Fast scrolling results in white space in grid for a moment

[preeti_kanyal]

Hi Isomorphic;
My SmartGWT version is: 'v11.0p_2017-02-11/PowerEdition Deployment (built 2017-02-11)'.
My application is using SmartGWT + Spring + Hibernate

I have a list grid which fetches data from DataSource with DataFetchMode = Basic so all the data is provided to grid at once.(No Paging)
But still when user scrolls down the page , user experiences white space in grid for a moment.
How to get rid of this white space in scrolling?

Hi preethi,

see setDrawAheadRatio() and setDrawAllMaxCells(). Note that latter is about cells, not rows.

Hello Blama ,

I have used this setDrawAheadRatio() property. But due to this property multiple fetch calls are generated. Can we restrain that extra fetch calls or is there any some other way around to achieve this functionality?

Hi preeti_kanyal,

if the property makes the white space less, then it is working as expected. If it also creates another fetch, this is most likely a bug.
You'll need to create a testcase for Isomorphic then.
