View 10 RepliesWeb Forms :: What Is Difference Between Panel's Visible - True / False And Setting Multiview's ActiveViewIndex
Sep 8, 2010I 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 ?

View 1 RepliesWeb Forms :: Binding Visible Attribute On Button?
Jan 14, 2011I'm having some problems. I am trying to bind the visible attribute of a button, to a boolean in my code-behind, and it is not working as intended.
When i put a breakpoint on the boolean, i can see it is ONLY visited, when it is true. In the cases where it is false, it is never questioned, and it apparently defaults to true (dunno why).
In essence, i have a querystring called "dep". If it is not the same as the department the user is in (retrieved from AD), the boolean will return false.
So, i assume i am doing something wrong here. Here's my code.

Forms Data Controls :: FormView, AllowPaging=true, And AutoPostBack=true?
Feb 24, 2010It took me a little while to figure this out, but the AllowPaging="true" on the FormView seems to be the culprit. I don't have much experience paging from a FormView, but for this requirement the customers wants this kind of UI.I have a FormView with DefaultMode="Edit", which is bound to an EntityDataSource. One of the entity's properties, "ExternalID", determines whether some of the other properties in the entity are read-only. For example, if IsExternal==null, the FirstName, LastName, and Email fields should be rendered as TextBoxes. If IsExternal!=null, the 3 properties should be rendered in Label controls.
