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 3 Repliesi am curious and also would like to know how to duplicate this user interface feature in Windows 7. I am aware that if you attempt to sort a column in Windows XP, there is no up/down arrow in the column.
Please have a look at [URL]...It shows part of the task manager process list, and image name column is sorted in descending order.What i am trying to find out is how is the arrow pointing downwards (representing descending) is created.
Am i able to reproduce this "arrow pointing downwards" in VS 2005?

I have a program that uses a richTextBox to append and save file locations. Each line in RichTextBox1.Lines is added to a listbox for the user to see the files. The format of the richtextbox output is shown below:
C:UsersJordanDownloadsfile.ext
C:UsersJordanDownloadsfile2.ext
C:UsersJordanDownloadsfile3.ext
I have a button on the form which can remove an individual file from the ListBox with the code shown below. The problem I am having though is that the RichTextBox text is ending up formating like shown below. If I remove the C:UsersJordanDownloadsfile.ext for example, the RichTextBox text will show as:
<vbCrlf>
C:UsersJordanDownloadsfile2.ext
C:UsersJordanDownloadsfile3.ext

View 2 RepliesI have a datagridview with a datasource from a MySQL query. Works fine. However, I want to add an extra column and generate some data into the cells. This works fine too and shows up as intended. However, I cannot sort on that extra column and the contents of the cells in the column are cleared out if I sort on the other colums. I realize this is all because of the original datasource, but Im hoping there is a way to "connect" the extra column in somehow?
Grid_SearcherResults.DataSource = dbconnection.bSource
Grid_SearcherResults.Columns.Add("Location", "Location")
'Then some code to set the value of the cells in the new column.. etc

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?
