asp.net中有关gridview控件添加编辑按钮的示例(一)
微软为.net中的gridview添加了编辑,删除等处理事件,可是我们想要自己添加这些功能,下面我来介绍一下编辑按钮的示例,我用的是VS2008:
在gridview控件中的列编辑框中添加一列textbox的模板,命名为txt1,:编辑,更新,取消,命令列,首先它是系统生成的东西,当我们选中它时,在右则属性栏中其类型为Link,将其ButtonType调整为Button,并将其转化为TemplateField,然后为gridview控件添加Rowediting事件,并添加如下处理代码:

GridView2.EditIndex = e.NewEditIndex;
//当前编辑行背景色高亮
this.GridView2.EditRowStyle.BackColor = Color.FromName("#F7CE90");
string strSQL = "";
strSQL = "select * from userliuyan ";
try
{
GridView2.DataSource = ws.GetWritersBig(strSQL, CommandType.Text, null);
GridView2.DataBind();
}
catch (Exception)
{
throw;
}
//当前编辑行背景色高亮
this.GridView2.EditRowStyle.BackColor = Color.FromName("#F7CE90");
string strSQL = "";
strSQL = "select * from userliuyan ";
try
{
GridView2.DataSource = ws.GetWritersBig(strSQL, CommandType.Text, null);
GridView2.DataBind();
}
catch (Exception)
{
throw;
}
添加更新事件:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
string ID = GridView2.DataKeys[e.RowIndex].Values[0].ToString();
string answer = ((TextBox)GridView2.Rows[e.RowIndex].FindControl("txt1")).Text;
//判断表单项是否有空并给出提示信息
if (answer == "" &&answer.Length>500)
{
Response.Write("<script>alert('请输入完整信息!')</script>");
return;
}
string sqltxt = "update userliuyan set lAnswer='" + answer + "' where lId=" + ID;
int id = 0;
//把文本框中的内容更新到数据库不写了
if (id != 0)
{
Response.Write("<script language='javascript'>alert('数据已被保存!');</script>");
//返回浏览状态
string strSQL = "";
strSQL = "select * from userliuyan ";
try
{
GridView2.DataSource = ws.GetWritersBig(strSQL, CommandType.Text, null);
GridView2.DataBind();
}
catch (Exception)
{
throw;
}
}
string answer = ((TextBox)GridView2.Rows[e.RowIndex].FindControl("txt1")).Text;
//判断表单项是否有空并给出提示信息
if (answer == "" &&answer.Length>500)
{
Response.Write("<script>alert('请输入完整信息!')</script>");
return;
}
string sqltxt = "update userliuyan set lAnswer='" + answer + "' where lId=" + ID;
int id = 0;
//把文本框中的内容更新到数据库不写了
if (id != 0)
{
Response.Write("<script language='javascript'>alert('数据已被保存!');</script>");
//返回浏览状态
string strSQL = "";
strSQL = "select * from userliuyan ";
try
{
GridView2.DataSource = ws.GetWritersBig(strSQL, CommandType.Text, null);
GridView2.DataBind();
}
catch (Exception)
{
throw;
}
}
这样一个简单的编辑功能就完成了
