How to set the number of rows and columns in a WinForms GridControl?

2 mins read

Setting row and column count

You can change the Grid’s RowCount and ColCount properties by using the designer. Set these properties after calling InitializeComponent in the form’s constructor or anytime later in your code using the following code example.

Using direct properties

C#

// set RowCount for GridControl
gridControl1.RowCount = 20;
// set ColCount for GridControl
gridControl1.ColCount = 120;

VB

' set RowCount for GridControl
gridControl1.RowCount = 20
' set ColCount for GridControl
gridControl1.ColCount = 120

Using Events

The events QueryRowCount and QueryColCount are used to set the count for rows and columns.

C#

//Hook these events to set the RowCol count 
gridControl1.QueryColCount += gridControl1_QueryColCount;
gridControl1.QueryRowCount += gridControl1_QueryRowCount;
void gridControl1_QueryColCount(object sender, GridRowColCountEventArgs e)
{
    //Set ColCount for GridControl
    e.Count = int.Parse(colCountText.Text);
    e.Handled = true;
}
void gridControl1_QueryRowCount(object sender, GridRowColCountEventArgs e)
{
    //Set RowCount for GridControl
    e.Count = int.Parse(rowCountTxt.Text);
    e.Handled = true;
}

VB

//Hook these events to set the RowCol count 
gridControl1.QueryColCount += gridControl1_QueryColCount;
gridControl1.QueryRowCount += gridControl1_QueryRowCount;
Private Sub gridControl1_QueryColCount(ByVal sender As Object, ByVal e As GridRowColCountEventArgs)
     'Set ColCount for GridControl
     e.Count = Integer.Parse(colCountText.Text)
     e.Handled = True
End Sub
Private Sub gridControl1_QueryRowCount(ByVal sender As Object, ByVal e As GridRowColCountEventArgs)
     'Set RowCount for GridControl
     e.Count = Integer.Parse(rowCountTxt.Text)
     e.Handled = True
End Sub
