tabcontrol - owner must be set before initialize

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :ASP.Net
Hi all, I have a problem with scriptmanager, master page and the tabcontrol. If I stick the scriptmanager on the master page every ajax control works fine except for tab control. It (sometimes) gives an "owner must be set before initialize" error - all other ajax controls on the page do work however. If I put the scriptmanager the same page as the tab control all works fine. Anyone got any ideas on this. Google shows up zero hits on this error message. I really don't want to have to remove the scripmanager from the master page.  thanks

Owner-drawn ListView and nonstandard subitem size: selection problems.

Hello, I have a ListView whose first column is owner-drawn and items can be selected (I had to jump through hoops to draw the focus rectangle correctly). The problem is, my custom drawing displays the text in a wider font than normal, and only for this column. And when I click an item to select it, the right part of the text does not react, because the listview doesn't "know" there is text there (since it "thinks" the text is smaller). How can I correct this? Is there a "hit test" or "measure item" event or something, to tell the list view to consider a wider zone for clicks?

How to determine if current SQL User is admin or owner?

I wish to determine, from my C# application, if the current user has admin or owner rights to the database they are connected to. I beleive I have all the information required: Servername Database name Windows/Database auth username (If database auth) password (if database auth) I'm trying to find a way that using the smo objects (smo.user), but as of yet I cant quite work it out: - How to get the appropriate user - How to determine if that user is an admin/owner. Any tips would be appreciated. If I have posted to the wrong forum, let me know - I couldnt find one that was obviously more appropriate. Thanks.

Initialize snapshot fro alternate location - multiple .bcp files for an article

I have to replicate over 50GB of data over a slow network.  I did not use the option to initialize snapshot from database backup because the replication articles contain row filters.  If I do that, I'll have to run a lot of scripts to remove the data and other unnecessary database objects on the subscriber. Instead, I created a workaround.  On the publisher, I first create the actual push subscription to the target subscriber on the publication.  This subscription is set not to initialize from snapshot.  I then created a second push subscription on the same publication, but the subscriber is a random database on the publisher server.  This second subscription is a dummy subscription set to initialize from snapshot - the purpose is to generate the necessary snapshot files.  I then reinitialized all subscriptions and generate the new snapshot files. On the subscriber, an empty database is created with the same tables as the publisher database.  I created an identical publication on this empty database, and a dummy push subscription on the target subscriber.  The subscription is reinitialized, and the snapshot files on the empty database is created.  These dummy snapshot files are then overwritten with the actual snapshot files created on the publisher, and then I synchronize the the dummy subscriptions with the actual sn

Why is there no wizard control in WPF? Is there an easy way to create one, like with the TabControl

Hello, First, NO THIRD PARTY PRODUCTS!  In my search, it seems like anyone asking for a wizard control is sent to a third party to buy it.  I have no interest in buying a third party product, so if you are one of those that would suggest it, please don't, I'm simply not interested. If my understanding of page framework is correct, that is, the page is within a separate XAML file and the events are handled via its code behind, then I am not interested in such a scenario.  Nor am I interested in any fancy plumbing to make page framework work the way I want. All I want is the simple wizard control.  I'm amazed that such an important function was left out of WPF, especially since the TabControl is so close to being a Wizard Control. I'm thinking that the TabControl should be able to be made to function like a wizard, but my search finds nothing of any value.  Is the TabControl not suitable to be made to function like a wizard? Any help (other than third party products) would be greatly appreciated. Regards, Robert

The application failed to initialize properly (0xc0000006)

Hi, I have been trying to solve the above message when executing an application build with Microsoft Visual C# 2008 and Net Framework 3.5. I execute the application remotely on a cmd archive using \\server\share\app.exe The only acceptable solution I have found is http://social.msdn.microsoft.com/Forums/en-US/netfxbcl/thread/938b9bed-f317-4cca-9ec2-b6e8105f629b/ but it does not work. I executed the following command on the remote folder C:\Windows\Microsoft.NET\Framework\v2.XXXX\ caspol.exe -m -ag LocalIntranet_Zone -url file:\\server\Share\* FullTrust and it says ok, but it does not work neither. One thing to notice is that if running \\server\path\app.exe and change to \\server\path2\app.exe then it works!! Any advise? Many Thanks. Regards, Salva    

MVVM. Access TabControl->TabItems from ViewModel

Hi Folks,   Well, I just start to use MVVM, and I want to migrate functionality from my old non mvvm project to my new mvvm project.   The problem is the following one: In my old app (wizard application), I use tab control. And I have such things as States there. For this purpose I use StateMachine approach: My tab control looks like:   private void sm_StateChanged(State current, State previous, State next) { switch (current.Name) { case StatesNames.WELCOME_SCREEN_STATE_NAME: MainTabControl.SelectedIndex = 0; break; case StatesNames.SERVER_SUMMARY_SCREEN_STATE_NAME: MainTabControl.SelectedIndex = 1; preCertificationTabControl.SelectedIndex = 0; break; case StatesNames.SERVER_DEFINITION_SCREEN_STATE_NAME: MainTabControl.SelectedIndex = 1; preCertificationTabControl.SelectedIndex = 1; break; case StatesNames.UPGRADE_PRECERTIFICATION_SCREEN_STATE_NAME: MainTabControl.SelectedIndex = 1; preCertificationTabControl.SelectedIndex = 2; break; case StatesNames.PRECERTIFICATION_SCREEN_STATE_NAME: NavigationStateMachine.GetInstance().SwitchToNextState(); break; } } Well, as you can see, I need to access my tabControl to indicate states :( but it is not correct from

SharePoint Designer 2007 Workflow needs to initialize lookup field value and store it

This is for a governance tracking list. I have two tables: Roadmap and Roadmap Status In Roadmap, there are two fields of interest that are lookup fields to Roadmap Status:Title they are Status and OldStatus When an item is entered in Roadmap, I want to force the initial Status to "Submit" from Roadmap Status. I don't see any way in my workflow to to lookup that item in Roadmap Status and place the pointer (I'm assuming it is a GUID) into the field. The value is also stored in OldStatus to catch changes as I'm trying to force order of status in a few cases but not all. I'm doing it with a Lookup instead of Choice because the business tends to change the terminology they like and this way I don't change it in several places plus it allows them to change it in the list instead of someone changing the list field values. I've seen several places on the forum where people have a similar problem and Lambert Qin has given an answer but it never fits this scenario exactly. Do I have to go back to Choice columns? I only have Designer and would rather not have to learn another tool for a simple SharePoint implementation. Thanks for any help!

TabControl + Hot Keys?

Hi all. It seems that when setting up a tab control page's tab caption I can add a "&" to the string and see the underline appear on the next letter indicating that you can use that letter as a hot key to switch to a particular tab. However, the hot key doesn't actually work. Is alt+<hotkey> functionality not supported for a TabControl in .Net?

No CacheMiss Event When Calling SP With No Owner - Applies to 2005?

Hi, As outlined in knowledge base article 263889 (Description of SQL Server blocking caused by compile locks http://support.microsoft.com/kb/263889) it says you should specify the owner when calling a stored procedure to reduce compile locks.  I've tried this out in SQL Server 2000 by calling a stored procedure without an owner.  As expected in the profiler I can see a CacheMiss then a ExecContextHit. However, if I try exactly the same thing in SQL Server 2005 I never see a CacheMiss event (unless the execution plan needs to be created), I always see a CacheHit first.  Is this something that's been improved in SQL Server 2005?  The knowledge base article says it applies to 2005 at the foot of the page but I can't see it. Thanks for your help.
