Chapter 16 - Try it Out Checking Roles with IsUserInRole at Runtime

skachy · December 31st, 2010, 10:22 AM

Hi,
I have completed this excersie, but i cannot see the results as expected.

It does not display the delete buttom under the pictures within the album.
I am signed in as a Manager role. When I click on Edit Album link. i see the fields where i can upload new pic in the album , and it does not display any existing pics.

Here is my code in Default.aspx in PhotoAlbums Folder

Code:

protected void ListView1_DataBound(object sender, EventArgs e)
    {
      if (!string.IsNullOrEmpty(DropDownList1.SelectedValue))
      {
        EditLink.NavigateUrl = string.Format("~/ManagePhotoAlbum.aspx?PhotAlbumId={0}", DropDownList1.SelectedValue);
        EditLink.Visible = true;
      }
      else
      {
        EditLink.Visible = false;
      }

Here is the code in ManagePhotAlbum.aspx
I debugged this page by putting a break point on switch statement, and saw that it does not go pass the switch statement, that means the deletebutton visible is not executed at all.

Code:

protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
  {
    switch (e.Item.ItemType)
    {
      case ListViewItemType.DataItem:
        Button deleteButton = (Button)e.Item.FindControl("DeleteButton");
        deleteButton.Visible = Roles.IsUserInRole("Managers");
        break;
    }
  }

Thanks for your help in advance

Hi there,

Code:

 
deleteButton.Visible = Roles.IsUserInRole("Managers");

Could the difference in the name of the role (Manager versus Managers) be the problem here?

Cheers,

Hi Imar,

Thanks for the reply.
I mean I am signed in as a Manager user and "Managers" is checked for this user under Roles.
I also changed the code as you suggested to the following and saved/ran, but i get the same results.

Code:

deleteButton.Visible = Roles.IsUserInRole("Manager");

The switch statement fails so it does not even get to the above statement

Code:

switch (e.Item.ItemType)

Can you please suggest what else could be wrong?

Ah, so maybe the pictures are never bound. Could this be it:

Code:

 
"~/ManagePhotoAlbum.aspx?PhotAlbumId={0}"

Notice how you have Phot instead of Photo. If you use PhotoAlbumId in the target page, the album ID isn't passed correctly to the target page.

Hope this helps. You only posted a small bit of your code so I can only make some guesses. If this doesn't solve it, please post the complete code for the ManagePhotoAlbum.aspx page and the full URL you see in the address bar of the browser.

Thanks a lot Imar.
As you correctly pointed out. The problem was in PhotoAlbum/Default.aspx. I was missing a "o" after "t" in PhotoAlbumId={0}

Code:

EditLink.NavigateUrl = string.Format("~/ManagePhotoAlbum.aspx?PhotoAlbumId={0}", DropDownList1.SelectedValue);

It works great now. Thanks again

Sorry for resurrecting a long-dead thread, but I did the exact same thing! I left the 'o' off of 'Photo'.

Can you elaborate?
