有关gridview数据行删除弹出对话框确认的问题。

sura_99332 2011-01-25 11:05:17

项目需求有变更，要求在删除某一行数据时必须弹出对话框确认。

代码如下，请高手指教

protected void DG_GYSXX_RowDeleting(object sender, GridViewDeleteEventArgs e)
{

try
{
int index = Convert.ToInt32(e.RowIndex);
string deptid = DG_GYSXX.Rows[index].Cells[2].Text;
DeleteGYSXX(deptid);
Label_msg.Text = "删除成功";
}
catch (Exception ex)
{
throw (ex);
}
}

private void DeleteGYSXX(string deptid)
{
try
{
string deptid1 = deptid;
string valueList = deptid1;
myweb.EXEC_Proc4(BasicCode.DEL_DEPARTAD_N, userid, ref op, ref valueList);
}

catch (Exception ex)
{
throw (ex);
}

}

双击GridView的OnRowDataBound事件；在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示： 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?')"); } } }

删除前弹出提示对话框，点确定删除，取消就取消

你到底是想在删除前弹出确信对话框, 还是要在删除后弹出"删除操作成功!"的提示?

针对有click事件的控件而言：
OnClientClick="javascript:return confirm('是否删除数据？')"
用这个是否可行呢？

有时后用的时候执行了但有的时候它不执行也就是说不管你怎么点击怎么选择总是会执行click事件

唉！不知道怎么回事

lb.attributes.Add("onclick","javascript:confirm()");

楼上各位抱歉可能我表述有问题

我想在数据集里删除某一行，而不是单独的删除某一行

这列改为模版列
触发事件为RowCommand
定义LinkButton的CommandName属性与CommandArgument属性OnClientClick属性，比如这样：
CommandName="delete" CommandArgument='<%# Eval("id") %>'
OnClientClick="return confirm('确认删除吗？')">
后台调用：
……
[/Quote]
e.CCommandName=="delete"应该为
e.CommandName=="delete" 手打代码多了个C

string id=e.CommandArgument.ToString();

LinkButton 列改为模板列，

OnClientClick="javascript:return confirm('是否删除数据？')"

然后调用你的删除成功方法

这个就可以实现了。只需要在你的删除按钮上加个属性：OnClientClick="javascript:return confirm('是否删除数据？')"就行了。
