View 2 Repliesi frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?
View 2 RepliesIf I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.
View 1 RepliesI am using Visual Basic .Net 2005 professional.From what I understand, I should be disposing of any object that is an unmanaged resource. I understand the best way to tell if a resource is unmanaged is if it has a Dispose method. ie: If I type a dot after my object, intellisense shows .Dispose() as one of the options. If it does, it's an unmanaged resource. Is that correct? In that case, pretty much every control is an unmanaged resource: buttons, forms, panels, etc.In the application I am working on I use an MDIparent container form, which contains MDI children forms, which themselves contain Panels, Menus, Groupboxes, etc, which in turn contain Buttons, Textboxes, Labels, Dropdowns, etc.Do I have to dispose of each button, textbox, label and dropdown within a panel before disposing of the panel?
Do I have to dispose of each panel, menu, and groupbox before disposing of the MDI child form?.Or can I just call the Dispose() method of the MDIchild form and the GarbageCollector will take care of all the controls and resources within the form?Watching the "mem usage" in Windows Task Manager seems to be an unreliable way to detect if I have a memory leak. The numbers just keep climbing and falling (mostly climbing) erratically and without any activity performed on the application. Is there some (relatively) easy way to detect leaks?

I created a custom control that uses a PictureBox and made that PictureBox movable.
I create the control during runtime and the code works just fine. I can move the picturebox, except it can only move within the bounds of the control, which is the same size as the picturebox.
I have a panel that has a label and a picturebox inside of it and I handle the pictureboxes event like so:

What does this error mean? I havent modified anything in the designer code, but its giving me an error?

adding the properties of a control to its parent? Without having to rewrite all the properties... For example, if I have an user control with a button inside, and I want to have the "text align" property of the button, in the list of properties of the usercontrol. If not, is there a way of making the child control of an usercontrol editable?

View 1 RepliesI'm creating an app for school to mark targets that we shoot in shooting competitions. Now I have created a dll in C# to do the marking bit and it works.Now the problem I am facing is that my app gets a image from the scanner (A4 size @ 600 dpi) and putting it in a picture box.There will always be 20 targets to be marked per image( However I want this to be able to vary to provide flexibility) My dll accepts a image that contains a single target so I need 20 individual images of targets.Create Drag able Rectangles in the picture box and crop the images from there . There are 2 ways of accomplishing this.
#1 Create a Control and set it's parent to the picturebox. (This should provide a location relative to the picturebox Right ?)
#2 Use only GDI (eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeew)
so my choice would be to create a control except I have never created any control from scratch and I have no idea how to do the visual drawing part of a control.
I've made a ContextMenuStrip to use in my program to change the image in a picture box. However, it's used with multiple picture boxes which each need to have their own changed. What I want to do is make my command change only that picture box leaving the others as they were before. An example, if this were a plausible code.
Private Sub TestToolStripMenuItem_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TestToolStripMenuItem.Click
Self(aka the control that currently has the menu open).Image = My.Resources.Picture
End Sub
I'm creating a user control that contain ToolStrip and some ToolStripButton, and i named it as 'myToolbar'.

I created a custom control (inherited from a panel). Then I created some other custom control (textboxes)
I add the panel control to the form, then I add some custom textboxes inside the panel.
Now, if I remove the panel, the custom textboxes don't move. I think, because the custom panel control isn't the parent control of the custom textboxes.
How can I modify my custom textbox class, if I add the textbox to a form, to a panel, to a container, it should have that container as parent.
I have a .aspx page that loads three separate .ascx controls to represent adding, editing and listing objects. It currently simply swaps out visibility and enables/disables the controls to switch between pages.However, when listing objects (in a gridview), we offer the basic "Edit" button beside each one. Clicking on this will, obviously, load up the edit control for that user. This functionality exists inside of the control, rather than the parent page. Is it possible to modify attributes for the parent based on events occurring in a child control? (For example, change the visibility and enable/disable the other children controls)
