    I'm not sure I understand the question.  I'm not sure that editorDataField

    can be a dot-expression.

    I think the CB will be given the from_Name to display, but the dataprovider

    is full of usernames so it may not match up.

    the dataprovider for the datagrid  only have 500 record and the CB dataprovider have only 6 records ? and if that was the problem what to  do i dont think this is the problem is there any limits for number of recortds to use in the dataprviders in case of finiding the matchies , ?!

    The amount of entries does not matter in your case.

     

    If you take your items one by one ( each item found in the dataGrid dataProvider ), does the item[ Est_Mandob ] correspond to an item found in the Combobox's dataProvider ?  Combobox's set data makes use of dataField when used within a dataGrid.

    yes i agree that the amount of data does not matter , and yes the item {Est_Mandob} correspond to an item found in the Combobox's dataProvider


    i copyed the code of the custom componant and i created an aplication to take a look of it , this is the link

     

    http://msmdk.selfip.com:8500/newexp/bin/Dispatching_test.html

     

    the idea of this aplication that any of this records should be updated and removed from the datagrid if the user chose the Est_mandob field

    and all this records have its est_mandob but only 2 or 3 at the top of records have the correct est_mandobe wetch exist in the CB dataprovider but the rest records needs to be updated
