Hi,

To Reproduce the issue:

  1. A WebInput control for inputing Date Time (with Edit & display format and also mask exp.)
  2. Integrate the WebInput (from 1.) into WebGrid's columns
  3. Add A Button to Call WebGrid's Refresh All
  4. Run the Project
  5. Enter Edit mode for column with WebInput as input control
  6. Press the Refresh Button
  7. Try to Enter Edit mode for the same column again
  8. JavaScript Error
Message: Object required
Line: 7
Char: 24063
Code: 0
URI: http://localhost:4933/ISRes.axd?G/WebGrid_Edit.js/707200431

WebGrid's version: 7.0.7200.431

WebInput's version: 4.0.7200.29


Thanks and Regards,

Fung
