While writing some web apps with VS2008 there are times I have to do a postback. Such as when I select a certain value in a dropdown, I have to load new data an another dropdown. Well, I was reviewing a web site already written by another company and they did the same method. But when the second dropdown was reloaded with data, the page did not reload. How are they doing this? I owuld love to not have the page reload if possible. All I could think of is they are possibly using javascript maybe to do this?
I created a server control that has some javascript. Everything was working fine until I added it to a page that has localization implemented. The implementation is done within the Global. It sets the Thread.CurrentThread.CurrentCulture and CurrentUICulture based on a setting saved in session. When these values are getting set, the control throws the following error:
Microsoft JScript runtime error: Sys.InvalidOperationException: <file.js> Type has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.
I have the control contained within an update panel on the page, the control also contains an update panel containing all elements withing the control.
I'm having a problem with entering edit mode in Gridview. When I click edit, it shows it in normal mode (labels) even though RowCommand does successfully fire.
But I have to click it AGAIN to get it to show the TextBoxes of 'Edit' mode.
How can I fix this? Is there a way to force a 'postback' on the entire page, or re-render a control? (i'm assuming thats the problem)
Here's the pseudo code:
GridView1_RowCommand(....) If e.CommandArgument = "EDIT" then GridView1.EditIndex = 5 End IF End Function
A click of the 'edit' button returns the gridview with the normal labels. Then when I click it again, the TextBoxes show up.
I have 2 pages..In Both the pages i have one button.If i click Btn in Page one it should transfer the control to Page2 .But if i Click button in Page 2 it should not reload the Page1.It should just display the data in page1 without reloading.
I am using jquery/ajax to grab data from a web service and display them in a div without reloading the page. The problem is that many users want to bookmark or send to someone else their selections to view the same page. At first I thought that changing the URL without changing the page, would be a security risk, however I noticed that Facebook does that in the photo gallery, so it can be done.
I found a method, by changing the window.location.hash, but this apends to the URL the new link after a # and does not change the URL itself. Beyond that, it does not cache the page.
I visited website that it loaded very slow so I press F5 to reload page for many time after 5 or 6 time site show error that you reload page many time and didn't show website I want do it for my site that if users reload page morethan 5 time in short period of time it show error...
I have an ajax toolkit tabcontainer that used to work ok. It has three tabPanels and I can work correctly with the content inside them.
Now I'm trying to add some new tabPanels but I face a problem.
The first time the page is loaded I see all the new tabs. If I make any postback due to any control interaction, the new panels are still visible, but when I move to another page and go back to the page with the tabContainer, I only see my three original tabs.
I have to close the web server (the one coming with visual studio) to be able to see again all my tab panels
I've added a new tabContainer and is the same. The first time I load the page I see everything, but the following times I only see my original three tabPanels inside my first tabContainer (the new tabContainer is not seen at all).
I have a Master page i.e. .aspx and in one of the page which has the main .aspx page is incorpaorated with a .ascx page(User control page). The .ascx page is having a button. so i want to reload the page when i click on this button.Can any one tell me how can i do response.redirect in this secario.
In my code behind, I use MyParam to query a database and bind the result to a gridview that's inside the MyPanel updatepanel. The updatemode of the updatepanel is set to conditional and in the postback part of the code I have MyPanel.Update();
The updatepanel works fine when I'm doing sorting and paging; only the panel is refreshed. However, when I trigger the updatepanel with my javascript, I see the traffic in firebug showing that the entire page is being refreshed.
If I press F5 (IE) after user control was rendered, I get IE's warning window that IE needs to resend the information.... How can I prevent it and why does it happen?
UPDATE:Maybe there is another approach? I want to load specific control (with it's markup) when user selects it from the dropdownlist. if a postback is made the control shouldn't disappear(only if another control was selected from the dropdownlist) Everything is inside update panel!
I have 3 links in my web site master page, every link go to another page. When the client be in any page of it I want to disable its link to prevent reloading the same page on itself and loosing the data which the client enter (Text Box, Radio Button, Combo Box...). How to do this?
Why might gridview only work correctly after reloading the page in IE? And, why does it work correctly on the first page load in Firefox? How might I solve this problem? I thought of trying to instantly reload the page with Javascript if the browser is IE, but this is kind of a bad workaround.

Is there a way where I can actually view the name of a post back element? Below code goves me an alert but all it says is "object HTMLSelectElement". In my case it should be DropDownList3 based upon a "selectedindexchanged" event with autoppostback=true.
Code: var pbControl = null; pbControl = args.get_postBackElement(); alert(pbControl); var ExecutingControl = "DropDownList3" if (ExecutingControl == pbControl) { alert("DropDownList3 - is the post back element");
