Infragistics columnfilter

In my application i have used WebDataGrid Infragistics control. I have total 5 columns(Status,CandidateName,WorkOrderId,VenderName,Rate) in this grid. I needed to apply filter on 2 columns only i.e; Status and CandidateName. I have explicitly write code to set filter only in 2 columns. Below is my code. But, the problem is, Filter is applying on all the 5 columns regardless of setting the filter explicitly.

  <ColumnFilters>
   开发者_运维百科                     <ig:ColumnFilter ColumnKey="Status">
                                <ConditionWrapper>
                                    <ig:RuleTextNode Rule="Contains" />
                                </ConditionWrapper>
                         </ig:ColumnFilter>
                         <ig:ColumnFilter ColumnKey="CandidateName">
                                <ConditionWrapper>
                                    <ig:RuleTextNode Rule="Contains" />
                                </ConditionWrapper>                 
                          </ig:ColumnFilter>
 </ColumnFilters>

Please any one can tell me how to apply filter only on specific columns defined explicitly.

Thanks in Advance !!!!

You should be able to disable the other columns by setting Enabled=false as follows:

<Behaviors>
    <ig:Filtering>
        <ColumnSettings>
            <ig:ColumnFilteringSetting ColumnKey="WorkOrderId" Enabled="false" />
            <ig:ColumnFilteringSetting ColumnKey="VenderName" Enabled="false" />
            <ig:ColumnFilteringSetting ColumnKey="Rate" Enabled="false" />
        </ColumnSettings>
    </ig:Filtering>
</Behaviors>
