Hello, Dilshod,
You can iterate all columns in
RadGridView and set the GridViewColumn.
WrapText property to
true. Thus, the cell values will be wrapped. In addition, you can use the demonstrated approach in the following help article showing how to autosize the entire row by measuring the content. For this purpose it is necessary to create a custom
GridDataRowElement:
https://docs.telerik.com/devtools/winforms/gridview/rows/how-to/autosize-entire-row
As a result, you will have the desired minimum height for the headers in the
ColumnGroupsViewDefinition and autosize the data rows as it is illustrated in the screenshot.
Here is a complete code snippet:
public RadForm1()
{
InitializeComponent();
this.radGridView1.CreateRow += radGridView1_CreateRow;
foreach (GridViewColumn col in this.radGridView1.Columns)
{
col.WrapText = true;
}
}
private void radGridView1_CreateRow(object sender, GridViewCreateRowEventArgs e)
{
if (e.RowType == typeof(GridDataRowElement))
{
e.RowType = typeof(CustomRowElement);
}
}
private void RadForm1_Load(object sender, EventArgs e)
{
this.customersTableAdapter.Fill(this.nwindDataSet.Customers);
ColumnGroupsViewDefinition view = new ColumnGroupsViewDefinition();
view.ColumnGroups.Add(new GridViewColumnGroup("Customer Contact"));
view.ColumnGroups.Add(new GridViewColumnGroup("Details"));
view.ColumnGroups[1].Groups.Add(new GridViewColumnGroup("Address"));
view.ColumnGroups[1].Groups.Add(new GridViewColumnGroup("Contact"));
view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[0].Rows[0].ColumnNames.Add("CompanyName");
view.ColumnGroups[0].Rows[0].ColumnNames.Add("ContactName");
view.ColumnGroups[0].Rows[0].ColumnNames.Add("ContactTitle");
view.ColumnGroups[1].Groups[0].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Groups[0].Rows[0].ColumnNames.Add("Address");
view.ColumnGroups[1].Groups[0].Rows[0].ColumnNames.Add("City");
view.ColumnGroups[1].Groups[0].Rows[0].ColumnNames.Add("Country");
view.ColumnGroups[1].Groups[1].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Groups[1].Rows[0].ColumnNames.Add("Phone");
view.ColumnGroups[1].Groups[1].Rows[0].ColumnNames.Add("Fax");
view.ColumnGroups[1].RowSpan = 100;
view.ColumnGroups[1].Groups[0].RowSpan = 50;
view.ColumnGroups[0].Rows[0].MinHeight = 30;
radGridView1.ViewDefinition = view;
}
public class CustomRowElement : GridDataRowElement
{
protected override Type ThemeEffectiveType
{
get
{
return typeof(GridDataRowElement);
}
}
protected override SizeF MeasureOverride(SizeF availableSize)
{
SizeF baseSize = base.MeasureOverride(availableSize);
CellElementProvider provider = new CellElementProvider(this.TableElement);
SizeF desiredSize = SizeF.Empty;
foreach (GridViewColumn column in this.ViewTemplate.Columns)
{
if (!this.IsColumnVisible(column))
{
continue;
}
GridDataCellElement cellElement = provider.GetElement(column, this) as GridDataCellElement;
this.Children.Add(cellElement);
if (cellElement != null)
{
cellElement.Measure(new SizeF(column.Width, float.PositiveInfinity));
if (desiredSize.Height < cellElement.DesiredSize.Height)
{
desiredSize.Height = cellElement.DesiredSize.Height;
}
}
cellElement.Detach();
this.Children.Remove(cellElement);
}
SizeF elementSize = this.TableElement.RowScroller.ElementProvider.GetElementSize(this.RowInfo);
int oldHeight = RowInfo.Height == -1 ? (int)elementSize.Height : RowInfo.Height;
this.RowInfo.SuspendPropertyNotifications();
this.RowInfo.Height = (int)desiredSize.Height;
this.RowInfo.ResumePropertyNotifications();
if (!this.RowInfo.IsPinned)
{
int delta = RowInfo.Height - oldHeight;
TableElement.RowScroller.UpdateScrollRange(TableElement.RowScroller.Scrollbar.Maximum + delta, false);
}
baseSize.Height = this.RowInfo.Height;
return baseSize;
}
private bool IsColumnVisible(GridViewColumn column)
{
return column.IsVisible;
}
}
I hope this information helps. If you have any additional questions, please let me know.
