Hello Team,
I try to set tooltip for combobox lineitem which is disabled , it is not showing tooltip, Is there any way to show tooltip while it disabled ? could you please help on this ASAP?
Please refer below code snippet and attached screenshot.
private void cmbPlugtype_VisualListItemFormatting(object sender, VisualItemFormattingEventArgs args)
{
if (cmbPlugtype.DropDownListElement.TextBox.Fill.BackColor != Color.Cyan)
{
args.VisualItem.ToolTipText = args.VisualItem.Data.DisplayValue.ToString();
}
else
{
args.VisualItem.Enabled = false;
args.VisualItem.ToolTipText = "It is Disabled".
}
}Thanks

Hello, Raj,
Tooltips cannot be displayed for disabled elements by design. The possible solution that I can suggest is to set the Enabled=true for all visual items, and set gray ForeColor to the items so that they look like as they are disabled.
I prepared a sample code snippet to demonstrate this approach:
private void RadDropDownList1_VisualListItemFormatting(object sender, VisualItemFormattingEventArgs args)
{
if (args.VisualItem.Text != "Item 0")
{
args.VisualItem.Enabled = true;
args.VisualItem.ForeColor = Color.Gray;
args.VisualItem.ToolTipText = "It is Disabled";
}
}

Hello, Raj,
It is not possible to set args.VisualItem.Selectable to false. Selectable property can be only get, not set. In my sample I mimic the gray look of the items, so they just look as disabled. To disable an item it requires setting Enabled=false which doesn't show a tooltip.
You can check the following thread from StackOverflow which shows other ideas: c# - Displaying tooltip over a disabled control - Stack Overflow
Please let me know if you have any other questions.
