Access The Group Of A Linq Group - By Query From A Nested Repeater Control?
Mar 26, 2010
I'm using a linq group by query (with two grouping parameters) and would like to use the resulting data in a nested repeater.
var dateGroups = from row in data.AsEnumerable()
group row by new { StartDate = row["StartDate"], EndDate = row["EndDate"] };
"data" is a DataTable from an SqlDataAdapter-filled DataSet. "dateGroups" is used in the parent repeater, and I can access the group keys using Eval("key.StartDate") and Eval("key.EndDate").
Since dateGroups actually contains all the data rows grouped neatly by Start/End date, I'd like to access those rows to display the data in a child repeater. To what would I set the child repeater's DataSource? I have tried every expression in markup I could think of; I think the problem is that I'm trying to access an anonymous member (and I don't know how.) In case it doesn't turn out to be obvious, what would be the expression to access the elements in each iteration of the child repeater? Is there an expression that would let me set the DataSource in the markup, or will it have to be in the codebehind on some event in the parent repeater?

i have the following objects:
Event:
- EventID (PK)
- GroupID (FK)
- StartDate
Group:
- GroupID (PK)
- GroupName
What i need to do is select the last 5 events for each group using LINQ to Objects. I tried starting with:
[Code]....
But i'm not sure how i only take the last 5 per group.
The simple way of doing this is to get the groups and then have a property on that which returns the last 5 events but if i databind this i will have to use a nested Repeater/ListView. Ideally i would like to have a row foreach event.

I'm currently learning entity framework (from the Julia Lerman book "Programming Entity Framework") and got really confused at the grouping part.
var contacts = from c in context.Contacts
group c by c.Title into myGroup
select myGroup;
This is supposed to return a Grouping<K,T> type, but the book didn't give an example on how exactly do I access this "contacts" query and I can't figure it out. When I did foreach(var contact in contacts), my "contact' variable has no knowledge of any of the properties of the Contact type (contact.FirstName etc).

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'.

Stack-Overflow :3 I've got a kind of hard-case question.
So I'll try clearly explain my idea with my poor english :/ need select to DataTable SOME values from ???_**GetDisplayData **procedure for each day of previos month (GROUP IT) where group rules for different columns is different
I need to select some values in stored procedure from other stored procedure like this :
SELECT X FROM Y_Procedure(@ProcedureParameters)Also I need to select from dynamic SQL Procedure like
Y_Procedure=@Y+'_Procedure'
SELECT X FROM Y_Procedure(@ProcedureParameters)
Also I need to load it to DataTable :-/INSERT INTO @Report (CellHorizontal, CellVertical, CellValue) --to TABLE
SELECT Date,X2,X3 FROM Y_GetDisplayData(@Param)
SET NOCOUNT OFF;
SELECT *
FROM @Report
GetDisplayData works as select with parameters and that doesn't returns SQL DataTable
And there is no way to recode GetDisplayData's procedures, it's just constant procedures for me.Finally I need to Group nodes from this table
INSERT INTO @Report (CellHorizontal, CellVertical, CellValue)
SELECT T1.Date,
IF ((Select grouptype...)=1) T1.X2 + T2.X2
ELSE IF ((Select grouptype...)=2) AVG(T1.X2,T2.X2),
IF ((Select grouptype...)=1) T1.X3 + T2.X3
ELSE IF ((Select grouptype...)=2) AVG(T1.X3,T2.X3),
(SELECT T2.Date,X2,X3 FROM Y_GetDisplayData(@Param) T2
WHERE T2.Date>T1.Date AND T2.Date>=T1.Date)
FROM Y_GetDisplayData(@Param) T1
GROUP BY EVERY DAY ???--and here is epic fail
I can make all stuff on asp server :And C# allows me to use something like SelectCommand = IzmProc + "_GetDisplayData"; And then I will work (select special data) with DataTables on ASP.NET Server but it's better to make all on SQL ... But looking like it's just unrealizable on SQL >_<
I gonna think about C# realization,but my code is very weird , got errors and doesn't works >_<
public static DataTable GetReport(string Param)
{
System.Configuration.ConnectionStringSettings connSetting = ConfigurationManager.ConnectionStrings["FlowServerConnectionString"]; [code].....

