i have a very large amount of data which i need to view in form of a tree. The problem is, that this runs sometimes into a timeout exception or it takes very very much long! I saw in several Application that others build up a tree where the node expand and load the data partially. So i would like to build something like this for my application, too, but i dont know how to contruct this.
- MyTreeNode1
+ MyTreeNode 2
- My TreeNode 3
wait while Data is loading ... (or the treenode is getting built up and i see it live, instead of showing an progress indicator)
+ My TreeNode 4
i dont know how to do this but would like to learn :) Could someone give me the right keywords to look for, or guide me?
I am building treeview using asp.net 2.0/3.5 from master detail table.
ParentTable Value ---ChildTable Value ---GrandChildTable1 Node ---GrandChildTable1 Value ---GrandChildTable2 Node ---GrandChildTable1 Value
I have created something like this to populate node values. But I am not sure how to display GrandChildNode and values. Could you please let me know if there are any ideas?
protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e) { switch (e.Node.Depth) { case 0: GetParentTableValues(e.Node); break; case 1: GetChildTableValues(e.Node); break; case 2: } }
i have this situation: i have to build a menu with datasource from the db, because i have to filter them among the user that is loged in. i have tried building a menu using repeater, and all this works fine till i realized that i wanted the menu with more than two levels. i have also tried with treeview, but i really don't want this solution (problem with the style and the treeview doesn't have a pretty view).
I have a question regarding a situation that occurs with GridView, ObjectDataSource in ASP .NET application. The GridView is linked to the ObjectDataSource and both are included within an UpdatePanel letting the GridView to fill in an asynchronous way from a form in the same page so it gets more rows as the user enters the data:
I start the project with Visual Studio 2008, fill the form and it works correctly. Then I stop the execution: rerun again and the data I entered in the previous run is in the GridView. Is like some sort of cache saved the data from the session before. I checked that EnableCaching property is set to false for the ObjectDataSource. If I Rebuild Web Site in Visual Studio (not just Build) then it works corretly leaving the GridView empty. Is this caused just becuase of Visual Studio? Can it be turned off? And will it happen in the final IIS it will run on?
I want to build a survey system where you can build a form with questions and some answers to these questions and then members who will log in will be able to take the test.
Then i want to present the different results from the test in some diagram or something like that.
I have a TFS build set up to deploy an ASP.net project to a test server.The build works great, and deploys to the test server fine, but instead of putting it into the Website directory that my IIS webserver is configured for, it puts the build into Website_20100511.6
Why is the date suffixed to the directory name? Is there a way to turn that off so I can publish directly to the Website?
What is the quickest way once I have JSON array in hard to actually manufacture HTML? I'm thinking it's iterating the JSON arrays pulling out needed data and concatinating an HTML string that I pass to eval()? Is there a faster way?
I've had the lastest build in use for a while but only tried using a CollapsiblePanel yesterday and found it didn't work. No clues as to why not. The panels just stay open and images show as empty.
Just moved to ASP.Net 4.0 with VS2010. Is this the issue?
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.

Looking at the source code it seems to me that all the paths have been changed, but i cannot understand the right namespace to use with the latest release.

have embedded a TreeView inside an Update Panel, PopulateOnDemand in use.When a top level node is expanded everything is fine - the level 1 (zero base) nodes are populated.When on of these lower level nodes is expanded the tree Collapse
how to update treeview using updatepanel?I am binded my treeview using xml datasource,periodically the datasource was updated,so i am used updatepanel in treeview but, it is not updating while changes came.when i refresh that page ,it is update
I have read several post on the TreeView is not/partly working with the UpdatePanel, but none of them mention that an update (triggered by a timer) causes creation of multiple javascript functions in the HTML header. In Mozilla Firefox this a memory leak. I have created a test webapplication to demonstrate the issue we encounter.
I have some Issues 1)Can we use asp.net Tree view with Update Panel??I am using its event like populate and checkchanged etc If yes then please give Reference if available or whatever possible 2)When User Click on checkbox of treeview by the help of javascript "__dopostback" i am able to use checkchange event when user click on check box of treeview how can we handle all this by update panel to get rid of post back or others teachnique ??

I have a VS2010 Web Application that uses the AjaxControlToolkit. I am able to build the Debug configuration. When I build the release configuration I get the following error message: Error 89 Could not load file or assembly 'file:///S:My CodeLibrariesACTMay 2010AjaxControlToolkit.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) S:My CodeEZFishingEZFishingEZFishingSGEN EZFishing
The location of the file is correct, and I just downloaded and unzipped there the Ajax CT. I have always built this app correctly before upgrading to VS2010 and ACT May 2010.
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.
