this is .aspx code

ASP.NET

<asp:GridView ID="GridView2" runat="server" GridLines="None" 
                onrowdatabound="GridView2_RowDataBound" align="center"  
                AllowPaging="True" PageSize="3" 

                
                
                onpageindexchanging="GridView2_PageIndexChanging" AllowSorting="True" >
                
                <AlternatingRowStyle BackColor="White" />
                <RowStyle BackColor="#CCCCCC" />
                
            </asp:GridView>

this is binding data code in C#

C#

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
               
                Recentinternship();
                
            }



        }
        protected void Recentinternship()
        {
            SqlConnection con = new SqlConnection("Data Source=jayraj-pc\\sqlexpress;Initial Catalog=Internship;Integrated Security=True;Pooling=False");
            con.Open();
            string str = "select B.CompanyLogo as ' ',A.Title,A.InternshipStartDate,A.ApplicationDeadline,A.Duration,A.InternshipCity,A.Category,A.Stipend,A.InternshipID,A.Degree,A.Branch,A.CompanyID,A.Title,A.CompanyName from Internship AS A INNER JOIN  Companies AS B ON A.CompanyID=B.CompanyID ";
            SqlCommand cmd = new SqlCommand(str, con);
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            SqlDataReader dr = cmd.ExecuteReader();

            GridView2.DataSource = dr;
            GridView2.DataBind();
            //GridView2.BottomPagerRow.Visible = true;


            dr.Close();

            con.Close();

        }
 protected void GridView2_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            GridView2.PageIndex = e.NewPageIndex;
            Recentinternship();
        }

You have to change Source page code here..
onpageindexchanging = "GridView2_PageIndexChanging" to
OnPageIndexChanging = "GridView2_PageIndexChanging"

C#

protected void Recentinternship()
        {
            SqlConnection con = new SqlConnection("Data Source=jayraj-pc\\sqlexpress;Initial Catalog=Internship;Integrated Security=True;Pooling=False");
            con.Open();
            string str = "select B.CompanyLogo as ' ',A.Title,A.InternshipStartDate,A.ApplicationDeadline,A.Duration,A.InternshipCity,A.Category,A.Stipend,A.InternshipID,A.Degree,A.Branch,A.CompanyID,A.Title,A.CompanyName from Internship AS A INNER JOIN  Companies AS B ON A.CompanyID=B.CompanyID ";
           // SqlCommand cmd = new SqlCommand(str, con);
            SqlDataAdapter da = new SqlDataAdapter(str,con);
            DataSet ds = new DataSet();
            da.fill(ds,"0");
            
          //  SqlDataReader dr = cmd.ExecuteReader();
 
            GridView2.DataSource = ds.Tables["0"].ToString();
            GridView2.DataBind();
            //GridView2.BottomPagerRow.Visible = true;

 
            dr.Close();
 
            con.Close();
 
        }

Solution 3

Use Dataset/Datatable for binding with gridview.

DataReader doesn't allow paging because its forward only

protected void Recentinternship()
{
SqlConnection con = new SqlConnection("Data Source=jayraj-pc\\sqlexpress;Initial Catalog=Internship;Integrated Security=True;Pooling=False");
con.Open();
string str = "select B.CompanyLogo as ' ',A.Title,A.InternshipStartDate,A.ApplicationDeadline,A.Duration,A.InternshipCity,A.Category,A.Stipend,A.InternshipID,A.Degree,A.Branch,A.CompanyID,A.Title,A.CompanyName from Internship AS A INNER JOIN Companies AS B ON B.CompanyID=A.CompanyID ";
DataTable dt = new DataTable();
SqlCommand cmd = new SqlCommand(str, con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
//SqlDataReader dr = cmd.ExecuteReader();
da.Fill(dt);
if (dt.Rows.Count > 0)
{

GridView2.DataSource = dt;
GridView2.DataBind();
}
//GridView2.BottomPagerRow.Visible = true;

con.Close();

}

I changed code to like this but the problem i am getting is no data is loding in gridview.

Tom Marvolo Riddle 15-Apr-14 2:51am

check whether the query is returning values or not

jayraj86 15-Apr-14 3:39am

yes its returning

Tom Marvolo Riddle 15-Apr-14 3:50am

put a breakpoint here: GridView2.DataSource = dt; and view it in Quickwatch

If dt has values then gridview must show the value(returning column name must match with gridview row name)

Solution 4

write OnPageIndexChanging instead of onpageindexchanging..and use dataset and datatable for gridview binding..

XML

<asp:GridView ID="GridView2" runat="server" GridLines="None"
                onrowdatabound="GridView2_RowDataBound" align="center"
                AllowPaging="True" PageSize="3"



                 OnPageIndexChanging="GridView2_PageIndexChanging" AllowSorting="True" >

                <AlternatingRowStyle BackColor="White" />
                <RowStyle BackColor="#CCCCCC" />

            </asp:GridView>
