DataGridView Click event

Many Many Thanks My Friend

i will have more questions during the weekends.

Have a nice weekend

Also check for the DBNull Value

if(dataGridView[2, e.RowIndex].Value != null && dataGridView[2, e.RowIndex].Value !=  DBNull.Value)

{   textBox2.Text = ( string)dataGidView[2,e.RowIndex].Value; }

else {  MessageBox.Show(" Field is empty"); }

When I have this code:

private void dataGridView1_CellContntClick( object sender, DataGridViewCellEventArgs e)

if(dataGridView[2, e.RowIndex].Value !=null)

{   textBox2.Text = ( string)dataGidView[2,e.RowIndex].Value; }

else {  MessageBox.Show(" Field is empty"); }

it give me the error ( Unable to cast object of type System.DBNull' to type System.String'.)

It should work fine without error, can you send more code to analyze? What is the error you are getting?

You can also check the value returned before assigning to the TextBox.Text

If(dataGridView1[2, e.RowIndex].Value != null)

            {

                textBox1.Text = (string)dataGridView1[2, e.RowIndex].Value;

            }

I have done this in datagrid of windows application.
Get the logic from the code and apply it in your code.

private void dtgUsers_Click(object sender, System.EventArgs e)
 {

   DataGridCell currentCell;
   string currentCellData="";
   // Get the current cell.
   currentCell = dtgUsers.CurrentCell;
   // Get the current cell's data.
   currentCellData = (string)dtgUsers[currentCell.RowNumber,currentCell.ColumnNumber];
   // Set the TextBox's text to that of the current cell.
   textbox1.text = currentCellData;
}

Note: 'dtgUsers' id of datagrid

You can use any of these statements to get value in the selected cell

textBox1.Text = (string)dataGridView1[e.ColumnIndex, e.RowIndex].Value;

textBox1.Text = (string)dataGridView1.CurrentCell.Value;

textBox1.Text = (string)dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;

If you want only Id value when you selecet any column in a particular row, you can use, change the values in red font as per your requirement that is column(Id column) you are looking for

Thanks.

But the one you send me it will give me the index of the column. Let me give you an example

I have 3 Columns A, B & C  with the following information in A i have a name , in B a lastname and in C the ID for example

 When i click on one of the items in the  row it will give me the Column C item( ID) in the textbox1.text

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
