Repeater中找到控件&Repeater中的Button处理

Repeater中找到控件
分析：循环所有Repeater中的Item即可
在Repeater1.DataBind()后加入

            int count = Repeater1.Items.Count;
            for (int i = 0; i < count; i++)
            {
                TextBox cjry = Repeater1.Items[i].FindControl("txt_Cjry") as TextBox;
            }

Repeater中的Button处理
前台：

<asp:Button ID="btn_Edit" runat="server" Text="修 改" CommandName="edit" CommandArgument='<%#Bind("id") %>' />

后台：

        protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
        {
            if (e.CommandName == "edit")
            {
                RepeaterItem ri = e.Item;
                TextBox ycjrs_child = ri.FindControl("txt_Ycjrs") as TextBox;
                TextBox scjrs_child = ri.FindControl("txt_Scjrs") as TextBox;
                TextBox cjry_child = ri.FindControl("txt_Cjry") as TextBox;
                TextBox qxr_child = ri.FindControl("txt_Qxr") as TextBox;
                TextBox ldqz_child = ri.FindControl("txt_Ldqz") as TextBox;
                TextBox zcr_child = ri.FindControl("txt_Zcr") as TextBox;
                TextBox jlr_child = ri.FindControl("txt_Jlr") as TextBox;
                TextBox hdnr_child = ri.FindControl("txt_Hdnr") as TextBox;
                TextBox fyjl_child = ri.FindControl("txt_Fyjl") as TextBox;
                TextBox fxgz_child = ri.FindControl("txt_Fxgz") as TextBox;
                TextBox bkqk_child = ri.FindControl("txt_Bkqk") as TextBox;
                int id_user = Convert.ToInt32(Session["id"].ToString());
                DataSet ds = new DataSet();
                using (SqlConnection conn = new SqlConnection(strConn))
                {
                    conn.Open();
                    string strCmd = "update [hdjl] set [ycjrs]=@ycjrs,[scjrs]=@scjrs,[cjry]=@cjry,[qxr]=@qxr,[ldqz]=@ldqz,[zcr]=@zcr,[jlr]=@jlr,[hdnr]=@hdnr,[grfyjl]=@grfyjl,[fxgz]=@fxgz,[bkqk]=@bkqk,[id_user]=@id_user where [id]=@id";
                    using (SqlCommand cmd = new SqlCommand(strCmd, conn))
                    {
                        cmd.Connection = conn;
                        cmd.Parameters.AddWithValue("@ycjrs", ycjrs_child.Text.ToString());
                        cmd.Parameters.AddWithValue("@scjrs", scjrs_child.Text.ToString());
                        cmd.Parameters.AddWithValue("@cjry", cjry_child.Text.ToString());
                        cmd.Parameters.AddWithValue("@qxr", qxr_child.Text.ToString());
                        cmd.Parameters.AddWithValue("@ldqz", ldqz_child.Text.ToString());
                        cmd.Parameters.AddWithValue("@zcr", zcr_child.Text.ToString());
                        cmd.Parameters.AddWithValue("@jlr", jlr_child.Text.ToString());

                        cmd.Parameters.AddWithValue("@fxgz", fxgz_child.Text.ToString());
                        cmd.Parameters.AddWithValue("@bkqk", bkqk_child.Text.ToString());
                        cmd.Parameters.AddWithValue("@id_user", id_user);
                        cmd.Parameters.AddWithValue("@id", e.CommandArgument);
                        if (cmd.ExecuteNonQuery() > 0)
                        {
                            ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('修改成功');location.href='hdjl_query.aspx'</script>");
                        }
                    }
                }
            }
