RadEditor Toolsfile causes error

[Paul]

Hi. I want a simplified configuration of the RadEditor. However, I get an error:

"The string parameter 'key' cannot be null or empty"

All I have done is create a new page and add an Editor control. That obviously runs fine. I've created an "Editor" directory in my site and copy BasicTools.xml (from the telerik demos). I then set the editor control's ToolsFile property to reference the xml. Just making that change causes the site not to run and I get the above error message. What's wrong?

Hi Paul,

I tried to reproduce the problem using the provided information but to no avail.

This error might occur you have used a separator (<tool separator="true"/>) in a context menu which is not correct and causes the error. If this is not the case, could you please provide more detailed information on the subject? Could you please provide the used tools file, and the RadEditor's configuration? Also, which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?

Looking forward to hearing from you,

For me it takes 30 seconds to replicate the problem. I've just created a new web form (with a master but the master has little in it and works fine).
With the new blank page I just drop a RadEditor control onto the page. If I run the page it works fine and the editor works no problem (as it should).
Back in design mode I select the RadEditor and in properties set the ToolsFile to an xml file that I copied from the Telerik directories. That is all that I do. If I then run the page it fails to run with the error message.

If I look at the page source it is:

The xml file that I copied over was BasicTools.xml and its entire content is:

      <tool name="FindAndReplace" />
        <tool separator="true"/>
        <tool name="Undo" />
        <tool name="Redo" />
        <tool separator="true"/>
        <tool name="Cut" />
        <tool name="Copy" />
        <tool name="Paste" />
    </tools>

    <tools name="Formatting" >
        <tool name="Bold" />
        <tool name="Italic" />
        <tool name="Underline" />
        <tool separator="true"/>
        <tool name="ForeColor" />
        <tool name="BackColor"/>
        <tool separator="true"/>
        <tool name="FontName"/>
        <tool name="RealFontSize"/>
    </tools>

</root>

There is a separator but I just copied the xml file so assumed all was ok. All I want is a minimal configuration editor. Thanks

[Paul]

I've just deleted all of the separator items from the xml so that it is:

<root>

    <tools name="MainToolbar" >
      <tool name="FindAndReplace" />
        <tool name="Undo" />
        <tool name="Redo" />
        <tool name="Cut" />
        <tool name="Copy" />
        <tool name="Paste" />
    </tools>

    <tools name="Formatting" >
        <tool name="Bold" />
        <tool name="Italic" />
        <tool name="Underline" />
        <tool name="ForeColor" />
        <tool name="BackColor"/>
        <tool name="FontName"/>
        <tool name="RealFontSize"/>
    </tools>

</root>

I deleted the RadEditor from the page, dropped a new RadEditor onto the page and set its ToolsFile to the xml file ==> same problem, doesn't run

Hi Paul,

Thank you for the additional information. The problem seems to be related to the fact that the tools are configured twice when using the VisualStudio design time to set the RadEditor's ToolsFile property in .NET 4.0. I have logged this issue to our database and we will do our best to fix it for one of the upcoming releases.

For the time being, in order to avoid this problem you can either remove the separators from the toolsfile or remove the inline registration of the tools from the code that is automatically generated from the .

As a small token of gratitude I have updated your Telerik points.

I am getting this same error. In your reply, you did not finish your sentence... Below is what you said...

Generated from the what???

thanks,

[Roger Manderville]

I find that if I delete the markup added when the toolfile was specified and just leave the reference to the toolfile then it works fine.

thanks,
Roger

Hi Roger,

Please accept my sincere apologies.
