ColumnGroupsView height

[konrad]

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.

Sorry, is this solution still the only valid today? I haven't found anything else about it.

According to the provided information, it seems that you are using ColumnGroupsViewDefinition. The GridViewColumnGroupRow offers the MinHeight property which controls the minimum height of the row. If the property is not set, the row height will be equal to the maximum RowSpan of the columns in that row. On the other hand, the GridViewColumnGroup offers the RowSpan property that controls the vertical span of the group (the height) in pixels.

columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup("Group 1 Line 1" + Environment.NewLine + "Group 1 Line 2") { RowSpan= 100});

You can consider using the RowSpan property.

Thanks Dinko,
I was referring to the possibility of sizing the data rows (through rowHeigth and RowSpan) independently from the other rows (headers and more) and in the presence of groups of columns. In my case I resized the rows by looping through each row in the rowschanged event.

What else you can try is to subscribe to the RowFormatting event of the RadGridView which will be called for each data row. You can get the row element from the event arguments and change its height depending on your requirement.

private void RadGridView1_RowFormatting(object sender, RowFormattingEventArgs e)
{
    e.RowElement.RowInfo.Height = 10;
}

thank you Dinko.

Not the perfect solution but I will use it. :) Thanks!
