### ANY_VALUE {#ANY-VALUE}
```
public static final int ANY_VALUE
```


Any value validation type.

### BOOLEAN {#BOOLEAN}
```
public static final int BOOLEAN
```


TRUE or FALSE

### CHECK_BOX {#CHECK-BOX}
```
public static final int CHECK_BOX

### CUSTOM_FUNCTION {#CUSTOM-FUNCTION}
```
public static final int CUSTOM_FUNCTION
```


Custom javascript function validation.

**Remarks**

Use the ClientValidationFunction property to specify the client validation function's name. The function should be declared as this formation:
function customValicationFunction(source, value)
The parameter "source" is the cell object. The parameter "value" is the string value of a cell to be checked. The function should returns true if the value is valid.

### CUSTOM_SERVER_FUNCTION {#CUSTOM-SERVER-FUNCTION}
```
public static final int CUSTOM_SERVER_FUNCTION
```


Custom server-side function validation.

**Remarks**

Use the CustomServerFunction property to specify the serverside validation . below is the example code:
first define class which implement GridCustomServerValidation class myservervali : GridCustomServerValidation
...... then add validation var gridValidationCollection = this.GridWeb.ActiveSheet.Validations;
GridValidation gv = gridValidationCollection.Add(new GridCellArea(1, 1, 2, 2));
gv.ValidationType = GridValidationType.CustomServerFunction; gv.ServerValidation = new myservervali(); then set ClientValidationFunction to deal with client logic when server validation fails and return message gv.ClientValidationFunction = "ValidationErrorClientFunction"; the client function shall be declared like this: function ValidationErrorClientFunction(cell,msg) please check demo page for a detail reference
