asp.net mvc - Custom Telerik DataViz chart tooltip color -

i have chart many colors. tooltip should appear black or white depending on background color of chart's bar. option can think of handle series.name. nothing works.

this code accurately put white or black piece of text onto screen tooltip:

.tooltip(tooltip =>     tooltip.visible(true).template("# if ((series.name === 'foo') || (series.name === 'bah')) { return '<strong style=\"color: black\">bar</strong>'; } else { return '<strong style=\"color: white\">bar</strong>'; } #") ) 

however, once plug in #= series.name # #= value # instead of bar function breaks down , no longer works.

next, tried both sharedtemplate , template such (one @ time of course):

.tooltip(tooltip =>    tooltip.visible(true).template("mytemplate")    tooltip.visible(true).sharedtemplate("mytemplate") )  <script id="mytemplate" type="text/x-kendo-template">    # if ((series.name === 'foo') || (series.name === 'bah')) { #       <strong style="color: black">bar</strong>    # } else { #       <strong style="color: white">bar</strong>    # } # </script> 

this didn't , instead displayed tooltip of "mytemplate".

is possible do? if not there kind of work around?

the answer set tooltip color on series itself:

 .series(series => {     series.column(new double[] { 1, 2, 3}).name("india").tooltip(t=>t.background("#fff"));     series.column(new double[] { 4, 5, 6 }).name("russian federation").tooltip(t => t.background("#000"));     series.column(new double[] { 7, 8, 9}).name("germany").tooltip(t => t.background("#fff")); })
