今天有些时间，把用cs代码添加编辑列及动态添加编辑模板作了整理。动态添加编辑列比较简单，即

TemplateField tf=new TemplateField(),但难得是 往编辑列里动态添加编辑模版项 ItemTemplate。那天上网找了好多资料，才找到解决方法。先创建一个类继承模板接口 ITemplate，用构造函数实现返回Template类。废话不多说了，现给出例子，看了就清楚了。例子延续前面的动态绑定字段列的。

创建Template 的类 cs：GVItemTemplate.cs

public class GridViewItemTemplate:ITemplate

{

private string obj;  //控件对象的字符串，以此来判断具体创建哪个控件

private DataControlRowType templateType;  //当前行的模板 (Header，item)

private string colName;  //控件要显示的字符，或是绑定数据源的字段列名

public GridViewItemTemplate(DataControlRowType rtype, string controlStr, string colN)

{

templateType = rtype;

colName = colN;

obj = controlStr;

}

public GridViewItemTemplate(DataControlRowType rtype, string colN)

{

templateType = rtype;

colName = colN;

obj = "TextBox";

}

public void InstantiateIn(System.Web.UI.Control container)

{

switch (templateType)

{

case DataControlRowType.Header:

Literal headlt = new Literal();

headlt.Text = colName;

container.Controls.Add(headlt);

break;

case DataControlRowType.DataRow:

switch (obj.ToLower())

{

case "htmlcheckbox":

HtmlInputCheckBox cbkeys = new HtmlInputCheckBox();

cbkeys.ID = "cb_keys";

cbkeys.DataBinding += new EventHandler(this.CheckBoxDataBinding);

container.Controls.Add(cbkeys);

break;

default:

TextBox myTextBox = new TextBox();

myTextBox.DataBinding += new EventHandler(this.TextBoxDataBinding);

container.Controls.Add(myTextBox);

break;

}

break;

default:

break;

}

}

private void TextBoxDataBinding(Object sender, EventArgs e)

{

TextBox myTextBox = (TextBox)sender;

GridViewRow row = (GridViewRow)myTextBox.NamingContainer;

myTextBox.Text = System.Web.UI.DataBinder.Eval(row.DataItem, colName).ToString();

}

private void CheckBoxDataBinding(Object sender, EventArgs e)

{

GridViewRow row=null;

switch (obj.ToLower())

{

case "htmlcheckbox":

HtmlInputCheckBox hcbox = (HtmlInputCheckBox)sender;

row= (GridViewRow)hcbox.NamingContainer;

hcbox.Value = System.Web.UI.DataBinder.Eval(row.DataItem, colName).ToString();

break;

default:

CheckBox cbox = (CheckBox)sender;

row = (GridViewRow)cbox.NamingContainer;

cbox.Text = System.Web.UI.DataBinder.Eval(row.DataItem, colName).ToString();

break;

}

}

}

使用GridView控件的页面 cs代码：TestGridView.aspx.cs

void BindFields(int tbid)

{

TemplateField tf = new TemplateField();

tf.ItemTemplate = new GridViewItemTemplate(DataControlRowType.DataRow, "htmlcheckbox", "dataKey");

tf.HeaderTemplate = new GridViewItemTemplate(DataControlRowType.Header, "htmlcheckbox", "");

tf.HeaderStyle.CssClass = "cbox";

this.gv_Data.Columns.Add(tf);

}
