RadGrid : Selection Order

[Rahul]

Hi,

I am facing an issue with the selected items order . When we select multiple rows in the grid  using shift select the order of the selected values is not the same the order they are present in the grid. For example as we select row 1 and shift select row 10, we are expecting selection order as from row 1 to row 10, but what we are getting as row1, row 10, row 2-9. Please suggest me the possible changes to maintain the order.

Thanks,

Hello Rahul,

Generally, the SelectedItems collection of RadGrid returns the items in order of their selection time. I have prepared a sample RadGrid web site to demonstrate how you can sort their indices. Please run the attached application and let me know if it helps you.

MasterTable.get_selectedItems() is returning selected items in order in which they were selected but I want to ignore the selection order and get items selected in order in which they appear in the radgrid.

Please help!

Thanks,

Hello Ankush,

Thank you again for your patience.

You can achieve the requested functionality using the following approach:

function buttonClick() {
    var selectedItems = $find('<%= RadGrid1.ClientID %>').get_selectedItems();
    selectedItems.sort(SortByIndex);
}
function SortByIndex(a, b) {
    var aIndex = a.get_itemIndex();
    var bIndex = b.get_itemIndex();
    return ((aIndex < bIndex) ? -1 : ((aIndex > bIndex) ? 1 : 0));
}

Hope this helps. Please give it a try and let me know if it works for you.
