TreeView controls are a little Hairy when using them for display of things like Hierarchical data.In my case, I am using it for the display of Roots and Leaf Nodes (Child Nodes) and everything in between to get chains of selected nodes back to the Root Node (final Parent Node) in a detail list that is another database call for the Detail Sheet on the"Checked" boxes of chained branches in the TreeView.
View 2 RepliesI am trying to refresh an asp.net page using this command:
<meta http-equiv="Refresh" content="10"/>
On that page I have 2 treeviews. The refresh works ok when I just open the page, but when I click on one of the treeviews and expand it, the refresh stopps working and the page isnt being refreshed. Is there any connection to the treeview being expanded? Here is the full code of the page:

I've implemented the JQuery Async Treeview (in APS.NET MVC2) and it works fine, but the problem is when the user adds new nodes to a tree (via another interface), there is no way to reload the tree and reflect the new tree structure.
The only way to see the changes in the tree is to shut down the browser (IE8). Trying .empty() on the tree on every reload doesnt do anything.
Heres the page source:
[Code]....
the URL /OrganizationStructure/Browse is only called when the tree is being built the first time..i cant for the life of me get it to rebuild even when the browsers "Refresh/Reload" button is clicked.
I have an app that uses masterpages. On the masterPages I have a TreeView. I would like to only refresh the ContentPlaceHolder & not the Entire masterPage when a link is clicked on the treeView.
I have placed the contentplaceholder in an Updatepanel. I would like to if possible avoid including the menu in the update panel.

I have a layout problem where I canīt get things centered in a Table.What I first have created is a Table. Inside this table I have created a panel wich I like to be centered in this table so I have set it like this but still the panel is to the left in the table ? This is the first problem.
<td align="center">
Then I have TextBox77 that I like to be centered in this Panel9 wich it is, setting HorizontalAlign="Center"
So I would like this Panel9 to be centered in the Table but still the Panel is to the left in the Table ?

I'm curious, anyone know the mechanism a checkbox control uses to remember that its checked or not checked after a postback?If I add them manually to a page via html as in <input type="checkbox"/> I have to use javascript and hiddenfields to keep things checked after a postback and I would have to have an onclick="dosomething()" inside the tags.Viewing the html source code for a page with a .NET checkbox control, there is nothing like that there.
I was writing a custom control and rendered my own checkboxes when I came across this problem. After the postback, the control would reload the checkboxes from viewstate and forget the user had clicked anything. As I couldn't use hiddenfields to track the changes (they got reset from viewstate too), I ended up using .NET checkboxes as childcontrols instead but this experience got me thinking.
I am trying to get a unoranized (ul) list to center. It seems like I use text-align: center;, but for some reason it is not working. Is there some sort of horzontal align as there is vertical align.
If so, I have never seen it.
My css code is as follows:

I am using a master page with some graphics but things just will not line up really well. I cannot work out what is going wrong.
I have white deadspace at the bottom of my left pane. Deadspace to the right of my top header pane. It looks really bad.
To save time I have my test project zipped. It works on VS2010. Its very small, I could email it to someone if they would care to look. Or if someone can tell me how to attach zip files to these forum posts i can do that.
If not I will have to insert the 4 images used and post the relevant code.
is it possible to allow user to type things into the dropdown box?
View 2 RepliesPeriodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

I can add a row to the bottom of a listivew by inserting a table after the layouttemplate in a listview. It works fine for me to call the added controls from code-behind and chane the control values. Since my listview changes width dynamically depending on the contents of the data, my added table columns don't match up.
I have tried to access the width property of the table and then match the new ones with codebhind, but it doesn't seem to work.
I am simply trying to add a row to the bottom of the listview to provide for totals of the columnts. What is the best way to to that?
I have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.

View 1 RepliesI have a problem when I try to pass in paramaters for a report in my report viewer. I have set up the ObjectDataSource and set the paramaters for 3 text boxes that are on the page. The only way I have found to set the paramaters for the report is the user must fill in the paramaters and hit the refresh button on the Report Viewer toolbar ,but I would like to have the user click a asp.net button insted. Is there anyway to call the refresh method from codebehind?

Might remember me being so enthusiastic about asp.net mvc a while back.Got a bit caught up in other things (more php, and dip in the Java pool), and completely stopped following the asp.net world a few months.Just curious how things evolved? Did MVC catch on (as I for one believed it would) or.... what?Cannot really post the reason for me asking this, but guess a safe way for me asking is: 2 guys with kick butt skills...one asp.net webforms masta, the other asp.net mvc .... who's the best off?

I'll try to be short and get right to defining the problem. We have an ASP.NET 2 application (eCommerce package) running on IIS (Windows Server 2003). The main site's page(s) are using plain HTTP (no SSL), but the whole checkout process and the shopping cart page is using SSL (HTTPS). Now, the problem is that the site's header is located in a template file, and inside it it has a plain HTML 'img' tag calling an image with the "http://" portion hard-coded into it... This header appears on absolutely every page (including the https pages), and due to its insecure image tag, a warning box pops up in IE on every stage of the checkout process...
Now, the problem: The live application cannot be touched in any way (no changes can be made to the template (so simply changing "http://" to "//" is not an option), IIS cannot be restarted, and the website/app pool cannot be restarted). Is there any way in the world (maybe plugin for IIS or a setting somewhere) that I can filter the pages right before they are served to replace the '<img src="http://example.com/image.jpg">' with '<img src="//example.com/image.jpg">' in the final HTML? Possibly via a regular expression or something?

View 3 RepliesMy issue is similar to ASP.NET Debugging Timing out with IIS except that I'm using the built-in ASP.Net Development Server with VS 2010.If I pause for more than about 10 seconds in the debugger, IE7 "disconnects" from the web server with the error message Internet Explorer cannot display the webpageHowever, unlike in the similar question, the debugger is still running. If I refresh the browser it will post that refresh to the server and I can debug the page from the top again.
Is it possible to configure things so that IE7 waits (much) longer before giving up?If it makes a difference, I'm launching IE using the "Start external program" option and passing a localhost URL as the command line argument (since Chrome is my default browser). I also specify a specific port.
I'm trying to use images representing arrows to allow the user to change the order in which items appear in a list in a grid view in ASP.NET.
