Hi Mouni,

If you want to use GetFeatureById, the id should be a number for example "1", "5" etc. The 2nd parameter is which column you want to read, the value can be found in the feature.ColumnValues.

I think you should want get the feature based on your column "UID", so the API should be:

Feature feature = shapeFileLayer.FeatureSource.GetFeaturesByColumnValue("UID", "PR71_1")[0];

You can refer the sample: 9288.zip (99.4 KB)

Wish that's helpful.
