How to make a valued field read only or non editable after the first save of a work item?

by Xavier Dilip Kumar 21. June 2016 20:47

Explanation:

I got a requirement to add a custom field for initial estimate which is required and should be read only or non editable after creating the work item.

Solution:

Solution is to add a FROZEN rule along with REQUIRED rule as follow

<FIELD name="Inital Estimate" refname="Custom.InitalEstimate" type="Double" reportable="Measures">

   <HELPTEXT>Inital estimate for this task</HELPTEXT>

   <FROZEN />

   <REQUIRED />

</FIELD>

Rule:

FROZEN - Prevents users from changing the value of a field once it contains a value. As soon as a user saves the work item with a value in that field, the value can no longer be modified.

REQUIRED - Requires a user to specify a value for the field. Users cannot save a work item until they have assigned values to all required fields.

XML parsing : illegal xml character migration error

by Xavier Dilip Kumar 15. March 2016 13:09

Exception:

Microsoft.TeamFoundation.Migration.Toolkit.ErrorManagement.MissingErrorRouterException: Runtime error does not meet the error routine policy and there is no conflict manager to log a conflict. ---> System.Data.UpdateException: An error occurred while updating the entries. See the InnerException for details. ---> System.Data.SqlClient.SqlException: XML parsing: line 1, character 78999, illegal xml character

Explanation:

This error might occur when stacktraces are pasted directly into the HTML fields in the work item. In my case, the stacktraces with illegal characters were in Repro Steps field.

Workaround:

I ignored the work items which were causing the failure using the below clause in the migration query.

And processed the ignored work items manually.
