我得到“错误=索引超出范围".必须为非负数并且小于集合的大小.参数名称:“索引". [英] I get "error=Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index".

问题描述

protected void gdvErrorlog_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        try
        {
            ErrorLogDetails delerror = new ErrorLogDetails();
            GridViewRow Row = (GridViewRow)gdvErrorlog.Rows[e.RowIndex];
            ErrorId = Convert.ToInt32(gdvErrorlog.DataKeys[e.RowIndex].Values["ErrorId"]);
            EID = Convert.ToInt32(ErrorId.ToString());
            delerror.UserName = username;
            delerror.ErrorID = EID;
            delerror.delerror();
            gdvErrorlog.EditIndex = -1;
            LoadErrorDetails();
            
        }
        catch(Exception ex)
        {
            
        }
    }

推荐答案

您需要更详细地了解它-e.RowIndex似乎为负(表示没有这样的行)或引用已经删除的行.
在事件处理程序的第一行上放置一个断点，看看它何时被触发.值是负数吗?单个删除操作是否会触发多个命令?

You need to look at it in a bit more detail - it would appear that e.RowIndex is either negative (indicating no such row) or referencing an already deleted row.
Put a break point on the first line of the event handler, and see when it get fired. Is the value negative? Does it get fired more than one for a single delete operation?

请检查错误发生在哪一行.并检查e.RowIndex的值是什么.我认为它是-1.

plesase check on which line is error coming. and check that what is the value of e.RowIndex. i think it is -1.

首先，您需要检查数据是否在表中...有时是空表，它显示为上面的错误.

first you need to check whether that data is in table or not...sometimes for empty table, it displays like the above error.
