RadGrid cannot edit in IE8 under 2014Q2
javascript thows errors:
URI: http://localhost/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3azh-CN%3a8f393b2b-3315....

To fix the upper problem, we appyied 2014Q2SP1, however, in IE8, javascript thows new errors:
“sys is undefined” 
and the RadGrid does not display in web. But this is ok in debuging mode.

The title says it all. Right now there's only a check all option.

In the out of the box Grid CheckList filter the only way to clear all items for a checklist filter once filter items have been selected is to:

1) Uncheck each one individually
2) Click "Check All" to check all, then click "Check All" again to uncheck all.

It would be great to just have a clear all/clear selection button in the filter list.

The functionalities listed below are officially not supported with multicolumn headers: 
•Frozen Columns;
•Show/Hide on the client;

Please provide the solution for these known issues in next release

When trying to batch edit cell values of the Grid via e.g., RadEditor (GridHTMLEditorColumn or RadEditor in EditItemTemplate of GridTemplateColumn) the cell value always result to a plain text. 

Hi Telerik,

The suggestion here is to be able to Copy and Paste (Ctrl-C and Ctrl-V) values from one cell in a column to other selected cells in the same column, when in Batch EditMode.  I currently have this working through javascript functions but maybe going too deep in the RadGrid control to get things to work and the internals of the control sometimes change from one version to another. Thus it might be better to embed this functionality in the control.

In order to better explain I included an attached word document describing what I am talking about with screenshots.

Thanks for you consideration, Jim

Hello,

Pls find attached file mentioning expected display for responsive radgrid behaviour

Add support for custom paging in the RadGrid Virtualization functionality. The idea is to enable the retrieval of part of the data from the source of data instead of retrieving all of the data every time.

Without this feature the optimization technique is to cache the data source.
