Datagridview full row selection but get single cell value

I have a datagridview that is a full row select. How would I grab th开发者_开发百科e data from only a certain cell no matter what cell in the row was clicked on since it highlights the entire row.

You can do like this:

private void datagridview1_SelectionChanged(object sender, EventArgs e)
{
  if (datagridview1.SelectedCells.Count > 0)
  {
    int selectedrowindex = datagridview1.SelectedCells[0].RowIndex;
    DataGridViewRow selectedRow = datagridview1.Rows[selectedrowindex];  
    string cellValue = Convert.ToString(selectedRow.Cells["enter column name"].Value);           
  }
}

---

If you want to get the contents of selected cell; you need the index of row and cell.

int rowindex = dataGridView1.CurrentCell.RowIndex;
int columnindex = dataGridView1.CurrentCell.ColumnIndex; 

dataGridView1.Rows[rowindex].Cells[columnindex].Value.ToString();

---

I know, I'm a little late for the answer. But I would like to contribute.

DataGridView.SelectedRows[0].Cells[0].Value

This code is simple as piece of cake

---

In the CellClick event you can write following code

string value =
      datagridviewID.Rows[e.RowIndex].Cells[e.ColumnIndex].FormattedValue.ToString();

Using the bove code you will get value of the cell you cliked. If you want to get value of paricular column in the clicked row, just replace e.ColumnIndex with the column index you want

---

you can get the values of the cell also as the current selection is referenced under CurrentRow

dataGridView1.CurrentRow.Cell[indexorname].FormattedValue

Here you can use index or column name and get the value.

DataGridView.CurrentRow.Cells[n]

See: http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.currentrow.aspx

---

I just want to point out, you can use .selectedindex to make it a little cleaner

string value = gridview.Rows[gridview.SelectedIndex].Cells[1].Text.ToString();

---

string value = dataGridVeiw1.CurrentRow.Cells[1].Value.ToString();

---

Just Use: dataGridView1.CurrentCell.Value.ToString()

        private void dataGridView1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            MessageBox.Show(dataGridView1.CurrentCell.Value.ToString());
        }

or

 // dataGrid1.Rows[yourRowIndex ].Cells[yourColumnIndex].Value.ToString()

 //Example1:yourRowIndex=dataGridView1.CurrentRow.Index (from selectedRow );
 dataGrid1.Rows[dataGridView1.CurrentRow.Index].Cells[2].Value.ToString()

 //Example2:yourRowIndex=3,yourColumnIndex=2 (select by programmatically )
  dataGrid1.Rows[3].Cells[2].Value.ToString()

---

this get me the text value of exact cell in data grid view

private void dataGridView_SelectionChanged(object sender, EventArgs e)
    {
        label1.Text = dataGridView.CurrentRow.Cells[#].Value.ToString();
    }

you can see it in label and change # wih the index of the exact cell you want

---

Use Cell Click as other methods mentioned will fire upon data binding, not useful if you want the selected value, then the form to close.

private void dgvProducts_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (dgvProducts.SelectedCells.Count > 0) // Checking to see if any cell is selected
    {
        int mSelectedRowIndex = dgvProducts.SelectedCells[0].RowIndex;

        DataGridViewRow mSelectedRow = dgvProducts.Rows[mSelectedRowIndex];

        string mCatagoryName = Convert.ToString(mSelectedRow.Cells[1].Value);

        SomeOtherMethod(mProductName); // Passing the name to where ever you need it

        this.close();
    }
}

---

For those who could not fire the click event, they may use following code

public Form1()
            {
                InitializeComponent();
                this.dataGridView1.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellClick);
            }

---

To get one cell value based on entire row selection:

if (dataGridView1.SelectedRows.Count > 0)
      {
         foreach (DataGridViewRow row in dataGridView1.Rows)
           {
               TextBox1.Text = row.Cells["ColumnName"].Value.ToString();
           }
      }
else
      {
        MessageBox.Show("Please select item!");
      }
     }

---

Simplest code is DataGridView1.SelectedCells(column_index).Value

As an example, for the first selected cell:

DataGridView1.SelectedCells(0).Value

---

dataGridView1.SelectedRows[0].Cells[0].Value;

---

for vb.net 2013 i use

DataGridView1.SelectedRows.Item(0).Cells(i).Value

where i is the cell number

---

Assigns cell 1 of dgwProduct lines to ProductId.

private void btnUpdate_Click(object sender, EventArgs e)
    {
            ProductId = Convert.ToInt32(dgwProduct.CurrentRow.Cells[0].Value);
    }

Here it puts all the cells in the row into the textbox.

private void dgwProduct_CellClick(object sender, DataGridViewCellEventArgs e)
    {
        var row=dgwProduct.CurrentRow;
        tbxProductName.Text =row.Cells[1].Value.ToString();
        tbxUnitPrice.Text = row.Cells[2].Value.ToString();
        tbxQuantityPerUnit.Text = row.Cells[3].Value.ToString();
        tbxStockUpdate.Text = row.Cells[4].Value.ToString();
    }

In this way, we assign all the cells in the dataGridView to the textboxes.

 private void DataGridView_SelectionChanged(object sender, EventArgs e)
    {
        if (dataGridViewX3.SelectedCells.Count > 0)
        {
            int selectedrowindex = dataGridViewX3.SelectedCells[0].RowIndex;
            DataGridViewRow selectedRow = dataGridViewX3.Rows[selectedrowindex];
            string cellValue = Convert.ToString(selectedRow.Cells[0].Value);
            Console.WriteLine(cellValue);
        }
    }
