推荐答案

在gridviewButton中设置CommandName(源代码)........
设置后
受保护的无效grvName_RowCommand(对象发送者，GridViewCommandEventArgs e)
{
如果(e.CommandName =="grvModify")
{
TextBox txt1 =(TextBox)grvPO.FindControl("txtname");
或
您的代码(输入karyo te类型)
int index = GridView1.EditIndex;
GridViewRow行= GridView1.Rows [index];
TextBox t1 = row.FindControl("txtemp_name")as TextBox;
TextBox t2 = row.FindControl("txtemp_add")as TextBox;
TextBox t3 = row.FindControl("txtemp_mob")as TextBox;
TextBox t4 = row.FindControl("txtsalary")as TextBox;
字符串t5 = GridView1.DataKeys [e.RowIndex] .Value.ToString();
字符串dt =更新员工集emp_name =""+ t1.Text +"''，emp_add =" + t2.Text +''，emp_mob =""+ t3.Text +"''，salary = ""+ t4.Text +"''其中emp_id ="+ t5 +";
con.Open();
cmd =新的SqlCommand(dt，con);
cmd.ExecuteNonQuery();
GridView1.EditIndex = -1;
con.Close();
bind();
}
}

Set CommandName in gridviewButton(Source Code) ........
after set
protected void grvName_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "grvModify")
{
TextBox txt1 = (TextBox)grvPO.FindControl("txtname");
or
your code(je te type karyo te)
int index = GridView1.EditIndex;
GridViewRow row = GridView1.Rows[index];
TextBox t1 = row.FindControl("txtemp_name") as TextBox;
TextBox t2 = row.FindControl("txtemp_add") as TextBox;
TextBox t3 = row.FindControl("txtemp_mob") as TextBox;
TextBox t4 = row.FindControl("txtsalary") as TextBox;
string t5= GridView1.DataKeys[e.RowIndex].Value.ToString();
string dt = "update employee set emp_name=''" + t1.Text + "'',emp_add=''" + t2.Text + "'',emp_mob=''" + t3.Text+ "'',salary=''" + t4.Text+ "''where emp_id=" + t5+ "";
con.Open();
cmd = new SqlCommand(dt, con);
cmd.ExecuteNonQuery();
GridView1.EditIndex = -1;
con.Close();
bind();
}
}
