Question

I have a gridview that is set up to do paging but it is not working correctly.

Only the first page’s control is visible – the other pages have boxes rendered but no control inside them.

Does anyone know why this may be? I have checked that I have more than one page of data.

Thanks,

Oliver

I have attached a screenshot which I hope illustrates my problem.

EDIT: source for the gridview

    <asp:GridView ID="GridView1" runat="server" OnPageIndexChanging="GridView1_PageIndexChanging" 
    CssClass="GridView1" OnSelectedIndexChanged="GridView_SelectedIndexChanged"
    AllowPaging="True" PageSize="20">      
    <selectedrowstyle backcolor="LightCyan" forecolor="DarkBlue" font-bold="true" />
</asp:GridView>

it is populated using a dataset generated in c#

EDIT: c# codebehind

    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView1.PageIndex = e.NewPageIndex;
        bindGridView();
    }

    public void bindGridView()
    {
        //declare the connection string to use
        string connectionString = ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

        //create sql connection
        SqlConnection mySQLconnection = new SqlConnection(connectionString);

        //open connection
        mySQLconnection.Open();

            //define command using text string
            SqlCommand mySqlCommand = new SqlCommand(sqlTester, mySQLconnection);
            SqlDataAdapter mySqlAdapter = new SqlDataAdapter(mySqlCommand);

            //create dataset to fill gridview with
            DataSet myDataSet = new DataSet();
            mySqlAdapter.Fill(myDataSet);

            //fill gridview
            GridView1.DataSource = myDataSet;
            GridView1.DataBind();

        //close the sql connection
        mySQLconnection.Close();
    }

I think according to your aspx and your .cs. there is some problem in your css file”GridView1“.Try to remove the css class and tell us . is the problem still exist or not.

Note:

It’s not related to your question. but i think you should separate your code in layers instead of writing all the code in your page code behind.
