I am facing problem with the dynalically generating the image at particular with coordinate points on image map through code behind (aspx.cs). As per my requirement i need to generate Hotspots dynamically and also displaying an image to indicate the Hot spots.
View 2 RepliesI am unable to figure out the best way of handling the following scenario. So far I have just been messing around with the code trying to get all these pieces to fit together.
I have a multiform view, and within one of those views I want an image to be displayed that is created on the fly based on data from a database, though I have hard coded the values to at the moment, I'll add the database piece later.
I load two images as bitmap objects, add the smaller image onto the larger image, then write the new image to a file as a jpeg. I then load the jpeg into the view controller
[Code]....
First question, I really do not want to create a temporary file. I have tried several different pieces of code to convert the bitmap object into an image I can load into the web controller, but have failed.
Second, I need to set a hotspot in the image that is being displayed in the multiview View2, and I am not able to do so. Is there an easy way of doing this, or should I call the above code as part of an ImageMap, where I can easily set the hotspot? If so, how?
I realize this is kind of a convoluted post, but I am at a cross roads and not sure which direction to go.
I've googled this to death and can't find anything that points me in the right direction. I want to generate a report that consists of X no. of gridviews (X can vary) where each gridview is added one at a time using ajax (to avoid timeout of rendering all gridviews in single post back). I am also hoping that when rendering the next gridview a progress bar/timer can also appear in it's place until it's finished processing and is rendered.
Does anyone know how I might tackle this? I wouldn't have a problem doing this in a single post back but now the reports are timing out I need to generate the report piece by piece dynamically.
I have a xml file which is currently made manually and I have to make a functionality(UI) where user can enter the data and I have to store the data and generate the xml file dynamically in .NET.
Problem is the format of the xml file. I am not able to decide how I am going to store that data and then dynamically generate xml from that.
find the some of the extract of the code from the xml file below:
<?xml version="1.0" encoding="UTF-8"?>
<DATA>
<SDACTS>
<SDACT TYPE="Economy" COLOUR="0xff0000"/>
<SDACT TYPE="Environment" COLOUR="0x00ff00"/>
[Code]....
I am planning to generate the UI from database.The platfrom will be ASP.net.Can anyone help in identifying the best design pattern/Architecture that suits for generating the UI and events dynamically.

I am trying to add some filters to a gridview that I am working on, and I'm wondering if it is possible to generate links or buttons above the gridview based on the years returned in the dataset. For example, if my dataset contains dates from 2001, 2009, and 2031 in my date column, I would like to be able to take that data from my SQL query (getting a distinct list of years is not an issue), and generate the buttons. From there, I would filter the data in the gridview based on the user clicking the buttons.
Is dynamic generation of buttons possible in ASP.NET? I do have some other ideas of how to accomplish the same functionality, but I would prefer to do it this way.
my problem is i want to generate gropu of texboxes by clicking add button(one row of textboxes).in my application i want to generate one complaint id.one customer may give two or more complaints at a time.suppose,he give two or more pnr numbers and their status andprioirty may differs.for this complaint i need to generate one common complaint id.how it is possible..?
View 7 RepliesI am generating Textboxes dynamically on selection of treeview node.
The problem is i have a button and on click of it postback happens and all the date entered in the textboxes and textbox it self is lost ;(
My application I am using pagination.Using pagination i bind the records with listview control.
I generate the buttons dynamically according to the number of pages which is calculated from number of records returned from dataSource.when i click on a dynamically generated button its corresponding event handlers methods should get evaluated.Since asp.net page is stateless I can't keep the state of that dynamic controls after any postback.
Just Now I have seen the Article "How to get the Id of Control that cause postback in asp.net?". I got some idea from that article. Any example for "Creating link buttons dynamically and handling its corresponding event handler in Asp.Net".
In javascript I have an image which I set the .src at runtime in javascript. The .src points to a asp.net page with a few values as querystring parameteres that I want t capture on the server. this page has empty content. In code behind in the page load I need to generate the smallest image possible and return it as the response. how do I generate a small image and return it in the response?
View 3 RepliesI have a small form with some static elements that I am able to access with javascript the bring up a popup. 4 textboxes are generated and attached to a updatepanel. I've been trying various methods of validating the contols without generating postback.
I found anytime i registered a javascript to the scriptmanager the page must refresh.
Is there anyway it can be done?
I am dynamically generating script code to return transaction data to Google Analytics using their ecommerce script. The code that generates the script is fully tested and functional on my development machine and when I view the page code the script, along with any values that were passed to it, can be seen above the </form> tag. Happy days, or so I thought. For some reason the code is not being generated when I test it in a live, hosted environment. I cant figure out why this is the case as the code is quite simple. I simply generate the script code and register it on the client side (see code below)
//Capture the transaction data for analytics ecommerce tracking
//Generate the necessary script code
string strAnalyticsEcommerceScript = Analytics_Ecommerce_Script_Creator();
//Register the script on the page
Page.ClientScript.RegisterStartupScript(this.GetType(), "AnalyticsScript", strAnalyticsEcommerceScript);
The page in question is called "Order-Successfull" and is where customers are sent to when they have succesfully payed for an order. On this page:
-The order is added to the orders database table
- The customer is emailed an order confirmation email
- The google analytics script is generated and registered
The Sequence is as follows:
[Code]....
Whats really interesting is that if I move the Analytics script creator code before the code that sends the emails, the script is generated and can be seen when I view the page code. If I do this, however, the emails do not get sent. If I lay the code out as per the code I have inserted in this post, the emails get sent but the script code is not placed on the page.. The code to that actually sends the emails is quite standard:

