将文本添加到DataGridView行标题

Question

C#允许您将一个String添加到DataGridView中的RowHeader吗？如果是这样,它是如何完成的？

我正在写一个Windows表单来显示到目前为止的年度客户付款数据.

ColumnHeaders显示1月,2月,3月等...而不是有一个DateTime.Now.Year的空白列我想把它放在RowHeader中,使其从实际的支付数据中脱颖而出.

Answer 1

private void dtgworkingdays_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
    this.FillRecordNo();
}


private void FillRecordNo()
{
    for (int i = 0; i < this.dtworkingdays.Rows.Count; i++)
    {
        this.dtgworkingdays.Rows[i].HeaderCell.Value = (i + 1).ToString();
    }
}

Answer 2

datagridview1.Rows[0].HeaderCell.Value = "Your text";

有用.

Answer 3

您不必使用RowValidated事件,这只是我用于一个小测试应用程序的事件,以确保它有效,但这会将行(而不是列)标题文本设置为您指定的任何年份.

实际上,在CellFormatting事件中可能会更好.

    private void dataGridView_RowValidated(object sender, DataGridViewCellEventArgs e)
    {
        DataGridView gridView = sender as DataGridView;

        if (null != gridView)
        {
            gridView.Rows[e.RowIndex].HeaderCell.Value = "2009";
        }
    }

编辑:这是我使用的整个TestForm,尽可能简单地演示解决方案.确保您的RowHeadersWidth足够宽以显示文本.

using System.Windows.Forms;

namespace DataGridViewTest
{
    public class GridTest : Form
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private IContainer components;

        private DataGridView dataGridView1;
        private DataGridViewTextBoxColumn Month;

        public GridTest()
        {
            InitializeComponent();
        }

        /// <summary>
        /// Clean up any resources being used.

        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        private void dataGridView_RowValidated(object sender, DataGridViewCellEventArgs e)
        {
            DataGridView gridView = sender as DataGridView;

            if (null != gridView)
            {
                gridView.Rows[e.RowIndex].HeaderCell.Value = "2009";

Answer 4

这是因为你的第一列(Rows Header列)宽度!增加它的宽度然后你可以看到它的价值!你可以使用这个命令:

dgv1.RowHeadersWidthSizeMode = DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders;

(注意:你必须先设定dgv1.RowHeadersVisible = true;)

Answer 5

是的。首先，挂钩添加的列事件：

this.dataGridView1.ColumnAdded += new DataGridViewColumnEventHandler(dataGridView1_ColumnAdded);

然后，在您的事件处理程序中，只需附加您想要的文本：

private void dataGridView1_ColumnAdded(object sender, DataGridViewColumnEventArgs e)
{
    e.Column.HeaderText += additionalHeaderText;
}
