Expression editor of LINQDataSource RRS feed

  • Question

  • User-1631673752 posted


    I'm trying to find attribute usage of expression editor, what I'm trying to do is a developing composite control which includes LINQDataSource control properties like "Select", "ContextTypeName",

    When you click "Select" property of LINQDataSource control VS pops up an expression editor with parameter editor, i couldn't able to find attribute lists/usage of this property so i can't utilize this editor.

    I'll appriciate if someone help for this editor attribute lists/usage, I've searched system.web.ui.design.webcontrols namespace (also MSDN) but couldn't find anything.

    Best Regards

    The LinqDataSource designer has a editor that allows you to edit the expressions and associated parameters from the property grid.  The EditorAttribute that specifies this can be found on the LinqDataSourceDesigner's Where, OrderBy, GroupBy and Select properties.  The designer is overriding the ControlDesigner.PreFilterProperties method in order to control what properties are seen in the property grid.

     Is this what you were looking for?
