今天有些時(shí)間，把用cs代碼添加編輯列及動(dòng)態(tài)添加編輯模板作了整理。動(dòng)態(tài)添加編輯列比較簡(jiǎn)單，即

TemplateField tf=new TemplateField(),但難得是 往編輯列里動(dòng)態(tài)添加編輯模版項(xiàng) ItemTemplate。那天上網(wǎng)找了好多資料，才找到解決方法。先創(chuàng)建一個(gè)類(lèi)繼承模板接口 ITemplate，用構(gòu)造函數(shù)實(shí)現(xiàn)返回Template類(lèi)。廢話(huà)不多說(shuō)了，現(xiàn)給出例子，看了就清楚了。例子延續(xù)前面的動(dòng)態(tài)綁定字段列的。

創(chuàng)建Template 的類(lèi) cs：GVItemTemplate.cs

public class GridViewItemTemplate:ITemplate

{

private string obj;? //控件對(duì)象的字符串，以此來(lái)判斷具體創(chuàng)建哪個(gè)控件

private DataControlRowType templateType;? //當(dāng)前行的模板 (Header，item)

private string colName;? //控件要顯示的字符，或是綁定數(shù)據(jù)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控件的頁(yè)面 cs代碼：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);

}
