建立了一个project: temp,添加了一个datagridview1
添加了一个类: design.cs打算:在design.cs里设置datagridview1的表格样式(行数、列数、列宽、行高......)namespace temp
{
class design
{
(该怎么写呢?)
}
}
添加了一个类: design.cs打算:在design.cs里设置datagridview1的表格样式(行数、列数、列宽、行高......)namespace temp

public partial class Form1 : Form

public Form1()

InitializeComponent();
} private void Form1_Load(object sender, EventArgs e)
{
这里该怎么写呢?
}
}
}
Design.cs的代码:
namespace temp
{
class design
{
这里该怎么写呢?
}
}
{
dgv = new DataGridView();
dgv.Location = new Point(0, 0);
dgv.Size = new Size(300, 200);
this.Controls.Add(dgv);
Design d = new Design(this.dgv);
} class Design
{
DataGridView dgv = null;
public Design(DataGridView _dgv)
{
dgv = _dgv;
func();
} public void func()
{
if (dgv == null)
return;
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
}
}
{
DataGridView dgv = null;
public Design(DataGridView _dgv)
{
dgv = _dgv;
func();
} public void func()
{
if (dgv == null)
return;
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
}
}
{
DataGridView dgv = null;
public Design(DataGridView _dgv)
{
dgv = _dgv;
func();
} public void func()
{
if (dgv == null)
return;
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
dgv.Columns.Add("1", "1");
}
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
} private void Form1_Load(object sender, EventArgs e)
{
} private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
if (radioButton1.Checked)
{
class_demo.Style.GridStyle.GridStyle_01();
}
else
{
flex.Clear();
}
} private void radioButton2_CheckedChanged(object sender, EventArgs e)
{
if (radioButton2.Checked)
{
class_demo.Style.GridStyle.GridStyle_02();
}
else
{
flex.Clear();
}
} private void radioButton3_CheckedChanged(object sender, EventArgs e)
{
if (radioButton3.Checked)
{
class_demo.Style.GridStyle.GridStyle_03();
}
else
{
flex.Clear();
}
}
}
}
GridStyle.cs的代码:
namespace class_demo.Style
{
class GridStyle
{
public static Form1 f = new Form1();
public static void GridStyle_01()
{ f.flex.Cols.Count = 5;
f.flex.Rows.Count = 5;
f.flex.Cols.DefaultSize = 30;
f.flex.Rows.DefaultSize = 30;
CellRange rng = f.flex.GetCellRange(0, 0, 0, 4);
rng.StyleNew.BackColor = Color.Red; }
public static void GridStyle_02()
{
f.flex.Cols.Count = 7;
f.flex.Rows.Count = 7;
f.flex.Cols.DefaultSize = 30;
f.flex.Rows.DefaultSize = 30;
CellRange rng = f.flex.GetCellRange(1, 0, 1, 6);
rng.StyleNew.BackColor = Color.Blue;
}
public static void GridStyle_03()
{
f.flex.Cols.Count = 9;
f.flex.Rows.Count = 9;
f.flex.Cols.DefaultSize = 30;
f.flex.Rows.DefaultSize = 30;
CellRange rng = f.flex.GetCellRange(2, 0, 2, 8);
rng.StyleNew.BackColor = Color.Green;
}
}
}
哪里错了呢?
GridStyle里定义一个Form1 f
然后又在外面CheckedChanged里调用class_demo.Style.GridStyle.GridStyle_01();
这里面涉及到两个Form1对象了,一个是f,一个CheckedChanged所在的对象晕,说得我也搞不清了
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
} private void Form1_Load(object sender, EventArgs e)
{ } private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
if (radioButton1.Checked)
{
style.GridStyle_01();
}
else
{
flex.Clear();
}
} private void radioButton2_CheckedChanged(object sender, EventArgs e)
{
if (radioButton2.Checked)
{
style.GridStyle_02();
}
else
{
flex.Clear();
}
} private void radioButton3_CheckedChanged(object sender, EventArgs e)
{
if (radioButton3.Checked)
{
style.GridStyle_03();
}
else
{
flex.Clear();
}
}
}
}【添加了一个style.cs】
namespace grid_class
{
class style
{
public static Form1 f = new Form1(); public static void GridStyle_01()
{ f.flex.Cols.Count = 5;
f.flex.Rows.Count = 5;
f.flex.Cols.DefaultSize = 30;
f.flex.Rows.DefaultSize = 30;
CellRange rng = f.flex.GetCellRange(0, 0, 0, 4);
rng.StyleNew.BackColor = Color.Red; }
public static void GridStyle_02()
{
f.flex.Cols.Count = 7;
f.flex.Rows.Count = 7;
f.flex.Cols.DefaultSize = 30;
f.flex.Rows.DefaultSize = 30;
CellRange rng = f.flex.GetCellRange(1, 0, 1, 6);
rng.StyleNew.BackColor = Color.Blue;
}
public static void GridStyle_03()
{
f.flex.Cols.Count = 9;
f.flex.Rows.Count = 9;
f.flex.Cols.DefaultSize = 30;
f.flex.Rows.DefaultSize = 30;
CellRange rng = f.flex.GetCellRange(2, 0, 2, 8);
rng.StyleNew.BackColor = Color.Green;
}
}
}
但是么有效果,错在哪里呢?
