Hello, I am looking for support with the radwindowmanager and the autosize and autosize behavior properties...I've been trying to implement the same scenario as these two links:


no luck... I always need to have a width and a height coming from the codebehind, else it only displays a small square. I am not sure if this is cause by the way the app is programmed...anyway hope somebody can jump in and help out. is the code driving the window: 

starts here:
                            url: "/Pages/Inventory/Add_Product.aspx", 
                            width: 800, 
                            height: 550, 
                            title: "Add Product", 
                            modal: true, 
                            javascriptOnClientClose: "OnClientClose", 
                            page: Page

goes to here:


public void OpenRadWindow(string url, int width, int height, string title, bool modal, WindowBehaviors behaviors, bool showDuringLoad, string javascriptOnClientClose, Page page)
            RadWindowManager winMgr = null;

            winMgr = (RadWindowManager)page.Master.FindControl("RadWindowManager_Global");

            if (winMgr != null)
                RadWindow radWindowForm = new RadWindow();
                radWindowForm.ID = "radWindowForm_" + Guid.NewGuid().ToString();
                radWindowForm.MinWidth = new System.Web.UI.WebControls.Unit(width,System.Web.UI.WebControls.UnitType.Pixel);
                radWindowForm.MinHeight = new System.Web.UI.WebControls.Unit(height, System.Web.UI.WebControls.UnitType.Pixel);
                radWindowForm.AutoSize = true;
                radWindowForm.AutoSizeBehaviors = WindowAutoSizeBehaviors.Default;
                radWindowForm.Title = title;
                radWindowForm.Modal = modal;
                radWindowForm.NavigateUrl = url;
                radWindowForm.Behaviors = behaviors; 
                radWindowForm.EnableShadow = true;
                radWindowForm.EnableTheming = true;
                radWindowForm.KeepInScreenBounds = true;
                radWindowForm.ShowContentDuringLoad = showDuringLoad;
                radWindowForm.VisibleStatusbar = false;
                radWindowForm.VisibleOnPageLoad = true;
                radWindowForm.OnClientClose = javascriptOnClientClose;
                winMgr.EnableViewState = false;

this is the control in master page:


<telerik:RadWindowManager ID="RadWindowManager_Global" runat="server" AutoSize="true" AutoSizeBehaviors="Default" Style="z-index: 7001" />

thanks for the support. I will add additional info if needed.

Hello Andrey,

The AutoSize behavior of RadWindow greatly depends on the HTML content that is rendered. The configuration seems accurate to me, but with some markup example of the content you want to load I can only assume why the AutoSize does not work as expected.

Generally, you should make sure that the content rendered has fixed width and/or height, which will expand the size of the RadWindow.
