C# - ListView: Display Data Divided Into Groups?
May 3, 2010
I would like to display the contents of a DataTable, divided into several groups depending on the value of one of the columns. So, if I have a DataTable (from SQL query) with:
GroupID Name Description
1 foo bar
1 one two
2 some thing
I would like to place all records containing GroupID 1 in one div, all records with GroupID 2 in another div, and so on. How can I do this?
I'm writing in ASP.NET 4.0, with C# codebehind.

I am having trouble finding how to solve the following issue :
I am using nested listviews to display Sales and Sales details.
The main ListView displays General Information about Sales and the child ListView displays the detailed information about one sale. the child listview is shown only when the user clicks on a link (see included code, DataBind is made on PageLoad) :
ASPX Markup Code :
[Code]....
C# Behind Code :
[Code]....
If I removed the datapager part, I can manage show/hide the child list view on the button click event. but if I want to use the DataPager with the PreRender event handling, the child listview is not longer shown on button click.

I am "DomainMyDomainUserName" If I do this:
[Code]....
I can access the website I've created on my local machine in debug mode; and with my domain account as a local administrator, if I do this:
[Code]....
I can still access the website; and with my domain account in a Domain Group named "DomainDomainLocalSecurityGroup", if I do this:
[Code]....
I can still access the website; HOWEVER, if I create a Local Group on my machine named "LocalMachineGroup" and I add "DomainMyDomainUserName" to this group and I do this:
[Code]....
I get an Access Denied error trying to access the website. What I want to do is, have a group on my local machine (for testing), on a test web server, and on a production web server named "MyWebsiteUserAccess" with the same Domain Group (filled with Domain Users allowed access to the site) in all of these local groups; so that when I test the web application on my local machine, on my test web server and on my production web server, I don't have to change the Web.config file to have it work on each AND if the Domain Group name ever has to change, it won't affect access to the website.
What am I overlooking or is this even possible to do this way? I understand that there is a way to do Role Management through ASP.NET but I don't understand that well enough yet to implement that (and will probably go that route once I've done the research on how to best implement it for purpose of access control of this intranet site).

I have a user that when I attempt to enumerate her groups using either System.Security.Principal.WindowsIdentity.GetCurrent().Groups on user's computer
or System.Web.HttpContext.Current.Request.LogonUserIdentity.Groups on the IIS server, I get a list of their old groups, not their new. I have checked the DC that they authenticate to and the ASP.NET page is running inside a SharePoint instance so the LogonUserIdentity most like is being provided from there Kerberos ticket.
Should I be looking up the groups directly from the AD instead of relying on the WindowsIdentity or LogonUserIdentity?

i have a code to get the groups a user belongs to.
try
{
DirectoryEntry adRoot = new DirectoryEntry(string.Format("WinNT://{0}", Environment.UserDomainName));
DirectoryEntry user = adRoot.Children.Find(completeUserName, "User");
object obGroups = user.Invoke("Groups");
foreach (object ob in (IEnumerable)obGroups)
{
// Create object for each group.
DirectoryEntry obGpEntry = new DirectoryEntry(ob);
listOfMyWindowsGroups.Add(obGpEntry.Name);
}
return true;
}
catch (Exception ex)
{
new GUIUtility().LogMessageToFile("Error in getting User MachineGroups = " + ex);
return false;
}
the above code works fine when i have to find the groups of a local user but
for a domain user it returns a value "Domain User" which is kind of wierd as it is a part of 2 local groups.
Research
I did some finding and got that i am being returned the primary group of the domain user
called "Domain User" group
but what i actually want is the groups of the local machines the domain user is a part of... i cannot get that.. any suggestions
another code using LDAP
string domain = Environment.UserDomainName;
DirectoryEntry DE = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure);
DirectorySearcher search = new DirectorySearcher();
search.SearchRoot = DE;
search.Filter = "(SAMAccountName=" + completeUserName + ")"; //Searches active directory for the login name
search.PropertiesToLoad.Add("displayName"); // Once found, get a list of Groups
try
{
SearchResult result = search.FindOne(); // Grab the records and assign them to result
if (result != null)
{
DirectoryEntry theUser = result.GetDirectoryEntry();
theUser.RefreshCache(new string[] { "tokenGroups" });
foreach (byte[] resultBytes in theUser.Properties["tokenGroups"])
{
System.Security.Principal.SecurityIdentifier mySID = new System.Security.Principal.SecurityIdentifier(resultBytes, 0);
DirectorySearcher sidSearcher = new DirectorySearcher();
sidSearcher.SearchRoot = DE;
sidSearcher.Filter = "(objectSid=" + mySID.Value + ")";
sidSearcher.PropertiesToLoad.Add("distinguishedName");
SearchResult sidResult = sidSearcher.FindOne();
if (sidResult != null)
{
listOfMyWindowsGroups.Add((string)sidResult.Properties["distinguishedName"][0]);
}
}
}
else
{
new GUIUtility().LogMessageToFile("no user found");
}
return true;
}
catch (Exception ex)
{
new GUIUtility().LogMessageToFile("Error obtaining group names: " + ex.Message + " Please contact your administrator."); // If an error occurs report it to the user.
return false;
}
this works too but i get the same result "Domain Users" . Please can some1 tell me how to get the local machine groups...?

I have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.
<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />
Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>
Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?

I have a ListView that populates and displays a user's data (via a profile system in VWD 2008) during Page_Load and also when I go from the EditItemTemplate to the ItemTemplate.
When I go to the edit screen again, my DropDownList and RadioButtonList controls display the first items in the corresponding tables instead of the correct profile values.
I don't understand why the controls populate correctly the first and second times but not on the third time (that's right, the third time is NOT a charm).

I am using a nested listview to display a seperate grid for each group of data returned from my db query. To get this working, I have adapted a piece of code to group the data prior to it being bound:
[Code]....
I am then using the following html markup:
[Code]....
[Code]....
This works as I want it to however some of the fields within the nested table need to be formatted as currency so I am trying to use Eval and {0:c} to do this however the moment I use Eval, the data items cannot be found
DataBinding: 'System.Data.DataRow' does not contain a property with the name '0'.

I'm trying to use a ListView to display product specs. I also want to display the group headings such as "Dimensions", "Input Ports", etc.
How do I display these group headers? My code below lists the specs but doesn't show me the header. If I put some static text however, that shows up. What am I doing wrong?

I 'm populating the images in the listview control from the database.... but now i want to get only broken images from the server(eg images which are not showing, cross box) so my user can fix those images in the server. I want to put a checkbox in the search criteria so either they can see all the images from the table or only broken images.Is there any way of doing that from asp.net or with javascript.

<asp:ListView ID="ListView1" runat="server">
<LayoutTemplate>
<ol>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</ol>
</LayoutTemplate>
<ItemTemplate>
<li>
<%# Eval("PersonName") %>
<%# Eval("PersonAddress")%>
</li>

The problem is the address is not aligned depends on the person's name length.
I want to have 2 columns aligned and with horizontal and vertical grid lines. Can I do that?

I have a ListView connected over SqlDataSource control.
Inside my DB Table I have 2 Columns:
Column 1: ItemSent (Bit) TRUE or False and
Column 2: ItemPaid (Bit) TRUE or False.
Now in each row in my ListView I have to display 2 Images depending on Column1 and Column2
This part should be something like this:
If ItemSent = 1 Then
Img1.ImageUrl = "SentOn_png"
Else
Img1.ImageUrl = "SentOff_png"
End If
and same for the 2nd image
If ItemPaid = 1 Then .
