[Solved] Popup Window in iFrame?How to fix it center?

hi!

I'm using a javascript to launch a window.

    
            <script type="text/javascript">  
        
                function openRadWin()  
        
                {  
        
                    radopen("http://www.telerik.com","RadWindow1");   
        
                }  
        
            </script>

The problem is that this window is launched inside a frame.

I want to know :

If this launched window can be moved out of the frame? or be blocked inside of the frame?
How to popup it in screen center? but not in frame center.

In a word, how to popup the window from iframe, fixing it in screen center and moving out of the frame?

In my page, left side is a masterpage and right side there is an iframe in it, maybe like this demo effects:
http://demos.telerik.com/aspnet-ajax/window/examples/radopen/defaultcs.aspx

If luanching window in iframe can't make this effects, is it necessary to popup a window from main page where the iframe is contained?

Hope I described the situation clearly, thank you!

RadWindow causes page reload

Hi, I have a button to programatically build the url for one RadWindow, but I have some strange problem showing the window, after the Window is closed, every control that must initiate an Ajax request forces a page reload on postback and the window apperas again.

This is my code on the page

    <script type="text/javascript">

    function OpenFreqWindow()
    {
        var mgr = $find('RadWindowManager1'); // GetRadWindowManager();
//        alert(mgr);
        mgr.show();
        return false;
    }
    function OpenWindow(url)
    {
        var mgr = $find('RadWindowManager1'); // GetRadWindowManager();
        //alert(mgr);
        var wnd = mgr.open(url, null);
        return false;
    }
    </script>

this is the RadWindowManager

    <telerik:RadWindowManager ID="RadWindowManager1" runat="server" Skin="Vista" Animation="None" Behavior="Default" Behaviors="Default" InitialBehavior="None" InitialBehaviors="None" Left="" Top="">
        <Windows>
            <telerik:RadWindow runat="server" Animation="None" Behavior="Default" Behaviors="Default"
                InitialBehavior="None" InitialBehaviors="None" Left="" NavigateUrl=""
                Skin="Vista" Style="display: none;" Top="" Modal="True" Width="500px" Height="500px">
            </telerik:RadWindow>
        </Windows>
    </telerik:RadWindowManager>

the code behind

    protected void btnShowWindow_Click(object sender, EventArgs e)
    {
            String url = "SomePage.aspx?source=fromWindow";
            GridItemCollection items = RadGrid1.Items;
            foreach (GridDataItem item in items)
            {
                TableCell cell = item["CheckBoxTemplateColumn"];
                CheckBox chkItem = cell.Controls[1] as CheckBox;
                if (chkItem.Checked)
                {
                    ++docCount;
                    url += "&doc"+docCount.ToString()+"=" + item["CustomerID"].Text;
                }
            }
            InjectScript.Text = "<script type='text/javascript'>Sys.Application.add_load(function(){OpenWindow('" + url + "')})</script>";
        }
    }

Can somebody help me with this issue? I've spent 2 days trying to figure out what's wrong

Any help would be appreciated

Thanks in advance

Programatically create RadGrid

RadGrid

r = new RadGrid();

r.MasterTableView.DataKeyNames =

new string[] { "DepartmentID" };

r.Skin =

"Default";

r.Width =

Unit.Percentage(100);

r.PageSize = 5;

r.AllowPaging =

true;

r.AutoGenerateColumns =

false;

r.MasterTableView.PageSize = 15;

//Add columns

GridBoundColumn boundColumn;

boundColumn =

new GridBoundColumn();

boundColumn.DataField =

"DepartmentID";

boundColumn.HeaderText =

"DepartmentID";

r.MasterTableView.Columns.Add(boundColumn);

boundColumn =

new GridBoundColumn();

boundColumn.DataField =

"Budget";

boundColumn.HeaderText =

"Budget";

r.MasterTableView.Columns.Add(boundColumn);

//Detail table - Orders (II in hierarchy level)

GridTableView tableViewOrders = new GridTableView(r);

//tableViewOrders.DataSourceID = "AccessDataSource2";

tableViewOrders.DataKeyNames =

new string[] { "CourseID" };

GridRelationFields relationFields = new GridRelationFields();

relationFields.MasterKeyField =

"DepartmentID";

relationFields.DetailKeyField =

"DepartmentID";

tableViewOrders.ParentTableRelation.Add(relationFields);

RadGrid1.MasterTableView.DetailTables.Add(tableViewOrders);

//Add columns

boundColumn =

new GridBoundColumn();

boundColumn.DataField =

"CourseID";

boundColumn.HeaderText =

"CourseID";

tableViewOrders.Columns.Add(boundColumn);

boundColumn =

new GridBoundColumn();

boundColumn.DataField =

"Title";

boundColumn.HeaderText =

"Title";

tableViewOrders.Columns.Add(boundColumn);

r.AllowMultiRowSelection =

true;

r.MasterTableView.DetailTables.Add(tableViewOrders);

r.DetailTableDataBind +=

new GridDetailTableDataBindEventHandler(r_DetailTableDataBind);

r.NeedDataSource +=

new GridNeedDataSourceEventHandler(r_NeedDataSource);

r.ID =

"RockOn";

this.PlaceHolder1.Controls.Add(r);

its the same code posted on Site Examples..

it loads ok but when i try to expand the grid Row ... i get an error--

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

on page load i m binding the DataSets to the Grid

Multi-column Treeview

I was wondering if there is a way to do a 2 column treeview? My treeview is simple, but I'm using two columns to save space. Only way I can think to do it is to deselect all nodes from the adjacent treeview each time a node is selected? Any ideas on the best way to implement something like this?

Great product by the way. Simply awesome. The skins, performance, everything, is the best around.

Thanks,
Levi
