Web Forms :: Treeview With Drag And Drop From Listbox?
Oct 27, 2010
Users want to have the ability on a page to have a treeview with hierarchy that can be updated by dragging and dropping from a listbox. They can drag a change request from the listbox and drop it on the treeview as a parent request or a child of one of the treenodes. There also needs to be the abililty to drag and drop from within the treeview. With all the changes being done, the item from the listbox would also need to have a field changed to either Parent = 'Yes' or IsChildOf = parent id. My first question is;
1) Is all of this possible?
2) Know of any samples or examples of how this would be accomplished?
3) Is there a better way of doing the hierarchy with parent and children then mentioned above (I hope there is)?
4) What have others done for something like this?
I am open to other thoughts of doing this a better way and I'm sure the users can be persuaded. Prepping for a Access conversion project beginning of year. And if this conversion from A2007 to ASP.NET goes well, there is another major conversion waiting in the wings.
I want to know how to handle drap and drop event between two listboxes. I have two listboxes. If I drag one item from one listbox, it will drop on other listbox. And also let me know how to rearrange the items in listbox.

Could you point me to a reference article on how to implement drag and drop within a treeview control using ASP.NET in C#? Is this best implemented with AJAX? I will be using an XMLDatasource. Also, I did not want to use any third party control at this point

I currently have two listboxes and I use arrow buttons to move items from one list to another. Is there a way I could implement drag and dropping between those 2 listboxes.
I cannot get the Drag and Drop functionality of Web Parts is to work. I have a very simple test page with two WebPartZones.. In the OnInit method of the code behind I put the page in design mode. In the first zone I have a textbox.At runtime the text box renders as a web part. When I hover over the web part header my mouse pointer changes the 'move' pointer, but I cannot drag the item. I do not see it dragging and the part never moved. I am using Visual Studio 2010 with IE 8. I have tried IE8 in compatibility mode and regular mode. The results are the same. Here is the markup from my test page:
I came across this example [URL] I want to create a form that will be validated when Submitted. In the above example you can keep on dragging colored boxed on the Drop It Here area. When a form is submitted, I want to validate Drop It Here area to see if it is empty or user drop a colored box here. Is this possible to do and if so, how to do it. I tried regular validation coltrols and they didn't seem to work.

I use VS 2008TS SP1 on .NET 3.5SP1... when i treid to drag and drop controls to the form, it wouldnt add any here a small video on youube.com explaining my situation:
I'm trying to develop a web application where there webpage would contain a list of Web control (textbox, label, calendar...) images on the left (as a menu), and the user would be able to drag any of the images onto a specific space within the page and it would dynamically create that specific control (for example, if the user drags an image of a TextBox into a panel, then a TexBox control would be dynamically created into that panel). Basically, I need to reproduce the basic drag-and-drop functionality of an IDE. To be honest, I have no idea how to do this.. anyone can point me in the right direction??
Can the ImageButton Control be used to implement Drag&Drop? My Drag&Drop function means drag the image,and drop it to desktop as a file or other applications, for example, Office Word,Office Excel,etc. Can the ImageButton Control be used to implement it?
Is there a way to change the code inserted when you drag and drop a control on a form?For instance, the application I'm working on always has Display=Dynamic and CssClass="errormessage" in a field validator. Is there a way to get VS 2008 to use these defaults, and insert the code for them when I drag and drop a control onto the page?