I have an ASP.NET 3.5 application using Windows Authentication and implementing our own RoleProvider.
Problem is we want to restrict access to a set of pages to a few thousand users and rathern than inputing all of those one by one we found out they belong to an AD group.
The answer is simple if the common group we are checking membership against the particular user is a direct member of it but the problem I'm having is that if the group is a member of another group and then subsequently member of another group then my code always returns false.
For example: Say we want to check whether User is a member of group E, but User is not a direct member of *E", she is a member of "A" which a member of "B" which indeed is a member of E, therefore User is a member of *E"
One of the solutions we have is very slow, although it gives the correct answer
using (var context = new PrincipalContext(ContextType.Domain))
{
using (var group = GroupPrincipal.FindByIdentity(context, IdentityType.Name, "DL-COOL-USERS"))
{
var users = group.GetMembers(true); // recursively enumerate
return users.Any(a => a.Name == "userName");
}
}
The original solution and what I was trying to get to work, using .NET 3.5 System.DirectoryServices.AccountManagement and it does work when users are direct members of the group in question is as follows:
public bool IsUserInGroup(string userName, string groupName)
{
var cxt = new PrincipalContext(ContextType.Domain, "DOMAIN");
var user = UserPrincipal.FindByIdentity(cxt, IdentityType.SamAccountName, userName);
if (user == null)
{
return false;
}
var group = GroupPrincipal.FindByIdentity(cxt, groupName);
if (group == null)
{
return false;
}
return user.IsMemberOf(group);
}
The bottom line is, we need to check for membership even though the groups are nested in many levels down.

I've a table with datetime null field in sql server. I'm trying to group the results based on the year in that field. But, when I wrote linq query, I didn't get intellisense for Year when I type that field. It only shows HasValue and Value. I think because it is converted nullable type. How do I do the grouping in this case?

I am trying to translate this:
SELECT IDNum, Max(Convert(varchar(20), (TimeOut - TimeIn), 108))
FROM IO_Times Group by IDNum
order by Max(Convert(varchar(20), (TimeOut - TimeIn), 108)) desc";
Into LINQ in C#. The above returns a list of the maximum value of (TimeOut-TimeIn) that corresponds to each unique IDNum (There are multiple TimeOut-TimeIn values for every IDNum).Here is what I am trying now:
from IO_Time in db.IO_Times
orderby SqlMethods.DateDiffMinute(IO_Time.TimeIn, IO_Time.TimeOut) descending
group IO_Time by IO_Time.IDNum into list
select new
{
ID = list.Key,
Time = list
});
This returns the correct IDs in the correct order, but the "list" contains everything in the database entry (which makes sense). I have also tried group by IDNum and Time, but then I get unique time entries and multiple IDs returned.I could do a foreach loop and manually sort it all out, but I would really rather not do that.

We have many different clients, and each client can have multiple user accounts.Right now, we have user settings set up on the ASP project, and a WinForms application can see these settings, depending on which user logs into the winforms application. They are specific to the user. I want to make them specific to the client, so users can be in "groups" by their client, and all users in the group would see/update the same settings.

I'm working on a portal, and I need to check users conection on the ldap.
And if users are members of a special group then it works.
I've exactly used this link to make it works : http://msdn.microsoft.com/en-us/library/ff649227.aspx (almost work)
My point is : my ldap path seems good, no error anymore, when I log with my username and password.But when I querry it, it returns null, but I'm sure my user is in the group :
// Bind to the native AdsObject to force authentication. Object obj = entry.NativeObject; DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(SAMAccountName=" + username + ")"; search.PropertiesToLoad.Add("cn"); SearchResult result = search.FindOne(); if(null == result) { return false; }
I'm a normal user, i test with my account. I'm a member of the group that I'm looking for.
