Check items in listbox on edit view.

[Bernard Jurlina]

I have checked listbox in my edit view like this:

@Html.EJ().ListBox("lstCountry").Width("100%").Datasource((IEnumerable<SelectListItem>)ViewBag.lstCntry).ListBoxFields(lf => lf.Text("Text").Value("Value")).ClientSideEvents(e => e.CheckChange("onCheck")).ShowCheckbox(true).CheckItemsByIndex(Model.country_filter)

but it won't check items based on country_filter field, which is for example, "AT,AU,AZ".

Thanks!

Well, there is other method checkItemsByIndices, but it works with index values also. That's why my example won't work.

My listbox show values from countries list, lstCountry, for example, "AU" - "Australia"; "AT" - "Austria". How can I check items in listbox on edit view if I save "AU,AT" value in database?

That means that Austria and Australia has to be checked on edit.

Thanks!

Ok, I solved it.

In controllers ActionResult Edit I create a list, List<int> lstidx, and find indexes of save country marks with foreach loop....and forward it in ViewBag.

In edit view I use the ListBox like this:

@Html.EJ().ListBox("lstCountry").Width("100%").Datasource((IEnumerable<SelectListItem>)ViewBag.lstCntry).ListBoxFields(lf => lf.Text("Text").Value("Value")).ClientSideEvents(e => e.CheckChange("onCheck")).ShowCheckbox(true).CheckItemsByIndex(ViewBag.lstidx)

and it works.
