lorsque vous utilisez cette fonction et activer la pagination = true
private void BindGrid(string sqlQuery, ref GridView gv)
{
SqlConnection sqlConnection = null;
try
{
sqlConnection = new SqlConnection(strConnect);
SqlCommand scom = new SqlCommand(sqlQuery, sqlConnection);
scom.CommandTimeout = 100;
sqlConnection.Open();
SqlDataAdapter adapter = new SqlDataAdapter(scom);
DataTable dt = new DataTable();
adapter.Fill(dt);
gv.DataSource = dt;
gv.DataBind();
}
catch (Exception e)
{
Response.Write(e.Message);
}
finally
{
if (sqlConnection != null) sqlConnection.Close();
}
}
La solution
Ajouter un gestionnaire pour l'événement PageIndexChanging.
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
.....
.....
GridView1.DataSource=dt;
GridView1.DataBind();
}
Autres conseils
Essayez, ce code:
int newPagenumber = e.NewPageIndex;
GridView1.PageIndex = newPagenumber;
GridView1.DataSource = call the method that will fill ur dataset.
GridView1.DataBind();
