AJAX :: Reorderlist Doesn't Reorder / Can't Drag Items To Reorder?
Jul 6, 2010
I have tried several examples of reorder list with several types of data sources and can't get the list to reorder. I have copied Joe Stagner's code from his Video on Reorder Control with the same result. Here is the Video
http://www.asp.net/ajax/videos/how-do-i-the-ajax-toolkit-reorder-control. Page loads, but I can't drag items to reorder. I have tried this with explorer 8 and firefox 3.6, with and without security. Here is the markup, no code behind.
[Code]....
Some of the events don't seem to fire. DataBinding, DataBound, Load, and InsertCommand work ItemReorder does not, (not good for a reorder control). This control should work, but doesn't. I am able to insert data so it seems that the reorder or dragItem templates maybe causing problems. I have commented out but that doesn't help. Here is my only clue, I had to use the script manager from the .net4 Ajax Control Kit for my events to not complain about definitions. I was only using these events with debugger just to see if they are being called, no code in methods. But I am using the toolkit.dll that came with Joe's example. I tried it with .net4 only first, but that didn't work either that's when I installed the dll from Joe's example.

I have the same problem as Simon in this post. He found out some sort of a solution, but it does not work for me. Please, could someone explain me what is going on in this answer or advice me something else. PS: there is an example on the asp.net site which doesn't work exactly the same way as my reorder list... (click view a demo) The solution that is suggested here adds these few lines to web.config:

Perhaps I just need to change something to make it work... but I don't know what. For example I have no idea what the ScriptResource.axd is supposed to be. My code: .aspx file

I load the data to the List collection from the page_load event but that works fine. The data binding works as well. The problem is in that the items cannot be reordered -- during the reordering, the sort value doesn't change and the list doesn't update.

I'm using a reorderlist (Ajax Control Toolkit Release 4.1.40412.2) inside a scrolling div (class="reorderListDemo" style="overflow:scroll; height:225px; width:1300px; table-layout:fixed; text-align:left;"). When the height of the reorderlist is greater than the height of the div, the div will automatically have a vertical scrollbar. The problem is that when i scroll down to drag an item from the bottom of the reorderlist, the reorderlist does not work properly. The drag image and the drop target does not correspond to the item i want to move.I've attached a copy of my css file:

Here is the html markup of reorder list control:

is it possible for reorder list to to allow user to drag n drop via column cell.
For example,
Column1 | Column2
------------------------------
Value1 |Value5
Value2 |Value6
Value3 |Value7
Value4 |Value8
Value 1 was drag n drop to the position of Value5. And Value5 ,Value6,Value7,Value8 position are reorder like Reorderlist in row.

I am using asp.net ajax reorder list for one single page. It works fine for other computers on our network, except one computer. Regardless what browser she's using, it doesn't work. Is there a setting on the workstation's browser to allow asp.net ajax or something?

Reorder list control cannot be set to not postback? My hope for this control was that I could tie it to a list of data (either a datasource or even a manually created list) and then allow the user to move the items in the list up and down until they liked the new order of all of the elements. They then would click a button to save the updates to the database. Is this possible? It seems that after every reorder there is a postback requried to the datasource to perform an UPDATE, even if the PostBackOnReorder
="false"
value is set.
So if my list is
1 Atlanta
2 Boston
3 Chicago
4 Denver
5 Edmonton
and they want to switch Denver with Boston and then hit the Update List button I could cycle through the list an only update two entries rather than all 5 entries twice (for each Postabk on reorder)

I have an issue with the appearance of my reorder list. The draghandle div is outside of the item template div. I have used the reorder list in the past and the draghandle was always inside of the item template. I can't seem to find any mistakes so is this a bug or do I have a mistake somewhere. All other functionality works great. Here is the code.

I did the tutorial for the ReorderList on the asp.net site: http://www.asp.net/ajax/tutorials/drag-and-drop-via-reorderlist-cs and everything works perfectly. But for some reason when I switch out the references and use the same code for my db table the changes aren't saving. In other words when I use the db table called 'AJAX' that I created based on the tutorial everything works perfectly, but when I use it on my table ('projects') the changes don't save to the db. I can't think of anything in the db that would be causing this to happen.
Here's my code:
//This works
<form id="form1" runat="server">
<asp:ToolkitScriptManager ID="asm" runat="server" />
<div>
<asp:ReorderList ID="rl1" runat="server"
SortOrderField="position"

I am using reorderlist for the first time and I am having trouble getting to display like the default look I see at ajax toolkit examples webpage. Also, when I try to click on it and move any row nothing happens. I have a MSSQL table that has the following 4 fields
ToDoId (primary key, int, identity, not null)
ToDoChar (char(1), null)
ToDoDescription (varchar(50), null)
ToDoPosition (int, null)
I have the following code

I am trying to create a UI that shows a list of pending work on the left side, and a similar list of planned work on the right side. I would like the user to be able to both reorder items within each list - this works fine with reorderlist; But to be able to move an item from one list to the other - this I can't make work with reorderlist. Is this possible and can anyone give some pointers on how to achieve it ?

There are a few posts on the site about how to order by using lambda expressions however I cannot seem to get mine to work. I am trying to reorder a list that is already populated. Am i wrong in thinking that i can rearrange the order of this list using lambada expressions?
QuarterMileTimes.OrderByDescending(c => c.PquartermileTime);
I was wondering if it's down to PquartermileTime being a string? I also tried this expression on a date
QuarterMileTimes.orderBy(c => c.RaceDay);

I'm attempting to use the List Reorder from here: [URL] I've got all the scripts in place, and my events are firing properly on dragging/dropping, but I'm unable to see anything in my object. The goal is to reorder the list, and save the new order back to the DB. I am assuming something is wrong with my syntax in the lists.bind, as it shows the actual items in the list, but the values are empty.
$(document).ready(function () {
var options = {
itemHoverClass: 'itemHover',
dragTargetClass: 'dragTarget',
dropTargetClass: 'dropTarget',
useDefaultDragHandle: true
};
var lists = $('.lists').ListReorder(options);
var items = [];
lists.bind('listorderchanged', function (evt, jqList, listOrder) {
for (var i = 0; i < listOrder.length; i++) {
items[i] = $("ul li:eq(" + i + ")").attr('id');
}
});
$('#btnSave').click(function () {
if (items.length > 0) {
var jsonText = JSON.stringify({ items: items });
$.ajax({
type: "POST",
url: 'ManageSliders.aspx/SaveReOrder',
data: jsonText,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function () { $("#result").html("New order saved successfully"); },
failure: function (msg) { alert(msg); }
});
}
else {
alert("You have made no changes");
}
});
});
I'm binding a listview using C# and that is showing up fine as well.
<ul class="lists">
<asp:ListView ID="lvSliders" runat="server">
<LayoutTemplate>
<asp:Panel ID="itemPlaceHolder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
<li id='<%# DataBinder.Eval(Container.DataItem, "Id")%>'>
<%# DataBinder.Eval(Container.DataItem, "Title")%></li>
</ItemTemplate>
<ItemSeparatorTemplate>
</ItemSeparatorTemplate>
</asp:ListView>
</ul>
I ran it through Fiddler, and it is throwing me this error:
