Hi,

I have added emoji's in my dashboard based on the expression.

Based on the percentage it has to show smiley with color as green and red.

Here i have written one method in javascript

function setColors(args) {
        var textClientData = DashboardViewer.GetItemData("textBoxDashboardItem1");
        var value = textClientData.GetMeasureValue(textClientData.GetMeasures()[2].Id).GetValue();
        if (value=="J")
        var result = value.toString().fontcolor("Green");
        document.getElementsByClassName('cs10E8CA05').css('color','Green');
        //x.style.color = "Green";
        //var score = $('#cs10E8CA05').text().trim();
        //var color = 'red';
        //$('#cs10E8CA05').css('color', color);
};

If the value is J then it has to be in green color.
If the value is L then it has to be in red color.

I have checked the network tab in browser and it is lying under the span.

How to set color for the span by using javascript call to css.

Please suggest me.

What I have tried:

function setColors(args) {
        var textClientData = DashboardViewer.GetItemData("textBoxDashboardItem1");
        var value = textClientData.GetMeasureValue(textClientData.GetMeasures()[2].Id).GetValue();
        if (value=="J")
        var result = value.toString().fontcolor("Green");
        document.getElementsByClassName('cs10E8CA05').css('color','Green');
        //x.style.color = "Green";
        //var score = $('#cs10E8CA05').text().trim();
        //var color = 'red';
        //$('#cs10E8CA05').css('color', color);
};

This is HTML

<span class="cs10E8CA05">L</span>

<span class="cs10E8CA05">J</span>

try

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
  
<body>
    <span class="cs10E8CA05">L</span> 
    <span class="cs10E8CA05">J</span>

    <script>
        var spans = document.getElementsByClassName('cs10E8CA05');
        for (var i = 0; i < spans.length; i++) {
            var span = spans[i];
            if (span.textContent == 'J')
                span.style.color = 'green';
            if (span.textContent == 'L')
                span.style.color = 'red';
        } 
    </script>
</body>
</html>

Hi Karthik,

Thank you for your information provided.

But here I have taken devexpress extension of dashboard for html.

@Html.DevExpress().DashboardViewer(settings => {
settings.Name = "DashboardViewer";
settings.Width = Unit.Percentage(100);
settings.Height = Unit.Percentage(200);
settings.CallbackRouteValues = new { Controller = "Home", Action = "DashboardViewerPartial" };
settings.ExportRouteValues = new { Controller = "Home", Action = "DashboardViewerPartialExport" };
settings.ClientSideEvents.ItemClick = "function(s, e) { getUnderlyingData(e); }";
settings.ClientSideEvents.ItemElementCustomColor = "function(s, e) { setColors(e); }";
//settings.ClientSideEvents.ItemVisualInteractivity = "function(s, e) { GetCalculatedFields(e); }";
}).BindToSource(Model).GetHtml()

In network tab it is showing span class for that emoji text.

Now my question where should i add the above code?

Or Can i change the color using javascript?