For the SaveImage, I want to be able to set my image name with its own name.
the name can be found using:
string fileName = Request.PhysicalApplicationPath + @"graphs"+User.Identity.Name+graphID+".jpg";
Right now, when I click save, it always show chart.png
And also, I want to download the chart as jpg.
I am using a treeview control and just want to add nodes dynamically. On selecting a node the results based on that node must be shown below.
View 1 RepliesIn my Admin page, I have a drop down list containing all current user tables in the database. The user chooses one.
My DetailsView below uses that parameter to populate itself with data from that table. The stored procedure used to select the data passes a string to sp_executesql. The string is concatenated from a select statement and the tablename parameter. Can I do something similar for Update/Delete statements? I'm not sure of the best approach, given that I won't know which/how many fields will be in the DetailsView at runtime, and which of these are keys - the choice of table depends on the user. I think Insert will be straightforward - am I right? I would like to streamline things as far as possible. Is it possible to dynamically pass in the values in, say, a string, and get my stored procedure to understand them? And what's the best method of grabbing the values from the DetailsView in this situation?
Here is this thing which to me looks possible, but when I searched over the net I couldnt find anything.
I want to create a page where I can upload an image using any upload function and then display it. Now after diplaying it I want to select the hotspots for an image map. The coordinates of image map values are stored in a database.
Basically I want that to create image maps and hotspots I dont use any offline software, this work is successfully completed and working perfectly, but i want generate one identification where i click the hot spots position in image or CSS file Generate for user identifications, So how can i solve this problem.
I hope You are clear in that what I am looking for.
I have a grid control that is dynamically generated according to supplier. If I have 2 suppliers I have 2 grid controls.
I need to send email to client the product information along with how much grid is generated.
Th email body is hardcoded along with required parameters. Something like,
"<table style='border:1px #6C9EE1 solid;' width='100%' border='0' cellspacing='0' cellpadding='5'>"
+"<tr><td bgcolor='#6C9EE1'>" +"<span style='font-size: 14px; color: #FFFFFF;

How do I add dynamic controls to such code? Also I need to change mail body as per certain conditions.
What I'm trying to do is take an instance of a control, and figure out what the markup would look like based on the property values set in the code behind. We've built a web-based web form designer. At the end of the design process we save the markup. For simple controls with supported types, generating the markup was easy. For complex controls with nested properties or unsupported types, we're faced with creating a custom markup generator for each custom control. I was hoping to find info out there that would jump start this development effort.
In simple terms, I have this:
Dim Ctl as Control = CType(Asm.CreateInstance("MyNameSpace.MyControl"), Control)
Ctl.Name = "Name of my control"
And I want to end up with this:
<cc1:MyControl ID="MyControl1" runat="server" Name="Name of my control" />

I try to establish a dynamic HTML table with data for an item. i am getting trouble showing the image for the item, i am getting my data from the database, i have saved my image as image in the database, and i used byte[].
I have the following code for desplaying data:
protected void DDLitem_SelectedIndexChanged(object sender, EventArgs e)
{
var item = new ItemControl(); // this is in the BLL layer.
List<Goods> get = item.returnGoods(DDLGoods.SelectedItem.Text); // DDLGoods is a DropDownList. and the method returns a List<Goods>
var out = new StringBuilder();
out.Append("<table><tr><td>Name:</td><td>Designation:</td><td>Price:</td><td>Item Number:</td>");
foreach (var v in get)
{
out.Append("<tr><td>" + v.name + "</td><td>" + v.designation + "</td><td>" + v.price + "</td><td>" + v.itimId + "</td><td></tr>");

I have a Folder which consists of number of images. Initially have to load the first image from that folder in a page. when user click the first image it should display the second image where it will have next link for the third image. when the user click the next link now then it should display third image where it will have next link for fourth image and previous link for third image where it should repeat upto the end of the image.
Can any one tell me how can i display images one by one by passing query string value to the images and how to change the link dynamically for the images
Update:
Intially i want to load the first file without passing query string, with the first file there should have next file link. Once the next link button is clicked then only have to pass the query string.
how to pass the query string from second file to end of the file,
DirectoryInfo oImageFolderInfo = new DirectoryInfo(this.ImagePath);
FileInfo[] oFileList = oImageFolderInfo.GetFiles("*.*");
string fileName=string.Empty;
if (Request.QueryString["filename"] != null)
