Combox that contains letters textboxs stop working

Question

I'm working with Form 1 I have 15 textboxes and 2 combo boxes. You can select from the combo box exp: 123, 456 B789. Program works well as long as I dont select B789 has a letter in it. I can change it to 123 or 456 and i can add to any textbox. The Letter has stumped me.

 

In the beginning my dbo.Table was set to Numric for the combobox I have changed it to Varchar but it still dont work.

 

If I try to add to any other textbox with a letter in the combobox  it stops.

 

what else should I be looking at?

 

Answer 1

There's a couple of ways you can do it. You can create a panel containing all the controls you want for the advanced mode, and set it to be not visible by default. Now the button you press can alter the visibility of that panel. If you place all of the controls in a Panel called panel1, add this line to your button click event: this.panel1.Visible = !this.panel1.Visible; Add anything else to modify the text of the button if you wish. Another way to do it might be to create two different forms, but have one be the advanced, and the other the basic. There might be a good way to do that using inheritance, but having never done that myself, I can't give you too much input on it.
