我有一个通过我的 SQL 数据阅读器填充的网格视图

网格视图：

<asp:GridView ID="gridviewALL" runat="server" OnItemDataBound="Search_ItemDataBound">
</asp:GridView>

SQL 数据阅读器：

SqlCommand cmd = new SqlCommand("SELECT en.dpCreatedDT AS 'Time Received', en.enStatusCH AS 'Status', en.enNotificationNoNI AS 'LSBUD Ref', cm.cmpersonfirstch AS 'First Name', cm.cmPersonLastCH AS 'Last Name', cm.cmcompanynamech AS 'Company' FROM dp_enquiry en JOIN dp_caller_master cm ON (en.encmcallerkeyfk = cm.cmCallerKeyNI) WHERE en.ennotificationnoni = @JobnoALL", conn);
        try
        {
            SqlParameter search = new SqlParameter();
            search.ParameterName = "@JobnoALL";
            search.Value = JobnoALL.Text.Trim();
            cmd.Parameters.Add(search);
            SqlDataReader dr = cmd.ExecuteReader();
            DataTable dt = new DataTable();
            dt.Load(dr);
            gridviewALL.DataSource = dt;
            gridviewALL.DataBind();
        }

当文本等于一个值时，我正在尝试更改网格视图中单元格的格式，我之前使用列表视图完成了此操作，但 Gridview 步骤似乎不同。我有以下似乎没有任何建议？

private void Search_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
    string CurrentColumn = e.Item.Cells[1].Text;
    if (CurrentColumn == "PROC")
    {
        e.Item.Cells[1].Text = "Creating PDF";
    }
    else if (CurrentColumn == "CLOS")
    {
        e.Item.Cells[1].Text = "Complete";
        e.Item.Cells[1].ForeColor = System.Drawing.Color.Green;
    }
}

它必须正在读取标题，您需要检查它是否为DataRow：-

 if (e.Row.RowType == DataControlRowType.DataRow)
 {
    string CurrentColumn = e.Item.Cells[1].Text;
    //your code goes here..
 }

另外，我建议您使用DataBinder.Eval方法来避免对单元格索引进行硬编码，因为如果列的顺序发生变化，它可能会导致错误。

string CurrentColumn = DataBinder.Eval(e.Row.DataItem, "yourColumnName").ToString();

更新：

刚刚注意到您正在使用ItemDataBoundwhich is an event for DataGridand not Gridview。改用RowDataBound事件：-

<asp:GridView ID="gridviewALL" runat="server" OnRowDataBound="gridviewALL_RowDataBound">
</asp:GridView>

您的 rowDataBound 事件应如下所示：-

protected void gridviewALL_RowDataBound(object sender, GridViewRowEventArgs e)
{
    //your code here
}
