Question

DataView dv = ds.Tables["Unit"].DefaultView;
dv.RowFilter = SqlWhere;
dv.Sort = SortList.SelectedValue.ToString();
PagedDataSource page = new PagedDataSource();
page.DataSource = dv;
page.AllowPaging = true;
page.PageSize = Int32.Parse(ResultList.SelectedValue);
page.CurrentPageIndex = CurrentPage;
lblCurrentPage.Text = "Page: " + (CurrentPage + 1).ToString() + " of " +
                                                        page.PageCount.ToString();
// Disable Prev or Next buttons if necessary
cmdPrev.Enabled = !page.IsFirstPage;
cmdNext.Enabled = !page.IsLastPage;
invList.DataSource = page;
invList.DataBind();
public int CurrentPage
{
    get
    {
        // look for current page in ViewState
        object o = this.ViewState["_CurrentPage"];
        if (o == null)
            return 0; // default page index of 0
        else
            return (int)o;
    }

    set
    {
        this.ViewState["_CurrentPage"] = value;
    }
}

但它现在在invList.DataBind();

中显示如下错误

Index 4 is either negative or above rows count.

任何人都可以帮忙吗？

Answer 1

看起来invList.DataBind正在设置的绑定是指诸如dv之类的视图。这是猜测，因为它会在您的代码中的其他位置。

对于要在简单控件中显示的多行表中的数据，绑定需要知道要使用哪一行，此错误表示确定行正在返回的任何内容＆＃34;索引4＆＃34; （第5行...索引从0开始），表中有4行或更少的行。

检查行导航，尤其是在更改基础表的内容之后，确保其当前行设置为有效数字。

索引1为负数或高于行数
