refresh datagridview automatically

17 New Member
Hi,

I have a Window Form to which i added a datagridview. The binding source is working well, but does not update if the database is modified outside the application (i mean not showing the modification made to the database).

Trying to solve my problem, i added a timer to the form that Fill the datagridview every xx milliseconds (basically a timer that calls the Form_Load method). The timer is working nicely, but because it always refresh the grid i can not "work" with the grid, can not add or delete any row because the refresh is too fast. If i change the timer delay for longer delay, i do not see the "real time" changes made outside the program.

What i would like to do is Fill (or anything else) the datagridview only when the data in the database is changed, so i could work in the datagridview of my form and also refresh it when changes have been made from outside the program.

I'm using VS 2005 Framework 2.0 and my program is C#.

Thanks in advance for your help

Maybe have your timer check for changes first and then if there are changes refresh. Alternately stop the timer while in edit mode and then start again after editing. HTH.

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: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

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,...
