Get Sub To Address Appropriate Control / Can Set Its 'checked' Property Based On Text Read
Jan 2, 2012I have a form with about 48 checkboxes.I have a public sub that reads a webpage, parse the text of that site to get the values that correspond to these checkboxes.For example: one of the lines would be: "Exterior = 255", or "Street = 0".I do have check boxes that called "Exterior" and "Street". the question is how I can get my sub to address the appropriate control so I can set its "checked" property based on the text read.

Bind Property Of User Control To One Of The Parent Control's Fields?
Dec 30, 2011If I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.
View 1 Replies.net - Make A Class Property Behave Like The Checked Property On RadioButton?
Jun 1, 2012I have a very simple class that holds a few public properties - ID, Text, Colour, etc. and a Boolean called 'SelectedItem'. Just like the Checked property on RadioButtons, only one item can have its SelectedItem property set to True within a particular group. Note: there will be several separate groups (lists), each allowed to have only one item with SelectedItem = True.
My first thought was that I would probably just have to handle everything outside of the class, setting SelectedItem to False for every other item in a particular list when another item was selected. But that seems rather inelegant to me. So I've been trying to think of how this might be done within the class. For example: could I perhaps have a private string property called say "GroupName" - set in the New sub when adding a new instance of the class - and then use a private shared method to set every item's SelectedItem property to False, provided the item has the same GroupName as the newly selected item? I would have a go at doing this but I have no idea how to enumerate every instance of a class from within that class, or whether that's even possible. Is it? Or is there another (better) way to achieve my goal? Here is a cut-down version of what I've got so far:
Public Class ResourceItem
Public ID As Integer
Public Text As String[code]....
As can be seen: instead of instantiating a new ResourceItem and passing that as an argument to the manager's Add procedure, I'm simply passing the details of the new item and the procedure is creating the item from those. I don't know whether this is a good or bad idea - please advise - but I've done it because I couldn't figure out how to make the SelectedItem property only writeable by the manager, so I wanted to avoid having directly accessible objects that could have their SelectedItem property set to True without it deselecting all the other items in the same group. Of course that still leaves the possibility of setting a variable to one of the manager's list items and setting it from there, so I would still like to know how I could prevent that, if possible.
UPDATE: I didn't use the code above in the end, deciding instead to go with Cyborgx37's solution - which seems to work perfectly well for me despite the warnings about best practice. I also realised I would need to use the same class in another scenario where multiple items could be selected, so it was easy to add a Boolean property to the manager to enable that.

Display VB User Control Property In VS IDE?
Feb 4, 2011I built a VB ASP.NET 1.1 Web User Control that contains several properties. I want these properties to display in the VS2003 IDE Properties window, for easy manipulation. However, none of the properties appear! How do I make them show in the IDE?I am a C# guy, and not very familiar with VB, so this is probably a no-brainer. Here's a property, including attributes:

User Control Datatype Property?
Feb 9, 2009I'd want a text box that at design time the developer can set a datatype property so only a value matching that datatype can be entered at runtime (e.g. If we made the datatype property of a textbox an integer then the user could only enter numbers into that textbox)In additiion I need a further property to replace ".Text". .Text always holds the entered value as a string, I want the new property to contain what has been written into the textbox but as the datatype that has been selected at design time.

View 3 RepliesAsp.net - Get User Control Property After Server Transfer?
Apr 14, 2011I have a host page with multiple user controls in it. Some of these controls have a user created property named Enabled, and is boolean.In some controls the default value for Enabled is set to False. In the host page, I am able to access the property and set it to True. The control does what it is supposed to.On this host page there is a "Run Report" button which executes a Server.Transfer to a "Results" page.In the codebehind of the results page, control values from the PreviousPage are checked via other user created Properties for the controls and added to a ParamterList.
I am attempting to check the Enabled property of the controls on the PreviousPage, however when this is done, it appears that the Enabled property is set to that of the default (in this case False), and not what I had set it to on the page when it loaded.Does the value of this property need to be put into a hidden text box or something so its value is available after the ServerTransfer? It seems like any control which contains a value is retrievable via the PreviousPage and its user created property, but any variable set inside of the control is reset back to its default value.

