Getting data from selected datagridview row and which event

Question

I have a DataGridView  Selectionmode  FullRowSelect  on a windows form along with some textboxes  so what i want to do is that whenever a user selects a row click or double click maybe   the contents of that row must be displayed in the text boxes   i tried out this codes   private void dataGridView1 CellDoubleClick object sender  DataGridViewCellEventArgs e        MessageBox Show  CEll Double Click event calls        int rowIndex   e RowIndex      DataGridViewRow row   dataGridView1 Rows rowIndex       textBox5 Text   row Cells 1  Value     private void dataGridView1 CellClick object sender  DataGridViewCellEventArgs e        int rowIndex   e RowIndex      DataGridViewRow row   dataGridView1 Rows rowIndex       textBox5 Text   dataGridView1 Rows 1  Cells 1  Value ToString      row Cells 1  Value      there are many other textboxes  but the main problem is that none of the event seems to be triggered  what event should i use to do so  or is there some property of datagrid that i might have set wrong  Any help would be appreciated

You can try this click event  private void dataGridView1 CellContentClick object sender  DataGridViewCellEventArgs e        if  e RowIndex  gt   0                DataGridViewRow row   this dataGridView1 Rows e RowIndex           Eid txt Text   row Cells  Employee ID   Value ToString            Name txt Text   row Cells  First Name   Value ToString            Surname txt Text   row Cells  Last Name   Value ToString

You can use SelectionChanged event since you are using FullRowSelect selection mode  Than inside the handler you can access SelectedRows property and get data from it  Example   private void dataGridView SelectionChanged object sender  EventArgs e         foreach  DataGridViewRow row in dataGridView SelectedRows                 string value1   row Cells 0  Value ToString            string value2   row Cells 1  Value ToString                            You can also walk through the column collection instead of typing indexes

You should check your designer file  Open Form1 Designer cs and find this line  windows Form Designer Generated Code  Expand this and you will see a lot of code  So check Whether this line is there inside datagridview1 controls if not place it   this dataGridView1 CellClick    new System Windows Forms DataGridViewCellEventHandler this dataGridView1 CellClick      I hope it helps

First take a label  set its visibility to false  then on the DataGridView CellClick event write this  private void dataGridView1 CellClick object sender  DataGridViewCellEventArgs e        label Text dataGridView1 Rows e RowIndex  Cells  Your Coloumn name   Value ToString           then perform your select statement according to that label      try it it might work for you

Simple solution would be as below  This is improvement of solution from vale    private void dgMapTable SelectionChanged object sender  EventArgs e         int active map 0      if dgMapTable SelectedRows Count gt 0          active map   dgMapTable SelectedRows 0  Index         User code if required Process ROW active map       Note for other reader  for above code to work FullRowSelect selection mode for datagridview should be used  You may extend this to give message if more than two rows selected
