| A real Windows Forms question for the list (9 replies) |
| ASPFriends.com 'winforms-cs' list |
| Moved from [winforms community] to [winforms cs] by Charles D. Carroll darthcarroll@asplists.com So, being that people aren't actually talking about Windows Forms on this list, I thought I'd throw one out to the crowd. I have a combo box on a form with data that is filled by a DataSet. I also have a function defined for SelectedIndexChanged. The problem is that this function fires when the data is... |

| MDI applications (2 replies) |
| ASPFriends.com 'winforms-cs' list |
| I have ploughed through a book on C# and also some documentation on the web. Is there any way for an MDI parent to tell which child should become active? I would like to program a TabControl to control childs similar to what's done in CuteHTML (www.cutehtml.com). Is this possible at all? Yours sincerely, Thomas Breivik |

| Calling a method in Form1 from Form2 (4 replies) |
| ASPFriends.com 'winforms-cs' list |
| As I've stated in another entry of mine, I get a object reference error when I try to do this. I have two forms who share the same namespace. When I try to call a method in one Form from the other Form, I get the error. I do a simple NameSpace.Form#.MethodName(); call, yet no go. It is somewhat important for me to find out if this is possible or not, or if I'm doing something terribly wrong. With ... |

I'm trying to send a method call to the MdiParent from the MdiChild, but no luck. In MdiChild, I have a simple PPM.Form1.blahDiDa(); method call. blahDiDa() only has one statement, a simple statusBar1.Text "Blah!" call. Yet it doesn't work! If I put the blahDiDa method a... |

Is this possible at all? If not, is there a way of determining displayed childs and then set one of them to be visible?

| DataGrid - Why? (4 replies) |
| ASPFriends.com 'winforms-cs' list |
| Hi group, I really dislike the design of the DataGrid. If you want to display an Image, ComboBox or any other control in a DataGrid, you need to first code an object that inherits from DataGridColumnStyle (i.e. DataGridImageColumnStyle for images). This is unessecary, since all Controls inherit from System.Windows.Forms.Control anyways. Wouldn't it make sense to have a generic ColumnStyle that cou... |
