Treeview / Listview Combination Or Alternative?
Feb 18, 2010
I need to create an ASP.net page that has a control on the page that has a five-level TreeView on the left side of the page, and accounting balances on the right side the coincide with each breakdown in the tree. Top level is company, next is group, next is program, etc... and the balances break down accordingly.
I've seen that there are controls out there such as TreeView/ListView combination controls that can do this. Is there any tutorials or out there on how to go about accomplishing this without paying for controls? Could a treeview do this alone by spanning data across the entire length of the columns since every level will have totals on it?

Currently im using EF and using its datacontext directly in all of my actions, but since i started reading about loose coupling and testability im thinking that thats not the best way to go. Im trying to understand all the pro's and con's before i start refactor all my current code.
Problem 1:
Considering that every entity needs its own repository, and thus has to setup its own connection to a datasource (lets assume a database using EF), wouldnt that give alot of overhead if i need data from 5 different entities on a single page?
Problem 2:
What im seeing aswell in all the examples which i found online is that most people (even people like shanselman) implement the repository pattern using the entity classes which are generated by either LINQ or EF, doesn't this defeat the purpose of repository pattern with regards to loose coupling? On the other hand, what is the alternative, using POCO classes in combination with for example AutoMapper? (this scares me a little) Im hoping that a few people can shed some light on this, because im a bit confused at the moment if the repository pattern is the right choice for a website.

I am trying to rewrite an Access Database in to a asp.net front end and i have hit an issue that i can not find a good way round.
in the access version of the software there is a screen the displays all cusotmers and invoice information about these customers, there are currently 15 columns on the screen and we currently have around 25K customers and this will only go up. This is done using a multi column listbox i need to replicate this screen in asp.net but i spent all day on this on as yet not found a good way of do this.
the user will need the ability to select multiple customers at a time and because of the amount of data a scroll bar is a must, this is why the listbox is an ideal tool, apart from the fact the standard one in asp.net does not allow multi columns. grid lines would also be useful. I have look at a few third party multi column multi column list boxes but the only one that i have found that seems to work OBOUT's takes far to long to render 25K rows.

I stumbled into a problem which is that FindControl will only return a control in the ListView after the listview has been databound. Here is the code which is not working, and I'm getting the "Object reference not set to an instance of an object error" when I try to add the attribute to the control:
[Code]....
Any ideas on how I can elegantly fix this?

I have a ListView control that might be empty sometimes. I would like to show a text message like: "No items to Show" when the ListView is empty.
I have read the FAQ of this forum. This issue is not there.

Within SharePoint...
I can create web parts which are ASP.NET web apps, which allows me to get information about the current user (groups they are in, username, etc.).
I can create web parts which allow me to manipulate fields on SharePoint forms.
But I have not found a way to be able to combine the two things.
I can't access the content of one web part from the other kind (WebApp Page Viewer & Jquery Content Editor Web Part being the two kinds).
What I would like to be able to do is create a web service and then consume it with a jquery ajax call, but I keep getting a js "Access Denied" message.

I have very strange Cascading Dropdownlist behavior. When I use one parent, one child - everything is fine, but one parent two children combination does not work well. Sometimes both children show right data; sometime first is fine and second is grey, or first is fine and second [Method error 500], or second is fine and first is wrong and so on.
Did somebody try to use parent two children combination?

What i would like to accomplish is that a partiel view contains a form. This form is posted using JQuery $.post. After a successfull post javascript picks up the result and uses JQuery's html() method to fill a container with the result.
However now I don't want to return the Partial View, but a JSON object containing that partial view and some other object (Success -> bool in this case).
I tried it with the following code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit(int id, Item item)
{
if (ModelState.IsValid)
{
try
{
[Code].....
However I don't get the HTML in this JSON object and can't use html() to show the result. I tried using this method to render the partial as Html and send that. However this fails on the RenderControl(tw) method with a: The method or operation is not implemented.

Periodically 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 have two solutions, 1st one is webapplication, 2nd one is website.
the 1st soltions (webapplication) includes aspx pages, user controls .... etc.
the 2nd solution (website) also includes pages, user controls ... etc.
now i need to combine between those, so i copy the webapplication inside a folder in the website, and i put the DLL's for the webapplication inside the main Bin folder, and the theme's like so.
but after that, i make some changes in the source code of webapplication, i build the solution, but the new source code updates doesnot appear in the run time !!!! its still running the code before i make combination !!
does that because i make the 1st solution as a webapplication ?
how can i convert the 1st solution to a webapplicatoin? or in other words how can i make combination between webapplication and website to run as one solution?

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.
