AutoCompleteBox add control programmatically error

I have:
1. An user control: Pub.ascx. The user control has a RadAutoCompleteBox. I bind data for the RadAutoCompleteBox in Page_Load event of Pub.ascx.
2. A webpage: Test.aspx. The page has a button btnAdd and a panel pnlPubs. When I click on Add, the page load user control Pub.ascx then add it to the panel pnlPubs.

Now I can see the user control Pub.ascx on the panel. However, when I try to use the RadAutocompleteBox, it shows me error:
"The target 'ctl02$rbConf' for the callback could not be found or did not implement ICallbackEventHandler."

Would you please help me solving this problem? I really need to add AutoCompleteBox programmatically.

Thank you.

RadGrid Virtualization and Selction of Rows

Hi All -

I just downloaded the latest version of Telerik (Q3 2103)to take advantage of the new Virtualization features in the radgrid. The scrolling works perfectly for 300,000 records! However, I have a GridClientSelectColumn in my grid so that user can chose to select rows by clicking on individual rows, as well as to click the header to "select all". With the virtualization, it can't select all, but selects only those records in the current view. I did notice that the new version does support persisting row selections across pages. I assume this is happening client side (because when I set the items per view to 500+, the performance goes way down).

What's the best way to implement a select all and de-select all for a grid that is virtualized?

Thanks!

Christy

PivotGrid with OLAP, displaying a parent-child hierarchy

Hi,

I have succesfully connected a SSAS 2012 OLAP Cube with PivotGrid component with ADOMD connection. However, I'm having difficulties with displaying a parent-child hierarchy, which has a self-referencing field. PivotGrid seems to flatten my hierarchy and it's not showing hierachical summaries as Excel PivotTable component.

Should parent-child hierarchies work with PivotGrid? Will it be available in the future?

Best Regards,
Mikko Luukkonen

Resetting Insert/Edit Mode Programmatically

Is there a way to cancel the Insert (Add New Record) or Edit mode programmatically?

I am binding the RadGrid based on what the user selects in a DropDown. However, if they click on "Add New Record" or Edit in the RadGrid, even after the RadGrid is re-databound, it still maintains its Insert/Edit State. I want to start on a clean slate (RadGrid is neither inserting or editing).

<ChartTitle Text="Ops Server Percentage">

<Appearance>

Preserving dates in date range

Right now we are storing filtering in the session so that whenever a user returns to the grid, their filter options are still preserved. Everything is working great, except for the values that were in the date range. For all the other columns, I was able to specify column.CurrentFilterValue = "something" and then the respective filter text box would reflect "something." However, when I try this same technique for my date range column, it does nothing, and the "From" and "To" textboxes are just blank, but the grid's filtering is still preserved.

How can I reset these values on date range columns?

Thank you for your help
