| Hi,
| What's error you got if you change the Linq query to one with different
| colums after postback?
|
| Why you need reset the LinqDatasource? It sounds you had better build a
| Datasource object by Linq dynamically, don't you?
|
|

| the-linq-dynamic-query-library.aspx
|
| Does that make sense?

| | I have a grid with a LinqDataSource.
| | In the linqdatasource.selecting event I
| | use e.Result =( a linq query).
| | I do this because I have one aspx page where I return a query with
| different
| | columns based on what the user wants to see. The grid has autocolumns
| | selected. Thus I change the columns and query at runtime.
| |
| | The problem I have is if I enable sorting, I get an exception if I
change
| | the linq query to one with different columns after a postback.
| |
| | Essentially in the LinqDataSource1_Selecting
| LinqDataSourceSelectEventArgs e
| | e.Arguments.sort.expression has a value that contains a column that is
| not
| | in the new linq query and it barfs.
| |
| | Is there a way to clear this value on a postback.
| | I tried reseting the Grids datasource and nulling the LinqDataSource,
but
| | nothing worked.
