I have a vb.net asp application where I'm loading a control (from another control on a page). I want to set a variable between the two controls when it loads. This is where I load the control:
[Code]...
In my ASP.NET Web Forms I would like to get the DataNavigateUrlFields from the HyperLinkField control.
In order to get the control I use the following code in the RowDataBound event:
If e.Row.Cells(n).Controls(0).GetType().ToString() = "System.Web.UI.WebControls.HyperLink" Then
Dim linkDownload As HyperLink = DirectCast(e.Row.Cells(n).Controls(0), HyperLink)
[Code]....
Is there any way to get the DataNavigateUrlFields property? In case there is not, is there any function to extract the downloadGuid value from HyperLink.NavigateUrl (in short treating the NavigateUrl as a QueryString)?
I have included a Date and Time Picker Control in oen of my MS Access Forms and want to set its value on the form open event. However, when I try to set the Value property I get the following error message :

I searched on the forum / Internet for the solution how a PropetryInfo object (of a Public property) can reveal if it has a Private Protected Setter ... it was all in vain .... all help I found was about how to "Set" value of a public property having a Private Setter.I would like to know if I have a PropertyInfo object of a public property, how would I know if its Setter is Non Public?
I tried, in a exception handling block, where I did a GetValue of the PropertyInfo object and then called SetValue by setting the same value back... but to my surprise it worked well and didn error out.

At the moment i'm working hard to better understand aspnet (VB), still learning and still enjoying, but at the moment i'm struggling with (i think something realy easy) but can't find out how to fix it,what i need to do is: assign the propperty Weekday() of CSlot Dim CSlot As New timeslotParamTO I have to assign te propperty weekday to Cslot but the propperty must be 1 or more items from the Public Enum WeekdayEnum. i just can't figure out how to assign 1 or more weekday's to CSlot.weekday().

What is a public read only property?If you're not living on the edge, you're taking up too much room
View 2 RepliesWhat is the purpose of Public property? why would i do this instead of just doing Public abc as string? [code] Because you may want to do data validation on it before assigning the value to the Private variable. Because you might want to raise an event when the value in the Private variable changes. Because you might later want to make it a ReadOnly property.

is there a way to have the Get part of a property available as public, but keep the set as private?Otherwise I am thinking I need two properties or a property and a method, just figured this would be cleaner.

One of my ASP.NET websites makes use of the CultureInfo class to format currency values and normally this works fine. However, some new code is causing some unexpected problems. In the code sample shown below, txtBox1 correctly displays £99.00 while the line that specifies a value for txtBox2 generates the following error,Too many arguments to 'Public ReadOnly Default Property Chars(index As Integer) As Char'.The key difference in the txtBox2 value is that it is derived from a SQL Server database reference using Linq-to-SQL (CurrentUKFees.Print1). The relevant database value is the integer 8 and I was expecting txtBox2 to show £8.00. If I delete the CultureInfo code then txtBox2 correctly shows the value '8' without any currency formatting.[code]
View 1 RepliesDuring a code review I looked at set of repository classes (in vb.net). I am used to seeing these repository classes full of functions that return collections (among other things) of your domain objects. However, this repository had 1 public property and 1 private variable that looked something like this:
Private _item as Collection (of Customer)
Public Item as Collection (of Customer)
Get...
Set...
In the "Get", there is code that gets a the Customers from the DAL and loads it in the private _item. What would the benefits be in using a property (customerRepository.Item) instead of plain old function (customerRepository.GetAllCustomers)? The "Property" way looks odd to me but odd doesn't always mean wrong.

View 2 RepliesSo I've run into a case where I have a class that can store either a string or a numeric value, and I want a single property to return one or the other (it would be a failure for both to be set). I'm using a custom generic class to deal with the numerics (so I can use signed, unsigned, and nullables), and will be storing the string in a separate variable.
In theory, if overloading could be done based on the return type, I could do this quite easily. But .NET currently disallows this. So I am wondering if there is some other really-far-out-there trick (outside of MSIL generation via Reflection.Emit) that could accomplish the same thing.
I'm open to ideas via delegates, pointer dereferencing, generics, mystical rites, etc. Also interested in any thoughts or pros/cons of such possibilities as a learning tool. If using a standard Object is the only way to achieve what I want, then that's fine with me. But It's difficult to find the correct set of keywords to hunt down this kind of capability on Google, so I thought I'd ask here before I moved on to doing something else on the project.
