Thubnail images should display with out any change in Quality i.e by DataList Control
On Click of Thubnail images Fullview of image with width and height same as image width and height
Next, Previous, Close Buttons on Popup window
I used below code for uploading image and show in image control with thumpnail metod for reducing image size:
protected void BtnUpload_Click(object sender, EventArgs e)
{
string path = Server.MapPath(".") + "../image/House/product";
string filename = System.IO.Path.GetFileName(fup1.PostedFile.FileName);
string[] validext = { ".jpg", ".png" };
string ext = System.IO.Path.GetExtension(fup1.PostedFile.FileName);
if (Array.IndexOf(validext, ext.ToLower()) < 0)
[Code]...
It save original image in host, now I want it save image that reduce size with GetThumpnail metod in other place How I can do it?
Refer below threads: [URL] ....
I used code for reducing image size(GenerateThumbnail) in above threads my images were in datalist now I have image in my page that isn't in datalist
<asp:Image ID="Image" runat="server" CssClass="GVimg" style="Height:85px; Width:110px" />
And bind it from database
SqlCommand _cmd1 = new SqlCommand("selectFUP1", _cn);
_cmd1.CommandType = CommandType.StoredProcedure;
_cn.Open(); _cmd1.Parameters.AddWithValue("@Behcode", data);
SqlDataReader _dr = _cmd1.ExecuteReader();
while (_dr.Read()) {
image.ImageUrl = "~/image/house/product/" + _dr["Image2"].ToString();
lblerrorV.Text = " ";
}
_cn.Close();
Now I want use GenerateThumbnail code that was in threads for above code... How I can do it?
I have an Image control on my page that should display a thumbnail preview of the actual image. The URL property of this control is assigned through the code-behind using:
imgHolder.URL = @table.Row[0].ItemArray[0].ToString();
Before moving my files to another location, this assignment works fine (The files used to be located inside the application folder). But after moving all files to another drive in the same server, the images don't seem to render any longer. I can upload/download files fine but they just won't display as thumbnails on the page.
This is code that reduce our image size in page
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:Image ID="Image1" runat="server" ImageUrl = "~/Jellyfish.jpg" Height = "400px" Width = "400px"/>
[Code] ....
I want use it in Data List ... In my datalist i have 3 image that i bind from DB i want reduce this image size how i can do it with this code?
I've got:
<asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl='<%# "PropertyDetails.aspx?propertyId=" & Eval("propertyId").tostring %>'><asp:Literal ID="Image1" runat="server" Text='<%# Eval("imageId", "<img src=""images/properties/{0}_thumb") %>' /><asp:Literal ID="Image2" runat="server" Text='<%# Eval("imageFormat", "{0}"" alt="""">") %>' /></asp:hyperlink>
which displays an image from my db.
However, if there is not an image - e.g. if my property record doesn't have any images associated with it, I would like to display a default thumbnail.
After saving image in db how can we retrieve it in gridview like thumbnail size image and by clicking on image in gridview its open as preview. How can we do this in asp.net using c#.

what should i do ?
i am facing a prblem about image resizing.. i know it is a common problem but the scinario is little different here. i have some image in my server image directory and also have their small 128 X 128 sized thumbnail..i show a page with those images like 'facebook photo album' and also linked another page to display them..when a picture is clicked it refferd to that page and that page loads the full sized original image along with picture comments bla bla..., the page width is fixed to 1024px, and the div's width is 800px max which contains the <asp:image..../>; that shows the full sized image. here the problem comes, when a original sized picture is greater that 800px then the remaining part of the picture is croped !! i know it will happen.. that is why i planned to show a thumbnail like pic which's size will be 800px max and link the page with a pop up java script page which will contain the full sized picture only. the problem is i can't resize the picture in a limit of 800px on fly.

[Code]....
However, if the thumbnail cannot be located, a white box with a cross appears instead (as expected).
To handle this better, I would like to display a different image if the thumbnail cannot be located for any reason, for example an image saying "Image Cannot Be Displayed". But I am unsure of how to do this, of even where to do this. Essentially I need to assess the value that the datagrid is using for the particular URL when it is databound. But can I put VB.NET code in this?
