ParameterCollectionEditor.EditValue Method

Definition

Edits the elements of the ParameterCollection objects of the associated data source control.

public:
 override System::Object ^ EditValue(System::ComponentModel::ITypeDescriptorContext ^ context, IServiceProvider ^ provider, System::Object ^ value);
public override object EditValue (System.ComponentModel.ITypeDescriptorContext context, IServiceProvider provider, object value);
override this.EditValue : System.ComponentModel.ITypeDescriptorContext * IServiceProvider * obj -> obj
Public Overrides Function EditValue (context As ITypeDescriptorContext, provider As IServiceProvider, value As Object) As Object

Parameters

context
ITypeDescriptorContext

An ITypeDescriptorContext object used to acquire context information.

provider
IServiceProvider

An object implementing the IServiceProvider through which editing services can be obtained.

value
Object

The object to edit the value for.

Returns

The new value; otherwise, if the value of the object has not changed, value unchanged.

Exceptions

value is null.

Remarks

The EditValue method extracts the associated data source control and the data source control designer that is associated with that control from the context parameter. The supported data source controls include the ObjectDataSource and SqlDataSource controls, with their corresponding ObjectDataSourceDesigner and SqlDataSourceDesigner designers.

Once the data is extracted, the EditValue calls back to the data source control designer to display an editing dialog box that is used to edit a ParameterCollection object that is referenced by one of the Parameters properties of the data source control.
