I have been trying to install the latest version of Telerik controls on a clean development machine (not an upgrade, but fresh install).

The installer would always state that all was ok, but I was never able to get the Extensions or templates to install no matter how many uninstalls, reinstalls, and looking at others in the forum that have had similar issues.

I have followed the information from another forum (ASP.NET - as I have been having this issue with ALL of the telerik controls I downloaded as of 4/29/2011) that recommended I run the following method to log the issue:

msiexec /i [RadControlsInstallationMSIFileName].msi /limev InstallLog.txt

For the WinForms Controls - 2001.1.11.419 - I am getting the following error messages in the InstallLog.txt file:

So, if I'm reading this correctly, the VS Extensions are not installed due to an error in the MSI itself and not related to the new version of MSHelp or to UAC.  I have made bold the line I am referencing? 

I am installing on a clean install of MS Windows 7 x64 w/SP1, MS Office Pro 2010 and I have tried it with both Visual Studio 2010 Pro and Visual Studio 2010 Pro w/SP1 and get the same results.

While I can get the Extensions to install through Microsoft's Online Extension Gallery (VS -> Tools -> Extension Manager -> Online --> search for Telerik and install extensions), I have not seen this add any of the templates.  However, this does not appear to happen if I am running this as an upgrade? Or, maybe it is still failing, but the older templates are not updated (or there were no changes so nothing is needed to be updated).

Thanks for any assistance, and hope this can be resolved quickly.

In this sample, when you launch it:
-you can check the listviewitem called 'toto' (this call the AddDockTab() method)
-you can uncheck the listviewitem called 'toto' (this call the DelDockTab() method) but nothing happens.

Any idea ?

I have a treeview that is using the Office 2010 Black theme, and the expand icons in the treeview always display in a .NET form, but if the same control is opened in a VB6 form, the expand icons do not display. Everything else in the treeview seems to work fine. Have you seen this before?

I need to detect when the user changes pages by clicking on a tab. If certain conditions are not met, then I want to programmatically cancel the change. I see two events that might allow me to do this.

PageIndexChanging provides a CurrentIndex, NewIndex and Cancel properties. This would seem to do what I want but it does not fire when a page tab is clicked with a mouse.

SelectedPageChanging event does fire when the user clicks on a page tab. However, it does not contain a CurrentIndex, NewIndex or Cancel property. It does not seem to meet my needs.

What event should I use to detect when a user changes page tabs with a mouse and gives me programmatic control over the change?

thanks,

I have a grid with a role that formats the row in red if a specific decimalcolumn "Balance", calculated at grid initialization, contains a value that is less than 0. This rule is working fine.


In particular situations I need to override the above rule manually and to do so I have added a checkboxcolumn bound to the db and I am trying to add a new conditional rule which make the row green if the checkbox is checked. Obviously the status change of the checkboxcolumn happens at runtime.
I have tried in several ways but I cannot get it functional.
How can I change the formatting of the row (to green) at runtime if the checkbox is checked?

I'm sure I'm doing something wrong here, but I followed the documentation and it still doesn't seem to be working.  All I get is a blank item in my ListView.  Here's the code to recreate my issue.  The columns I've added to the control at design-time are named exactly what they indicate below.

I have a CommandBar that always displays tooltips when opened from a .NET form, but when the control containing the CommandBar is used in a VB6 form, the tooltips do not display. Have you seen this before?

How I can change the current time color?

I need to subtract two date from dateTimeColumns.

I tried in the designer:
DATEDIFFDAY(Periodo, Data_Pagam), in the designer

I tried with the code:

 radGridView1.Columns["Ritardo"].Expression = "Periodo-Data_Pagam";

I keep getting this error:
Invalid Expression:
"Cannot perform '-' operation on System.DateTime and System.DateTime

Please help.

I was looking at the Q2 2013 WinForms Controls demo. In the demo I liked the 'DOCK MDI Parent Form' sample. Where Can I download the sample code for this project?

See attached screen print.

Thanks
