SharePoint自定義控件(1)

 SPGridView中CheckBox TemplateField

由於SPGridView中沒有CheckBox列，所以需要我們自己開發，主要是實現ITemplate接口，然後添加一個CheckBox控件，並且在使用的時候指定是將這個CheckBox添加到Header上還是添加到Item上就可以了。具體代碼如下：

public class SPCheckboxTemplate : ITemplate
    {
        #region Fields
        private ListItemType mItemType;
        private string mColumnName = string.Empty;
        private string mNavUrl = string.Empty;
        private int mId = 0;
        #endregion

        /// <summary>
        /// Constructor
        /// </summary>
        /// <param name="itemType"></param>
        public SPCheckboxTemplate(ListItemType itemType)
        {
            mItemType = itemType;
        }

        #region ITemplate Methods

        /// <summary>
        /// Instantiate into the container
        /// </summary>
        /// <param name="container"></param>
        public void InstantiateIn(Control container)
        {
            Literal lt = new Literal();
            switch (mItemType)
            {
                case ListItemType.Item:
                    CheckBox itemBox = new CheckBox();
                    itemBox.ID = "CBItem" + mId.ToString();
                    itemBox.DataBinding += new EventHandler(CheckBox_DataBinding);
                    container.Controls.Add(itemBox);
                    break;
                case ListItemType.Header:
                    lt.Text = mColumnName;
                    CheckBox headerBox = new CheckBox();
                    container.Controls.Add(headerBox);
                    break;
            }
        }

        #endregion
    }

 

使用的方法如下：

 TemplateField checkBoxField = new TemplateField();
 checkBoxField.HeaderTemplate = new SPCheckboxTemplate(ListItemType.Header);

 checkBoxField.ItemTemplate = new SPCheckboxTemplate(ListItemType.Item);
 gridView.Columns.Add(checkBoxField);
