Compiler Error Message: CS1061: 'def2_aspx' does not contain a definition for 'DropDownList2_SelectedIndexChanged' and no extension method 'DropDownList2_SelectedIndexChanged' accepting a first argument of type 'def2_aspx' could be found (are you missing a using directive or an assembly reference?)

In your code behind page def2_aspx.cs, make sure you check
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{} is there. In your code behind page, there is no reference for DropDownList2_SelectedIndexChanged method. I think there is some spelling mistake in DropDownList2_SelectedIndexChanged method at code behind page. Check you method if any typo error, then your issue will be resolved.
