Sql query to fetch only few records from 1 column based on Condition and show/display it separately using Select query

EDITED: In my Database table, I have 4 column ID ,Action, Name and DateTime with below records:

Action        Name         DateTime

Submit         AA        'date time'
Update         BB        'date time'
Save           CC          'date time'
Match           DD        'date time'
Submit          EE       'date time'
Submit          FF       'date time'
Update         GG      'date time'
Approve       HH    'date time'
Approve        II       'date time'
Update         JJ      'date time'
Match          KK       'date time'
Save           LL        'date time'
Match         MM      'date time'
etc                         'date time'
etc                         'date time'

These records can be repeate multiple time.

I want to select the Name and DateTime from above Table that has Action = Submit and Action = Update; into two separate columns using select query(Just like we get the data using select query).

Example Query:
SELECT Name as SubmitterName , DateTime AS SubmitterDateTime FROM [tbl_WorkflowHistory] Where Action = 'Submit'

SELECT Name as UpdateName , DateTime AS UpdateDateTime FROM [tbl_WorkflowHistory] Where Action = 'Update'

only thing is I want to show the records of both the query together but in 4 separate columns, like below Format:

Output Needed:

SubmitName     SubmitDateTime     UpdateName     UpdateDateTime

    AA                       'datetime'                     BB                       'datetime'
    EE                       'datetime'                     GG                       'datetime'
    FF                       'datetime'                      JJ                        'datetime'
    etc                                                           etc

Under "SubmitName" column, all Names shall come that has Action=Submit along with there respective DateTime in SubmitDateTime column.
Similarly, under "UpdateName" column, all all Names shall come that has Action=Update along with there respective DateTime in UpdateDateTime column. I dont know how to write this query, its just sample to explain my requirement.

And after selecting records like above Output, using sql query, I have to display it in a RadGrid in which data coming inside "SubmitDateTime" column have to show separately (Date separate , Time separate) in 2 different columms of RadGrid i.e., SubmitDate, SubmitTime. Similarly for "UpdateDateTime" i.e., UpdateDate, UpdateTime; as described as Below:

SubmitAction      SubmitDate     SubmitTime     UpdateAction     UpdateDate     UpdateTime

Submit                    'date'                 'time'             Update                    'date'              'time'
Submit                    'date'                 'time'             Update                    'date'              'time'
Submit                    'date'                 'time'             Update                    'date'              'time'
etc

I hope I made my requirement clear. Please let me know how to do this. I am using SQL server database. Please reply. Thanks in advance
