我们可以有这样的图片网址吗 [英] Can we have imageurl like this

问题描述

大家好

我想在gridview中的imagebutton的imageurl中具有评估功能.
但这会带来编译时间.我们可以这样吗?如果是的话，语法是什么?

Hi All

I want to have eval funtionality in imageurl of imagebutton which is in gridview.
But it throws compile time. Can we have like this.If so what is the syntax?

<asp:ImageButton ID="imgActivate" runat="server" ImageUrl='<%#DataBinder.Eval(Container.DataItem, "picturename")?"/Images/Active.PNG":"/Images/InActive.PNG" %>'

                                            OnClick="imgActivate_Click"  OnCommand="imgActivate_Command" CommandArgument='<%# Eval("UserId") %>'

                                            CommandName="Activate"  />

问候

推荐答案

不，这不起作用.服务器标记中不能包含代码块.

No, this wont work. You cant have code blocks in server tags.

But you should better get the URL in code behind.

您可以按照以下方式进行操作.

hi you can do that in the Following Way.

<asp:TemplateField HeaderText="Small Image">
                                       <ItemTemplate>
                                           <asp:Image ID="imgPlacesSmallImage" ImageUrl='<%# String.Concat(@"~\Uploads\PlaceImages\SmallImage\",Eval("placetovisitimages_image")) %>' AlternateText="N.A"

                                               Width="25%" Height="15%" runat="server" />
                                       </ItemTemplate>
                                       <ItemStyle Width="30%" HorizontalAlign="Center" />
                                   </asp:TemplateField>
