Hello Andrea,

I suggest you debug your code and see which element is null on this line:

string strProductType = cboProductType.CurrentValue.Replace("*", "%");

If cboProductType.CurrentValue returns null, then there’s no value entered for the WebDropDown and the CurrentValue returning null is expected.

In that case you can check if the value is null and it it’s null just set it to an empty string :

  string strProductType = "";

        if (cboProductType.CurrentValue !=null)

        {

            strProductType = cboProductType.CurrentValue.Replace("*", "%");

        }
