19 New Member
I have a unbound datadridview named dgv_add, which contains columns of type datagridviewcol umn types and the another column of type datagridviewcom bobox type. I want to add specific items from a database depending upon the inputted text in the column of 1st type. I mean I want to retrieve specific column from a database and add the available items to the combobox after inputting text in the column of 1st type.
eg:
DGV_Add-> datagridview
Mdcn_Name->datagridviewco lumn
Mdcn_Pack->datagridviewco mbobox

PLZ HELP.
Thanks In advance.

I have a combo box with a NotInList event on it that allows me to add a value through another form. When I return to the form that contains the combo box the value I added is at the bottom. How can I get the combo box to sort the values alphabetically so that the value is where it should be for the next record? The control source is just a field, not a query, so there is no "sort by" option that I can find in the Properties. thanks for any...

My client passes an EventShim with a callback to the server. When...

Overview: 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,...
