Web Forms :: What Is Difference Between Panel's Visible - True / False And Setting Multiview's ActiveViewIndex
Sep 8, 2010
I have a panel that contains several controls.
On the other hand i have a MultiView that contains Several view that in turn itself contains several controls .
In multiview we have to set ActiveViewIndex for the view which we want to see.
That same thing can be done through Panel containing another seleral panel's and setting its Visible property to True/False accordingly.
Is seems Multiview is just using this Visible property internally to render controls .Since other views (whose Index is not set to be active Index) are processed on the server for its Whole life cycle(I am confused here..whether i am right or not) .Same thing perhaps happen when we use a Panel insteed and use Visible=True/False. So, what is the difference between MultiView and Panel taking this scenario ?
I have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?

Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:

In my database I have boolean column to declare if something is 'active'. In my web application I would only like one item to be able to have the 'active' status at once.
Therefore I have a radio button list in my aspx page to force the user to select one item. I know it is easy to set the selected item to true through my SQL update statement, but how do I automatically set everything else back to false/null!?
I have a Panel that I'm setting visible=true explicitly. The debugger passes over that line and visible still evaluates to False on the next line. Obviously as a result, the Panel is not shown. How is this possible?

I have a web page that I have a media control player on along with other controls in a table.It's a training video, so the controls are not visible.So the user can advance to the next web page,I thought I would have a button control inside an update panel with a time control so that the user had to watch the video and then the button control would appear after the video completed.I'm setting the button update panel to NOT visible and then turning it one when the time control elapses the same amount of time that the video runs.My problem is that when I set the visible property of the update panel to NOT visible it also makes the media player's panel NOT visible too.They are in two different panels.The medial player in a standard panel and the timer control connected witha separate panel that contains the button for the user to proceed. When I set the visible property to "true" the media player runs but the update panel with the button is visible also.

In the postback option class, the autopostback property is not functioning (for true or false) to forcibly set the the post back event on web page load as defined at the MSDN Url http://msdn.microsoft.com/en-us/library/system.web.ui.postbackoptions.aspx
A client side validation retrieves the GetPostBackEvent reference successully but fails to to load the page as a forced post back event. The options being set are a) ActionURL, Autpostback , RequiresJavaScriptProtocol and perform validation.
So when i select "Yes" from the first drop down, the "hiddenDetail" label becomes visible and when i select "No" from q1 the "hiddenDetail" label becomes invisible.The problem is that because i am using AutoPostBack when you select "No" the "hiddenDetail" loses its children (i.e. the label inside it) which is obvious why but i am wondering, is there anyway i can make the "hiddenDetail" invisible (sort of like display:none in style) in VB without losing its children. Or is my only option to work with this in
I have an asp:label field for and expire date that should either display "Never" if the database field ([msDS-UserDontExpirePassword] this is a bit - true/false - field) is True, or otherwise display a date (pwdExpireDate).
My code doesn't throw any errors but I can' fully test it without putting it into production. Can someone tell me if this is correct? Also, there is no code-behind and I can't use code behind for this.
