Visual Studio :: Generate The Event Handler Of A Control Directly In The Markup View ?
Sep 14, 2010I was wondering if there is a way to generate the event handler of a control directly in the markup view and not in the design view.

View 6 RepliesI 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>

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]....
How can I set 'View Markup' (Source code) as the default when opening a content file in VS 2008? Currently it opens in Design mode which takes ages to load, and I never use it anyway.
View 1 RepliesI 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.
View 9 RepliesWhy is VS2010 reformatting my markup?For example, I created a table with two columns and about 15 rows in the markup window, with text controls ,etc, and when i came back to the page, it had reformatted all the code for ther table into a single line????
I try to indent my <TR> and <TD> for readablility but VS2010 is messing it all up!!! Why wont is just leave it how i format it?
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.

I understand I need to load my dynmaic control on every postback and preferrably in Page_Init(). But my dyanmic controls are loaded from a dropdownlist selectedindexchanged event handler. Now after any postback, my dynamic controls are gone. How would I force it to load on every postback ?

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.
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?
View 2 RepliesI came across this site and like the top nav menu [URL] can visual studio 2008 generate such a menu like that. Moreover, what about if I want to apply security on what to show in the menu. For instance, I will have 3 departments ( Finance, Accounting and Marketing ) each department has its own apsx page. Depending on role, I need to show / not show a page under each department. How can I enforce such thing.
View 1 RepliesI'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.

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.
i have a calender control like this
<asp:Calendar ID="CldrDemo" runat="server" BackColor="#FFFFCC" BorderColor="#FFCC66"

</asp:Calendar> [code].....
i want to call the event handler for the dropdownlist - selectedIndexchanged and i have added it also like this
protected void ddlBlist_SelectedIndexChanged(object sender, EventArgs e)
{

but this is not getting fire when i am changing the item of the dropdownlist.
I have an existing dataset in VS2008 and app works fine untill I tried to add new datatable.It gave me the following error -
Custom tool error: Failed to generate code. Unable to convert input xml file content to a DataSet. Invalid XPath selection inside field node.
And designer.cs got deleted.If I mannually add datatable in .xsd then it is good.But that option is not acceptable.
i try to create dynamic control and have a single event handler to ease the fireevent how do i do it?also can i declare a single event handler to parent control and be use by child control of the same type
in example:
creating htmlanchor name aa
aa.Control.Add(any anchor)
