How To Conditionally Show ListViewByQuery On Custom Page


I would like to only show a ListViewByQuery control on a custom page if the query contains some data. Currently if the query returns no data it is still rendered on the page with the comment "There are no items to show in this view".

The following code is my query code:

querySM.ViewFields = "<FieldRef Name='AssignedTo'/>" +
                  "<FieldRef Name='RequestSMReviewerComments' />" +
                  "<FieldRef Name='WorkflowOutcome' />";

        sQueryStr = "<Where>" +
                 "<And>" +
                  "<IsNotNull>" +
                   "<FieldRef Name='RequestSMReviewerComments' />" +
                  "</IsNotNull>" +
                  "<Eq>" +
                   "<FieldRef Name='WorkflowInstanceID' />" +

Retain DropDown,TextBox's previously selected values after redirected from another page.


 Hi People, How are you all doing?

I have 2 pages one is SearchPage & It has DropDowns, textboxes to specify the search criteria. From the search result the user is redirected to another page when he clicks the hyperlink in the search result  where he fills in the information and again redirected to SearchPage. Now the SearchPage is posted back with no state i just want to retain the search criteria and display when user comes back. Please give me some suggestion how to get this done. I've used ViewState to save the values and check them in Page_Load but they are null.   



 Update: I've come up with this code. But the problem is The values are being retained but the Button_Click event is not being handled properly. When i Check the code even after this "DropDownList1.SelectedValue = Session["Name"].ToString();" DownList1.SelectedValue is EMPTY"" samw with DropDownList2 . please Suggest something


    protected void Page_Load(object sender, EventArgs e)
        if (IsControlsEmpty())
            if (SessionExist())
                DropDownList1.SelectedValue = Session["Name"].ToString()

How show the computer user into a label in a master page

Why does RowLock result in a Page Lock

Hi, I am having a problem where even though I have indicated a rowlock it results in a page lock and a subsequent process is unable to access the table till the first process has commited.   Sample code is below.   Process 1 Begin Transaction SELECT EmpName FROM fEmployee WITH (ROWLOCK) WHERE EmpNo = 1 PRINT fEmployee.EmpName -- will print 'Sam' UPDATE fEmployee SET EmpName = 'Bob'  WHERE EmpNo = 1 .... .... .... Lots of other related processing takes place here and then finally COMMIT TRANSACTION Process 2 Begin Transaction SELECT EmpName FROM fEmployee WITH (ROWLOCK) WHERE EmpNo = 2 PRINT fEmployee.EmpName -- will print 'Rick' UPDATE fEmployee SET EmpName = 'Paul'  WHERE EmpNo = 2 .... .... .... Lots of other related processing takes place here and then finally COMMIT TRANSACTION When I run process 1 and process 2 at the same time, till process 1 commits the transaction, process 2 does not perform the Select and print the name. Why is this the case as they are both selecting different records and the Select has specifically indicated a RowLock. What I noticed was that when the rows are in the same page this problem occurs, while if the records are in different pages (assuming the data is large in the table and the gap between the empno's are large) it does not occur. Any help appreciated. Thanks

I looked through the library settings but didn't find anything to turn on this feature. Does anyone know how to do this or if this feature was even included in SharePoint 2010? Thanks.

We installed both WSS and MOSS SP2 and had planned to follow the manual fix for the known issue that the patch unexpectedly activates a trial expiration.  However, the textbox to enter the product key is read-only.  We have tried accessing this page using the normal administrator credentials as well as the farm account; no success.The SP2 issue and manual fix is detailed here, http://support.microsoft.com/default.aspx/kb/971620We were able to experience this problem on a farm running the Feb 2007 cummulative patch (version so it's not related to the SP.  But running the SP increasing the need to find the fix.Any help is appreciated,J.

Web Part Page doesn't show current navigation

Hi! I'm having a problem with the navigation of web part page in Sharepoint 2010. For starters I need to say that I am a web designer and learning to brand Sharepoint 2010 wich means I'm not that tech-savvy so bear with me. We have created an intranet publishing site with Sharepoint 2010 and I have designed a custom master page with styles through Visual Studio 2010. The intranet site looks fine with the new design and I got navigation working with fly out menus, semantic subpages etc. The problem is: when I create a normal page the current sub-navigation is shown and it even shows my created web part page and all is fine, but once I go to this web part page, the left/sub-navigation disappears and I have no idea how to bring it back. The web part page uses the same master file as every other page. Everything with the the layout stays the same as my masterpage, except for the menu wich disappear so I thought it might be some property missing on the sub-navigation. Or do I need to edit something in the web part page layout in the gallery?: Master Page Gallery > BlankWebPartPage.aspx If so can I do it from Visual Studio? Here is the code for the left navigation menu: <!-- styles needed to have left nav to the left of the main area --> <div id="s4-leftpanel" class="s4-notdlg"> <!-- The quick launch bar / left navigation
