You can Use WebMethod for the same. "http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type= "text/javascript" > "text/javascript" > function StoreProgress() { $.ajax({ type: "POST" , url: "NewVideosPage.aspx/storeprogress" , data: '{}' , contentType: "application/json; charset=utf-8" , dataType: "json" , success: OnSuccess, failure: function (response) { alert(response.d); } }); } function OnSuccess(response) { alert(response.d); } [System.Web.Services.WebMethod] public static void storeprogress() { con.Open(); cmd.CommandText = "update mytable set Progress='" + progress + "' where [Registered]='" +DropDownList1.SelectedValue.ToString() + "'and [EmployeID]='" + Label1.Text.ToString() + "' " ; cmd.Connection = con; cmd.ExecuteNonQuery(); con.Close(); }

Let's see with an example: in JavaScript: document.getElementById( "btnSample" ).click(); Server side control: "server" ID= "btnSample" Text= "" style= "display:none;" OnClick= "btnSample_Click" /> C# protected void btnSample_Click( object sender, EventArgs e) { con.Open(); cmd.CommandText = "update mytable set Progress='" + progress + "' where [Registered]='" +DropDownList1.SelectedValue.ToString() + "'and [EmployeID]='" + Label1.Text.ToString() + "' " ; cmd.Connection = con; cmd.ExecuteNonQuery(); con.Close(); }
