Use data from urls as the suggested values of a multivalue control

How to get started

Visual Studio Team Services

Navigate to your work item form customization page and add a rest multivalue control.

Edit the control so it can use the right field to store your selection and the right url/property combination to be displayed. For example

https://<account>.visualstudio.com/<project>/_apis/build/definitions?api-version=3.0

name

If the name is specified it look for the first array in the response and get that property of the array of returned objects.

If property: name

Valid response body:

{
    value: [
        {name: 'a'},
        {name: 'b'},
        {name: 'c'}
    ]
}

If left blank it will look for the first array in the response and use that (response can just be an array of string too). Example response

{
    value: ['1','2',3']
}

On Premises

Navigate the process template xml. For each work item type to customize at the location

/WITD/WORKITEMTYPE/FORM/WebLayout/Extensions

add

<Extension Id="ottostreifel.vsts-rest-multivalue-control" />

Within the same Weblayout choose a group element and add

              <ControlContribution Id="ottostreifel.vsts-rest-multivalue-control.multivalue-form-control" Label="<control name>"  >
                <Inputs>
                  <Input Id="FieldName" Value="<longtext field reference name>" />
                  <Input Id="Url" Value="<url>" />
                  <Input Id="Property" Value="<property path>" />
                </Inputs>
              </ControlContribution>

How to query

The selected values are stored in a semicolon separated format. To search for items that have a specific value use the "Contains Words" operator. If searching for multiple values, use multipe "Contains Words" clauses for that field.

Alternatively if the Property field starts with '$' it will use the JSONPath Syntax

Example:

Url

https://<account>.visualstudio.com/<project>/_apis/wit/workitemtypes?api-version=3.0

Property

$.value[*].icon.id
