How do I get the width of a control ?

Dear NisseHt there are two ways to create a button 1.Using GUI 2.Code in both ways if you create a button without setting its "Width" and "Height" they are by default "0" and when you try to retrieve them as you did "double w=lb.Width.Value" here the value is also "0" Sol. To solve this problem to have to set the "Width" and "Height" properties manually. if you are using code you should try something like this Label lb = new Label(); System.Web.UI.WebControls.Unit newWidth = new System.Web.UI.WebControls.Unit(30) lb.Width = newWidth double w=lb.Width.Value; the "Width" property is from "System.Web.UI.WebControls.Unit" i.e "Width" is considered to be a "Unit", so we define a unit give it a value and then equal it with the "Width" property this way "w" is equal to "30" Incase of using GUI then simply in the property pane set the "Width" to "30" and your done. i hope this solves the problem
