KineticScrolling fires ItemMouseClick event

[Lars]

Hello,

I am evaluating the new ListView with kinetic scrolling and discovered a strange behavior when releasing the mouse after a kinetic scroll - the ItemMouseClick event is fired and the item is also selected. Is there some way to avoid this?

Best Regards

Hi Lars,

Scary - We are doing much the same thing it seems, heres how I dealt with it temporarily:

private Point _downXY ;
private int _tolerance = 50;

private void lstSelect_ItemMouseDown(object sender, ListViewItemMouseEventArgs e)
{
  // Store press detection

  _downXY = Cursor.Position;

  // Find object key

  var selectedView = (DataRowView)e.Item.Value;
  _selectedUserId = Convert.ToInt32(selectedView.Row.ItemArray[0]);
}

private void lstSelect_ItemMouseUp(object sender, ListViewItemMouseEventArgs e)
{
  // Evaluate location

  var upXy = Cursor.Position;
  var xDiff = _downXY.X - upXy.X;
  var yDiff = _downXY.Y - upXy.Y;

  if (xDiff < 0)
  {
    xDiff = -xDiff;
  }

  if (yDiff < 0)
  {
    yDiff = -yDiff;
  }

  if (xDiff < _tolerance && yDiff < _tolerance)
  {
    // Select

    Close();
  }
}

Hope that helps.

Hello Alex,

Thanks for your reply and the suggested workaround fixes a part of the problem; I have more control over when to trigger a mouse click action, but the item (row) where the mouse is release is still being selected.

Hello Lars,

Thank you for writing.

@Alex: Thank you for the community effort. 

@Lars: Currently this is the default behavior of RadListView when kinetic scrolling is executed. However, your suggestion seems quite reasonable, and this is why I have added it to our PITS system as a feature request, which we will implement in a future release. Please follow this link to add your vote for this request and increase its priority. 

I have updated your Telerik points for this suggestion.

Should you have any other questions, do not hesitate to contact us.

Kind regards,
Stefan
the Telerik team
