How to set the number of rows and columns in a WinForms GridControl?
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
// set RowCount for GridControl
gridControl1.RowCount = 20;
// set ColCount for GridControl
gridControl1.ColCount = 120;' set RowCount for GridControl
gridControl1.RowCount = 20
' set ColCount for GridControl
gridControl1.ColCount = 120Using
Events
The events QueryRowCount and QueryColCount are used to set the count for rows and columns.
//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;
}'Hook these events to set the RowCol count
AddHandler gridControl1.QueryColCount, AddressOf gridControl1_QueryColCount
AddHandler gridControl1.QueryRowCount, AddressOf 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 SubThe following
