Question

protected void GridView1_DataBound(object sender, EventArgs e)
{
    GridView1.Columns[0].ItemStyle.Width = 400;

  <asp:GridView ID="GridView1" runat="server" 
        DataSourceID="ObjectDataSource1"

ObjectDataSource1返回数据表，但我找不到任何宽度属性，所以我猜有GridView端选项，但即使在数据绑定上也没有列......

protected void GridView1_DataBound(object sender, EventArgs e)
{
    if (GridView1.Columns.Count!=0)
        GridView1.Columns[0].ItemStyle.Width = 800;

如果你总是想要相同的宽度，我会用CSS做。你可以这样做：

GridView1.Columns[0].ItemCssClass = "wide";

在CSS中：

.wide { width: 400px; }

如果你在项目样式上设置宽度，那么在html中为该列中的每个单元格重复该css id，这样至少可以减少标记。

如果您正在使用自动生成的列，那么实际的列集合是空的，您需要连接到RowDataBound事件，如下所示：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  e.Row.Cells[0].CssClass = "wide";
}

在GridView标记中添加OnRowDataBound="GridView1_RowDataBound"

动态列宽
