推荐答案

foreach (DataGridViewRow dr in Result.Rows)
//Result is the datagrid name
            {
                if (dr.Cells[0].Selected == true)
                {
//program to execute on datagrid click 
}

hope this will be helpfull for you

试试这个



int Id =（int ）dataGridView1.SelectedRows [0] .Cells [0] .Value;

try this

int Id = (int)dataGridView1.SelectedRows[0].Cells[0].Value;

Grid1_SelectedIndexChanging（object sender，GridViewSelectEventArgs e）

{

value = Grid1.Rows [e.NewSelectedIndex] .Cells [1] .Text;
单元格中的
}

[输入列索引]然后你得到值。

Grid1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
value=Grid1.Rows[e.NewSelectedIndex].Cells[1].Text;
}
in Cells[enter your column index ] then u get the value.
