Site Pages don't show up in mobile mode

In Site actions, I get the regular URL and the Mobile URL - - I've created several aspx pages with aspx controls on them. Two pages have dropdownlists, textboxes and gridviews. One just has a regular HTML table with aspx buttons, with postbackurls. Any list I create shows just fine, but none of the content in my aspx pages show up in mobile mode. I can get a list of the page names (with the extensions) when I click on 'view All Pages', however, when I click on the links, the content in the page does not show. What are we supposed to do for pages like these, for mobile mode?

Want to show a group header item only when the group value changes

Hi,    We have a couple of reports that show lines for a customer order. We were told to add notes for each line that were entered in our oe portal so our manufacturers and shippers could see them. I've done this but the group header for an order ine is set to repeat so the note shows on every page.Each line can take up several pages due to the fact that lot pick information is displayed for each line.     When the notes are long, it can create a report that is very long, simply due ot the extra space need on each page. We would like the line note to to appear ONLY when the value of the line number changes and we are on a new line and not after. Is there a way to detect that the line group value has changed and to print the note then but not after until a new line number is reached?    Any help would be appreciated. fig000

Want to show FormView in Edit mode with specific table columns depending on their Genre??

hi, I have  a table in my database called "Profiles". This holds data on Female and Male personal characteristics. On my aspx, I have a formview in edit mode which is binded to an object data source with a GetDataByUserId Select method which retrieves data from the "Profiles" Table via a DAL. The "Profiles" table has some columns which relates to females only and some just males and some are generic to both. See example below     UserId - / of Type GUID GenreId /  of Type BOOL. Hip Size (For females) Dress Size ( For Females) ChestSize (For Men ) TrouserSize (For Men) Weight ( For both )   When the User logs in , they go to an update Page which has the Formview in Edit Item Mode and contains drop down Lists which are binded to the Users Selected Value. The DDL are in turn bound to their related table such as HIP, Dress, Chest, Trouser etc. Objective If a female user logs in I just want to show them the (Hip Size) DDL  and DressSizeDDL in the Edit item template of the formview and not the ChestSize DDL or  TrouserSize DDL. At present the GetProfileByUserId returns all colums from the table My question is how do I do this and just show DDL which are relevant to the Female or Male Only. In some cases the user may not have selected an item in the previous form so they could also be

Show all in BDC data item picker by default

I have one ADF where it actually, by default when opening, show all 5 items without having to enter any filter criteria, which is great!  I'm trying to reproduce it for another project and cannot for the life of me do it again and it's driving me crazy.  I'm sure I'm missing something, but not sure what it might be and have spent hours comparing the two files for any elements, attributes that I might be missing without success.  Any ideas would be appreciated.

How to show label when TreeView is empty?


Sometimes I feel that DataBinding and Triggers defined in xaml is just trying to fight me.

I have this really simple case where I have a UserControl with a TreeView and a TextBlock. I want to show the TextBlock only when the TreeView is empty.

In code this would be one or two lines of code, but I’m determined to hook it up in xaml, but so far, no matter what I try it doesn’t work.


I even tried to expose the Items as a property on the control class itself – but I could bind to that either.


How would you do this in xaml ?





Content Query Webpart to show edit item link field in SPS2010


I have a Content Query Webpart in SharePoint 2010 that I would like to surface Documents grouped by content type. I wish to show the edit form or view Properties link as part of the fields shown in the results. When the User clicks on this link, it should take him to the edit form or view Properties page for the document.

Any ideas?

How to bind to a WPF TreeView's selected item?



Most of you probably know the excellent MVVM WPF TreeView article by Josh Smith (http://www.codeproject.com/KB/WPF/TreeViewWithViewModel.aspx).

Using the Family Tree demo (Text Search), can someone explain me how to bind a control's property (let's say, a TextBlock's Text property) to the selected item's Name property (PersonViewModel.Name) in the treeview? In essence, if the user clicks on "Sarah Applifunk", the TextBlock would show "Sarah Applifunk". Then if the user clicks on Maurice Winkleford, the TextBlock would update as such.

Of course I would like the TextBlock to look somehow like this:

<TextBlock Text="{Binding SelectedPerson.Name}" />

This *used* to work in my application using the IsSynchronizedWithCurrentItem="True" using lists, but the TreeView is somewhat more complex, isn't it?

CQWP results show only in Edit Mode



I added a CQWP to aggregate all Tasks within my site collection. It all works fine in Edit Mode and the correct tasks are displayed (it shows only the current user's uncompleted tasks).

However, as soon as I Exit Edit Mode the results disappear and the Content Query Web Part tells me "No items available". I switch back to Edit Mode: the items re-appear.

Any ideas what I am doing wrong?
