I suggest that you add the onKeyUp property to the TextBox instead of Button. That way, the user will be able to view changes to label without clicking the submit button.

Try this.

XML

<asp:TextBox ID="TextBox1" runat="server" OnTextChanged="textboxchanged" AutoPostBack="true"></asp:TextBox>
  <asp:Label ID="lbl" runat="server" Text="No"></asp:Label>

C#

protected void textboxchanged(Object sender, EventArgs e)
 {
     if (TextBox1.Text != "")
     {
         lbl.Text = "Yes";
     }
     else { lbl.Text = "No"; }
 }

<asp:Label ID="lbl" runat="server" Text="No">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true" OnRowDataBound="CustomersGridView_RowDataBound" ShowFooter="true">
<columns>
<asp:BoundField DataField="amt" HeaderText="Amt"/>
<asp:TemplateField>
<footertemplate>
<asp:TextBox ID="TextBox1" runat="server" OnTextChanged="textboxchanged" AutoPostBack="true">

DataTable dt = new DataTable();
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
dt.Columns.Add("amt", typeof(Int32));
dt.Columns.Add("pamt", typeof(Int32));
dt.Columns.Add("damt", typeof(Int32));
DataRow dr=dt.NewRow();
dr[0] = 200;
dt.Rows.Add(dr);
DataRow dr1 = dt.NewRow();
dr1[0] = 400;
dt.Rows.Add(dr1);
GridView1.DataSource = dt;
GridView1.DataBind();
string directoryPath = @"D:\New folder";
TextBox TextBox1 = (TextBox)GridView1.FooterRow.Cells[0].FindControl("TextBox1");
TextBox1.Text = "abc";
}
}

protected void textboxchanged(Object sender, EventArgs e)

TextBox TextBox1 = (TextBox)GridView1.FooterRow.Cells[0].FindControl("TextBox1");
if (TextBox1.Text != "")
