Set webservice parameters using script

[tinus1975]

Hi,

I've got a form with a dependent dropdown list. Because the dependent
list can contain a lot of values I want to retrieve the values when the
dropdown it is dependent on has it's value changed.

The way I want to do this is to show the firstdropdown with a button
next to it. When the user selects a value and presses the button the
webservice that is the data source for the dependent dropdown is called
with the value of the first dropdown as a parameter.

Problem is that I can call the webservice (using JScript), but I don't
know how to set the input parameters for the webservice.

Does anybody have any idea on how to do this?
Many thanks,
Tijn.

1. Open data sources task pane, select your web service's datasource and
look at it's structure: there is the node, that holds input parameter
2. select this node from XDocument.DataObjects('...').DOM
3. set node's text to whatever you need.
4. call XDocument.DataObjects('...').Query() method
