Master Page Display Issue

Hello,

I have successfully upgraded my sites from Kentico CMS 6.0 to 7.0.

I am using the Portal Page template and get the following error when loading the Page tab of the master page:

There was an error processing the page. The error can be caused by the configuration of some component on the master page. Check the master page configuration or see event log for more details. Original message: The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.

Does anyone have a solution for this?


Kentico Legend	Brenden Kehren - 1/11/2014 9:48:08 PM RE:Master Page Display Issue Do you have any <%= %> blocks on your master page? If so, this could cause problems. Have you checked your event logs to see for more specific error?

RE:Master Page Display Issue

Hello.

If you get this error message you may need to modify the code of your web part, so that it doesn't display any content on the Design tab - for example:

[C#]

using CMS.PortalEngine;

public override void OnContentLoaded()
{
base.OnContentLoaded();
if ((this.PagePlaceholder.ViewMode == ViewModeEnum.Design)
|| (this.HideOnCurrentPage) || (!this.IsVisible))
{
this.Repeater1.DataSourceID = "";
this.CMSRepeater1.StopProcessing = true;
}
}

Also, is there any additional info in your Event log in Site Manager / Administration section? Thank you.

Best Regards,
Radek Macalik
