User Conrol Mouse Events From Controls Added To The Usercontrol?
Dec 7, 2009I am trying to make a small control that has a picturebox and a few labels that can be dragged on the form it is placed on. The control was easy, and I can drag it fine when the mouse is down on the control, where there are no other controls, like not over the picturebox or labels.
When i try to click and drag the user-control and the mouse is on the picture box or labels of the control the mouse down event is not detected. I am hoping someone can tell me how to pass the mouse-down event from the controls on the user-control so the form I place it on detects the mouse down even no matter where on the control i click.

Controls On Inherited Usercontrol Are Invisible?
Jun 26, 2010am trying to make use of inheritance to keep consistency in my user control appearance. I created a usercontrol to use as my base design, as a platform to link to a tab as acontainer. To this I added a few framing visual items like a header panel andsome labels.I then created another usercontrol that inherits from my base control, with the intention of adding the necessary items to this derived control to build it into a complete functional usercontrol that I can associate with a tab on my main form. I want to keep the visual appearance consistent across all similar derived controls. Then later if I change the design of the base form, this flows through to the derived controls.

Creating A Container Control Out Of A UserControl Can't Access Controls At Runtime?
Oct 16, 2009I have created a usercontrol that contains two rectangle shapes to create a unique button effect and a rounded-corner rectangle shape serving as a border to provide a look similar to a group box. It also contains two labels, one for use with a Text property of the control and the other to indicate the status of expansion of the control. The control is designed to collapse itself when the "button" is clicked leaving only the "button" visible. Clicking it again toggles this affect. I've dubbed it an ExpansionBar. It is also designed to be a container control so that I can add controls to it and allow these to disappear when the bottom portion collapses. The problem is that the controls contained in this usercontrol cannot be accessed during runtime. In other words, I can add a checkbox to it and it will disappear correctly when the control collapses, but I can't select the checkbox to check it... same thing with any other controls, you can see, but can't touch. I'm a novice developer, so I'm sure I'm missing something obvious.
View 12 RepliesManage A Large Number Of Similar Controls In A User Interface (such As Button Or TextBox Controls)
Aug 23, 2011There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

Custom User Controls - Correct Size With User Choice
Sep 27, 2011I have some custom user controls in my .net winforms program that do not display correctly when the user has selected larger text size. This setting:
My controls look like this:
Instead of like this:
The bill to area and ship to area are both custom controls. I don't know if this is contributing to the problem but I do have code in each to scale the phone/fax areas to stretch nicely, like this code from the bill to control,
Private Sub panFaxPhone_Resize(sender As Object, e As System.EventArgs) Handles panFaxPhone.Resize
panFax.Width = (panFaxPhone.Width / 2) - 1
panPhone.Width = (panFaxPhone.Width / 2) - 1
panFax.Left = panFaxPhone.Width - panFax.Width
End Sub
How can I get my controls to size correctly while still respecting the users choice for larger text (I don't want to just set the AutoScaleMode to None)? After playing with this for a long time it seems to be a problem with anchors in the child controls. See this below image, the inner black box is the control with its border turned on, the text boxes (like name) are anchored left and right and should stretch to fill the control, but don't.

View 1 RepliesAsp.net - Getting Information (on Click) That Was Used To Programmatically Generate Asp Controls?
Jul 15, 2009How may one get information that was used to programatically generate asp controls?For example, I pulled a DataTable of user objects from the database and have organized them on a page, listing groupings such as a list of employees directly under the employer for each employer. On the page, I list each user's Username as a LinkButton. When I click one of these employees, I want to redirect the page (which is easy) and set a session variable to the selected user's UserId (which seems not so easy). How can I pull this UserId value back? These elements are not hard-coded with nice names (as they are generated in a for each loop).
Code from comment below:
Dim lnkbtnPm As New LinkButton ' is my link button. '
lnkbtnPm.Text = pmDr.Item("Username") ' where pmDr is my datarow. '
lnkbtnPm.CommandArgument = pmDr.Item("UserId")

VS 2005 Getting Information From DataSet To Populate Defaults In Controls?
Jan 27, 2011I have a form that has many controls. My next task is to populate the phone number (MaskedTextBox) and phone number type (ComboBox) when the cursor has lost focus from a ComboBox that has auto complete functionality. I have tried to do it and when the cursor leaves focus, the other controls are not populated. Nothing happens. I do not get any errors either. Screen shot attached for the form and I am also using a stored procedure to do this. There are two tables in question here. A client table that the name and phone number and then the second table that has the phone number type (cell, work, home, etc).There is an FK relationship between the two.
This is my stored procedure. It is called sp_GetClientInfoByName.

Logged In User Information?
Jul 20, 2009I'm writing software in VB .NET (2005) which uses the Windows user information as login credentials - just the username. I've found Environment.UserName which works for the username (as you would expect).However, I need more information - I need the full name of the user (as shown on the Start Menu). It seems this information is stored... somewhere, as Windows is able to use it for things like permissions on file shares.
