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.
