View 2 RepliesJust wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.
View 3 RepliesI have update panel on the page to avoid postback and placed a dropdownlist control within that update panel. DrodownList is filled with Category names and also it's autopostback set to True.
Now whenever dropdownlist index change's on select, untill page loads complete data it should show mesage as "Loading.... in center and middle of the page and background should become bit transparent". And when page load completely with data then that background and message should get disappear.
In gridview [ID] and [ProdName] is BoundField and [ThumbNail] is TemplateField.. I use the code below but the image still doesn't show..
Code:
DataTable oTable = new DataTable("ItemList");
oTable.Columns.Add("ID", System.Type.GetType("System.Int32"));
oTable.Columns.Add("ProdName", System.Type.GetType("System.String"));
oTable.Columns.Add("ThumbNail", System.Type.GetType("System.String"));

View 2 Repliesi have images stored in database and i have to show it in a web page thru datagridview
View 1 RepliesI am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?
is this possible? I only need the width and height, so loading the image into ram would be unnecessary.
View 4 RepliesI had to move an asp.net website from Windows 2003 to another server with Windows 2008. Now when I run the website after setting everything up the images will not load. It is a logo that is in a folder named Images. The file is there along with the folder just like on the other site. Any reason this would not work now? Everything else is working except images. Is there something else I missed in the setup?

View 2 RepliesI need displaying my image file stored from my database into the image control. I've had read some articles and watch video tutorial which there were perfectly working and I followed it but I wasn't able to make it work. The image control just displayed blank. I used Generic Handler to retrieve the image file from my database based on the articles and tutorials I've got. here are my codes below:
Generic Handler:
Code:
<%@ WebHandler Language="C#" Class="ShowImage" %>
using System;
using System.Configuration;
using System.Drawing;
using System.Drawing.Imaging;
[Code] ....
Asp.Net Code for the Image control:
HTML Code:
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "ShowImage.ashx?ID=" + Eval("ID") %>' Height="128px" />
I need to save data in a datatable on a web page where the user is adding items to order. I know how to create a datatable and add data to it. And I will be binding it to a gridview control. But I do not want to loose the data when the page does a postback. Do I need to save it to a session variable for this? Or will the data stay in the datatable?
I found this code posted online. Is this how I would save it to a session variable and then load it anytime?
Code:
Dim dt As New DataTable()
Session("MyDataTable") = dt
' To retrieve it from session
Dim dt As DataTable = DirectCast(Session("MyDataTable"), DataTable)

View 3 RepliesIs it possible to get the size of an image (probably its size in bytes) from a web server, without loading it?Do web servers have accessible properties (fields) with regard to file sizes? This would allow for checking the image size without loading.Often when a web server's directory is loaded into a browser, it tells you each file's size, from server-side. Can I, as an ASP developer, access that data at all?I'm using C# .Net 4Edit: I am acting as a client and requesting this info from other web servers.

Is there any danger in doing that when users upload malicious or affected files or will the code just throw an exception at some point and stop the whole process?
