Determine visible row # in winforms datagrid?

How can I tell which rows are visible in a datagrid (winforms app)? I
have alot of data in the grid (bound to a datatable), and I need to
refresh that data frequently. (theres no easy way to know what data
has changed), so Im looking at just updating the visible portion of the
grid if this is possible.

Ah found my own answer:

int firstVisibleRow =
dataGrid1.HitTe st(dataGrid1.Pr eferredRowHeigh t+10,dataGrid1. RowHeaderWidth+ 10).Row;
int lastVisibleRow = firstVisibleRow + dataGrid1.Visib leRowCount;

I might be blind, but I cannot find a way to ensure that a particular row in my data grid is visible i.e the grid is scrolled so that the row at the current position of the currency manager is contained within the client rectangle. In fact just having the scrollbars default to being scrolled to the bottom would do. directly influencing the value of the Datagrid's scroll bars has no effect. I want something equivilent to the...

Hey all, I have contusions and I think a minor concussion after trying to find information on advanced WinForms DataGrid use. Does anyone know of a site / book that gets really in-depth on the DataGrid? I've found a number of postings and help topics but would like to find something that treats the DataGrid as a topic, not just a loose collection of hundreds of articles. TIA,

I am just getting into the WinForms data grid, and just about everything I am seeing on it seems to say that the grid must be bound to an ADO.Net dataset. I want to use the grid as a simple unbound grid-- all I want to do is write to the grid, read from it, and allow the user to enter text in particular cells. Is the WinForms datagrid a viable candidate for this sort of work? If it is, can you recommend a resource to help me get up to...

Win2000 ..Net 1.1 SP1 c# using Visual Studio Ok, I'm currently in a "knock down - drag out" tussle with the .Net 1.1 datagrid.

By selected row I mean the row

I have a datagrid that I want to add a new column to. This column will only be visible under certain conditions. So I want to set the column visible=false. Then when the right condition happens to change it to visible=true. You can't do that with a bound column (no ID), but you can create a templatecolumn with a label. To make these visible, I am going through each datagriditem and making them visible after I have bound the data to...

Hi, I've a DataGrid and a DataSet (not a DataView) as the DataSource. Users can click on column headers and sort the contents of the DataGrid. I want to know how to determine which column is being used to order the sorted data. I can't see in the microsoft DataGrid in vb.net the Event 'SortCommand'. I think that its because I'm using vb.net not asp. Thanks in advance.

(one of our developers posted this and it got no answer so I'm giving it another try) I'm converting a DataGrid utility component that previously used the columns array to function as it has in the past without using the columns array. The reason for this is because it must process columns created at run time which does not create entries in the columns array..... My problem is that if datagrid columns created at design time are...
