RadTreeView drag and drop RadWindow

[Arindam]

Hi

I am generating RadTreeView dynamically, please find the code snippet below:-

Telerik.Web.UI.RadTreeView ReportTree = new Telerik.Web.UI.RadTreeView();
ReportTree.ID = "rptTree" + i;
ReportTree.Height = 400;
ReportTree.Nodes.Clear();
ReportTree.Skin = "Telerik";
ReportTree.EnableDragAndDrop = true;

SqlCommand rscommand_Child = new SqlCommand(myquery, myconnection);
DataTable dtt = new DataTable();
SqlDataAdapter daa = new SqlDataAdapter(rscommand_Child);
daa.Fill(dtt);

for (int ii = 0; ii < dtt.Rows.Count; ii++)
{
Telerik.Web.UI.RadTreeNode tr = new Telerik.Web.UI.RadTreeNode();
tr.Text = "" + dtt.Rows[ii][1].ToString() + "";
ReportTree.Nodes.Add(tr);
}
ReportTree.OnClientNodeDragging = "openDashboards";

Somehow openDashboards in not executing. openDashboards code snippet:-

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function openDashboards(source, dest, e)
        {
                var oManager = GetRadWindowManager();
                //get the clicked node
                var Url = eventArgs.get_node(sender, eventArgs).get_value();
                window.alert("1");
                //get the active RadWindow
                var oWnd = GetRadWindowManager().getActiveWindow();
                //now we need to open a new RadWindow and ensure that
                //such RadWindow has not been already opened.
                var windows = oManager.get_windows();
                for (var i=0; i < windows.length; i++)
                   {
                       var wnd = windows[i];
                       //check if an already created window has that Url
                       if (wnd.get_navigateUrl() == Url)
                       {
                           //if so - activate that window
                           wnd.setActive(true);
                           return;
                       }
                   }
                //else open a new window
                radopen(Url,null);
        }
        </script>
    </telerik:RadCodeBlock>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" VisibleOnPageLoad="false"
                    VisibleTitlebar="true" VisibleStatusbar="false"
                     ReloadOnShow ="true" ShowContentDuringLoad="true" RestrictionZoneID="dropDiv" Skin="Telerik">
</telerik:RadWindowManager>

Can somebody help where I am going wrong?

Thanks!!!

Hi Arindam,

The openDashboards routine should be defined in the same page as the treeview. Please verify that this is the case.

Yes you are right:-

In MyDashboard.aspx page:-

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function openDashboards(source, dest, e)
        {
                var oManager = GetRadWindowManager();
                //get the clicked node
                var Url = eventArgs.get_node(sender, eventArgs).get_value();
                window.alert("1");
                //get the active RadWindow
                var oWnd = GetRadWindowManager().getActiveWindow();
                //now we need to open a new RadWindow and ensure that
                //such RadWindow has not been already opened.
                var windows = oManager.get_windows();
                for (var i=0; i < windows.length; i++)
                   {
                       var wnd = windows[i];
                       //check if an already created window has that Url
                       if (wnd.get_navigateUrl() == Url)
                       {
                           //if so - activate that window
                           wnd.setActive(true);
                           return;
                       }
                   }
                //else open a new window
                radopen(Url,null);
        }
        </script>
    </telerik:RadCodeBlock>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" VisibleOnPageLoad="false"
                    VisibleTitlebar="true" VisibleStatusbar="false"
                     ReloadOnShow ="true" ShowContentDuringLoad="true" RestrictionZoneID="dropDiv" Skin="Telerik">
</telerik:RadWindowManager>




In MyDashboard.aspx.cs page:-

Telerik.Web.UI.RadTreeView ReportTree = new Telerik.Web.UI.RadTreeView();
ReportTree.ID = "rptTree" + i;
ReportTree.Height = 400;
ReportTree.Nodes.Clear();
ReportTree.Skin = "Telerik";
ReportTree.EnableDragAndDrop = true;

SqlCommand rscommand_Child = new SqlCommand(myquery, myconnection);
DataTable dtt = new DataTable();
SqlDataAdapter daa = new SqlDataAdapter(rscommand_Child);
daa.Fill(dtt);

for (int ii = 0; ii < dtt.Rows.Count; ii++)
{
Telerik.Web.UI.RadTreeNode tr = new Telerik.Web.UI.RadTreeNode();
tr.Text = "" + dtt.Rows[ii][1].ToString() + "";
ReportTree.Nodes.Add(tr);
} ReportTree.OnClientNodeDragging = "openDashboards";

So are you telling the openDashboards should be in MyDashboard.aspx.cs, if yes then how can I do that?

Thanks!!!

Hello Arindam,

The declaration is ok now that you give more details. However the signature of the openDashboards method is wrong. It is declared as
function openDashboards(source, dest, e)
where it should be
function openDashboards(sender, eventArgs)


Additionally this code is wrong:

ar Url = eventArgs.get_node(sender, eventArgs).get_value();
It should be like this:

var url =eventArgs.get_node().get_value()

I suggest you check our online documentation for using the OnClientNodeDragging event.

Kind regards,
