Thanks for the response, Maria. Sure, I have included the code for ajaxifying the problematic fields. Please help.

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="GridView1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="GridView1" />

<telerik:AjaxUpdatedControl ControlID="TextBox" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<div>

<asp:TextBox ID="TextBox1" runat="server" Width="400px" Text="not updated"></asp:TextBox>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"

SelectCommand="SELECT [CustomerID], [CompanyName], [ContactName] FROM [Customers]">

</asp:SqlDataSource>

<asp:GridView ID="GridView1" DataSourceID="SqlDataSource1" AllowPaging="True" runat="server"

OnRowCommand="GridView1_RowCommand" OnRowCreated="GridView1_RowCreated">

<Columns>

<asp:TemplateField HeaderText="TemplateField">

<ItemTemplate>

<asp:ImageButton ID="ImageButton1" CommandName="MyCommand" CommandArgument='<%# Eval("CustomerID") %>'

ImageUrl="~/images/arrow.gif" runat="server" />

</ItemTemplate>

</asp:TemplateField>

<asp:ButtonField ButtonType="Button" HeaderText="ButtonField" CommandName="Test"

Text="Button" ImageUrl="~/images/arrow.gif" />

</Columns>

</asp:GridView>

</div>

protected void GridView1_RowCreated(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)

{

if (e.Row.RowType == DataControlRowType.DataRow)

{

e.Row.PreRender += new System.EventHandler(Row_PreRender);

}

protected void GridView1_RowCommand(object sender, System.Web.UI.WebControls.GridViewCommandEventArgs e)

{

TextBox1.Text = string.Format("CommandName:{0}, CommandArgument:{1}", e.CommandName, e.CommandArgument);

}

protected void Row_PreRender(object sender, System.EventArgs e)

{

ImageButton ImageButton1 = ((ImageButton)(((Control)(sender)).FindControl("ImageButton1")));// error: imagebutton was null

RadAjaxManager1.AjaxSettings.AddAjaxSetting(ImageButton1, TextBox1);

}
