让Buttonfield执行javascript

Question

我想在网格视图的ButtonField的单击上执行JavaScript函数

因为没有onclick或onclient click present

  <asp:ButtonField HeaderText="Submit" Text="Submit" CommandName="Submit"  />

Answer 1

在grdRewards_RowDataBound中，我们可以编写

  If e.Row.RowType = DataControlRowType.DataRow Then
       Dim btnbutton As LinkButton = DirectCast(e.Row.Cells(13).Controls(0), LinkButton)
       btnbutton.Attributes.Add("onclick", "javascript:return ShowDialog()")

Answer 2

处理RowDataBound事件。

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
           //Presume that the buttonField is at 1st cell
            LinkButton link = e.Row.Cells[0].Controls[0] as LinkButton;

            if (link != null)
            {
                link.Attributes.Add("onclick", "alert('Hello');");
            }
        }
    }

Answer 3

你不能在这种情况下使用ButtonField，最好检查一下史蒂夫回答的Javascript before asp:ButtonField click。

编码快乐!！
