access RadGrid edit form control in javascript

Hi ,
i have a datagrid within an editform template . With the JavaScript function document.getElementById i can't access to form controls, may be because this id is generated automatically and is different for the id specified in a template .
There are ways to this access realization?

Thanks’ for reply

RadCompression and Chrome issue

A few weeks ago, I decided to try RadCompression on my website, and followed the instructions here. It seemed to work fine in FireFox (which I use for development), but when we finally got around to cross-browser testing, found that several pages started getting an exception in System.Web.UI.Page.RegisterRequiresControlState(), for example:




[InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Collections.IDictionary'.]
   System.Web.UI.Page.RegisterRequiresControlState(Control control) +104
   System.Web.UI.WebControls.PasswordRecovery.OnInit(EventArgs e) +32
   System.Web.UI.Control.InitRecursive(Control namingContainer) +333
   System.Web.UI.Control.InitRecursive(Control namingContainer) +210
   System.Web.UI.Control.AddedControl(Control control, Int32 index) +198
   System.Web.UI.ControlCollection.Add(Control child) +80
   System.Web.UI.WebControls.Login.CreateChildControls() +175
   System.Web.UI.Control.EnsureChildControls() +87
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +23
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Page.FindControl(String id) +38
   System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +232
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1743

In debugging the issue, I found that
1. It only seems to affect Chrome browser
2. Removing RadCompression stopped the error
3. Keeping RadCompression but changing the browser controlAdapter from RadSessionPageStateCompression to RadHiddenFieldPageStateCompression stopped the error

Is there any reason why this would happen only in Chrome? Is there something else I need to use RadSessionPageStateCompression?

Thanks for any info

[Edit: I'm using v2011.1.519.35]

Draging a DIV to the TreeView

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.

Checkbox CheckedChanged event in a template

Hello,

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" >

<Items>

<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.
