错误属性'itemtemplate'没有名为'commandname'的属性 [英] Error property 'itemtemplate' does not have a property named 'commandname'

问题描述

我尝试添加comandname但它不起作用

我再问一遍前一个问题未答复



我有什么试过：

 <   asp：TemplateField       HeaderText   =' < img width =20pxheight =20pxsrc = ../Images/updown.png\"/>Id'     ItemStyle-Horizo​​ntalAlign   = 中心     >  
 <   itemtemplate     commandname   = 排序     commandargument   = < span class =code-keyword> myDBfield >  <％ #Container .DataItemIndex + 1 ％>  <   / itemtemplate  >  
 
 
 <   asp：BoundField     HtmlEncode   =  false    DataField   =  LoanType    HeaderText   =' < img src =../ Images / updown.png/> LoanType'    SortExpression   =  LoanType    /  >  
 <   asp：BoundField     DataField   =  LoanTerm    HeaderText   =  Term（Years）    SortExpression   =  LoanTerm    /  >  
 <   asp：BoundField     DataField   =  LoanRate    HeaderText   =  LoanRate < span class =code-attribute>   SortExpression   =  LoanRate    /  > ;  
 <   asp：BoundField     DataField   =   LoanAvailableFrom    HeaderText   = 贷款可用于    SortExpression   =  LoanAvailableFrom    /  >  
 <   asp：BoundField     DataField   =  LoanAvailableTo    Hea derText   = 贷款可用于    SortExpression   =  LoanAvailableTo    /  >  
 < span class =code-keyword><   asp：CommandField     HeaderText   = 编辑    SelectText   = 编辑     ShowSelectButton   = < span class =code-keyword> True    /  >  
 <   asp：CommandField     HeaderText   = 删除    ShowDeleteButton   =  True    ShowHeader   =  True     /  >  

解决方案

错误信息非常明显 - ItemTemplate a TemplateField 字段 [ ^ ]不包含名为<$ c的属性$ c> CommandName 或 CommandArgument 。它只是一个占位符，可以显示在该列中的任何内容。



如果您希望列中的值可以点击，那么您需要添加一个按钮或 LinkBut​​ton 到模板：

 <   asp：TemplateField       ...  >  
 < span class =code-keyword><   ItemTemplate  >  
 <   asp：按钮    runat   =  server  
   
  < span class =code-attribute>                         CommandName   = 排序    
   
                          < span class =code-attribute> CommandArgument   =  myDBfield  
   
                          文字  ='  <％ #Container.DataItemIndex +  1  < span class =code-pagedirective>％> '  
   
        < span class =code-attribute>           /  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField   >  

如果您希望列可以排序，那么设置 SortExpression 属性 TemplateField ：

 <  <温泉n class =code-leadattribute> asp：TemplateField       ...     SortExpression   =  myDBfield >  
 <   ItemTemplate  >  
 <％ #Container.DataItemIndex +  1  ％>  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  > < /跨度> 

I tried adding comandname but it does not work
I am asking again as previous question unanswered

What I have tried:

<asp:TemplateField  HeaderText='<img width="20px" height="20px" src="../Images/updown.png"/>Id'  ItemStyle-HorizontalAlign="Center"  >
    <itemtemplate commandname="Sort" commandargument="myDBfield"><%#Container.DataItemIndex+1%></itemtemplate>
    
                   
    <asp:BoundField HtmlEncode="false" DataField="LoanType" HeaderText='<img  src="../Images/updown.png"/>LoanType' SortExpression="LoanType" />
    <asp:BoundField DataField="LoanTerm" HeaderText="Term(Years)" SortExpression="LoanTerm" />
    <asp:BoundField DataField="LoanRate" HeaderText="LoanRate" SortExpression="LoanRate" />
    <asp:BoundField DataField="LoanAvailableFrom" HeaderText="Loan Available From" SortExpression="LoanAvailableFrom" />
    <asp:BoundField DataField="LoanAvailableTo" HeaderText="Loan Available To" SortExpression="LoanAvailableTo" />
    <asp:CommandField HeaderText="Edit" SelectText="Edit" ShowSelectButton="True" />
    <asp:CommandField HeaderText="Delete" ShowDeleteButton="True" ShowHeader="True" />

解决方案

The error message is pretty self-explanatory - the ItemTemplate for a TemplateField field[^] doesn't contain properties called CommandName or CommandArgument. It's just a placeholder for whatever you want to appear in that column.

If you want the values in the column to be clickable, then you'll need to add a Button or LinkButton to the template:

<asp:TemplateField  ...>
    <ItemTemplate>
        <asp:Button runat="server"

            CommandName="Sort" 

            CommandArgument="myDBfield"

            Text='<%# Container.DataItemIndex + 1 %>'

        />
    </ItemTemplate>
</asp:TemplateField>

If you want the column to be sortable, then set the SortExpression property on the TemplateField:

<asp:TemplateField  ... SortExpression="myDBfield">
    <ItemTemplate>
        <%# Container.DataItemIndex + 1 %>
    </ItemTemplate>
</asp:TemplateField>
