在rowdatabound事件中设置Gridview的列宽.

Question

我有以下代码.我没有在gridview中定义任何边界字段.我正在使用我的aspx.cs文件中的sql查询来检索数据.是否可以调整每列0,1,2的宽度？我有什么办法可以研究吗？我尝试了很多方法,但它仍然无法正常工作.请帮忙!

<asp:GridView ID="surgicalGridView" runat="server"
    CaptionAlign="Top" HorizontalAlign="Justify" 
    DataKeyNames="id" onselectedindexchanged="surgicalGridView_SelectedIndexChanged"
    ToolTip="Excel File Download Tool" CellPadding="4" ForeColor="#333333" 
    GridLines="None" Width="854px">

     <RowStyle BackColor="#E3EAEB" />
       <Columns>
       <asp:CommandField ShowSelectButton="True" SelectText="Download" 
               ControlStyle-ForeColor="Blue">
<ControlStyle ForeColor="Blue"></ControlStyle>
           </asp:CommandField>
       </Columns>
     <FooterStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
     <PagerStyle BackColor="#666666" ForeColor="White" HorizontalAlign="Center" />
     <SelectedRowStyle BackColor="#C5BBAF" Font-Bold="True" ForeColor="#333333" />
     <HeaderStyle   BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
     <EditRowStyle BackColor="#7C6F57" />
     <AlternatingRowStyle BackColor="White" />
        <SortedAscendingCellStyle BackColor="#F8FAFA" />
        <SortedAscendingHeaderStyle BackColor="#246B61" />
        <SortedDescendingCellStyle BackColor="#D4DFE1" />
        <SortedDescendingHeaderStyle BackColor="#15524A" />
    </asp:GridView>
    <br />

你可以在OnRowDataBound事件发生时这样做gridview.

protected void surgicalGridView_RowDataBound(object o, GridViewRowEventArgs e)
{           
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
         e.Row.Cells[0].Width = new Unit("200px");
         e.Row.Cells[1].Width = new Unit("400px");
         // and so on
    } 
}

将此添加到您的Gridview标记

<asp:GridView ...............................
        onrowdatabound="surgicalGridView_RowDataBound">    // just add this event and execute the above code
 </asp:GridView>
