Asp.net - GridView AutoGenerateColumns And Sorting?
Aug 31, 2009
gridview sorting in VB.NET: I have a gridview with autogenerate columns = true
<asp:GridView ID="GridView1" FooterStyle-BackColor="Aquamarine"
AutoGenerateColumns="true" AllowSorting="true" OnSorting="Gridview1_Sorting"
AllowPaging="True" PageSize="12" OnRowCreated="GridView1_RowCreated"[code].....
I've declared the sort event handler (OnSorting="Gridview1_Sorting" ), and it works fine.However, then I change the column title (headers as they are in the dataset which I get from the database)
GridView1.HeaderRow.Cells(0).Text = "Document" ' "PROC_UID"
GridView1.HeaderRow.Cells(1).Text = "Process Step" ' "PROC_DOC_UID"
When I set the HeaderRow text, I can no longer click on the title to sort (it also is no longer underlined).How do I correct that?

setting the width of the gridview when i used the property AutoGenerateColumns to AutoGenerateColumns="true". And the gridview is databind in code behind. If i am using gridview1.columns(0).width it raise error.
And the GridView1.Columns.Count is always zero because the grid view is databind.
In .aspx: -
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true">
</asp:GridView>

I have done research on how to manually create sorting in a grid-view and none of it is thorough enough for me to follow. I need more of a step by step solution, like what event should my sorting code go in, how would i enable the headers to allow sorting. normally, i just have .net do this but for some reason this time it doesn't allow it, maybe because i am not using a datasource.that's my code that creates a datable and then binds to the gridview.
Function toptable()
Dim reader As SqlDataReader
cmd.Parameters.AddWithValue("@yeartoget", DropDownList1.SelectedValue)

I have a gridview that displays a calculated field, based on a db source field it populates with.
can i sort by it? i can't seem to figure out how to do it?
example:
my templatefield looks like this:
<asp:TemplateField HeaderText="Category" SortExpression="category" >
<ItemTemplate>
<asp:Label runat="server" Text='<%# BuildCategory(DataBinder.Eval(Container, "DataItem.category")) %>'
ID="lblPrice"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
where category is party of the datasource, but what gets displayed is a calculated value - which is different from the category.what can i put in the "SOrtExpression" to make it sort by the new value - taht gets displayed?

I re-wrote this to make it more readable. If you want to skip right to the chase, look at the ALL CAPS comments in the code blocks. All necessary code has been included for debugging. I've searched multiple forums (including ASP.NET), and the MSDN library and cannot fix this >.<

I have ASP gridview bound to an Entity Data source which works no problem, however when I try to programmatically change a header columns text, it appears to break the styling and will not allow sorting either, below is how I am trapping and changing the Header row column text.
Protected Sub gv1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv1.RowDataBound
If e.Row.RowType = DataControlRowType.Header Then
'retrieve the values from the userdeftable
e.Row.Cells(6).Text = App.Session.Company.UserDef3
End If
End Sub

I have a DataGridView and have the AutoGenerateColumns property set to false, but the when I build my project the columns are Auto Generated.
I can see the property set to false in the Designer.vb code for the Form.
I've had this problem before and I'm not sure how to fix it.

I have a WPF ObservableCollection which is bound to a ListBox and I have a Sort() method which when called will convert the ObservableCollection to a List(Of T), and undertakes a sort based on a date/time column within the collection.
The data is sorted, even when new items are added to the ObservableCollection, however the date/time isn't being correctly sorted. The data is sorting based on the date however it is very much random when it comes to the time portion. The following is an example of the outcomes I am experiencing:
[Code]...
Is there anything that I am doing incorrectly in this method that would cause the time portion not be included in the sort? Is there a better way of doing a sort?

I have a modal popup that contains a gridview. On the click of a button inside of a grid i reload the gridview with the data that depends on the id of the row clicked in the gridview. I would have like to reload the gridview onclientclick but I couldn't find a way to do that. Is it possible to reload a gridview client-side without the user even knowing the page partially loaded?

I have a the need for key value pair that I wish to sort so I decided to use a SortedList instead of a HashTable.I am adding the data in the order below to my SortedList which is the order I need it in
Key | Value
--------------------------------
1 "700-800" | List(Of Object)
2 "900-1000" | List(Of Object)
[code]....
The key is a string and the value is a List of objects. The key is representing a time slot that has been concatenated from two integer values and delimited by "-". "700" as a string was 0700 initially an integer.e.g.
Dim key As String = slotTimeStart.ToString() & "-" & slotTimeEnd.ToString()
But once these key value pairs are added to the SortedList they appear in the order
3 "1100-1200" | List(Of Object)
4 "1700-1800" | List(Of Object)
[code]....
Unfortunately I recieve the times slots as two integer values which cannot be changed.Is there any way to force a sort on a SortedList? or is this problem because of the way I am storing my key? Is there a better way to store it?

I have a VB.Net 2005 application in which I access a SQL Server DB to pull data into a Dataset. Within my app, this dataset is read sequentially. Then, a cross reference file is read against the dataset record. If there is a match (based on 2 fields from the dataset record), a field value from the cross reference file is used to replace a certain value in the dataset record. Once a dataset record has been read and processed...it is written to a new CSV file. This CSV file contains 5 columns.
I've been requested to now sort this new CSV file using 3 of the 5 columns as the "Sort Key". What would be the fastest way to do this?
I know one way would be to create a new dataset and insert the finished record into this new dataset in the order of the 3 fields (which I'm not sure how to setup).

I need to know if there is any simple way to sort an array in visual Basic.net. I have been trying for some time without any real reliable results or wierd results. Here is the code this is the sort routine which transfers a csv text file read earlier into an array.
Private Sub btnSort_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSort.Click
Dim i As Integer = 2 'inner loop
Dim j As Integer 'outer loop
Dim tempstore As String = String.Empty
ProgressSort.Minimum = 0
[Code]...
The data seems to be read into the array but the sorting takes a very long time and I am not sure if it is working or not. I have read from other forums that it is easier to sort the array read from csv before splitting it. This record I am trying to sort is 250 records long. I have no idea how long that should take. Not even sure if the algorithm I chose is correct.

I have two columns in a datagridview, one is a year and the other is a month. These two form a date, but unfortunately the structure in the database I'm forced to use is that of two integers. I need to sort the rows by date, using these two integers. I tried creating an unbound column with a date, but sorting this way seem quite difficult. So, I thought I could do a multicolum sorting by year first and then by month using two columns
