用处及效果
准备工作
这个是在前面表格的基础上，扩展了自定义行实现的，当然也修改了一些列表控件以兼容
如果对前面的表格控件不了解，请移步查看
开始
实现树表格的思路就是，在行控件中再添加一个无标题的表格控件，当需要显示子节点的时候，将子节点数据加载到行里的表格控件中，然后处理一下事件，让事件可以穿透到最顶层就行了。
另外我们前面表格中的行个数是根据高度大小自动计算的，这里就会出现问题，当出现子节点表格的时候，就会导致重算个数和高度，所有我们在表格列表控件增加一个属性来禁用这个自动计算。
添加一个用户控件，命名ucdatagridviewtreerow，实现接口idatagridviewrow
属性

34 {
35 if (m_ischecked != value)
36 {
37 m_ischecked = value;
38 (this.pancells.controls.find("check", false)[0] as uccheckbox).checked = value;

50 set
51 {
52 m_rowheight = value;
53 this.height = value;
54 }
55 }
56 #endregion
构造函数处理一写东西，注意 this.ucdgvchild.itemclick ，这个是将子节点表格的点击事件向上传递
1 public ucdatagridviewtreerow()
2 {
3 initializecomponent();
4 this.ucdgvchild.rowtype = this.gettype();
5 this.ucdgvchild.isautoheight = true;
6 this.sizechanged += ucdatagridviewtreerow_sizechanged;
7 this.ucdgvchild.itemclick += (a, b) =>
8 {
9 if (cellclick != null)
10 {
11 cellclick(a, new datagridvieweventargs()
12 {
13 cellcontrol = (a as control),
14 cellindex = (a as control).tag.toint()
15 });
16 }
17 };
18
19 }
实现接口函数bindingcelldata，主要处理一下数据绑定后将子节点数据向下传递
1 public void bindingcelldata()
2 {
3 for (int i = 0; i < columns.count; i++)
4 {
5 datagridviewcolumnentity com = columns[i];
6 var cs = this.pancells.controls.find("lbl_" + com.datafield, false);
7 if (cs != null && cs.length > 0)
8 {
9 var pro = datasource.gettype().getproperty(com.datafield);
10 if (pro != null)
11 {
12 var value = pro.getvalue(datasource, null);
13 if (com.format != null)
14 {
15 cs[0].text = com.format(value);
16 }
17 else
18 {
19 cs[0].text = value.tostringext();
20 }
21 }
22 }
23 }
24 panleft.tag = 0;
25 var prochildrens = datasource.gettype().getproperty("childrens");
26 if (prochildrens != null)
27 {
28 var value = prochildrens.getvalue(datasource, null);
29 if (value != null)
30 {
31 int intsourcecount = 0;
32 if (value is datatable)
33 {
34 intsourcecount = (value as datatable).rows.count;
35 }
36 else if (typeof(ilist).isassignablefrom(value.gettype()))
37 {
38 intsourcecount = (value as ilist).count;
39 }
40 if (intsourcecount > 0)
41 {
42 panleft.backgroundimage = properties.resources.caret_right;
43 panleft.enabled = true;
44 panchildgrid.tag = value;
45 }
46 else
47 {
48 panleft.backgroundimage = null;
49 panleft.enabled = false;
50 panchildgrid.tag = null;
51 }
52 }
53 else
54 {
55 panleft.backgroundimage = null;
56 panleft.enabled = false;
57 panchildgrid.tag = null;
58 }
59 }
60 else
61 {
62 panleft.backgroundimage = null;
63 panleft.enabled = false;
64 panchildgrid.tag = null;
65 }
66 }
实现函数绑定列

13 {
14 intcolumnscount++;
15 }
16 this.pancells.columncount = intcolumnscount;
17 for (int i = 0; i < intcolumnscount; i++)
18 {
19 control c = null;
20 if (i == 0 && isshowcheckbox)
21 {
22 this.pancells.columnstyles.add(new system.windows.forms.columnstyle(sizetype.absolute, 30f));
23
24 uccheckbox box = new uccheckbox();
25 box.name = "check";
26 box.textvalue = "";
27 box.size = new size(30, 30);
28 box.dock = dockstyle.fill;
29 box.checkedchangeevent += (a, b) =>
30 {
31 ischecked = box.checked;
32 this.ucdgvchild.rows.foreach(p => p.ischecked = box.checked);
33 if (checkboxchangeevent != null)
34 {
35 checkboxchangeevent(a, new datagridvieweventargs()
36 {
37 cellcontrol = box,
38 cellindex = 0
39 });
40 }
41 };
42 c = box;
43 }
44 else
45 {
46 var item = columns[i - (isshowcheckbox ? 1 : 0)];
47 this.pancells.columnstyles.add(new system.windows.forms.columnstyle(item.widthtype, item.width));
48
49 label lbl = new label();
50 lbl.tag = i - (isshowcheckbox ? 1 : 0);
51 lbl.name = "lbl_" + item.datafield;
52 lbl.font = new font("微软雅黑", 12);
53 lbl.forecolor = color.black;
54 lbl.autosize = false;
55 lbl.dock = dockstyle.fill;
56 lbl.textalign = contentalignment.middlecenter;
57 lbl.mousedown += (a, b) =>

