Hi,

In windows Apllication, I have a datagridview (say:dgv), I have some columns (A,B,C).
Now, at runtime I want to get the column index from Column Name.
Suppose if I pass "A", then result should be "0". in case of "B": 1
and so on.

can somebody please help?
Is for/foreach loop is the only solution??

推荐答案

DataGridViewColumn类的Index属性可用于上述目的，例如

The Index property of DataGridViewColumn class can be used for the above purpose like

dgv.Columns["A"].Index.ToString();

从ColumnHeaderText获取列的索引 [/编辑]

To get index of the Column from ColumnHeaderText[/Edit]

string headerText = "A";
string index = string.Empty;
foreach (DataGridViewColumn column in dgv.Columns)
    if (column.HeaderText.Equals(headerText, StringComparison.InvariantCultureIgnoreCase)){
        index = column.Index.ToString();
        break;
    }

int intIndex = gridview.rows [e.rowindex] .value

int intIndex=gridview.rows[e.rowindex].value

我希望这是您正在寻找的

I hope this is what you are looking for

public Form1()
{
InitializeComponent();
}
private void detailsToolStripMenuItem_Click(object sender, EventArgs e)
{
int index = this.dataGridView.???????????????????
DataGridViewRow dgvrow = this.dataGridView1.Rows[index];
DataRowView drvrow = (DataRowView)dgvrow.DataBoundItem;
if (drvrow != null)
{
String contract = drvrow["ttttt"].ToString();
ShowContractDetail(contract);
}
}
private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
this.dataGridView1.Rows[e.RowIndex].Selected = true;  //the rows get selected. Goodie
}
}
