SSRS 2016 Report Viewer V13 Toolbar Icons not disp

Question

When i was looking solution for the problem, i saw a topic on microsoft forums. The same question is asked by a user and i want to quote that question:

The Report Viewer control is not rendering the toolbar correctly.

I'm following the instruction Getting started with the ReportViewer 2016 control at https://msdn.microsoft.com/en-us/library/mt764770.aspx and am able to run reports from my application, however there are issues with the Report Toolbar.

1. I'm not seeing the toolbar icons, even though the hyperlinks are active.

2. When I open the Export dropdown the background is transparent and difficult to read.

3. Report parameter dropdowns appear as textboxes, yet when I click them they act like dropdowns.

Attached is an image showing the toolbar as it is rendering in my application:

Answer 1

From what I can see this is still an issue, Microsoft still haven't released an update to correct the missing icons when using a Master/Child Page.

I got the control working in a normal ASPX page and took a look at how the icons were being displayed, it looks like a in-line style tag is generated per control instance.

As a temporary work around until Microsoft release a fix for this you can use the style tag below, i pulled this from the in-line css.

The content values from an answer above got mixed up. Here are the correct values:

.glyphui-calendar:before {
    content: "H";
}

.glyphui-powerbi:before {
    content: "E";
}

.glyphui-refresh:before {
    content: "F";
}

.glyphui-back:before {
    content: "G";
}

.glyphui-firstpage:before {
    content: "A";
}

.glyphui-lastpage:before {
    content: "B";
}

.glyphui-previouspage:before {
    content: "C";
}

.glyphui-nextpage:before {
    content: "D";
}

.glyphui-downarrow:before {
    content: "K";
}

.glyphui-save:before {
    content: "J";
}

.glyphui-print:before {
    content: "I";
}

Are you using the control in a master/child page? There is a known issue with the current Report Viewer Control RC - https://github.com/Microsoft/Reporting-Services/blob/master/Docs/Get-Started-With-RVC.md#known-issues
