Examples
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 "";
}
Private Function GetMruList(selectedValue As String) As String
Dim state As StateBag = ViewState
If state.Count > 0 Then
Dim upperBound As Integer = state.Count
Dim keys(upperBound) As String
Dim values(upperBound) As StateItem
state.Keys.CopyTo(keys, 0)
state.Values.CopyTo(values, 0)
Dim options As New StringBuilder()
Dim i As Integer
For i = 0 To upperBound - 1
options.AppendFormat("<option {0} value={1}>{2}",IIf(selectedValue = keys(i), "selected", ""), keys(i), values(i).Value)
Next i
Return options.ToString()
End If
Return ""
End Function 'GetMruList
Remarks
These 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.
