whats the equivalent ItemDataBound event for silverlight rad grid ?

[Bibhudutta]

I want to set the cell values of a particular column in the silverlight rad grid. i know we can do that in the asp.net ajax rad grid using the ItemDataBound Event, in this manner :

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        string originalValue = item["MaskedColumnUniqueName"].Text;
        //implement masking logic here and update originalValue to masked value
        item["MaskedColumnUniqueName"].Text = originalValue;
    }
}

But how can i acheive that in the silverlight rad grid, it has no ItemDataBound event.

Please help me out.
