detailsview

问题 I have a dropdownlist that is bound to a linq data source. This drop down list shows all the bowzer numbers except those whos status is set to false in the database. Suppose I have a record which was created earlier and now i want to edit the bowzer that is now set to false. I am thrown with this exception and i don't know how to deal with it. 'bowzerddl' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value Here is the code for my

问题 I'm new to ASP.NET, and I'm trying to figure out how to only show a chunk of code in the .aspx file if a value is not null or whitespace. Here's what I have, within a DetailsView : <asp:TemplateField HeaderText="Phone"> <EditItemTemplate> <asp:TextBox runat="server" ID="txtPhone" Text='<%# Bind("Phone") %>'></asp:TextBox> </EditItemTemplate> <ItemTemplate> <a href="tel:<%# Eval("Phone") %>"> <i class="icon-phone"></i> <%# Eval("Phone") %> </a> </ItemTemplate> </asp:TemplateField> I want to

问题 I am looking for a way to easily copy the file details that appear in a Windows Explorer (details view) and paste it as tabular text. Ideally, the procedure would be to select some files in an Explorer, make a choice in the context menu (or use a shortcut key), and the list would be copied to the clipboard. When pasting, the tabular format would be preserved so that Excel would recognize the columns or Word keep tabs (or create a table). I would like to have a solution that transfers the

问题 im trying to make a method that creates a List with the name of all the child controls of a DetalsView that are of type string. The closest i got was: foreach (Control c in dv.Controls) { if (c is Label) { controlsToCheck.Add(c.ID); } } foreach (string s in controlsToCheck) { Label lbl = (Label)dv.FindControl(s); if (lbl.Text == "") { lbl.Text = "None"; lbl.CssClass = "bold"; } } However, all this does is iterate once in the first foreach, and then exit (ie. dv.Controls only returns one item)

问题 I reference a previous post: Focus lost on partial postback with UserControls inside UpdatePanel where an excellent solution works perfectly for web-page controls within a form. However, I have placed my UC inside a detailsview template-field (for Edit+Insert). The UC contains an UpdatePanel needed to adjust the text-formatting and control's style(s) following the TextChanged event of the UC-textbox (AutoPostback=True) during the Edit-mode and Insert-modes of the DetailsView. As such, when

问题 I am developing an App with content that is crosslinked to other content. The App contains 5 Tabs. Each Tab has it's Tableviews and detailsviews. From the detailview of a Tab, one can proceed to other items from another tab. For Example: Tab 1 > TableView List Categories > TableView List Items > DetailView > TableView crosslinked Items > Tab 2 > DetailView (Hope that makes any sense! :D) When I activate the Tab 2 by tabbarController.selectedIndex = 1; it doesn't open the requested detailview

问题 I have a1.html, a2.html, b1.html, b2.html as local resources within app. I am having trouble loading these html files using plist and tableview into detailview's webview PLIST topics.plist <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>HN</key> <array> <dict> <key>Name</key> <string>Boston</string> <key>File</key> <string>a1</string> </dict> <dict> <key>Name</key>

问题 .NET 4 ASP.NET I have a DetailsView that is displaying an entity framework record for a table that has a linked lookup table. I have an asp:BoundField with the datafield set as "linkedTable.Field" and it displays a value. <asp:BoundField DataField="linkedTable.Field" HeaderText="linkedTable.Field" SortExpression="linkedTable.Field" /> I am trying to use that value in an asp:TemplateField but when I try to get it using: <asp:TemplateField HeaderText="Field" SortExpression="linkedTable.Field" >

问题 I'm trying to bind a Dropdownlist to a Detailsview control in a page where the result of the second Dropdownlist depends on the first one. I could bind a single Dropdownlist to a Detailsview but if I add another Dropdownlist where the result depends on the first one the details view wont show anything unless you refresh the page. So is there any way I could post the result of the detailsview automatically if the second dropdown is selected? I'm currently studying this but I couldnt get it.
