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?

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 1 RepliesSimple question, I have an application and dependant on whether you are in the administration system or on the public website I want to show different results. Example: in the database for a news story in the administration I may set the column value 'showonsite' to false. So I would like this to show in the administration panel only and not on the live site.
My question is, because I require the same information just with the only one column change, live site to only show true values and administration to show both. What is the most effective way of achieving this without copy paste of code?
