Configuring Pie Chart to show multiple items in legend

Alright, I'm trying to create a pie chart that shows Locations in the Legend so that each location as a designated color, and the values assigned to each location is TotalSales. I thought it would be an easy thing to implement, but I'm running into issues.

When I implement the code below, it shows the TotalSales all around the pie chart (I know that's because of LabelLocation="Auto") but the legend on the right would just say "Series xx". I know how to get the name to change, but I don't know how to get it to create a new item for each location.

Can someone help me out with this?

Here's my code:

<telerik:RadChart ID="radSales" AutoLayout="true" runat="Server" Width="900px" Skin="Web20"

Style="margin: 0px auto;">

<Legend Visible="true">

<Appearance GroupNameFormat="#VALUE">

</Appearance>

</Legend>

<ChartTitle TextBlock-Text="Total Sales">

<TextBlock>

<Appearance TextProperties-Font="Verdana, 20px, style=Bold" TextProperties-Color="#00529B">

</Appearance>

</TextBlock>

</ChartTitle>

<PlotArea>

<Appearance Dimensions-Margins="18%, 22%, 12%, 14%">

</Appearance>

<XAxis DataLabelsColumn="Location">

<Appearance>

<TextAppearance TextProperties-Font="Verdana, 8pt, style=Bold">

</TextAppearance>

</Appearance>

</XAxis>

</PlotArea>

<Series>

<telerik:ChartSeries DataXColumn="Location" DataYColumn="TotalSales" DefaultLabelValue="#Y{C}"

Type="Pie">

<Appearance>

<LabelAppearance LabelLocation="Auto">

</LabelAppearance>

<TextAppearance TextProperties-Font="Verdana, 11pt, style=Bold" TextProperties-Color="#00529B">

</TextAppearance>

</Appearance>

</telerik:ChartSeries>

</Series>

</telerik:RadChart>

[Solved] Find control inside window from parent window

Hello,
I have a page, which opens a dialog window (Window1). In Window1 there's a custom AJAX control with button which in turn opens new dialog window (Window2). When Window2 closes, a page must handle Window2's OnClientClose event, and Window2 must pass some data to my custom control on WIndow1. To avoid stack overflow, as you adviced here, I put handler on main page.
And now I want to get data sent by Window2 and put them to my control on Window1. This is how I'm doing that now:

 function referenceWindowClose(sender, args) {
            sender.remove_close(referenceWindowClose);
            var arg = args.get_argument();
            if (!arg) return;
            var ctl = $find(arg.TargetControlID);
            if (ctl == null) return;
            ctl.set_text(arg.Caption);
            ctl.set_value(arg.RefID);
        }

Variable named ctl is my custom AJAX control. Problem is ctl is always null. I know this happens because Window1 is in IFRAME. But how do I find it from main page? Using sender parameter? Please help.

[Solved] Drag & Drop Images

Hello,

I'm looking for code to drag and drop an image from a listbox to another listbox or another solution to achieve this functionality. The usecase is that a user can select from a list of images and drag & drop one or more images to another "placeholder". The next step is that I can save the dropped images to a database of filesystem. Can anyone point me to some examples or solution?

Thanks in advance

Disabling Flash/Silverlight (for testing)

I have a RadAsyncUpload control on my page and I want to test all of my functionality for those clients that can't/don't have either Flash or Silverlight installed.

Using code found in this forum I have this in my markup just before the definition of the AsyncUpload control ...

<para xmlns="http://ddue.schemas.microsoft.com/authoring/2003/5">

<script type="text/javascript">

Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () { return false; }

</script>

</para>

Now, when testing, I was expecting to:

Not be able to select multiple file
See an Add button to add a new file

So, I'm doing something wrong, it's broken or my expectations are wrong.

Which is it?

RadGrid - Order of Parameters in DS Random

So I'm using the grid to manage a number of reference tables. Most just have the identity and a text field, one has several text fields. I'm doing it as generically as possible, with one grid and one SQLDataSource on the page, and 4 stored procs with generic parameters for insert, update, delete and select. I have corresponding params for each action defined declaratively in the datasource.

<SelectParameters>

<asp:Parameter Name="itemType" Type="String" />

</SelectParameters>

<InsertParameters>

<asp:Parameter Name="itemType" Type="String" />

<asp:Parameter Name="itemValue" Type="String" />

<asp:Parameter Name="itemValue2" Type="String" />

<asp:Parameter Name="itemValue3" Type="String" />

</InsertParameters>

<DeleteParameters>

<asp:Parameter Name="itemID" Type="Int32" />

<asp:Parameter Name="itemType" Type="String" />

</DeleteParameters>

<UpdateParameters>

<asp:Parameter Name="itemID" Type="Int32" />

<asp:Parameter Name="itemType" Type="String" />

<asp:Parameter Name="itemValue" Type="String" />

<asp:Parameter Name="itemValue2" Type="String" />

<asp:Parameter Name="itemValue3" Type="String" />

</UpdateParameters>

I'm handling the Updating, Selecting etc... events for the datasource, and set the value of the datasource params there before it runs each command.

protected void dsActivity_Deleting(object sender, SqlDataSourceCommandEventArgs e)

{

int paramcount = e.Command.Parameters.Count;

e.Command.Parameters["@itemID"].Value = e.Command.Parameters["@" + lstReference.Items[lstReference.SelectedIndex].Value + "ID"].Value.ToString();

e.Command.Parameters["@itemType"].Value = lstReference.Items[lstReference.SelectedIndex].Value;

while (e.Command.Parameters.Count > 2)

e.Command.Parameters.RemoveAt(e.Command.Parameters.Count - 1);

}

The problem I had to work around was that although the grid appends the field values to the params in the datasource events, the order of them is not consistent. So that makes it hard to handle them in a generic manner since I can't use the index to reference them, not knowing what param might be in a given position.

I've worked around this since I ran into it, but it would have been a lot cleaner if I could depend on the parameters to be added in the same order. This would be handy for certain scenarios like this if it would build that with the params in the corresponding order they were originally retrieved.

RadGrid Export - RadCompression.Compress issue

Hi,

I have a radgrid with some smileys which had been inserted from radEditor.
Now when I export the grid to word, it exports it well but throws the below bug:

Error Info:Object reference not set to an instance of an object.
Error URL path:http://www.xtz.com/Smiley/haha.gif
Stack trace: at Telerik.Web.UI.RadCompression.Compress(HttpApplication application) at Telerik.Web.UI.RadCompression.PreRequestHandlerExecute(Object sender, EventArgs e) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

The Smiley's path is correct, and I am able to see the image on loading the URL path.
But why I get the RadCompression bug?
