Hello all,
My basic problem is that my LinkButton does not support a data bound
CommandArgument property under certain cases. The intent is to filter my
datagrid based on a specific row's value, so one query might return players
from multiple schools; clicking on a player row's school linkbutton will
filter the previous query to that school.
The linkbuttons bind properly (including the commandArgument ) when the
templatecolumn is early in the columns collection. Later in the collection,
given a certain state, I remove two of the columns from the collection,
because data is not available to populate them. Unfortunately, if I put the
tempate column that contains the Linkbutton with the bound CommandArgument
property after the deleted columns, the command argument always shows up as
an empty string, "".
I'm stumped. I am getting ready to just databind the DataTable and query
the table based on the row index - but is resource intensive, and clunky,
especially on higher data pages.
Any suggestions?

I said databind the DataTable in the last paragraph - I mean to say store the
DataTable in the ViewState.
Also, if I debug the application, immediately after the databind occurs,
examination of the DataGrid1.Items[0].Cells[ IndexOfLinkButt onCell
].Controls[ IndexToLinkButt onControl ].CommandArgumen t reveals the correct
value. So something is being lost between this point and when I receive
control in the DataGrid_ItemCo mmand event.

Success.
I figured out a solution. The reason I wanted to remove the invalid columns
was because my application would raise an exception when it was trying to
databind the BoundColumns (the error was that the column reference didn't
exist in the DataTable.) I had tried previously to just set the invalid
columns visible propety to false, but the error would still raise. So now,
for the bound columns, I set the DataField property to null, then set the
visible property to false, instead of removing the columns entirely. Now the
CommandArgument property on the later columns is preserved correctly!

Hello
Could anyone please explain how I can pass more than one
arguement/parameter value to a function using <asp:linkbutton> or is
this a major shortfall of the language ?
Consider the following code fragments in which I want to list through
all files on a directory with a link to download each file by passing
a filename and whether or not to force the download dialog box to
appear.

I am creating an aspx page using C# and would like to be able to dynamically
create linkbuttons that all run the same fuction on the click event. However,
I would like the function to accept a single argument (in this case the file
name) to identify which button was clicked. I am using the Command event
handler.
The link buttons load correctly, but when i click on a link, the event
handler code does not execute.
Any ideas?

The intended functionality is as follows :

Hi,
I have a strange issue occurring with LinkButtons that are dynamically added
to each (data) row of my DataGrid on that grid's ItemDataBound event. Each
LinkButton is assigned its own event handler to deal with the Command event,
but for some reason I can get this to work in a C# project but not in a newly
created VB.NET one.
The relevant VB.NET is as follows:
