Conditionally enable/disable command button

When the grid is filled I want to conditionally enable/disable a command button in a column depending on the value of a item in that row.  This should do done on a per row basis and when it's filled, not just when it's in edit state.

I have the following, just can't figure out the details:

.......
        <e-column header-text="Supplier" width="100">
            <e-column-commands>
                <e-column-command type="Details">
                    <e-button-options click="onGetPO" text="Get"></e-button-options>
                </e-column-command>
            </e-column-commands>
        </e-column>
......

JavaScript

     What event should this be in? 
            if (this.getCurrentViewData()[args.rowIndex]["Supplier"] == "xyz") {
                   Set the command button to enabled
            else
                  Set the command button to disabled
            }
       

Thanks,
Mike

Hi Michael, 

Thanks for contacting Syncfusion support. 

We have analyzed your query. We suspect that you want to disable the button in a command column when data gets loaded in grid. We suggest you to use the query-cell-info event of Grid. And to disable the button we suggest you to set the enabled property of ejButton to false. Please refer the documentation link below, 

Please refer the code example below, 

<ej-grid id="TagsGrid" allow-paging="true" datasource="@ViewBag.dataSource" query-cell-info="cellinfo"> 
            ... 
           <e-columns> 
                ... 
               <e-column header-Text="Manage Records"> 
                    <e-column-commands> 
                        <e-column-command type="edit"> 
                            <e-button-options content-type="TextOnly" text="Edit"></e-button-options> 
                        </e-column-command> 
                    </e-column-commands> 
                </e-column> 
            </e-columns> 
</ej-grid> 
 
<script type="text/javascript"> 
    function cellinfo(e) { 
        if (e.column["headerText"] == "Manage Records" && e.data["customerID"] == "ANATR") { 
            $(e.cell).find('.e-button').ejButton({ enabled: false }); //disable the button in the manage record column. 
        } 
    } 
</script>
