[Solved] IE 7 Toolbar Missing

I have a page where there are multiple editors on the screen, on the initial load only one editor is visible to the user and using javascript the divs style are changed from display: none to display: block in IE 7 when the editor is initially hidden and then told to display the toolbar is missing. Works in FF/Chrome/IE 8

Is there a way to have the toolbar show up for IE 7 in this instance:

                    <html xmlns="http://www.w3.org/1999/xhtml">

radticker xml problem

Hello ,

I'm using radticker in my form in that I need to take data from xml file but I'm getting error, FOA I'm using following XML code

<test>
  <test Heading="Heading One" Body="This is Body"/>
  <test Heading="Heasing two" Body="This is body two."/>
</test>

below is what I'm using in aspx code

    <telerik:RadRotator ID="RadRotator1" runat="server" ScrollDirection="Left" ScrollDuration="7000" DataSourceID="XmlDataSource1" RenderingCompatibility="3.5" Skin="Windows7">
    <ItemTemplate>
        <telerik:RadTicker ID="RadTicker1" runat="server" AutoStart="true" LineDuration="4000" Loop="true">
        <Items>
            <telerik:RadTickerItem Text='<%# XPath("Heading") %>'>
            </telerik:RadTickerItem>
            <telerik:RadTickerItem Text='<%# XPath("Body") %>'>
            </telerik:RadTickerItem>
        </Items>
    </telerik:RadTicker>
    </ItemTemplate>
    </telerik:RadRotator>
    <asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="~/XMLFile.xml">
    </asp:XmlDataSource>

After running this I don't get any output in browser, but if I put simple text instead of xpath.... it appears in browser tickering & rotating but not if I choose from xml file

In above code what I need to do is that firstly heading1 and body1 should ticker in first rotation and heading2 and body2 should ticker in second rotation

If anyone could provide solution for this that would be great for me I tried for this a lot but with no success till now

Plz reply

Thanks

TreeView with Ajax EnableHistory="True" doesn't work in IE

IE cannot resolve the URL for a server side callback when collapsing a node if the URL contains a hash symbol (#).

Since the page ScriptManager tracks history points by appending a hash code to the page URL, the treeview will fail to load when using ajax history (back button support). I have the same issue as well with RadScriptManager.

Works correctly in Firefox. Using release 2009.3.1314.35.

'Drawing' hierarchy grid in usercontrol

Hello,
I am working with a usercontrol to add/edit items in a RadGrid row

    
                            <EditFormSettings UserControlName="EmployeeDetails.ascx" EditFormType="WebUserControl">  
        
                                <EditColumn UniqueName="EditCommandColumn1">  
        
                                </EditColumn> 
        
                            </EditFormSettings>

But each item/row can have associated another table in which I would like to be able to insert/edit so what i should see at the usercontrol is like another radgrid control. I have read in the live examples that this can be done with hierarchy and DetailTable, but I don´t know how to 'draw' this table in the usercontrol so the items are binded to the employee detail showed in the usercontrol.

This is my UserControl

    
            <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="EmployeeDetails.ascx.cs" Inherits="telerik_webGrid.EmployeeDetails" %>

Showfooter of a DetailsTableView dynamically

Hi,

I want to be able to show the footer of a RadGrid's detailstableview dynamically and populate a RadComboBox on a button click event.

    
            protected void Button_Click(object sender, EventArgs e) 
        
            { 
        
                GridTableView tblView = (GridTableView)(sender as LinkButton).Parent.Parent.Parent.Parent.Parent; 
        
                tblView.ShowFooter = true;

                GridItem item = tblView.GetItems[GridItemType.Footer)[0];

                RadComboBox radCombo = (RadComboBox)item.FindControl("RadCombo1");

                DataTable dt = GetDataSource();

                radCombo.DataSource = dt;

                radCombo.DataBind();

                 tblView.Rebind(); <-solution

            }

So my problem is the footer of a RadGrid's detailstableview will not display until I collapse and then re expand the parent node. How can this all be done smoothly, to just show the footer on a button click event.

Thanks,

Bill

Unable to add/edit child elements in Self Referencing Hierarchy

Hey everyone, I have a self referencing hierarchy and I am unable to configure it properly to allow editing or adding records to child nodes. If it is a top level parent both functions work perfecting. However, clicking on either the add or edit command links causes the entire child node to close and disappear. Clicking refresh on another node (but not the master table) cause the rows to reappear, including the edit/add row, but the content of those rows are empty.

I came across this post and followed it's instructions to no avail. It does not seem correct for self referencing hierarchies anyways. The relevant code from my project is below. Thanks in advance!

column resize questions

I have a few questions about resizing columns in a radGrid.

1. When I have EnableRealTimeResize=true set on my grid, a pop up appears saying the width in pixels of the column when it is being resized. Ideally, I'd like to show this width as a % rather than a pixel width....is this possible? If not, can I suppress this pop up?

2. I need to change data in the grid when a column is resized.....what is the best way to go about this? I don't see a server event that helps me.

Thanks!
