Problem exporting radgrid(promiteus) to PDF

[Mira Vaig]

 

On Main.aspx i have a grid with templateColumn

that contains image populated with another page (ImageUrl="LoadPicture.aspx?Indx=2).

My Main.aspx and LoadPicture.aspx – are in the same folder ("FolderName").

When I try to export to pdf , I get error :

hi,
sorry , i don't see in this article explanation  how to resolve my problem.
i repeat :
the problem is with virtual path of image in GridTemplateColunm.
my GridTemplateColumn contains Image with ImageUrl="LoadPicture.aspx?Indx=2".
the error message :
System.Web.HttpException: '/ProjectName/FolderName/LoadPicture.aspx?Indx=2' is not a valid virtual path.

Hi


You can use only virtual path

Here is an example:

            <rad:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource">
                <MasterTableView>
                    <Columns>
                        <rad:GridTemplateColumn UniqueName="MyGridTemplateColumn">
                            <ItemTemplate>
                                <asp:Image ID="Image1" runat="server" ImageUrl="~/Image.gif" />
                            </ItemTemplate>
                        </rad:GridTemplateColumn>
                    </Columns>
                </MasterTableView>
            </rad:RadGrid>

Hi,
I dont see how  solve the problem that occurs in export
of RadGrid (Prometeus) to  PDF in case :
                 grid has GridTemplateColumn that contains Image  with     ImageUrl="LoadPicture.aspx?Indx=2".
The problem occurs only when i have parameter.
If  ImageUrl="LoadPicture.aspx" - export works.

the error message :
System.Web.HttpException: '/ProjectName/FolderName/LoadPicture.aspx?Indx=2' is not a valid virtual path

Any Idea?

hi

You can save the image in temp file

Hope this helps...

hi,
i am back to my problem (export rad grid to pdf).

my applicatoin is defined as WebSite under IIS.
i have a folder (defined outside my application).
this folder defined under IIS.
in grid (prometeus) i defined :
ImageUrl = "http://serverName/FolderName/ImageName.jpg"
so :
1.i can create there a picture (it works)
2.i can show the picture in grid(it works also)
3.when i try to export grid to pdf :
 There is an error :
http://serverName/FolderName/ImageName.jpg invalid virtual path

how can i solve the problem?
is there some definition (in IIS/WebConfig...) that i am missing??

[plamen]

hi:


You can use only virtual path. The virtual path provides access to files outside the default directory and subdirectories. It appears in the form ".../~name/..." where "~name" is replaced with actual path configured by the administrator.


Thank you...

hello,
i am sorry - i need more specific example...
i don't have permition to access IIS , all definitions are done by another team.
i need to know what i am asking..
1. "the administrator definishon" - is how myFolder defined in IIS? 
   what is the correct definition?
3.the ImageUrl must be :
"../~myFolderNameInIIS/myPicture.jpg"
am i right?


thank you

Hey Mira,
You could define some setting in the web.config, which will hold the virtual directory path. You could ask the admins for the exact path then... I'm sorry I couldn't get how a more specific example would help - if you don't have access to the IIS you would not be able to run the export example as if it is in real mode...

As a side note, I'm pretty sure telerik will help once you send them the application?

Cheers,
