I don't think that it is possible to add a combobox to a single cell - you can have a comboBox column on the DGV. If you want it on a single cell then you are going to have to write a usercontrol

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Perhaps if you explain in more detail, and maybe give us an example?

No, don't send a picture: describe it!
You can't post pictures in questions, and very few people here will follow "random" links!

How do you get the data into the DGV?

Member 12439771 4-May-16 12:11pm

by this code :
dataconnection()
Dim da As New OleDb.OleDbDataAdapter("SELECT * From visits", cnn)
Dim dt As New DataTable
da.Fill(dt)
Me.DataGridView1.DataSource = dt

I have no idea if this will work in your system, but...

C#

DataGridViewComboBoxCell myCell = new DataGridViewComboBoxCell();
myCell.Items.AddRange("Hello", "there", "world");
myDataGridView.Rows[2].Cells[3] = myCell;

Will do it.
However, depending on the source for your existing data, you may get DataError exceptions.
