Control.HasChildViewState Property
.NET Framework (current version)
Gets a value indicating whether the current server control's child controls have any saved view-state settings.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System.Booleantrue if any child controls have saved view state information; otherwise, false.
You can avoid unnecessary calls to the ClearChildViewState method by using this property to verify that any child controls of the server control are storing view-state information.
public override void DataBind() { base.OnDataBinding(EventArgs.Empty); // Reset the control's state. Controls.Clear(); // Check for HasChildViewState to avoid unnecessary calls to ClearChildViewState. if (HasChildViewState) ClearChildViewState(); ChildControlsCreated = true; if (!IsTrackingViewState) TrackViewState(); }
