dynamic binding

[Former Member]

Hi All,

I have a context node "header" and it has two context attributes "att1" , "att2"

att1 is of type string

att2 is mapped to a simple dictionary (having hardcoded values for the drop down)

In the view i have 2 dropdown

dropdown1 with values "A" , "B"

My requirement is when i chose "A" from the 1st drop down

The second drop down should be mapped to att1

if i chose B from the 1st drop down

The second drop down should be mapped to att2

Thanks

Suresh

Hi Suresh,

Please use this code:

// I am assuming that the value of the first dropdown is stored in context attribute "DropDownValue" which is directly under context node. 
// Please use appropriate attribute name if it differs.
String value  = wdContext.currentContextElement().getDropDownValue();
IWDDropDownByKey DDK = (IWDDropDownByKey)view.getElement("DROP_DOWN_ID");
if(value.equalsIgnoreCase("A")){
	IWDAttributeInfo attrinfo = wdContext.nodeHeader().getNodeInfo().getAttribute("Attr1");
	DDK.bindSelectedKey(attrinfo);
}
else if(value.equalsIgnoreCase("B")){
	IWDAttributeInfo attrinfo = wdContext.nodeHeader().getNodeInfo().getAttribute("Attr2");
	DDK.bindSelectedKey(attrinfo);
}

I hope this solves the issue. Please revert back in case you need any further information on this.

Thanks and Regards,

Hi suresh,,

This code should be written in wdDoModify method in View controller

String value = wdContext.currentContextElement().getDropDownValue();

IWDDropDownByKey DDK = (IWDDropDownByKey)view.getElement("DROP_DOWN_ID1");

IWDDropDownByKey DDK1 = (IWDDropDownByKey)view.getElement("DROP_DOWN_ID2");

if(value.equalsIgnoreCase("A")){

IWDAttributeInfo attrinfo = wdContext.nodeHeader().getNodeInfo().getAttribute("Attr1");

DDK1.bindSelectedKey(attrinfo);

}

else if(value.equalsIgnoreCase("B")){

IWDAttributeInfo attrinfo = wdContext.nodeHeader().getNodeInfo().getAttribute("Attr2");

DDK.bindSelectedKey(attrinfo);

}

Thanks
