  • Reference

Definition

Namespace:
System.Web.DynamicData
Assembly:
System.Web.DynamicData.dll

Gets or sets a value that indicates whether empty string values ("") are automatically converted to null values when the data field is updated in the data source.

public:
 property bool ConvertEmptyStringToNull { bool get(); void set(bool value); };
public bool ConvertEmptyStringToNull { get; set; }
member this.ConvertEmptyStringToNull : bool with get, set
Public Property ConvertEmptyStringToNull As Boolean

Property Value

Boolean

true to automatically convert empty string values to null values; otherwise, false. The default is false.

Remarks

Sometimes the user might enter an empty string for a field value when updating or inserting records. Use the ConvertEmptyStringToNull property to specify whether an empty string value is automatically converted to null when the data field is updated in the data source.

By default, a DynamicField object displays null values as empty strings. To display a different value, set the NullDisplayText property.

Note

The Parameter object of the data source control that the parent control of DynamicField object is bound to also has a property named Parameter.ConvertEmptyStringToNull. This property performs the same function. Make sure that both properties are set appropriately.
