Gridview - edititemtemplate标记问题 [英] Gridview - edititemtemplate tag problem

问题描述

我想要一个包含要编辑的文本框的Gridview，以及一个验证文本框值的Validate控件。但当我把两个控件放在< itemtemplate>下时标签我可以看到文本框但是如果我把它放在< edititemtemplate>下面标签我看不到文本框。



这是我的代码...



< pre lang =xml> < asp：TemplateField HeaderText = 排序顺序 SortExpression = Sort_Order meta：resourcekey = APPROVAL_STATUSResource >
< itemstyle width = 10％ horizo​​ntalalign = right > < / itemstyle >
< ; headerstyle width < span class =code-keyword> = 10％ horizo​​ntalalign = right > < / headerstyle >
< EditItemTemplate >
< asp：TextBox runat = server 文字 =' <％ #Bind（ Sort_Order）％> ' ID = txtSortOrder > < / asp：TextBo x >
< asp：CompareValidator ControlToValidate = txtSortOrder 运算符 = GreaterThanEqual 类型 = 整数 ValueToCompare = 0 ErrorMessage = 排序顺序字段不能为负数。 显示 = 无 runat = 服务器 / >
< / EditItemTemplate >
< / asp：TemplateField >

解决方案

 <   asp：TemplateField     HeaderText   =  StudentName      SortExpression   =  StudentName >  
 <   EditItemTemplate  >  
 <   asp：TextBox     ID   =  txtStudentName    runat   =  server   < span class =code-attribute>宽度  =  85px   文字  ='  <％ #Eval（   StudentName）％> '  /  >  
 <   / EditItemTemplate  >  
 
 <   ItemTemplate  >  
 <   asp：标签    ID   =  lblStudentName    runat   =  server   文字  ='  <％ #Eval（  StudentName ）％> '  /  >  
 <   / ItemTemplate  >  
 
 <   FooterTemplate  < span class =code-keyword>>  
 <   asp：TextBox     ID   =  txtFTRStudentName    runat   = 服务器   宽度  =  85px  /  >  
 <   asp：RequiredFieldValidator     ID   =  rfvStudentName    runat   =  server    ControlToValidate   =  txtFTRStudentName   文字  =  *    ValidationGroup   = 验证  /  < span class =code-keyword>>  
 <   / FooterTemplate  >  
 
 <   / asp：TemplateField  >  

当然，这对你有帮助。

Hi,

I want a Gridview which contains a textbox to edit and with a Validate control which will validate the text box value. But when I put the two controls under <itemtemplate> tag I can see the textbox but if I put the same under <edititemtemplate> tag I can''t see the textbox.

Here is my code...

<asp:TemplateField HeaderText="Sort Order" SortExpression="Sort_Order" meta:resourcekey="APPROVAL_STATUSResource">
     <itemstyle width="10%" horizontalalign="right"></itemstyle>
     <headerstyle width="10%" horizontalalign="right" ></headerstyle>
     <EditItemTemplate>
     <asp:TextBox runat="server" Text='<%#Bind("Sort_Order") %>' ID="txtSortOrder" ></asp:TextBox>
     <asp:CompareValidator ControlToValidate="txtSortOrder" Operator="GreaterThanEqual" Type="Integer" ValueToCompare="0" ErrorMessage="The Sort Order Field cannot be negative." Display="None" runat="server" />
     </EditItemTemplate>
</asp:TemplateField>

解决方案
