在.net2.0中,怎么样实现对gridview删除行时弹出确认对话框

1,GridView中如何使用CommandField删除时,弹出确认框?
在.net2005提供的GridView中我们可以直接添加一个CommandField删除列:,完后在它的RowDeleting事件中完成删除。但在多半我们在做这种删除操作时都需要先让操作者再确认下,完后再进行删除,以避免误操作引起的误删除。
可以通过下面方法给GridView删除前加上个确认对话框。
首先,在GridView的属性对框话框中点击“Columns”进入它的“字段”设计器。接着在“字段”设计器中选择以前已加上的那个CommandField“删除”列,这时在它的属性列表下会看到一个“将此它段转换为 TemplateFied”的项,点击将它转换为TemplateFied列。
完后退出该字段设计器,切换到源码视图你会发现该列已由原来的:
变为了:
最后在中加入:OnClientClick="return confirm(确认要删除吗?);"
这样点击删除时就会先在客户端弹出“确认要删除吗?”对话框,而原来在RowDeleting事件中写的代码完全不用改变。
2,
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowIndex > -1)
{
int id = Convert.ToInt32(GridView1.DataKeys[e.Row.RowIndex].Value);
LinkButton lbtnDelete = (LinkButton)e.Row.FindControl("lbtnDelete");
if (lbtnDelete != null)
{
lbtnDelete.CommandArgument = id.ToString();
lbtnDelete.Attributes.Add("onClick", "");
}
}
}
}
3,先引用System.windwos.Forms,然后在进行处理.
using System.Windows.Forms;
protected void gvNewList_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
DialogResult result = MessageBox.Show("确定要删除本行吗?", "信息提示!", MessageBoxButtons.YesNo, MessageBoxIcon.Question,MessageBoxDefaultButton.Button2,MessageBoxOptions.ServiceNotification);
if (result == DialogResult.Yes)
{
e.Cancel = false;
}
else
{
e.Cancel = true;
}
}
4,添加一个删除列
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
TableCell tc = (TableCell)e.Row.Cells[e.Row.Cells.Count - 1];
for (int i = 0; i < tc.Controls.Count; i += 2)
{
// cerco il controllo ImageButton (ho utilizzato quello)
Object o = tc.Controls[i];
if (o is ImageButton)
{
// controllo trovato!
// ora aggiungo levento js onClick per chiedere conferma allutente
ImageButton lb = (ImageButton) o;
((ImageButton)lb).Attributes.Add("onclick", @"javascript:return confirm(Attenzione: sicuro di voler cancellare?);");
}
}
}
-------------------------------------------------------------
以上方法总结
---------Template way-----------------------------------------------
Text="删除" OnClientClick=return confirm("Are you sure you want to delete this record?");>
-------------RowDeleting method------------------------------------------------
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
Response.Write("");
}
-------------RowDataBound method--------------------------------------------------------------
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
((LinkButton)e.Row.Cells[4].Controls[0]).Attributes.Add("onclick", "javascript:return confirm(确实要删除该记录吗?)");
}
