.cs
protected void gvImages_RowCommand（object sender，GridViewCommandEventArgs e）
{
试试
{
lbldel.Text =;
if（e.CommandName ==Remove）
{
GridViewRow row =（GridViewRow）（（Control）e.CommandSource） .NamingContainer;
//（或）//
// GridViewRow row =（GridViewRow）（（Control）e.CommandSource）.Parent.Parent;
index = row.RowIndex;
HiddenField id1 =（HiddenField）gvImages.Rows [index] .FindControl（ hf1）;
if（dbo.deleterecords（image，id =''+ id1.Value +''）== true ）
{
bindgrid（）;
lbldel.Text =图片已删除;
}
}
}
catch （例外情况）
{
例外E =前;
}
}
protected void gvImages_PageIndexChanging（object sender，GridViewPageEventArgs e）
{
try
{
gvImages.PageIndex = e.NewPageIndex;
bindgrid（）;
}
catch（例外情况）
{
}
}
public void bindgrid（）
{
尝试
{
DataTable dt = dbo.GetRecordsWithQuery（选择'''作为Sno，id，图像，''删除'作为[删除]来自图片）;
gvImages.DataSource = dt;
gvImages.DataBind（）;
}
catch（Exception ex）
{
Exception E = ex;
}
}
