DataGridView .Net 3.5中的只读单元格 [英] Read-Only cell in DataGridView .Net 3.5

问题描述

我在将DataGridView的特定单元格的属性设置为只读时遇到问题。我将DataGridView dgv 绑定到DataSet（从存储过程检索的DataSet ），然后设置dgv列的属性，例如：颜色，字体，allignment等，它工作正常。现在我想要一些特定的dgv单元格是只读的，但它不起作用。我已经尝试了很多东西，例如



dgv.Item（0,1）.ReadOnly = True







dgv.Rows（0）.Cells（ 1）.ReadOnly = True





我们将非常感谢任何帮助。

解决方案

简单，



使用gridview的rowdatabound事件

并写上



if（e.Row.RowType == DataControlRowType.DataRow）

{

e.row.cells [6]。 enabled = false;

}： - O

我在这里有一个类似的问题，但我必须尝试一个想法。



在单元格中进行条件检查开始编辑，如果为true，则将您的单元格设置为只读，然后离开CellBeginEdit事件。

< pre lang =cs> if（Set_some_cells_readonly&&（e.ColumnIndex == 0 
 || e.ColumnIndex == 1 
 || e.ColumnIndex == 2））
 {
 //必须设置只读单元格，否则编辑继续正常
 //即使使用e.cancel  - 所有这一切都会终止开始进程
 dgv.Rows [e .RowIndex] .Cells [0] .ReadOnly = true; 
 dgv.Rows [e.RowIndex] .Cells [1] .ReadOnly = true; 
 dgv.Rows [e.RowIndex] .Cells [2] .ReadOnly = true; 
 dgv.CurrentCell.Selected = false; 
 //结束编辑是不够的，我们必须离开单元格否则
 //它在本回合中保持写入模式，并且在此编辑事件结束后仅变为只读
 // 。 
 dgv.CurrentCell = nullptr; 
返回; //以防其他任何代码'以后'滑入'
} 
其他
 {
 dgv.Rows [e.RowIndex] .Cells [0] .ReadOnly = false; 
 dgv.Rows [e.RowIndex] .Cells [1] .ReadOnly = false; 
 dgv.Rows [e.RowIndex] .Cells [2] .ReadOnly = false; 
} 

抱歉，我无法找到DataGridView的任何RowDataBound事件或类似的东西这一点。

Hi, I am having a problem with setting the property of a particular cell of DataGridView to read-only. I am binding a DataGridView "dgv" to a DataSet (DataSet retrieved from a stored procedure) and then setting the properties of dgv columns for e.g. color, font, allignment etc and it is working fine. Now I want some particular cells of dgv to be read-only, but it is not working. I've tried a lot of things for e.g.

dgv.Item(0, 1).ReadOnly = True

OR

dgv.Rows(0).Cells(1).ReadOnly = True


Any help will be greatly appreciated.

解决方案

Simply,

use rowdatabound event of gridview
and write

if (e.Row.RowType == DataControlRowType.DataRow)
{
e.row.cells[6].enabled=false;
} :-O

I have a similar question up here, but a thought has struck me which I must try.

Putting a conditional check in the cell begin edit, and if true, set your cells readonly then leave the CellBeginEdit event.

<pre lang="cs">if(Set_some_cells_readonly && (e.ColumnIndex == 0
    || e.ColumnIndex == 1
    || e.ColumnIndex == 2))
{
    // The cells must be set readonly otherwise edit proceeds as normal
    // even with an e.cancel - all that does is kill the begin process
    dgv.Rows[e.RowIndex].Cells[0].ReadOnly = true;
    dgv.Rows[e.RowIndex].Cells[1].ReadOnly = true;
    dgv.Rows[e.RowIndex].Cells[2].ReadOnly = true;
    dgv.CurrentCell.Selected = false;
    // It is not enough to end the edit, we must leave the cell otherwise
    // it remains in write mode for this turn and only becomes readonly
    // after this edit event ends.
    dgv.CurrentCell = nullptr;
    return; // just in case any other code 'slips in' at a later date
}
else
    {
        dgv.Rows[e.RowIndex].Cells[0].ReadOnly = false;
        dgv.Rows[e.RowIndex].Cells[1].ReadOnly = false;
        dgv.Rows[e.RowIndex].Cells[2].ReadOnly = false;
    }

Sorry, I am unable to find any RowDataBound Event of DataGridView or something like that.
