ADO.NET :: Filter Dataview Row With Top 10?

Jul 30, 2010

What I want is to filter the dataview so I get top 10.

I googled it and found out that I had first to sort the dataview. Then add a column (int) to datatable. This column I then made a AutoIncrement on......

This works fine - I can see in the codebehind that it adds a column to the datatable that I called AutoInc.

Then make a RowFilter on the dataview - here it goes "wrong" for me.....

When using the line

datVie.RowFiler = "AutoInc < 11";

and bind it to a gridview I don't get a error - but it also don't show me any rows in the gridview...... If I comment the line out - I get all the rows in the dataview..

Can anyone see in my below code what is wrong?

[Code]....

DataSource Controls :: Filter A DataView To Return All The Rows Whose Column X Starts With A Number

Jan 29, 2010

I'm trying to filter a DataView to return all the rows whose column x starts with a number: The following works in SQL Server:

select *
from dbo.Page
where Name like '[0-9]%'

However, when I try this:

dataView = new DataView( someDataTable, "Name LIKE '[0-9]%'", "Name ASC", DataViewRowState.CurrentRows);

I get "invalid parameter [0-9] with Operator Like" error message. What is the correct syntax to achieve my goal?

Active Directory/LDAP :: Nested Groups Filter/create A Filter Which Will Return All The Users Which Belong To One Of The "kuku"s Group?

Mar 9, 2010

In my organization we use nested groups. For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.

We may assume that no other group in the LDAP has "kuku" in the name.

I need to create a filter which will return all the users which belong to one of the "kuku"s group.

Obviously, using this filter will bring only the head kukus

(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=...rest of the group DN...))

How can I use wild card to fetch all users which belong to any kuku?

For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))

C# - Run Both Authorize Filter And Action Filter On Unauthenticated MVC Request

Mar 17, 2010

I have decorated my base controller with a couple of action filters. They work fine.

One of those filters sets up the request - does things like set the culture based on the domain, etc.

I also have a handful of actions that require authorization using the Authorize attribute.

My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page.

The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing.

I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization.

Add One DataView To Another In C#?

Jun 22, 2010

I need to add two DataViews together to have one Dataview that can then be bound to a Repeater.

I am plugging into someone else's API so I can't change the way the data is retreived at the SQL Level.

So essentially I want to do this:

DataView dView1 = getActiveModules();
DataView dView2 = getInactiveModules();
ModuleView = dView1 + dView2;
rptModules.DataSource = ModuleView.Tables[0];
rptModules.DataBind();

The two schemas for the views are identical just retrieving active and inactive modules.

Remove Record From A DataView?

Jan 18, 2011

I have a DataView which has been populated with a list of files from a database table. I want to iterate through the DataView to see if there are any files there of a particular type, and if so, do something with that record, and then remove it from the DataView.

I've coded this as follows, but there's something missing - I can iterate over an object and then remove an object from it, since that will affect the iterator.

DataView dv = new DataView();
dv = ds.Tables[3].DefaultView;
dlFiles.DataSource = dv;
dlFiles.DataBind();
for (int j = 0; j < dv.ToTable().Rows.Count; j++) {
if (dv.ToTable().Rows[j]["FilePath"].ToString().ToLower().Contains(".pdf")) {
//do something with this record and remove it from the dataview
}
}

As a note, dlFiles is a DataList used to display the the items in the DataView. The files removed are displayed differently, and so should not be referenced when iterating through the DataList.

ADO.NET :: Create Dataset From LINQ Query Of DataView?

Sep 27, 2010

Is there a straightforward way to create a dataset after querying a dataview? The query itself returns DataRowView objects, which I cannot get to work with CopyToDataTable().

The query looks like:

Dim dvQueryView As DataViewdvQueryView = (dataview object of large dataset)
detailTableQuery = From rowView
As DataRowView
In dvQueryView _
Order
By sSortOrder _
Select rowView _
Skip nQuerySkipRow _
Take nQueryCountRows

I only want a small selection of records from the large dataview and use those to create a smaller dataset. The large dataset stays in place while multiple views are created from it, and then from those views I want to create the smaller datasets.
