I am using GeoMap in my website, and GeoMap is little below in Web Page.I am using filters in GeoMap, i.e., when user selects any station and clicks on "button", all the locations related to selection shows in GeoMap. But everytime when I filter and click on button, page loads and scroll upward then again to see the filteration result in Geo Map, I had to scroll down my page.I want that when I filter any station and click on button, page should stick to that GeoMap section. It should not go upward until user scrolls the page.For this I tried using "Update panel" but then GeoMap javascript is not working.
View 1 RepliesI want to stop postback if a certain value from a ddl is selected.
I've used VB to create a page whereby if a certain value from a ddl is selected then a hidden panel becomes visible. The problem is the likely answer to a majority of my ddl's is 'No' (or a no type response), however, even though the panel visibility remains false upon selecting No a postback still occurrs, the page refreshes and moves back to the top. I suppose this is a question with 2 possible solutions (or 2 questions rather)
1: Is there anyway of setting postback to false if selected value = No? A typical example of how my code appears is below
[Code]....
(i've used the value '1' to represenet Yes)
2: Is there a way of setting the page position after postback? As you can see in my code above i've set the focus on the next control (being a Radio Button) but i mean, is there an actual way of defining where the scroll bar is set?
I have a Gridview inside and UpdatePanel, Rows in this Gridview contains a DropDownsLists, each row has this attribute:

If i click on the dropDownlist Contained by the row, this algo launch a postback, so I can never see this DropDownList deployed.I need a Way to stop this postback. Is teher a solution for this?

firstly i am not really an ASP.Net developer but i do work in C#.
Anyway one of the application that i develop has an ASP.Net section and i need to amend it.
I want to add a Checkbox which when Checked by the User will set a Session variable.
This Session variable will then be accessed on another page where it will include/disclude some SQL and therefore change the behaviour of a Search.
So i have 2 Pages - Page1 that has the Checkbox on it -

I have a JQuery Dialog that is opened when a button is clicked. The first time around, it should do a postback, but when the dialog closes and I click the refresh button of the broswer, it sends the data again and duplicates the data I just entered. Should I add a return false somewhere so it doesn't postback when the dialog is closed. Here is the script:

When I use a RadEditor I want to enable the editor's spell check (working thus far). After a spell check the user can either click on the radmodule (toolbar thing) to either "finish spellcheck" or "cancel." Which is all fine and dandy except the "finish" button causes a postback!! I don't want that at this point!! "cancel" more or less does what I want to happen - I mostly just want a "done" or a way to stop the postback.
I've tried an Update panel but that just grays out the text area after it does the update.
On my form I have a button that pops up a panel to select an option from. It does a postback to fill in a textbox with the selected data. The other controls such as other textboxes and dropdowns are reset. Any way to stop this? Or do I have to save the settings and set it back on the postback?
View 4 RepliesI have a textbox with an autocomplete extender.The user types in a few chars and usually gets a few to a few hundred suggestions back.And its pretty quick.This is on a formview control at the bottom by the paging. It is for a "Go to" feature.But it is returning the suggestions from the same list of search results from the previous page.(It's really the same page but I just toggle the visibility between the GridView Results and the FormView details).And if they select "All Tickets" its possible to get 5000 results from the search.
Now the autocomplete is really doing the same search as the search results did which is like 46 seconds. And then weeding it down further with the prefix (chars they type in the autocomplete textbox).I have a Return to list button. And I want the Button to interrupt, stop, cancel, abort, or somehow just not wait for the WebMethod to finish, and do a PostBack right away.Since btnReturnToList is a normal postback I can't really use PageRequestManager to check if in async or last postbackelementId or anything.
I used popup in my page below is my code:

runat="server" TargetControlID="BtnPopup2">

I am trying something apart of my boundries, is there any way to disable a single intem in dropdownlist or stop the ddl change event for a single item.
View 2 RepliesThis would be a simple one for me if I was binding this dynamically. I don't think it's necessary to have a code behind for only 4 or so values. Anyways here is my ddl.

The problem is that when a user selects a value and it postbacks my ddl resets to the first value. How do I prevent this?
I have 5 dropdpwnlist in asp.net page.. the 5th dropdwpnlist will show data based on 4th dropdownlist. and 4th dropdwpnlist will show data based on 3rd dropdownlist. and 3rd dropdwpnlist will show data based on 2nd dropdownlist. and 2th dropdwpnlist will show data based on 1st dropdownlist... All dropdownlist has auto postback=true.. so it cause postaback each time.. i want to avoid postback coz it refresh all page again and again and shows data.. coz my aplication is in hosting server..
View 5 RepliesI created a dropdwonlist and add colours to the items. But the colours will lose after the postback. After googled, I knew it is because the attributes specified for the dropdownlist were not saved in ViewState and also found the code to Overriding SaveViewState() and LoadViewState(object) from [URL]
But after I copy the code to my web application to create a new class, there are so many error massages. I have spend two days to find the solution, without much success.
