Set Scroll Height by PageSizeCombo selected

[rik butcher]

guys, i'd like to be able to switch the ScrollHeight in the code behind based on the pageSize selected on the grid
we do this OnItemDataBound event and set the page size seletable to 15 & 30
if (e.Item is GridPagerItem)
{
RadComboBox PageSizeCombo = (RadComboBox)e.Item.FindControl("PageSizeComboBox");
PageSizeCombo.Items.Clear();
PageSizeCombo.Items.Add(new RadComboBoxItem("15"));
PageSizeCombo.FindItemByText("15").Attributes.Add("ownerTableViewId", InventoriesRadGrid.MasterTableView.ClientID);
PageSizeCombo.Items.Add(new RadComboBoxItem("30"));
PageSizeCombo.FindItemByText("30").Attributes.Add("ownerTableViewId", InventoriesRadGrid.MasterTableView.ClientID);
PageSizeCombo.FindItemByText(e.Item.OwnerTableView.PageSize.ToString()).Selected = true;
}
i've tried to punch into the events of the pagesizecombobox but it's not working - ANY IDEAS/ IM SURE IM MISSING SOMETHING SIMPLE
thanks
rik

ok, i think i've got this. if anyone knows of a more elegant way to do it, i'm open.

i hardcode: 
ScrollHeight="610px" in the client settings in the grid then add:

OnPageSizeChanged="PageChange" in the grid and use this & it seems to align w/ t he 15 or 30 row heights perfectly.


protected void PageChange(object sender, GridPageSizeChangedEventArgs e)
{
int newSize = e.NewPageSize;
if (newSize == 15)
{
InventoriesRadGrid.ClientSettings.Scrolling.ScrollHeight = 610;
}
else
{
InventoriesRadGrid.ClientSettings.Scrolling.ScrollHeight = 1320;
}
}

Hello Rik,

Handling the server-side OnPageSizeChanged event of the grid is the correct event for changing the ScrollHeight in your scenario. 

Generally, you do not need to search for the RadComboBox control and you can just use the event arguments and the e.NewPageSize in particular:

protected void RadGrid1_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)
{
    int pageSize = e.NewPageSize;
    double value = RadGrid1.ClientSettings.Scrolling.ScrollHeight.Value;

    if (pageSize == 15)
    {
        RadGrid1.ClientSettings.Scrolling.ScrollHeight = Unit.Pixel(610);
    }
    else
    {
        RadGrid1.ClientSettings.Scrolling.ScrollHeight = Unit.Pixel(1220);
    }
}
