StateBag.Keys Property
.NET Framework (current version)
Gets a collection of keys representing the items in the StateBag object.
Assembly: System.Web (in System.Web.dll)
Implements
IDictionary.KeysThese keys are the names of the control properties. For example, if you created a BGColor property on a Table control that you customized, a BGColor entry is created in this collection representing that property on your Table control.
These keys correspond to the names of the StateItem objects stored in the StateBag collection for the current page or server control.
You can iterate over this collection using the StateBag.GetEnumerator method.
The following code example demonstrates using the Keys property.
private string GetMruList(string selectedValue) { StateBag state = ViewState; if (state.Count > 0) { int upperBound = state.Count; string[] keys = new string[upperBound]; StateItem[] values = new StateItem[upperBound]; state.Keys.CopyTo(keys, 0); state.Values.CopyTo(values, 0); StringBuilder options = new StringBuilder(); for(int i = 0; i < upperBound; i++) { options.AppendFormat("<option {0} value={1}>{2}", (selectedValue == keys[i])?"selected":"", keys[i], values[i].Value); } return options.ToString(); } return ""; }
