Get values from cell (order)

[wnl]

Hi, I want to get values from grid from two columns.
I have a function for getting values from one column:

string tmp = String.Empty;
            if (rg.SelectedItems.Count > 0)
            {
                int i = 0;
                foreach (GridDataItem DataItem in RadGrid.SelectedItems)
                {
                    TableCell cell = DataItem[columnName];
                    if (cell.Text.Length > 0 && cell.Text != " ")
                    {
                        tmp = String.Format("{0}{1}{2}", tmp, i > 0 ? ";" : "", cell.Text);
                    }
                    i++;
                }
            }
            return tmp;

For example my grid contains data:
Column1  Column2 Column3
1    2 3
4    5 6
7    8 9
If I execute code 2 times (for Column1 and Column3, could I be sure thay values will be:
"1;7" and "3;9" (right order, from top to bottom in those 2 cases)?
 Or the order could be random for example: "1;7" and "9, 3"?

Hi Wnl,

Items are added to the SelectedItems collection in the exact order they are selected. So if the selected items remains the same, then yes you could be sure what is the order. But if you are using AJAX and in case every checkbox makes post-back, then it is possible if the user checks them too fast, some of the selected items are not added to the collection. To prevent this you should wrap the grid in panel.
