[Solved] Recent Windows Update causing sizing issues

ADMIN UPDATE

This is a regression issue in IE: https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/11295665/.

Cast your vote by pressing the "+Me Too" button and encourage your end users to do the same if they have an account with Microsoft.

The problem with the RadWindow appearance will be fixed when Microsoft roll out a fix.

Cumulative updates through Windows Update should resolve the issue. First reported updates:

Windows 10: https://support.microsoft.com/en-us/help/4015217/windows-10-update-kb4015217.
Windows 7, Windows Server 2008: https://support.microsoft.com/en-us/help/4015549/windows-7-windows-server-2008-r2-sp1-update-kb4015549.

Fault condition description:

IE is in some form of compatibility mode (IE8, IE9 or IE10), usually via an meta tag. The issue does not manifest in standards (Edge) mode. Add a meta tag to enforce it.
RadWindow is in Classic RenderMode. It uses tables to render. Using the Lightweight RenderMode should alleviate the problem.
The end user machine has the KB4012204 update installed. Other updates that have been reported as associated with this issue: MS17-006, KB4012215, KB2952664, KB3216755, KB4013429, KB3218362.

END UPDATE

The recent Microsoft Windows Update seems to be causing issues for us with our .

https://support.microsoft.com/en-us/help/4012204/ms17-006-security-update-for-internet-explorer-march-14-2017

Attached is an example of what's happening since this update was pushed down.

Any suggestions on a quick fix?

Clients are IE 11 using Compatibility mode (v8).

[Solved] TreeList Header - Client-side Click event

Hi,

I am using the RadTreeList (Ajax) and trying to get a client-side click event for a left click on the header. This does not appear to be directly supported by the control. Is there an indirect way to get a client-side click event for the header row and determine the column of the event?

Thanks

how to prevent drag and drop of a folder

Hi,

At the opposite of selecting, droping could concern a folder. But this is not waht we want to do. We only want to allow files.

PS : I don't want to use allowed files extensions property because there are hundreds of extensions

Client Side Conditionally Expand Group Based on Value in Group Row

Hi,

I am able to expand/collapse my groups in Rad Grid on client side. What I would like to do is to cancel the expand/collapse in certain situations. For example, if the "Total" amount in my Group row is less than 100, I would like to cancel the expand event.

I know I should be able to do this by the GroupExpanding event - I have hooked that up (using GroupLoadMode = Client), and I can indeed intercept the expand event. However, I am not able to find a way to access the data in the group row I am expanding, to check what the total value is.

Is there a way to do this? I need to do this all client-side.

Basically, cancel the expand event if some value in the group row is not equal to 100.

Thanks

Daniel

if Manual Upload = true then Multiple File Selection feature doesn't work on IE9

Hi,

I encountered a problem on IE9. I used AsyncFile Upload control. I needed Manual Upload and Multiple File Selection. I could select only one file in the open file dialog on IE9 and the upload module was IFrame. But On Firefox I could select several files at a time. After I had switched off the Manual Upload feature I could select several files at a time on IE9 and the upload module was Silverlight. What should to do in order the Multiple File Selection feature works on IE9?

Environment: Win7 Ultimate x64 SP1, IIS7, VS2010 SP1, Silverlight 5, Telerik Radcontrols for ASP.NET Ajax Q3 2012 SP2 v.12.3.1308.0

There is my project in the attachment.

Thank you in advance.

Filterbox DELETE response

Hi,

When I compare the FileExplorer (EnableFilteringOnEnterPressed = True) with Windows behavior there is one issue a customer pointed me to.

Try the following scenario:

select a folder on the treeview screen, the items appear;
type a word in the filterbox, remove some characters using cursor select and BACKSPACE, everything OK;
type a word in the Filterbox, remove some characters using cursor select and DELETE, now the dialog appears if you want to delete the complete folder.

One customer had deleted complete folder by hitting OK. Not very clever of him but it can happen.

In the Windows Explorer this behavior is different; after DELETE the characters are just removed from the Searchbox and Search can be performed again.

When i start typing in listbox nothing happens.

For e.g if i want to search "Pain in thumb" it filters out fine in IE.

javascript firecommand and access controls from RadDataForm1_ItemCommand

I'm trying to fire a command from raddataform like:

var masterTable = $find("<%= RadDataForm1.ClientID %>");
masterTable.fireCommand("MyUploadCommand", "");

that fires very well and I can catch coomand in RadDataForm1_ItemCommand like:

If e.CommandName = "MyUploadCommand" Then......

but I cannot find controls inside <EditItemTemplate> no matter what. also very strange but inside Itemcommand routine e.DataFormItem.IsInEditMode is always false but its in edit mode.

I can access controls from RadDataForm1_Deletecommand, RadDataForm1_InsertCommand perfectly but not from RadDataForm1_ItemCommand.

How can I trigger a command with javascript and catch it and access controls ?

If I cannot find the answer I have to give up using raddataform because there are no documents left to read...

best.
