  1. POASP.NET: Attribute passed to ascx descends to top-level control but not nested control
    text
    copied!<p>In my ASP.NET project (VB.NET) I have a self-coded user control called DocumentDisplay that I invoke with a TargetWebPage attribute:</p> <pre><code>&lt;uc1:DocumentDisplay ID="DocumentDisplay" runat="server" TargetWebPage="EntityDocumentUpload"/&gt; </code></pre> <p>The codebehind for the user control implements the public property TargetWebPage, and in the debugger I can see it is being set correctly. Also, in the user control (ascx) there is a yyySecureButton defined (line 9), which also has this public property defined in it, and this is being set as well. The problem is I need the property to descend all the way to the yyySecureCommandField defined (within the DomainGridView control) on line 25; this property is in the codebehind for that control as well, but it is not being set.</p> <p>Can I pass the TargetWebPage attribute to the yyySecureCommandField from within the markup? If not, how best to do it?</p> <p>The code below is identical to what I'm working with except that strings identifying my client have been changed to vvv, xxx, yyy, etc.</p> <p>Many thanks for any response.</p> <pre><code>&lt;%@ Control Language="vb" AutoEventWireup="false" CodeBehind="DocumentDisplay.ascx.vb" Inherits="zzz.DocumentDisplay" %&gt; &lt;xxx:ErrorSection ID="ErrorSection" runat="server"/&gt; &lt;div class="FieldGroup"&gt; &lt;fieldset&gt; &lt;legend&gt;Documents&lt;/legend&gt; &lt;xxx:InputField runat="server" ID="InputFieldDocumentType" FieldName="DocumentType" CssClass="DocumentField" SuppressRequiredIndicator="True" /&gt; &lt;xxx:InputField runat="server" ID="InputFieldDocumentName" FieldName="DocumentName" CssClass="DocumentField" SuppressRequiredIndicator="True" /&gt; &lt;div class="DocumentField"&gt;&lt;label&gt;Upload&lt;/label&gt;&lt;input type="File" id="DocumentUpload" runat="server" /&gt;&lt;/div&gt; &lt;div class="TableSectionCommandBar"&gt;&lt;vvv:yyySecureButton id="ButtonUpload" runat="server" SecurityMode="Action" Text="Add" CssClass="StandardButton"/&gt;&lt;/div&gt; &lt;div class="Spacer" /&gt; &lt;div class="TableSection"&gt; &lt;xxx:DomainGridView ID="GridViewDocuments" runat="server" AutoGenerateColumns="False" CssClass="StandardTable" DomainObjectName="zzz.Domain.Document,yyyLib" DataKeyNames="DocumentId" AlwaysRequiresDatabind="True" AllowSorting="True"&gt; &lt;Columns&gt; &lt;xxx:FieldDefinitionField FieldName="DocumentType" ShowToolTip="True" SortExpression="DocumentType" /&gt; &lt;xxx:FieldDefinitionField FieldName="DocumentName" ShowToolTip="True" SortExpression="DocumentName" /&gt; &lt;xxx:FieldDefinitionField FieldName="DocumentDate" IsReadOnly="True" ShowToolTip="True" SortExpression="DocumentDate" /&gt; &lt;asp:TemplateField HeaderText="Doc" ItemStyle-HorizontalAlign="Center"&gt; &lt;ItemTemplate&gt; &lt;asp:Hyperlink ID="LinkViewContentDocuments" runat="server" Visible="&lt;%#Not String.IsNullOrEmpty(DirectCast(Container.DataItem, DocumentInformation).DocumentFileName)%&gt;" NavigateUrl="&lt;%#ResolveUrl(String.Format(CultureInfo.InvariantCulture, ApplicationUrls.ViewEntityDocuments, DirectCast(Container.DataItem, DocumentInformation).DocumentId))%&gt;" ImageUrl="&lt;%#ResolveUrl(ApplicationUrls.PaperclipImage)%&gt;" ToolTip="&lt;%#DirectCast(Container.DataItem, DocumentInformation).DocumentFileName%&gt;" Text="&lt;%#DirectCast(Container.DataItem, DocumentInformation).DocumentFileName%&gt;" /&gt; &lt;/ItemTemplate&gt; &lt;EditItemTemplate&gt; &lt;input type="File" id="UpdateDocumentUpload" runat="server" /&gt; &lt;/EditItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;vvv:yyySecureCommandField SecurityMode="Action" EditText="Edit" UpdateText="Update" CancelText="Cancel" DeleteText="Delete" ShowCancelButton="True" ShowEditButton="True" ShowDeleteButton="True" /&gt; &lt;/Columns&gt; &lt;EmptyDataTemplate&gt; &lt;asp:Label ID="LabelNoEntityResults" runat="server" Text="There are currently no documents to display."&gt;&lt;/asp:Label&gt; &lt;/EmptyDataTemplate&gt; &lt;RowStyle CssClass="ItemRow" /&gt; &lt;HeaderStyle CssClass="HeaderRow" /&gt; &lt;AlternatingRowStyle CssClass="AlternatingItemRow" /&gt; &lt;PagerStyle CssClass="PagingRow" /&gt; &lt;/xxx:DomainGridView&gt; &lt;/div&gt; &lt;/fieldset&gt; &lt;/div&gt; </code></pre>
