Hi,
I am using RAD Grid in sharepoint 2010. I have added the insercommand and when i click on save in the grid, i am getting "object reference not set to instance of object error".
Below is the code i have used:

<div>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1"></telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">

</telerik:RadAjaxLoadingPanel>

<telerik:RadGrid ID="RadGrid1" runat="server" EnableViewState="true" ShowStatusBar="true"

ShowFooter="True" onitemcommand="RadGrid1_ItemCommand"

ondeletecommand="RadGrid1_DeleteCommand"

oninsertcommand="RadGrid1_InsertCommand"

onupdatecommand="RadGrid1_UpdateCommand"

onneeddatasource="RadGrid1_NeedDataSource" >

<MasterTableView DataKeyNames="Title" 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("Title") %>' >

</telerik:RadTextBox>

</InsertItemTemplate>

<EditItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Eval("Title") %>' >

</telerik:RadTextBox>

</EditItemTemplate>

<ItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" ReadOnly="true" runat="server" Text='<%# Eval("Title") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<ClientSettings EnableRowHoverStyle="true">

</ClientSettings>

</telerik:RadGrid>

<asp:Button ID="btnSubmit" runat="server" Text="Submit"

onclick="btnSubmit_Click" />

</div>

protected void RadGrid1_InsertCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem item = e.Item as GridEditableItem;

Hashtable values = new Hashtable();

item.ExtractValues(values);

string ti = values["Title"].ToString();

}

In the Insercommand code, values is coming as null.
How to fix this?
Thanks

Hi,
I changed the code as you mentioned. I am getting the error as below:
"Unable to cast object of type 'Telerik.Web.UI.GridDataInsertItem' to type 'Telerik.Web.UI.GridEditFormInsertItem'."
Also, when i commented the below AJAX code, my earlier code is working and i am getting the values in InsertCommand. What needs to be changed in the below code.
