Hi Alex,
Thank you for using Syncfusion product.
You can increase width of the controlbar by using Size property. If you set the size, control bar automatically resizes the controls which are placed inside of it.
Kindly refer the code snippet:
this.controlBar1.Size = new Size(300, 300);
Please look into the sample and let me know if it helps:
