<script type="text/javascript">
        function setPageSize(item) {
            var size = parseInt(item.getValue());
            if (size == 0)
            {
                var height = Viewport_Main.getHeight();

            PagingToolbar.pageSize = size;

                                                    <Listeners>
                                                        <Select Handler="setPageSize(item);" />
                                                    </Listeners>
                                                </ext:ComboBox>
</ext:PagingToolbar>

When I select any item, e.g 20, the store is reload, but grid show 19 row only(1-19), lost the 20th, when select item 30, show 1-29, lost one, and I press next button, show 31-60, and I press prev button, show 1-30, the lost record comeback, why? I check html source in IE9, the lost record i found, but don't show in grid.

Hi,

How is the Store configured?

Could you provide a full sample to reproduce the problem?

Sorry, isn't bug. My GridPanel is remote paging, in the Store OnRefreshData function, normal, e.Start is zero, but fire by

PagingToolbar.doLoad()

, e.Start is -1. I solve it by following code:

string start = e.Start.ToString();
if( start == "-1" )
    start = "0";
