Hello, Tim,
RadChat allows you to create custom items and add any element that you need in the chat messages. A sample approach is demonstrated in the following help article:
https://docs.telerik.com/devtools/winforms/chat/customizing-appearance/custom-items
When you need to offer the user a list of options, the
ChatListOverlay is the appropriate solution as you can select an item from a predefined list of choices. If you wish to display a
RadMultiColumnComboBox you can create a custom
ChatListOverlay. a sample approach is demonstrated in the following code snippet:
public RadForm1()
{
InitializeComponent();
CustomBaseChatItemOverlay listOverlay = new CustomBaseChatItemOverlay("List overlay");
DataTable dt = new DataTable();
dt.Columns.Add("Id", typeof(int));
dt.Columns.Add("Name", typeof(string));
for (int i = 0; i < 10; i++)
{
dt.Rows.Add(i, "Item" + i);
}
listOverlay.Mccb.DisplayMember = "Name";
listOverlay.Mccb.ValueMember = "Id";
listOverlay.Mccb.DataSource = dt;
bool showAsPopup = false;
Author author = new Author(Properties.Resources.AndrewFuller, "Andrew");
this.radChat1.Author = author;
ChatOverlayMessage overlayMessage = new ChatOverlayMessage(listOverlay, showAsPopup, author, DateTime.Now);
this.radChat1.AddMessage(overlayMessage);
}
public class CustomBaseChatItemOverlay : BaseChatItemOverlay
{
public CustomBaseChatItemOverlay(string title) : base(title)
{
this.mccb.SelectedValueChanged += mccb_SelectedValueChanged;
}
public RadMultiColumnComboBox Mccb
{
get
{
return this.mccb;
}
}
private void mccb_SelectedValueChanged(object sender, EventArgs e)
{
if (this.mccb.SelectedItem != null)
{
this.CurrentValue = this.mccb.SelectedValue;
}
}
RadMultiColumnComboBox mccb;
protected override Telerik.WinControls.RadElement CreateMainElement()
{
mccb = new RadMultiColumnComboBox();
return new RadHostItem(this.mccb);
}
protected override void DisposeManagedResources()
{
this.mccb.SelectedValueChanged -= mccb_SelectedValueChanged;
base.DisposeManagedResources();
}
}
I hope this information helps. If you have any additional questions, please let me know.
Regards,
Dess
