View 1 RepliesSo I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).
How can I hide some items in my menu if you are just a user & only appears if you log in as administrator? I would like to hide the siteadmin. Below is the code:
[Code]....
For example in my datalist if Eval("OptionJ").Tostring = Null I would like the function GetVisible to set visibility of the radio button to false like so:
<input name="Q<%#Eval("ID")%>" type="radio" value="J" visible="<%# GetVisible(Eval("OptionJ").ToString()) %>">
<%#Server.HtmlEncode(Eval("OptionJ").ToString())%>
</option><br />
I then have a codebehind function like so:
Protected Function GetVisible(ByVal Evalresult As String) As String
If Evalresult = Nothing Then
Return "False"
Else
Return "True"
End If
End Function
I have also tried checking EvalResult = String.empty
In the outputted html the visible status is being set to false...
<input name="Q3" type="radio" value="J" visible="False">
But it is still displayed on the page!
I have menu item on which come from website map. I have trimmed the main item of menu based on user roles.
Like i have one menu in which i have 5 reports i want to show 2 reports to agents and 5 reports to admin. how to apply roles on sub menu item.
I have a ListView control in Asp.Net WebForms which display a set of elements, I have at the end a "More" button like Facebook for example. During the postback I want to get from database another 10 elements (I have already displayed 10 and I don't want to retrieve them again)
Something like this.
foreach (var item in New10Items)
ListView.Items.Add(index,DataItem)
the problem is with DataItem, how to Bind it before add it? what is the best way of solving this?
I want to hide a column of ListView based on the role from the code behind. Here's the mark-up and the code:
<asp:ListView ID="lvTimeSheet" runat="server">
<LayoutTemplate>
<table id="TimeSheet">
<thead>
<tr>.....
But that column id="thDelete" is visible all the time. How do I go about hiding the column based on some condition from the code behind?
Listview and findcontrol ans show and hide my panel.
I would like to show a faq-area with many questions and answers. If the page was load, i will show only the questions. Now the user can click the button show, then my panel must be visible = true and the answer of the clicked question was shown.
How can I realize this?
My proposal is this code, but it does not run.

I have a custom menu, which leverages the standard asp.net sitemap. It works well but some of my pages are dynamically generated by URL rewriter, so they don't sit in the sitemap XML file. At the moment I rolled a custom solution which shows/hides menu items via CSS class and a programmatic check of the role that the user is in. It works ok until I visit a dynamic page that doesn't exist in the sitemap file. I've tried the "roles" attribute in the sitemap file with security trimming but it isn't working because I have a custom menu.
Is there a way I could leverage the roles attribute in the sitemap file to show/hide menu items for my custom control below, even when some pages are not in the sitemap? My menu control is below...
<div class="menu">
<ul>
<asp:Repeater ID="rpt" runat="server" DataSourceID="smdsMenuPrimary"
EnableViewState="False">
<ItemTemplate>
<li class="<%#GetDisplayClass((SiteMapNode)Container.DataItem)%>"><a href='<%# ((SiteMapNode)Container.DataItem).Url %>'><%# ((SiteMapNode)Container.DataItem).Title %></a></li>
</ItemTemplate>
</asp:Repeater>
</ul>
I need to know how to do what the following would intuitively do if it worked (imagine useGreek() and useNato() to be states that would be consulted once per load or postback):
<asp:radioButtonList id="rbl" runat="server" autoPostBack="true">
<asp:listItem value="alpha" text="Alpha" />
<% if(useGreek()) { %>
<asp:listItem value="beta" text="Beta" />
<asp:listItem value="gamma" text="Gamma" />
<% } else if(useNato()) { %>
<asp:listItem value="bravo" text="Bravo" />
<asp:listItem value="charlie" text="Charlie" />
<% } %>
<asp:listItem value="delta" text="Delta" />
</asp:radioButtonList>
(It will already be apparent that I'm not usually asked to write for IIS.)
Anyway, ASP.NET doesn't like code interleaved with list items, so this is a no-go. I imagine that there's some C#-based way to handle this somehow, but I've been trying for a few days now with no luck.
