Hi Hassan,
Thank you for your question.
You can achieve this by creating a custom cell element and use the
CellCreating event to incorporate it in
RadListView. The following code demonstrates this:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.radListView1.CellCreating += new Telerik.WinControls.UI.ListViewCellElementCreatingEventHandler(radListView1_CellCreating);
}
void radListView1_CellCreating(object sender, Telerik.WinControls.UI.ListViewCellElementCreatingEventArgs e)
{
if (e.CellElement.Data == this.radListView1.Columns[2] &&
!(e.CellElement is DetailListViewHeaderCellElement))
{
DetailListViewVisualItem item = (DetailListViewVisualItem)
typeof(DetailListViewDataCellElement).GetField("row", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(e.CellElement);
e.CellElement =
new LinkCellElement(item, e.CellElement.Data);
}
}
}
public class LinkCellElement : DetailListViewDataCellElement
{
public LinkCellElement(DetailListViewVisualItem item, ListViewDetailColumn column)
: base(item, column)
{ }
protected override void OnMouseDown(MouseEventArgs e)
{
base.OnMouseDown(e);
//do what you need on the clicked message
MessageBox.Show(this.Text);
}
public override void Synchronize()
{
base.Synchronize();
this.Image = GetImageForFileType(this.Text); // load your image depending on the extension
this.Font = new Font(this.Font, FontStyle.Underline);
this.ForeColor = Color.DarkBlue;
}
protected override Type ThemeEffectiveType
{
get
{
return typeof(DetailListViewDataCellElement);
}
}
}
Here we need to use reflection to get the row associated with the default cell, but in the next official releases we will introduce properties which will let you access them directly.
I hope this is useful. In case you have any additional questions, do not hesitate to write back.
Best wishes,
