i wrote code like that
SqlConnection con = new SqlConnection(ConfigurationSettings.AppSettings.Get("Constring1"));
string name = string.Empty;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GetGridValues();
}
}
protected void GetGridValues()
{
con.Open();
string str = "select empid,emp_name,depid from employee";
SqlCommand cmd = new SqlCommand(str, con);
SqlDataReader dr = cmd.ExecuteReader();
GridView1.DataSource = dr;
GridView1.DataBind();
con.Close();
}
but , i got this error.
The data source does not support server-side data paging.

Hi,
You used this way
protected void GetGridValues()
{
con.Open();
string str = "select empid,emp_name,depid from employee";
SqlCommand cmd = new SqlCommand(str, con);
DataSet ds = cmd.ExecuteReader();
GridView1.DataSource = ds;
GridView1.DataBind();
con.Close();
}
here for binding any data bind control you used dataset or datatable not datareader

You have made the mistake-the datasource is an "OdbcDataReader" and a Reader don't support paging.
Fill first a DataSet or DataTable and bind it then as DataSource
then paging will work out
protected void GetGridValues()
{
con.Open();
string str = "select empid,emp_name,depid from employee";
SqlCommand cmd = new SqlCommand(str, con);
DataSet resultDs = new DataSet();
SqlDataAdapter dataAdapter = null;
dataAdapter = new SqlDataAdapter(str , con);
dataAdapter.Fill(resultDs);
GridView1.DataSource = resultDs;
GridView1.DataBind();
con.Close();
}
Now will work
