Why does the PivotGrid Postback so often?

Hi,

I use the 2015.1.401.40 version of your ASP.NET for AJAX controls.

If it matters, I'm currently binding it to a SQLDataSource.

From what I see, the entire PivotGrid does a PostBack when you:

- click a filter to display the Filter Popup

- expand or collapse a row or column field to show or hide detail

Why does it postback??? When I expand a row to show detail, and then collapse it, there is no reason to post back. I'm not even rebinding on postback. Why doesn't the control just use javascript to hide the detail.

The same with the filter popup... when you click the filter icon, why not just display a div that you could have put in the page when the control was initially bound? Why do a postback to then just display the filters in a popup?

Am I missing something or doing something wrong? Most of you other controls (hierarchical grid or grid with grouping), they are able to hide / show children or grouped rows on the client. Why doesn't the pivot grid?

Thanks,

Brent

Automatic Column UniqueName rename

Hi,

Recently I upgraded to Version 2015.1.401.45. After this upgrade, a column with name 'IsNew' that should be hidden. was displayed, although in the version before it is not displayed.

When debugging, I found out, that this column is renamed automatically to IsNew1. There is no other column with the same name in my datasource.

So I suppose, that with the new version IsNew is recognized to be a keyword??

This is the method for hiding columns:

private void HideColumns()

{

//set the visibility of columns defined in HiddenColumns to false

if (CGGrid.MasterTableView.Items.Count >= 0)

{

foreach (var item in HiddenColumns.Where(item => !String.IsNullOrEmpty(item)))

{

try

{

var column = CGGrid.MasterTableView.GetColumn(item);

if (column != null) column.Visible = false;

}

catch (Exception e)

{

LOGGER.Error(e);

}
