e.Value = CategoryEncodeTable[e.FieldValueInfo.Value.ToString()];
} else if(e.FieldValueInfo.Field == fieldProductName) {
string product =
ProductEncodeTable[e.FieldValueInfo.Value.ToString()];
string category =
CategoryEncodeTable[e.FieldValueInfo.GetHigherLevelFieldValue(fieldCategoryName).ToString()];
e.Value = product + '[' + category + ']';
}
}
if(e.ItemType == PivotChartItemType.ColumnItem) {
if(e.FieldValueInfo.ValueType == PivotGridValueType.GrandTotal) {
e.Value = "Total Sales";
