...Hi,I am using ExtJS 4.2 in my apllication and facing the same problem.i tried with lot solution with help of google but i couldn't. Anyone have Override or plugin for this problem.Please Suggest some solutions to solve.&amp;amp;nbsp;
I was working diligently on this issue. It took me forever to trace through the framework to figure out where this was occuring but I finally figured it out. It will depend on a case by case basis but what makes the table jump is a call to 'doLayout' on the grid panel when a click occurs. For each case you must target a 'before' event to turn off layouts like this -> grid.suspendLayouts(); . Then, in the 'after' event turn layouts back on -> grid.resumeLayouts().
because of some strange reason, the itemclick and beforeitemclick events are not firing at all. but beforeselect and select do. I tried to suspend layout there.
suspendLayouts() and resumeLayouts() are not available in 4.0.7. I tried using grid.suspendLayout = true; and grid.suspendLayout(true); but they dont seem to help (I am not unsuspending layouts just to make sure that the jump doesnt take place) but still no progress... the effect happens in FF and IE (havent tested in Chrome).
I also tried using the override with row selection model and checked the code of onRowMouseDown in later versions (4.2.2) but that doesnt seem to fix it either.
from my investigation, i found that the focusRow method of Ext.view.Table is the problem. Here it tries to calculate the "adjustment" based on selected record and then calls panel.scrollByDeltaY(adjustment); This causes the view to jump.
Currently, I have overridden onLastFocusChanged method of Ext.selection.RowModel (which I am using in my grid) and put supressFocus = true; in it so that it doesnt try to focus the rows. This stops the jumping of the view but the disadvantage is that the scrolling wont work when the user moves cursor up/down to move selection. So may be its not the best way to solve it but in my application, it might just do.
