ASPxFileManager.JSProperties Property

Enables you to supply any server data that can then be parsed on the client.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

public Dictionary<string, object> JSProperties { get; }

VB.NET

Public ReadOnly Property JSProperties As Dictionary(Of String, Object)

Property Value

Type	Description
Dictionary<String, Object>	The collection of property names and their values.

Remarks

In some instances, it is necessary to obtain server information on the client. The JSProperties property enables you to declare temporary client properties. The JSProperties property represents a collection of property names and their values. Once declared, a property can be accessed on the client.

Note

The only requirement is that property names must begin with the ‘cp’ prefix, to avoid rewriting the ASPxFileManager‘s base properties.

Example

The code below demonstrates how you can show information about folder contents in a label.

C#

public string ItemsNumberToString(int count, string item) {
        if (count != 1) item = item + "s";
        return count.ToString() + " " + item;
}
protected void ASPxFileManager1_Load(object sender, EventArgs e) {
        int FileCount = ASPxFileManager1.SelectedFolder.GetFiles().Length;
        int FolderCount = ASPxFileManager1.SelectedFolder.GetFolders().Length;
        ASPxFileManager1.JSProperties["cpLabelText"] = "The " + ASPxFileManager1.SelectedFolder.Name + " folder contains " + ItemsNumberToString(FolderCount, "folder") + " and " + ItemsNumberToString(FileCount, "file");
}
