根据其他值显示图像 [英] Display image based on another value

问题描述

我想根据另一个模板字段值显示图像。



示例人数（0010200）和保存在文件夹中的图像是00102000.jpg，如果是人数（ 01234）和保存在文件夹中的图像是01234.jpg等像这样我有很多员工图像。这全部保存在/ img / webfolder。



现在当永远lable2人数更改我需要更改image1，这将与人数相同，



请建议我实现相同。示例代码如下。



我尝试过：

I want to display image based on another templatefield value.

Example person num(0010200) and image saved in folder is 00102000.jpg , if person num(01234) and image saved in folder is 01234.jpg, etc. like this i have many employee images.and this all saved in /img/ webfolder.

Now when ever lable2 person num changes i need to change the image1 which will be same as person num,

please suggest me to achieve the same. example code below.

What I have tried:

<asp:TemplateField HeaderText="person_num" SortExpression="person_num">
<asp:BoundField DataField="full_name" HeaderText="full_name" SortExpression="full_name" />
<asp:TemplateField HeaderText="Image">

推荐答案

首先，我认为你想拥有你在问题中提出的场景中的一个小变化，即

First of all, I consider you want to have a small change in the scenario you have presented in the question i.e,

Quote：

示例人数（0010200）保存在文件夹中的图像是00102000.jpg，如果人数（01234）和保存在文件夹中的图像是01234.jpg

Example person num(0010200) and image saved in folder is 00102000.jpg , if person num(01234) and image saved in folder is 01234.jpg

它应该是

- - person_num = 0010200 then image = 0010200.jpg （注意：最后2个零而不是3，如问题所述，认为这是一个错字）

person_num = 01234 then image = 01234.jpg

- person_num = 0010200 then image = 00102000.jpg （注意：最后加1个零，与问题相同）

person_num = 01234 then image = 012340.jpg （最后加1个零）



第一种情况，如果您将图像保存为相同的na我作为person_num你可以使用以下代码而不添加任何其他逻辑。

It should be either
-- person_num = 0010200 then image = 0010200.jpg (note: 2 zeros at the end instead of 3 as stated in the question considering it to be a typo)
person_num = 01234 then image = 01234.jpg
-- person_num=0010200 then image = 00102000.jpg (note: 1 more zero added at the end, same as question)
person_num = 01234 then image = 012340.jpg (1 more zero added to at the end)

For the first case if you are saving the images as the same name as person_num you can use following code without any other logic added to it.

<itemtemplate headertext="Image">
     <img src="<%# Eval("person_num","~/Images/{0}.jpg") %>" <br="" mode="hold"> </itemtemplate>

第二种情况，你需要非常简单的改变，即

For the second case, you need just very simple change i.e,

<itemtemplate headertext="Image">
     <img src="<%# Eval("person_num","~/Images/{0}0.jpg") %>" <br="" mode="hold"> </itemtemplate>

如果你的要求是别的，请告诉我。

希望，它有帮助：）

Please let me know if your requirement is something else.
Hope, it helps :)

优秀......有些相同。我的结果几乎就是你的想法，



< asp：image id =Image2runat =serverimageurl =<％＃string.Format （ 〜/ IMG / {0} .JPG，评估和演示（ person_Num））％>中height =300width =300>

Excellent...some what same. and i got the result almost your idea,

<asp:image id="Image2" runat="server" imageurl="<%# string.Format("~/img/{0}.jpg",Eval("person_Num"))%>" height="300" width="300">
