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 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 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 have total column in gridview in which data should like

936(69)
1649(132)

973(101)
1535(165)

When I sort this column I got result like :

790(126)
718(71)

I have a filtered gridview in an updatepanel.I want to allow to sort filtered data.How can this be done?When I click to sort a column it reloads the entire gridview.
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 have a column with dates on it and I'm trying to sort it according to that.[code]I tried to use this but it only sorts by the first two digits, dd, and not with the full date.
View 7 RepliesFirst off a great piece of code [URL] you saved me soooo much time. I am a somewhat newbee to VB2010 and was wondering how would i go about setting lets say setting column(4) to a date format so that i can get it to sort in the correct order.
View 8 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick

VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

I 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 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" >

I have a LINQ Query:

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 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">
