Custom Menu Control With Visual Studio's IntelliSense Support For It In Markup View?

Nov 28, 2010

I am working on a custom menu control, partially as a learning exercise, and I am having trouble with Visual Studio's IntelliSense support for it in markup view.The conventional ASP.NET menu allows you to place an arbitrary depth of <asp:MenuItem/> elements under the <Items>...</Items> element. I'm after the same behaviour for my menu.Mine unfortunately does not. VS insists on an empty tag:

<hn:AwesomeMenu runat="server" ID="menu">
<Items />
</hn:AwesomeMenu>

Event Handler For The Activity Control In The Markup Of The Aspx Page?

Jun 24, 2010

I have created a web user control called Activity. I have defined a public-facing event on that web user control called OnActivityDelete. There is a delete button in the Activity control. When the delete button is clicked, the Activity control fires the OnActivityDelete event. I am using this web user control in a repeater. I assign an event handler to the OnActivityDelete event on the repeater's item data bound event. When I click the delete button for the Activity control, the event fires from the Activity control, but it never hits the event handler in the page that's using the control. (I have stepped into the code with the debugger and confirmed this behavior).

My suspicion is that this behavior has something to do with the fact that the event handlers are added in code behind when I bind the repeater to a datasource, which I only do if the page is not posting back.Is it possible to define the event handler for the Activity control in the markup of the aspx page? If so, will this solve my problem?If not, do I have to bind the repeater and hook up to the events every page load in order to solve my problem (this works, I just tested it), or is there some viewstate trick to getting the events to persist? Markup of Repeater on page:

<asp:Repeater ID="rptrActivites" runat="server" EnableViewState="true">
<ItemTemplate>
<div class="activity">[code]...

Page's code behind:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

If Not Page.IsPostBack Then
GetActivities() [code]....

Visual Studio :: Event Handler Lightning Bolt Missing?

Oct 1, 2010

I have recently upgraded from VS2008 to VS2010 after a few months away from ASP.NET coding and I am hitting a problem I never had before. I seem to remember having a lightning bolt icon in the properties window for a web form that would automatically create the skeleton event handler code for any one of a range of page events. However, I cannot see this lightning bolt anywhere in VS2010.

Feb 6, 2011

One thing I do like about visual studio is the autoindent feature in the code behind where you can essentially close off the bracket of a loop or method or class and it'll automatically indent everything to make it consistent looking.

Web Forms :: Add Event Handler To User Control And Capture Event On Parent Page?

Apr 24, 2010

Using vb.net/asp.net 2005.

I have a page books.aspx that has a control named authors.ascx.

Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.

I have to pass the authorID from the user control to the parent page.

In my authors.ascx control I just created this event:

[Code]....

Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.

Difference Between Adding Code In The PreLoad Event Handler And At The Top Of The Load Event Handler?

Oct 3, 2010

Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?

How To Generate An .NET 2.0 Retro Web.config Within Visual Studio 2010

Aug 3, 2010

I'm using VS 2010 Express Edition (VWD) to develop a website project that will be deployed to a Windows 2000 Server (targeting .NET 2.0). BACKGROUND: The website was new, so I chose the 'c# blank website' project template in VS 2010. This (as you may know) gave me an extremely more lean web.config file than VS 2008. I like that for 4.0 development, but I'm going to be deploying it to the testing region tomorrow and I'm getting concerned that all that extra stuff that used to be in the web.config is going to bite me.

Add Event Handler To Control

Jul 25, 2012

I am creating a web control by addin the html in the code behind, like this:

Code:
Dim sb As New StringBuilder
Dim myDiv As HtmlGenericControl = Me.theContainer
sb.Append("<table width='100%' cellpadding='0' cellspacing='0' style='border:0px;'>" & vbCrLf)
sb.Append(" <tr class='mainRow1'>" & vbCrLf)
sb.Append("<td align='left' style='border:0px solid white;'>Main Menu</td>" & vbCrLf)

[Code] ....

This will generate the html for the table in the codebehind then inject it into the specified DIV element. My question is, if I create a control in this manner, how do i add an event that will fire a method in my codebehind? For example, if i want to create a image button i would do it this way in the code:

Code:

<asp:ImageButton CommandArgument='<%# (Container.DataItem.objectValue) %>'
ID='ImageButton1' runat='server' OnCommand='Button1_Click' ImageUrl='~/images/folder.gif' />
but in the code behind i would do this:

Code:
sb.Append("<input type='image' name='ctl00$ContentPlaceHolder1$importWizard1$folderControl1$folderRepeater$ctl04$ImageButton" & myCounter & "'")
sb.Append(" id='ctl00_ContentPlaceHolder1_importWizard1_folderControl1_folderRepeater_ctl04_ImageButton" & myCounter & "'")
sb.Append(" src='images/folder.gif' style='border-width:0px;' />" & vbCrLf)

But I cant add the OnCommand because it wont be rendered properly.
