I'm having problems with the DataGrid

I'm working on a program that will display a modal form containing 2
datagrids (but might as well focus on just one for now). These
datagrids display read-only information that is stored in arrays.

I'm completely new to datagrids, so I don't know what I am doing wrong
as I'm getting runtime errors. Please help


namespace ZZZ
{
............
public struct ProViewStr
{
public string[] LineNameArr;
public int[] LineStatusArr;
..................
}
........
public class ProForm : System.Windows.Forms.Form
{
.......
protected ProViewStr proViewStr;
.......
.......
private void menu_DataInfo_Click(object
sender,System.EventArgs e)
{
DataInfo dataInfo = new DataInfo();
int L = proViewStr.LineStatusArr.Length;
string[] Lname = proViewStr.LineNameArr;

dataInfo.DatSetup(proViewStr);
dataInfo.PopulateSurveyLineGrid();

dataInfo.ShowDialog();
}
} //end of class
}//end of namepace

myRow["Line Name"] =

dt.Rows.Add(myRow);

Hi:

Please post the errors. If is difficult to figure out what's going on
without the benefit of compiler output.

I am getting:

An unhandled exception of type 'System.ArgumentException' occurred in
system.data.dll

Additional information: Column 'Line Name' does not belong to table
SurveyLineGrid.

Basically the reason I posted is because I am completely lost with
DataGrids. And I was wondering if the code above is correct. If
there is something missing or something I did not include.
Am I by chance supposed to put something in under the 'TableStyles
(Collections)' property for the DataGrid
along with my code ?

I really need to get this working. I've looked through a few different
C# text books, MSDN library, and the like but I still can't figure out
how to apply -- what is mostly shown as coding for database
applications, to a simple DataGrid with information stored in
arrays.

Please help.
