How to set column widths to a specified width in the grid

Question

I can see the various modes to calculate column widths in the grid but I want to programmatically set  the widths of each column to my own fixed values. How do I do that?

Hi David
Adler,

You can achieve your requirement to set the width for the columns through the
below ways,Case 1: Manually defining columnsWhen you are defining columns manually, you can
set the column width using the Width property shown below,

sfDataGrid1.AutoGenerateColumns = false;
  sfDataGrid1.DataSource =
  viewModel.OrdersListDetails;
  this.sfDataGrid1.Columns.Add(new GridTextColumn()
  { MappingName = "OrderID", HeaderText = "Order
  ID",
  Width=150 });
  this.sfDataGrid1.Columns.Add(new GridTextColumn()
  { MappingName = "CustomerID", HeaderText = "Customer
  ID" ,
  Width=200 });

Case 2: Auto-generating columnsWhen you are using auto-generating columns you
can set the column width using SfDataGrid.AutoGeneratingColumn event like shown
below,

sfDataGrid1.AutoGenerateColumns = true;
  sfDataGrid1.AutoGeneratingColumn +=
  SfDataGrid1_AutoGeneratingColumn;
  
  private void SfDataGrid1_AutoGeneratingColumn(object sender,
  Syncfusion.WinForms.DataGrid.Events.AutoGeneratingColumnArgs e)
   {
       if (e.Column.MappingName
  == "OrderID")
           e.Column.Width
  = 150;
       if (e.Column.MappingName
  == "CustomerID")
           e.Column.Width
  = 200;
   }
