In your rpChat_ItemCommandevent of the Button you can get the textBox value

protected void rpChat_ItemCommand(Object Sender, RepeaterCommandEventArgs e)
{
   if(e.CommandName == "Insert")
   {
    TextBox txtChatMessage= (TextBox)e.item.FindControl("txtChatMessage");
    if (txtChatMessage!= null)
    {
        string val = txtChatMessage.Text;
    }
   }
}

The problem with your code is that it will **always** return the first textbox in the first row. Not the **current textbox in the current row** – Jupaol Jul 22 '12 at 16:27

You do not need to iterate the whole Items collection, simply do this:

ASPX

<asp:Button Text="text" CommandName="myCommand" runat="server" ID="txtFirstName" />

Code behind

protected void r_ItemCommand(object sender, RepeaterCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "myCommand":
            var txt = e.Item.FindControl("txtFirstName") as TextBox;
            var myValue = txt.Text;
            // place your awesome code here
            break;
    }
}

The code works. In your case it isn't because the control you are looking for is in a nested server control: `
` that's the reason, you would have to change the call `var txt = e.Item.FindControl("txtFirstName") as TextBox;` to use a recursive search. Check this link: http://stackoverflow.com/questions/4955769/better-way-to-find-control-in-asp-net