Also, just to be clear, I'm seeking a server-side solution here. I'm well-versed with jQuery, but we're trying to keep most of the processing of this particular form off the client.
I have a listview showing images like ImageViewer and I want to implement Drag-Drop behavior within ListView. how can i achieve the Srag-Drop inside the below kind of customized ListView.
<asp:ListView ID="lvPhotoViewer" runat="server" GroupItemCount="3" InsertItemPosition="LastItem">
<LayoutTemplate>
<table id="groupPlaceholderContainer" runat="server" border="1">
<tr id="groupPlaceholder" runat="server">
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<td id="Td4" align="center" style="background-color: #eeeeee;">
<asp:Image runat="server" ID="imPhoto" Height="100px" Width="100px" ImageUrl='<%# "~"+Eval("PhotoUrl") %>' />
<br />
<asp:Label ID="DefaultPhotIDLabel" runat="server" Text='<%# Eval("PhotoName") %>' />
</td>
</ItemTemplate>
<GroupTemplate>
<tr id="itemPlaceholderContainer" runat="server">
<td id="itemPlaceholder" runat="server">
</td>
</tr>
</GroupTemplate>
<InsertItemTemplate>
<td id="Td3" width="150px" height="150px" runat="server" align="center" style="background-color: #e8e8e8;
color: #333333;">
<asp:FileUpload ID="fileUpload" runat="server" />
</td>
</InsertItemTemplate>
</asp:ListView>
Code Behind:
public class ImageEntity
{
public string PhotoName { get; set; }
public int PhotoIndex { get; set; }
public string PhotoURL { get; set; }
}
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
IList<ImageEntity> imagesList = new List<ImageEntity>()
{
new ImageEntity(){ PhotoName="House1", PhotoIndex=1, PhotoURL= @"ImagesHouse-01.JPG" },
new ImageEntity(){ PhotoName="House2", PhotoIndex=2, PhotoURL= @"ImagesHouse-05.JPG" },
new ImageEntity(){ PhotoName="House3", PhotoIndex=3, PhotoURL= @"Imageshouse.jpg" },
new ImageEntity(){ PhotoName="House4", PhotoIndex=4, PhotoURL= @"Imageshouse2.jpg" }
};
lvPhotoViewer.DataSource = imagesList;
lvPhotoViewer.DataBind();
}
}
I am trying to use checkboxes to select the items in a Listview. I have added a checkbox control in the , and they are displayed properly.
The problem is that Checked property never changes when I click on them. Why does this happen?
Here is the code:
<asp:ListView ID="ListView1" runat="server"
onitemcommand="ListView1_ItemCommand"
onitemdatabound="ListView1_ItemDataBound">
<LayoutTemplate>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />.......
I'm currently using a ListView in my webformsapplication. This ListView generates a table with (currently) three columns. "Username", "Organization" and "Locked". These are represented with string, string and checkbox respectively. The checkbox should postback on change...
Should I use <%# Eval("Username") %> or <asp:Literal blablah> to inject the data? This is more relevant for the checkbox... It seems very "dirty" to write <input type="checkbox" id="something" <%# if ((bool)Eval("Locked") == true) /* some unknown code for outputting "checked" */ ;%> />
Or should I use another container alltogether?
I'm having a hard time coming up with a good way to number the items in my paginated ListView. The solution I was using prior to adding pagination worked fine, but now the numbering doesn't persist between pages. If the first page is 1-10, the next page will also be 1-10 and so on. Obviously, it should be 1-10, 11-21, etc.
Is there an easier way to add numbering to ListView items that I'm missing? What's the best way to do this?
How can I hide a LinkButton in a ListView's ItemTemplate if the user is not logged in?

I have a listview that is bound to a datatable on the runtime. The listview has a <ItemTemplate> format which includes a lot of controls. On the page Load I do bind the listview to a datatable. Now, I want to add more ListView Items without databinding the whole listview and maintain the same ItemTamplate.
