LoadCustomSettings event

LoadCustomSettings server-side event is raised by the LoadState() method of RadPersistenceManager and can be used to get previously stored custom settings

The example below demonstrates how to read the CustomSettings and pass them to a hidden field:

ASP.NET

<asp:HiddenField ID="wndStateHolder" runat="server" />

<telerik:RadPersistenceManager id="persistenceMngr" runat="server"
	OnSaveCustomSettings="persistenceMngr_SaveCustomSettings" OnLoadCustomSettings="persistenceMngr_LoadCustomSettings">
</telerik:RadPersistenceManager>

<telerik:RadButton RenderMode="Lightweight" ID="saveBtn" Text="Save State" runat="server" Width="67px" OnClick="saveBtn_Click">
</telerik:RadButton>
<telerik:RadButton RenderMode="Lightweight" ID="loadBtn" Text="Load State" runat="server" Width="67px" OnClick="loadBtn_Click">
</telerik:RadButton>

C#

protected void loadBtn_Click(object sender, EventArgs e)
{
	string fileId = Session["CustomPersistenceSettingsKey"].ToString();
	string FilePath = String.Format("{0}{2}{1}", MapPath("~/App_Data"), fileId, "\\");
	if (File.Exists(FilePath))
	{
		persistenceMngr.StorageProviderKey = fileId;
		persistenceMngr.LoadState();
	}
}

protected void persistenceMngr_LoadCustomSettings(object sender, Telerik.Web.UI.PersistenceManagerLoadStateEventArgs e)
{
	foreach (ControlSetting setting in e.CustomSettings.ControlSettings)
	{
		if (setting.Name == "pos")
			wndStateHolder.Value = (string)setting.Value;
	}
}

VB

Protected Sub loadBtn_Click(sender As Object, e As EventArgs)
	Dim fileId As String = Session("CustomPersistenceSettingsKey").ToString()
	Dim FilePath As String = [String].Format("{0}{2}{1}", MapPath("~/App_Data"), fileId, "\")
	If File.Exists(FilePath) Then
		persistenceMngr.StorageProviderKey = fileId
		persistenceMngr.LoadState()
	End If
End Sub

Protected Sub persistenceMngr_LoadCustomSettings(sender As Object, e As Telerik.Web.UI.PersistenceManagerLoadStateEventArgs)
	For Each setting As ControlSetting In e.CustomSettings.ControlSettings
		If setting.Name = "pos" Then
			wndStateHolder.Value = DirectCast(setting.Value, String)
		End If
	Next
End Sub
