在数据库Asp.net C＃SQL中插入文件名时将图像上传到文件夹

Question

so started using a new method for dynamicly displaying images inserted into my database. This is the asp.net code

<asp:ImageButton ID="ImageButton1" ImageUrl='<%#Eval ("ImageUrl", "~/img/{0}") %>' Width="200px" PostBackUrl='<%#Eval ("ProductID", "Product.aspx?ProductID={0}") %>' runat="server" />

now, as you can see what it does is getting the "ImageUrl" from my database depending on what the ProductID is, and then shows that as the image url. Example in my folder /img/ i have a picture called "pic.jpg" then this code would make the image url "~/img/Pic.jpg" now how would i add a new image into the table from the backend? i would have to make a flileupload control upload the file to the "img" folder and then insert only the file name as the "ImageUrl" in the database table. How is this done? do you have any examples or can point me in the right direction?

thanks!

all answers appreciated!

Answer 1

ImageButton is actually a html input type image. So you should not use it for just display purposes. You can use Image control or even use html img tag.
