How would i go about checking if a row's cells have data in them, ie not empty/null.

I've been trying the following:

        if (dgvClient.SelectedRows.Count > 0)
        {
            DataGridViewRow currentRow = dgvClient.SelectedRows[0];
            if (currentRow.Cells.ToString() != String.Empty)
            {
                //The code that will be here will open a form
            }
            else
            {
                MessageBox.Show("Select a non null row");
            }
        }

However, it doesn't appear to be working, and I'm out of ideas :/

Thanks for any help, Ari

.Cells is a collection of DataGridViewCell objects.

You need to iterate through that collection & test each cell to see if it has a value...

if (currentRow.Cells.Count > 0) 
{      
   bool rowIsEmpty = true;    

   foreach(DataGridViewCell cell in currentRow.Cells)    
   {
      if(cell.Value != null) 
      { 
          rowIsEmpty = false;
          break;
      }    
   }

   if(rowIsEmpty)
   {
       MessageBox.Show("Select a non null row"); 
   }
   else
   {
       //DoStuff
   }
}

RowEnter event occurs when a row receives input focus but before it becomes the current row. For example, move from one cell to another cell in a different row. Check each cell value: void dataGridView1_RowEnter(object sender, DataGridViewCellEventArgs e) { dataGridView1.Rows[e.RowIndex].ReadOnly = checkrow(dataGridView1.Rows[e.RowIndex]); } bool checkrow(DataGridViewRow testrow) { for (int i = 0; i < testrow.Cells.Count; i++) { if (testrow.Cells[i].Value !=

Another method to check if a new empty row is selected perhaps

if(dataGridView.CurrentRow.Index == dataGridView.Rows.Count -1)
{
    //you selected a new row
}

How to check if selected row is empty in DataGridView, How to check if a selected row in a datagridview is empty(has no item). Nov 4 2011 4:21 AM. Hey! First time poster here, first of all I wasn't sure if this is the right​  In my WinForms I have DataGridView.I wanted to select full row at once so I set SelectionMode as FullRowSelect.And now I have problem, because at the beginning my form underlines first row (set of selected rows is empty, the first row is not selected but just underlined).

         for (int i = 0; i < dataGridView1.Rows.Count; i++)
            {
                for (int j = 0; j < dataGridView1.Columns.Count; j++)
                {
                    DataGridViewCell cell = dataGridView1[j, i];
                    object value = cell.Value;
                    if (value == string.Empty)
                    {
                             //do
                    }
                }

[Solved] C# check if datagridview column is empty, How should i check using C# programming. event as the following code, what I confuse is that why you don't want to remove the row if it's empty with nothing? And more usually there's no empty row in the DataGridView. You can get the selected cells, rows, or columns from a DataGridView control by using the corresponding properties: SelectedCells, SelectedRows, and SelectedColumns. In the following procedures, you will get the selected cells and display their row and column indexes in a MessageBox. To get the selected cells in a DataGridView control

I think this can be done by handling DataGridView.RowEnter event. RowEnter event occurs when a row receives input focus but before it becomes the current row. For example, move from one cell to another cell in a different row.

Check each cell value:

 void dataGridView1_RowEnter(object sender, DataGridViewCellEventArgs e)
 {
     dataGridView1.Rows[e.RowIndex].ReadOnly = checkrow(dataGridView1.Rows[e.RowIndex]);
 }

 bool checkrow(DataGridViewRow testrow)
 {
        for (int i = 0; i < testrow.Cells.Count; i++)
        {
            if (testrow.Cells[i].Value != null)
            {
                // if datagridview is databound, you'd better check whether the cell value is string.Empty
                if (testrow.Cells[i].Value.ToString() != string.Empty)
                {
                    // if value of any cell is not null, this row need to be readonly
                    return true;
                }

                // if there is an unbound checkbox column, you may need to check whether the cell value is null or false(uncheck).
            }
        }

        // else false
        return false;
 }

C# Windows Forms, Well, without debugging you can never be sure what data you are getting. As far as comparision with empty string is concerned, I would use  i have a datagridview control. i am displaying all the students information in datagrid view based on their class. in database i have a student table it contains no.of columns like their sno,sname,age,marks etc but iam showing only sno and sname in datagridview control. sno sname . 1 xyz. 2 abc

Surprised no linq answer so here it is:

if (dataGridView1.Rows.Cast<DataGridViewRow>()
      .Any(x => x.Cells.Cast<DataGridViewCell>()
      .Any(c => c.Value != null)))

DataGrid Rows are of DataCollection type which implements IEnumerable. You just need to cast the cells and rows.

  • Why don't you check for individual cells in a loop?
  • What kind of empty row? There is a mode which allows you to add rows but this does not mean an empty row!
  • may be this helps
