Open a New Window from GridView Using only JavaScript

A GridView control is good way to display data in a tabular format using its rich features and functions. We can display an entire database table on the browser using the GridView. Later we can manipulate the data using various GridView functions.

However, sometimes we need to show a pop-up window from a GridView by the click of a button. The new window can display corresponding (related) data, extracted from either a different database table or the same table.

Scenario

In our demo we'll use two database tables namely Employee and Employee Details, which will be binded with a Gridview.

Clicking the Employee Name (Pic. Column in Yellow) in the GridView will open another window with more details about the employee.

Showing Popup Window from GridView

The Markup with the GridView

We will add a GridView control with three columns as shown in the above picture. One of the columns (Employee Name) will have a button and the click event will open a new window showing miscellaneous details of the employee.

Code Behind default page (C#)

We shall now populate the GridView control, from Code Behind, with employee details like EmpID, Employee Name and Designation. The first block is written in C# and followed by VB.

            using (SqlConnection con = new SqlConnection("Data Source=DNA;"+

                "Initial Catalog=DNA_CLASSIFIED;User Id=sa;Password=demo;"+
                "Connect Timeout=30;"))
            {

                string strQuery = "SELECT *FROM dbo.Employee";

                    GridView.DataSource = dt;
                    GridView.DataBind();
                }
            }

Pop-up

Now, let us design the pop-up page. This page, as we said will display corresponding details for the Employee Name, which the user has selected on the parent (default) page.

The Mark Up of Pop-up Window Showing Employee Details

We will add few label’s on this page, which will display the details. The page_load event of this form, will take a value (EmpID) in the form of a QueryString (passed by the parent page), to extract other related details from another database table, called the “dbo.EmployeeDetails”.

    <form id="form1" runat="server">