Error While Setting The Property In User Control
Feb 20, 2012I am using a user control using vb.net. It include the program to retrieve the values from database while giving the paramers. When I set the property from my main program i am getting an error "Invalid attempt to call Read when reader is closed." When i gone to the online help i got the message as follows "System.InvalidOperationException (.NET Framework 4)The exception that is thrown when a method call is invalid for the object's current state. InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments. For example, InvalidOperationException is thrown by IEnumerator.MoveNext if objects of a collection are modified after the enumerator is created, or ResourceSet.GetString if the resource set is closed before the method call is made. If the method invocation failure is due to invalid arguments, then ArgumentException or one of its derived classes, ArgumentNullException or ArgumentOutOfRangeException, should be thrown instead.[code]

Setting Default Property Value In User Control?
Aug 24, 2010I am creating a customised version of the ListView control and there are several of the properties that a ListView has that I would like to be set to a different value to the ListView default when a user goes to use my user control.
From what I've found there seems to be a number of people suggesting just set them in the constructor, but to the best of my knowledge that would just mean that the user would not be able to change the properties in the PropertyGrid in the VS IDE.I assume this is probably something extremely simple that I have overlooked.

View 2 RepliesSet A Property Of A User Control From Repeater Databound Data?
Mar 28, 2011I have a user control inside of a repeater that is being bound by a sqldatasource. I get the following error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. EDIT: NEVERMIND Egg on my face. I was getting this databind error because I was binding it somewhere else in an effort to troubleshoot my real problem from last friday but I forgot about it.
WHAT MY REAL PROBLEM IS: The usercontrol is getting bound before the properties get set so it appears as if they are never set. When stepping through I see that they get on the property is hit before the set on the property is hit. For example if I put <%# EVal("Address_ID") %> before the user control I will see the ID displayed but then the user control will display an emptydatatemplate because it is being passed the ID of 0.

Strategy To Override Enabled Property Of A User Control?
Aug 5, 2009I have a usercontrol with a picturebox and a few buttons related to it, such as LoadFromFile, Paste and Zoom (that last one pops up a new form). Is there a way to override the basic Enabled property of the usercontrol so that I can keep the Zoom button active all the time, while turning off the other buttons?
I realize there are 2 "obvious" replies. don't do Enabled=False, create a custom method. do everything in the one form, not a usercontrol, so you can pick and choose disabling. Both are less than ideal, given that I'm putting this control into a couple of existing forms, so I'd like to work around how those forms already behave. So is there a way to override the behavior of my usercontrol when it gets disabled? What would be my best strategy?

VS 2010 User Control Property - Group Attributes?
Apr 2, 2010this questions has be answered partially, but I can't find any full tutorial for this problem.I created my own user control (an advanced list with columns). Each column has different attributes like width, colour and text.I want to able to add this user control onto a form and select/edit the different attributes of each column. Hence, for each column in my user control (these columns are created beforehand, no columns can be added or removed from it) there should be a property in the property-menu. Each of these column-properties should be expanded (like the normal size-property in most default vb-controls that can be expanded with the little plus to show the width and height individually.What i mean by this, is: In the property-menu there should be attributes like Column1, Column2, Column3. Each of these attributes should be expanded to show the attributes like width or colour.
Currently I have different properties for different values of the same column, like Column1Wodth, Column1Colour, etc, but I want to group this under one value Column1.I think this is quite an easy solution, but forgive me, I spent more than 4 hours on google, but couldn't find a proper solution.
Building Custom User Control - Default Property Of Class?
Jan 22, 2012If we say blue is the default colour of the Backcolor property I understand it as if you don't specify a colour for Backcolor blue will be its colour.
