HTML Binary Image in HTML Textbox

[hamza]

I am setting the value of Html Textbox like below :

<img src="data:image/png;base64........" />

but the telerik report is showing blank white page instead of the image.

Is telerik report interprets image tag? or we can achieve that.

 

thanks.

Hi Hamza,

The HtmlTextBox item supports only certain text formatting option listed here.

If you want to display image, you can use the PictureBox item, where the base64 string will have to be converted to an Image object in code. For the purpose you can use a custom function to set the PictureBox.Value property which functi8on will be evaluated on processing the report and displaying it.


Let us know if you have any further questions.

Stef, could you not provide an example? 

I've been struggling with the same issue. Where the PictureBox control in the Telerik Report Designer program, plainly wont accept the Base64 image. Fine, we then convert it to Binary Data, but then the picture box shows a blank image. 

Is there no EXAMPLE anywhere??

Hi James,

Since R2 2020, we added the option to display a Base64 image in a PictureBox out-of-the-box. If upgrading is not possible for you, you can use the approach given in PictureBox Image as Base64.
