Hi akhter,

Refer below sample.


Name : <asp:TextBox runat="server" ID="txtName" AutoPostBack="true" OnTextChanged="Save" />



protected void Save(object sender, EventArgs e)
    ScriptManager.RegisterStartupScript(this, this.GetType(), "", "alert('" + txtName.Text + "');", true);


Protected Sub Save(ByVal sender As Object, ByVal e As EventArgs)
    ScriptManager.RegisterStartupScript(Me, Me.GetType(), "", "alert('" & txtName.Text & "');", True)
End Sub
