Dynamically add custom controls to the flow layout with simple button paging technology

Since nothing recently, has been looking at the Java Foundation, a few days ago received the task of the superior, you have to make an access control system of the CS interface out, to achieve paging, data binding requirements such as

See here, because I basically did not contact the CS thing, a time only two or three ideas, the first idea is: the Custom control +panle control (ultimately feel not working not to do) The second idea is: Custom control +datagridview Control, try for a few days, feel a bit cumbersome, It is not necessarily possible to achieve this effect; The third idea is: custom control + Flow layout + automatic generation. I finally made it through the third Way; the fourth idea is that WCF has only this idea, not yet implemented, because it has not yet learned about WCF. First of all: I define my own custom controls first, and the code and effects are as follows:

Using system.data;using system.data.sqlclient;namespace menu{partial class MyControl {//<summary>        Clean up all the resources that are in use. </summary>//<param name= "disposing" > True if the managed resource should be released, otherwise false. </param> protected override void Dispose (bool disposing) {if (disposing && (compon Ents = null)) {components.            Dispose (); } base.        Dispose (disposing);        The code generated by the #region Component Designer///<summary>///designer supports the required method-do not use the Code Editor to modify the contents of this method. </summary> private void InitializeComponent () {this.components = new System.componentm Odel.

The custom control effect is as follows:

Step Two: Stream layout + dynamically add custom controls

The implementation code and effects are as follows:

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;namespacemenu{ Public Partial classForm3:form { PublicForm3 () {InitializeComponent (); }        Private voidForm3_load (Objectsender, EventArgs e) {                    }                Private voidButton1_Click (Objectsender, EventArgs e) {             This. FlowLayoutPanel1.Controls.Clear (); N=n+1; intCount = the*N;  for(intI=1+ the* (n1); i<=count;i++) {mycontrol MCL=Newmycontrol (); Mcl.groupBox1.Text=i.tostring (); McL.                Dataload (i);  This. FLOWLAYOUTPANEL1.CONTROLS.ADD (MCL); }        }        intn =1; Private voidButton3_Click (Objectsender, EventArgs e) {             This. FlowLayoutPanel1.Controls.Clear (); intCount = the*N;  for(inti =1; I <= count; i++) {mycontrol MCL=Newmycontrol (); Mcl.groupBox1.Text=i.tostring (); McL.                Dataload (i);  This. FLOWLAYOUTPANEL1.CONTROLS.ADD (MCL); }        }        Private voidButton2_Click (Objectsender, EventArgs e) {             This.
