I have a web page rendering two pie charts using the ASP.NET 3.5 chart controls. On my dev server (IIS 5.1) the charts load well. On the QA server, the charts load pretty slowly and sometimes one or both of them doesn't even load. I am loading the charts using the codebehind tag. Is there anything else that could be done to make these charts run faster? Note: I was previously using dotNETCHARTING and never had any issues with it. Nothing else has changed except for the charting engine.
View 1 RepliesI have a custom web part that I am trying to call the RenderContents method on, but the results only contains the surrounding div for the web part, and not any child controls.
Take for example this simple web part:
namespace MyWebParts
{
public class MyTestWebPart : WebPart
{
public MyTestWebPart()
{
this.CssClass = "myTestWebPart";
}
protected override void CreateChildControls()
{
base.CreateChildControls();
this.Controls.Add(new LiteralControl("Nothing here yet."));
}
}
}
Then, in an http handler, I'm trying to instantiate this web part and call its RenderControl method. The result is <div class="myTestWebPart"></div>.
Does anyone know why I am not getting my controls from CreateChildControls also added to the output?
I have tried searching for the answer but have failed to get any insight into this problem. Look at the following two examples. [URL] (JQuery modal dialog without <input> element) Above pages have very simple JQuery modal dialog, whihc displays correctly in IE, Chrome, Safari and Opera. Unfortunately, Firefox does not display the modal dialog with <input> correctly. It displays the other one correctly. I have tried the following without resolution to this peculiar problem:
- Changed doctype
- Used <table> to enclose <input>
- Used <div> to enclose <input>
- Used all possible CSS display attributes for <input>
I have menu item on my master page that has block around the text when the page is first run. I wrote in the css on the link and visited property to change the color to match the image color that it is on. When a menu item is clicked the color changes to the right color. How do I get it to the right color on when the page first opens or is there a way to get rid of the block or make it transperant?
View 1 RepliesYou're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="~/default.aspx" title="Home" description="">
<siteMapNode url="~/1.aspx" title="Link 1" description="" />
<siteMapNode url="~/2.aspx" title="Link 2" description="" />
<siteMapNode url="~/3.aspx" title="Link 3" description="" />

I'm developing a Asp.net server control (inherited from DataBoundControl) and I have just one button inside it for now which is created in CreateChildControls override. Even though this button have Click event assigned in rendered page the button don't have onclick event with __doPostback or something similar. Am I missing something?

I have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.
So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place?

<%for (int i = 0; i < 30; i++)

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?
In my project when i click any button or linkbutton, it doesnt fire any event or doesnt postback.

View 1 RepliesI'm new to ASP.net 3.5 and creating a test web site. I have created a master page for my web site with page content blocks. Now I want to use some javascript on the client side to provide for more interaction. I would normally create page specific Javascript functions and insert them in a <script block on the page. Howevere the Javascript script block must be placed before the <HTLM block. If I'm using Master Pages, it doesn't seem that I can use page specific Javascript functions. How can I resolve this problem? I think my options are
1) Don't use Javascript. Use ? instead to write client-side code.
2) Don't use Master Pages because you cannot use Page Specific Javascript functions.
3) Here's how to insert Javascript Functions in a Page with a Master Page.
I have a table in a div which starts as invisible and by clicking a link it should be shown. The tables are in my aspx files while the div(s) are in the masterPage. This works just fine in FF but most of the time they do not show up in IE. If I manuallydo a refresh first then most of the time the div is shown.
<div id="drag" style="z-index: 5" >
<div>
<div>
script language="javascript" type="text/javascript">
var theSubject = '<%=Session["subject"]%>';

When to write try catch block?
Should I write it for each method or only in event handlers or ????
What happens when an exception occurrs? What is the stack for exception?
If I use it at entry point (event handlers) then how do I get actually at which line error occurred?
Suppose an exception was thrown from Data Access Layer How do I get it in presentation layer that exactly in which class method at which line why that error occurred?
Is it true that excessive use of try catch makes application slow?
Can somebody show me a better approach of looping through a Try -Catch statement. I have something like this:
Try
dbConn.Open()
Catch ex As Exception
errmsg = ex.Message
End Try
I need to try to connect 5 times before logging an error. My first thought was to nest Try - Catch 5 levels but I didn't like that idea. I'm sure there is better solution to it.
When add elements, like text or other controls inside a big <div> block, they are alwasy on the top.
Ex. <div style="height:50px;">this is a test</div>
Does anyone know how to use CSS to position them in the middle of it? I tried using CSS vertical-align, no luck.
Is there a way to disable input into a textbox at the same time allow cursor focus?
View 3 RepliesSince everyone yells at me that MessageBox doesn't work when the project is uploaded to the server, I need to migrate to javascript alert box. As I was changing my MessageBoxes, I tested and found that they weren't being produced. I'm not sure if it matters, but they are in a try/catch block, which is shown here:[Code]....
This all worked before when I had MessageBox - it showed, then the page redirected when I clicked Ok.
I either don't understand how try/catch works, the javascript isn't adding, or Response.Redirect is executed before I can see the alert box and click Ok on it.
(just as a note, everything works fine, but the alert box doesn't show)........if I add the (javascript) code before the try block, the alert box comes up, so it's not something wrong with the writing of the javascript or executing it at least (I think).
How do I setup a fix length to block an arrow image 'GIF' from wrapping around the search field as the page gets smaller?

I'm kinda new to vb.net web forms and I'm trying to figure out the best way to create a dynamic employment history block on a web form. You know, the block where you list who you worked for, salary, dates etc.
On the form now I have three employment history blocks inside a table. If the person filling out the form has more employment history, I'd like to have a "add history" button that when clicked adds another employment block to the table. The user can click it as many times as they want to add more employment history blocks. I'd rather not reinvent the wheel here, so if someone has a sample of this and would be willing to share, or can point me to vb.net sample on the web that does this, I would appreciate it much.

View 1 RepliesI'm reading an invoice dataset and building a html table with checkboxes and textboxes in it, and I put that code in a postback = false block, then i got a button and a literal. The button click will loop through the html table checkboxes to calculate a total and assign it to the literal and display it. I got everything working except one thing, every time i click the button, the html table refreshes and lost all the value in textboxes....even though I put the html building block in the postback = false block,it seems like it still won't preserve the values in the textboxes once there's a button click...Anybody knows a solution to that? I want the textboxes keep what values are there.
Here is the code part:
