    I have a radgrid with a sql datasource hooked to it. I set the datakeynames = the identifier value of the sql datasource. I have multiselect set on the grid but when I select multiple columns the selectedvalues only shows the last one selected. I need all of the keys selected.

    Hi,

    Please take a look into this help documentation which describe how to get the DataKeyValue from selected row.

    Thanks,
    Princy.

    Should I then not use the SelectedValues property at all?   My SelectedItems list is correct and I can certainly loop through it to make my own list of selected key values but it seems this should already be done in the SelectedValues property which only ever seems to return one value?

    Nevermind, I understand now.  The SelectedValues is not a field to contain key values from multiple rows that were selected, it is the plural of SelectedValue if one row is selected but multiple key fields are defined.

    Hi Charles,

    Yes, you are correct. You can traverse the SelectedItems collection of the grid to access the details of the selected items:
    http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/functionality/selecting/how-to/retrieving-primary-key-field-values-for-selected-items
    https://admin.telerik.com/docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-raw-field-data-and-key-values​

    Please note that only the visible records on the current page are loaded at a time, therefore, to get all the items through all pages, you will need to temporarily disable paging. You can examine the sample provided in the last post for an actual implementation:
    http://www.telerik.com/support/code-library/get-selected-items-through-all-pages#1eTU8nr-GUG8zfGgOGbIcA

    Hope this helps.
