顶级值更改时重置字段值 [英] Resetting the field values when top level value changes

问题描述

大家好，

我有一个控件，它有多个（3）字段，并且它们在工作项类型中有相应的值。

I have a control which has multiple (3) fields and they have corresponding values in work item type.

我不希望所有字段都应该选择一个值。每当我在其他字段中选择值时，自动选择的其他值应自动重置。这可能吗？

I dont want all the fields should have a value selected. Whenever i select the value in other field, automatically other values which was already selected should reset. Is this possible?

谢谢，

Raj

嗨Raj，

关系是什么你的3场价值？可以< when>和< copy>规则符合你的要求吗？

What's the relationship of your 3 fields value? Could <when> and <copy> rules meet your requirement?

我举一个例子，当level1选择AAA，level2改为AAA，level3改为111。

I make an example, when level1 choose AAA, level2 change to AAA, level3 change to 111.

 < ; FIELD name =" Level1" refname = QUOT; Custom.Level" type =" String">

        < ALLOWEDVALUES expanditems =" true">

          < LISTITEM value =" AAA" />
$
          < LISTITEM value =" BBB" />
$
          < LISTITEM value =" CCC" />
$
        < / ALLOWEDVALUES>

      < / FIELD>

      < FIELD name =" Level2" refname = QUOT; Custom.Level2" type =" String">

        < WHEN field =" Custom.Level" value =" AAA">

          < COPY from =" value"值= QUOT; AAA" />
$
        < / WHEN>

        < WHEN field =" Custom.Level" value =" CCC">

          < COPY from =" value"值= QUOT; CCC" />
$
        < / WHEN>

        < WHEN field =" Custom.Level" value =" BBB">

          < COPY from =" value"值= QUOT; BBB" />
$
        < / WHEN>

        < ALLOWEDVALUES expanditems =" true">

          < LISTITEM value =" AAA" />
$
          < LISTITEM value =" BBB" />
$
          < LISTITEM value =" CCC" />
$
        < / ALLOWEDVALUES>

      < / FIELD>

      < FIELD name =" Level3" refname = QUOT; Custom.Level3" type =" String">

        < WHEN field =" Custom.Level" value =" AAA">

          < COPY from =" value"值= QUOT; 111" />
$
        < / WHEN>

        < WHEN field =" Custom.Level" value =" CCC">

          < COPY from =" value"值= QUOT; 333" />
$
        < / WHEN>

        < WHEN field =" Custom.Level" value =" BBB">

          < COPY from =" value"值= QUOT; 222" />
$
        < / WHEN>

        < ALLOWEDVALUES expanditems =" true">

          < LISTITEM value =" 111" />
$
          < LISTITEM value =" 222" />
$
          < LISTITEM value =" 333" />
$
        < / ALLOWEDVALUES>

      < / FIELD>
