Hi Kenneth,
Currently,
RadListView does not support different column types, but you can achieve this using its events.
I am not sure if you want to use custom cells or custom editors. In case you want the third column to be edited by drop-down editors you can handle the
EditorRequired event the following way:
If you want to use visually customized cells, then you can use the
CellCreating event to apply your custom cell. Here is a short example:
public partial class Form45 : Form
{
public static ListViewDetailColumn checkBoxColumn;
public Form45()
{
InitializeComponent();
this.radListView1.CellCreating += new Telerik.WinControls.UI.ListViewCellElementCreatingEventHandler(radListView1_CellCreating);
checkBoxColumn = this.radListView1.Columns[2];
}
void radListView1_CellCreating(object sender, Telerik.WinControls.UI.ListViewCellElementCreatingEventArgs e)
{
DetailListViewDataCellElement cellElement = (e.CellElement as DetailListViewDataCellElement);
if (cellElement == null)
{
return;
}
DetailListViewVisualItem visualItem = this.radListView1.ListViewElement.ViewElement.GetElement(cellElement.Row) as DetailListViewVisualItem;
if (visualItem == null)
{
return;
}
if (e.CellElement.Data == checkBoxColumn)
{
e.CellElement = new CheckBoxCell(
visualItem,
e.CellElement.Data);
}
else
{
e.CellElement = new DefaultCell(
visualItem,
e.CellElement.Data);
}
}
}
public class CheckBoxCell : DetailListViewDataCellElement
{
private RadCheckBoxElement checkBox;
public CheckBoxCell(DetailListViewVisualItem owner, ListViewDetailColumn column)
: base(owner, column)
{
}
protected override void CreateChildElements()
{
base.CreateChildElements();
checkBox = new RadCheckBoxElement();
checkBox.StretchHorizontally = checkBox.StretchVertically = true;
this.Children.Add(checkBox);
}
public override void Synchronize()
{
base.Synchronize();
this.checkBox.Text = (string)this.Row[this.Data];
this.Text = "";
}
public override bool IsCompatible(ListViewDetailColumn data, object context)
{
return Form45.checkBoxColumn == data;
}
protected override Type ThemeEffectiveType
{
get
{
return typeof(DetailListViewDataCellElement);
}
}
}
public class DefaultCell : DetailListViewDataCellElement
{
public DefaultCell(DetailListViewVisualItem owner, ListViewDetailColumn column)
: base(owner, column)
{
}
public override bool IsCompatible(ListViewDetailColumn data, object context)
{
return Form45.checkBoxColumn != data;
}
protected override Type ThemeEffectiveType
{
get
{
return typeof(DetailListViewDataCellElement);
}
}
}
In this case it seems better to use
GridView instead, since it provides typed columns which you can use out of the box.
I hope this was helpful. Should you have further questions, do not hesitate to contact me.
