    In my report, I want to change the value of a textbox based on the value of the row data. I can't really use an expression because I may need to do a additional data lookup (depending on the data). Instead, I use the detail_ItemDataBound method to process the row data and change the text. At the same time (using the same method) I also change the visibility of another text box.

    When I run the report, the visibility works fine, but the text is only changed on the row after the one being processed (the text for row n is displayed on row n+1). 

    Is detail_ItemdataBound the right place to do this processing? Would detail_ItemDataBinding be better?

    When do I use each one?

    Hello Dave Hayward,

    The most probable cause for that behavior is because you had set the new value to the textbox definition. Instead when you are in a DateBound event you have to use the Proccessing items.

    Check out the following help articles:
    Report Life Cycle
    Understanding Events

    I have attached a sample that demonstrates how to accomplish your task and demonstrates the behavior your have experienced using the textbox definition item.

    Kind regards,

    I realized my mistake soon after posting. I was finding the 'processing' data object for controlling the visibility of one control, but using the definition object for controlling the text. It was pilot error and not pilot ignorance.
