Hello Jocelyn,

you can get "e.Item.DataItem" only in itemDataBound event.

for update please check below code snippet.

<MasterTableView DataKeyNames="ID">

<Columns>

<telerik:GridBoundColumn DataField="ID" HeaderText="ID" UniqueName="ID">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn UniqueName="Name">

<ItemTemplate>

<asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>'></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<asp:TextBox ID="txtName" runat="server" Text='<%# Eval("Name") %>'></asp:TextBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridEditCommandColumn>

</telerik:GridEditCommandColumn>

</Columns>

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem item = e.Item as GridEditableItem;

// get primary key value

string str1 = item.GetDataKeyValue("ID").ToString();

// get bound column

string str2 = (item["ID"].Controls[0] as TextBox).Text;

// get control from template column

string str3 = (item.FindControl("txtName") as TextBox).Text;

}

Thanks,

My Grid DataSource is a DataTable. I am trying to update things like the Demo, But when I try it I just don't update.. But I need to validate the row before updating, so i would like to be able to access to the modified row and valide it.

Here some code:

<div class="fullscreen">

                <telerik:RadGrid ID="gridAllergies" runat="server"

                    Width="100%" Skin="WebBlue" style="border:0;outline:none" Height="80%" CellSpacing="0"

                    GridLines="None">

                    <MasterTableView >

                        <CommandItemSettings ExportToPdfText="Export to PDF"></CommandItemSettings>

                        <RowIndicatorColumn Visible="True" FilterControlAltText="Filter RowIndicator column"></RowIndicatorColumn>

                        <ExpandCollapseColumn Visible="True" FilterControlAltText="Filter ExpandColumn column"></ExpandCollapseColumn>

                        <Columns>

                            <telerik:GridEditCommandColumn FilterControlAltText="Filter EditCommandColumn column"

                                ButtonType="PushButton" EditText="Modifier" Resizable="False">

                                <HeaderStyle Width="75px" />

                            </telerik:GridEditCommandColumn>

        item.UpdateValues(allergie)

    End Sub

I think I wasn't clear in my first post, because I don't understand your post Jayesh.
