在DataGridView中查找按钮控件

Question

How do I find button control inside DataGridView, I would do something like this in asp.net for GridView

    foreach (GridViewRow row in gridviewname.Rows)
    {
         Button btnColor= (Button)row.FindControl("btnColor");
    }

But I'm unable to-do the same in Windows forms application.Basically I'm trying to set property of button such as color,text etc.

1. If you do not need to change individual buttons you can customize the entire button column through its properties :

   You could get it during runtime like:

    buttonColumn = (DataGridViewButtonColumn)dataGridView.Columns .Where(column => column is DataGridViewButtonColumn) .First(); 

2. For individual cells you could try to change cell's Style property

    Boolean colorFlag = false; foreach (GridViewRow row in gridviewname.Rows) { row[buttonColumn].Style.BackColor = (colorFlag) : Colors.Green? Colors.Red; colorFlag = !colorFlag; } 

   But I'm not sure however that it will work - Change Color of Button in DataGridView Cell .

Answer 2

In datagridview you can get button through column.

this.mydatagridview.Columns("MybuttonColumn").DefaultCellStyle

Or if you have predefined columns then:

this.MyButtonColumn.DefaultCellStyle

Or if you use Visual Studio designer, then you can set column style values through designer.
