Strange Rows.InsertAt behavior

[JasonDBurke]

Hello,
I'm attempting to insert new row data into a DataTable using the InsertAt method. What I want to do is have the new rows always appear first in the datagrid. When I stick this code behind a button and click repeatedly it works, however when I have this same code in a thread it does not insert correctly - it appends. Does it have anything to do with after the button click event is resolved somehow the datagrid is being reset as opposed to the code being in a thread? Below is the code.


DataRow myDataRow = myDataTable.NewRow();

myDataRow["Alert"] = "alert";

myDataTable.Rows.InsertAt(myDataRow,0);

dataGrid1.DataSource = myDataTable;

Thanks,
Jason

check on that last message..

That code is actually always appending. Even with a button click so there must be something I'm missing.

This code works..notice the AcceptChanges().. <-- that did it

DataRow myDataRow = myDataTable.NewRow();

myDataRow["Alert"] = "alert" + System.DateTime.Now.ToString();

myDataSet.Tables[0].Rows.InsertAt(myDataRow,0);

myDataSet.Tables[0].AcceptChanges();

dataGrid1.DataSource = myDataSet.Tables[0].DefaultView;
