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..
In securing actions/controllers, do I have to create a custom filter or use MVC built-in filter?
To use the built-in attribute Authorize() on an action/controller or create a separate class that inherits the ActionFilterAttribute which has a method (OnActionExecuting) to override and do the authentication there?
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.*))
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.

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.
How to select top n rows from a datatable/dataview in asp.net.currently I am using the following code by passing the table and number of rows to get the records but is there a better way.
public DataTable SelectTopDataRow(DataTable dt, int count)
{ DataTable dtn = dt.Clone(); for (int i = 0; i < count; i++) { dtn.ImportRow(dt.Rows[i]); } return dtn; }
I want to check that the row index I specify is below the row count so it doesn't throw the error
Index 2 is either negative or above rows count.
how would I achieve this with my code?
Using connection As New SqlConnection(connStr) Dim command As New SqlCommand command.Connection = connection connection.Open() Dim a As New SqlDataAdapter("SELECT top(3) name, (SELECT TOP (1) ImageId FROM Images WHERE(productid = products.Id)) AS imageId FROM Products WHERE beginnerdiscount = '1' ORDER BY Dateadded", connection) Dim s As New DataSet()......
I have a DataView object with productID and productName,i get all items from Products Table and store them in Cache.I want to get items that user bought in order he bought them without using another query or joining tables. ie.
Products DataView 1. Foo 2. Foo2 3. Foo3
Filtering to ProductsBoughtByUser using RowFilter (productID in (1,3)) UserProducts DataView 1.Foo 3.Foo3
Now user first bought Foo3, how do i reorder items based on correct ( chronological ) Array. ie 3 1
I am using VB. ASPNET2008 to develope Web Application. I am not sure whether to insert control DATAGRID or DATAVIEW. Also, what Reference Library am I supposed to use in order to use the Control.
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.
