C# :: Call Function From UserControl On ASPX From UserControl On MasterPage?
Jan 31, 2011
I have MainLayout.master that has UC_Menu.ascx on it. I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:
IsLocked (a boolean indicating if the following two properties are "Locked") IsLockedID (if IsLocked=True then IsLockedID is an integer) IsLockedName (if IsLocked=True then IsLockedName is a string)
I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName" Dim MyControlType = "TextBox" Dim MyStringValue as String
I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?
Code in UserControl:
Public Property DBItems() As List(Of String) Get Return DBItems
I have a tabcontrol that creates tab pages from a "User Control" I created (a separate form in vb.net) using this code: (MainTab is the separate user control I created which has text boxes etc in it)
Dim tmpTab As New MainTab myTabControl.TabPages.Add() Dim tmpTabCount As Integer = myTabControl.TabPages.Count myTabControl.TabPages.Item(tmpTabCount - 1).Controls.Add(tmpTab) myTabControl.TabPages.Item(tmpTabCount - 1).Text = "Untitled"
I'm using the devexpress xtratab control so the code might look a bit different than the default vb.net tab control.
Now in my MainTab user control file file, I can't for the life of me figure out how to call a control in the form1 where the xtra tab control is placed on. "Me.Parent.Dispose" works for closing the tab when executed via the MainTab control, but that's as far as I can get for communicating with the parent from.
I'm not sure if I have to reference something in the MainTab user control or what in order to communicate with any objects on the default form1.
I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.
I need to get a value from an API I made with ASHX and normally it is called from javascript but I need to call it right in ASP.NET I figured this shouldn't be a problem but I'm not sure the syntax.
i have the following function in default.aspx i have webusercontrol which have 10 checkboxes and 1 button i want when i click on button1 of user control then it can access the function of default.aspx page ...if i dragged the usercontrol to default.aspx
I am trying to convert a DLL function call which has the Callback function routine called within the DLL function call.The DLL function call signature is like this:
I have created a usercontrol named note. in the note usercontrol in contains 6 labels. now i want to access the usercontrol at runtime. it means that, when the right button is press, the note usercontrol is appear, when it pressed again it appear again beside the previous usercontrol. how can i access it like when user is click at one of the labels, that labels backcolor change to other color. it is means that a label that has been clicked is the selected label. and we can change the properties of that selected label.
I got a user control that has a few links, one of them is "add article". It's placed on top of the article and bottom of it. When the user clicks on it, the text changes to 'article added'.
But the text only gets changed for one of the links which has been clicked on. How can I make it so that both text changes no matter which one gets clicked?
I am trying to develop a control that'll allow the developer to populate a collection through markup (e.g. Properties decorated with the attribute PersistenceMode(PersistenceMode.InnerProperty). I have an example from Brian Chavez that more or less does what I want but I want to have the control inherit from UserControl and not Control.Here is the code I have in vb.net:
AggregateFeeds.ascx.vb Imports Microsoft.VisualBasic <ParseChildren(True)> <PersistChildren(False)> Public Class AggregateFeeds
[Code]...
As it is now when I try to compile I get a compiler error that simply says object instance not set to an instance of an object on the line above. If I take it out, the page loads just fine and the Settings object reflects the values in the markup. Why am I having trouble getting the collection to populate correctly?
I created Custom Paging User Control for a GridView. The Custom Control I am using at the top of GridView and Bottom of GridView. If I am clicking Next on top of Grid View, it is not effecting in the bottom.
I created a UserControl in a ClassLibrary project and then built it to generate the .dll file. I then want to create a new project and i added this .dll as a reference to my new project. but how do I add the UserControl in the class to my Toolbox? I'm using Visual Basic 2005 Express Edition.
I am running through an issue for which I am unable to find a solution.My goal is to:1- compile a x64 .NET library (vb) which has a simple User Control 2- Use this dll in a .NET WinForm application targeted to x64 CPU ONLY.
I have been able to do the first step, but now I am unable to add the library into the VisualStudio Toolbox. With our previous x86 version we had just to right click to VS toolbox, click on "Choose items...", then brows to the needed x86 assembly. If we do the same selecting a x64 lib (of course I am running vs on a 64 bit OS), we get the following message "[DLL PATH] is not a Microsoft .NET module."
I've created a usercontrol in VB that handles paging more efficiently than the DataPager (at least for very large datasets). I'd like to use it in a C# project, but I've been having trouble getting it to work.I've tried simply adding PagingControl.ascx to the C# project, but when I do that the markup and VB code behind don't seem to see each other. --Is this a namespace issue?I've tried adding the PagingControl.ascx to its own VB project, then adding that project to the C# project's solution, as well as a reference. --That almost works. I can register the PagingControl usercontrol in the markup. I can access the usercontrol's properties in the code behind, but any property that involves the UI of the usercontrol fails.
Its seems as if the usercontrol's form hasn't had a chance to load by the time the C# page's Page_Load event handler fires. --Maybe this is an "order of operations" problem? At what point in the C# page's lifetime should a usercontrol's form be loaded?
Have actually managed to create a UserControl complete with buttons, windows media player ... Right-Clicking in the toolbox I browsed to the dll and that brought the control into the toolbox successfully as VideoSourceControl.I can drag/drop this control onto the form and it is fine, buttons etc looking good. Now I want to create it programmatically - I actually want to refer to an array of them.On the form load I have
Public mySources() as SourceVideoControl and I get an error saying that 'SourceVideoControl is not defined'The dll that I loaded was called VideoMixerControl.dll?
how to use a ToolTip on a UserControl? I have a UserControl with some TextBoxes on it & I am adding the UC to a panel on my form at runtime. Now I want to set the ToolTip text for one of the TextBoxes, but I can't figure out how to do that. I have added a ToolTip component to my UserControl at design time.
I made a User control.I add two Panel in this Usercontrol. But i want one of panel keep control like container when i add my usercontrol in the from.but when i add user cousercontrol does not contrin any controlntrol in the from but my . how can i user usercontrol like container
I believe I am on the right path but didnt get it to fire. userControl1 contains a lstBox, it has MouseDoubleClick event doing something inside the userControl. But I want to add something to that event from the form containing the userControl1. So when I mouseDoubleClick the lstBox inside UserControl1 I want to fire the code in my form eventHandler and in the control eventHandler? RaiseEvent?
Public Class myForm 'CodeBehind of form containing userControl1 Private Sub UserControl1_MouseDoubleClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs ) Handeles UserControl1.MouseDoubleClick ds1.clear() [Code] .....
I have a usercontrol I created. I added a panel and a vertical scrollbar to the right of it. I'd like to be able to scroll it with the mousewheel. The problem is there doesn't seem to be any events that fire on mousewheel. If I take the panel off then the usercontrol has focus and it will fire on mousewheel in the form. But with the panel on it doesn't seem to fire the mousewheel event of the panel, or the usercontrol within the control or even on the form. The best solution would be to have an event fire in the usercontrol but I'd even accept an event on the form and feed it back into the usercontrol.
