I am not sure why I am getting this above Extra Row without Header. Its intermittent, sometime it show some time it’s not when I change the tab index.   And even when I click on it throws Exception.

please find the attached Zip file for MVVM implementation. and Snap shot of error.

Please revert as soon as possible.

Thanks

    Hello Anant, 

    I have been looking into your enquiry and the attached code, however by looking into it I cannot seem to figure out what might be the cause of this issue. Also I tried making a sample project out of this, however the code seems to incomplete with what seem to be missing reference. As this extra row is not something common I have seen before and I cannot seem to replicate it on my side, please send me an isolated working project, so I can continue investigating it for you. 

    Looking forward to hearing from you.
