Call Button Event From One User Control To Another?
Oct 28, 2011I have created two user controls (lets say A and B) and calling then on default.aspx. Both user controls have button named as clear and its event method "btn_clear_click (sender,event)". Actually I like to do something like this: if I click clear button of user control A then it would also do the same tasks defined in user control B's bth_clear_click method. Means, is there any why to call button event of one user control in another user control.

From HTML Content In A WebBrowser Control, Call Another Control?
Feb 20, 2010I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?
View 3 RepliesAccess User Control Attributes From A User Control?
Mar 27, 2009I 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.

Call A CLR User Defined Function Within The Assembly
Feb 14, 2012The main function receives data, uses additional functions to calculates the result and gives it back. But at one point, the function needs data from the SQL Server. I wrote a second UDF, made it visible and deployed it to the SQL Server. I see now two functions under > programmability > functions > scalar value functions:
1. The main function (IsCalcDay) and
2. The function with the data access (IsHoliday)
If I call directly the second function from VST in the debug mode, it works fine, bur if I call it via the main function, the code stops if the connection will be opened. The error is "Data access in this context is not permitted. The context is a function or method that is not marked with DataAccessKind.Read SystemDataAccessKind.Read or a callback to retrieve data from the FillRow method of a table-valued function or a UDT validation method." (translatet from German, probably slightly differnt in English)
VST (2010 prof) and the SQL Server (2008 R2) are running in my virtual W7 maschine.
Here is the code of the second function:
Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
[Code]....
Why can I open the connection if I call the function directly, but it fails if the function is called from another function?
Auto-fill A User Input Control With The User's Windows?
Feb 11, 2011I am creating a form for work where managers can report when they find a customer's personal information laying around on a desk (we work at a call center where agents answer calls for a wireless cell phone provider, so we take personal information security very seriously). Anyway, I am wondering if there is a way to have a text box autofill with that manager's windows username (since they will need to be logged into their own profile to use the form).

How To Call A Button Or Other Control By Name
Apr 29, 2010Rank beginner here. Please be patient. I have buttons on my form. I can programmatically alter their properties:
btn00.BackgroundImage = Image.FromFile(sGrid(0, 0))btn00.BackgroundImageLayout = ImageLayout.Stretch
So far so good, but how do I refer to a button without its name. For example, is there a Me function (or something similar) like there is for forms, so I could do something like me.backgroundImage=ImageFromFile(sGrid(0,0))

Make Assembly FULLY Trusted - Use The Web Browser Control In User Control
Dec 19, 2009I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!

View 12 RepliesAsp.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?
