Button with multiple CommandArguments??

[Jan Vetterli]

hi,

I'm wondering how I can achieve a button with a CommandArgument thats
dynamicly created from two or more DataBinder values, seperated with a ";"
so I can split the information up afterwards.


I've tried this (on the HTML page):

<asp:Button ID="NewButton" Runat="server" Text="New"
CommandName = "New"
CommandArgument ='<%# DataBinder.Eval(Container.Item, "ID")%> & ";" &
<%# DataBinder.Eval(Container.Item, "Name")%>'
</asp:Button>


With this code, I'll alway get an error msg. Can anybody help, please?

Thanks

Jan

I think we need to see the bigger picture here Jan - what are you trying to
achieve with this behaviour - maybe we can spot alternative approaches.

Hi Joe

This button will be placed in a Datarepeater ctrl. I want to use the
information thats included in the CommandArgument to supply me with
information like: how many times this item has been clicked and the ID of
the selected content of the Datarepeater. I can not use the CommandName for
this since I need it allready to supply me with more information from the
database.

I've found a way around this by just get the ID and execute a database
lookup, read the field with the stored information on how many times it has
been clicked, add 1 and write the new total of the click counter back to the
database.

I just thought it would be faster and easier to supply the value of the
click counter in the Datarepeater, and I really think there must be a way to
include two information strings in the CommandArgument.

I had this same problem here is how I solved it.


OnCommand="command_Click"
CommandArgument='<%# (Container.DataItem).String1 + "," + (Container.DataItem).String2 %>'

public void command_Click(object sender, EventArgs e)
{

string[] commandArgs = e.CommandArgument.ToString().Split(new char[] {','});

string1 = commandArgs[0];
string2 = commandArgs[1];
}
