We upgraded to the newest release version of the RadControls today. When we did that, we noticed that our pages started to hit the Page_Load function multiple times for each request. We created a small Telerik Web Application and found that the RibbonBarGroup in the RibbonBar control is causing the issue.

We used Visual Studio 2010 and created a Telerik Web Application project in VB. We have a master page, an aspx page and a vb code behind for each.

RibbonBar.Master

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadRibbonBar ID="RadRibbonBar1" runat="server">

<telerik:RibbonBarTab Text="Tab 1">

<telerik:RibbonBarGroup Text="Group 1">

<Items>

<telerik:RibbonBarButton ID="rbb1" runat="server" Text="Button 1" />

</Items>

</telerik:RibbonBarGroup>

</telerik:RibbonBarTab>

</telerik:RadRibbonBar>

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

</asp:ContentPlaceHolder>

RibbonBar.Master.vb

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

If Me.Page.IsPostBack Then

Response.Write(DateTime.Now & "-RibbonBar.Master Not IsPostBack<br />")

Else

Response.Write(DateTime.Now & "-RibbonBar.Master IsPostBack<br />")

End If

End Sub

RibbonBar.aspx (Using the RibbonBar.Master)

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<telerik:RadButton ID="btnRibbonBar" runat="server" Text="RadButton">

</telerik:RadButton>

</asp:Content>

RibbonBar.aspx.vb

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

If Me.Page.IsPostBack Then

Response.Write(DateTime.Now & "-RibbonBar.aspx Not IsPostBack<br />")

Else

Response.Write(DateTime.Now & "-RibbonBar.aspx IsPostBack<br />")

End If

End Sub

Private Sub btnRibbonBar_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnRibbonBar.Click

Response.Write(DateTime.Now & "-btnRibbonBar_Click<br />")

End Sub

If you put a break point on each of the subs, you will see that when you click the button, the Page_Load events in the aspx and master page are hit, then the click event for the button, then the Page_Load events in the aspx and master page are hit again.

Thanks for your time,

RadEditor removes href attribute on copy paste- Firefox issue

Hi Support,

I'm using latest version of "Telerik RadControls for ASP.NET Ajax" (version :2011.1.413.35).

I have a text along with the image used as a hyperlink as follows.

"Sample Text.<a href="javascript:myfunction()"><img title="sample image" src="sample.gif" /></a>"

When i copy the above text and paste it inside editor, the editor removes the href attribute of 'anchor' tag. It happens only with firefox and safari. It is working correctly in internet explorer.

"Sample Text.<a ><img title="sample image" src="sample.gif" /></a>"

Is there any solution for this.? Awaiting for sooner response

Where do I find the default contents of EditorContentArea.css?

I've been searching for 2 days now to find a template to work off of and every post and article brings my back to the same KB. I've added this:

<telerik:RadEditor runat="server" ID="RadEditor1">

<CssFiles>

<telerik:EditorCssFile Value="~/Editor/EditorContentArea.css" />

</CssFiles>

</telerik:RadEditor>

Now where do I find a copy of the original EditorContentArea.css to work off of? The article references Getting the CSS from the Telerik.Web.UI.dll... how do I do this? I work within a multi-developer environment and do not have the radcontrols installed directly on my machine, but as part of the solution I work within.

How do I get the contents of this file?

RadTabStrip Validation

In my application, I'm using a RadTabStrip and a validation control to validate user input, but when I switch tabs, and then click on a button, the first postback is ignored, but if I click twice it will postback.

Any ideas?
Thanks,

TabStrip

RadList ItemTemplate unable to get at the Eval values.

I am unable to retrieve the values for list box items when I am using the template column when in a different event such as a button click.
I need to get at the values for the selected item.

my ascx does this
                    <telerik:RadListBox ID="UserLst" runat="server" Width="320px" Height="400px" AutoPostBack="True"
                        Skin="Windows7">
                        <ItemTemplate>
                            <div class="radlist-itemdiv">
                                <div class="radlist-imagediv">
                                    <img src='Images/icon_human.png' alt="User Image" />
                                </div>
                                <div class="radlist-textdiv">
                                    <span class="radlist-title"><span class="radlist-column">Access Rights</span><%#Eval("AccessLevel")%></span><br /><span class="radlist-title"><span class="radlist-column">Full Name</span><%#Eval("Fullname")%></span><br /><span class="radlist-title"><span class="radlist-column">User Ref No.</span><%#Eval("UIDRef")%></span></div>
                            </div>
                        </ItemTemplate>
                    </telerik:RadListBox>

in my .CS Code file I am doing this in page_load
UserLst.DataSource = WS.GetUserList(); // returns a dataset
UserLst.DataBind();

in my .cs file I have wired an imagebuttonclick event using radajaxpanel.

        protected void EditUserClick(object sender, ImageClickEventArgs e)
        {
            string UIDRef = xxx; // get the UIDRef that is in the selecteditem        ????????
        }

This last buttonclick routine is where I am strugling to get at the UIDRef that is part of the selected item?
Once I have the UIDRef i can locate the full record and start to edit it.

Any help greatly appreciated, Thanks.

Can I add a radGrid to a nestedViewTemplate

I am currently making a 3-tier Hierarchy using rad grids, however for some reason the last rad grid in the hierarchy is not being recognized by Visual studio 2008 (i.e. it is not being added to the designer class).

<telerik:RadMultiPage runat="server" ID="RadMultiPage1" SelectedIndex="0" RenderSelectedPageOnly="false">
<telerik:RadPageView ID="RadPageView1" runat="server">
    <telerik:RadGrid ID="radGrd1">
        <MasterTableView>
            <DetailTables>
                <telerik:GridTableView>
                    <NestedViewTemplate>
                        <telerik:RadMultiPage>
                            <telerik:RadPageView>
                                <%--add Radgrid Here--%>
                            </telerik:RadPageView>
                        </telerik:RadMultiPage>
                    </NestedViewTemplate>
                </telerik:GridTableView>
            </DetailTables>
        </MasterTableView>
    </telerik:RadGrid>
</telerik:RadPageView>

Here is a skeleton of the code i am using.

Is it possible to add a rad grid in that position? If so why is it that visual studio is not adding this code to the designer class and thus making it inaccessible in the code behind file?

I have tried adding the control manually myself, although it appears in the intellisense the control itself is set to null during runtime thus making it impossible to bind any data to the Grid.

Please Help
