[Solved] Column Client Template that refers to another column's value.

[Matt]

Hello,

I'm putting together a demo evaluating the Telerik controls, and I'm trying to define a grid column that has a template that depending on the value of that column displays one of two images.  I want to include the value from another column as an attribute for later use in the image's click handler, but am receiving a javascript error if I refer to any column other than the current one in the template.  Here is what I am doing:

cols.Bound(c=> c.LabelCount).
                ClientTemplate("<# if (LabelCount > 0)"
                + " { return '<img src=\"..."\" onclick=\"LabelClicked(this)\"  EntryId = \"<#= Id #>\"  />'; } else "
                + "{ return '<img src=\"...(disabled version)"\"    />'; } #>")

This gives me an Invalid character  error from telerik.grid.min.js however.  If I replace <#= Id #>
 with <#= LabelCount #> everything works fine(except for not giving me the data I want).  I've tried prefixing Id with c. and dataItem. with no success.  What's the proper way to do this, or if it's impossible for some reason how can I achieve clicking the image calling a javascript function with another columns value as a parameter?  I'm using MVC Q3 2011.

Hi Matt,

Try this:

ClientTemplate("<#= getImage(LabelCount, Id) #>")


<script>

function getImage(labelCount, id) {
    if (labelCount > 0) {
          return '<img src=".."'>';
    } else {
          return '<img src=".."'>';
     }
}

</script>
