索引超出范围.必须为非负数，且小于删除行时的值 [英] index was out of range. must be non-negative and less than while deleting a row

问题描述

protected void rad_grid_ItemDeleted(object sender, GridDeletedEventArgs e)
    {        
            if (e.Exception != null)
            {
                e.ExceptionHandled = true;

                DisplayMessage(true, "customer" + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["CustomerID"] + "cannot be deleted:reason is" + e.Exception.Message);
            }
            else
            {
                DisplayMessage(false, "customer" + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["CustomerID"] + "deleted");
            }
        }

我正在使用radgrid control

推荐答案

尝试调试并逐步查看源代码以获取确切的错误.

在OwnerTableView中，没有任何行具有datakey e.Item.ItemIndex值.

Try debugging and stepping through your source code to get to the exact error.

In all probability, there is no row in OwnerTableView with datakey e.Item.ItemIndex value.

e.Item.OwnerTableView.DataKeyValues [e.Item.ItemIndex] ["CustomerID"]引发错误.

e.Item.OwnerTableView.DataKeyValues 在索引 e.Item.ItemIndex
上没有元素
快乐编码

Hi,

e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["CustomerID"] is throwing the error.

e.Item.OwnerTableView.DataKeyValues has no element at index e.Item.ItemIndex

Happy Coding

我已经回答了相同的问题，但是它在gridview上，我正在向您提供该问题链接，我希望它可以正常工作.

我收到错误=索引已出范围之内.必须为非负数且小于集合的大小.参数名称:index. [

i have answered the same question but it was on gridview i am giving you that question link i hope it will work.

I get "error=Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index".[^]
