如何在Datagridview中将焦点设置到特定单元格 [英] How to set focus to a particular cell in Datagridview

问题描述

下面是在gridview中将焦点设置到特定单元格的代码，但它不起作用。



dtEmployeeDocumentDetails = objEmployeeMasterBusiness.GetAllEmployeeDocumentDetails（）;

DataGridViewCheckBoxColumn CHK =新DataGridViewCheckBoxColumn（）;

gvEmpDocDetails.Columns.Add（CHK）;

chk.HeaderText =选择;

chk.Name =chkselect;

gvEmpDocDetails.AllowUserToAddRows = false;

gvEmpDocDetails.DataSource = dtEmployeeDocumentDetails;

DataGridViewButtonColumn BTN =新DataGridViewButtonColumn（）;

btn.Name = btnDeleteEmpDocument;

btn.HeaderText =删除;

gvEmpDocDetails.Columns.Add（btn）;

gvEmpDocDetails.Columns [1]。可见= FALSE;

gvEmpDocDetails.Columns [4]。可见= FALSE;

gvEmpDocDetails.Columns [ 5]。可见= FALSE;

gvEmpDocDetails.Columns [6]。可见= FALSE;

gvEmpDocDetails.Columns [8]。可见= FALSE;

gvEmpDocDetails.Columns [12] .Visible = false;

gvEmpDocDetails.Rows [2] .Cells [0] .Selected = true;



你能告诉我如何将焦点设置到单元格，以便在单元格单击事件中编写的代码在表单加载时工作正常。



谢谢。

解决方案

首先，没有关注细胞。专注始终是键盘焦点;这是控件的属性，而不是它的任何部分。你需要的是选择，与焦点无关。



另外，选择的结果取决于 DataGridView的选择风格。请参阅 DataGridViewSelectionMode ：

http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.selectionmode.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/3c89df86.aspx [ ^ ]。



你需要 System.Windows.Forms.DataGridViewSelectionMode.CellSelect 。

-SA

还有另一种选择单元格的简单方法。通过设置dataGridView.CurrentCell。

eg;

  this  .dataGridView1 .CurrentCell =  this  .dataGridView1.Rows [ 1 ]。单元格[ 2 ]; 
 

 Grid1.Focus（）
 Grid1.CurrentCell = Grid1.Rows（1）.Cells（ 3）

Hi,

Below is the code to set focus to a particular cell in gridview, but its not working.

dtEmployeeDocumentDetails = objEmployeeMasterBusiness.GetAllEmployeeDocumentDetails();
DataGridViewCheckBoxColumn chk = new DataGridViewCheckBoxColumn();
gvEmpDocDetails.Columns.Add(chk);
chk.HeaderText = "Select";
chk.Name = "chkselect";
gvEmpDocDetails.AllowUserToAddRows = false;
gvEmpDocDetails.DataSource = dtEmployeeDocumentDetails;
DataGridViewButtonColumn btn = new DataGridViewButtonColumn();
btn.Name = "btnDeleteEmpDocument";
btn.HeaderText = "Delete";
gvEmpDocDetails.Columns.Add(btn);
gvEmpDocDetails.Columns[1].Visible = false;
gvEmpDocDetails.Columns[4].Visible = false;
gvEmpDocDetails.Columns[5].Visible = false;
gvEmpDocDetails.Columns[6].Visible = false;
gvEmpDocDetails.Columns[8].Visible = false;
gvEmpDocDetails.Columns[12].Visible = false;
gvEmpDocDetails.Rows[2].Cells[0].Selected = true;

Can you please let me know how to set focus to a cell so that the code written in my cell click event works fine when formloads.

Thanks.

解决方案

First of all, there is no a focus on a cell. Focus is always a keyboard focus; this is the attribute of a control, not any of its parts. What you need is selection, which is not related to focus.

Also, the result of selection depends on selection style of your DataGridView. Please see DataGridViewSelectionMode:
http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.selectionmode.aspx[^],
http://msdn.microsoft.com/en-us/library/3c89df86.aspx[^].

You will need System.Windows.Forms.DataGridViewSelectionMode.CellSelect.

There is another simple method to select the cell. by setting the dataGridView.CurrentCell.
eg;

this.dataGridView1.CurrentCell = this.dataGridView1.Rows[1].Cells[2];

Grid1.Focus()
 Grid1.CurrentCell = Grid1.Rows(1).Cells(3)
