So, what is the issue here? I hope, GridView has data.

ID="GridView1" runat="server" AutoGenerateColumns="False" Visible="false"
DataSourceID="SqlDataSource1" >

ConnectionString="<%$ ConnectionStrings:peersConnectionString %>"

What are you doing inside the Page load Event?

Jeet Gupta 19-Jan-15 6:11am

first try to check whether the data is binding on the gridview or not. then use visible false option.

Member 11382784 19-Jan-15 6:11am

protected void Page_Load(object sender, EventArgs e)
{

}
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
if (CheckBox1.Checked)
{
GridView1.Visible = true;
}
}

check SELECT * FROM [pubs], any data is coming for not and also check those data is binding to the gridview or not.
first make the gridview visible =TRUE, then check the gridview binds with the data or not.

Member 11382784 19-Jan-15 7:10am

data is binding to gridview there is no problem

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 19-Jan-15 7:15am

Yes, Jeet is correct. First check if the GridView has data or not. Make it visible true and see if it is loading correctly or not.

you should handle the post back , on your page load you are biding again , which means refresh the grid view with default values then it will go to your button code , so the code of your page load will be :

C#

protected void Page_Load(object sender, EventArgs e)
{


 if (!IsPostBack)
    {
        // Validate initially to force asterisks
        // to appear before the first roundtrip.
       GridView1.DataBind();
    }
 

}
