无法在转发器ASP.NET中获取复选框选中的值 [英] Can't get checkbox checked value in repeater ASP.NET

问题描述

Aspx

Aspx

<asp:Repeater ID="rptOzellik" runat="server">
     <ItemTemplate>

      <div class="col-md-5 pad10">
         <asp:CheckBox ID="check" runat="server" />
         <asp:HiddenField ID="OzellikID" Value='<%#Eval("OzellikId") %>' runat="server" />

       </div>


     </ItemTemplate>
     </asp:Repeater>

代码背后：

Code Behind:

int[] OzellikIdArray = new int[rptOzellik.Items.Count];
         int i = 0;
         foreach (RepeaterItem item in rptOzellik.Items)
         {
             HiddenField OzellikID = (HiddenField)item.FindControl("OzellikId");
             var checkBox = (CheckBox)item.FindControl("check");
             if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
             {

                 if (checkBox.Checked)
                 {

                     OzellikIdArray[i] = int.Parse(OzellikID.Value.ToString());
                 }

             }
             i++;
         }

我勾选了几个复选框，但checkBox.checked总是返回false。

什么我错过了吗？

推荐答案

你应该做的是遍历控件，检查每个控件是否是一个复选框如果它是，并且具有正确的名称，请检查状态。

What you should do is to iterate through the controls, checking each to see if it is a checkbox.If it is, and has the right name, check the state.

我已经测试了您的代码，它的工作正常。

您必须移动内的数据绑定代码！Page.IsPostBack

I have tested your code, its working fine.
You will have to move the databinding code inside the !Page.IsPostBack

if (!Page.IsPostBack)
            {
                rptOzellik.DataSource = yourDataSource;
                rptOzellik.DataBind();
            }
