的GridView - 集列的寬度在後面的代碼（的AutoGenerateColumns = 「真」）

Question

我的GridView：

<asp:GridView ID="GridView1" runat="server" 
    OnRowDataBound="GridView1_RowDataBound" 
    AutoGenerateColumns="true" 
    DataKeyNames="Role_id"> 
</asp:GridView> 

在後面的代碼：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.Header) 
    { 
     //e.Row.Cells[2].Width = 120;      // isn't working.... 
    } 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     e.Row.Cells[2].Width = new Unit(120);    // isn't working.... 
     TableCell cell = e.Row.Cells[2]; 
     cell.HorizontalAlign = HorizontalAlign.Right;   //**** does work! 
     cell.BackColor = Color.LightGray;      //**** does work! 
     //cell.Width = 120;        // isn't working.... 
     //e.Row.Cells[2].Width = new Unit("120px") ;  // isn't working.... 
     //e.Row.Cells[2].CssClass = "myGV_Cell_Width"; // isn't working.... 
    } 
} 

GridView控件被成功填充。
請注意，我可以設置列的對齊和背景顏色，但不是它的寬度。
我嘗試了許多解決方案，但都沒有工作。
它總是將列的大小調整爲最長的內容。
它可以完成...？

Answer 1

我能夠與RowCreated事件做它來設置列寬，但我不得不設置網格的寬度和也將網格設置爲表格佈局：固定

<asp:GridView ID="GridView1" runat="server" 
    style="table-layout:fixed;" Width="1000px" 
    OnRowCreated = "GridView1_RowCreated" 
    OnRowDataBound="GridView1_RowDataBound" 
    AutoGenerateColumns="true" 
    DataKeyNames="Role_id"> 
</asp:GridView> 

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e) 
{ 

e.Row.Cells[0].Width = New Unit("220px"); 

}

ASP：GridView控件呈現到HTML表，所以你只需要使用CSS

th, td { 
    width: 120px; 
}
