RADChart - Error in using TempImagesFolder

Hi All,

I have a custom web part which includes RAD Chart control.
This web part is used in WSS 3.0.

There are following two methods available in RAD Chart to create chart's temp images.

1. Use Session
2. Use Folder

First method can not be used in my case because sessions are disabled in WSS 3.0 by default and I dont want to enable it.

So I used second method in my RAD Chart.

Please refer the following code for details:

*************************************************************************

// Create chart object.

RadChart radChartObj = new RadChart();

radChartObj.EnableViewState =

false;

radChartObj.UseSession =

false;

radChartObj.TempImagesFolder =

"~/_layouts/Documenta/Reports/TempFiles";

radChartObj.ID =

"radChart";

*************************************************************************

If I log in to my SharePoint site with the user who has 'Write' permissions on 'TempFiles' folder, then chart is created successfully.
But If I log in with user who does not have 'Write' permissions on 'TempFiles' folder, then RenderContents() function of web part throws exception.

Exception details:
A generic error occurred in GDI+. Check the folder specified in the TempImagesFolder property of the control. Current value is "/_layouts/Documenta/Reports/TempFiles". The folder should exist and must have been granted write permissions for the ASPNET user.
---------------------------------------------------------------

My web application's pool identity is Network Service.
I assigned 'Write' permissions on 'TempFiles' folder for Network Service and ASPNET user.
But behavior remains same. RenderContents() function throws an exception.

Please suggest a solution so that I don't need to assign 'Write' permission for each user of SharePoint site.

Please let me know if I can use SPSecurity.RunWithElevatedPrivileges in this case. It is just an idea. May be it is not valid in this case.

Please let me know your comments.
It is really urgent.

Thanking you in anticipation.

Rights issue on TempImagesFolder

Hi All,

I have a custom web part which includes RAD Chart control.
This web part is used in WSS 3.0.

To create chart's temp images, I am using temp folder created at path "~/_layouts/Documenta/Reports/TempFiles".

Please refer the following code for details:

*************************************************************************

// Create chart object.

RadChart radChartObj = new RadChart();

radChartObj.EnableViewState = false;

radChartObj.UseSession = false;

radChartObj.TempImagesFolder = "~/_layouts/Documenta/Reports/TempFiles";

radChartObj.ID = "radChart";

*************************************************************************

As per Telerik documentation, web application should have 'write' permissions to the temporary folder.
Please refer to the below link:
http://www.telerik.com/help/aspnet-ajax/advancedsession.html

My web application's pool identity is Network Service.
So, I assigned 'Write' permissions on 'TempFiles' folder for Network Service and ASPNET user.

If I log in to my SharePoint site with the user who has 'Write' permissions on 'TempFiles' folder, then chart is created successfully.
But If I log in with user who does not have 'Write' permissions on 'TempFiles' folder, then RenderContents() function of web part throws exception.

Exception details:
A generic error occurred in GDI+. Check the folder specified in the TempImagesFolder property of the control. Current value is "/_layouts/Documenta/Reports/TempFiles". The folder should exist and must have been granted write permissions for the ASPNET user.
---------------------------------------------------------------

Please suggest a solution so that I don't need to assign 'Write' permission for each user of SharePoint site.

Please let me know your comments.
It is really urgent.

Thanking you in anticipation.

Hello,

I'm using RadPanelBar and have defined some item in it (RadPanelItem). For these items I need to customize the band as follows:

1. Hide the default expaned/collapsed image (which is shown in the right side of the band). ?

2. I'm showing my own images for expaned / collapsed states as below, and also I want to set "uparrow.gif" as default image for the band ,how to set a default image for the band ?

<telerik:RadPanelItem Text="Employees" Value="emp" Expanded="true" ExpandedImageUrl="uparrow.gif" SelectedImageUrl="downarrow.gif">
<telerik:RadGrid ID="grdEmp" GridLines="None" runat="server" AllowAutomaticDeletes="True" EnableViewState="true"
AllowMultiRowSelection="true" AllowAutomaticInserts="True" AllowAutomaticUpdates="True"
AllowPaging="false" Skin="Telerik" AutoGenerateColumns="False" DataSourceID="emp"
>

3. in another case , i have a radgrid under the radpanelitem, and want to set the number of records of the grid to be displayed in the radpanelItem band on the right hand side , for example 14500 item(s)

Kindly suggest.

[Solved] Detect the trigger for row selection in OnRowSelecting event

How do I detect if the OnRowSelecting client side event was triggered by the GridClientSelectColumn checkbox or by clicking on the row (outside the checkbox)?

I found a few posts but they don't seem to apply to the new grid version.

Prevent FullRowSelect

Hi,

I have a grid with a GridClientSelectColumn, i had a problem of selecting the row when clicking anywhere on it (even a button with a different action <<file download in my case>>), so i had to hack this so that the row is selected only when the check box is clicked, the following code works:

<ClientEvents OnRowSelecting ="RowSelecting" />

    
            function RowSelecting(sender, eventArgs)   
        
                        {    
        
                          var e =  window.event;   
        
                          if(e.srcElement.tagName == "INPUT")   
        
                          {    
        
                            eventArgs.set_cancel(false); 
        
                          }   
        
                          else 
        
                          {   
        
                           eventArgs.set_cancel(true); 
        
                          }   
        
                        }

the problem i am having now is that window.event does not work on firefox,

any help?

RadGrid With GridClientSelectColumn

I have a RadGrid with a GridClientSelectColumn to allow the user to select several rows.
Unfortunately when the user clicks on a row(but not on the selectcolumn) all the selected rows are deselected and the row which is clicked on is selected,
How can I prevent this?(eg. only the GridClientSelectColumn should react to clicks the rest of the row should ignore them).

The second grid on this( http://demos.telerik.com/aspnet-ajax/grid/examples/client/selecting/defaultcs.aspx ) example page has the same "error"
