Custom WebPart .LoadControl(.ascx) event not firing

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :SharePoint

I am creating a Webpart which loads a custom control (.ascx) in the CreateChildControls Event

        protected override void CreateChildControls(EventArgs e)

            _userControl = Page.LoadControl(@"/_controltemplates/ControlTemplates/CustomUserControl.ascx");
            _userControl.ID = "usrSearchResults";


In the codebehind of this user control (I am using the inherits model as in ASP.NET 1.1) I have an InitializeControls method which binds the eventhandlers to an already existing DropDownList on the user control.

Markup in the .ascx file
    <asp:DropDownList ID="ddlRegions" AutoPostBack="true" runat="server" DataTextField="Title"
        DataValueField="Title" EnableViewState="true">

EventHandling code in the code behind of the user control.  This code runs in every Page_Load event.

ddlRegions.DataBound += new EventHandler(ddlRegions_DataBound);
The problem is that when the selected values in the dropdownlist changes the event handler does not fire (a post does occur though).  Am I missing something here?

List Event Receivers firing for all custom lists

Hello, I have a site with two custom lists, and I have created an EventReceiver class to handle the ItemAdded event for custom lists. I have modified the EventReceiver's Elements.xml file to only handle items added to one of the custom lists instead of all custom lists, by changing: <Receivers ListTemplateId="100"> to <Receivers ListUrl="/Lists/MyCustomList">   however, when debugging, the ItemAdded method is being fired when an item is added in both custom lists. I have had to work around this by checking within the ItemAdded method for the list that fired the event:        public override void ItemAdded(SPItemEventProperties properties)        {            base.ItemAdded(properties);            if (properties.ListTitle.Equals("My Custom List")) { ... } I thought the ListUrl attribute of the Receivers element specifies the event to only fire for the specific list with that url? (see http://msdn.microsoft.com/en-us/library/ms431081.aspx). Is there somewhere else I should be checking?   Thanks

Custom event does not fire

Hello,I have a base server control class for all my user controls. Inside this class I have the following declaration:#region Event Handling Management public event EventHandler ItemSaved; public event EventHandler ItemCancelled; protected virtual void OnItemSaved(EventArgs e) { if (this.ItemSaved != null) { this.ItemSaved(this, e); } } protected virtual void OnItemCancelled(EventArgs e) { if (this.ItemCancelled != null) { this.ItemCancelled(this, e); } } #endregion Concrete user controls used in the application are used always inside a ModalPopupExtender object and the popup it is always handled with server-side code. This means that there are no controls binded to the OkControlID and CancelControlID properties of the ModalPopupExtender.The responsibility to show the Modal Popup is then given to the aspx that has code like thisin the ASPX file...<gsl:PhoneNumberUC ID="ucPhoneDetail" runat="server" />in code behind...protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { //Bind to the event handler ucPhoneDetail.ItemSaved += new EventHandler(ucPhoneDetail_ItemSaved); ucPhoneDetail.ItemCancelled += new EventHandler(ucPhoneDetail_ItemCancelled); } } protected void btnNewPhone_Click(object sender, EventArgs e) { //Show the Modal Popup this.mpePopupPhone.Show(

MouseUp event not firing on ActivityDesigner class?

I have a custom control derived from ActivityDesigner.  I'm basically retemplating the contol to give it a stylized look and feel ... I want to add the ability to change the Display Name by swapping out the TextBlock with a TextBox on MouseUP - but this event is not firing. I can handle the MouseDown event and it works OK, except it enters the Edit mode when dragging the activity around.  Is the MouseUp handled at the base level?  Is there a way to work around this? 

Creating a custom drop down field type with SelectedIndexChanged Event

Hi All, I am trying to create a custom drop down field type and I was able to acheive that using the MS link http://msdn.microsoft.com/en-us/library/bb861799.aspx. As per the link, once the custom field is created we can override the "Validate" method to write the Validation logic and that works fine for me too. However I am facing a challenge even before going to Validate . Let me explain my actual requirements here. I need to build a custom drop down field and expose the field to the user in "Edit Properties " Page of a document library. Along with this field, I will be having some OOB site columns in the Edit Properties Page (Ex: Title, Subject etc)  . When user selects a value in the drop down, I need to hide/show few OOB site columns based on certain criteria.  I am facing a challenge of how to capture the "SelectedIndexChanged " event for the Custom drop down field in Sharepoint (Can we wire the SelectedIndexChanged event to a custom dropdown field type) ? Is this acheivable in SP 2010 Custom field type ? If so, how can I do it ? Can any of you kindly help me here?   Regards, Yesh

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

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

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?

Sharepoint Event Handler not firing

I have written an event handler for an ItemAdded eventfor a document library. I am trying to read an excel file being uploaded and extract a value from it which I write to a list column for the item. I have this working properly on my development machine which is a Windows Server 2003 machine.However, on a production Windows Server 2008 machine, the event handler never fires. I am doing a simple write to a log file to test and see if it runs at all even if the Excel parsing does not work but I get no indication that it ran. The event handler is being registered with a feature that I am deploying. I have verified that the event handler is registered to the library by using the u2u Event Handler Explorer tool.Is there any way I can determine if my event handlers are even executing? How can I debug this?
