HtmlAttributes on columns causes an "invalid template" error

[gm]

I am migrating an application from release 2012.3.1114 to release 2013.1.319.  Previously, I was able to apply HtmlAttributes on columns in this manner:

@(Html.Kendo().Grid<ToolListItemView>().Name("texListGrid")
    .Columns(columns => {
        columns.Bound(m => m.ToolId);
        columns.Bound(m => m.Description).HtmlAttributes(new { style = "font-size: 1.3em;" });
        columns.Bound(m => m.LastModified);
        columns.Bound(m => m.ConditionName);
        columns.Bound(m => m.LocationName);
    })
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("ToolsRead", "List").Data("listParams"))
    )
)

With release 2013.1.319, an "invalid template" error is generated from the above code.  If I change HtmlAttributes to HeaderHtmlAttributes, no errors are generated and the style is applied to the column header (i.e. the format of the HtmlAttributes isn't a problem).  I did verify that I could use HtmlAttibutes on a column with an @class parameter successfully, which is the correct way of applying styles.  I guess I'm wondering if this capability (local CSS styling via HtmlAttributes) was intentionally removed, or if I'm doing something wrong?

Note: Moved from Kendo UI Web forum.

Hi Gregg,

I think I remember somebody else talking about a similar issue, but we did not manage to reproduce it. Please check whether changing the style value makes any difference, e.g. try removing the space between ":" and "1".

On a side note, using custom CSS classes and external styles is a lot better than applying inline styles to multiple elements.

Hi Dimo,

Removing the spaces took care of the problem.  I agree that using classes is a better approach.  Actually, where I ran into problems was with a couple of columns where the content is acronyms.  I had been setting a title attribute so that when floating over the column a tool tip appeared with  what the acronyms meant (e.g. columns.Bound(m => m.ReleaseAcronym)..HtmlAttributes(new { title="R = Released, A = Archived" });  If I remove all the spaces it works.  I imagine there is a better way of displaying the information, but I went with the quick and dirty approach. :-)

It's not a big deal, I moved the title attribute to the header attributes, but there does seem to be a problem with any spaces in a html attribute value.  BTW, having spaces in the attribute value is not a problem when using HeaderHtmlAttributes.

Thanks, Gregg

Hello again,

We managed to track down the cause of the problem - it is the following declaration in the web.config:

<httpRuntime targetFramework="4.5" encoderType="System.Web.Security.AntiXss.AntiXssEncoder, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

It causes the spaces to be encoded, which leads to a parse error inside the internal Grid column template.

The issue is now fixed and changes will take effect in the next internal and official builds.
