How can I display multiple lines of text in a column group header?  I can't see my "Line2" text in the sample below

 

public Form1()
    {
    InitializeComponent();
 
    ColumnGroupsViewDefinition view = new ColumnGroupsViewDefinition();
 
    List<String> cols = new List<string> () {"column2", "column3"};
    view.ColumnGroups.Add (CreateColGroup (cols, "Customer Contact"));
 
    view.ColumnGroups.Add(CreateColGroup(new List<string> (){"DNE", "column1"}, ""));
    this.radGridView1.ViewDefinition = view;
    }
 
private GridViewColumnGroup CreateColGroup (List<string> cols, string  groupName)
    {
    var colGroup = new GridViewColumnGroup(groupName);
    var groupRow = new GridViewColumnGroupRow();
    foreach (var colName in cols)
        {
        if (this.radGridView1.Columns[colName] != null)
            {
            groupRow.Columns.Add (this.radGridView1.Columns[colName]);
            }
        }
 
    foreach (var col in groupRow.Columns)
        {
        col.HeaderText += "\n  Line2";
        }
 
    colGroup.Rows.Add(groupRow);
 
    return colGroup;
    }

Hello Karl,

Thank you for writing.

You can set the MinHeight of the group row:
private GridViewColumnGroup CreateColGroup(List<string> cols, string groupName)
{
    var colGroup = new GridViewColumnGroup(groupName);
    var groupRow = new GridViewColumnGroupRow();
    foreach (var colName in cols)
    {
        if (this.radGridView1.Columns[colName] != null)
        {
            groupRow.Columns.Add(this.radGridView1.Columns[colName]);
        }
    }
 
    foreach (var col in groupRow.Columns)
    {
        col.HeaderText += "\n  Line2";
    }
    groupRow.MinHeight = 40;
    colGroup.Rows.Add(groupRow);
 
    return colGroup;
}

Or you can set the AutoSizeRows property of the grid:
radGridView1.AutoSizeRows = true;

Let me know if I can assist you further.

Setting the MinHeight works but AutoSizeRows = true appears to have no effect.

Forgot to mention this was with UI for WinForms Q1 2015. DLL version is 2015.1.331.20.

Hello Karl,

Thank you for writing back.

Yes, I can confirm that the AutoSizeRows would not work with the old version. If you want to use this feature you should upgrade to latest version. If you cannot upgrade you can use the MinHeight property.

Do not hesitate to contact us if you have other questions.

The MinHeight solution you provided changes all rows.  Is there any way to change just the height row height of the grouped column?

Hello Karl,

Thank you for writing back.

You can use the ViewRowFormatting event to set the height of all other rows:
void radGridView1_ViewRowFormatting(object sender, RowFormattingEventArgs e)
{
     e.RowElement.RowInfo.Height = 23;
}

I hope this will be useful.
