现在我在asp.net中使用了HTml编辑器控件然后我在控件中复制了粘贴图像，然后在点击提交按钮后将其存储在sqlserver中的表。



但是当我尝试在gridview中显示图像数据时，无法在gridview中显示iamge。

< cc1：编辑ID =   edQuestions runat =   server宽度=   92％ AutoFocus =   false 
可见=   true高度=   200px IgnoreTab =   True /&g t; 

这里存储的数据在sqlserver的单列中：



< img alt =src =data：image / png; base64，iVBORw0KGgoAAAANSUhEUgAAAOsAAAB6CAIAAADRUjNkAAAXFklEQVR4nO2d VNa2bbH / ddSdVOdup0Y4QgOvOqKVddnPbtS19y />这是测试



gridview中的显示格式，但不能显示图像

<％ #Eval（问题）％>



请有人知道告诉我。

谢谢

解决方案

图像保存到数据库的格式是什么？就像将图像转换为字节并保存/只是图像路径保存到数据库一样。您可以通过一种或另一种方式查看此示例让你的问题得到解决

Hi,

Now I have used HTml Editor controls in asp.net then I copy paste image with text in controls then After Click submit button it is stored in table in sqlserver.

But when i try to display data in gridview with image data, Can't display iamge in gridview.

Ex:

<cc1:Editor ID="edQuestions" runat="server" Width="92%" AutoFocus="false"
                                        Visible="true" Height="200px" IgnoreTab="True"/>

Here stored data in single column in sqlserver:

" <img alt="" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAOsAAAB6CAIAAADRUjNkAAAXFklEQVR4nO2d VNa2bbH/ddSdVOdup0Y4QgOvOqKVddnPbtS19y/> this is the test "

Display format in gridview, but can't diplay image
<%# Eval("Questions") %>

Please anybody knows tell me.
Thanks

解决方案

What is the format the image is saved to data base? like you converting image to byte and saving/ just image path is saving to database. one or the other way you can look in to this example and get your issue solved
