设置gridview列的宽度？

在下面的例子中，我用一些数据填充gridview。一切都很好，但我不知道如何设置列宽。 gridview没有任何设置列，所以我不能使用ItemStyle-Width。我尝试使用GridViewClicks_RowDataBound，但e.Row.Cells[i].Width不起作用，即使e.Row.Cells[i].Height确实有效。设置gridview列的宽度？

我也尝试在page_load中设置column.ItemStyle.Width，但也不起作用。

基本上，我需要设置gridview的列宽而不在标记中添加列。

任何帮助表示赞赏。

谢谢。

这里的标记：

      width: calc(100% - 480px); 
      padding: 0 0 17px 0; 
     } 
    </style> 
    <script type="text/javascript"> 

     $('#dvGridWidth').width($('#dvScreenWidth').width()); 

    </script>

可能是重复的，看看这个：http://stackoverflow.com/a/2740947/5418068 – PJS

它不是重复的。这正是我以前测试过的代码无效的代码。我在我的问题中提到了这一点，并包含了完全相同问题中的代码。 – rbhat

你可以添加一个CSS类（房产），以你的GridView，并在浏览器中的GridView呈现为一个表，你可以设计/根据需要指定表格。

添加CSS样式说：

table{ 
    border: 1px solid black; 
    table-layout: fixed; 
    width: 200px; 
} 

th, td { 
    border: 1px solid black; 
    width: 100px; 
}

@Runtime使用的GridView的RowDataBound事件改变宽度： EX：

protected void DataGrid_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    e.Row.Cells[0].Width = new Unit("width-in-px"); 
    e.Row.Cells[1].Width = new Unit("width-in-px"); 
    ...... 
}

你也可以算在GridView列并循环上面的宽度相同

感谢您的回复。 200px的宽度是什么？我刚刚添加了这个css，并将'RowDataBound'中的'e.Row.Cells [i] .Width'改为400px，宽度设置为400px。 – rbhat

但是，如果我删除它们中的任何一个（您发布的css或'RowDataBound'中的'e.Row.Cells [i] .Width'，并且它不能正确显示。似乎它需要两个，但我不是确定在哪里可以看到来自CSS的200px – rbhat

就好像CSS中的'width'值无关紧要，但该属性和'table-layout'需要在那里，所以'e.Row.Cells [i ] .Width' works。Does that sound sound？ – rbhat
