How to scroll extJS grid on top from somewhere in middle or end without using focus












2















I have a button , textfield and grid with huge amount of data. What i am doing is i am typing some number and on click of button i want my grid to select and show in view taht pericular record.



Example if i select 1200 then it will go to 1200th record and show in view from scrolling.



For this I am doing



grid.getView().scrollIntoView(value)



This is working fine but for large data it is failing. So What i am doing here is



grid.getView().scrollDelta('Y',value*10,true);



This also working fine. But my problem is whenever i enter new value I want scroll to be start from top. I am trying to use this code grid.getView().focusRow( record ); and thing are working fine, but my focus getting changed.



I don't want my focus to be changed. Is there any other way I can start from the top.



Here is my code.



click : function(){
var view = this.getView();
var grid = view.down('myGrid');
var value = view.down('field').getValue();
//grid.getView().scrollIntoView(value);
grid.getView().focusRow( record ); // Trying to put on top but not by this way
grid.getView().scrollDelta('Y',value*10,true);
}


What is happening is suppose my value is 100, and if i enter new number then it is further scrolling down. (If I put 50 value it is scrolling to 150. I want to scroll 50 so i want to go on top first and then scroll again with having focus. )
