Grabbing Data from a GridView on PostBack
Have you ever wanted to grab bulk data on a grid view? It's actually not that hard at all. Set the System.Web.UI.WebControls.GridView.DataKeys Property on the Grid, then on the postback event iterate over the grid like so.
1: foreach (GridViewRow row in gridView.Rows)
2: { 3: DataKey data = gridView.DataKeys[row.RowIndex];
4: int Id = (int)data.Values["Id"];
5: TextBox myControl = row.FindControl("mycontrol") as TextBox; 6: //do something with the data
7: }
And on your GridView add the DataKeys Property
1: <asp:GridView ID="myGrid" runat="server"
2: DataSourceID="myDataSource"
3: DataKeyNames="Id" >
