RadEditor ImageManager - View Different Site Collection

Hello,

I'm wondering if there have been any changes to the SharePoint RadEditor that enables the ImageManager to view libraries across different site collections? It appears that setting an ImagesPaths to anything outside of the current site collection doesn't work.

This would be extremely useful because we're using the RadEditor to edit content from an administration site collection (requires authentication) that ultimately needs to be displayed on a public site collection (no authentication). To make this work, the images obviously must reside on the public site collection.

The MOSSImageManager allows you to manually type the path to an alternate site collection in the path input box. However, this image manager is far inferior to the Telerik one. Is there any reason why the Telerik one couldn't easily provide an option for this? SharePoint permissions would still govern accessibility of course, so the individual would need to have permissions to access those other site collections.

Thank you,

Chris

Hyperlinks not retained on postback

Hi Telerik Team

I have a RadGrid which is fetching data from a DataTable and uses OnNeedDataSource event for databinding. The columns are generated dynamically at runtime based on data from DataTable.
One of the columns of the RadGrid requires a hyperlink to the text displayed. I achieved this in ItemDataBound event where in I added a Hyperlink control to the cell.
This works fine.
But when the page postback occurs due to a change in server-side drop-down outside the Telerik RadGrid, the hyperlinks are not retained.
After page postback occurs, the hyperlinks are gone and data is displayed as plain text instead of hyperlinks.

One of the resolutions I tried is to ReBind() the RadGrid in PreRender event. But after doing that, Export To Excel functionality gives a problem. It gives excel file with an extra cell wherein where in I get custom-added URLS and images which is not expected. I also added IgnorePaging=true and ExportOnlyData=true for the same.

Please provide a resolution for the issue of retaining hyperlinks without affecting the functionality of Export to Excel.

Difficulty formatting the chart appearance.

I've not used the charting controls before and have been playing with them today as it looks like we'll need to start using them soon.

All I want to do is display the chart minus any of the titles and legends etc and am having trouble getting the ASP.Net version of the control to sit nicely in the border of the chart, but this seemed fairly easy to do in the WinForms control simply by hiding the legend and the chart title. I tried this in the ASP.Net version but it doesn;t appear to work.

I've attached a couple of images to show what I mean. I would like my chart to appear like the Winforms image below (note the uniform padding/margin around the chart) in my ASP.Net pages, but as you can see, this uniform spacing is lacking in the ASP.Net control.

I've also attached my code so you can see how I have generated the ASP.Net charts and hopefully someone will show me how to correctly set the appearance of my ASP.Net chart.

Thanks.

<telerik:RadChart ID="TestRadChart" runat="server" Width="465px" Height="200px"

Legend-Visible="False" ChartTitle-Visible="False" DefaultType="Line"

Skin="Default" >

</telerik:RadChart>

protected void Page_Load(object sender, EventArgs e)

{

Random random = new Random((int)DateTime.Now.Ticks);

int testValue;

ChartSeriesItem seriesItem;

ChartSeriesItemsCollection series1Items = new ChartSeriesItemsCollection();

ChartSeriesItemsCollection series2Items = new ChartSeriesItemsCollection();

for (int i = 0; i < 20; i++)

{

testValue = random.Next(0, 10);

seriesItem = new ChartSeriesItem(testValue, (i+1).ToString());

series1Items.Add(seriesItem);

}

for (int i = 0; i < 20; i++)

{

testValue = random.Next(0, 10);

seriesItem = new ChartSeriesItem(testValue, (i + 1).ToString());

series2Items.Add(seriesItem);

}

ChartSeries chartSeries1 = new ChartSeries();

chartSeries1.Items.AddRange(series1Items);

chartSeries1.Appearance.TextAppearance.Visible = false;

chartSeries1.Type = ChartSeriesType.Line;

chartSeries1.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.Nothing;

ChartSeries chartSeries2 = new ChartSeries();

chartSeries2.Items.AddRange(series2Items);

chartSeries2.Appearance.TextAppearance.Visible = false;

chartSeries2.Type = ChartSeriesType.Line;

chartSeries2.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.Nothing;

TestRadChart.Series.Add(chartSeries1);

TestRadChart.Series.Add(chartSeries2);

TestRadChart.Legend.Visible = false;

}

RadPanelItem: Adding controls to ItemTemplate programatically

I have the scenario below:

    
             ...... inside a RadPanelBar
        
                            <telerik:RadPanelItem Value="SubLocations" Text="Sub Locations" Expanded="true" CssClass="subPanel">  
        
                                <ItemTemplate> 
        
                                </ItemTemplate> 
        
                            </telerik:RadPanelItem>

I want to fill the content of ItemTemplate with a User Control which is decided at runtime. e.g. programatically.

I have tried creating a class derived from ITemplate. e.g. MyTemplateClass. I have overriden the InstantiateIn sub and added my control

    
                Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements System.Web.UI.ITemplate.InstantiateIn  
        
                    Dim locationsTree As SystemExplorerLocationsTree = _  
        
                            DirectCast(m_Page.LoadControl("~/IpscObject/GUI/SystemExplorer/SystemExplorerLocationsTree.ascx"), SystemExplorerLocationsTree)  
        
                    container.Controls.Add(locationsTree)  
        
                End Sub

On the aspx's Page_Init handler. I set RadPanelBar.ItemTemplate to a new instance of MyTemplateClass

    
            locationsPanel.ItemTemplate = new MyTemplateClass()

However, the InstantiateIn function is not called. What am I doing wrong?

Thanks,
Martin

Rotator Image Folder

Hi.

I have some folders in my solution such as UserAccount, Admin, etc.
I bind rotator to XmlDataSource, but when I'm not in site root (ex: MySiteName/Admin/Default.aspx) rotator does not work.
Here is the code:

<telerik:RadRotator ID="RadRotator1" runat="server" Height="150px"

ItemHeight="150px" ItemWidth="600px" ScrollDirection="Up" ScrollDuration="4000"

Width="600px" DataSourceID="XmlDataSource1">

<ItemTemplate>

<div>

<a href="<%# XPath("href") %>">

<img src="IMG/<%# XPath("filename") %>" alt="IMG/<%# XPath("filename") %>" style="border: 0px;"/>

</a>

</div>

</ItemTemplate>

</telerik:RadRotator>

</div>

<asp:XmlDataSource ID="XmlDataSource1" runat="server"

DataFile="~/Banners.xml" ></asp:XmlDataSource>

cascading dropdown list in grid

Hi,

I have a grid which use popup edit mode and set the popup at the center of the screen(http://www.telerik.com/help/aspnet-ajax/grid-center-popup-edit-form.html). Inside the grid, I also included a cascading dropdown in the edit form with ajax postback.

The problem that I am facing now is as below
1) I open edit form and the popup edit form open at the center of the screen as expected.
2) I manually align it to the right of the screen.
3) Then I selected cascading drop down list and the edit popup screen went back to center again.

How can prevent from going back to center once I align to other area?

Thanks
