asp.net c# detailview how to set column width

Question

I have a problem with setting column width to the detailview. Tried different options like headerstyle with and fieldstyle width. But none of them seems to work.

Answer 1

使用FieldHeaderStyle-Width =“400px”来控制第一个标题列的宽度。

Answer 2

Plz Try it.

<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" 
        CellPadding="4" DataKeyNames="C_id" DataSourceID="EntityDataSource1" 
        ForeColor="Blue" Height="100px" Width="100%" AllowPaging="True">
        <AlternatingRowStyle BackColor="White" ForeColor="Red" />
        <CommandRowStyle BackColor="Blue" Font-Bold="True" />
        <EditRowStyle BackColor="#999999" />
        <FieldHeaderStyle BackColor="#E9ECF1" Font-Bold="True" Width="40%"/>
