Right syntax of Button Onclick Event in Repeater

Question

I use a repeater Control to display all the comments from Datatable :

COMMENT(id,content,time);

In repeater I insert a button Delete to Delete that correlative comment

I wonder if I can add an variable " string id " in ButtonDelete_Click() like:

protected void ButtonDelete_Click(object sender, EventArgs e, string id)
{
     int idcm = Convert.ToInt32(id);
     string sql = "delete from COMMENT where ID=" + idcm;
     l.EXECUTEQUERYSQL(sql);
     ErrorTrap("DONE");//alert deleted sucessfully
}

And in aspx page:

<Repeater...>
    <asp:Button ID="ButtonDelete" runat="server" Text="Delete comment" 
         OnClick="ButtonDelete_Click(<%#Eval("MA_COMMENT") %>)"/>
    ....
</Repeater>

But when I build this page, an error ocur: The server tag is not well formed. at line:

<asp:Button ID="ButtonDelete" runat="server" Text="Delete comment" 
     OnClick="ButtonDelete_Click(<%#Eval("MA_COMMENT") %>)"/>

It is the first time I use Repeater Control, so I really dont know how is the right syntax? And I wonder if I can add more variales in ButtonDelete_Click Event or not???

Help!

Answer 1

you can use the command argument property fot the button and grap it in the click event :

<asp:Button ID="ButtonDelete" runat="server" Text="Delete comment" 
         OnClick="ButtonDelete_Click()" CommandArgument='<%#Eval("MA_COMMENT") %>'/>

on the click event

void ButtonDelete (object sender, EventArgs e)
  {

     var id = int.parse(e.CommandArgument.ToString());

  }

Hope this is helpful

Answer 2

use this

OnClick='ButtonDelete_Click(<%#Eval("MA_COMMENT") %>)'

or try replacing ' to " it should work.
