ASP.NET 2 Data Bound CommandArgument

rodmcleay · October 2nd, 2004, 01:59 AM

I am using c# and VS.NET 2005 Beta.
Sorry for not using the VS.NET 2005 Forum, but I am unsure if anyone is subscribed to it and this is fairly urgent.

Using a datagrid in the ASP.NET 1.1 I pased a value to the code behind from the item created event using the commandArgument attribute of the conrol I was using.
EG.

Code:

<asp:ImageButton ID="DownloadImageButton" SkinID="IconButton_Download" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "Name")%>'  Runat="Server" />

Now in ASP.NET 2 the attrubute does not seem to like taking the databound value.
If I hard code all is fine
EG

Code:

<asp:ImageButton ID="DownloadImageButton" SkinID="IconButton_Download" CommandArgument="c:/MyFile.txt"  Runat="Server" />

I have also tried

Code:

CommandArgument='<%# Eval("FullName")%>'

Which I beleive to be a valid shortcut now.

The IDE does not even seem to recognise the server script tags.
Can anyone tell me if the process of binding data to gridview/datagrid attributes has changes in ASP.NET 2?
Any assistance would be greatly appreciated.

Solution Found.

There was nothing wrong with the command argument at all.
Just needed to access it in the databound event instead of the created event.

Hi,
This is a while back now (2yrs) so I cant be sure what my problem was.
But basically there are several events fired by the datagrid, one being OnItemDataBound and another being OnItemCreated.
There are others.
The command arguement I was looking for could not be found in the databound event, but was available in the ItemCreated event.
This is probably because the actual control that contains the command arguement is not created yet at that stage.
I hope this helps.

                Label1.Text = "ruta a " + Server.MapPath(rutaDir + e.CommandArgument);
                RellenaDatagrid(Server.MapPath(rutaDir + e.CommandArgument));
                break;
            default:
                Label1.Text = "Comando no reconocido.";
                break;
        }

    }
