Exchange the star with custom symbol?

[Marcus Köny]

Hi,

is it possible to exchange the star symbol in SfRating control with a custom symbol, for example a circle?

Best regards

Marcus

Hi Marcus,

Thank you for contacting Syncfusion support

We have prepared a sample which tries to meet your requirement. In the sample we have changed the Data for the Path by editing the style of the SfRatingItem

Please download the sample from the below link
Sample link:SfRatingSample_(2)

Please let us know if you have any concern

Hi,

thank you for the quick response. I am much later now...

I had to port the sample to "Desktop WPF" and I now get a Nullpointer Exception when leaving with the mouse. (Stack trace at the end of thsi reply).

The modifications I made are attached as file.( Second part)

I am shure something ist still wrong with the handler. I made some experiment, but could not find it out.

Best regards

Marcus

Hi Marcus,

Sorry for the inconvenience caused.

On analyzing your source code which you have sent in the last update, we found that the LinearClipper is removed from the template of the SfRatingItem.We have processed the LinearClipper in the Source code, so you have faced this NullException. You can avoid this exception by adding the LinearClipper in the SfRatingItem Template.

We have modified the sample and you can download the same from the below link
Sample link : SfRatingWPFSample

Please try our solution and also let us know if you need a patch for this fix? So that we would provide assistance according to your reply.

Please let us know if you have any other concern,
