Hello,

What I will need is this. On the page I have one RadTreeView control, on the same page I can have HTML DIV element. Is it possible, somehow to drag this DIV element to the RadTreeView control and get server side event?

This is very similar, or even identical to functionality you have on FileExplorer / First Look example where you can drag table rows to the tree and move files by doing so.

Thanks!
Marko

onmenuitemclick event not firing when menu items loaded dynamically

I am trying to load Menu Items Dynamically in the preRender event based on user permissions.

if (_UserInfo.ProvPrivInd)

{

RibbonBarMenuItem rbmiAddProject = new RibbonBarMenuItem();

rbmiAddProject.Text = Resources.Hub.EntMgmt_Ribbon_ActionMenu_NewEntProj_Text;

rbmiAddProject.ImageUrl = "~/Images/Add-New-Folder.png";

rbmiAddProject.Font.Size = FontUnit.Small;

rbmiAddProject.Value = "NewEntProject";

rbmiAddProject.Enabled = true;

rbmEnterpriseActionMenu.Items.Add(rbmiAddProject);

}

if (!_UserInfo.ECAExecInd || _UserInfo.ECAAdminInd || _UserInfo.RRDAdminInd)

{

RibbonBarMenuItem rbmiAddUesr = new RibbonBarMenuItem();

rbmiAddUesr.Text = Resources.Hub.EntMgmt_Ribbon_ActionMenu_AddUsersMultiProj_Text;

rbmiAddUesr.ImageUrl = "~/Images/Change-Group.png";

rbmiAddUesr.Font.Size = FontUnit.Small;

rbmiAddUesr.Value = "AddUsersMultiProj";

rbmEnterpriseActionMenu.Items.Add(rbmiAddUesr);

RibbonBarMenuItem rbmiRemoveUesr = new RibbonBarMenuItem();

rbmiRemoveUesr.Text = Resources.Hub.EntMgmt_Ribbon_ActionMenu_RemUsersMultiProj_Text;

rbmiRemoveUesr.ImageUrl = "~/Images/Delete-User.png";

rbmiRemoveUesr.Font.Size = FontUnit.Small;

rbmiRemoveUesr.Value = "RemUsersMultiProj";

rbmEnterpriseActionMenu.Items.Add(rbmiRemoveUesr);

}

But when I click on the item in the browser a post back occurs but the onmenuitemclick event isn't handled.
I get a javascript error on the page.

I have a menu with an item template. Inside it there is a checkbox. I'd like to postback when the checkbox checked state is changed, but cant get it to work. Here is the code:

<telerik:RadMenu ID="RadMenu1" runat="server" EnableRoundedCorners="True" EnableShadows="True"

Skin="Office2007" >

<Items>

<telerik:RadMenuItem runat="server" Text="Profile" PostBack="False" >

<telerik:RadMenuItem runat="server" Text="Save current selections as default" Font-Size="12px">

</telerik:RadMenuItem>

<telerik:RadMenuItem runat="server" Text="Load default selections" Font-Size="12px">

</telerik:RadMenuItem>

<telerik:RadMenuItem runat="server" IsSeparator="True" Text="Child RadMenuItem 3" Font-Size="12px"

PostBack="False">

</telerik:RadMenuItem>

<telerik:RadMenuItem Text="AlwaysLoad" >

<ItemTemplate>

<asp:CheckBox ID="chkAlwaysLoad" runat="server" Text=" Always load default selections" Font-Size="11px" />

</ItemTemplate>

</telerik:RadMenuItem>

<telerik:RadMenuItem Text="AlwaysSave" >

<ItemTemplate>

<asp:CheckBox ID="chkAlwaysSave" runat="server" Text=" Always save current selections" Font-Size="11px" />

</ItemTemplate>

</telerik:RadMenuItem>

</Items>

</telerik:RadMenuItem>

</Items>

</telerik:RadMenu>

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

Dim alwaysSave As CheckBox = RadMenu1.FindItemByText("AlwaysSave").FindControl("chkAlwaysSave")

AddHandler alwaysSave.CheckedChanged, AddressOf alwaysSave_CheckedChanged

Protected Sub alwaysSave_CheckedChanged(sender As Object, e As System.EventArgs)

Profile.CreateProject.AlwaysSave = sender.Checked

End Sub

But the event is never fired. Can you please tell me what am I doing wrong?

Thank you very much.

[Solved] Expand a branch to one particular node

As part on the functionality I am trying to include in my web application, is the ability to “search” the TreeList. I have a field selector drop down list and a text box or check box to enter the search criteria. The search button performs a post back where I then location a match in the data source. Now that I have the matching record, how can I force it to be displayed selected? The result of the search may be a child node somewhere down the hierarchy not currently being displayed. If this is the case I would want the branch with the matching criteria to be expanded to this item. Then I would want to select the item. Does anyone have any ideas on how to force a node to be displayed?

I have not looked into using ExpandItemToLevel since it is liable to expose too many items. I don’t think it would work for one level at a time since I might be calling it for items not displayed, recursive calls.
