I'm doing a complete rebuild from the ground up - which allows me to address issues that have arisen over the life of my vb6 application and I'm also learning .net as I work. My primary concern though, is that on one of my forms I display all the information about a customer (Name, Address, Notes, Phone Number, Assigned Salesman, etc.) in VB6, I put all the textboxes in a frame and disabled the frame so they boxes looked "normal", meaning there were still white with black text.

I need to create a solution in which I populate some rows with data from a database.In those rows I put usernames and total values (total resulted from products selled in one month by every user)The idea is that I need to make somehow that when I click on one user (event CellContentClick on DGV) to expand the user in the way that I can see all products selled by that user in the selected month.I readed on the internet that I have to use datagridview inside the datagridview.I was thinking maybe I can have some expandable rows inside the datagridview (like in Excel) and when I click on + sign to expand the rows and to populate with selled products.

I have a routine which allows me to expand the size of my DataGridView within a TableLayoutPanel. Effectively it repositions the DGV to the first row and first column of the TableLayoutPanel that it is in using the SetRow and SetColumn methods of the TableLAyoutPanel. Then it sets the column and row span by passing the row and column count properties of the TableLayoutPanel to the SetColumnSpan and SetRowSpan methods. It work fine. There are two buttons on the form, One expands the DGV the other returns it to its original state.
My question is, how would I set this up if I wanted to do this for all the controls in this TableLayoutPanel and/or every control on every other TableLAyoutPanel on my form. I am assuming I have to use a class as I would have to create an abundance of public variables to pass the row/colum and row/column span starting positions to.[code]....
In many apps I have needed to disable the maximize and resize features of the main window because the textboxes and buttons stay exactly the same without realigning or resizing automatically. How can I change it so that buttons maintain their proportions and that textboxes will stretch when the window is resized?
View 3 RepliesActually, I'm not looking for the way to expand its width.I have a combobox with a given width.It may occur that one row of the data is partially hidden. I'd like to show the whole line by using tooltip or right-click context menu.What do you think? What's the best approach for this scenario? Anyway, I can't find how to 'catch' the row that I'm currently holding on or passing over by mouse.
View 6 RepliesI have a combo box on a form that is set to certain width. The data the combo varies and can be quite large. Is there a way that the combo box could be expanded to fit the widest data/text when the Combo is selected?It would be quite neat if it pop out of the form when selected! I guess I could create this effect by creating another form that opens when when that object is selected.

I am trying to make a form expand from one size to another using a slider animation.
The problem is when I run it the form resizes but without the animation. I'm not sure how to use the animation when resizing the form. It works if the form is a set size and then I run the animation.
The form is borderless and starts out with a width of 11 and I want the final width to be 285.
The resize and animation are triggered by clicking on the form.
Here is the code.

Me.Width = mintformmaxwidth
