Evening folks,
Need some help and hopefully there are some smarter ones here.

Basically, I need a date picker in a formview on an ASP.net C# page.

This is what I have come up with so far but just can't seem to get things to work correctly.

<asp:FormView ID="KeyDates_FV" runat="server" CellPadding="4" DataKeyNames="ID" DataSourceID="KeyDates_SQL" ForeColor="#333333" GridLines="Both" OnDataBound="KeyDates_FV_DataBound">
<edititemtemplate>
LAA_PlanDate:
<asp:TextBox ID="LAA_PlanDateTextBox" runat="server" Text='<%# Bind("LAA_PlanDate") %>' />
<asp:Calendar ID="LAA_PlanDate_CAL" runat="server" ForeColor="White" >

<asp:ImageButton ID="LAA_PlanDate_IMB" runat="server" ImageAlign="Bottom" ImageUrl="~/Images/Calendar_icon.png" Width="16px" />

What I have tried:

Thank you in advance for any help on this.

推荐答案

引用：

表单视图咆哮着我。 （对象引用未设置为对象的实例）。

the form view barks at me. (Object reference not set to an instance of an object).

您的FormView ID设置为KeyDates_FV并且在您的代码中，您正在使用 FormView1.FindControl（LAA_PlanDate_CAL）;



FormView1 首先不存在。所以你想做这样的事情：

Your FormView ID was set to "KeyDates_FV" and in your code, you are using FormView1.FindControl("LAA_PlanDate_CAL");

FormView1 doesn't exist in the first place. So you want to do something like this instead:

Calendar LAA_PlanDate_CAL = (Calendar)KeyDates_FV.FindControl("LAA_PlanDate_CAL");

Facepalm！捂脸！ Facepalm！



@Vincent Maverick非常感谢你！我觉得后面是一头奶牛的后端。我一直在桌子上敲了两个星期来解决这个问题。



谢谢！谢谢！谢谢！

Facepalm! Facepalm! Facepalm!

@Vincent Maverick THANK YOU SOOO MUCH! I feel like the hind end of a cows rear. I have been banging my head on the desk for two weeks to figure this out.

Thank you! Thank you! Thank you!
