How to determine when selected rows in a datagrid have changed ???

[BBFrost]

Ok, I know how to count the number of selected datagrid rows using the code
below. What has me stumped is how to determine when the selected rows
within a datagrid have been changed. The DataGrid object doesn't seem to
have a any type of a selection changed type of event I can grab.

THE QUESTION: Does anyone know how to determine when the selected row or
set of rows within a datagrid has changed ???

This is driving me nuts !

Thanks in advance!

[this.dgSearchResults.DataSource,
this.dgSearchResults.DataMember];

DataView dv = (DataView)cm.List;

int iRowCount = 0;

for(int i=0; i < dv.Count; ++i)
{
if(this.dgSearchResults.IsSelected()){ ++ iRowCount;}
}
}

Hi,
The (corresponding) underlying datarow of the bound datasource will have the
RowState property. This property tells you if that particular row has been
modified

Rajesh,

Thanks for the response. Its very much appreciated. Unfortunately after
re-reading the question I posed I realized that the question was not well
formed.

What I'm trying to figure out is the following ...

Rows 12 thru 24 are selected in a datagrid. How do I tell when the user
selects rows 45 thru 70 ???

Guess I'd better repost with a more properly formed question. :)

Thanks for taking the time to answer.

Best wishes,
