VS 2008 Move A Control From E.g. The Main Form To A Tab Page
Oct 21, 2010What I'd like to do is in my application move a control like a groupbox or frame with content on it from e.g the main form to a tabpage on that same main form using code.
I can change the position of the control using it's location, but I haven't got a clue on how to move it from the main form to a tabpage, or from 1 tabpage to another.
-Is this at all possible and if so, how can it be achieved?

View 2 RepliesForm With A Tab Control That Has 18 Pages - Click On A Tab It Opens The Page And Select A Textbox On That Page
Mar 8, 2009I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.

Apr 27, 2011I have a user control that checks if a certain query string and session value are present then returns a boolean based on that, if it's true I want to set the master page.

View 17 RepliesAccess A Page Variable From User Control Placed On That Page From VB?
Dec 27, 2009I want to access a page variable from a user control placed on that page. All the solutions work in C# via casting to the page class. The problem is that this doesn't work in VB. The page class is not selectable from the Intellisense dialog. Manual typing results in the error type not defined. It is strange that C# can do this without a problem. What is the proper solution for this in VB? I had other cases where I needed to access a control on the main page. C# again uses a cast to the page class to access the control. This doesn't work in VB again. So how can I access the page class from a user control in generell?
View 5 RepliesUnable To Get Master Page Control's Value At First Page Load
May 21, 2012I am using <%@ MasterType virtualpath="~/__.Master" %> to embed my master page content into child page to access control belong to Master Page. I have one DropDownList in Master page. And I want to access its SelectedValue in my Child Page.
Problem is when page first time loads and as I am trying to access DropDownList's Selected Value by writing in child Page - "Master.DropDownList.SelectedValue". I am not able to get DropDownList's Value. Its display's Blank.
But When Page.IsPostBack I am able to get SelectedValue of that DropDownList.
Scroll An ASP.NET Page Under Control Of The Code-behind Page?
Jun 3, 2009I have an ASP.NET 3.5 page with some AJAX, some Validators and some business-rule validation done in the code-behind page (VB.NET).
The Validators set focus to the 'offending' control when an error is detected.
When a business rule is violated, I used the following code to generate some javascript "on the fly" and execute it to simulate the Winforms "MessageBox.Show" functionality:
Sub DisplayMessages()
Dim lblError As New Label
lblError.Text = "<script language='javascript'>" & Environment.NewLine & "window.alert('"
[Code]....
At the end of the "btnSave.Click" code, if everything went ok, calling that subroutine.
What I get is the page scrolling to the top and then back to where it was when the Save button was clicked.
For various reasons, 'MaintainScrollPositionOnPostback="True"' is in the Page directives at the top of the .aspx code. What I'd really like is to make that FALSE for just a moment so that the page resets at the top - again, only if everything is ok and only for this button (there are other buttons on the page that require the page to keep it's scroll position).
Asp.net - Adding To Page Control Collection From Inside A User Control?
Feb 12, 2011I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?
