Forms :: Dynamic Controls Disposal - Only 50% Of Controls Removed?
Sep 17, 2010I have a query about dynamically added controls to a form. I have a series of buttons which are created and added at run time. I have a two drop down lists and two buttons which are created at design time. Button 1 creates a series of buttons called "Test 1.x" based upon the selection of the two drop down lists. This works fine and am happy with the logic.However.... Button two should remove all the dynamically created buttons from the form.This does not happen. What does happen is that 50% of the buttons are removed starting with the first one. WHen checking the loop it only enters the loop half the amount of times that there are buttons. Very strange. When the loop is run repeatability it will remove all controls. Why will my logic not remove all the dynamically created controls at once? What is wrong with my logic?
I attach two code snippets and the .net file for your consideration.Button method which creates the dynamically created buttons from the two drop down lists and adds to form

Manage Controls If There Are Many Many Controls Placed On The Forms?
Dec 10, 2006I would like to know how do .net developers manage a large window application with a large number of controls, such as textbox , button, groupbox? I have seen a number of people do it this way : declare the controls as an array and initialize them one by one at run time . In this way it is easy to manage those controls because they can be accessed by array index; but this solution seems to require very good understanding of control's attribute such as its location, font etc. This could be a difficult task if the project is passed on to a less experienced developer and add changes to it.How do you deal with it?

Changing A Specific Property For Several Controls At Once?
Apr 24, 2012Let's say I've got a TableLayoutPanel with 50 cells in it. Inside each cell is a separate text label. If I want to change the color of each of those 50 labels at run-time to the same color, is there an efficient way to do it? (so that I don't have to write 50 lines of LabelX.ForeColor = X, etc).
Not that I would mind writing 50 lines of code for this, but I would like to figure out the most efficient way to do this sort of thing, for future reference.
Property Editor For Array Of Controls
May 21, 2012If you have a Component (or Control) with a public property of type Control, then in the Properties Window you automatically get a drop down of all the controls on the same form as the component, which is very handy. If you want to do the same thing but with an array of controls then the Properties Window shows the ellipsis and you get the Collection Editor with the Add / Remove buttons creating and deleting an instance of Control (i.e. the base class used for deriving all the others) - not quite so handy.
How do I get a list of the controls on a form and be able to select more than one? I think I need to create a custom UITypeEditor? Assuming that's right then I think I need a dialog box (like the Font dialog) with Available and Selected ListBoxes with Add / Remove buttons and appropriate code to link the control array in the component to changes in the Selected list box? Along with an appropriate UITypeEditor derived class.
Assuming that's correct, how do you get a list of the controls on a form at design time? Can I do that form design as a Windows Form, just as normal, or is it all done by hand? I've seen some code that does it with a UserControl rather than a Form, presumably that's for when you want a 'pop-up' control (like the one for Color selection)?

View 8 RepliesSql - Equivalent For Value-property For Controls In Winforms?
May 3, 2012I'm used to webdeveloping, and when I work with databases, I usually use some text for the Text-property of a radio button, and the row's ID as Value-property. This makes it very easy to save to databases.
Is the an equivalent in winforms for the Value-property, or will I have to identify rows based on the text in the control?

Preventing Controls Enable Property From Changing?
Mar 9, 2010I m implementing control based security in my application. where i m saving controlname (per form) in database, which are to be restricted. So far I have implemented the security and restricted control get disabled.
Now what i want to do is that i have to prevent that for those controls the "control.Enable" property should not change. how can i restrict that.
I have achieved the functionality by canceling enable=true property in "Invalidated" event of the control. but this is not some generic way. I have to map this event for all controls in all forms :(.
What i really want is that as all my froms are derived from same parent which implements the security. so the parent should some how restrict enable property from changing.
So,HOW CAN I PREVENT CONTROL enable property from changing in their parent class?

Forms :: TreeNode Value Property Missing
Mar 9, 2009It seems that Visual Studio is using a older verion of the System.Windows.Forms DLL.
When I instantiate a instance of the TreeNode object it doesn't have the "value" property. Right now my version of Sytem.Windows.Forms is listed as 2.0.0.0 and it's being pulled from the Microsoft.NETFrameworkv2.0.50727 folder.
I've installed all of the current .NET framework service packs....
Is there something else that I need to do so that the I load the most current version of this object?
8 Bit GIF - Transparency / Forms And Controls
Apr 3, 2012I have a 8 bit Gif, that is transparent, with controls sitting on top of it, all in a custom control. This part works fine. However, This control is a menu ring (appears around another control with a few options). The transparent part is over a Picbox, that is in a panel. The transparent part of the image seems to skip the picbox and go right through to the panel. I set the panel to a back color of RED. The custom control when its placed instead of showing the image in the pic box that it is on top of, it shows the RED panel I have made sure all my Z orders are right.

Forms - Resizing Controls Accordingly
Feb 12, 2011we all know how to dock or anchor controls so that they resize themselves accordingly when a form is resized. It works fine till we have rows of controls on left and right size of the form. But what if have three columns (Columns as in visual sense. I'm not talking about any column control containing other controls) of controls? For example a form having a bunch of controls in the left side, a bunch in the middle and a bunch in the right. There may be a few more bunches in the middle. Now while resizing the form, I want the controls to resize accordingly as well as change their positions to make space for the previous bunch of controls that are resizing.
I mean, while the user increases the form size horizontally, the controls of the second bunch should resize and at the same time they should move right because the controls of the first bunch are increasing horizontally too. When the user decreases the form size horizontally the same thing should occur in the reverse order. I can manage it somehow using nested split-containers but that's too cumbersome. I would like to know if there's some better way to achieve it, like setting some property etc.?
