DX控件循环找控件

1、Ribbon循环查找  RibbonPage---RibbonPageGroup---BarButtonItem                               

 foreach (RibbonPage rPage in RPage_Home.Collection)

{

    foreach (RibbonPageGroup rpg in rPage.Groups)

    {

        foreach (var btn in rpg.Ribbon.Items)

        {

            if (btn is BarButtonItem)

            {

                BarButtonItem btnBar = btn as BarButtonItem;

                if (btnBar.Name.ToString() == strBtnRpg)

                {

                     btnBar.Visibility = DevExpress.XtraBars.BarItemVisibility.Always;

                }

            }

        }

    }

}

2、循环在layoutControlGroup里的LayoutControlItem sumItems[i]为一组控件名的集合（TextBox）

foreach (DevExpress.XtraLayout.LayoutControlItem item in layoutControlGroup02.Items)

{

    if (item.ControlName == sumItems[i])

    {

        item.Control.BackColor = Color.LightSalmon;

        values += item.Control.Text + "-";

    }

}

foreach (DevExpress.XtraLayout.LayoutControlItem item in layoutControlGroup01.Items)

{

   if (item.Control is TextEdit)

   {

      item.Control.Text = "";

   }

}

3、取出表中一行数据，循环赋值给LayoutControlItem中的TextEdit

DataRow dr = dt.Rows[0];

for (int i = 0; i < dr.ItemArray.Length; i++)

{

   foreach (DevExpress.XtraLayout.LayoutControlItem item in layoutControlGroup01.Items)

   {

      if (item.Text==dr.Table.Columns[i].ColumnName.ToString())

      {

         item.Control.Text = dr[dr.Table.Columns[i].ColumnName.ToString()].ToString();

      }

   }                   

}

4、将界面的LayoutControlItem中的TextEdit的数据循环赋值给特定行

//插入所有数据

               

                for (int i = 0; i < dr.ItemArray.Length; i++)

                {

                    foreach (DevExpress.XtraLayout.LayoutControlItem item in layoutControlGroup01.Items)

                    {

                        if (item.Text==dr.Table.Columns[i].ColumnName.ToString())

                        {

                            dr[dr.Table.Columns[i].ColumnName.ToString()] = item.Control.Text;

                            break;

                        }

                    }

                    foreach (DevExpress.XtraLayout.LayoutControlItem item in layoutControlGroup02.Items)

                    {

                        if (item.Text==dr.Table.Columns[i].ColumnName.ToString())

                        {

                            dr[dr.Table.Columns[i].ColumnName.ToString()] = item.Control.Text;

                            break;

                        }

                    }

                    foreach (DevExpress.XtraLayout.LayoutControlItem item in layoutControlGroup04.Items)

                    {

                        if (item.Text==dr.Table.Columns[i].ColumnName.ToString())

                        {

                            dr[dr.Table.Columns[i].ColumnName.ToString()] = item.Control.Text;

                            break;

                        }

                    }

                }

               

5.How to loop through all ribbon tabs, ribbon bar and items on WinForms Ribbon control

If you need to loop through all ribbon tabs, ribbon bars and items on each ribbon bar here is how to do it.

C#:

foreach (BaseItem item in ribbonControl1.Items)

{   

      RibbonTabItem ribbonTab = item as RibbonTabItem;   

      if (ribbonTab != null)   

      {       

         RibbonPanel panel = ribbonTab.Panel;       

         foreach (Control panelControl in panel.Controls)       

         {           

             RibbonBar ribbonBar = panelControl as RibbonBar;           

             if (ribbonBar != null)           

             {               

                // At this point you can simply disable each RibbonBar and that will                 //disable all items on it       

                //ribbonBar.Enabled = false;                

                // Here is how you loop through items on RibbonBar               

                foreach (BaseItem ribbonBarItem in ribbonBar.Items)               

                {                   

                     ribbonBarItem.Enabled = false;                

                }

              }

          }   

       }

}
