I'm having an issue with my tabpages. I have a particular Windows form that contains a TabControl with two TabPages. The first TabPage contains a DataGridView (DGV). When a User double-clicks on a row in the DGV, the data is loaded into various controls and variables and then the second TabPage is selected.
Now, on the second TabPage, I have several ComboBox (CB) controls. The way my logic is set up is that when the User selects a row from the first TabPage, certain values are are assigned to the "SelectedValue" of some CB's. When that happens, the SelectedIndex Event of the CB's fires and processes data accordingly. This works fine except for the very first time a row is selected from TabPage 1. The CB's SelectedIndex Event fires but the different controls don't get populated correctly. Once the second TabPage is shown, then this whole process works as it should. It's just on the initial row selection from the first TabPage.
Does anyone know why this happens? I hope I've explained this issue correctly.
