So i have some large project for which i am creating a sample of migration from Ext.Net 1.6 to Ext.Net 2.1 with MVC 4. Doing so i have stumbled upon the Error, that (after making my web-application conform with my Master Page) the renderer for my GridColumn throws following Errors:

Uncaught TypeError: Object function String() { [native code] } has no method 'format' 
Uncaught TypeError: Cannot call method 'removeChild' of null

the renderer is in the "HeadContent" Placeholder while the GridPanel is in "MainContent"

Renderer function looks as follows: 

<script type="text/javascript">
    var template = '<span style="color:{0};">{1}</span>';

    var listname = function (value, meta, record) {
        return String.format(template, (record.data.blockstatus == "free") ? "green" : "red", value);
    };
</script>

a general sample page for the use of ext.net does work without any problems.

Any Ideas on how to fix this?

In Ext JS 4, the String.format was removed and replaced with the Ext.String.format function. More information available in the Ext JS documentation, see

http://docs.sencha.com/ext-js/4-2/#!/api/Ext.String-method-format

Also see item #40 of the Ext.NET 2.0 Breaking Changes,

http://examples.ext.net/#/Getting_Started/Introduction/BREAKING_CHANGES/

Hope this helps.
