Change the behaviors of the embedded dialogs

HOW TO

Get reference to the embedded dialogs and change their parameters. The article shows how to change the size of the preview and upload RadWindows and the behaviors of the new folder and delete confirmation RadWindows, but all client-side methods of the window object can be used in order to change their properties.

SOLUTION

Resize the Preview window:

Example

ASP.NET

<telerik:RadFileExplorer runat="server" ID="RadFileExplorer1" Width="500px" Height="300px"
    OnClientFileOpen="OnExplorerFileOpen">
    <Configuration ViewPaths="~/ROOT" DeletePaths="~/ROOT" UploadPaths="~/ROOT" />
</telerik:RadFileExplorer>
<script>
function OnExplorerFileOpen(oExplorer, args)
{
    if (!args.get_item().isDirectory())
    {
        setTimeout(function ()
        {
            var oWindowManager = oExplorer.get_windowManager();
            var previewWinow = oWindowManager.getActiveWindow(); // Gets the current active widow.
            previewWinow.setSize(500, 500); // resize the window
            //previewWinow.maximize(); //alternatively, maximize it. You can use its entire API
        }, 100);   // Some timeout is required in order to allow the window to become active
    }
}
</script>

Note that some timeout is required in order to get the current active window.

Resize the Upload window:

1. In the OnClientLoad event of the FileExplorer get reference to the embedded RadWindowManager and  attach a handler to the OnClientShown event of the manager:  
    ````JavaScript
        var oWindowManager = oExplorer.get_windowManager();
        oWindowManager.add_show(windowIsShownHandler);
    ````
 2. In windowIsShownHandler call the handleOpenedWindow method after some timeout:  
        ````JavaScript
        // Called when a window is shown
        function windowIsShownHandler(oWindow, args)
        {
            setTimeout(function()
            {
                handleOpenedWindow(oWindow);
            }, 100); // Some time out is required as well
        }
        ````
 3. Implement the *handleOpenedWindow*function
    ````JavaScript
    function handleOpenedWindow(oWindow)
    {
        var oExplorer = $find("<%= RadFileExplorer1.ClientID %>");
        var windowTitile = oWindow.get_title();
    
        ////////////////////////////////////////////////////////////////////////////////////////
        /*
        Get the titles of the embedded radwindow objects.
        */
    
        // The title set to the RadWindowManager is the title shown in the Upload dialog
        // This code respects localization
        var uploadDialogTitle = oExplorer.get_windowManager().get_title();
    
        // The confirm dialog's title.
        // This title cannot be localized
        var deleteConfirmDialogTitle = "Delete";
    
        // The new folder dialog's title.
        // This code respects localization
        var newFolderDialogTitle = oExplorer.get_localization()["CreateNewFolder"];
    
        ////////////////////////////////////////////////////////////////////////////////////////
    
    
        switch (windowTitile)
        {
            case uploadDialogTitle:
                {// The upload dialog is opened
                    oWindow.setSize(500, 500);
                };
                break;
            case deleteConfirmDialogTitle:
                {// The delete confirmation dialog is opened
                    oWindow.set_behaviors(oWindow.get_behaviors() // get existing behaviors
                    +
                    Telerik.Web.UI.WindowBehaviors.Pin); // add "Pin" behavior to the current behaviors
                };
                break;
            case newFolderDialogTitle:
                {// The create new folder dialog is opened
                    oWindow.set_behaviors(oWindow.get_behaviors() // get existing behaviors
                    +
                Telerik.Web.UI.WindowBehaviors.Minimize); // add "Minimize" behavior to the current behaviors
                };
                break;
        }
    }
