Sorting GridView排序，但链接按钮'；Commands的参数不是

gridview显示精细，按任一列进行排序效果很好。但是，单击链接按钮时，返回的CommandArgument值不正确。这就好像CommandArgument绑定到了行，并且没有得到排序

i、 e.分类前

Text   Command
abc    A
aaa    B
aab    C

排序后

Text   Command
aaa    A
aab    B
abc    C

单击aaa将返回“A”作为参数，而不是B

aspx文件中的GridView定义如下：

<asp:GridView ID="GridView1" runat="server"
              AllowSorting="True"
              AutoGenerateColumns="False"
              EmptyDataText="No Results to Display"  
              GridLines="None" 
              onsorting="GridView1_Sorting" >
    <Columns>
        <asp:TemplateField HeaderText="File Name" SortExpression="Path">
            <ItemTemplate>
                <asp:LinkButton ID="linkbutton1" runat="server" Text='<%# Eval("Title") %>' OnCommand="LinkButton_Click" CommandArgument='<%# Bind("Path") %>' ></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField HeaderText="Document Type" DataField="DocumentCategory (Text)" SortExpression="DocumentCategory (Text)" />
    </Columns>
</asp:GridView>

我的分类方法是

protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
    string sortDir = "ASC";
    if (ViewState["SortDirection"] == null)
        ViewState["SortDirection"] = "ASC";

    if (ViewState["SortDirection"].ToString() == "ASC")
    {
        sortDir = "DESC";
        ViewState["SortDirection"] = "DESC";
    }
    else
    {
        ViewState["SortDirection"] = "ASC";
    }

    DataTable dt = (DataTable)ViewState["GridView1_DataSource"];
    DataView dv = new DataView(dt);
    dv.Sort = e.SortExpression + " " + sortDir;
    GridView1.DataSource = dv;
    GridView1.DataBind();
}

通过GridView1\u排序进行排序时，会先处理页面加载，然后再处理GridView1\u排序。因此，数据显示正确。单击LinkButton时，页面加载将在GridView1\uuuu行命令之前处理。通常，Gridview的数据绑定在页面加载中，因此数据现在处于原始顺序。要更正，请将排序也放在页面加载数据绑定中

如果（dt.Rows.Count>0）

{

数据视图dv=新数据视图（dt）

}

我认为您无法对空数据表进行排序

您可以通过调试并在排序和页面加载中添加断点来轻松验证这一点

我找到了解决办法。这对我有用。试试这个

 protected void LinkButton_Click(object sender, EventArgs e)
 {
    sortExpr = "Path";
    GridView1_Sorting(null, null);
 } 

改变这一点：

string sortExpr;
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
      String sortExpression = null;
        if (sortExpr == null)
        {
            sortExpression = e.SortExpression;

        }
        else
        {
            sortExpression = sortExpr;
        }

    Session["SortExpression"] = sortExpression;

        if (Session["SortDirection"] != null && Session["SortDirection"].ToString() ==    SortDirection.Descending.ToString())
        {
            Session["SortDirection"] = SortDirection.Ascending;
            SortGridview(sortExpression, "ASC");
        }
        else
        {
            Session["SortDirection"] = SortDirection.Descending;
            SortGridview(sortExpression, "DESC");
        }
 }

 private void SortGridview(string sortExpression, string Direction)
    {
        DataView dv = null;
        DataTable dt = GridView1.DataSource as DataTable;
        dv = new DataView(dt);
        dv.Sort = sortExpression + " " + Direction;
        GridView1.DataSource = dv;
        GridView1.DataBind();

    }

你找到解决办法了吗？我有同样的问题，我有同样的问题。有人吗？甚至更好——根本不更新加载页面上的数据源。在处理事件后执行更新。

 protected void LinkButton_Click(object sender, EventArgs e)
 {
    sortExpr = "Path";
    GridView1_Sorting(null, null);
 } 

string sortExpr;
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
      String sortExpression = null;
        if (sortExpr == null)
        {
            sortExpression = e.SortExpression;

        }
        else
        {
            sortExpression = sortExpr;
        }

    Session["SortExpression"] = sortExpression;

        if (Session["SortDirection"] != null && Session["SortDirection"].ToString() ==    SortDirection.Descending.ToString())
        {
            Session["SortDirection"] = SortDirection.Ascending;
            SortGridview(sortExpression, "ASC");
        }
        else
        {
            Session["SortDirection"] = SortDirection.Descending;
            SortGridview(sortExpression, "DESC");
        }
 }

 private void SortGridview(string sortExpression, string Direction)
    {
        DataView dv = null;
        DataTable dt = GridView1.DataSource as DataTable;
        dv = new DataView(dt);
        dv.Sort = sortExpression + " " + Direction;
        GridView1.DataSource = dv;
        GridView1.DataBind();

    }
