Removing Dynamic Controls

when i post back and my pages calls LoadViewState(object) and then calls "CreateChildControls" how can i handle removing controls if that value of what control i should remove does not get set in the viewstate until the click event of my button???? which means i wont have the value of the removed control until it post back again....which will leave me with having to click my delete button twice to remove the control from the page...any help on how to firgure this out??

What you need to do is Get rid of CreateChildControls because u need to update your view state before your UI will reflect the changes.....Next u should get the id of the control that is calling this event in the button CLick event or where ever like so

    public void btnDelete_Click(object sender, System.EventArgs e)
    {
        NumberOfControls -= 1;
        RemoveControl(sender);
    }
 
update the viewstate property then pass the sender down to another method in which will remove your controls from the list like so
     public void RemoveControl(object ControltoRemove)
    {

        Button deleteButton = (Button)ControltoRemove;
        string ClientID = deleteButton.ClientID;
        ClientID = ClientID.Replace("WucTimeWorkedGrid0_", String.Empty);
        ClientID = ClientID.Replace("_btnDelete", String.Empty);

        Control crtl = (Control)UiTimeWorkedContainter.FindControl(ClientID);
        if (crtl != null)
        {
            int index = UiTimeWorkedContainter.Controls.IndexOf(crtl);
           UiTimeWorkedContainter.Controls.Remove(crtl);
           if (index >= UiTimeWorkedContainter.Controls.Count)
           {
               index = index - 1;
               UiTimeWorkedContainter.Controls.RemoveAt(index);
               crtl.Visible = false;
           }
           else
           {
               UiTimeWorkedContainter.Controls.RemoveAt(index);
               crtl.Visible = false;
           }
        }
    }
 And that is how u can remove Dynamic controls and have them be refelcted in the UI when the delete button is clicked.....thanks...HAPPY CODING!!!

Dynamic Slave Controls
I am working a solution to enhance slave controls. I have created a proof of concept based on the 2.04 code base that shows how to load slave controls without switching to the admin view. I have included a sample module that contains 3 view controls. Each control has a row of buttons that can be used to load one of the other 2 controls. (and no I am not using panels.) The default control has a drop down of other instances of the dynamic control that exist on the current tab. Using the module communicator you can raise an event from one control that tells another instance of the module what c...

Usercontrol vs Custom Server Controls, Any need for Custom Server Controls
Hello I'm new to ASP.Net so this is probably a stupid question but, is there any need to create customer server controls now that you can pre-compile usercontrols into a dll and thus easily share between applications? This blog post from David Ebb describes how to do it and the restrictions he note don't seem that bad (other than being able to embed resources such as images in the dll). http://blogs.msdn.com/davidebb/archive/2005/10/30/487160.aspx His article desribes the techniques for ASP.Net 2.0 and he suggests that there will be further improvements in .Net 3.5 in this ar...

how to have both server controls and html controls rendered in a custom control?
I have a custom control in which there is an html text box.when you click on it , a div containing a table is appeared and according to what you select in that table a text is set to the text box. It works fine but the problem is: as the text box is an html element it doesn't have viewstate and when a post back occures in the page its value disappeares.I tried a hidden field to keep its value.again there is another problem : I put this custom control in a usercontrol and put the usercontrol in a multiview and by clicking on a button this view is selected and by clicking another bu...

Custom Server Control Vs Web Parts, Any need for Custom Server Control
Hello I've just posted a similar question on why you need server controls when you can pre-compile usercontrols and redistribute them. http://forums.asp.net/p/1397433/3010100.aspx#3010100 I've seen lots of (usercontrol vs web part) but not much on web part vs custom server control. According to the MSDN site you can put web parts onto a normal asp.net page outside of a web part zone and they behave just like custom server controls. So, if you are creating a bunch of controls for redistribution to customer asp.net sites and/or SharePoint sites why don't you just create Web Par...

problems listenening to events on a custom server control from another custom server control
 Hi all,I am having problems listening to events on one of custom server controls(AddBookmark) from another custom server control(BookmarkList). The listener or the BookmarkList control has a property that can be set to the AddBookmark control (string at design but the reference is obtained at run-time). I am able to get a reference to the AddBookmark control and add a listener to it on the BookmarkList control on the OnPrender of BookmarkList. But the problem is that when the events on AddBookmark gets fired, the listener added from the BookmarkList is no longer present and the listene...

Dynamically Loaded User Control inside Custom Server Control Weirdness
Hello, I have a wizard controller server control that walks the steps of a wizard and dynamically loads the user control to display for the wizard page using Page.LoadControl. Everything is working great! Until this showed up. One of the controls on the user control is another custom server control. This server control on the dynamically loaded user control makes use of RegisterClientScriptBlock. For some reason, the client side code for RegisterClientScriptBlock never gets rendered! I stepped through the code to ensure that RegisterClientScriptBlock gets called, it does. If I ...

Why can't I add controls dynamically to my customer server control?
This is a simple example of a custom control where I dynamically add a new control to the hierarchy. The problem is when I click the 'C' button, it adds the B button and then the next click of the 'C' button will hit the B_Click event handler. My only theory is that since it was added to the middle of the control heirarchy, then event handling got confused. Has anyone seen this problem or am I doing something wrong? using System; using System.Configuration; using System.Collections; using System.Text.RegularExpressions; using System.Xml; using System.Data; using S...

Dynamic custom control on custom control
What I'm trying to do is create a module for use within a larger page.  The page itself is an order form, which will have typical payment info (address, credit card, etc.), and the ability to select what you are paying for.  Our clients will have several options in how they want the page setup.  They can either have a single form, or they can have each module on it's own page.  They can also have all the selected items fire in a single transaction, or have a seperate transaction for each item selected.  And they can limit the total number of transactions a person can...

Custom Control within a Control Control
I am developing a custom controls that will render headers for different web sites. Within these controls, I want to place another custom control that will change the language. I created the language control and had it implement IPostBackDataHandler. This control works fine if I drag it on a new web form, but if I tell a header custom control to render it problems occur. The Language Selector custom control does not have a Page member anymore and the event handlers do not work. Does anyone have any experience with doing something similiar? Anyone have any suggestions? Thanks, ...

Custom Server Control With Child Control
All, I am currently putting together a very simple control. The new control outputs a table with two rows. The top row contains a heading and the bottom row will contain any other content. The control as it stands works perfectly well and I can place text into the content row no problem. Now, to the problem. Once I'd completed the control I figured it would be neat to enable the developer to add controls directly into the bottom row (content row) of the outputted table. As you probably know the WebControl class has a Controls collection which the developer can use to add any other...
