c＃將複選框colum添加到GridViewColum WPF

Question

我想添加一個CheckboxColum到Gridview，我完全卡住了。我不會在WPF工作

var gridView = new GridView(); 

GridViewColumn col = new GridViewColumn(); 

col.Header = "Colum "; 
col.Width = 100; 
col.CellTemplate = (DataTemplate) ...... 
col.DisplayMemberBinding = new Binding("BooleanData"); 
gridView.Columns.Add(col); 

我卡在這裏

col.CellTemplate = (DataTemplate) CheckBox .... 

Answer 1

你只需要改變這一行...

GridViewColumn col = new GridViewColumn(); 

這個（的WinForms）

CheckBoxColumn checkCol = new CheckBoxColumn(); 

或此（WPF）

CheckBoxColumn checkCol = new DataGridCheckBoxColumn(); 

這裏是所有列類型的列表 http://msdn.microsoft.com/en-us/library/bxt3k60s.aspx

創建具有如下代碼的類：

using System; 
using System.Data; 
using System.Configuration; 
using System.Web; 
using System.Web.Security; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using System.Web.UI.WebControls.WebParts; 
using System.Web.UI.HtmlControls; 
using System.ComponentModel; 
using System.Collections; 
/// <summary> 
/// Summary description for DynamicTemplate 
/// </summary> 
public class DynamicTemplate : System.Web.UI.ITemplate 
{ 
public String TableName { get; set; } 

System.Web.UI.WebControls.ListItemType templateType; 
System.Collections.Hashtable htControls = new System.Collections.Hashtable(); 
System.Collections.Hashtable htBindPropertiesNames = new System.Collections.Hashtable(); 
System.Collections.Hashtable htBindExpression = new System.Collections.Hashtable(); 

public DynamicTemplate(System.Web.UI.WebControls.ListItemType type) 
{ 
    templateType = type; 
} 

public void AddControl(WebControl wbControl, String BindPropertyName, String BindExpression) 
{ 
    htControls.Add(htControls.Count, wbControl); 
    htBindPropertiesNames.Add(htBindPropertiesNames.Count, BindPropertyName); 
    htBindExpression.Add(htBindExpression.Count, BindExpression); 
} 

public void AddControl(HtmlControl wbControl, String BindPropertyName, String BindExpression) 
{ 
    htControls.Add(htControls.Count, wbControl); 
    htBindPropertiesNames.Add(htBindPropertiesNames.Count, BindPropertyName); 
    htBindExpression.Add(htBindExpression.Count, BindExpression); 
} 

public void InstantiateIn(System.Web.UI.Control container) 
{ 
    PlaceHolder ph = new PlaceHolder(); 

    for (int i = 0; i < htControls.Count; i++) 
    { 
     //clone control 
     Control cntrl = CloneControl((Control)htControls[i]); 

     switch (templateType) 
     { 
      case ListItemType.Header: 
       break; 
      case ListItemType.Item: 
       ph.Controls.Add(cntrl); 
       break; 
      case ListItemType.AlternatingItem: 
       ph.Controls.Add(cntrl); 
       ph.DataBinding += new EventHandler(Item_DataBinding); 
       break; 
      case ListItemType.Footer: 
       break; 
     } 
    } 
    ph.DataBinding += new EventHandler(Item_DataBinding); 
    container.Controls.Add(ph); 
} 
public void Item_DataBinding(object sender, System.EventArgs e) 
{ 
    PlaceHolder ph = (PlaceHolder)sender; 
    GridViewRow ri = (GridViewRow)ph.NamingContainer; 
    for (int i = 0; i < htControls.Count; i++) 
    { 
     if (htBindPropertiesNames[i].ToString().Length > 0) 
     { 
      Control tmpCtrl = (Control)htControls[i]; 

      String item1Value = GetType(htBindExpression[i].ToString(), ri); 

      //Guid value = new Guid(DataBinder.Eval(ri.DataItem, htBindExpression[i].ToString()).ToString()); 
      //String valueString = value.ToString(); 
      //item1Value = item1Value1.ToString(); 

