerik:GridEditCommandColumn>
                        <telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"
                            ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" ConfirmDialogHeight="100px"
                            ConfirmDialogWidth="220px">
                        </telerik:GridButtonColumn>

<telerik:GridTemplateColumn DataField="Title" HeaderText="Product Number" UniqueName="ProductNumber"
                            Visible="true">
                      <InsertItemTemplate>
<telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Bind("ProductNumber") %>' >
                                </telerik:RadTextBox>
                            </InsertItemTemplate>
                            <EditItemTemplate>
 <telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Eval("ProductNumber") %>' >
                                </telerik:RadTextBox>
                            </EditItemTemplate>
                            <ItemTemplate>
<telerik:RadTextBox ID="RadtxtPrdNumber" ReadOnly="true" runat="server" Text='<%# Eval("ProductNumber") %>' />
                            </ItemTemplate>
                        </telerik:GridTemplateColumn>
</Columns>

    </MasterTableView>
     <ClientSettings EnableRowHoverStyle="true">
        </ClientSettings>

    </telerik:RadGrid>

When no items are available in the grid, i am getting object reference error. In the inserttemplate if i remove the "Bind" code, the object reference error disappers, however i am not able to retrieve the inserted value.

How to fix this?

Hi,

You can set the text in ItemDataBound event as shown below.
C#:

protected void RadGrid2_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridDataInsertItem && e.Item.OwnerTableView.IsItemInserted)
    {
        GridDataInsertItem item = (GridDataInsertItem)e.Item;
        RadTextBox txt = (RadTextBox)item.FindControl("RadtxtPrdNumber");
        txt.Text="text";
    }
}

Thanks,
Shinu.
