Here I have some rows in a table and am listing out the flags for my products which in this case is called item. When I want to edit the flags as on or off (yes/no), I need to get access to the whole item itself as I have no other way of identifying which item's flag I clicked on.
@foreach (var item in Model)
{
<tr>
<td>
@Html.DisplayFor(modelItem => item.Name)
</td>
<td>
<ul>
@foreach (var flag in item.Flags)
{
<li>
@Html.DisplayFor(modelItem => flag.Name) |
@(flag.Enabled ? "Yes" : "No") |
@Html.ActionLink("Edit", "FlagEdit", new { flagId = flag.Id, itemId = item.Id })
</li>
}
</ul>
</td>
If this isn't clear, please ask and I'll elaborate. I'm trying to send the itemId but because I am within the flags foreach, I cannot get hold of it.
when I get to the first if that checks params are not null, the check fails.
[ActionName("FlagEdit")]
public async Task<ActionResult> EditFlagAsync(string flagId, string itemId)
{
if (flagId == null || itemId == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Item item = await DocDBRepo<Item>.GetItem(itemId);
if (item == null)
{
return HttpNotFound();
}
//do update
return View(item);
}
I've tried searching but maybe I'm just not searching the right keywords. Can anyone please help?
尝试这个:
@Html.ActionLink("Edit", "FlagEdit", new { flagId = flag.Id, itemId = item.Id }, null)
