 |
|
At one point in my code I clear the data from the tree by setting the DataSource to NULL.
At another point, I check whether the user has selected any items in the tree by checking for SelectedItems->Count > 0. I find that SelectedItems->Count = 1, after I set the DataSource to NULL. If I look at the SelectedItems property in the debugger, Count is 1 but all values in SelectedItems are <undefined value>. SelectedRows.Count is also 1.
Is there some other method I should be using to clear the tree, or to check whether any rows are selected? |

You're right, it does - I had forgotten about that one.
I am using version 2.7.0 - I am still on VS2003, and can't really upgrade at this point.
I ended up working around the previous problem by adding an extra check in the code. |
