Winforms – Devexpress GridControl Format Conditions

devexpressgridviewwinforms

Is there anyone who has experience with the Devexpress GridControl.

I have a class which has a List of Objects in it. (This class is binded to the Grid).
This grid has a few columns to display the class.

I want a row to have another color when the list of objects.count is > 1

I've tried to like make an In-Place Editor Repository LookUpEdit item so I have the List of objects to set into a column.

There are few methods that suit your needs. you can use the Appearance specific events that are more flexible.

Check the Customizing Appearances of Individual Rows and Cells on devExpress documentation.

Check this how can you change the appearance conditionally on the basis of some column value:

using DevExpress.XtraGrid.Views.Grid;

private void gridView1_RowStyle(object sender, 
DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e) {
   GridView View = sender as GridView;
   if(e.RowHandle >= 0) {
      string category = View.GetRowCellDisplayText(e.RowHandle, View.Columns["Category"]);
      if(category == "Beverages") {
         e.Appearance.BackColor = Color.Salmon;
         e.Appearance.BackColor2 = Color.SeaShell;
      }            
   }
}

namespace Samples
{
    public partial class Form1 : Form
    {
        private GridControl grid;
        private GridView view;

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {            
            view.ShowFilterPopup(view.Columns[0]);                      
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            grid = new GridControl();
            view = new GridView();

            grid.Dock = DockStyle.Fill;
            grid.ViewCollection.Add(view);
            grid.MainView = view;

            view.GridControl = grid;
            view.OptionsView.ShowAutoFilterRow = true;
            GridColumn column = view.Columns.Add();
            column.Caption = "Name";
            column.FieldName = "Name";
            column.Visible = true;

            // The grid control requires at least one row 
            // otherwise the FilterPopup dialog will not show
            DataTable table = new DataTable();
            table.Columns.Add("Name");
            table.Rows.Add("Hello");
            table.Rows.Add("World");
            grid.DataSource = table;

            this.Controls.Add(grid);
            grid.BringToFront();
        }
    }
}

C# – How to display a RepositoryItemHyperLinkEdit control inside a DevExpress GridControl

You can use the following code to display hyperlink in grid column:

GridColumn hyperLinkColumn = gridView1.Columns["Hyperlink"];
//...
RepositoryItemHyperLinkEdit hyperLinkEdit = new RepositoryItemHyperLinkEdit();
hyperLinkColumn.ColumnEdit = hyperLinkEdit; // this line associated hyperlink with column
hyperLinkEdit.OpenLink += hyperLinkEdit_OpenLink;
//...
void hyperLinkEdit_OpenLink(object sender, OpenLinkEventArgs e) {
    MessageBox.Show("HyperLinkEdit clicked!");
}

If you want to display aditional button in the same column you can use the following approach:

hyperLinkEdit.Buttons[0].Kind = ButtonPredefines.Glyph;
hyperLinkEdit.Buttons[0].Caption = "Get SQL Query";
hyperLinkEdit.ButtonClick += hyperLinkEdit_ButtonClick;
hyperLinkColumn.ShowButtonMode = ShowButtonModeEnum.ShowAlways; // always display button in this column
//...
void hyperLinkEdit_ButtonClick(object sender, ButtonPressedEventArgs e) {
    MessageBox.Show("HyperLinkEdit's button clicked!");
}
