e.g.: When I prov

The documentation for getRowData states:

Do not use this method when you editing the row or cell. This will return the cell content and not the actuall value of the input element

Is the row still being edited when you call getRowData()?

Update

Agreed, jqGrid does not handle <select> very well. In my application I actually was able to get around this by not specifying an edit option (meaning, key/value were both "FedEx"); the translation to ID is then done on the server. This is not the right way to code this, but it worked well enough for my needs at the time.

You have to set the formatter of the column to 'select'

Example from the wiki:

colModel : [ {name:'myname', edittype:'select', formatter:'select', editoptions:{value:"1:One;2:Two"}} ... ]

See more here jqgridwiki

I was having the same problem and this worked like a charm

If in case you have requirement where each row has dropdown and it has values like

FE:'FedEx', IN:'InTime', TN:'TNT'

Now instead of saving the data to backend on dropdown change event;you want to save data on "Save" button click at row level but want to save dropdwon selected value (TN) not display text(TNT). You can create another hidden field to set selected country code on inline editing of dropdown. Here when user exit after cell inline editing afterSaveCell method will be called and you can set it as mentioned in below code:

生来不讨喜

I just solved this question by using setting JqGrid unformat option and use the following function for unformatting cell value.
```
function Unformat_Select(cellvalue, options, cellobject)
{
    var unformatValue = '';

    $.each(options.colModel.editoptions.value, function (k, value)
    {
        if (cellvalue == value)
        {
            unformatValue = k;
        }
    });

    return unformatValue;
}
```
The above method will be called everytime when grid need cell data like when you call "getRowData" method. However, my function only support key-paired value edit option. You need to change your data like the following pattern.
```
editoption: 
{
    value:
    {
        FE:'FedEx', 
        IN:'InTime', 
        TN:'TNT'
    }
}
```
For more information about unformat option, you can see at the following link.

JqGrid Wiki - Custom Formatter

PS. It's possible to modify my function to support client-side dropdownlist value. But I think it's impossible to apply this function for server-side dropdownlist value.

Update

In the latest jqGrid 3.8.1, I just found some bug when user cancel editing row(or programmatically call "restoreRow" method), jqGrid will create label by using key of data (instead of value of data). I create the following function to fix this issue. For use this, you must it as custom formatter function of this column. This function maps cell value to value of list by comparing key or value.
```
function JqGridInlineEditor_SelectFormatter(cellvalue, options, rowObject)
{
    var temp = '';
    $.each(options.colModel.editoptions.value, function (key, value)
    {
        if (cellvalue == key || cellvalue == value)
        {
            temp = value;
            return false;
        }
    });

    return temp;
}
```
So, you can send key or value as column data to be rendered by the above custom formatter.
