View 12 RepliesI have a user control which contains some textboxes,buttons ,labels and comboboxes . I used that control in a form and inside a split contaier.Splitter can be moved by the user. User control is docked as fill.
Now when user move the splitter the user control size is changes as it is dock fill but the inner controls used in that user control looks like fixed in a single place .It are not moving nor resizing .How to do this .Is there any property to perform thisI already know about anchor property but sometimes it causes overlapping of controls so I can not use it.

View 2 RepliesI have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:

...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.
I have UC that inherits a textbox. It is meant to only accept numeric values. I want to be able to add a property to give the end user the choice of setting the FORETCOLOR to another color other than that which they have chosen for the normal FORETCOLOR settings. Is there some line of code that will allow me to access FONTCOLOR dialog box when a user clicks the FORECOLORNEGATIVE property setting in the Properties settings?
View 6 RepliesIn order to take advantage of the spell checking ability of WPF textboxes, I have added one to a user control (with the use of elementhost). This user control is used in various window forms. My current problem is trying to handle keyup events from this textbox but the windows form is unable to "get" any event from the control. I can access the properties of the textbox just fine (i.e. text, length, etc.) but keyboard events don't seem to work.I have found, however, that the following will bring back events from the WPF textbox:
Public Class MyUserControl
Private _elementHost As New ElementHost
Private _wpfTextbox As New System.Windows.Controls.Textbox

The user control is now able to do something after the PreviewKeyUp event is fired in the WPF textbox. Now, I'm not completely sure how to have the window form containing this user control to work with this.
In a user control I have the code shown below.
I now realize that it is incorrect because the container's InitializeComponent property initializations have not run yet and they must be run prior to Refresh being called.
How (where) can I run Refreash after the container has initialized this user control.[cod]e...

Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. Like measuring the time since the last textchange event and if it was > than a certain value then it would proceed to run the rest of my procedures.
Language: VB.NET
Framework: .Net 2.0
I've created a user control with a simple text box and a corresponding label and added a few custom control properties. When added to a form, I'm trying to loop through all control of this type and evaluate the custom property. In the below, the cntl.MyCustomProperty is not recognized. I can evaluate the property when I check each user control on the form by name, but not by using the loop below. I would much rather use the loop as it is much cleaner.
For Each cntl As Control In Me.Controls
If (TypeOf cntl Is MyUserControl) And cntl.MyCustomProperty = "ABC" Then
''Do some stuff
End If

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.

I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!

Can a usercontrol inherate an application defined class ie.. could you inheritance a classic rect class into a user control to add the hight and width properties to the control without having to do all the coding all over again? Currently I just declair a private instance of the class within the control and then encapsalate. It would be nice if I could just inherit all the functionality of my classes into controls designed to implament the classes.

View 5 RepliesI have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?
If 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.
