Tooltip External HTML file


does anybody have any experience with the tooltip in the radzen components?

I could use it with a simple STRING in my code and also the type documented here for for ShowTooltipWithHtml works.

But i want to be able to have a complete HTML file as a seperate file which should be shown as a tooltip. If i create a seperate file, it is showing all the HTML tags as string chars.

Is there any possibility to reference a external HTML file?


Blazor does HTML encoding by default. You can check online how to display HTML in Blazor using the MarkupString class.

Hi Korchev,

thanks for the quick Reply. MarkupStrings in C# was indeed the last test i also tried to solve my issue but in fact it is the place im stuck.

The TooltipService is not accepting any MarkupString.

I tried this for example:

@code {
MarkupString fileResult = new MarkupString(File.ReadAllText(@"Pages\Test\Test.html"));

Do you have me any example, how i can handover a MarkupString to the TooltipService?

I just checked and indeed the Radzen Tooltip currently does not support HTML content. We may add support for this in a future release.
