动态列宽

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width属性那里，所以我想有GridView控件侧的选择，但即使是在数据绑定也一样，没有列...

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

问题：如何设置列宽在我的网格

ASP：

<asp:Panel id="Panel1" runat="server" ScrollBars="Auto" style="width:990px; border-style: outset; border-width: 4px;"> 
    <asp:Label ID="ERROR" runat="server"></asp:Label> 
    <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" 
     SelectMethod="GetReport" TypeName="SQF.SQF">

如果你总是希望相同的宽度，我会用CSS做。你可以这样说：

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

而且在CSS：

.wide { width: 400px; } 

如果你设置的项目风格的宽度，即CSS ID在HTML重复每一个细胞都在此列，这至少它的标记少。

如果您使用自动生成的列，那么实际列集合是空的，你需要连接到RowDataBound事件是这样的：

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

在你的GridView标记添加OnRowDataBound="GridView1_RowDataBound"
