Datagridview How to set a cell in editing mode

Question

I need to programmatically set a cell in editing mode  I know that setting that cell as CurrentCell and then call the method BeginEdit bool   it should happen  but in my case  it doesn t   I really want that  with my DGV with several columns  the user can ONLY select and also edit the first two  The other columns are already read-only  but the user can select them  and that is what I don t want   So I was thinking  tell the user to TAB everytime it has finished writing on the cell  then select the second cell  then tab again and it select and begin edit the next row s first cell     How can I do this

I know this is an old question  but none of the answers worked for me  because I wanted to reliably  always be able to  set the cell into edit mode when possibly executing other events like Toolbar Button clicks  menu selections  etc  that may affect the default focus after those events return   I ended up needing a timer and invoke   The following code is in a new component derived from DataGridView   This code allows me to simply make a call to myXDataGridView CurrentRow SelectCellFocus myDataPropertyName   anytime I want to arbitrarily set a databound cell to edit mode  assuming the cell is Not in ReadOnly mode       If the DGV does not have Focus prior to a toolbar button Click      then the toolbar button will have focus after its Click event handler returns     To reliably set focus to the DGV  we need to time it to happen After event handler procedure returns   private string m SelectCellFocus DataPropertyName       private System Timers Timer timer CellFocus   null   public void CurrentRow SelectCellFocus string sDataPropertyName         This procedure is called by a Toolbar Button s Click Event to select and set focus to a Cell in the DGV s Current Row    m SelectCellFocus DataPropertyName   sDataPropertyName    timer CellFocus   new System Timers Timer 10     timer CellFocus Elapsed    TimerElapsed CurrentRowSelectCellFocus    timer CellFocus Start        void TimerElapsed CurrentRowSelectCellFocus object sender  System Timers ElapsedEventArgs e      timer CellFocus Stop      timer CellFocus Elapsed -  TimerElapsed CurrentRowSelectCellFocus    timer CellFocus Dispose         We have to Invoke the method to avoid raising a threading error   this Invoke  MethodInvoker delegate         Select Cell m SelectCellFocus DataPropertyName             private void Select Cell string sDataPropertyName          When the Edit Mode is Enabled  set the initial cell to the Description   foreach  DataGridViewCell dgvc in this SelectedCells              Clear previously selected cells     dgvc Selected   false         foreach  DataGridViewCell dgvc in this CurrentRow Cells             Select the Cell by its DataPropertyName     if  dgvc OwningColumn DataPropertyName    sDataPropertyName              this CurrentCell   dgvc        dgvc Selected   true        this Focus          return

Well  I would check if any of your columns are set as ReadOnly  I have never had to use BeginEdit  but maybe there is some legitimate use  Once you have done dataGridView1 Columns       ReadOnly   False   the fields that are not ReadOnly should be editable  You can use the DataGridView CellEnter event to determine what cell was entered and then turn on editing on those cells after you have passed editing from the first two columns to the next set of columns and turn off editing on the last two columns

Setting the CurrentCell and then calling BeginEdit true  works well for me   The following code shows an eventHandler for the KeyDown event that sets a cell to be editable    My example only implements one of the required key press overrides but in theory the others should work the same   and I m always setting the  0  0  cell to be editable but any other cell should work       private void dataGridView1 KeyDown object sender  KeyEventArgs e                if  e KeyCode    Keys Tab  amp  amp  dataGridView1 CurrentCell ColumnIndex    1                        e Handled   true              DataGridViewCell cell   dataGridView1 Rows 0  Cells 0               dataGridView1 CurrentCell   cell              dataGridView1 BeginEdit true                                    If you haven t found it previously  the DataGridView FAQ is a great resource  written by the program manager for the DataGridView control  which covers most of what you could want to do with the control
