how to sort a bindingsource basing on a column that has alphanumeric values
View 11 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?

Is it possible, out of the box, to sort a .NET DataGridView column using only the keyboard?I understand there is a SelectionMode property, but changing this merely allows me to select, using Shift+Space, an entire row or column, but this doesn't have the same effect as clicking the header with the mouse and causing a sort.The reason I ask is because I am working on accessibility issues and would like to avoid relying on the mouse.

View 7 RepliesI've got a DataGridView that has a DataTable as it's Datasource. Whenever I sort a column and then edit a cell, after editing the column, the column autosorts so the recently edited cell is no longer in the viewable area. Is there any way to prevent this auto sort from happening and only sort when I click on the columns?
View 2 RepliesI want to sort the binding source column (Product Code) which formatted like (AA-AAA AAA AAAA)
but i do not want straight sort on product code column, i want the sort as :
substring of 1,2 + 8,3 + 3,3 and then the rest of the column.
I know i can do it in the table direct using the OrderBy and the substring function, but the problem is that sort is not static it is dynamic according to different status means it change the substring order.
I need to sort the rows in a bindingsource. When I sort by a field name, ASC, it works correctly, but when I sort in DESC mode, instead of being the opposite of ASC, it sorts the rows whose fields have the same value in ASC order. For example:
I've got a column with the values A, B, P, P, P and P
ASC: A B P(1) P(2) P(3) P(4)
DESC (as i want it to be): P(4) P(3) P(2) P(1) B A
DESC (as it sorts):P(1) P(2) P(3) P(4) B A
Is there any property in bindingsource which I can use to change this?

So basically, 10 rows and 3 columns and say I want to sort them by the values in the 3rd column.
Each row is essentially a record of data and must be kept together.
Now I know that you can't use the array.sort method but would I have to use a bubble sort or something for this?
What's a good way to manipulate the records while still keeping each row linked together somehow.
