[Solved] Ajaxmanagerproxy vs button disable

Hello

I have an issue with RadajaxManagerProxy in a Masterpage/contentpage setup.
My goal is to enable/disable (save/update/email) buttons upon saving/updating a telerik report.

The code provided below works just fine when executed under no load.

But during the day with multiple users online, the script stops enabling/disabling the buttons.
(savereport and other heavy rutines still works)

Is my approach incorrect for the task?
Any help would be highly appreciated.

regards

Mark

How to extract RadGrid EditableItem into a DataTable?

Is it possible to extract the edited row from a RadGrid into a DataTable object?

The examples I've seen online show how to extract the data into a HashTable, but once you do that, you lose the data type (string, datetime, ect). We're building a generic grid that can display different tables, so we don't want to have to hard code the columns/data types. If the data is in a DataTable, then it can be passed directly to a SQL stored procedure that accepts a Table Value Parameter.

Viewstate Compression with SSRS 2012 ReportViewer and IE11

A client site is running our ASP.NET 3.5 web-application which includes the Report Viewer control for reporting. They have recently upgraded to IE11, which must be run in native/standards mode.

In order to get the print function of the Report Viewer control working, we have upgraded the Report Viewer control to the 2012 version and have applied patches / updates as per instructions here:
https://blogs.msdn.microsoft.com/selvar/2013/12/20/reportviewer-2012-control-not-showing-print-icon-when-viewed-from-ie-11-desktop-mode/

Part of these instructions are to remove any browser files, however we are currently using the RadHiddenFieldPageStateCompression utility to compress viewstate (specified as per Telerik documentation in the Default.browser file).

If we remove the Default.browser file, the Report Viewer print function operates correctly, but viewstate compression no longer works. Adding the Default.browser file back in, hides the print button on the Report Viewer control.

Is there any way that we can retain viewstate compression and use the SSRS 2012 Report Viewer print function?

Thanks.

Disable drag and drop beteen grids

Hi

Is it possible to disable the possibilty to drag and drop between multiple grids on one page?
The only method I've found to disallow drag and drop between mutliple grids is to check if the source and target grid are the same on dropping otherwise canceling.
