[Solved] Pressing Cancel Edit Duplicates Columns

[Zero]

Yeah. I can't quite explain why this happens. It's related to my drop down problem (I think) since when I press cancel I get a second helping of columns in the same row (it looks like the item template next to the edit template, complete with buttons and clipping issues), which include the drop down boxes, yet they don't show up when pressing the original edit button. It's rather strange. Here's some code:

@(Html.Telerik().Grid(Model.Milestones)
    .Name("MilestonesGrid")
    .DataKeys(x => { x.Add(p => p.Id); })
    .ToolBar(commands => commands
    .Insert().ButtonType(GridButtonType.ImageAndText).ImageHtmlAttributes(new { style = "margin-left:0" }))
    .DataBinding(binder =>
    {
        binder.Ajax()
            .Select("Details", "Milestones")
            .Insert("Create", "Milestones")
            .Delete("Delete", "Milestones")
            .Update("Edit", "Milestones");
        /*.Select("SelectAJAXMilestones", "Grid") .Insert("InsertAJAXMilestone", "Grid");
        .Delete("DeleteAJAXMilestone", "Grid") .Update("UpdateAJAXMilestone", "Grid");*
        /*Some more info needs to go here*/
    })
    .EnableCustomBinding(true)
    .Columns(columns =>
    {
        columns.Bound(x => x.Project_Id).Hidden();
        columns.Bound(x => x.Number);
        columns.Bound(x => x.Name);
        columns.Bound(x => x.Status_Id).Template(x => DropDowns.MilestoneStatus.Single(y => y.ID == x.Status_Id).Name)
            .ClientTemplate(Html.Telerik().DropDownList().Name("MilestoneStatusDDB<#= Status_Id #>").BindTo(new SelectList(DropDowns.MilestoneStatus, "ID", "Name")).ToHtmlString());
        columns.Bound(x => x.PlannedDate).Format("{0:MM/dd/yyyy}");
        columns.Bound(x => x.LatestEstimate).Format("{0:MM/dd/yyyy}");
        columns.Bound(x => x.MilestoneType_ID).Template(x => DropDowns.MilestoneType.Single(y => y.ID == x.MilestoneType_ID).Name)
            .ClientTemplate(Html.Telerik().DropDownList().Name("MilestoneTypeDDB<#= MilestoneType_ID #>").BindTo(
        new SelectList(DropDowns.MilestoneType, "ID", "Name")).ToHtmlString());
        columns.Command(commands =>
        {
            commands.Edit().ButtonType(GridButtonType.Text);
            commands.Delete().ButtonType(GridButtonType.Text);
        }).Title("Commands");
    }).Editable(edit =>
    {
        edit.Mode(GridEditMode.InLine);
        /*Some more info needs to go here*/
    })
    .Scrollable())
