View 1 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?

I have a listview set up in Details View and I run a ascending/descending sort routine on the appropriate column when the user clicks one of the column headers.However, when I switch companies and reload the listview with new information, for some reason the event fires and I get an indexoutofrange exception as I believe that the information has not yet loaded when this fires.The e.Column property is set to that of the previous column which I clicked even though I have clicked nothing.

View 2 RepliesI 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

I support a .Net 2.0 Windows application that has a custom listview control to allow for greater flexibility. I am not allowed to bring this to a newer version of the gramework until next year. We are moving from XP to Windows 7, and we have identified an issue with how the column sort image (up/down arrow) is drawn to the listview. Currently in XP, the image is drawn to the right of the column's text. However, in Windows 7, I am getting Access Violation Exceptions. Now, I know that the error is with the improper handling of memory using the unmanaged code as shown below. I am looking for a method to mimic what we have below in a safe manner using managed code.

The problem is that I can only find examples of sorting in alphabetic order (with IComparer). Does anybody have an example?
I found these files code on CodeGuru and tried to add the code to a .net project but i got to many errors to debug.
I am not sure but i think it is VB6 perhaps.

I created a DataGrid by dropping a DataSource on my Form. When I run it in debug, it works great.

How to sort items in ListView by column bound to an Observable Collection ?I've looked all over the place and I can't find anything easy enough or simple on this.
View 2 RepliesHere's the issue in a nutshell (I can elaborate if you feel it's needed). In a DataGridView I want to capture the value of the row's key column so that when the user clicks on a column header to sort the data, I can reposition to the row that was selected prior to the click. The problem is that the sorting itself, once it's done, fires the same events (RowEnter for example) that I used to determine my key value, so it sets my variable to a new value and now
View 7 RepliesUsing VS 2005 I've created a project with some form on it. Each of the forms are fairly similar in structure and I have copied the contents of one form to another form etc. I have code the loads the data into the ListView on each form and that works fine but when I put a Click event on the ListView, it doesn't fire. I created a new project to do some testing and put some items in the ListView and the Click Event fires when I expect it. What am I overlooking? The code for the Form is included below: it loads the data fine and I can select a line in the ListView but as previously stated, the Click event just won't fire!

I have an explorer-like form with a TreeView and a ListView. I have finally figured out how to populate the the ListView based on the selected node, but when I am debugging, I click on a node, and the ListView doesn't change. I have to single click twice on the node for it to work. What could be my issue? I have included the code from my sub below.
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Dim newSelected As TreeNode = e.Node
ListView1.Items.Clear()
Dim subItems() As ListViewItem.ListViewSubItem

I have a datagridview on my windows form bound to field "STATUS" in SQL database with the default value of 0.What i want to acheive is that for each row in the datagridview, if user clicks the checkbox column only it should display a message " LOCK THE ROW?". If user chooses yes then the entire row should become readonly including the checkbox check "Greyed out" or disabled for that particular row and update value to 1 in the database field.I created checkbox by:
'on form Load_Event
Dim colCheckbox As New DataGridViewCheckBoxColumn()
colCheckbox.AutoSizeMode =DataGridViewAutoSizeColumnMode.ColumnHeader

Does anyone know why a ListViews dragover event does not fire when dragging over a listview column header or an empty row?I'm trying to highlight the row a user is dragging over. Everything works with the exception that when I drag over the column header or an empty row the previous row stays highlighted since the dragover event doesnt fire. Is there another event that I should be looking at? I've checked the hover over and it doesnt fire either.
View 1 RepliesI am using Visual Studio 2008 and VB.NET. I've got a listview control on my form and I've added columns using the windows forms designer. As you know, if you double-click on the sizer or divider or whatever you want to call it between two columns, the column on the left will autosize (unless you disable that). How can I catch this specific event? The ColumnWidthChanged event and the DoubleClick event are likely candidates, but in the ColumnWidthChanged event, there's no way I can see to determine if it was an autosize. Similarly, there's no simple way to catch what was clicked exactly with the DoubleClick event. how I can catch this specific event type?

Currently my ListView sorts items by image.index. So 0 is at the top, then 1, 2 and so on. Think of it as an IRC chat room nick list. Ops at top then the rest are sorted alphabetically

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...

I have 4 items in a ListBox and each item does a specific thing when it gets clicked on.But I also want the double click event to do the same thing as the click event.I can copy and paste all code from click event into double click event, but then you have lots of code crowding the code page doing the same thing. So what to do about this?
