Where is HitTestInfo?

[Brett Romero]

I've read on the forums of other people having problems with
HitTestInfo not appearing. I've read these but they didn't help:

System.Windows. Forms.DataGrid doesn't have it either. Any ideas?

Thanks,
Brett

Brett,

When you open project in VSS it should create two subfolders - 'bin' and
'obj'. Both folders have subfolders in their own - Debug and Release.

Look at
[project folder]\obj\Debug
and
[project folder]obj\Release

there have to be files with extension 'projdata', delete them

Or, easier, delete the whole 'obj' folder all together; VS will create it
again

Sorry, didn't mean to offend. Guess I didn't understand the problem
enough and was posting gibberish. Not trying to claim I know more than
you. I appreciate all of your help greatly.

I did also get it to work by just typing HitTestInfo. All of the weird
compile errors went away. Not sure why. I also had to manually type
hit.Row or hit.Column. No intellisense. It is all working now.

I didn't find a *.projdata file. I'm using VSS with VS.NET so not sure
if that changes things. I do have these files:
*.csproj
*.scc
*.sln
*.csproj.user
*.suo
*.csproj.vspscc

That tip on deleting the file and getting intellisense back would be
great. Any idea why our setups are different in reference to
*.projdata?

Here's the code that will get the coordinates of a cell in a datagrid.
Also highlights the clicked row and dehighlights when a new row is
clicked. One thing, how do I get the value in say column 2 when all I
have are coordinates? I can't use CurrentCell or EditCell. I'm using
the right mouse click so there is no EditCell. CurrentCell gives a
cell from left clicking. I just need something I can feed in my row
index, traverse to a column and get that value.

private int lastRowSelected = 0;
private void Participant_Mou seDown(object sender, MouseEventArgs e)
{
//Participant is the datagrid name
Participant.UnS elect(lastRowSe lected);

Point pt = new Point(e.X, e.Y);
System.Windows. Forms.DataGrid. HitTestInfo hit =
Participant.Hit Test(pt);
if (e.Button == MouseButtons.Ri ght)
{
if(hit.Type == DataGrid.HitTes tType.Cell)
{
Participant.Sel ect(hit.Row);
lastRowSelected = hit.Row;
}
}
}

Thanks agian,
Brett

Ok, I tried that but HitTestInfo still doesn't show up. Deleted both
the bin and obj folders then rebuilt.

Any ideas on getting a datagrid cell value using coordinates?

Thanks,
Brett

Other than HitTest method? ...Hm I can't think of anything. DataGrid.HitTes t
is meant to be used for this.

Sorry to hear deleting those files/folders didn't work for you, they
certainly did work for me.

Here's a revised "if" statement that does get the cell value:

if(hit.Type == DataGrid.HitTes tType.Cell)
{
Participant.Sel ect(hit.Row);
DataGridCell dgc = Participant.Cur rentCell;
dgc.RowNumber = hit.Row;
dgc.ColumnNumbe r = 2;
Participant.Cur rentCell = dgc;
personIDToFile = Participant[dgc].ToString();
//save current cell for dehighlighting on next selection
lastRowSelected = hit.Row;
}

Another question on this, how do I handle some one highlighting a cell,
holding down shift and selecting three rows. I'd like to get the value
from column three for each of those rows (as I do above). My current
method will always get the value from the cell where the right mouse
click occurred. Any ideas?

Thanks,
Brett

Brett,

I can see that similar questions has been asked many times in the news
groups. I believe that you can find the answer of your question in google.
For example look at this thread
