Hi,

We have upgraded to Intersoft Studio 2014. Our grid version is 8.0.7200.259. However, after upgrading we are unable to delete/Paste rows any row from the grid. Hitting the delete or pasting the rows gives us the following java script error -

Unhandled exception at line 1, column 3427 in http://localhost/[mysite]/ISRes.axd?G/WebGrid_Core2.js/807200259

0x800a138f - JavaScript runtime error: Unable to get property 'length' of undefined or null reference

I error is coming in the java script code at : c<a.Data.length 

Below is the complete java script code.

Please let us know what needs to be done to support these functionalites working in our application.

Thanks,
Ravinder
