Keep scrolling position after editing

[CSharpSeraph]

Hi,

great work guys, I'm using it for very big charts that take lots of space both vertical and horizontal. I made the date cells editable so the user can edit the durations live. The problem is that after editing a value, e.g. very low in the scroll top position, the chart gets rendered again and it pulls back the user to x:0 y:0. Is there a "clean" way to keep the scroll position after changing values?

thanks a lot!

Well, is possible to add a listener to keep saving the last x,y position.. and then when the render methods runs again, set this 2 values again on the scroll

Hi! Yes, I tweaked the .js that way and it works just fine!

Awesome!! could u please share with us?

Yup!

on

this.Draw = function () {

I have declared the variables:

    var CUR_SCROLL_TOP = 0; 
    var CUR_SCROLL_LEFT = 0;

after declaring the name of the very first container, but BEFORE creating it:

var newId = '#' + this.vDivId + 'gchartbody';

as first thing I save the positions. Please note that the very first time they won't be recorded because the main div does not exist yet, but after the first render I'll have an exising instance of the div to record the position, before the function destroys it and builds it again:

CUR_SCROLL_TOP = $(newId).scrollTop(); CUR_SCROLL_LEFT = $(newId).scrollLeft();

then at the very end, after :

this.drawComplete(vMinDate, vColWidth, bd);

I set the previous positions:

    if (CUR_SCROLL_TOP > 0) {

        $(newId).scrollTop(CUR_SCROLL_TOP);
    }
    if (CUR_SCROLL_LEFT > 0) {

$(newId).scrollLeft(CUR_SCROLL_LEFT);
    }
