Hi,

Please try the following code snippet to show a message in the label when the Textbox value is '12'.I guess both the Label and the TextBox are in EditItemTemplate of GridTemplateColumn.

C#:

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem edit = (GridEditableItem)e.Item;
        TextBox txt = (TextBox)edit.FindControl("TextBox1");
        txt.AutoPostBack = true;
        txt.TextChanged += new EventHandler(txt_TextChanged);
    }
}
void txt_TextChanged(object sender, EventArgs e)
{
    TextBox txt = (TextBox)sender;
    GridEditableItem edit=(GridEditableItem)txt.NamingContainer;
    if (txt.Text == "12")
    {
        Label lbl = (Label)edit.FindControl("Label1");
        lbl.Text = "your text";
    }
}

Thanks,
Shinu.
