关于在GridView中删除提示的问题

Question

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
    {
 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            {
                ((Button)e.Row.FindControl("Button1")).Attributes.Add("onclick", "javascript:return   confirm(‘确定要删除吗')");            }
        }
     
    }
怎么提示 “未将对象引用设置到对象的实例。” 谢谢 

Answer 1

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e) 
    {         if (e.Row.RowType == DataControlRowType.DataRow) 
        { 
           // if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)   多余的语名不需要
           // { 
                ((Button)e.Row.FindControl("Button1")).Attributes.Add("onclick", "javascript:return  confirm('确定要删除吗')");           //  } 
        } 
    
    } //confirm中的单引号有问题，为英文才对！

Answer 2

((Button)e.Row.Cells[Button1所在的列索引].Controls[0]).Attributes.Attributes.Add("onclick", "javascript:return  confirm(‘确定要删除吗')"); 
或者
  ((Button)e.Row.Cells[Button1所在的列索引].FindControl("Button1")).Attributes.Add("onclick", "javascript:return  confirm(‘确定要删除吗')"); 

Answer 3

是在不行，返璞归真。。protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e) 
    { 
        if (e.Row.RowType == DataControlRowType.DataRow) 
        { 
            if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate) 
            { 
                Literal txtMsg = new Literal();
                txtMsg.Text = "<script>alert('未将对象引用设置到对象的实例')</script>";
                Page.Controls.Add(txtMsg);
            } 
        } 
    } 

Answer 4

搞错了，应当写到事件RowDataBound事件中
   protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

Answer 5

还不行就是你判断条件有问题咯，你断点看下能不能RUN到里面去，可能根本就没进去。

Answer 6

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //如果是绑定数据行 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
             if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            {
                ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text + "\"吗?')");
            }
        } 
    }
