I have a gridview and I need to know the number of rows in it. I find
the Page_load and the Gridview_Load events are too early to find out
the number of rows. I can use the Gridview_databo und event to check
for the number of rows. But the problem is that the user can update a
field on my form, which reduces the number of rows in the gridview,
because the gridview SELECT statement no longer finds the records when
their flag has been set to False.
For instance, if my gridview shows all people who were enrolled in a
college, and the user sets a flag that on the form that means one of
the people in the gridview is no longer enrolled, the gridview should
shrink by one row. I need to know when the gridview shrinks to zero
rows, and I don't know what gridview event I can use to tell me that.
Thanks,

Interrogating the GridView control to discover the number of people
enrolled at any instant is not the best way. Use a database query so
you get the real up-to-date picture independently of the state of the
GridView. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hi all, I've got a really annoying problem that I need to fix sharpish.
I've got a GridView derived control which has a templated header and
footer. It works wonderfully on the first render but then the
header/footer vanish into thin air. If I add the header/footer
onDataBound then they disappear when I do a postback with no
databinding. If I add them during PreRender, then they persist, but one
of my data rows is emptied for each time I...

I have a gridview on my form which I have populated using a

records from the gridview, without affecting the source of the data.
I'm a bit confused about how to go about removing the rows - all the
google searches I have done so far seem to assume that the grid view
is bound and the programmer wants to delete the data from the original
source. Is there any easy way to...

I have a gridview that has a blank row with 2 input fields: file to upload, and a description of the file. They click Add and a new row is added, Remove and the row is removed.
The problem is:
When a new row is added, I loop through the existing gridview rows, store the data in a dataset, and rebind. In debug mode, I see the values I entered but when I rebind, it's not displayed in the gridview.

For tables with large number of rows, it is difficult to access the rows
with high page number due to high volume of data. Currently the user is
required to click the "..." link many times to get to each successive table.
Instead of only display few page index, is it possible to make GridView
display all page index?
Thanks

Hi I have a gridview with one of the columns as a template column with a

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
