load external url in page?

I have a treeView that lists SQL Reports available to the user. What I'd like to do is put the treeView into an Update Panel, and some other control that can display an external url, next to the treeView so that when a user clicks on a report, it fetches the contents of the url and displays it without doing a postback. So my question is, are there samples of this out there (I couldn't find any) and if so, what control would allow me to load external content into it (like an iframe)? I realize I could do the same thing with a div or iframe using javascript, but I'd like to use ajax if possible...

Thanks!

Chao,

I would put the iframe inside the UpdatePanel and the Trigger controling the URL's ID from the treeview. This is similar to having a gridview or any view inside an UpdatePanel with a trigger controlling a button. The button is of course outside the UpdatePanel.

p.s. not responsible for not working ... hihihi ... but that's how i see it.

Load external HTML file

Hi All,

I'm very new to this (Ajax & ASP) and am trying to implement something which I think should be stright-forward but am having no luck.

Basically I want to load an external html file (or html snippet) into a section of the current web form/page, I don't want to use iframes for this. I have an idea that I might need to use an UpdatePanel and maybe a DynamicPopulateExtender but can't piece it together.

Any help/direction greatly appreciated . . .

Hi,

How do you plan to use UpdatePanel & DynamicPopulateExtender?

I think IFrame is a good choice for such situation.

Loading external .aspx file into AJAX Toolkit TabPanel

Hello,

I'm new to ASP.NET AJAX. I want to create a default page, maybe a master page. then i want to add the AJAX Toolkit TabContainer with different TabPanels for each of my other .aspx files (home.aspx, about.aspx, etc.) I want to know how I would setup the TabContainer with a tabpanel for each page and load those pages when the appropriate Tab is clicked. a small snippet of example code would be greatly appreciated

Thanks to all in advance

How about something like this?

<ajaxToolkit:TabContainer ID="tabs" runat="server" Width="600px" Height="400px">
<ajaxToolkit:TabPanel ID="tabHome" runat="server" HeaderText="Home">
<ContentTemplate>
<iframe src="http://pics.10026.com/?src=home.aspx" width="100%" height="100%">
</iframe>
</ContentTemplate>
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel ID="tabAbout" runat="server" HeaderText="About">
<ContentTemplate>
<iframe src="http://pics.10026.com/?src=about.aspx" width="100%" height="100%">
</iframe>
</ContentTemplate>
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>

Thanksctafield, that did the trick. works like a charm but I wonder if there might be another way besides frames. I dont like to use frames plus i'm concerned about browsers that may not support frames. Thank you for the quick response

If there is another way I would greatly appreciate the guide

Thanks

Ok, When I used the iframe my pages end up having 2 separate vertical scrollbars. one for the main window and one for the iframe region. i cna see that confusing my users when they need to scroll up or down. has anyone thought of another solution?

you can actually turn off the scrollbars for the iframe - just make sure you set its width and height to 100% so data doesn't get chopped and that would get rid of the scrollbar for the iframe...

iframeid="TargetPane"scrolling="no"

Hi,

You might also be interested in reading one of Scott Guthrie'sblog posts where he created a class called ViewManager to render ASP.NET controls to HTML and send it via a webservice to the page.

Thanks,

You can add WebControls (.ascx) to each panel you want by using following code-behind:

AjaxControlToolkit.TabPanel tpHome = new AjaxControlToolkit.TabPanel();
tpHome.HeaderText = "Home";
tpHome.ContentTemplate = Page.LoadTemplate("Home.ascx");
tcDefault.Tabs.Add(tpHome);

AjaxControlToolkit.TabPanel tpAbout = new AjaxControlToolkit.TabPanel();
tpAbout.HeaderText = "About";
tpAbout.ContentTemplate = Page.LoadTemplate("About.ascx");
tcDefault.Tabs.Add(tpAbout);

tcDefault is TabContainer control.

AjaxControlToolkit.TabPanel tab = new AjaxControlToolkit.TabPanel();
tab.HeaderText = "test_new_tab";
TabContainer1.Tabs.Add(tab);

??index error WHY?

Good piece of code to use the control on the code behind.
Even the control toolkit samples didn't have these in detail

However i couldn't load an external page onto the page.loadtemplate method
It throws the following error when trying with full path

Exception Details:System.Web.HttpException: 'http://localhost:8080/Documents/9245/bjk49000.PDF' is not a valid virtual path.

Any suggestions?

At the moment i'm using the following method by coding on the client end

<ajaxToolkit:TabPanel runat="server" ID="TabPanelAttachment" HeaderText="Attachments">
<ContentTemplate>
<iframe runat="server" id="iframePreview" width="850" height="800" frameborder ="0"> </iframe>
</ContentTemplate>
</ajaxToolkit:TabPanel
var urlPrefix = "http://localhost:8080/Documents/"
var urlSuffix = docId + "/" + fileName;
var url = urlPrefix + urlSuffix;

$find('TabContainerDocument').set_activeTabIndex(1);
document.getElementById('TabContainerDocument_TabPanelAttachment_iframePreview').src = url;

TabContainerDocument_TabPanelAttachment_iframePreview is the iframe id at run time
Hope that helps for someone who is trying on something similar

Happy coding

This reallyhas to be built into the TabPanel tool.

Haven't tried this but it might be another alternative to controls and iFrames...

Dynamic drive website has example of using Javascript to do page calls to a div, not too sure if will work in but might be good for a try?
