GridView自定义编辑删除按钮

1、这是设计页面的代码，我简化了一下，关键是最后的一个模板列，用了3个图片，下面就是怎么处理3个图片的关系。编辑图片首先是能看见的，其它两个的Visible= false； view plaincopy to clipboardprint?01. 05. 06. 07. 08. 09. asp:Label ID=lbID runat=server Text=/ 10. 11. 12. 13. 14. 15. 16. asp:TextBox ID=tbNewsTitle runat=server Text= / 17. 18. 19. 20. asp:Label ID=lbNewsTitle run

2、at=server Text=/ 21. 22. 23. 24. 25. 26. 27. asp:TextBox ID=tbNewsContent runat=server Text= / 28. 29. 30. 31. asp:Label ID=lbNewsContent runat=server Text=/ 32. 33. 34. 35. 36. 37. 38. asp:TextBox ID=tbPublishTime runat=server Text= / 39. 40. 41. 42. asp:Label ID=lbPublishTime runat=server Text= 43

3、. 44. 45. 46. 47. 48. 49. 50. 51. 52. 53. 54. asp:Label ID=lbID runat=server Text=/ asp:TextBox ID=tbNewsTitle runat=server Text= / asp:Label ID=lbNewsTitle runat=server Text=/ asp:TextBox ID=tbNewsContent runat=server Text= / asp:Label ID=lbNewsContent runat=server Text=/ asp:TextBox ID=tbPublishTi

4、me runat=server Text= / asp:Label ID=lbPublishTime runat=server Text= 首先，定义两个全局变量 int editRow = -1; bool isEdit = false；用来控制和存储是要修改编辑哪一行，然后在cs代码中添加GridView1_RowCommand事件，在里面分别写上3个图片按钮的处理方法view plaincopy to clipboardprint?01.protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs

5、e) 02. if (e.CommandName = ibEdit) 04. 05. GridViewRow drv = (GridViewRow)(ImageButton)(e.CommandSource).Parent.Parent); /此得出的值是表示那行被选中的索引值 06. GridView gv = (GridView)(ImageButton)(e.CommandSource).Parent.Parent.Parent.Parent); 07. gv.EditIndex = drv.RowIndex; 08. isEdit =true; 09. TestCon(); 10. 1

6、1. 12. if (e.CommandName = ibCancel) 13. 14. GridView gv = (GridView)(ImageButton)(e.CommandSource).Parent.Parent.Parent.Parent); 15. gv.EditIndex = -1; 16. editRow = -1; 17. isEdit =false; 18. 19. TestCon(); 20. 21. if (e.CommandName = ibOk) 22. 23. GridViewRow drv = (GridViewRow)(ImageButton)(e.Co

7、mmandSource).Parent.Parent); 24. string tb1 = (TextBox)drv.FindControl(tbPublishTime).Text; 25. Response.Write(alert(TextBox的文字为： + tb1 + ); 26.测试作用，这里可以改成SQL更新语句。 27. 28. gv.EditIndex = -1; 29. editRow = -1; 30. isEdit =false; 31. 32. TestCon(); 33. 34. protected void GridView1_RowCommand(object se

8、nder, GridViewCommandEventArgs e) if (e.CommandName = ibEdit) GridViewRow drv = (GridViewRow)(ImageButton)(e.CommandSource).Parent.Parent); /此得出的值是表示那行被选中的索引值 GridView gv = (GridView)(ImageButton)(e.CommandSource).Parent.Parent.Parent.Parent); gv.EditIndex = drv.RowIndex; isEdit =true; TestCon(); if

9、 (e.CommandName = ibCancel) GridView gv = (GridView)(ImageButton)(e.CommandSource).Parent.Parent.Parent.Parent); gv.EditIndex = -1; editRow = -1; isEdit =false; TestCon(); if (e.CommandName = ibOk) GridViewRow drv = (GridViewRow)(ImageButton)(e.CommandSource).Parent.Parent); string tb1 = (TextBox)dr

10、v.FindControl(tbPublishTime).Text; Response.Write(alert(TextBox的文字为： + tb1 + ); /测试作用，这里可以改成SQL更新语句。 gv.EditIndex = -1; editRow = -1; isEdit =false; TestCon(); 然后在GridView1_RowDataBound中添加代码view plaincopy to clipboardprint?01. protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs

11、 e) 02. 03. if (isEdit) 04. 05. if (e.Row.RowIndex = editRow) 06. 07. (ImageButton)e.Row.FindControl(ibEdit).Visible = false; 08. 09. (ImageButton)e.Row.FindControl(ibOk).Visible = true; 10. (ImageButton)e.Row.FindControl(ibCancel).Visible = true; 11. / isEdit = ; 12. 13. 14. protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) if (isEdit) if (e.Row.RowIndex = editRow) (ImageButton)e.Row.FindControl(ibEdi
