I've had no problems working with this control using DataSources declared in the .ASPX page. However, I am having a fun time trying to get this working with DataBinding from our DataBase.
Where I have gotten so far:
List Renders
List Will Re-Order perfectly
List Will Post Back only to the Page_Load event... no other event
I have the event: rlValues_ItemReorder declared and it should be going to that event, but it doesn't.
During postbacks to the server, I check to see how many items the Re-Order list has in it, and it tells me 0. I had the original DataBinding in an if(!IsPostBack) on the page load, and I've changed it so it binds on each page load. I'm not sure which one I need.
Here is the code I am working with:
Item.Fields.FieldList objFieldList;
int intFieldID = 1;
protectedvoid Page_Load(object sender,EventArgs e)
{
objFieldList =newItemManagement.Item.Fields.FieldList(base.GeneralSettings.ConnectionString, intFieldID);
BindData();
}
privatevoid BindData()
{
rlValues.DataSource = objFieldList.ListValues();
rlValues.DataBind();
}
protectedvoid rlValues_ItemReorder(object sender, AtlasControlToolkit.ReorderListItemReorderEventArgs e)
{
thrownewException("The method or operation is not implemented.");
}
protectedvoid btnInsert_Click(object sender,EventArgs e)
{
if (txtValue.Text !="" && txtText.Text !="")
{
objFieldList =new ItemManagement.Item.Fields.FieldList(base.GeneralSettings.ConnectionString, intFieldID);
objFieldList.InsertValue(txtText.Text,Int32.Parse(txtValue.Text));
BindData();
}
}
Here is the .aspx side I'm working with:
<atlas:scriptmanagerid="ScriptManager1"EnablePartialRendering="true"runat="server">
<ErrorTemplate>
<divstyle="padding: 12px; width: 400px; height: 140px; border: #000000 1px solid;

Any help would be awesome.
Thanks.
I believe you need to rebind each time. Without rebinding the list thinks it has zero members, and (using the latest drop from CodePlex) throws exceptions in (as I recall) reorderList.cs ('Item index > count' or something like that). Further code there invokes the Reorder function, so if it bombs out your reorder function never gets called.
The main issue I see with my example is that It never hits the re-order event (if that is what you mean).
The Version I'm using is the newest one from CodePlex... but I have yet to see any errors from the control.
Shawn helped me with this. If I take the Order field out (seeing i'm binding with an IList) it works perect.
