不要通过页面提交的方法，我的程序是本页面提交，本页显示的。

[wei123456]

使用ViewState 提交后如果ViewState为空将ViewState赋值，不为空则认为是二次提交

[liu_ff123]

不要通过页面跳转

[showrock]

按钮提交过后,visibile=false

[wei123456]

ViewState 就是本页使用的

[liu_ff123]

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{


}

private void Binder()
{
this.UltraWebGrid1.DataSourceID = "ObjectDataSource1";
this.UltraWebGrid1.DataBind();

}

protected void Button1_Click(object sender, EventArgs e)
{
LWord txtcontext = new LWord();
txtcontext.TextContent = this.TextArea1.Value;
(new Services()).send_word(txtcontext);
this.TextArea1.Value = "";
Binder();
}
}

各位怎么实现

[volezbin]

完成操作后,加个Response.Redirect重新定向回本页

[truecoffeefox]

清空viewstate跳到另一个页面再转回去呗

这样跳来跳去肯定很累吧！速度应该不快

加个验证码

[wei123456]

protected void Button1_Click(object sender, EventArgs e)
{
if ( ViewState["Submit"] != null )
{
LWord txtcontext = new LWord();
txtcontext.TextContent = this.TextArea1.Value;
(new Services()).send_word(txtcontext);
this.TextArea1.Value = "";
Binder();
ViewState["Submit"] = "1";
}
}

[liu_ff123]

protected void Button1_Click(object sender, EventArgs e)
{
if ( ViewState["Submit"] != null )
{
LWord txtcontext = new LWord();
txtcontext.TextContent = this.TextArea1.Value;
(new Services()).send_word(txtcontext);
this.TextArea1.Value = "";
Binder();
ViewState["Submit"] = "1";
}
}


这样好像不行吧

mark下

[volezbin]

如果是按钮触发事件,做一个Response.Write("<script language='javascript'>alert('操作成功');history.go(-1);</script>");
要不就Response.Redirect
这是最简单的两个方法.
如果你觉得不够好,建议采取楼上说的加验证码,或者做viewstate处理
