在GridView控件中，每行记录内会放置一个铵钮，当用户点击这个铵钮时，获取当笔记录的主键值。可看演示(是一个gif动画，重新播放尝试刷新网页):

实现这个功能，你需要为GridView控件设置DataKeyNames属性和OnRowCreated事件。

 

<

asp:GridView 

ID

="GridView1"

 runat

="server"

 AutoGenerateColumns

="false"

 DataKeyNames

="MediaTypeId"

                    OnRowCreated

="GridView1_RowCreated"

>

                    

<

Columns

>

                        

<!--

                            其它 TemplateField

                        

-->

                        

<

asp:TemplateField 

HeaderText

="Select"

>

                            

<

ItemTemplate

>

                                

<

asp:Button 

ID

="Button1"

 runat

="server"

 Text

="选择"

 

/>

                            

</

ItemTemplate

>

                        

</

asp:TemplateField

>

                    

</

Columns

>

                

</

asp:GridView

>

 

.aspx.cs代码：

 

protected

 

void

 GridView1_RowCreated(

object

 sender, GridViewRowEventArgs e)

    {

       

if

 (e.Row.RowType 

!=

 DataControlRowType.DataRow) 

return

;

        

if

 (e.Row.FindControl (

"

Button1

"

) 

!=

 

null

)

        {

            Button CtlButton 

=

 (Button)e.Row.FindControl (

"

Button1

"

);

            CtlButton.Click 

+=

new

 EventHandler(CtlButton_Click);

        }

    }

    

private

 

void

 CtlButton_Click(

object

 sender, EventArgs e)

    {

        Button button 

=

 (Button)sender;

        GridViewRow gvr 

=

 (GridViewRow)button.Parent.Parent;

        

string

 pk 

=

 GridView1.DataKeys[gvr.RowIndex].Value.ToString();

        

//

do something

InsusJsUtility objJs = new InsusJsUtility();
