I am currently trying to sort on a GridView after it has been populated with records from a SQL Server Express database. I click on a column to sort it and I get the following error: "DataTable must be set prior to using DataView." The entirety of my code is as follows: <script runat="server" >

View 7 RepliesI have a column in my GridView which pulls in an individual's name. Unfortunately, the name is contained in one column in the database - both first and last. I'd like to sort on the last name, not the first...is there a way for me to tell the GridView to sort based on a substring? [code]...
View 1 RepliesI am binding a data set to a GridView in VB .net. I have some custom sorting setup, and want to display an icon next to the header if one of my 3 options is selected.
I've read a lot of methods in doing this, and I see Gridviews even have a ASC and DESC header style I can associate with the view. I have 2 problems with this, though:I am sorting a List with linq on Sort Trigger, then binding it to the datagrid.
The reason I do it this way, is I want to maintain multiple sort levels, ordering by 3 columns rather than 1.
Edit for clarity Specifically what I want to do is loop through the value of a GridView's Header text, see if it matches what I have saved in viewstate, and if so add an image for that header in particular. Something essentially like below, however headerRow.Cells(y).Text is always returning "", even when the header has text:
Sub gvPatronData_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
Dim savedSortDirection(), savedSortColumn() As String
Dim headerRow As GridViewRow = gvPatronData.HeaderRow

I have coded my program so that when a user clicks on a column, the data is sorted in ascending/descending order.When I go to click on a column header, however, nothing actually happens.I dont get an error or anything.Here is the code that I am using to sort the records in the GridView:
Property GridViewSortDirection() As SortDirection
Get
If IsNothing(ViewState.Item("GridViewSortDirection")) Then
Return SortDirection.Descending

I have a LINQ Query:
[Code]...
This works great and sorts on L_Name. But I am trying to allow the user to sort the gridview themselves so I am passing in the SortExpression as a string. But I don't know how to incorperate the SortExpression into the LINQ Query. I tried Order By c. & SortExpression but that did not work.
I got a gridview which auto generates columns. One of the columns is a date field.Somehow, i cant sort the date field. It's being interpreted as a string.The data comes out a database. The datatype there is set on datetime.his is the code in the aspx file:
<asp:BoundField DataField="date" HeaderText="date" SortExpression="date" DataFormatString="{0:dd/MM/yyyy}" HtmlEncode="false"/>

i have a GridView bound to a DataView. Some columns in the DataView's table are foreignkeys to related tables(f.e. Customer). I want to enable sorting for these columns too, but all i can do is sorting the foreignkey(fiCustomer) and not the CustomerName.
I have tried this without success(" Cannot find column ERP_Customer.CustomerName "):
<asp:TemplateField HeaderText="Customer" SortExpression="ERP_Customer.CustomerName" >
A tried also the DataViewManager, but i've a problem to detect the table to sort:
Dim daCharge As New ERPModel.dsERPTableAdapters.ERP_ChargeTableAdapter
daCharge.Fill(dsERP.ERP_Charge)
Dim viewManager As New DataViewManager(Me.dsERP)

I am trying to program my page in vb.net and asp.net so that when a user clicks on a column heading of a gridview, the data is sorted either in ascending or descending order. note that my data is coming from an SQL Server Express database. So far, I have done it so that the gridview can be sorted:

I'm trying to sort records in the gridview right after a radio button is selected. My approach is with the dataview, but because the dataset variable doesn't survive a round trip to the server, I don't know how to make this happen.[code]
View 1 RepliesI have a gridview in asp.net/vb and it is bound to a list - so there's no standard sorting available. I've found this jQuery plugin for sorting tables: [URL]. The plugin requires <thead> and <tbody>. The problem is, that my gridview only renders the <tbody>.
I've already tried
DataList.UseAccessibleHeader = True
DataList.HeaderRow.TableSection = TableRowSection.TableHeader
But this changes nothing.
My gridview markup:
<asp:GridView runat="server" CssClass="grid" ID="DataList" AutoGenerateColumns="False" AllowSorting="True" ClientIDMode ="Static">
<Columns>
<asp:BoundField HeaderText="SomeHeaderText" DataField="SomeDataField" />
<asp:BoundField HeaderText="SomeHeaderText" DataField="SomeDataField" DataFormatString="{0:dd.MM.yyyy}" />

View 1 RepliesI have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview. I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows). If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that.

I don't understand what's going on here I published my project, and when I create new records and save them, everything gets saved and shows up each time I run the program.I open the database in SQL Server and none of the tables have the new data, but it still shows up when I run the program each time.
View 15 RepliesWhen I do Data Importing (CSV to DataGrid), everything runs normal except one problem.
CASE 1: If the Original CSV Data is: "ABC" It will appear as like ""ABC""
CASE 2: If the Original CSV Data is: O"K" It will appear as like O""K""
It will create extra quotes after importing into the datagrid. Does it related to Split() function?

On the form I have a dataset, bindingsoure, and tableadaptor (all created by the IDE in response to binding the text property of the label) To fill the datatable, the IDE created this: Me.ClientsTableAdapter.Fill(Me.MyDataSet.Clients) Works fine. The bound field is a phone number, stored in the db as a 10 digit numeric string I need to format this with the standard ()-, and I have a function that will do just that. How can I apply the formatting so the phone number appears in the label properly?

I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]

What I'm trying to figure our is how to get the dataset in the same order that ths would be viewed in a treeview, which in this case is the levels at the appropriate levels for the nodes and then the children at the appropriate levels sorted by the name. It would be like binding this to a treeview and then simply working your way down the nodes to get the right order.
