Hey,
I have some code in App_Code folder so it's accessible everywhere.
I need to use a DataTable in the like this as well, but when I try to add rows from the content page, I get Null Reference errors:
App_Code:
public DataTable dt;
private void Page_Load()
{
dt.Columns.Add(Col1, typeof(string));
dt.Columns.Add(Col2, typeof(string));
dt.Columns.Add(Col3, typeof(string));
}
Page:
dt.Rows.Add("val1", "val2", "val3");
dt.Rows.Add("val1", "val2", "val3");
dt.Rows.Add("val1", "val2", "val3");
dt.Rows.Add("val1", "val2", "val3");
dt.Rows.Add("val1", "val2", "val3");
If I change
public DataTable dt;
in App_Code to
public DataTable dt = new DataTable; ...
Go to the complete details ...
