Grid Selection, Changes when refresh data

[Bidin Dinesababu]

Hai,
I am using DataBoundGrid, and the contents gets refreshed each time I press a refresh button.
But the problem is, when I refresh the contents of the grid, the selection goes to the row just above the current selection. ( Selection shifts one row up each time I refresh the contents).
The grid is wired with Filter bar. I update the filterbar, each time I refresh data.

Is there any specific reason for this. Is there any means by which I can avoid the same..
THanks in advance,
Bidin

How are you refreshing the contents of the grid? Are you doing a DataSet.Merge, or changing values directly in the grid using an indexer on the grid, or changing values directly in your datatable, or set a new datasource to the grid, or something else?.

Can you post a little sample showing the problem? If not, can you post your code that you use to refresh the contents?

Here is the sample which I use to refresh the grid data within a class derived from DataBoundGrid.
_dataSet is a member variable. Which gets merged with the new data.

DataSet ds = _dataSet.Clone();
ds.ReadXml(new System.IO.StringReader((xmlData)));
_dataSet.Merge(ds, false, MissingSchemaAction.AddWithKey);
this.BeginUpdate();
this.FreezePainting = true;
this.DataSource = _dataSet.Tables["M"];
this.BringToFront();
this.FreezePainting = false;
this.EndUpdate();

I don''t really understand how the grid would play a role on how the data is merged into this data set. If you use the same code to update a Windows Forms DataGrid, does the data get positioned properly there?

You mentioned a FilterBar in your first post. You might consider unwiring and re-wiring the filterbar (while freezePainting is true) to see if that affects anything? Is there an active filter when this code is being hit?
