GridView中所有列的列宽 [英] Column Width for all Columns in GridView

问题描述

各位大家好，

我很长一段时间没有写过一行，而且我正在学习c＃，我是编程新手。



我正在处理表格和列，我无法为网格视图中的所有列设置固定宽度。



任何人都可以帮帮我？



提前谢谢。

解决方案

Datagridview有一个属性AutoSizeColumnsMode，带有以下选项

 //摘要：
 //定义值 for 指定如何调整列的宽度。 
  public   enum  DataGridViewAutoSizeColumnsMode 
 {
 //汇总：列width 执行 不自动调整。 
无=  1 ，
 // 
 //摘要：列宽调整 适合列标题单元格的 。 
 ColumnHeader =  2 ，
 //摘要：
 //列宽调整                    
 AllCellsExceptHeader =  4 ，
 // 
 //摘要：
 //列宽调整> 符合列 列列列列的内容标题单元格。 
 AllCells =  6 ，
 // 
 //摘要：列宽调整   所有单元格 列
 //中的内容当前显示在屏幕上的行中的，不包括标题单元格。 
 DisplayedCellsExceptHeader =  8 ，
 // 
 //摘要：
 //列宽调整> 符合所有单元格的内容 列
 //当前显示在屏幕上的 行，包括标题单元格。 
 DisplayedCells =  10 ，
 // 
 //汇总：
 //调整列宽以便宽度所有列的 所有列都完全填充控件的
 //显示区域，仅需要水平滚动 保持
 //列宽在System.Windows.Forms.DataGridViewColumn.MinimumWidth 
 //属性值之上。相对列宽由相对System.Windows.Forms.DataGridViewColumn.FillWeight 
 //属性值确定。 
 Fill =  16 ，
} 

设置属性：AutoSizeColumnsMode = ColumnHeader它将根据列标题字符串宽度自动调整列的大小。

 GridView1.Columns [i] .ItemStyle.Width = colWidth ; 

第二解决方案:::::::

step1：创建一个函数，如下所示

 public DataGridViewTextBoxColumn GetDataGridViewColumn（ref DataGridView DGV，string colName，string colHeader，int colWidth，bool colVisibility = true，string DataPropertyName =） 
 {
 DataGridViewTextBoxColumn DGVTbCol = new DataGridViewTextBoxColumn（）; 
 DGVTbCol.Name = colName; 
 if（string.IsNullOrEmpty（DataPropertyName））{
 DGVTbCol.DataPropertyName = colName; 
} else {
 DGVTbCol.DataPropertyName = DataPropertyName; 
} 
 
 DGVTbCol.HeaderText = colHeader; 
 DGVTbCol.DefaultCellStyle.Alignment = DataGridViewContentAlignment.TopLeft; 
 DGVTbCol.HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter; 
 DGVTbCol.Width = colWidth; 
 DGVTbCol.Visible = colVisibility; 
 if（colVisibility）{
 DGV.Tag + = colWidth; 
} 
返回DGVTbCol; 
} 

第二步： -

 String C_Id =1stColumnName
 String C_Id2 =2ndColumnName

  private   void  SetColumns（ ref  DataGridView DGV）
 {
  int  AlignLeft =  0 ; 
  int  AlignRight =  1 ; 
  int  AlignCenter =  2 ; 
  int  ControlStart =  0 ; 
  int  CtrlTop =  0 ; 
  int  ColWidth =  0 ; 
 
 DGV.AutoGenerateColumns =  false ; 
 DGV.MultiSelect =  true ; 
 DGV.ReadOnly =  false ; 
 DGV.Tag =  0 ; 
 DGV.Columns.Clear（）; 
 ColWidth =  70 ;  //  指定您想要的宽度 
 DGV.Columns.Add（GetDataGridViewColumn（DGV，C_Id） ，  ColumnName，ColWidth，False））
 DGV.Columns.Add（GetDataGridViewColumn（ DGV，C_Id2，  2ndColumnName，ColWidth，True））
 
} 

Hello everybody,
I am new in programming after a long period of 10 years without writing a line and I am learning c# by myself.

I am dealing with Forms and Columns and I can not get the way of setting a fixed width for all the columns in a Grid View.

Can anyone help me?

Thank you in advance.
David

解决方案

Datagridview has a property AutoSizeColumnsMode with following options

// Summary:
//     Defines values for specifying how the widths of columns are adjusted.
public enum DataGridViewAutoSizeColumnsMode
{
   //Summary:The column widths do not automatically adjust.
   None = 1,
   //
   //Summary:The column widths adjust to fit the contents of the column header cells.
   ColumnHeader = 2,
   // Summary:
   //The column widths adjust to fit the contents of all cells in the columns,excluding header cells.
   AllCellsExceptHeader = 4,
   //
   // Summary:
   //The column widths adjust to fit the contents of all cells in the columns,including header cells.
   AllCells = 6,
   //
   //Summary:The column widths adjust to fit the contents of all cells in the columns
   //that are in rows currently displayed onscreen, excluding header cells.
   DisplayedCellsExceptHeader = 8,
   //
   // Summary:
   //The column widths adjust to fit the contents of all cells in the columns
   //that are in rows currently displayed onscreen, including header cells.
   DisplayedCells = 10,
   //
   // Summary:
   //The column widths adjust so that the widths of all columns exactly fill the
   //display area of the control, requiring horizontal scrolling only to keep
   //column widths above the System.Windows.Forms.DataGridViewColumn.MinimumWidth
   //property values. Relative column widths are determined by the relative System.Windows.Forms.DataGridViewColumn.FillWeight
   //property values.
   Fill = 16,
  }

set the property :AutoSizeColumnsMode=ColumnHeader it will auto resize your column based on the Column Header string width.

GridView1.Columns[i].ItemStyle.Width = colWidth;

2nd Solution:::::::
step1:-Create a function,given below

public DataGridViewTextBoxColumn GetDataGridViewColumn(ref DataGridView DGV, string colName, string colHeader, int colWidth, bool colVisibility = true, string DataPropertyName = "")
{
	DataGridViewTextBoxColumn DGVTbCol = new DataGridViewTextBoxColumn();
	DGVTbCol.Name = colName;
	if (string.IsNullOrEmpty(DataPropertyName)) {
		DGVTbCol.DataPropertyName = colName;
	} else {
		DGVTbCol.DataPropertyName = DataPropertyName;
	}

	DGVTbCol.HeaderText = colHeader;
	DGVTbCol.DefaultCellStyle.Alignment = DataGridViewContentAlignment.TopLeft;
	DGVTbCol.HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter;
	DGVTbCol.Width = colWidth;
	DGVTbCol.Visible = colVisibility;
	if (colVisibility) {
		DGV.Tag += colWidth;
	}
	return DGVTbCol;
}

2nd Step:-

String C_Id = "1stColumnName"
String C_Id2="2ndColumnName"

private void SetColumns(ref DataGridView DGV)
{
    int AlignLeft = 0;
    int AlignRight = 1;
    int AlignCenter = 2;
    int ControlStart = 0;
    int CtrlTop = 0;
    int ColWidth = 0;

    DGV.AutoGenerateColumns = false;
    DGV.MultiSelect = true;
    DGV.ReadOnly = false;
    DGV.Tag = 0;
    DGV.Columns.Clear();
ColWidth=70; //Specify width as u want
  DGV.Columns.Add(GetDataGridViewColumn(DGV, C_Id, "ColumnName", ColWidth, False))
DGV.Columns.Add(GetDataGridViewColumn(DGV, C_Id2, "2ndColumnName",ColWidth, True))

}
