如何防止Datagridview在打开时选择第一个单元格 [英] How to prevent Datagridview from selecting the first cell on opening
问题描述
我正试图找到一种方法来防止我的datagridview选择第一个单元格作为默认单元格。现在我有代码,如果负数在导入的单元格中,我的datagridview中的单元格的背景颜色变为红色。但是,这在我的第一个单元格中无法正常工作,因为它在导入时默认已突出显示。如果有人能够找到如何关闭单元格的选择,我将非常感激! :)
我知道它一定很像 DataGridView1.CurrentCell.Selected = False
就是这么简单:)
datagridview1.ClearSelection()
< blockquote>我按照你的描述编写了一个测试,并且所有单元格都正确着色。

public partial class Form1:表格
{
private Random rnd;
private int nSize = 4 ;
public Form1()
{
InitializeComponent();
rnd = new Random();
for ( int c = 0 ; c < nSize; c ++)
{
this .dataGridView1 .Columns.Add( Col + c.ToString(), Col + c.ToString());
}
}
私有 void buttonImport_Click( object sender,EventArgs e)
{
this .dataGridView1.Rows.Clear ();
int n = this .dataGridView1.Columns.Count;
string [] nums;
for ( int r = 0 ; r < nSize; r ++)
{
nums = new string [n];
for ( int c = 0 ; c < n; c ++)
{
nums [c] =(rnd.Next(-10, 10 跨度>))的ToString();
}
此 .dataGridView1.Rows.Add(nums);
}
ColorCells();
}
私有 void ColorCells()
{
int n = 此 .dataGridView1.Columns.Count;
for ( int r = 0 ; r < nSize; r ++)
{
for (< span class =code-keyword> int c = 0 ; c < n ; c ++)
{
string val =( string )此跨度> .dataGridView1.Rows [R] .Cells并[c]。价值;
int v;
if ( Int32 .TryParse(val, out v)== false ) continue ;
if (v< 0)
this .dataGridView1。行[r]。细胞[c] .Style.BackColor = Color.Red;
else
this .dataGridView1.Rows [r] .Cells [E] .Style.BackColor = Color.White;
}
}
}
}
I'm trying to find a way to prevent my datagridview from selecting the first cell as default cell. Right now I have code that turns the backcolor of the cells in my datagridview to red if negative numbers are in the cells on import. However this won't work properly in my first cell since its already highlighted by default on import. If anyone can find out how to turn the selecting of the cell off I would greatly appreciate it! :)
I know it must be something simple like DataGridView1.CurrentCell.Selected = False
It is just that simple :)
datagridview1.ClearSelection()
I wrote a test following you're description and all cells colored correctly.

public partial class Form1 : Form { private Random rnd; private int nSize = 4; public Form1() { InitializeComponent(); rnd = new Random(); for (int c = 0; c < nSize; c++) { this.dataGridView1.Columns.Add("Col" + c.ToString(), "Col" + c.ToString()); } } private void buttonImport_Click(object sender, EventArgs e) { this.dataGridView1.Rows.Clear(); int n = this.dataGridView1.Columns.Count; string[] nums; for (int r = 0; r < nSize; r++) { nums = new string[n]; for (int c = 0; c < n; c++) { nums[c] = (rnd.Next(-10, 10)).ToString(); } this.dataGridView1.Rows.Add(nums); } ColorCells(); } private void ColorCells() { int n = this.dataGridView1.Columns.Count; for (int r = 0; r < nSize; r++) { for (int c = 0; c < n; c++) { string val = (string) this.dataGridView1.Rows[r].Cells[c].Value; int v; if(Int32.TryParse(val, out v) == false) continue; if(v<0) this.dataGridView1.Rows[r].Cells[c].Style.BackColor = Color.Red; else this.dataGridView1.Rows[r].Cells[c].Style.BackColor = Color.White; } } } }
