GridView的EditItemTemplate中的HTML輸入控件

我在EditItemTemplate的Gridview中有一個HTML輸入日期控件。我現在面臨的問題是，在編輯模式下的控制是數據綁定GridView的EditItemTemplate中的HTML輸入控件

<asp:TemplateField HeaderText="Date Of Publication" SortExpression="DateOfPublication"> 
        <EditItemTemplate> 
         <input id="tbDateOfPublicationEdit" runat="server" type="text" placeholder="Date Of Publication" title="Date Of Publication" 
          value='<%# Item.DateOfPublication == null ? "" : Item.DateOfPublication.Value.ToShortDateString() %>' />           
        </EditItemTemplate>

整個GridView的是這裏

<asp:GridView ID="gvAttachments" runat="server" AutoGenerateColumns="False" CellPadding="5" class="table" ItemType="Form_Attachment"

在''<％＃Bind（Item.DateOfPublication）== null中使用'Bind'或'Eval'？「」：綁定（Item.DateOfPublication.Value.Date.ToString（））％>'' – Curiousdev

我們不能，如果我們使用EF特徵項 – shomaail

使用EVAL或BIND可能你是對的，但如果你使用的是EF比我們可以使用'Eval'而不是'Bind''查找[this]（http://stackoverflow.com/a/9740818/2534646）鏈接可能會幫助你 – Curiousdev

嘗試更改日期選擇器沒有出現

<input id="tbDateOfPublicationEdit" runat="server" type="text" placeholder="Date Of Publication" title="Date Of Publication"

到

<input id="tbDateOfPublicationEdit" runat="server" type="date" placeholder="Date Of Publication" title="Date Of Publication"

與類型=「日期」日期選擇器出現但不是在綁定完成時 – shomaail
