Adding Trigger To UpdatePanel from Content Page

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :ASP.Net
Hi guys,    I got an updatepanel which contains a normal panel on MasterPage. The updatepanel does not contain content place holder. On the content page, I have to add triggers to updatepanel for buttons that are dynamically created on "page_load" event. The problem is that, since the page_load event of content page is being called before master page's page_load event, UpdatePanel is not being created. So that, whenever i try to add triggers in page_load event of content page, i got an error like "A control with ID 'ctl00$editableContent$ctl42' could not be found for the trigger in UpdatePanel 'up1'." How can I resolve this problem? The code below is for adding triggers to updatepanel for buttons.MasterClass master = (MasterClass)Page.Master;            AsyncPostBackTrigger trig = new AsyncPostBackTrigger();            trig.ControlID = button.UniqueID; // i have tried button.ID but that does not work as well :)                        trig.EventName = "Click";            master.UpPanel.Triggers.Add(trig);Regards,Kemal

Dynamically adding content to page outside of the aspnet form from within a UC


I have a uc which generates a html form  that should auto-submit when the browser loads the page, so I need to add the form to the page before the </body> tag - outside the asp.net form, id like my UC to work without having any requirements on its parent page / masterpage.

i have managed to add a literal inside the body tag by calling the following inside CreateChildControls on the parent page
Me.Form.Parent.Controls.AddAt(0, ltl)
however this required the body to have runat="server" and the code to be added to the user control's parent page. ( this also seems to cause the viewstate to be lost after postback)

Is there any way i can append the string to the rendered html inside the body but outside the <form></form> from within the UC code

Incase it makes a difference the UC is being added dynamically to the page.

Adding the Content Editor Web Part to a SharePoint Layout .aspx page



we've created a layout page that contains the Rich Text Editor web part. But the client requires a web part that allows the embedding of audio/video files. The Rich Text Editor strips out the objects when we try to embed them.

I've used the Content Editor Web Part to add audio and video files (by manually adding the web part to the page), but I can't find the definition for that web part to include it in the layout page so that the client doesn't need to manually add the web part themselves to every page that requires it. (Which could be many pages.)

Any help would be appreciated.



Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?


Passing Linq Statement between master and content page


I usually work with windows forms, and am just starting to work with ASP.Net, so appologies if this is a dumb question!

I have a master page which has a search button on it. The results of this are built up using a Linq statement and if there are any results, I want to display the results in a contents page.

On the masterpage, I have the following code:

Private _res

    Public Overridable ReadOnly Property SearchRes()
            Return _res
        End Get
    End Property

 Private Sub DoSearch()
   'some code to get a linq result

    If res.Any Then
            _res = res
            Server.Transfer("SearchResults.aspx", True)
            'no results
            LabelNoRes.Visible = True
        End If
 End Sub

On the SearchResults.aspx page I have this code.

Dim m As pxSite = CType(Page.Master, MasterPage)
        If m.SearchRes IsNot Nothing Then
            Label1.Text = "Results found = " & m.SearchRes.Count
        End If

m.searchRes is always nothing. 

What am I doing wrong here?

Adding table to a page, but the format lost when I use clear border



I added a table to a page, by default, the table layout is the light border. So, I add my content and the vertical align seems to set to the top. But when I changed it to clear border, the content of the table will set vertical align to center. Is there a way to change this back to top align but with the clear border. I don't think I can do this by what is available in the ribbon. Please advice.

Adding a custom ASP page to a sharepoint 3.0 site


I have a custom ASP page that I need to add to my sharepoint 3.0 web site.  I created a virtual directory under my website and placed the ASP file.  When I link to the ASP file, I get a 404 page not found.  To make sure I had the correct URL path, I created a test html file and placed in the same virtual directory and linked to it just fine.  I think it has something to do with managed paths and sharepoint trying to control this new ASP content.  I cannot figure out how to exclude this content from managed paths.

Any suggestions on how to resolve this issue so I can run this custom ASP file under sharepoint 3.0?
