Question

我需要在gridview中单击自动生成删除按钮时显示确认消息。

我的代码在这里

 AllowPaging="true" PageSize="10" OnClientClick="return confirm('Are you sure you want to delete this event?');"></asp:GridView>

 protected void grdFraction_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        int catid = int.Parse(grdFraction.DataKeys[e.RowIndex].Value.ToString());
        var delQuery = "delete from nano_WasteFraction where FID='" + catid + "'";
        SqlHelper.ExecuteNonQuery(GlobalSettings.DbDSN, CommandType.Text, delQuery);
        GridBind();
    }

我只是在gridviw中添加OnClientClick。但是它没有工作。任何一个帮助吗？

Answer 1

您是否尝试在删除按钮标记上使用以下代码？

OnClientClick="return confirm('Are you sure you want to delete this?');"

它对我很有用。

Answer 2

      <script language="javascript" type="text/javascript">
         function DisplayCancelMessage() {
             var value = confirm("Are You Sure, You Want to  delete this event?");
             if (value) {
                 return true;
             }
             else {
                 return false;
             }
         } 
     </script>


     And Add OnClientClick Property in to the delete button 

        OnClientClick="return DisplayCancelMessage();"

尝试这样，

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton l = (LinkButton)e.Row.FindControl("LinkButton1"); 
l.Attributes.Add("onclick", "javascript:return " +
"confirm('Are you sure you want to delete this record " +
DataBinder.Eval(e.Row.DataItem, "CategoryID") + "')"); 
}
}

删除asp.net gridview中的确认自动生成删除按钮单击
