Which icon is displayed in datagridview?

Okay, so I have an application which displays various icons depending on the state of the entries in a .NET "DataGridView". I need to verify that the correct icons are displayed.   How would one go...

    OK.

     

    I think I have a viable property (Field) you can use.

     

    The grid is zero indexed (you show Row 1, Row 2, Row 3 etc in your sample .... they are actually Row 0, Row 1, Row 2) which may confuse some.

     

    But it looks like the - ["nativeImage"] - value (which is a "Field" rather than a "Property") contains a number directly linked to the image displayed.

     

    Full ref to it being:

     

    NameMapping["Sys"]["Process"]("IconDatagrid")["WinFormsObject"]("FormMain")["WinFormsObject"]("dataGridViewExample")["wValue"](<ROW NUMBER>, "Pick this")["nativeImage"]

     

    Which returns:

     

    75768992 row 0
    75763416 row 1
    75768992 row 2
    75768992 row 3
    75763416 row 4
    75763416 row 5
    75768992 row 6

    and so on ....

     

    ... which ties in perfectly with how the images vary.

     

    So 75768992 is your white image. And 75763416 is your red one.

     

    A lookup table for them would seem sensible to make things a little more meaningful.

Wow, that works!

I just hope those odd numbers don't change when we recompile the application.

 

Thanks a lot.

    Yeah. Thats the unknown.

     

    You'd like to think not though!

     

    If you have access to the devs, they might have some idea how the icon and that number are tied together.

     

    HTH. :smileyhappy:
