ESRI.ArcGIS.ADF.Web.DataSources Namespace > IGISResource Interface : SaveState Method

Visual Basic (Declaration)

Visual Basic (Usage)

C#

Save the state of the GIS resource.

Syntax

Visual Basic (Declaration)
Sub SaveState()

Visual Basic (Usage)	Copy Code
Dim instance As IGISResource instance.SaveState()

C#
void SaveState()

Example

The GIS resource instance is stored in the hashtable managed by its GIS data source. The key is a user defined value to uniquely identify a resource. The key should be unique for resource definition in case the resource definition changes at runtime.

C#	Copy Code
public virtual void SaveState() { if (dataSource == null) return; if (dataSource.State == null) return; dataSource.State[key] = this; } internal string key { get { return string.Format("{0}:{1}:{2}", this.GetType(), Name, ResourceDefinition); } }

Copy Code

public virtual void SaveState()
{
    if (dataSource == null) return;
    if (dataSource.State == null) return;
    dataSource.State[key] = this;
}
        
internal string key
{
    get
    { 
      return string.Format("{0}:{1}:{2}", this.GetType(), Name, ResourceDefinition); 
    }
}

Remarks

The SaveState method is often used to save an instance of the GIS resource in state. If a resource is managed by a resource manager control, the SaveViewState event during the page lifecycle will call SaveState on the resource. Developers should define a custom key to identify the GIS resource value.
