对于加载的第一个页面,如果单击命令字段,它将显示正确的DataKey值。
但是,如果我更改为结果的下一页,则在选择记录时,相应的值不正确。它似乎保留了上一页的信息。我该如何克服这个问题?
编辑:
在GridView1_SelectedIndexChanged方法中,我使用了以下内容:
// Determine the index of the selected row.
int index = GridView1.SelectedIndex;
// Display the primary key value of the selected row.
HttpContext.Current.Response.Write("The primary key value of the selected row is " + GridView1.DataKeys[index].Value.ToString() + ".<br>");
GridViewRow row = GridView1.Rows[index];
int rowindex = row.RowIndex;
HttpContext.Current.Response.Write("rowindex-> " + rowindex.ToString() + "<br>");
int ID = (int)GridView1.DataKeys[row.DataItemIndex - (GridView1.PageIndex * GridView1.PageSize)].Value;
HttpContext.Current.Response.Write("row.DataItemIndex" + ID.ToString()+"<br>");
int Userid = Convert.ToInt32(GridView1.DataKeys[index].Value);
HttpContext.Current.Response.Write("Userid" + Userid.ToString() + "<br>");
分页后我无法获得正确的值。

使用分页时,我们可以获得确切的行索引(在gridview中从0到totalrows
计算)
并且在获取datakey
时,我们需要传递当前页面的行索引。
使用下面的行获取当前页面索引并获取datakey:
// Get the correct row index since there is paging
int idx = gridViewRow.DataItemIndex - TestGridView.PageIndex * TestGridView.PageSize;

我可能会迟到。 但对于其他人,我回答这个问题。
“在使用DataKey数组之前再次重新绑定gridview”
它对我有用。 希望它也适用于其他人。

前一段时间修复过。正在使用第三方GridViewhelper类。这破坏了GridView的正常功能。
