Getting item index in BindTo method

[Ian]

I wanted to set the menu item selection based on a persisted item index but cannot see how I can access the menu item index from within the BindTo() section. I have worked around this in the code below by matching on the label but this is not ideal. Is it possible to compare the item index instead?  Thanks.

@(Html.Kendo().Menu()
      .Name("viewTypeMenu")
      .HighlightPath(false)
      .BindTo(Model.ViewTypeLabels, (item, value) =>
      {
          item.Text = value;
          item.Selected = (value == Model.SelectedViewTypeLabel);
      })
)

It depends on the type of "ViewTypeLabels".
If its simply a List<string> you can use IndexOf.

Example:

@(Html.Kendo().Menu()
      .Name("viewTypeMenu")
      .BindTo(Model.ViewTypeLabels, (kendoMenuItem, labelValue ) => {
          kendoMenuItem.Text = labelValue;
          kendoMenuItem.Selected = (Model.ViewTypeLabels.IndexOf(labelValue) == Model.PersistedIndex);
      })
)

Hi,

You could also use a separated parameter to track the index:

@{
    var index = 0;
}

@(Html.Kendo().Menu()
      .Name("viewTypeMenu")
      .HighlightPath(false)
      .BindTo(Model.ViewTypeLabels, (item, value) =>
      {
          item.Text = value;
          item.Selected = index++ == selectedIndex;
      })
)
