Pass object as CommandArguement in a Repeater Link Button

Question

I have a Repeater with a list of Customers. Against each customer there is a delete link button. As part of the linkbutton I want to pass the Customer object to the Command Arguement as follows (where Container.DataItem is the customer object):

<asp:LinkButton  ID="lnkDelete" 
   OnClientClick="return confirmDelete();"  
   OnClick="Customer_OnDelete"  
   CommandArgument="<%# Container.DataItem  %>"  
   CommandName="Delete" 
   runat="server"></asp:LinkButton>

When I do this:

    var button = (((LinkButton) sender));

    var customer=  button.CommandArgument;

button.CommandArguement is a string. I need all the object properties as we are using Nhibernate so everything needs to be set, the ID of the deleted record is not enough. I have seen examples online regarding passing a comma seperated list of values into the command arguement but want to avoid doing that. Is this possible?

Any ideas? Thanks

In my opinion the best way for this case is:

• Get the ID from CommandArgument
• Get the Customer by ID
• Delete the Customer Entity

Use the Repeater event OnItemCommand. This event contains RepeaterCommandEventArgs. You cant get the CommandArgument this way:

protected void myRepeater_ItemCommand(object source, RepeaterCommandEventArgs e)
{
   int customerID= Convert.ToInt32(e.CommandArgument.ToString());
}

At your asp:LinkButton tag use:

CommandArgument='<%# DataBinder.Eval(Container.DataItem, "ID") %>'
