Question

目前，我在数据库中打印的关于交易摘要的文件如下所示：

enter image description here

正如您在上面的图像中看到的那样，描述列上的文本没有被系统完全读取，因为没有足够的空间来读取所有文本，因此系统会根据需要剪切文本。这是我的数据库看起来像数据库摘要中数据库的打印文件：

enter image description here

我的问题是：如何使描述栏更大更长，以便其上的文字可以完全读取，或者当我们在其上键入文本时如何使其他列适合？

示例：“数量”列的列越长越大，我希望数量列适合数字“10”的右侧和左侧。

有任何帮助吗？谢谢

编辑：抱歉，忘了复制粘贴我用于此系统的代码：p

这是我用于打印文件的代码：

private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
        {
            try
            {
                //Set the left margin
                int iLeftMargin = e.MarginBounds.Left;

                //Set the top margin
                int iTopMargin = e.MarginBounds.Top;

                //Whether more pages have to print or not
                bool bMorePagesToPrint = false;

                int iTmpWidth = 0;

                int width = 500;

                int height = 90;

                //For the first page to print set the cell width and header height
                if (bFirstPage)
                {
                    foreach (DataGridViewColumn GridCol in dataGridView1.Columns)
                    {
                        iTmpWidth = (int)(Math.Floor((double)((double)GridCol.Width / (double)iTotalWidth * (double)iTotalWidth * ((double)e.MarginBounds.Width / (double)iTotalWidth))));

                        iHeaderHeight = (int)(e.Graphics.MeasureString(GridCol.HeaderText, GridCol.InheritedStyle.Font, iTmpWidth).Height) + 11;

                        // Save width and height of headres
                        arrColumnLefts.Add(iLeftMargin);
                        arrColumnWidths.Add(iTmpWidth);

Answer 1

一个选项是指定每列的宽度：

dataGridView1.Columns["Quantity"].Width = 50;
dataGridView1.Columns["Description"].Width = 250;

另一种选择是告诉DataGridView自动调整所有列的大小：

dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;

Answer 2

您总是可以将cssClass分配给网格视图并让它自动调整吗？

这是我通常使用的简单的东西：

        .Gridview 
    {
        border-collapse: collapse;
        width:100%;
    }
        .Gridview tr th
        {
            background-color: #3c454f;
            color: #ffffff;
            padding: 10px 5px 10px 5px;
            border: 1px solid #cccccc;
            font-family: 'Calibri';
            font-size: 15px;
            font-weight: normal;
            text-transform:capitalize;
        }
        /**/
        .Gridview tr:nth-child(2n+2)
        {
            background-color: #f3f4f5;
        }

        .Gridview tr:nth-child(2n+1) td
        {
            background-color: #d6dadf;
            color: #454545;
        }
        .Gridview tr td
        {
            padding: 5px 10px 5px 10px;
            color: #454545;
            font-family: Calibri;
            font-size: 12px;
            border: 1px solid #cccccc;
            vertical-align: middle;
        }

额外奖励：使您的gridview看起来也很酷。：）

希望它有所帮助。祝你好运。
