How to Hide Gridview and Show the selected gridview row details in Form View using ASP.NET C#

In this post I'm going to post details about how to hide full Gridview by selecting individual gridview row and show that gridview row details in Formview;

In this example, I'm using AdventureWorks Database and datebase table name HumanResources.Employee

Click here to Download AdventureWorks Database

Here I'll post the code and snapshot details

1. Design View

Add connection string code in web.config as below :

<connectionstrings>
 <add name="connection" connectionString="Data Source=localhost\sqlexpress;Initial   Catalog=AdventureWorks;Integrated Security=true;" providerName="System.Data.SqlClient"/>
</connectionStrings>

2.Design View's Source code in Default.aspx

                con.Close();
            con.Dispose();
        }
    }
    protected void Button3_Click(object sender, EventArgs e)
    {
        Button3.Text = "Back";
        GridView1.Visible = true;
        FormView1.Visible = false;

    }
}

4. Output: a) Gridview Shown

4 b) After clicking Full detail in First row in Gridview; Gridview has been hidden and showing Form view of the particular grid view rows full details
