VS 2008 Clicking Column Header To Sort?
Jul 9, 2011
I have a VB 2008 connected to my localhost SQL using DataGridview, BindingSource and DataTable. All works fine, i can add, edit and delete the row and the SQL database is also affected.
However, there is one thing that bugs me, that is sorting.
Problem My table in this database is still quite empty, it only has 6 rows
However, if I spam-click the column header, the sorting seems taking some time to sort, so that, the sorting result does not follow my mouse spam-clickings
Note: Spam Click = Clicking the mouse button in high frequency, something like click click click click click click click click click, etc
I then make a debug button to check this
Variables:
Dim DebugInt As Integer = 0
Dim bs As New BindingSource

A datagridview is sorting numerical values (when clicking the datagridview column header text) in the wrong order based on the initial digit:

It 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

I have a listview control that I have a multitude of files displayed, in addition there are 6 columns in the listview that shows information about the file in question.
I have gotten this far, but my question is this: how do I allow the user to sort the listview by clicking on the column headers. Like one can do in list view in a Windows window?

I�m using VB.Net 2008 application program.I�m using DataGridView. I have a Print option where i need to print the DataGridView. I�m using this code for Printing and for Print Preview.
Code:
Dim MyDataGridViewPrinter As DataGridViewPrinter
Private Function SetupThePrinting() As Boolean
Dim MyPrintDialog As PrintDialog = New PrintDialog()
[code]....
Attached the class i'm using for print.I have 10 fields showing in datagridview. As the last 5 columns header is long, the datagridview is not fitting inside 1 page (not showing all 10 fields in one single page). But is there a way i can "Text Wrap" the top header column and lock in the width, then it should print across one page perfectly.If you know how i can "Text Wrap" the top header column and lock in the width to print across one page?

I 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 working on my own listview control, and I was wondering if it was possible to get it to not draw the text for the listviewitem when the listview is in report mode? What I have been doing is putting all of my information in the tag and leaving the text property blank so it doesn't paint. Andis there a way to paint the background of the column headers? Because It only allows me to paint the actual column header? Here is what im talking about for the background of the column headers.

I have a windows application with many forms. We use the DataGridView control on most of the forms, but on a new form that I designed I have four DataGridViews. All of the DataGridViews on this form do not dipaly the Column Header Text when the form is displayed when running in the IDE. I do not receive any errors or messages. The other DataGridVeiws on other forms display their column header text just fine. I am at a loss as to why this is happining on this form.
UPDATE: If I add the desired text to the column.HeaderText property at the end of the form load event it displays the column header text. For example AssignedAmountColumn.HeaderText = "Amount" it displays Amount in the column when run from the IDE.... However it dosn't display when the property is set though the Columns property at design time.

Looking at deleting columns in excel and have found several threads that show how to delete an entire column which I have tested and done successfully. These columns were all identified by "A", "B", "C" and so on...
I was wondering if it was possible to do the same thing using the column headers. When deleting the columns in excel, one has to keep in mind that columns deleted from the left will shift the entire sheet to the left and if one is not careful, the next column[code]...
Let's say a user wants to delete the 'Middle' column (assume as column B in excel) and then delete the 'Suffix' column (assums as column D in excel). If they don't know to work from right to left when deleting columns, they would write code that would delete Column B and then repeat that code for Column D. However, once column B is deleted, all columns will shift left, which will result in the 'Phone' column (formerly column E now column D) being deleted instead of the 'Suffix' column (formerly column D now column C).
If there was a way to delete the columns by their headers (i.e. Middle, Suffix...) this would eliminate the problem; to me it seems a bit more intuitive as well.

I have a DGV that is populated at run time from a db query. One of the columns is sorted ascending and the column header for this column displays the little "up arrow" thing to signify it is sorted. I do not want the user to be able to click this (or any other column header) in this datagridview.
How can I maintain the column's visibility but disable the click function?

I currently have a DevExpress GridControl where one of the columns have a GridLookUpEdit assigned under ColumnEdit. Yet when I run there is a column name (the display member) that shows up.I know with a LookUpEdit you can set the column headers to invisible with lookupedit.Properties.ShowHeader = False but I have no clue how to make it invisible for the GridLookUpEdit.
