# GridFooter

###

You can create a footer for grid columns. The value for "column" specifies the target column.

The following parameter can be supplied:

* **“column”:** name for the target column
* **“select”:** will specify the Range for data selection. Possible values are **“all”** or **“visible”**. **“all”** is the default setting and will select all available data from this column. With **“visible”** only data matching a selection will be processed. If no selection is active, all data will be shown.
* **“action”:** will specify what action will be taken for the given data. Possible values are **“sum”**, **“avg”** (average), **“min”** (minimum), **“max”** (maximum). **“sum”** is the default.
* **“decimalDigits”:** If you are using a config based grid the decimal digit setting will be inherited from the column setting. Otherwise the default will be 0. If u want to overwrite this behavior this setting can be used.
* **“textLeading”:** Add a text in front of the value.
* **“textTrailing”:** Add a text behind the value.

```
//the following will give a sum for all data for the column "cordGrossValue"
[
   {
      "column":"cordGrossValue"
   } 
]

//the following will give an average for the visible data within a selection. If no selection is activ all data will be processed
[
   {
      "column":"cordGrossValue",
      "select":"visible",
      "action":"avg"
   } 
]


//the following will give one decimal digit for the value and add leading and trailing text. e.g. "Total: 123.4 $"
[
   {
      "column":"cordGrossValue",
      "decimalDigits": 1,
      "textLeading": "Total: ",
      "textTrailing": " $",
   }
