Now, at runtime I want to get the column index from Column Name.

and so on.

Is for/foreach loop is the only solution??

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
}
}

Happy coding :)

Solution 1

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

C#

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

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

C#

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;
    }

Thanks VJ,

My vote is +5. but, this answer is looking perfect when ColumnName and headerText are same.

But my requirement is I am getting headertext, through which I hv to get Index. (Note: My hederText and ColumnName are different)

VJ Reddy 10-Apr-12 5:43am

I understood your requirement. Now I modified the solution. Please see.

Vipin_Arora 10-Apr-12 5:53am

can't understand the line:
FirstOrDefault (n => n.HeaderText.Equals(headerText, StringComparison.InvariantCultureIgnoreCase));

can you plz clarify?

VJ Reddy 10-Apr-12 6:06am

FirstOrDefault is an extension method of IEnumerable interface. I thought that DataGridViewColumnCollection implements IEnumerable interface. Sorry. I have observed that DataGridViewColumnCollection does not implement IEnumerable. So the foreach loop can be used. I have modified my solution accordingly. Please see.

Did you get the index with the updated code?

Vipin_Arora 11-Apr-12 3:39am

Yeah Thanks a lot VJ, but I hv already got the answer same way (through Foreach Loop).. thx 4 your valuable suggestions..

You're welcome and thanks for your response.
