ColumnGroupsView height

[Dominik]

Sample code below. Just copy, paste and run. :)

var grid = new RadGridView
{
    Dock = DockStyle.Fill,
    AutoSizeRows = false,
    AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill

};

grid.Columns.Add(new GridViewTextBoxColumn() { Name = "column1", HeaderText = "Column 1" });
grid.Columns.Add(new GridViewTextBoxColumn() { Name = "column2", HeaderText = "Column 2" });
grid.Columns.Add(new GridViewTextBoxColumn() { Name = "column3", HeaderText = "Column 3" });
grid.Columns.Add(new GridViewTextBoxColumn() { Name = "column4", HeaderText = "Column 4" });

var columnGroupsView = new ColumnGroupsViewDefinition();
columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup("Group 1 Line 1" + Environment.NewLine + "Group 1 Line 2"));
columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows[0].ColumnNames.Add("column1");
columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows[0].ColumnNames.Add("column2");

columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup("Group 2 Line 1" + Environment.NewLine + "Group 2 Line 2"));
columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows[0].ColumnNames.Add("column3");
columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows[0].ColumnNames.Add("column4");

grid.ViewDefinition = columnGroupsView;

var form = new RadForm();
form.Controls.Add(grid);
form.ShowDialog();

 

How to change by code height of group row? Please see attached image.

Important: I want to stay with AutoSizeRows = false.

Also how to change second row height (columns).

Hi Dominik,

You need to set the RowSpan and MinHeight properties. Here is an example:

var group = new GridViewColumnGroup("Group 1 Line 1" + Environment.NewLine + "Group 1 Line 2");
group.RowSpan = 50;
columnGroupsView.ColumnGroups.Add(group);

var groupRow = new GridViewColumnGroupRow();
groupRow.MinHeight = 50;

columnGroupsView.ColumnGroups[columnGroupsView.ColumnGroups.Count - 1].Rows.Add(groupRow);

Should you have any other questions do not hesitate to ask.

Setting MinHeight do GridViewColumnGroupRow is working but... this also changed the height od filtering row and data rows (which is not intentional).

Hi Dominik,

You need to manually set the height of the rows. Here is  the code:

foreach (var item in grid.Rows)
{
   item.Height = 25;
}

Currently, this cannot be done for the new row and it should have the height of the group row.

I hope this will be useful.
