View 1 RepliesBind A WinForms TreeView Control To Some User-defined Objects?
Oct 16, 2011I'm trying to bind a WinForms TreeView control to some user-defined objects. In particular, I'd like to bind aTreeNode.Text property to myObject.Name. My strategy is to create xTreeNode, a subclass of TreeNode, add a DataBindings collection, and expose its Text property. This would allow me to write some code like this:

Asp.net - Pass A Variable To User Control To Determine Display?
Nov 28, 2011I've found various C# examples here, but I can't seem to get a VB version working.I want to be able to pass a simple variable into a User Control to determine whether it shows a certain section of data.It's basically a Customer Data form, and in some circumstances I need to show a line with the customers account number and sort code, and in some I don't, so my user control:
<controls:customerForm ID='customerForm' showBankDetails="no" runat='server' />
But I can't work out what to do with the showBankDetails variable in Code Behind to stop it from rendering that section, or simply hide it with a CSS snippet.How do I access that variable in the code behind using VB.NET?

VS 2008 Determine If User Has Scrolled To The Bottom Of A Control?
Aug 22, 2010I am modifying some code I found here to test to see if a user has scrolled to the end of the control. In this case the control is a Crystal Viewer but I posted here because I think the issue is based on the vertical scrollbar not the Crystal Viewer itself.
The code flags an error at
Me.CRViewer.Controls.OfType
Indicating 'OfType' is not a member of 'System.Windows.Forms.Control.ControlCollection'.
I understand the concept that I can't reference something that it is not but I don't know how to fix it. The original code was for a DataGridView.
The ultimate goal (not finished) is to find out when the user has used the mouse or possibly the scroll bar itself and if it hits the bottom of the page of the viewer, then trigger a new page so it looks like they can just keep using the mouse to scroll.
Public Sub New()
Me.InitializeComponent()
Dim vscroll As VScrollBar = Me.CRViewer.Controls.OfType(Of VScrollBar)

View 1 RepliesDetermine Which Control Called A Form?
Mar 3, 2010I have three buttons on my main form, say Form1. Clicking any of the buttons brings up Form2 modally for input, it's a number pad. Now, depending on which button was clicked to get there, after the user enters his numbers, I need to change a specific label on Form1. In other words, btn1 clicked puts user input into lbl1 and so on... I could probably do this with a variable but wondering if there is a more elegant way.

Asp.net - Getting Form Field Names On Submit When Form Is User Control
Jan 30, 2009I've created the beginnings of my new web application, but I am often coming up against the issue that ASP.NET renames elements IDs or in the case of form fields, their names.I have a form which is basically a sales system. It is essentially made up of two User Controls, one is a form for Customer Details (name, address etc) and the second is a form for the customer's purchases, it consists of a number lines dynamically created by Javascript created as you list the items the customer is purchasing. Both these sections are User Controls because they are to be used for other areas of the system where this data will need to be recalled/re-entered.When the USer Control is loaded, the field which contains the Customers' Name is renamed "m$mainContent$customerForm$name" I understand where this comes from, "m" is the ID of my Master Page, "mainContent" is the main Content Placeholder and "customerForm" is the name of the User Control.
In fact, in my case, this will always remain the same on all forms, so it is relative easy to overcome... but... suppose it wasn'tI can see there are ways I could deal with this with Javascript, but the form doesn't need an AJAX submit, a normal Post will do fine for this, so when I open up the recieving page I want to call Request.Form("name")% to save the customer's name into the database, but of course I really need Request.Form("m$mainContent$customerForm $name")%How would I dynamically extract those prefixes from the posting form to ensure that if I rename anything or use it in a different scenario, the problem will not break it?I am using .NET 2.0, so can't use Static Client.

View 2 RepliesUser Control Accessing A Form Within The Project?
May 1, 2010I have a "windows form" user control--that is, not on a web page etc. This user control has a form within the user control project. However, code from within the user control can't 'see' the form even though it is a public class---I don't understand why this is the case.
So how can I access the controls (a couple of radio buttons) on the form from code within the user control? I tried creating public properties on the form to return the state of the radiobuttons, but this still doesn't work. I get a "Reference to a non-shared member requires an object reference." error
Should I not be able to see the form since it is a public class?
