            {
                foreach (RepeaterItem ri in repeater1.Items)
                {
                    HtmlInputCheckBox chkId = (HtmlInputCheckBox)ri.FindControl("chkId");
                    Label lblTemplateID = (Label)ri.FindControl("lblTemplateID");
                    if (chkId != null)
                    {
                        if (chkId.Checked)
                        {
                            //your delete code is here
                        }
                    }
                }
                PopulateEMP();

            }
        }

If you want to delete the multiple record from the datalist the use the Datakeys property.

// put your delete button here it is not same as repeater.

 <asp:Button ID="bntDelete" runat="server" Text="Delete EMP" />&nbsp;&nbsp

<asp:DataList ID="DataList 1" runat="server" DataKeyField="EmpID" CssClass="gridtable">

///same as repeater code is here

///

<asp:DataList>

Dlete button code is :

  protected void btnDelete_Click(object sender, EventArgs e)
        {
            foreach (DataListItem di in DataList1.Items)
            {
                HtmlInputCheckBox chkId = (HtmlInputCheckBox)di.FindControl("chkId");
                if (chkId != null)
                {
                    if (chkId.Checked)
                    {
                       // your delete code is here.
                    }
                }
            }
                          PopulateEMP();

        }
