C# DataGridView 使用
2024-10-20 11:29:05
之前咩有做个界面的东西,更没有使用过DataGirdView 这个控件。
现在本来是准备用DeV呢,结果发现我的DEV没有注册,只好暂时用这个DataGridView来替代使用了。
我现在要是设置两列多行的,一列是属性字段名称值,一列是添加了Combox,下拉表来选择对应的纹理文件路径。
经过各种搜索查询,终于基本搞定能用。
一、建了个窗体工程
给工程来个名字,叫GridViewAndControl,然后来个工具箱里的DataGridView,起来个名字叫m_CAtDataGridView,然后加了个按钮,
用来保存你选择后对应属性名称和下拉框选择项。
先说明一下,保存的时候用Hashtable,你懂的,也就是属性名称字段不能重复,否则作为key,是不能存到Hashtable中的啊。
如下图:简单。
二、上菜,代码
有三个事件,窗体加载事件,Form1_Load; 按钮保存,button_click事件;还加了一个添加序号的RowPostPaint,这个网上找到。
首先,窗体加载:
private void Form1_Load(object sender, EventArgs e)
{
DataGridViewCheckBoxColumn newColumn = new DataGridViewCheckBoxColumn();
m_CAtDataGridView.Columns.Insert(0, newColumn);
newColumn.HeaderText = "选择";
DataGridViewTextBoxColumn Texture = new DataGridViewTextBoxColumn();
Texture.HeaderText = "字段";
m_CAtDataGridView.Columns.Insert(1, Texture);
//
DataGridViewComboBoxColumn dcob = new DataGridViewComboBoxColumn();
m_CAtDataGridView.Columns.Insert(2, dcob);
dcob.HeaderText = "纹理路径";
dcob.Items.AddRange(new string[] { "Test1", "Test2", "Test3", "Test4" }); //foreach (string field in table_Field)
for (int i = 0; i < 5;i++ )
{
DataGridViewRow newrow = new DataGridViewRow();
newrow.CreateCells(m_CAtDataGridView);
newrow.Cells[2].Value = "Test2";// 设置默认值
newrow.Cells[0].Value = true;
newrow.Cells[1].Value = "t" + i.ToString();
m_CAtDataGridView.Rows.Add(newrow);
}
dcob.Selected = true;
// 不显示新添加行
m_CAtDataGridView.AllowUserToAddRows = false;
m_CAtDataGridView.AutoSize = false;
//m_CAtDataGridView.RowHeadersVisible = false;
// 行颜色变化
m_CAtDataGridView.RowsDefaultCellStyle.BackColor = Color.FromArgb(255, 90, 0);
m_CAtDataGridView.AlternatingRowsDefaultCellStyle.BackColor = Color.FromArgb(50, 205, 50);
m_CAtDataGridView.GridColor = Color.FromArgb(16, 139, 87);
}
其次,按钮保存表里的值,保存到Hashtable中。
private void button1_Click(object sender, EventArgs e)
{
Hashtable HashFieldTex = new Hashtable();
int iNum = m_CAtDataGridView.Rows.Count; try
{
for (int i = 0; i < iNum; i++)
{
string Chos = m_CAtDataGridView.Rows[i].Cells[1].Value.ToString();
string Textrue = m_CAtDataGridView.Rows[i].Cells[2].Value.ToString();
HashFieldTex.Add(Chos, Textrue);
}
}
catch (Exception ex)
{
string mes = ex.Message;
}
}
最后,给第一列添加序列号。
private void m_CAtDataGridView_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
using (SolidBrush b = new SolidBrush(m_CAtDataGridView.RowHeadersDefaultCellStyle.ForeColor))
e.Graphics.DrawString((e.RowIndex + 1).ToString(),
e.InheritedRowStyle.Font, b, e.RowBounds.Location.X, e.RowBounds.Location.Y);
}
最后效果:不美,因为没有把写给列 设置宽度大小!

m_CAtDataGridView.GridColor = Color.FromArgb(16, 139, 87);
} private void button1_Click(object sender, EventArgs e)
{
Hashtable HashFieldTex = new Hashtable();
int iNum = m_CAtDataGridView.Rows.Count; try
{
for (int i = 0; i < iNum; i++)
{
string Chos = m_CAtDataGridView.Rows[i].Cells[1].Value.ToString();
string Textrue = m_CAtDataGridView.Rows[i].Cells[2].Value.ToString();
HashFieldTex.Add(Chos, Textrue);
}
}
catch (Exception ex)
{
string mes = ex.Message;
}
} private void m_CAtDataGridView_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
using (SolidBrush b = new SolidBrush(m_CAtDataGridView.RowHeadersDefaultCellStyle.ForeColor))
e.Graphics.DrawString((e.RowIndex + 1).ToString(),
e.InheritedRowStyle.Font, b, e.RowBounds.Location.X, e.RowBounds.Location.Y);
}
}
}
新手新学,见效就笑吧!
