在ASP.NET中以编程方式设置gridview列宽 [英] Set gridview column width programmatically in asp.net

问题描述

需要以编程方式在asp.net中设置gridview的列宽。
**自动生成的列（即AutogenerateColumns = true）。

Need to set the column width of a gridview in asp.net programmatically. ** Autogenerated Columns (i.e., AutogenerateColumns = "true").

我尝试了以下操作；

protected void gv_RowCreated(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells[2].Width = Unit.Pixel(200);
}

但没有用。

推荐答案

这是我在ASPX文件上的 GridView1

This is my GridView1 on aspx file

<asp:GridView ID="GridView1" runat="server" AllowSorting="True" 
Font-Size="Small" Width="800px" OnRowDataBound="GridView1_RowDataBound" > 

        <Columns>
                <asp:CommandField SelectText="Seç" ShowSelectButton="True"/>
        </Columns>

</asp:GridView>

这是我在代码隐藏区中以编程方式设置GridView列宽的地方，实际上是关于设置单元格的宽度但是它控制列的宽度，所以这是一种方法。您可以看到我没有 AutogenicColumns = True ，尽管我认为这并不重要，因为 GridView.RowDataBound 当数据行绑定到数据时发生。

This is where I set my GridView's column width programmatically in codebehind.It is actually about setting the cell's width but it controls the column width so this is a way.As you can see I do not have AutogeneratedColumns="True", though I do not think that would matter because GridView.RowDataBound occurs when a data row is bound to data.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{ 
     e.Row.Cells[1].Width = 1;
     e.Row.Cells[0].Width = 1;
     e.Row.Cells[4].Width = 75;
     e.Row.Cells[5].Width = 1;                
}
