Placing The Same ASP.NET Control In Different Areas Of A Page?
Feb 4, 2010
I have some code that I've inherited, and it's not the greatest in the world, but it works, with one small exception:
This page is a directory search, it has controls identified by record ID, however there exists a situation where there can be more than one result with the same record ID, thus making .NET barf. I had originally implemented a check that just didn't put the control on the page, if it was already there, but we've been getting negative feedback.
My question is this: Is there a way to put the same control in two places at once, for instance having if a user checks one, the corresponding one checks as well? I'm not terribly well versed in how .NET behaves, but I'll try to provide as much additional context as possible, if needed.
EDIT: Here's the updated code that generates the controls by looping over a datatable of results
Dim cbxSendInfo As CheckBox
Dim strCheckboxID As String = "cbxSendInfo-" & drOrganizer("ID") & "-" & i
Debug.text = Debug.text & " Loading Checkbox (" &
[Code]....
Where drOrganizer("ID") is the record ID, and i is the result record number.
I know this is a terrible way to do this, at least from my background, but like I said, this is inherited code that's been hacked to pieces.

i have an Ajax ActionLink which normally just returns a PartialView (which is just a UserControl ascx file) however, my needs have changed and i want to return another PartialView (so a total of two PartialViews) that occupy different areas of my page... of course i can't call " return PartialView("UserControl.ascx") " twice in a row consecutivelly... so my question is what would be an elegant work around for this?
how can i return two PartialViews WITHOUT wrapping these two PartialViews up in a larger parent view? i hesitate to do this because both items are in a different part of the html table which would require me to include practically the entire page in the parent view due to the structure of the table, and in this case lots of html data unnecessarily would be sent to the browser at each request - defeating the purpose of an ajax call/partial update (correct me if i'm wrong).

I have been trying for ages to put an ActiveX control on a windows form for a CCTV camera I am using. I have registered the control with windows, added it as a reference to my VS2008 project and now it appears in the toolbox.When I put the ActiveX control on the form I always get an error saying "Failed to create back buffer surface" The control is added to the form however I can not get it to work and I suspect it has something to do with this error.I have an example project from the developers of the camera that does not have this problem, i.e. I can add the ActiveX control with no problems, however the program is in C++ and I am using VB.Net.Is there anything else I need to do to stop this error from occurring?I am using a CCTV camera from Zavio (F521E). The ActiveX control is called AxVideoView.ocx.

I 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.

I 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. The page is throwing an Object reference exception when it tries to call the method EditUser1.UserAuthorization(). Why is this happening? I imagine that the method doesn't exist at that point in the stack. Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit

I 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?

But When Page.IsPostBack I am able to get SelectedValue of that DropDownList.

I 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).

I 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?

I'm currently in a programing class for vb.net. It's my first true exposure to OOP and I'm looking for some advice on areas where I could improve. I was wondering if someone would be willing to look at one of my programs that I have written and offer advice on areas where I can improve and things that I made much more complicated than they need to be. I'm not looking for a line by line critique just a general look at things to improve upon in the future.

[URL] In my Windows Form, I wanted the user to give an option to draw all over the form. But, if the user while drawing, enters the region 1, I want to assign a value to variable, say a=1. Correspondingly, if the user without leaving the mouse button previously enter the region 4, I want to b=1.After the user leaves the mouse button, I wanted to compare a and b. If both of them are equal, then Result=Done else not.

I'm writing a small program that loads a folders contained file names into a list box, you then double click one of the file names listed and it appears within the programs text area where the user may freely edit it. I then have given the users options to export the data contained within the text box to a word template. What I'd like to do is add a button which the user can click in order to strip away all the html within the text areas content. I found a solution but for some reason I can't make it work. There are no errors displaying nor does the program crash out, it simply isn't doing what it should be doing.
The function I'm using is below:
Function stripHTML(ByVal strHTML)
'Strips the HTML tags from strHTML using split and join
'Ensure that strHTML contains something
If len(strHTML) = 0 Then
stripHTML = strHTML
[Code] .....
I've used the below snippet in an attempt to put the function to work in the text box.
Private Sub btnHTMLstrip_click()
' calls function stripHTML, applies to text box
richTxtBox.Text = stripHTML(richTxtBox.Text)
End Sub
So, its not working as it should?

To reduce the size of some images I have, I'd like to remove the white padding that some have. The idea would be that if one has large white areas on the borders, then those can be cropped to save some space.

I have a table which contains the start date and end date, in my db. What I currently do is simply display both the fields in a ListView control. But instead of that approach, I'm thinking about displaying a 'clock' image and shading those areas with some color. This is similar to a Pie Chart. But the only difference is, I'm going to display a clock's image as background and the shading is based on the time.
