Dev Express之ImageComboBoxEdit,RepositoryItemImageComboBox使用方式

1.使用ImageComboBoxEdit实现下拉框键值数据函数

        public static void InitCmb(ImageComboBoxEdit cmb, DataTable source, string value, string text, bool isDefaultNull)

        {

            ImageComboBoxItem[] items = new ImageComboBoxItem[source.Rows.Count +];

            int i = ;

            if (isDefaultNull)

            {

                items[i] = new ImageComboBoxItem();

                items[i].Description = "";

                items[i].Value = "";

                items[i].ImageIndex = -;

                i++;

            }

            foreach (DataRow dr in source.Rows)

            {

                items[i] = new ImageComboBoxItem();

                items[i].Description = dr[text].ToString();

                items[i].Value = dr[value];

                items[i].ImageIndex = -;

                i++;

            }

            cmb.Properties.Items.Clear();

            cmb.Properties.Items.AddRange(items);

            cmb.EditValue = items[].Value;

        }

2.使用RepositoryItemImageComboBox实现GridControl内容Cell内下拉键值数据函数

        public static void InitCmb(RepositoryItemImageComboBox repImageComboBox, DataTable source,string value,string text,bool isDefaultNull)

        {

            ImageComboBoxItem[] items = new ImageComboBoxItem[source.Rows.Count+];

            int i=;

            if (isDefaultNull)

            {

                items[i] = new ImageComboBoxItem();

                items[i].Description = "";

                items[i].Value = "";

                items[i].ImageIndex = -;

                i++;

            }

            foreach (DataRow dr in source.Rows)

            {

                items[i] = new ImageComboBoxItem();

                items[i].Description = dr[text].ToString();

                items[i].Value = dr[value];

                items[i].ImageIndex = -;

                i++;

            }

            repImageComboBox.Items.AddRange(items);

        }

3.使用RepositoryItemImageComboBox/ImageComboBox与ImageCollection结合实现GridControl内容Cell内下拉图片数据函数

        public static void InitImgCmb(RepositoryItemImageComboBox repImageComboBox, DataTable source, string value, bool isDefaultNull)

        {

            ImageComboBoxItem[] items = new ImageComboBoxItem[source.Rows.Count + ];

            int i = ;

            if (isDefaultNull)

            {

                items[i] = new ImageComboBoxItem();

                items[i].Description = "";

                items[i].Value = "";

                items[i].ImageIndex = -;

                i++;

            }

            foreach (DataRow dr in source.Rows)

            {

                items[i] = new ImageComboBoxItem();

                items[i].Description = "";

                items[i].Value = dr[value];

                if(Int32.Parse(items[i].Value.ToString()) == ){

                    items[i].ImageIndex = ;

                }else if(Int32.Parse(items[i].Value.ToString()) == ){

                    items[i].ImageIndex = ;

                }else if(Int32.Parse(items[i].Value.ToString()) == ){

                    items[i].ImageIndex = ;

                }else if(Int32.Parse(items[i].Value.ToString()) == ){

                    items[i].ImageIndex = ;

                }else if(Int32.Parse(items[i].Value.ToString()) == ){

                    items[i].ImageIndex = ;

                }

                i++;

            }

            repImageComboBox.Items.AddRange(items);

        }
