C# 网格列右对齐

Question

我正在使用下面的代码（部分代码）从网格行中打印出来。但是最后一列有金额。所以我想将最后一列对齐为右对齐。但是我得到了错误。

DataTable dt = (DataTable)ViewState["Datasource"];
DataTable newTable = dt.DefaultView.ToTable(false, "FLD_ID", "FLD_CUST_ID", "FLD_CUST_NAME", "FLD_CUST_ADDR", "FLD_AMT");
newTable.Columns["FLD_ID"].ColumnName = "PAY.ID";
newTable.Columns["FLD_CUST_ID"].ColumnName = "CUST.ID";
newTable.Columns["FLD_CUST_NAME"].ColumnName = "CUST.NAME";
newTable.Columns["FLD_CUST_ADDR"].ColumnName = "ADDRESS";               
newTable.Columns["FLD_AMT"].ColumnName = "INV.AMOUNT";

GridView PrintGrid = new GridView();
PrintGrid.DataSource = newTable;
PrintGrid.DataBind();
PrintGrid.AllowPaging = false;
PrintGrid.Columns[4].ItemStyle.HorizontalAlign = HorizontalAlign.Right;
//Got Error Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index.

请帮我解决这个问题。

Answer 1

PrintGrid.Columns[4].ItemStyle.CssClass="alignright";

然后添加 CSS

.alignright{
   text-align:right;
      }

Answer 2

这是

您问题的解决方案。

    protected void GridView1_RowDataBound(object o, GridViewRowEventArgs e)
{
    //Assumes the Price column is at index 4
    if(e.Row.RowType == DataControlRowType.DataRow)
        e.Row.Cells[4].HorizontalAlign = HorizontalAlign.Right;
}

Answer 3

在行数据绑定事件中对齐

protected void GridView_RowDataBound(object o, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
     e.Row.Cells[1].HorizontalAlign = HorizontalAlign.Right;
  }
}

Answer 4

它对我有用的唯一方法是使用

e.Row.Cell[field_position].Style.Value = "text-align: right". 

除了此代码之外，不需要更多工作。工作正常。即使一起使用，其他选项也不会生效。