59 item_mousedown(a, b);
60 };
61 c = lbl;
62 }
63 this.pancells.controls.add(c, i, 0);
64 }
65
66 }
67 }
68 finally
69 {
70 controlhelper.freezecontrol(this, false);
71 }
72 }
当点击展开图标的时候处理子节点的数据绑定以及高度计算
1 private void panleft_mousedown(object sender, mouseeventargs e)
2 {
3 try
4 {
5 controlhelper.freezecontrol(this.findform(), true);
6 if (panleft.tag.toint() == 0)
7 {
8 var value = panchildgrid.tag;
9 if (value != null)
10 {
11 panleft.backgroundimage = properties.resources.caret_down;
12 panleft.tag = 1;
13 int intsourcecount = 0;
14 if (value is datatable)
15 {
16 intsourcecount = (value as datatable).rows.count;
17 }
18 else if (typeof(ilist).isassignablefrom(value.gettype()))
19 {
20 intsourcecount = (value as ilist).count;
21 }
22 this.panchildgrid.height = rowheight * intsourcecount;
23 if (panchildgrid.height > 0)
24 {
25 if (value != this.ucdgvchild.datasource)
26 {
27 this.ucdgvchild.columns = columns;
28 this.ucdgvchild.rowheight = rowheight;
29 this.ucdgvchild.headpadingleft = this.panleft.width;
30 this.ucdgvchild.isshowcheckbox = isshowcheckbox;
31 this.ucdgvchild.datasource = value;
32 this.ucdgvchild.rows.foreach(p => p.ischecked =this.ischecked);
33 }
34 }
35 }
36
37 }
38 else
39 {
40 panleft.tag = 0;
41 panchildgrid.height = 0;
42 panleft.backgroundimage = properties.resources.caret_right;
43 }
44 }
45 finally
46 {
47 controlhelper.freezecontrol(this.findform(), false);
48 }
49 }
承载子节点表格的panel 在大小改变的时候，处理父级表格的大小。来防止出现多个滚动条
1 void ucdatagridviewtreerow_sizechanged(object sender, eventargs e)
2 {
3 if (this.parent.parent.parent != null && this.parent.parent.parent.name == "panchildgrid" && this.panleft.tag.toint() == 1)
4 {
5 int intheight = this.parent.parent.controls[0].controls.toarray().sum(p => p.height);
6 if (this.parent.parent.parent.height != intheight)
7 this.parent.parent.parent.height = intheight;

我这里写死了，如果要使用树表格的话，子数据就要用属性childrens，比如下面的实体就是了
public class testmodel
{
public string id { get; set; }
public string name { get; set; }
public int age { get; set; }
public datetime birthday { get; set; }
public int sex { get; set; }
public list<testmodel> childrens { get; set; }
}
使用实例如下
1 this.ucdatagridview1.rowtype = typeof(ucdatagridviewtreerow);
2 this.ucdatagridview1.isautoheight = true;
3
4 list<datagridviewcolumnentity> lstculumns = new list<datagridviewcolumnentity>();
5 lstculumns.add(new datagridviewcolumnentity() { datafield = "id", headtext = "编号", width = 70, widthtype = sizetype.absolute });
6 lstculumns.add(new datagridviewcolumnentity() { datafield = "name", headtext = "姓名", width = 50, widthtype = sizetype.percent });
7 lstculumns.add(new datagridviewcolumnentity() { datafield = "age", headtext = "年龄", width = 50, widthtype = sizetype.percent });
8 lstculumns.add(new datagridviewcolumnentity() { datafield = "birthday", headtext = "生日", width = 50, widthtype = sizetype.percent, format = (a) => { return ((datetime)a).tostring("yyyy-mm-dd"); } });
9 lstculumns.add(new datagridviewcolumnentity() { datafield = "sex", headtext = "性别", width = 50, widthtype = sizetype.percent, format = (a) => { return ((int)a) == 0 ? "女" : "男"; } });
10 this.ucdatagridview1.columns = lstculumns;
11 this.ucdatagridview1.isshowcheckbox = true;
12 list<object> lstsource = new list<object>();
13 for (int i = 0; i < 200; i++)
14 {
15 testmodel model = new testmodel()
16 {
17 id = i.tostring(),
18 age = 3 * i,
19 name = "姓名——" + i,
20 birthday = datetime.now.addyears(-10),
21 sex = i % 2
22 };
23 lstsource.add(model);
24 addchilds(model, 5);
25 }
26
27 var page = new ucpagercontrol2();
28 page.datasource = lstsource;
29 this.ucdatagridview1.page = page;
30 this.ucdatagridview1.first();
31
32
33
34
35 private void addchilds(testmodel tm, int intcount)
36 {
37 if (intcount <= 0)
38 return;
39 tm.childrens = new list<testmodel>();
40 for (int i = 0; i < 5; i++)
41 {
42 testmodel model = new testmodel()
43 {
44 id = i.tostring(),
45 age = 3 * i,
46 name = intcount + "——" + i,
47 birthday = datetime.now.addyears(-10),
48 sex = i % 2
49 };
50 tm.childrens.add(model);
51 addchilds(model, intcount - 1);
52 }
53 }
