Error:Control cannot fall through from one case label ('case 2:') to another

Question

Hi,

   I am peresenting the data on the page using SPGridView.My requirement is i need to add add checkboxfield as a column to the existing SPGridView.For that what i have done is i have wrritten code as below in the web part as

 TemplateField checkboxCol = new TemplateField();
            checkboxCol.HeaderText = "Select All";
            checkboxCol.ItemTemplate = new CustomSPGridViewTemplate(ListItemType.Item, "Select All");
            spgw.Columns.Add(checkboxCol);
            this.Controls.Add(spgw);

in the CreateChildControls method.After that i have created another class and i have written as below

class CustomSPGridViewTemplate : ITemplate
    {
        ListItemType templateType;
        string columnName;
       
        public CustomSPGridViewTemplate(ListItemType type, string colname)
        {
            templateType = type;
            columnName = colname;
        }
        #region ITemplate Members

        public void InstantiateIn(Control container)
        {
            Literal lc = new Literal();
            switch (templateType)
            {
                case ListItemType.Header:
                    lc.Text = "<B>" + columnName + "</B>";
                    container.Controls.Add(lc);
                    break;
                case ListItemType.Item:
                    CheckBox checkBox = new CheckBox();
                    checkBox.ID = "SelectAllID";
                    checkBox.Visible = true;                   
                    //checkBox.DataBinding += new EventHandler(checkBox_DataBinding);
                    container.Controls.Add(checkBox);
            }
        }

But when i compile it is giving error as

'Control cannot fall through from one case label ('case 2:') to another'.Have you ever come across this scenario

Answer 1

You forgot the break statement in your second (last) case block.  The complier doesn't like that.  You code needs to be like :

case ListItemType.Header:
                    lc.Text = "<B>" + columnName + "</B>";
                    container.Controls.Add(lc);
                    break;
                case ListItemType.Item:
                    CheckBox checkBox = new CheckBox();
                    checkBox.ID = "SelectAllID";
                    checkBox.Visible = true;                   
                    //checkBox.DataBinding += new EventHandler(checkBox_DataBinding);
                    container.Controls.Add(checkBox);
                    break;
