Hi,

These guys do not have reference to the System.Web.Extension and cannot find a class that inherits from default ScriptManager:

public ScriptManagerHelper(Control control)
{
    if (control.Page != null)
    {
        this.haveSM = true;
        foreach (DictionaryEntry entry in control.Page.Items)
        {
            if ((entry.Key.ToString().IndexOf("Microsoft.Web.UI.ScriptManager") >= 0) || (entry.Key.ToString().IndexOf("System.Web.UI.ScriptManager") >= 0))
            {
                this.isAjax = true;
                this.AjaxSM = entry.Value;
                this.smType = this.AjaxSM.GetType();
                if (this.smType.FullName == "AjaxControlToolkit.ToolkitScriptManager")
                {
                    this.smType = this.smType.BaseType;
                }
                break;
            }
        }
    }
}

Thanks Daniel,
How am I suppose to use the code?
Can I have VB.NET's version?
Thanks.

Hello,

The code shared by Vlad is not a workaround. He was trying to show you the reason for the error you depicted.

I recommend you replace our RadScriptManager control with the regular ScriptManager to ensure the normal operation of Obout controls in your scenario.

Thanks. Guess we will change code to use rotator.

From this reply it seems as if Telerik Controls are not compatible with Obout Controls. Please let us know as we are planning to use both in our application. Right now we are using Flyout HTML Editors etc from Obout and now need to integrate the GridView from Teleriks. It seems as if we will face problems in future.


Thanks and Regards

Why do you need the about html editors when you have the telerik ajax editor in place? It is far more advanced than the obout controls and does not have any conflicts with the other telerik ajax controls. You should give it a spin.

[Nabeel]

But we need to use our old controls to have legacy support. Please let us know in detail if it is possible to use old Telerik Controls or not.

Thanks very much

Since the release of DNN6, RadScriptManager seems to have become the default for all Partial Page Updates. This breaks all obout controls. Support from obout has been just silence so far so I'm hoping I can get a workaround here. Replacing the RadScriptManager is out of question as we don't control what DNN 6 does (at least not without much trouble). Is there any hope for those of us using obout controls?
