I want to have a DataGridViewColumn, only have it use the ComboBox, then
when they drop down the combobox, open up another datagridview instead
of the combobox dropdownlist. The reason I want to do this, is so I can
show more than one column at a time in the drop down list. Instead of
trying to make a multi-column combo, I thought it would be much...

1- Inability to easily reset datagridview combobox selection to null
Solution - add a contextmenustrip to the column in which you have the
combobox on the datagridview. show to user, something like Remove selection.
In the onclick event
Me.Datagridview1.CurrentRow.Cells.Item("YourColumnName").Value =
System.DBNull.Value
2- You can use same technique for ordinary comboxes, instead of row in
datagridview set value of the combobox bound...

I have a DataTable that I want to fill using a DataGridView. I've set the
DataSource of the DataGridView to my DataTable. My problem is that I want
some of the columns to be drop downs. For example, the user will need to

I am having a problem with my datagridview. I have a small table that
has two columns. The first column is bound to my dataset. The second
column is a combobox. I add items to the combobox based on the
information that I get from a text file. I then try to set the value of
the combobox to a specific value based on the first column.
The code is working to set the value, but it will not refresh and
display the selected value on the screen...

Hello All
In my windows application I am using DataGridView as my grid control. I
populated let's say 10 rows of data and modified 3 random rows. I need to
put some sort of Edit Marker in the row header. This can be an image. Please
any one share a code for this implementation.
If i were to save this records, how can I trap those 3 modified rows without
going throgh the whole row set?

My DataGridView has two columns. Combobox Column 2 displays list based on Combobox Column 1 selected value. The code below works fine when I select a value on Column 1, and select a value on Column 2. But on the next row, when I leave Column 1 blank and click on Column 2, it generates error DataGridViewComboBoxCell value is invalid. And the code below works fine the first time I click Column 2, leaving Column 1 blank.

I have an unbound datagridview with three comboboxes (e.g. A, B, C) All three comboboxes share the same datasource and use the same valuemember. If I change the value of say combobox A, then B and C change also.
My problem is that B and C do not show the update until after I click off of combobox A. I want B and C to update as soon as I make the selection on A. How do I do this?
Thanks,

I'm having a really strange issue with the DataGridView control in a VS2008 / .NET 3.5 winforms project. I have a simple form with a grid. In the form constructor I call a function to bind the grind to a DataTable, and then loop through the rows setting the background colour of the last cell to LightGrey and the cell itself to read-only if the column value is true. After the form finishes loading the code didn't work i.e. the cells are not set...

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...

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,...
