I am creating a RadGrid and initially assigning the sortExpression to use the data column, "Plcmt Date" as its FieldName:

 

<SortExpressions>

 

 

<telerik:GridSortExpression FieldName="Plcmt Date" SortOrder="Ascending" />

 

 

</SortExpressions>

 

the column seems to be set up correctly:
 

 

 

<telerik:GridBoundColumn HeaderText="Plcmt Date" UniqueName="PlacementDate" HeaderTooltip=""

 

 

SortDescImageUrl="../RadControls/Grid/Skins/Default/SortDesc.gif" SortAscImageUrl="../RadControls/Grid/Skins/Default/SortAsc.gif"

 

 

DataField="Plcmt Date" SortExpression="Plcmt Date" AllowSorting="true" FooterText="Grand Total">

 

 

 



but I am getting this error:

Error serializing value 'Plcmt Date ASC' of type 'Telerik.Web.UI.GridSortExpression.'

Is it because there is a space in the column name or something?   I've looked all over the site and don't see anything about restrictions on column names that can be used for sorting.

Never mind.   the error was because I was trying to save the Sort Expression in ViewState and you can't do that without making it serializable.
