Hi,

I have two pages. Details and orderdetails. In Details page i have radwindow with window manager. I am opening orderdetails page using iframe in details page. See code below.

<telerik:RadWindowManager ID="RadWinManager" runat="server" OnClientDragStart="WindowDragStart"

OnClientResize="WindowDragStart" OnClientResizeStart="WindowDragStart" OnClientResizeEnd="WindowDragStart">

<Windows>

<telerik:RadWindow ID="DetailRadWind" runat="server" ShowContentDuringLoad="false"

BackColor="Green" Behaviors="Default" Animation="FlyIn" Skin="Forest">

<contenttemplate>

<div>

<iframe frameborder="0" style="width: 100%; height: 100%; border-style: none; border-width: 0px"

id="ifrmRadWin" runat="server"></iframe>

</div>

</contenttemplate>

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

ScriptManager.RegisterClientScriptBlock(this.up, this.GetType(), "strSearSiteName", "document.getElementById('ctl00_PagePlaceholder_DetailRadWind_C_ifrmRadWin').src='OrdDet.aspx'", true);

LinkButton lnkSiteName = (LinkButton)rw.FindControl("lnkSiteName");

string Title = "Order Details : " + lnkSiteName.Text;

ScriptManager.RegisterClientScriptBlock(this.up, this.GetType(), "BlkRejection", "OpenSiteWindow('" + Title + "')", true);

function OpenSiteWindow(Title) {

var WinTitle = Title;

var oWnd = GetRadWindowManager().GetWindowByName("DetailRadWind");

oWnd.set_width(810);

oWnd.set_height(580);

oWnd.set_title(WinTitle);

var radwind = window.radopen("", "DetailRadWind");

}

once i clikc the button in details page radwindow will open and displays the data in orderdetails page. And i have another radwindow in orderdetails page.(this window is in orderdetails page). once the popup comes up i have reject button in it. and if i click the reject button anthoer window will open. Now the problem is How to open the window that is orderdetails page. i tried to do it on visibleonpageload = true. but its loading on every pageload. How to open this window using javascript.

Here is orderdetails Page

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="smOrddet" runat="server">

</asp:ScriptManager>

<asp:UpdatePanel ID="upOrdTsk" runat="server">

<ContentTemplate>

<div>

Some HTML Code HERE</div>

<telerik:RadWindow ID="RadWinReject" runat="server" Height="340px" Width="515px"

Title="Bulk Task Completion" Behaviors="Default" CustomCSS="CSS/CustomStyle.css"

ShowContentDuringLoad="false" BackColor="Green" Animation="FlyIn" Skin="Forest">

<contenttemplate>

<asp:UpdatePanel ID="uprej" runat="server" OnUnload="Registerpanel5">

<ContentTemplate>

<div>Some HTML HERE</div>

</ContentTemplate>

</asp:UpdatePanel>

</contenttemplate>

</telerik:RadWindow>

</ContentTemplate>

</asp:UpdatePanel>

</form>

</body>

i tried this way but getting error like "oBrowserWnd" is null

in code behind

ScriptManager.RegisterClientScriptBlock(this.upOrdTsk, this.GetType(), "strSearCkts", "OpenPopUp()", true);

in javascript

function OpenPopUp() {

var oBrowserWnd = GetRadWindow().BrowserWindow;

oBrowserWnd.radopen("", "RadWinReject");

}

function GetRadWindow() {

var oWindow = null;

if (window.radWindow)

oWindow = window.radWindow;

else if (window.frameElement.radWindow)

oWindow = window.frameElement.radWindow;

return oWindow;

}

Hi Raj,

I am not sure that I understand your scenario completely, but in general, if a RadWindow declared in a RadWindowManager is showing up on every postback, you need to set the manager's EnableViewState property to false.
As for opening with JavaScript, if you want to open the window that is in the topmost page, you could use top.radopen(...) where top refers to the topmost (i.e. the one opened directly in the browser) page.

I hope this helps. If you still experience problems, please open a support ticket and send a sample project that will give us a better view over your exact setup and logic.

P.S. I noticed that you use a content template with an IFRAME in it. If you want to load an external page in RadWindow, you only need to set its NavigateUrl property - there is no need to use content template for that purpose.

Hello Raj,

I see that Fiko already answered your support ticket. For convenience I am pasting his reply below:

Hello Raj,

The problem was caused by these setups in your page:

The RadWindow was wrapped in an UpdatePanel. Please note that if you wrap the window in update panel, then it will be closed every time a postback occurs inside the wrapper UpdatePanel
In .NET35 if you disable the ViewState of a control, then this will be applied to its child controls. in your scenario, the RadWindow is a parent for all controls inside its ItemTemplate and this is why they inherit its EnableViewState="false" setting. This cause the DropDownList controls.

The solution in your case is to exude the RadWindow control from the partially updated requisition and set its EnableViewState="true" property (it is true by default). As alternative to the last suggestion you can update your project to .NET40, so you can specify the EnableViewState property for every control independently.
For your convenience I have attached the modified version of your project.

In addition, I believe that the information provided in this KB article will be of help for you.

Sincerely yours,
Georgi Tunev

Hi Georgi Tunev,

Atlast i made it work. It is working fine without any page refreshing.... But i have one more problem. I am binding the data to the dropdownlist in code behind. Here is code...

try

{

clsTaskUpdates_BL objBL = new clsTaskUpdates_BL();

DataSet dsResTasks = objBL.getRejectTasks_BL(Convert.ToInt32(Session["TaskID"]), Convert.ToInt32(Session["selorderID"]));

ddlRejTask.DataSource = dsResTasks.Tables[0];

ddlRejTask.DataTextField = "tskName";

ddlRejTask.DataValueField = "qid";

ddlRejTask.DataBind();

ddlRejTask.Items.Insert(0, "");

ddlRejTskReason.DataSource = dsResTasks.Tables[1];

ddlRejTskReason.DataTextField = "tskRejectReason";

ddlRejTskReason.DataValueField = "trrid";

ddlRejTskReason.DataBind();

ddlRejTskReason.Items.Insert(0, "");

Session["RejRootCause"] = dsResTasks.Tables[2];

ddlRejTskRootCause.Attributes.Add("onclick", "javascript:return ddlRejRea()");

Session["factionType"] = "2";

btnRejTsk.Text = "Reject Task";

ScriptManager.RegisterClientScriptBlock(this.upOrdTsk, this.GetType(), "strSearCkts", "OpenPopUp()", true);

}

catch (Exception ex)

{

}

My issue is if i use radwindow manager "ddlRejTask.Items.Insert(0, "");" is not working. (Please see image) But if i remove radwindowmanager its adding the initial item. I think radwindowmanager blocking that item. How to achieve this with radwindowmanager. I put enableviewstate = true in the page directive, in dropdownlist, in radwindow and radwindowmanager. But nothing works. Can you help me how to fix this....

here is my aspx code.....
