Hi Peter,

Do you mean that your DataGridView is binding to a DataSet and you need to
find in the DataSet values?

If so, you can use DataTable.Select method to find the rows that meet your
criteria. Please check the following link for more information.

I can find the row, but how do I make the row that contains the search value
visible in the DataGridView if the DataGridView displays only 20 records at
a time and the search record is the 100th record?
 
Hi Peter,

Are you using a DataView as the data source of the DataGridView? If so, we
cannot make it visible unless the row meets the criteria of the filter.

I do have a criteria filter which does find the desiried row, but the row
never becomes visible in the grid if it's not visible when the search
started. How do I make the row visible in the DataGridView after I find the
row in the DataView?

System.Data.DataView dvOpenOrders;
.....
.....
this.dvOrders.Table = dt.GetOrders();
this.dataGridView1.DataSource = this.dvOpenOrders.Table;

this.dvOrders.Sort = "id";
object[] findKey = new object[1];
DataColumn[] dcolPk = new DataColumn[1];
dcolPk[0] = tbl.Columns["id"];
tbl.PrimaryKey = dcolPk;
tbl.DefaultView.Sort = "id";
findKey[0] = id;
row = tbl.DefaultView.Find(findKey);
 
Hi Peter,

Do you mean that before searching, the row is not visible. And after
searching, you need to make the row visible? If so, we can only make it
visible when the row meets the criteria of the DataView. If you need help
on how to make it meet the criteria, please provide the code you're using
to set the criteria.

Yes, before searching, the row is not visible and after searching I need to
make the row visible

The following code finds the row but does not make it visible.

System.Data.DataView dvOpenOrders;
.....
.....
this.dvOrders.Table = dt.GetOrders();
this.dataGridView1.DataSource = this.dvOpenOrders.Table;

this.dvOrders.Sort = "id";
object[] findKey = new object[1];
DataColumn[] dcolPk = new DataColumn[1];
dcolPk[0] = tbl.Columns["id"];
tbl.PrimaryKey = dcolPk;
tbl.DefaultView.Sort = "id";
findKey[0] = id;
row = tbl.DefaultView.Find(findKey);
 
Hi Peter,

I don't quite understand your code, because you're setting a DataTable as
the DataSource and what's dvOpenOrders? What is the default view for tbl?

As I mentioned in my last post. If you can use Find to find the row in a
DataView, it must be visible before and after it is found. If a row is
filtered out by the DataView, it you are not able to display it, unless you
change the filter criteria or change value of the row.
