Grid DetailTemplate, condition expression of accessing SubGrid value

[HSO]

Hello:

I have a Master/Child grid structure like so:

Parent Grid:

 @(Html.Kendo().Grid<ElementViewModel>()
.Name("gridEle")
.Columns(cols =>
{
    cols.Bound(e => e.EleNum)
})
.DataSource(dataSource => dataSource
    .Ajax()
    .Read(read => read.Action("GetElements", "Rating", pi))
)
.ClientDetailTemplateId("tempSubEle")
)

Child Grid as DetailTemplate:

<script id="tempSubEle" type="text/kendo-tmpl">

@(Html.Kendo().Grid<SubElementViewModel>()
.Name("gridSubEle_#=EleID#")
.Columns(cols =>
{
    cols.Bound(e => e.Rating)
        .ClientTemplate("<input type='checkbox' value='1' " +
                        "#if(Rating==1){#checked='checked'#}# />" );
})
.DataSource(dataSource => dataSource
            .Ajax()
            .Read(read => read.Action("GetSubElementsByElementID", "Rating", new { eID = "#= EleID #" }))
)
.ToClientTemplate()
)
    </script>

The Problem:

I have a #if{# ... #}# statement in the column ClientTemplate, however the Rating value is from the Parent Grid not the current Child Grid (Parent Grid happen has a column also named 'Rating'), to prove that it is from Parent Grid,  if I change Rating to a column that only exists in the Child grid, i.e. SubEleID, it gives error at browser, saying that SubEleID is not found.

The Question:
so what is the syntax for Rating gets the Child Grid value?
just for the sake of trying, I even tried: data.Rating, or $(this).Rating, none worked.

Please advise,
Thank you

Hello Jason,

As the detail Grid is inside client template all other client templates /i.e column ClientTemplate/ must escape the `#` symbols.

In your case the template for the column will become as this:

cols.Bound(e => e.Rating)
 .ClientTemplate("<input type='checkbox' value='1' " +
  "\\#if(SubEleID==1){\\#checked='checked'\\#}\\# />" );
