我的阙。在asp.net 3tire [英] My que. in asp.net 3tire

问题描述

我的错误是=>

索引超出范围。必须是非负数且小于集合的大小。

参数名称：index



删除数据中的此错误=>

My error is =>
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

this error in Delete data=>

protected void lbtnDelete_Click(object sender, EventArgs e)
{
    var objPerson = new Person();
    GridViewRow gr = (GridViewRow)((Control)sender).NamingContainer;
    objPerson.PersonId= Convert.ToInt32(dgvPerson.DataKeys[gr.RowIndex].Values["PersonId"]);
    PersonBLL.Delete(objPerson);
    LoadPersonGrid();

}

推荐答案

objPerson.PersonId = Convert.ToInt32 （dgvPerson.DataKeys [gr.RowIndex]



检查 rowindex 值。您没有该行的 DateKeys 。

objPerson.PersonId= Convert.ToInt32(dgvPerson.DataKeys[gr.RowIndex]

Check the rowindex value. You do not have DateKeys for that row.
