Even if GridView.DataKeyNames is set, Gridview.DataKeys[] is still empty
- by JustTryingToLearn
hi
GridView.DataKeynames stores the names of the primary key fields for the items displayed in a GridView control.
1) Even though I’ve set DataKeyNames, GridView still doesn’t store record’s primary key value(s) in DataKey object:
protected void SqlDataSource1_Selected(object sender,
SqlDataSourceStatusEventArgs e)
{
Label2.Text = GridView2.DataKeys[0].Value.ToString();//exception
}
Why not?
2) I assume when DataKeyNames is set, DataKey object stores both original and new values of a primary key ( assuming we issued an update command ) and when the update is finished, DataKey object discards the original value(s)?
Thank you
