public CascadingDropDownNameValue[] GetAllDistrict(string knownCategoryValues, string cate

want to know whether i can pass more than two arguments in the above shown webservice method..i intend to implement it in a cascading drop down list.. having two sibling dropdown lists...

so i want to pass three arguments eg..cid, brid, deptid...but a webservice allows only two of the kind...

Hi,

You can pass more information via a third parameter contextKey. For instance:

public static AjaxControlToolkit.CascadingDropDownNameValue[]
GetDropDownContentsPageMethod(string knownCategoryValues, string category, string contextKey)

protected void Page_Load(object sender, EventArgs e)
{
CascadingDropDown2.ContextKey = "contextKeyOf2";
}

Hope this helps.
