Hi ermanRefaat, you can attach a FilterMethod to the FilterDelegate property of the shapefile provider before requesting data. However to style based on feature you want to look at themes 

I am not sure I understand your second question.. To symbolize a point you need to set the Symbol property of the layer's style or the style returned from any applied theme
