[Solved] DropDownList in StatusStrip

Hello, Roy,

You can add RadDropDownListElement into RadStatusStrip.Items collection. Please refer to the following documentation article: Adding Items - RadStatusBar - Telerik UI for WinForms

Then, populate the drop down list with items: Adding Items Programmatically - WinForms DropDownList Control - Telerik UI for WinForms

I prepared a sample code snippet for your reference:

RadDropDownListElement ddl = new RadDropDownListElement();
ddl.MinSize = new Size(100, 0);
ddl.Items.Add(new RadListDataItem("item 1"));
ddl.Items.Add(new RadListDataItem("item 3"));
ddl.Items.Add(new RadListDataItem("item 3"));
this.radStatusStrip1.Items.Add(ddl);

I hope this information is useful. If you have any other questions do not hesitate to contact me.