      Control ctrl = ph.FindControl(tmpCtrl.ID); 
      Type t = ctrl.GetType(); 
      System.Reflection.PropertyInfo pi = t.GetProperty(htBindPropertiesNames[i].ToString()); 
      if (pi != null) 
      { 
       pi.SetValue(ctrl, item1Value.ToString(), null); 
      } 
     } 
    } 
} 

private String GetType(String ColumnName, GridViewRow row) 
{ 
    String Result = ""; 
    clsSearch obj = new clsSearch(); 
    // i have set up the table name static as now we require to make search working for macintosh project only. 
    // as per rakesh sir directed. 
    Int32 Type = obj.GetNumberForDataTypeofColumn("tblProperty", ColumnName); 
    switch (Type) 
    { 
     case 1: 
      DateTime dtvalue = (DateTime)DataBinder.Eval(row.DataItem, ColumnName); 
      Result = dtvalue.ToString(); 
      break; 
     case 2: 
      String svalue = (String)DataBinder.Eval(row.DataItem, ColumnName); 
      Result = svalue; 
      break; 
     case 3: 

      break; 
     case 4: 
      Int32 ivalue = (Int32)DataBinder.Eval(row.DataItem, ColumnName); 
      Result = ivalue.ToString(); 
      break; 
     case 5: 
      Guid gvalue = (Guid)DataBinder.Eval(row.DataItem, ColumnName); 
      Result = gvalue.ToString(); 
      break; 
    } 

    return Result; 
} 

private Control CloneControl(System.Web.UI.Control src_ctl) 
{ 
    Type t = src_ctl.GetType(); 
    Object obj = Activator.CreateInstance(t); 
    Control dst_ctl = (Control)obj; 
    PropertyDescriptorCollection src_pdc = TypeDescriptor.GetProperties(src_ctl); 
    PropertyDescriptorCollection dst_pdc = TypeDescriptor.GetProperties(dst_ctl); 

    for (int i = 0; i < src_pdc.Count; i++) 
    { 
     if (src_pdc[i].Attributes.Contains(DesignerSerializationVisibilityAttribute.Content)) 
     { 
      object collection_val = src_pdc[i].GetValue(src_ctl); 
      if ((collection_val is IList) == true) 
      { 
       foreach (object child in (IList)collection_val) 
       { 
        Control new_child = CloneControl(child as Control); 
        object dst_collection_val = dst_pdc[i].GetValue(dst_ctl); 
        ((IList)dst_collection_val).Add(new_child); 
       } 
      } 
     } 
     else 
     { 
      dst_pdc[src_pdc[i].Name].SetValue(dst_ctl, src_pdc[i].GetValue(src_ctl)); 
     } 
    } 

    return dst_ctl; 

} 

}

，並使用它像下面：

TemplateField t = new TemplateField(); 
      DynamicTemplate mt = new DynamicTemplate(ListItemType.Item); 

      mt.TableName = TableName; 
      if (IsEditButtonVisible == 1) 
      { 
       Image ibtnEdit = new Image(); 
       ibtnEdit.ID = "btnEdit"; 
       ibtnEdit.CssClass = "EditButton"; 
       ibtnEdit.ImageUrl = EditButtonImageSrc; 
       ibtnEdit.Style.Add("cursor", "pointer"); 
       ibtnEdit.ToolTip = "View Details"; 
       mt.AddControl(ibtnEdit, "AlternateText", "Id"); 
      } 
      if (IsDeleteButtonVisible == 1) 
      { 
       Image ibtnDelete = new Image(); 
       ibtnDelete.ID = "ibtnDelete"; 
       ibtnDelete.CssClass = "DeleteButton"; 
       ibtnDelete.ImageUrl = DeleteButtonImageSrc; 
       mt.AddControl(ibtnDelete, "AlternateText", "Id"); 
      } 
      t.ItemTemplate = mt; 
      t.HeaderText = "Activity"; 
      t.HeaderStyle.HorizontalAlign = HorizontalAlign.Left; 
      GridView1.Columns.Add(t); 
     } 
     GridView1.DataSource = dtOutPutResult; 
     GridView1.DataBind(); 

我正在添加按鈕在相同的，你可以做複選框
