View 1 RepliesIf 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 RepliesI have a user control that is created within a tab control every time a user creates a new tab, so each tab on a tab control contains a new instance of the user control. From within the user control I would like to get the parent tab's index, so that I can dynamically alter properties of the tab, such as the tab's title.
View 17 RepliesTrying to access a property from the parent page on my user control.
Here's the start of my default.asp codebehind:
Partial Class _Default
Inherits System.Web.UI.Page
Private _selectedID As String = "74251BK3232"
[Code].....
I'm getting the error "selectedID is not a member of System.Web.UI.Page"
I have an ASP.NET page (WebForm) on which I set the content of a central DIV by dynamically loading one of five user controls during Page_Load, dependant on the stage of the application.
One of the user controls contains radio buttons and a text box together with a submit button. What I want to do is process that information when the form is posted using the submit button.
I could do this with an AJAX call using jQuery, but I don't really want to do that, so I'm trying to access the form data on postback, but on page load following the postback the data is not present in the Request.Form object.
Looking at what I need to do it seems pretty simple and I'm sure is once you've got your head around it, but I can't find out how to carry this out. Some of the things I have read refer to event bubbling, but that doesn't make too much sense in this scenario.
EDIT: To clarify, I want to post the page back to itself to capture the values from the form elements via the Request object, store them in the database, and then display a confirmation message (or something else) on postback, and not re-display the same control again. So I won't be loading the same user control again.
I have a simple user control which wraps some logic around an AutoCompleteBox. This question could apply to any ItemsControl control like a dropdown or listbox though.
<UserControl>
<Grid Background="White">
<sdk:AutoCompleteBox Name="myACB" ItemsSource="{Binding myData}" />

Here is the pertinent part of my code:
Public Class Form1
Inherits System.Windows.Forms.Form
Private Sub MenuItem3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

I have a user control that has several things on it. One is a grid that I want to show pass the bounds of the user control. I want to use the form that is using the user control boundries. How do I do this? I hope this is making some sense. Do I have to set a parent or childeren?
View 2 RepliesWe were using the parent's FormClosing event handler to get user confirmation of the exit before continuing, but have just discovered that the child windows get closed before this is run. We only want a single confirmation message box, but I guess that would require the child windows to ask the parent to confirm.
View 1 RepliesUsing MDI in .net, how do you reference a control on a parent form from a child? Like, if on the parent I have a textbox called txtBox1, what could I do from the child form to read the contents? I've been googling unsuccessfully all day. The closest I've found is
Parent!ControlName.Property
I don't know what the ! is supposed to mean, but I get an error here: Class 'System.Windows.Forms.Control' cannot be indexed because it has no default property.

View 2 RepliesI have a problem I am trying to set the parent textbox from the modal popup.
Although I found the control from the modal popup with the below code
DirectCast(Parent.Page.Form.FindControl("ContentPlaceHolder1").FindControl("myAccordion").FindControl("txtTo"), TextBox).Text = str
This is being called on button click when the user has finished selecting from the Checkboxlist.
When the parent page is shown again though the textbox is empty.
The scenario of my user control is that a user is to select from a checkbox list which is a list of emails.
When done has been clicked then it is required that the selected emails be forwarded to the parent webpage.
Then the To Textbox in this case will be filled with the emails that the user has selected.
I would like to know if there is some simple code to release a child control from it's parent control, without having to name the parent control. In pseudocode, I'm looking for something like this:

I'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 Repliesi frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?

View 1 RepliesI am using Visual Basic .Net 2005 professional.From what I understand, I should be disposing of any object that is an unmanaged resource. I understand the best way to tell if a resource is unmanaged is if it has a Dispose method. ie: If I type a dot after my object, intellisense shows .Dispose() as one of the options. If it does, it's an unmanaged resource. Is that correct? In that case, pretty much every control is an unmanaged resource: buttons, forms, panels, etc.In the application I am working on I use an MDIparent container form, which contains MDI children forms, which themselves contain Panels, Menus, Groupboxes, etc, which in turn contain Buttons, Textboxes, Labels, Dropdowns, etc.Do I have to dispose of each button, textbox, label and dropdown within a panel before disposing of the panel?
Do I have to dispose of each panel, menu, and groupbox before disposing of the MDI child form?.Or can I just call the Dispose() method of the MDIchild form and the GarbageCollector will take care of all the controls and resources within the form?Watching the "mem usage" in Windows Task Manager seems to be an unreliable way to detect if I have a memory leak. The numbers just keep climbing and falling (mostly climbing) erratically and without any activity performed on the application. Is there some (relatively) easy way to detect leaks?
