Web Forms :: TreeView Control Rendering Using Xmlhttp?

Feb 2, 2010

I am developing website using xmlhttp request.I am using treeview control in a webpage.I am sending xmlhttp request to page for adding a treenode to treeview control.I added a node in the treeview control and i render the treeview control html using control.render method and send html to client through without postback.But i am not able to maintain the state of treeview control like selected node and expanded nodes.So I want to send state info to server through xmlhttp and how to update the state info in server,aslo i need to update the treeview control javascript objects like treeview_data which maintains the treeview state when i return back from server.

Web Forms :: TreeView Control Not Rendering Styles Correctly In Chrome, Firefox, Safari, But Fine In IE

Feb 15, 2010

I've defined node styles for my TreeView instance in markup (using <LevelStyles> for example). Everything renders correctly in IE7/8 but, when rendering in Chrome, Safari or FireFox, the styles are not being applied. From looking at the source code for the page, I can see that the various runtime css classes are being injected into the top of the page, but the class attributes on the <a> tags (within the generated TreeView HTML) are empty (class=""). In IE, the class attributes contain references to the classes that were injected into the page.

Can anyone explain why this is happening? I can see no logical explanation for this, and it's a big issue - My client primarily uses Safari, as they're Mac based.

Web Forms :: XmlHttp To Make Link Visible?

Jul 29, 2010

I've successfully used the xmlhttp object to redirect (xmlHttp.open) user to another page but I have the following issue ..I have a classic ASP application that has some very antiquated "admininstration" functionality built in that loops through a SQL table with NT Accounts and allows the link to only be visible to users with NT account in the table. We have since moved on to manage permission to our .net apps using an object that looks for your NT account in an Active Directory Group. So, I would like to use the .net object to return True if NT account is a member of the group and then display the link (which is in the classic ASP page) if the .net object returned true.I don't know if that can be done .. I just know I'm able to return the TRUE value using the xmlHTTP ajax object but I only want to set visibility of a link rather than xmlHttp.open to redirect to another page.

Web Forms :: Menu Control Not Rendering In Chrome & IE8?

Jul 28, 2010

I am testing my website in numerous browers and have discovered (amazingly) that the asp:menu

a large part of internet traffic it is curious that microsoft have not fixed this. I have looked at CSS Friendly but

if looks like a lot of work and change for my websites just for the one control that does not work.

Web Forms :: Menu Control Not Rendering Hover Styles Correctly

Aug 22, 2010

I've encountered was appears to be a strange bug with the menu control, and alas, I am unable to find much useful information on it (which leads me to believe I have something installed or confingured incorrectly). Here the problem:

When declaring a menu control with a staticHoverStyle, for example:

<asp:Menu
ID="navMenu"
DataSourceID="srcSiteMap" [code]....

Has no effect on the behavior of the control once it's rendered, neither in Firefox nor IE.In fact, using the source code at

http://msdn.microsoft.com/en-us/library/ms366731.aspx with no modifications also results in the hoverstyle not working.

This problem seems to be "fixed" if you specify the css attribute declaratively, for example, StaticMenuItemStyle-BackColor="Yellow".
Alternatively, if you specify RenderingMode="table" then the hoverstyle seems to work. It's only when you're using a cssclass with a list that things seem to mess up.

Finally, I notice that in the rendered html, the control embeds some styles between /* <![CDATA[ */ and /* ]]> */ comments that affects the final appearance of the menu control, sometimes overwriting a cssclass you specified (ex: the margin for dynamic menus can only be controlled with the HorizontalOffset property, and not by css). This is undesirable, but I don't see anything that seems to overwrite the behavior of hover elements. Actually, the .hoveritem class doesn't appear anywhere in the markup at all, but when you specify the StaticMenuItemStyle-BackColor property, then the value is rendered correctly in this block of styles.

AJAX :: User Controls And Control Extenders / Rendering A SPAN As An Element To Surround The Control?

Aug 24, 2010

Two separate questions, but sufficiently intertwined that I'm going to try the two together....

Firstly - User Controls and Behaviours

I have a User Control which contains a few visual controls. I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences. That is all rock solid and working well. However, when developing, I did discover that I couldn't attach the ehaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control. So, I have attached my behaviours to a "random" TextBox within the User Control.

So - first question, is there a better way to do that? For example, should I always be rendering a SPAN as an element to surround the control? Not sure what that would do to the robustness of the rendering. What is the right way to attach a behaviour to a User Control.

Secondly - Accessing those same Behaviours later

Assume I have placed a User Control on the page. That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour). I then have a behaviour on the same page (actually an Extender on a different control) which needs to call the function. I have a reference to the User Control in my script, so I have tried TheControlReference.set_Border('red') and find that my control doesn't support the set_Border method.

I guess this is probably because the behaviours are not attached to the User Control itself, but to a GUI element within it. Hence, I suspect that the answer to the second question lies within the answer to the first.

AJAX :: Error When Rendering A Rating Control In A Composite Control?

Feb 11, 2010

I have a custom control that renders different controls based on a property value. This all works correctly until i try and add a rating control to the control. When i render both controls in the CreateChildControls the control is rendered properly.

However when i try to add layout by overriding the RenderContents method and rendering controls there, an error is generated
Extender controls may not be registered after PreRender.The code shows both methods of creating the controls.

Web Forms :: Image Control / ImageUrl From A Network Folder Not Rendering In Firefox?

Nov 11, 2010

I have an Image control with the ImageUrl property set to point to an image on a network folder, the address looks like this:

\fs01PRODUCTSimagesAM101.jpg
It renders correctly in IE but not in Firefox.

pasting the url/path directly into the browser, the address is maintained in IE: \fs01PRODUCTSimagesAM101.jpg

But in Firefox, it is converted to this: file://///fs01/PRODUCTS/images/AM101.jpg

I suspect this is related to the problem.

Web Forms :: Display Menu Control Items Like Table Without Setting Rendering Mode?

Mar 2, 2011

I hate tables - don't want to use tables, unless I have tabular data to display. A menu is not tabular data (as far as I am concerned.) I was elated to see that in asp.net 4 - the menu control renders as a <ul> <li>, instead of as a table. However - try as I might, I can not get a horizontally orientated Menu to split into even columns, and text align center. FYI - I don't use fixed width - so I can't just set a width to 1000 - and separate it into even columns. Besides that, I want it to change width dynamically, based on the number of "columns (menuItems)" there are. Is it possible to spread out the <li> menu items evenly across the space I provide for them in their containing div or will I have to quite using menu controls, and start using JQuery Menu's?
