Hello,
We researched the issue and here are our results.
The "Select all" check box works only for visible rows so its disabling when there is no any visible row is expected. The "Select all" check box mode is defined by the GridViewCommandColumn.SelectAllCheckboxMode property. For example, we have three groups on the page and SelectAllCheckboxMode is set to "Page". If the second group is expanded and we check the "Select all" check box, only visible rows are checked. Then, we expand the first group, the "Select all" check box state changes to intermediate, since the first group rows were not checked. After that, if we collapse the first group, the "Select all" check box is checked again because all visible rows are checked. Analyzing invisible rows' state can confuse end-users in this case so this behavior is required for better understanding of the state of rows. I hope this information helps.
Hello,
the functionality does not work as you described. In attached video you can see malfunctions of this functionality.
If I expand only one group and check "Select all" checkbox it checks all records in grid (invisible rows included). At the end of the video I use "Delete function" to delete all selected rows and all rows (invisible included) was deleted, not only visible and checked as you described in previous post - this is correct from our point of view, because "Select all" was checked.
Anyways we strongly disagree with this "unchecking" functionality once you group records. It is confusing for our customers when grouping of records changing selection of rows in any way (visually or functionally).
Our desired functionality is to DO NOT change record selection and state of "Select all" checkbox during grouping. Grouping and selecting are two different functions and should not influence each other.

Note: We are using GridViewSelectAllCheckBoxMode.AllPages
Hello,
The SelectAllCheckboxMode property value is critical when selection is performed. In my previous post, I described the situation when SelectAllCheckboxMode is set to "Page". So, it is expected that the ASPxGridView behavior differs from yours when this property is set to "AllPages".
However, I understand your suggestions about the "AllPages" mode. I decided to forward this ticket to our developers for thorough research. We will keep you informed about our progress. Your time and cooperation are highly appreciated.
