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'm having my program sort an excel sheet by a few columns. However, it is only sorting by the first column not the rest that I specify.ere is my sort code below:

deal with ever changing SQL queries based on various conditions? i am using Cmd.BindByName = True so it doesn't need to be in an ordered way when adding parameters. Just that this is the hectic way of doing the update SQL ..or even worse insert SQL/I favor doing parameters instead of using stored procedure bcoz i find it faster by using parameters .
SQLStr.Append("Update Table set col1 = :time ")
Cmd.Parameters.Add("time" , OracleDbType.Varchar2)
Cmd.Parameters("time").value = "xxx"

I'm trying to sort multple colums in the DataGridView which is unbound. I would prefer to sort by using a DataTable/DataView but for some reason another developer in my team experienced other problems relating to sorting so he abandoned using the DataTable to fill the grid :(
Here is the senario: I want the user to be able to choose which columns they want sort on. The way I envisaged was to show a form with a listbox, a grid and 3 buttons (Add to sort, Remove from sort and Apply Sort).
The list box would be populated from the parent form grid column headings.
The grid will show the columns and sort direction.
Button 1 would add the selected item of the list box to the grid.
Button 2 would remove from the grid the selected row.
Button 3 would Apply the Sort in the order of the grid and the columns SortDirection.
Now I looked at How to: Customize Sorting in the Windows Forms DataGridView Control using the IComparer [URL]
how I can use the IComparer to sort on multiple columns that a user has specified or another way to sort on multiple columns using unbound data.

View 5 RepliesI have an unbound datagridview that I populate with data. When the user clicks on the column head the datagridview is sorted - which is fine for alphabetic fields but I have a column that contains numeric fields and goes from -100 to +100. This is sorted incorrectly by the number (all the 1s first then all the 2s and so on, ignoring the minus sign). How do I get it to sort my column numerically?
View 9 RepliesI have a datagridview with a column called "Total Price". This is set to a string value type because I need to always show 2 decimals. For example:
4,3
must be in the datagridviewcolumn:
4,30
So I use string.format for this. However, now I have a problem with sorting because the column is a string value type and numbers get sorted like this:
50
4000
40
300
30
20
10000

View 1 RepliesI have a datagridview which is bounded to a table m_table constructed in my code. A column named price has decimal type.
DGV.DataSource = m_table
DGV.Columns(columnPrice).ValueType = System.Type.GetType("System.Decimal")
All prices are in decimal. But I found that when clicking the column header of DGV, the price column is sorted like a string. For example:
9.0, 13.5, 8->13.5, 8, 9.0
But I want sort numerically, that is 8,9.0,13.5
I wonder why decimal type cannot be sorted numerically. How to achieve this?

I've got a datatable with a DateTime field that I want to sort using a DataView. I only need the Time part of the column though, and not the date. I can't get it to show just the time and not the date as long as its a DateTime column. I know I could convert it to a string to get the time, but then it wont sort correctly.
View 1 RepliesI have this code that use to sort a datatable.
Dim sortingIndex As Integer = orderby
Dim DataTableNew As DataTable = New DataTable
DataTableNew = dt.Clone
Dim query = (From c In dt.AsEnumerable Order By c.Field(Of String)(sortingIndex) Ascending)
query.CopyToDataTable(DataTableNew, LoadOption.OverwriteChanges)
My problem is that with this method I always need (Of String) for it to work, so the date columns are also managed as Strings witch is the problem. Is there a way to use the correct type so the sorting is based on the type of the column?
I have a dataview object that is being populated by database fields - so I can sort on these partulular columns by specifying the actual column names without any difficulty. However, I have been asked to add a few more columns to the dataview, and these columns will be calculated columns, not directly derived from an underlying database column.The users want to be able to sort on these new columns as well - even though there is no actual column name I can use to sort.
I have not been able to see where I can sort a dataview based on the actual column integer value used when the user clicks the appropriate heading to sort.

I have a DataTable in a DataGridView, one of the columns has data that I want sorted. I can click on the column header to sort it and it's fine. The problem is that I don't want that column sorted automatically when some of the data changes in it. I want it sorted only when I click on the header.

I am trying to fill a temporary table with one column( a code) with the unique results of three queries of their respective table adapters.I can't figure out how to do it from here.The database is Access 2007 and I have activated the appropriate dataset on the form from which this code executes. The table adapters are part of that dataset.I could try to use the recordset approach, but that means making another connection to the same database.Is that a preferable approach?My purpose in doing this is to build a VB process like the one that works in a VBA Module of this Accessdatabase, partly to help me learn VB2008 and partly to overcome the necessity to keep updating queries used by the module.Code below

I have a Datagridview, It will have pairs of lines:
first line: requested customer
second line: assigned quantity for that item for that customer
Something like:
CUSTOMER-ITEM-VARIATION1-VARIATION2-VARIATION3-VARIATION4
Cust001....-120.-......10........-.........0.......-........8........-.........1
Cust001....-120.-........0........-.........0.......-........0........-.........0
Cust002....-120.-......15........-.........7.......-........2........-.........0
Cust002....-120.-........6........-.........0.......-........1........-.........0
The second line will have numbers if other table has information about that customer reservations, or will be in 0 if not.I can load the first line of each pair, with the data of the "requested" items loading a datagrid with a datatable.
