Hello Rajesh,

I am just checking the progress of this issue and was wondering if you managed to achieve your goal or if you need any further assistance on the matter.

Hello Rajesh,

Could you please send me an isolated sample project, where this is reproduced, so I could be able to investigate this further for you.

Looking forward for your reply.

We have a  Hierarchal XamGrid of 10k rows and 15 columns and we have functionalities to show/hide rows and columns. The issue is whenever some column is hidden, and if I click on the Templatecolumn which has ‘Textblock as ItemTemplate’ and ‘Textbox as EditorTemplate’ it raises the following Error.

Error Message:Value cannot be infinite or NaN.

Parameter name: System.Windows.CustomDependencyProperty

Hello Rajesh,

Thank you for your post. I have been looking into it, but since this is not a known issue and I cannot be completely sure what can cause this behavior, so could you please send an isolated sample project, where the issue is reproduced, so I can investigate it further for you.

Looking forward for your reply.
