Range selection not possible when using mouse dragging with mouse wheel scrolling

[Claas Philipp]

Hello,

it is not possible to use mouse dragging in conjunction with mouse wheel scrolling when using 'enableRangeSelection' for control 'ejs-filemanager' when the user wants to select more rows than there are currently visible. The items in the upper rows get de-selected when scrolling downwards.

For reference, use the 'Preview Sample' function for https://ej2.syncfusion.com/angular/documentation/file-manager/multiple-selection#enabling-range-selection, copy multiple of the existing files to the same folder, for example in 'Files > Picture > Employees', to ensure there are more rows than currently visible, select the first picture, press the left mouse button, drag downwards and scroll downwards. Please also see the attached screencast. Would it be possible for you to provide a solution for this? Thanks in advance.

Hi Claas Philipp,

  

The issue  “Range selection not possible when using mouse dragging with mouse wheel scrolling” has been resolved in this release. To access this fix, we suggest you update the package to the latest version(33.2.4). We have also included the sample in the main version for your reference.

Root cause: Scroll event not binded to container element. Previously, dragSelect element is appended to this.viewElem which does not contains scroll so the issue occurs.

Sample: https://stackblitz.com/edit/angular-hs3cut2m-dpxqm59j?file=src%2Fstyles.css
