Create dynamic photo gallery in asp.net using C#
Create Database in sql like this. There are two table
1. Album Table
2. Image Table (which are related with album table)
Sql Script
CREATE TABLE [dbo].[GroupImage](
[Id] [int] IDENTITY(1,1) NOT NULL,
[GroupName] [varchar](80) NOT NULL,
[Image] [varchar](200) NULL,
CONSTRAINT [PK__GroupIma__6EFCD4350F975522] PRIMARY KEY CLUSTERED
(
[GroupName] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
CREATE TABLE [dbo].[Image](
[Id] [int] IDENTITY(1,1) NOT NULL,
[GroupName] [varchar](80) NULL,
[Name] [varchar](50) NULL,
[Date] [varchar](30) NULL,
[Image] [varchar](200) NULL
) ON [PRIMARY]
Now add a folder with name of "GroupImage" in project folder.
Now add aspx page with name of GroupImage.aspx and add following script between head tag
<script type="text/javascript">
function fnConfirm() {
if (confirm("The item will be deleted. Are you sure want to continue?") == true)
return true;
else
return false;
}
</script>
<script type="text/javascript">
function previewFile() {
var preview = document.querySelector('#<%=Image1.ClientID %>');
var file = document.querySelector('#<%=fulImage_Group.ClientID %>').files[0];
var reader = new FileReader();
reader.onloadend = function () {
preview.src = reader.result;
}
if (file) {
reader.readAsDataURL(file);
} else {
preview.src = "";
}
}
</script>
Now add following code under body tag
<asp:ScriptManager ID="ScriptManager1" runat="server">
