Greetings from Syncfusion.
Query 1: SfImageEditor has the DefaultSelectedColorIndex parameter that sets or gets the default color index in the palette.
We would like to let you know that DefaultSelectedColorIndex property is used to change the default selected color in color palette. Currently we can’t get the selected index in color palette using this property.
Query 2: How to get the color index that the user selected in the palette?
In our current implementation, we were unable to get the selected color index in the color palette. We would like to suggest that you can get the selected text or shape color by using the ItemSelected event and you can get the settings of each selected shapes and text using the ItemSelected argument. Please refer the help document below for more information.
Regards,
Ramya S
