Silver chloride is an ionic compound then why doesnt it dissociate when put in water rather than decomposing it through sunlight? And alao why its is insoluble in water eventhough it is ionic compound?

Silver chloride is an ionic compound but, the polarity difference between the two ions is not large enough to get ionise in the water.
A compound is soluble in water when its ''solubility product > ionic product.''
In case of AgCl, solubility product < ionic product.
The forces holding the solid AgCl lattice together are too strong to be overcome by the forces favoring the formation of the hydrated ions, Ag+(aq) and Cl-(aq).
Hence, it remains insoluble in water and get decomposed in sunlight.
