I have a couple user controls that are loaded by a Select Case statement. However, in the behind code file for the main page that loads these controls, none of the asp controls show up in intellisense. I had a feeling it's because the controls are loaded conditionally. My question is what is the best way to solve this?
1) Load the controls and do a Select Case in the behind code to make them hidden or not.
2) Is there a way to say (psuedocode): LoadUserControl("UserControl1").Controls("tbTest").Text = ""
3) How can I pass a dataset to the User Control file?
After taking a few years off from programming, I decided to start learning vb.net. I have created a user control that contains a picture box. I added some custom properties to the picture box that will hold general string data from a database.
My problem is that the user control is programatically created during run time, and during this time a DoubleClick event handler is added for the picture box that is within the user control.
I need to be able to set the custom properties for the picture box during the creation of the user control, so that when the control (picture box) is double clicked I can read these values but am unsure on how to access them.
The picture box is the entire size of the user control, or I would just add the custom properties right to the user control and add the DoubleClick event handler to that. However, double clicking needs to be done on the picture box since it takes up the entire user control, unless anyone has an idea to trigger the DoubleClick event of the user control when the picture box is double clicked.
i have a windows from project and in that project i created a user control lets call itcustombutton1 now i can use that control quite easily either at design time or runtime by creating a new instance of it like
I have a user control in which there are some controls. Now when I bind the usercontrol to db and show it in a panel (dock fill) it shows some odd behaviour like contols are painting one by one and this is looking odd.Can anyone please tell me how to fix these type of issues.
In my asp.net 4.0 application I have a standard set of tabs controls across the application that has one tab for Search, one for View and one for Reporting.I am in the process of updating those tabs and I was hoping to be able to wrap their functionality up into a single user control since they all function in pretty much similar ways. The issue I am having is how to create a property called SeacrhTab/ViewTab/ReportTab that allows me to assign a different user control to it depending on the area of the application (e.g. CompanySearchControl, ContactSearchControl, etc.) Anyone ever tried to accomplish something similar?
I am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.
I have created a website that works perfect on my machine but when I posted to the server every thing works but the create user and Login. I know when you run it on your machine it saves users at the Web Site Administration Tool. What do I need to do to make it work on the server.
I've created a user control that is basically a Panel that contains 1 label,3 TextBoxes and a few properties that set/get some short integer values.During a form load event I display a number of these Panels.I then access the Panels name (and other panel properties) via a user-created handler for the panel's click eventHowever I would really like to access the values from the user-control's properties.
Public Sub load_Panels() Dim pnlName As String Dim x As Short = 69
I have a form named VBProject It has two TextBoxes and one custom control named MyControl which is created in another project.MyControl's project has a form inside, named Form3. When My control is loaded it needs to find all controls in my VBProject and add them into a listbox which is in Form3. Then Show the Form3. In the end ListView need to shows name and text of textboxes but it shows nothing. Here are my codes:
MyControl's Load_Event:
Dim i As Integer = 0 MessageBox.Show("Control Count:" + Me.Controls.Count.ToString) For Each MyObject In Me.Controls If TypeOf MyObject Is TextBox Then
I am trying to delete a customer record. In the page I have an usercontrol for address and it has some validation. I cannot delete the record since it fires the validation controls.
I want a list of all controlls in my project, not only on open forms. The reason is that i want to make an access control, and the admin will set which buttons each users can use.
What ive got so far is:
HTML
Public Sub getallforms(ByVal sender As Object) Dim Forms As New List(Of Form)() Dim formType As Type = Type.GetType("System.Windows.Forms.Form")
[CODE]...
This shows me all forms in project. But i cant access their controls.
I 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.
I have a windows application with a main form, on which a user control is added dynamically when a device connects trough USB.
On a user control, there is a thread wich is getting data from the device trough USB and when it is finished, I want to change a progressbar that is located on the main windows form where user control reside.
This is the code that is I call on the user control thread to change the progress bar value:
Frm_Main.UpdateProgressBar(CInt((AllBytesReceived / MaxBytesInFlash) * 100)) and this is a code that is called on the main form: Private Delegate Sub UpdateProgressBarDelegate(ByVal value As Integer)
I created a User Control and I used a button to "call" this control. However, when it shows up, it's being covered by other controls. How I can make sure this control on the top?
There 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.

I have an application going here Form1 has a panel on it named TargetPnl. I need my TargetPnl to display my user control named Vviewer when I click my SearchBtn and also need it to disappear when I click another button.
how can i call a VB function - deleteevent() in usercontrol.ascx.vb from a javascript function in clickhandler(e) in usercontrol.ascx. The call should cause a postback because I need the usercontrol to display the changes.I am currently trying to do it by using a linkbutton with style display:none, and calling its click event from the javascript function. But i dunno how to call the click event.
I've been building controls for many years professionally and personally, but even back in VB6 days I just could not work this out. After all this time I remembered about it again.If I create a usercontrol/containercontrol and add one or more controls to the controls surface, I just cannot figure out how to access the controls at design time.
I have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.
I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?
I have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.
I 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.
I now realize that it is incorrect because the container's InitializeComponent property initializations have not run yet and they must be run prior to Refresh being called.
How (where) can I run Refreash after the container has initialized this user control.[cod]e...
