Hello Bishwa,

The synchronization with the Header CheckBox is designed to affect all the rows within the RowsCollection without regards to whether the row is visible or filtered out. Therefore, when the checkbox is checked, the values for the filtered out rows are going to be set as well.

Internally, there have been discussion about possibility of providing a means to specify which types of rows are affected such as only the Filtered-In rows. If you would like to raise the customer demand for this functionality with our product manager, I would suggest entering a feature request.

In the meantime to achieve this functionality, you will have to handle the synchronization yourself, by setting the HeaderCheckBoxSynchronization to None, and modifying the value of the appropriate Cells in the AfterHeaderCheckStateChanged event handler. You can access all the Filtered-In rows, using the GetFilteredInNonGroupByRows() method off of the e.Rows parameter.

Please let me know if you need further assistance regarding this functionality.

Thanks,

Chris.

Unfortunately, this functionality has not be added into the UltraGrid yet. The feature request is still open and waiting for additional votes. I recommend voting on the feature yourself, as the more votes a feature gets, the higher the customer demand for the functionality is in the eyes of our product manager.

If you can't get the above solution to work, please let us know and we can help figure out why. For tracking purposes, it would be beneficial to create a new post (and reference this forum post) if you require further assistance. This will help guarantee timely responses.

Thanks,

Chris
