Question

GridView中编辑的时候，图片怎么绑定和上传

如题

Answer 1

可以直接用DataGrid控件与数据库绑定，数据库中存图片的绝对或者相对路径。
我这边也有一个图片绑定上传和删除的代码，你可以看一下，控件自己拖。
public partial class _Default : System.Web.UI.Page
{
private void setBind() {
DirectoryInfo info = new DirectoryInfo(Server.MapPath("images"));
this.DataListpic.DataSource = info.GetFiles();
this.DataListpic.DataBind();
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack) {

setBind();

}
}
protected void btn_delete_Click(object sender, EventArgs e)
{
foreach (DataListItem it in this.DataListpic.Items)
{
CheckBox cb = it.FindControl("cbx_delete") as CheckBox;

if (cb != null) {
if (cb.Checked) {
File.Delete(Server.MapPath("images/")+cb.Text);
}
}
}
setBind();

}

protected void btn_upload_Click(object sender, EventArgs e) {
if (this.FileUpload1.HasFile)
{
string name = this.FileUpload1.FileName;
this.FileUpload1.SaveAs(Server.MapPath("images/" + name));
Response.Write("上传成功!!");
setBind();
}
else
{
Response.Write("没有选中文件!!");
}
}

protected void DataListpic_SelectedIndexChanged(object sender, EventArgs e)
{
setBind();
}
}
