Scroll to specified DataView item

[John-Mickael]

Hello,

I'm new in sencha touch, and did not found any solution to my problem.

I have a Tab Panel. On the first tab, i have a List with an XTemplate and on the second tab, i have a dataView with an XTemplate. The same informations are displayed on both panels, but the first tab is a summary and the second tab display the complete content, therefore there is a scrollbar.

When i choose an item on the List, i switch to the second tab, and try to scroll the DataView in order to show the related item.

I tried unsucessfully to use method presented here : http://www.sencha.com/forum/showthre...em-in-dataview

I hope someone could help me.

Thanks.
JM

I found a solution in the following thread : http://www.sencha.com/forum/showthre...ew+scroll+item

I had to change some little thinks :
1) i replace the second's panel DataView by a List
2) in the itemtap event of the first list i memorize the index of the selected item, and set the second tab as activeitem
3) in the cardswitch event of the tabpanel i scroll to the position of the second list, if the newCard is the second panel.

cardswitch : function ( t, newCard, oldCard, index, animated ) {        	  		
	         	  		if (newCard.id == 'newsPanel') {
	         	  		   listId = push.selectedItem; //The index of selected item in first list
	         	  		   if (listId != null)
	 	                   {  
	 	                   	push.pushDataViewNews.scroller.scrollTo({x:0,y:0}, false);

	 	                    push.pushDataViewNews.select(listId);

	 	                    var ehtml = push.pushDataViewNews.getNode(listId);
	 	                    var el = Ext.get(ehtml);	 	                   	 	                    
	 	                    var ykor =    el.getY(); //-push.pushDataViewNews.getHeight(); I had to remove this for a succefull scroll
	 	                    var xkor =  el.getX();

	 	                    push.pushDataViewNews.scroller.scrollTo({x:xkor,y:ykor}, true);
	 	                    
	 	                   push.selectedItem = null;
	 	                    
	 	                   }  
	         	  		}
	         	  		
	         	  	}
