找不到一个中继器的链接按钮 [英] Can't find a link button in a repeater

问题描述

我有一对夫妇数据绑定字段的中继器的链接按钮。我试图让我在哪里可以数据绑定但每次我尝试访问该链接按钮，我不断收到空返回之后设置按钮的OnClientClick。

I have a link button in a repeater with a couple of databound fields. I'm trying to get to where I can set the buttons onClientClick after the databinding however everytime I try to access the link button I keep getting Null returned.

我已经通过涉及中继器和控制这里的每一个问题，看了看，一直没能弄明白。

I've looked through every single question involving repeaters and controls here and haven't been able to figure it out.

在.aspx

    <asp:Repeater ID="DailyRepeater" OnItemCommand="DailyRepeater_ItemCommand" runat="server">
                    <HeaderTemplate>
                        <tr>
                            <td class="coltitle">
                                Time
                            </td>
                            <td class="coltitle">
                                Activity
                            </td>
                            <td class="coltitle">
                                Hours
                            </td>
                        </tr>
                    </HeaderTemplate>
                    <ItemTemplate>
                        <tr class="evenrow">
                            <td>
                                <%# Eval("StartTime","{0:HH:mm}") %>-<%# Eval("EndTime","{0:HH:mm}") %>
                            </td>
                            <td>
                                <%# Eval("Description") %>
                            </td>
                            <td>
                                <%# Eval("Hours","{0:0.0}") %>
                            </td>
                            <td>
                                   <asp:LinkButton runat="server" CausesValidation="false" ID="editbutton" Text="Edit">Edit</asp:LinkButton>
                            </td>
                        </tr>
                    </ItemTemplate>

在.aspx.cs

The .aspx.cs

    protected void DailyRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        LinkButton myButton = (LinkButton)e.Item.FindControl("editbutton");
        myButton.OnClientClick = (popupWindow.GetTargetPopupCode("URL");
    }

从我读过，我应该能够得到使用RepeaterItemEventargs按钮。不过，我似乎无法在这里找到它。我想起了另一件事是不是由这件事发生的时间（这是没有意义是因为这是一个数据绑定的事件）发生的结合，但由于某种原因，e的回来e.Item有一个零和的DataItem的-1的ItemIndex ...

From what I've read, I should have been able to get to the button using the RepeaterItemEventargs. However I can't seem to find it here. The other thing I thought of was that the binding wasn't happening by the time this happened (which made no sense to be as this is a databound event) but for some reason e is coming back e.Item has a dataItem of null and an itemIndex of -1...

我只是真的很困惑，失去了任何帮助将大大AP preciated。

I'm just really confused and lost any help would be greatly appreciated.

谢谢！

推荐答案

这听起来像你还没有对项目类型把守。通常情况下，它触发头，所有的项目，然后页脚。你需要做的是：

It sounds like you haven't guarded against the item type. Typically, it fires the header, all the items, and then the footer. You need to do this:

 if(e.Item.ItemType == ItemType.Item || e.Item.ItemType == ItemType.AlternatingItem)
 {
      LinkButton myButton = (LinkButton)e.Item.FindControl("editbutton");
      myButton.OnClientClick = (popupWindow.GetTargetPopupCode("URL");
 }
