从 Button Click 事件崩溃的 GridView 更新

Question

在 ButtonClick 事件上填充 gridview 后，我面对数组异常。当从页面加载触发时，相同的源工作得很好。在 Whosebug 上找不到类似的 post。请指教。谢谢

代码：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells[0].Attributes["width"] = "30px";
    e.Row.Cells[1].Attributes["width"] = "40px";   -> CRASHES AT INDEX 1
    e.Row.Cells[2].Attributes["width"] = "40px";
    e.Row.Cells[3].Attributes["width"] = "50px";
    e.Row.Cells[4].Attributes["width"] = "50px";
    e.Row.Cells[5].Attributes["width"] = "100px";
    e.Row.Cells[5].HorizontalAlign = HorizontalAlign.Left;
}

<asp:GridView ID="GridView1" runat="server" CellPadding="4"
    ForeColor="Black" GridLines="Horizontal" Width="100%" ShowHeader="true" 
    EmptyDataText="No Records found.!" 
    RowStyle-Wrap="true" AllowPaging="true" PageSize="5"
    OnPageIndexChanging="gridView_PageIndexChanging"
    OnRowDataBound="GridView1_RowDataBound"         
    style="table-layout:fixed; word-wrap:break-word; margin-left: 0px;" >

您应该检查它是什么类型的行。我正在检查 DataRow，但您可能只想对 Header 执行此操作。

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Cells[0].Attributes["width"] = "30px";
        e.Row.Cells[1].Attributes["width"] = "40px";   -> CRASHES AT INDEX 1
        e.Row.Cells[2].Attributes["width"] = "40px";
        e.Row.Cells[3].Attributes["width"] = "50px";
        e.Row.Cells[4].Attributes["width"] = "50px";
        e.Row.Cells[5].Attributes["width"] = "100px";
        e.Row.Cells[5].HorizontalAlign = HorizontalAlign.Left;
    }
}
