View 1 RepliesI 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:
<form id="form1" runat="server">
<div>
<asp:WebPartManager ID="WebPartManager1" runat="server">
</asp:WebPartManager>
<asp:WebPartZone ID="LEFT" runat="server">
<ZoneTemplate>
<asp:TextBox ID="tb" runat="server" />
</ZoneTemplate>
</asp:WebPartZone>
aa
<asp:WebPartZone ID="RIGHT" runat="server">
</asp:WebPartZone>
aa
<asp:EditorZone ID="EditorZone1" runat="server">
</asp:EditorZone>
</div>
</form>
Here is the code behind:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
WebPartManager mgr = WebPartManager.GetCurrentWebPartManager(this);
mgr.DisplayMode = WebPartManager.DesignDisplayMode;
}
What am I missing?

View 4 RepliesFor our next project (a small app in ASP.NET/C#) we have to create drag and drop zones in the UI so that components/widgets can be dragged and dropped and layouts can be changed dynamically (for example, the user should be able to switch between two-column to a three-column layout from the front end). After doing some searching, I got to know that there are two approaches: Use Web parts and Content-zones. Using jQuery.
I also learnt that jQuery approach is preffered, but I would like to know how can I create such zones in my application and also save these zones per user (in the D so that when the new request comes for that user their preferred layout is displayed? I basically want to know if there are some tutorials on creating persistable drag and drop zones using jQuery.

View 1 RepliesI have been using web parts on my site since ASP.NET 2.0 came out. Dragging and dropping web parts works great in Internet Explorer, but it doesn't work at all in Firefox, Chrome, or Safari. I recently upgraded the site to ASP.NET 3.5 SP1, but I am still unable to drag and drop web parts in non-IE browsers. How can I enable drag and drop web parts in these other browsers? Update (2/9/2010): This mentions this problem, but offers no solution: [URL] pdate (2/19/2010):
These posts offer a possible solution, but I have been unable to get it working yet on my site: [URL] In short, these say the drag and drop problem was solved in "ASP.NET Futures (July 2007 release)" but for some crazy reason, was left out of ASP.NET 3.5 SP1. So to solve, you have to download the Futures release at:
http [URL] Then, you need to use the WebPartManager and WebPartZone from the Microsoft.Web.Preview.UI.Controls.WebParts namespace.
