Hi,
I'm trying detect an empty cell in a datagrid when the content is posted
back to the server.
My code is...
Dim vDgi_GridItem As DataGridItem
For Each vDgi_GridItem In oASP_Dgd_Recept ions.Items
Response.Write( CType( vDgi_GridItem.C ells(10).Text.t rim.length ,
string) )
If vDgi_GridItem.C ells(10).Text.t rim.length > 0 then
...OK...
Else
...Not OK...
End If
Next
When the cell contains text, the length works fine, but if the cell is empty
(bound to a field with an empty string) it always returns a length of 6
characters.
Any ideas why ?? Why is the "trim" not emptying these space or whatever is
in there.
Regards

6 characters is the length of string " " (non-breaking space}. That it
what datagrids have in empty cells.Check cell text on this value to see if
it is empty.

Fantastic you got it !!!
If I test the content of the Cell with ... If vDgi_GridItem.C ells(10).Text =
" " it returns true. I was trying to show the content of the text but
of course it was rendering as HTML and so not showing.
I did read somewhere about the NULLTEXT property of datacloumn, that I may
be able to control what it does with Null values when showinng in data
grids.

Don't bother. Even if you set in your code empty string values to "", they
will be still fitted with " ".

Hi all...
I have a DataGrid bound to a DataTable. My DataTable gets updated
programmatically as it contains the status of a number of worker threads.
Each "main" worker thread launches a number "child" threads, so displaying
the status of these in a DataGrid is ideal - one row for each "main" thread,
one column for each "child" thread.
However, some of these threads take a while to update their status, so I'd

Hi - I have a datagrid that has a black header and the rows alternate
white and gray. The problem is that until items are added to the grid,
the grid appears as a large black rectangle, which is quite ugly. The
black area is larger then it is once an item is added. How can I solve
this problem either by:
A) Having only the header black and the rest of the empty block white or
gray (preffered solution)
B) Having the color gray or white...
