How to access instance self?

[W]

For example:

Item is string "abcd", lambda is Item.Any(param=>param == 'd'), how to write the expression string?

Hello,

If you want to modify the expression string of RadExpressionEditor, you can use its ExpressionText property. You can find more detailed information on the matter in RadExpressionEditor article. You can also take a look at our online demo where you can see how to use it.

I hope this helps.

If RadExpressionEditor.Item = "abcd",how write the expressionText(RadExpressionEditorExtensions.TryParse's param) to get the Expression like "Item.Any(param=>param == 'd')" by RadExpressionEditorExtensions.TryParse.

Hello,

Generally, the ExpressionEditor is designed to work in a scenario where the item is a complex type and would not work in the specific requirement you have to filter a List of strings. Can you confirm if this is the setup at your end? Can you please provide more information on the functionality you aim for so we can suggest a workaround? Are you using the ExpressionEditor in a combination with RadGridView? 

The best case scenario would be to raise a ticket and provide a sample project which we can familiarize with and advise you more accurately.
