[Solved] GridViewTableDefinition set Height.

[Andrew Newton]

Hi.I have created dynamically hierarchial grid.I want to set GridViewTableDefinition's height. Is it possible?

Here my code.

 RadGridView rgd = GeneratedGrid();  
rgd.TableDefinition.PreviewDataRecordCreate += this.MasterTableDefinition_PreviewDataRowCreate;
rgd.ItemsSource = e.Result;  
grdMainGrid.Children.Add(rgd);
RadGridView1 = rgd;
RadGridView1.Loaded += new RoutedEventHandler(RadGridView1_Loaded);
ExpandRows();

#region Data Bind

RadGridView GeneratedGrid()
{
RadGridView rgd = new RadGridView();
rgd.Name = "RadGridView1";
rgd.HorizontalAlignment = HorizontalAlignment.Center;
rgd.VerticalAlignment = VerticalAlignment.Top;
rgd.IsReadOnly = true;
rgd.RowIndicatorVisibility = Visibility.Collapsed;
rgd.AutoGenerateColumns = false;
rgd.ColumnsWidthMode = ColumnsWidthMode.Fill;
rgd.CanUserFreezeColumns = false;
rgd.Width = LayoutRoot.Width - 10;
rgd.Height = LayoutRoot.Height - 30;
rgd.MaxHeight = LayoutRoot.Height;  

GridViewDataColumn column = new GridViewDataColumn();
column.DataMemberBinding = new Binding("OwnerID");
column.Header = "Owner Ref";
column.IsFilterable = false;
rgd.Columns.Add(column);

column = new GridViewDataColumn();
column.DataMemberBinding = new Binding("OwnerName");
column.Header = "Owner Name";
column.IsFilterable = false;
rgd.Columns.Add(column);

column = new GridViewDataColumn();
column.DataMemberBinding = new Binding("OwnerPhone");
column.Header = "Phone";
column.IsFilterable = false;
rgd.Columns.Add(column);

column = new GridViewDataColumn();
column.DataMemberBinding = new Binding("OwnerEmail");
column.Header = "Email";
column.IsFilterable = false;
rgd.Columns.Add(column);

ButtonDataColumn columnbtn = new ButtonDataColumn() { Content = "Add Rental",ButtonClick = new RoutedEventHandler(AddRentalButton_Click),ButtonWidth= 105};
columnbtn.DataMemberBinding = new Binding("LongTermRentalID");
columnbtn.Width = new GridLength(100);
columnbtn.Header = "";
columnbtn.IsFilterable = false;
rgd.Columns.Add(columnbtn);

return rgd;
}

Hi Andrew Newton,

In order to modify the height of the child grid, you will need to define an explicit HierarchyChildTemplate for the master grid and configure the the height. To see how to define a HierarchyChildTemplateplease take a look at this example.

Please, let me know if you are not trying to increase the height of the child grid as a I understand from your ticket.

All the best,
