Telerik Chart and SharePoint 2010 and getting red X image

Hi,

I have read your threads and have followed the direction in regards to getting the Telerik Chart to render in a SharePoint 2010 Web Part. Quick question, if there is no data in the Chart it should display right?

Here is what I have done so far.

1. Added the chart to a SharePoint visual web part
2. Added the following safe controls to the web.config.
          <SafeControl Assembly="Telerik.Web.UI, Version=2011.2.712.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI" TypeName="*" Safe="True" SafeAgainstScript="False" />
          <SafeControl Assembly="Telerik.Web.UI, Version=2011.2.712.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Charting" TypeName="*" Safe="True" SafeAgainstScript="False" />
3. Added the following httphandler to the <system.web><httpHandlers>
          <add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2011.2.712.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />
4. Set the UseSession to false as well as set the TempImagesFolder

<telerik:RadChart ID="RadChart1" runat="server"

TempImagesFolder="~/_Layouts/TelericChartsTemp" UseSession="False"

DataSourceID="XmlDataSource1">

5. Gave write permission to the application pool account to the /_Layouts/TelericChartsTemp folder
6. Deployed the solution but see the web part with a red X
7. I have also validated that the images are being copied to the /_Layouts/TelericChartsTemp folder

I am obviously missing something that is simple. Please help.

Regards,

Maui

Optimize RadGrid output (visualization)

Hi,
how to "configure" RadGrid for having column width always set to max nexessary width for showing a value/text complete? If header text is longer than any value in normal rows than column width should be set to that value and if a value in normal rows is having longest text/value than column width should be set to that rows necessary width for showing that value complete. No unnecessary whitespace is wanted.

Rgds,
Jesper

I want to change an uploaded filename if it already exist

In fileexplorer there is the abilty to upload files. Right now if I upload a file that has the same name as an existing file I get a prompt that tells me the file already exist. What I want to do is give the newfile a unique name and save it. For example I upload file named "Fred.txt" if "Fred.txt" already exist I will try "Fred-01.txt, Fred-02.txt, Fred-03.txt..." until I find one that doesnt exist then save the file with that name. How?

<telerik:RadFileExplorer ID="RadFileExplorer1" runat="server" OnClientItemSelected="OnImageSelected" EnableCopy="true" EnableAsyncUpload="true" >

</telerik:RadFileExplorer>

RadListBox not setting multiple values

Hi,

I am using RadListBox in one of our page, I can able to retrieve multiple selection info and save it to destination place, and when users open the form again, I need to get previous selections(multiple values) and set it to RadListBox, it only showing last value not other selection. I am calling the following method for setting values.

private

void setRadListBoxSelection(Telerik.Web.UI.RadListBox ctl, string val)

{

string[] selArr = val.Split('@');

foreach (string word in selArr)

{

ctl.SelectedValue = word;

// ctl.SelectedItem.Value = word;

}

}

do you have any suggestions for fixing the above issue.
