An ASP.NET Chart control is refreshed on page post back -- but I don't want it to be.
In my aspx, I have:
[code]....
The problem is that on a postback from some other control (Telerik RadGrid) the chart series contents disappear.
How can I secure the control from being destroyed in the postback?
I am developing a simple rating system for my employer's profile based web-app. Here is my problem:
The actual page is domain.com/review.aspx?user=username, but I use the url-rewrite module in IIS to use domain.com/username/review The page contains a repeater control that displays reviews for that username, as well as a form for people to create new reviewsWhen the form is submitted, asp.net re-appends the (hidden) querystring to the url on postback.The post-back url is now domian.com/username/review?user=username&review, causing the page to break if refreshed.
Is there any way to keep asp.net from re-appending the querystrings that are actually already present, but re-written with IIS
Live link <- submit a review, and then refresh the page (edit) by clicking in the address bar! Beautiful yellow error message.
EDIT
C# code:
protected void submitReview(object sender, EventArgs e)
{
try
{
int starRating = txtStarRating.Text == "" ? 0 : Int32.Parse(txtStarRating.Text);
testimonials.addNew(Int32.Parse(txtHiddenUid.Text), reviewContent.Text, reviewerName.Text, true, starRating);
[Code]....
Some say it is not a bug it is default in asp.net. but for me it is a bug in logic. When you say refresh it should be reload the component that you are refreshing. But in asp.net i notice that they recalling all activity and viewstate like event and data that are triggered in the previous postback. My opinion it is a redo not refresh. this is only my observation on the issue dont hate me on this microsoft fan.
on aspx page:
private
static string __VIEWSTATE_FETCH;
protected void Page_Load(object sender,
EventArgs e){

View 5 RepliesBeing new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I've a grid view which could have huge data. When any control like a button causes the postback, I do not want gridview data to post back as it is not required and results in slower responses.

View 6 RepliesI have a special requirement with regards to popping up a MsgBox in ASP.Net. There seems to be various solutions across the Internet using the Javascript confirm box, and passes the response to a hidden control, from which VB.Net can the read and further respond ...but the Javascript code is initialted by a button on the ASP.Net Form. I want to be able to pop-up a MsgBox in the middle of my VB code-behind using the Javascript trick, which passes the result to the hidden control, which can then be read by VB.Net .... the problem is that the page has not refreshed and the hidden control still contains the value from the previous Submit .... I'll attach my code. If anyone can come up with a solution, will you have achieved the impossible!

View 4 RepliesI have a page that I am adding user controls to the bottom of the controls each postback. The User Control has a textbox in it and the focus needs to be on this newly created control textbox each time. It all works almost perfectly however when there are too many controls to fit on the page, because I set the focus to the textbox the bottom of the page is set to the textbox that has focus not the very bottom of the page. I have a submit button below this which ends up below the page limit. How can I set focus to a textbox but still scroll to the every bottom of the page to show the submit button.

View 2 RepliesI have an aspx page that postsback when it should not. there are two text boxes, two listboxes and two buttons on the page. if at any-point the enter key is pressed the first button is given focus and "clicked" resulting in a loss of selection within the listboxes.
How do I disable this? there are tons of tutorials on how to capture the enter button and execute a method but I could find one on how to simply disable the neat "let me grab the first button I find and click it" feature mentioned above.
I searched google and found asynchronise post back trigger is used if we want update panel to post back on some event of control if it is out side the update panel. Than what is purpose of post back trigger ?
View 2 RepliesI am trying to translate a chart from a classic asp componant to a 3.5 chart control. I have two problems so far:
1) (hopefully easy) For the XAxis and YAxis titles (not labels), how do you make these titles bold?
2) (seems impossible with .net) How can I break up the background color so that certain parts of the background are different colors? In the legacy control, the original programmer could drill down control to the y-axis lines for coloring the background.
Example in a Y-axis with lines from 0-100 with 10 intervals:
a) 0-50: the background color would be BLUE
b) 50-80: the background would be GRAY
c) 80-100: the backgound color would be RED
As far as I can see, with the .net chart control, you can only have a single color or a single gradient of two colors, but not striped as I am trying to describe above. It seems that if an old classic asp componant has this striping functionality, the .net control has got to have it somehow.
I'm working with asp.net 3.5 c#
I've seen a good few questions like this around but havnt actually come across any articles with the answer (maybe just been unlucky with my research!).
Basically I'm looking to have say 3 links (or buttons) on a page, which in turn will dynamically load a specific user control into an update panel with AJAX.
Then I would like the usercontrol loaded to be capable of handling postback within the update panel (basically no page refreshes) to do its processing and return output.
Does anyone have any pointers to articles/blogs covering this?
I've seen many but non covered handling postbacks from the user control or handling the postbacks within the update panel.
I have a custom server control (composite control having dynamically created dropdown boxes and textboxes). I have enabled AJAX in order to avoid page reload.The server control is used inside the ASP.NET webcontrol having few buttons which controls the visibility of the server control. Now I enter values in the dropdown box and texboxes and click on any other button. After this postback the last entered values are gone! The control is not remembering the values. How can I retain the values after post back?

View 7 RepliesI am writting an application that displays 3 visable text boxes and 1 hidden text box and one hidden button.
My application sets focus to the hidden text box.
The input comes from a barcode scanning gun which gives the "enter" command after the scan is complete...this essentially clicks the hidden submit button which moves the text from the hidden text box to the currently active visable text box.
To start the application does some verification on what was scanned then gives the user feedback on what was scanned then enters it into SQL.
My problem comes with the last scan...the page does not actually post back to give the user the neccessary confirmation before commiting the info to SQL and resetting the form.
Is there a way to either do somethig after the page has been rendered or do an additional post back somehow before calling the commit and reset functions?
