User Control not accessing the value of the properties send to it from the aspx page.


I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as


<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>


but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong

the problem is eval is not passing the value to usercont

System.Messaging - Error accessing properties of remote private queues - "UnsupportedFormatNameExcep

I'm having some difficulty accessing private queues on a remote machine, but no trouble using remote public queues or private queues on a local machine. Calling: System.Messaging.MessageQueue.GetPrivateQueuesByMachine("machine"); ..succesfully returns the array of private queues on the remote machine.  However, trying to access nearly all of the properties on these MessageQueue objects returns: MessageQueueErrorCode: UnsupportedFormatNameOperation Message:"The specified format name does not support the requested operation. For example, a direct queue format name cannot be deleted." I have no trouble accessing queues created identically on the local machine using GetPrivateQueuesByMachine("."), plus accessing public queues using GetPublicQueuesByMachine("machine") also returns MessageQueue objects that are useable. The FormatName returned appears to be valid, as you would expect from queues retreived via GetPrivateQueuesByMachine().  e.g: FormatName:Direct=OS:machine\\private$\\example ..so I think the error message returned may be somewhat spurious. The permissions on the queues all appear to be set correctly.  I had even attempted allowing "Full Control" to "Everyone" on these queues as an experiment, with the same results. Any ideas for other things I might try? p.s. I am running Windows XP SP2, using .NET 2.

Serializaing/deserializing XOMLs with custom activities that have properties of ISerializable types

I have custom activities that have dependency properties of types that implement ISerializable. When they are serialized/deserialized to XOML, the ISerializable-implied functionality is ignored and the standard reflection-based SerializableAttribute behavior is invoked. This poses a serious problem since the types require precise control over their serialization to ensure that proper internal state is maintained across serialization boundaries. I am aware of the WF custom serialization methods as mentioned in Tom Lakes' blog post, but they seem to require the DesignerSerializerAttribute attribute on all custom types. This is a problem because the types are business objects shared across many (non-WF) applications and they are part of a seperate code base to which I have no access. Is there a different method for getting custom serialization? And what is the reasoning behind the WF team choosing to ignore the very basic ISerializable attribute which is supported by every other .NET API across the framework? Thanks in advance.

ListItem Dynamic DropDownList based on custom list entries.

I utilized the following solution to get the drop down list on the page and populate it dynamically, but it doesn't save the selected value back to the SPListItem object. Does anyone have a better solution possibly for this? http://geekswithblogs.net/SoYouKnow/archive/2010/01/21/sharepoint-populating-drop-down-list-field-with-data-from-different.aspx

Overriding web.config in sharepoint webpart/using custom membership in web part

I'm developing a web part for MOSS 2007. The web part is being deployed to a web application which utilizes forms-based authentication, and role/membership providers to control users. The membership table has been edited to include addition user info (I am aware, that this isn't the best way to handle additional user, i.e. profiles etc., however, this is a requirement from another department). Since my web part needs to access this information, I was thinking of implementing a custom membership provider. So far I've followed: http://msdn.microsoft.com/en-us/library/6tc47t75.aspx and I've got my custom membership class, and a very stripped down membershipprovider-class. But how do I enable/use this membership provider in my web part? I've tried creating a simple web.config in the "WebPartCode" folder of my solution, next to my webpart code file, with connection string and membership provider tags. But I don't even really know how to build/reference/use the membership provider itself, so I don't know what else I need to do. I've built a C# class library project with the two classes (membershipprovider and custom membershipuser) and compiled it and installed it in the global assembly cache - is this correct? and how do I access them from here? Hope someone can help

Accessing a row's dropdownlist values AFTER the gridview control is in Edit mode

Hello, I have a gridview control. When it goes into Edit mode, there are 3 dropdownlists in one cell that are populated by separate stored procedures during the RowDataBound event. The 1st dropdownlist's value is used as a parameter to determine what the 2nd dropdownlist is populated with. The 2nd dropdownlist's value is used as a parameter to determine what the 3rd dropdownlist is populated with. Everything works fine when the row is first put into Edit mode. While I'm in Edit mode and I change the selection in the 1st dropdownlist, how do I access the control so I can feed this new parameter to the 2nd dropdownlist? I have the first 2 dropdownlists set for AutoPostBack so that the Page_Load event is fired when the user changes a value. I know how to get access to these controls via the FindControl method when the row is being databound but how do I find the control during the Page_Load event? Thanks for any help!!!   Penny

Cannot enable Ribbon Edit Tab buttons and "connect" them to a list item in my custom webpart

I have one list with some custom fields and I want to develop a custom page. So, I created an ASPX page and added my custom webpart. This webpart has just a RichTextField, in edit mode, "linked" to one item of the list, like below: SPSite _SPSite = SPContext.Current.Site; SPWeb _SPWebProjects = _SPSite.OpenWeb("/Projects"); SPList _SPListProject = _SPWebProjects.GetList("/Projects/Lists/Project"); int _ID = Convert.ToInt32(this.Page.Request.QueryString["ID"]); RichTextField _RTF = new RichTextField(); _RTF.ID = "RTF"; _RTF.ControlMode = SPControlMode.Edit; _RTF.FieldName = "History"; _RTF.ItemContext = SPContext.GetContext(HttpContext.Current, _ID, _SPListProject.ID, _SPListProject.ParentWeb); _RTF.RenderContext = SPContext.GetContext(HttpContext.Current, _ID, _SPListProject.ID, _SPListProject.ParentWeb); this.Controls.Add(_RTF);   Then, I "turned on" the edit tab on the ribbon by doing the follow: protected override void OnPreRender(EventArgs e) { SPRibbon _CurrentRibbon = SPRibbon.GetCurrent(this.Page); _CurrentRibbon.TrimById("Ribbon.WebPartPage"); _CurrentRibbon.MakeTabAvailable("Ribbon.ListForm.Edit", string.Empty); _CurrentRibbon.MakeContextualGroupInitiallyVisible("Ribbon.ListForm.Edit", string.Empty); _CurrentRibbon.Minimized = false; _CurrentRi

Make a webpart properties customizable only by an Administrator

Creating Custom ASP.NET Control for use on a SharePoint 2010 OOTB WebPart

I am currently trying to develop a custom asp.net control that can be deployed to SharePoint 2010 and then included on something like a New item form. I have been able to build the control as part of a webpart but it needs to be done as a stand alone control that can be used on various webparts including the out of the box webparts like the WebPartPages:DataFormWebPart. Are there any good examples of building a custom control, deploying it to SharePoint and then using SharePoint designer to add that control to an existing web part?

Search - How to remove a meta tag ... / custom column is not showing up in Crawled Properties after

Hi I got the following warning after I crawled a site. Info out of Crawl Log: "The content for this address was excluded by the crawler because this item was marked with a no-index meta-tag. To index this item, remove the meta-tag and recrawl." Sound easy but I don't no where I could do it. The other problem is that I try to get a custom column from a custom list showing up in the crawle properties. I am using also a custom scope with the behavior "INCLUDE" ... In MOSS 2007 it was a lot simpler ;-) Thanks Regards MIA    

Problem with Content Query Webpart and Custom Userfields

Dear Community, I am using Sharepoint 2007's content query webpart to access content types from 2 lists each contained in a different sitecollection. To achieve this, I used this tutorial: http://www.heathersolomon.com/blog/articles/CustomItemStyle.aspx. The tutorial worked great. By using the property CommonViewFields and modifing the XML Stylesheets accordingly, i could access almost every field. Even User Fieldtypes like editor and author were accessible by adding (editor,User) or (author,User) to the CommonViewFields property. But when I tried to access the custom made userfield "Username" in the same way (adding Username,User to the property), the webpart threw an error and couldn't be displayed anymore. When I changed it to Username,Text , no error occured but it naturally didn't show up, since it is the wrong fieldtype. I hope some of you can help me, since all my researches on this topic only brought up some more people with the same problem, but no solution to it. Thanks in advance, SoundofSilence

Searching for custom properties in a default search

Hi all, I have added some custom properties in to Manage User Properties in my User Profile Service Application. The issue I'm having is that I'm unable to obtain search results from these properties. For example, if in the Enterprise Search / People tab I enter "Dave" and click search, then I'll be presented with results of people who's name matches "Dave". If I enter "Information Technology" then I'll get a list of all users who's department is "Information Technology". So far we're okay! But let's go back to the custom property. Let's say it's called "Clients" and it is for storing client names against the staff profiles. If I search for "Microsoft" and a user has Microsoft in their client property then no results are found. I've created the managed properties in the Metadata Property Mappings of my search service application, done full crawls but nothing. If I search for "clients:microsoft" then I get results. So the question is how do I or is it even possible to get custom metadata properties to show up in a default search? Thanks!
