如何在网格外事件中获取网格视图中的单元格控件和数据? [英] how can i get a cell control and data in gridview in out of grid events?

问题描述

我有一个gridview，其中有2列(templateColumn)，第一个是复选框，第二个是复选框列表.该网格的行是从数据库创建的.每个复选框列表可以具有0到4个复选框，具体取决于数据库中的关系记录.

现在我的问题是，我有一个对象列表，每个对象都有0到4个相关记录.对于每个主要对象，必须检查其在网格中的相等性，然后在其关系记录中，应检查其在复选框列表中的相等性. 但是我无法访问网格外事件的行.
有我的代码:

i have a gridview that has 2 column (templateColumn)the frist is checkbox and the second in checkboxlist. this grid''s row is created from database. each checkboxlist can has 0 til 4 cheboxes depends on relation records in database.

now my broblem is that ,i have a listof object that each o them has 0 til 4 relational records. for each main object , it''s equal in grid must checked, and fore its relational records their equals in checkboxlist colum should checked.
but i can;t access to rows out of grid event.
there is my code :

<div  id="divMenuCapabilities" dir="rtl" align=right runat="server" style=" height:300px; overflow:scroll;">
        <asp:GridView ID="grid1" runat="server"  AutoGenerateColumns=false OnRowDataBound="grid1_OnRowDataBound"  >
              <Columns>
                 <asp:TemplateField  HeaderText="عنوان فرم">
                 <ItemTemplate>
                  <asp:CheckBox ID="CheckBox1" runat="server" text='<%#Eval("MenuItemName")%>' />
                   </ItemTemplate>
                  </asp:TemplateField>

                <asp:TemplateField HeaderText="قابلیت های فرم"  >
                  <ItemTemplate>
                    <asp:CheckBoxList runat="server" ID="cblCap"  RepeatDirection= "Horizontal"  />
                  </ItemTemplate>
                </asp:TemplateField>
                </Columns>
               </asp:GridView>
         </div>

private void FillGrid1()
       {
           ENTMenuItemEOList menuItemEoList = new ENTMenuItemEOList();
           menuItemEoList.LoadAll();
           ENTCapabilityEOList capabilityEoList = new ENTCapabilityEOList();
           capabilityEoList.Load();
           foreach (ENTMenuItemEO menuItemEo in menuItemEoList)
           {
               List<ENTCapabilityEO> entCapabilityEos = new List<ENTCapabilityEO>();
               entCapabilityEos = capabilityEoList.Where(cap => cap.ENTMenuItemId == menuItemEo.ID).ToList();
               menuItemEo.EntCapabilityEOListObject = entCapabilityEos;
           }

           grid1.DataSource = menuItemEoList;
           grid1.DataBind();

                 }

protected void Page_Load(object sender, EventArgs e)
      {
            if (!IsPostBack)
              {
                  string roleIdStr = Request.QueryString["id"];
                  int roleId = 0;
                  if (!string.IsNullOrEmpty(roleIdStr))
                  {
                      roleId = Convert.ToInt32(roleIdStr);
                  }

                  FillGrid1();
                  populateObjects(roleId);
              }
                         }

private void populateObjects(int id)
      {

ENTRoleCapabilityEOList roleCapList = new ENTRoleCapabilityEOList();
            roleCapList.LoadByRoleId(1);
            SetRoleCapToLvRoleCap(roleCapList);}

现在我想根据以下方法中的listof对象在两个列中选中一些复选框.但我不知道该怎么做.我无法在网格外事件中获得单元格控件.
请帮帮我.

now i want checked some checkboxes in both colums according to a listof object in below method. but i dont know how to do this. i can''t get cell control''s in out of grid event.
please help me.

private void SetRoleCapToLvRoleCap(ENTRoleCapabilityEOList selectedRoleCapList)
       {
           List<ENTMenuItemEO> menuItemEoList = (List<ENTMenuItemEO>) grid1.DataSource;
           foreach (ENTRoleCapabilityEO entRoleCapabilityEo  in selectedRoleCapList)
           {
               ENTCapabilityEO capabilityEo = new ENTCapabilityEO();
               capabilityEo.Load(entRoleCapabilityEo.ENTCapabilityId);


          
           }

推荐答案

为了迭代而不是使用GridView事件，您可以使用此代码

Hi,
In order to iterate instead of using GridView events you can use this code

foreach (GridViewRow grv in grid1.Rows)
{
   CheckBox CheckBox1=grv.FindControl("CheckBox1") as CheckBox;
   CheckBoxList cblCap = grv.FindControl("cblCap") as CheckBoxList;
}

现在，您可以应用验证逻辑，因为现在可以使用所有用户输入数据.

希望这会有所帮助.

Now you can apply your validation logics as all user input data is now available for you to use.

Hope this will help.
