Oncheckedchanged() Event Is Not Happening When Deselect The Radiobutton?
Dec 21, 2010
In form I have added two radio button and on one radio button oncheckedchanged event has been registered but this event does happen only when i select the button and not when i select the other(The checked is changed).
I have to create columns dynamically based on a datatable, some field type info and some header texts.
I do that by creating templates.
It created the grid fine and all looks good, however when i click a checkbox and the checkedchanged event fires then something odd happens
The first time i click its fine and i get the expected values in the event
But the second time then the event gets fired with the values from the first time and then again with the values from the checkbox that i actually clicked.. The third time the event gets fired 3 times, first 2 times with the old values and the third with the correct value.
Here is the code:
using System; using System.Collections; using System.Configuration; using System.Data; using System.Linq; using System.Text.RegularExpressions; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq;........
Here is my situation: I have a overview of subscriptions that look simple:
Active (bool), ID (int), StartDate (datetime) and MaxUsers (int).
I've put this in a Gridview and it renders nicely.
Now everything is simply in ItemTemplates and are formatted.
Now a new feature: In the Gridview active should be a checkbox and when clicked on it, it should (de)activate the subscription. Or simply said, Active status is updated. Now me being a simpleton thinks:
[Code]....
and the cs:
[Code]....
But! the event doesnt get fired. Now I've searched with google and also through this forum and every time I get the answer: autopostback on true or use commandname. Now for this little feature I think the commandname use in combi with rowbound is overkill for such a little thing.
Now I hope I'm just missing something because this would be really nasty and stupid to make it so complicated. I like the autopostback and oncheckchanged combination because it logical, but why doesnt it work?
I have an issue that seems to only happen on my production server. I show or hide table rows whenever the buttons are clicked. However, when I do a postback on the checkbox, all of the rows become visible and the textbox stays empty. It works correctly on my test server and local workstation, just not in production.
Here is the markup...
[Code]....
Here is the code behind...
[Code]....
Here are the unexpected results whenever I check the chkShow2 checkbox... I am guessing this is a configuration issue on the server.
I am selecting multiple dates on a calendar control ,, and then i insert them into DB. The problem happens after i insert, if i want to add new list of dates, once i start selecting on calendar all last selected dates appear (get selected on calendar) Does this mean these dates are saved in Session or what? Here is the code I am using:
I have a button, contained in a panel, with a click event, that works fine. However when a users presses another button, I need to move this button into another panel (this is actually a panel with a modalpopupextender), so I this code to do so:
newPanel.Controls.Add(buttonPanel)
It all get's moved and looks fine. However now when the button is clicked it doesn't fire the associated event. I have tried re-adding the event in the page_init, with this code
((Button)this.FindControl("serverModalSave")).Command += new CommandEventHandler(modalSave_Click);
But with no luck. How can I get this button to fire it's click event when moved, and why does it stop working when it's moved?
EDIT:
This Button needs to be added to a panel specified by the user at run time, so there is not a way to determine where the button will go in advance.
I could instead of moving this button, create a new one, but because this button is not created in the page_init I am having issues getting that to fire an event either.
I was wondering if anyone had an easy way to wire up javascript event handlers to events happening on the server-side. I have a long running process that includes a lot of steps, and would like the client to be continually updated with new information as the steps transition. Will this involve some sort of polling mechanism?
I have a gridview with rows of data and a group of radio buttons for each row that can be selected. But when selected the event never fires for the radio dropdown.... why?
I'm dynamically generating radio buttons in my code behind and assigning javascript to them as they are created. This javascript will change the value in a hidden field for when a postback is eventually triggered (autopostback on the buttons is disabled). I am using the exact same method with ASP ImageButtons and it works fine but when I do it with the radio buttons the event never triggers the Javascript. I suspect that I may be using the wrong event name but I have tried several (onclick, onCheckedChanged, etc).
Here is a sample of the VB.NETcode - how come this works fine with my button but not my radiobutton!
//This is my hidden field ClientScript.RegisterHiddenField(Me.UniqueID & "_someVariable", "") Dim radDefault As RadioButton = New RadioButton() radDefault.GroupName = "radio buttons" radDefault.AutoPostBack = False //This adds the Javascript to set the hidden field with an onClick event radDefault.Attributes.Add("onClick", "document.forms[0]." & Me.UniqueID & "_someVariable.value='0';document.forms[0].submit();")
The code is simplified as the button generation is actually through an iterator but the same properties are given to each generated radio button.
I have a gridview where i have a radio button. What i need is to on the selection of the radiobutton i have to find the datakey of the gridview. Also one more issue with that is , i can select more than one radio button, which should not happen.
ASP.net radiobutton change event writes the new selection to an XML file and that needs to be shown on the page but does not show the changes on the page since the page load occur before the event fires. give some insight how to resolve this.
In my Code Behind in test method I am trying to set the checked to true, but in the ApplicantFormBound event when i debug it is never true...any reasons why? Basically I want to set the Validator to true when checked.
I am selecting multiple dates from a calendar control, asp.net. I want the user to be able to deselect a date if he/she click on the date a second time ,, is it possible ,, how can i do that?
I am using a gridview where there are 6 cols and the last col consist of checkboxes. I wrote a code such that all the checkboxes in the col are selected or deselected at once by clicking the header checkbox. Now the issue is since I am using paging for the Gridview, once I select the checkboxes in the last col and go for the next page and come back to the previous page the checkboxes are deselected. I want to keep the checkboxes selected even after pagination.
I have a asp:ListBox wrapped inside an asp:UpdatePanel. The list box contains Bus Codes. If I select AH, for example, and then scroll down to select XY, the listbox jumps back up to the top of the list instead of staying on XY. Listbox's autopost back is set to True. As I need to get selected values and then pass it to another web page to display a crystal report. The report web page is opened using JavaScript Window.Open and on page load of the web page that contains the listbox this JavaScript is added to a button. Is there a way I can stop my list box jumping back to the 1st item?
I m passing Id from one page to another other page using querystring string. At first time it is displaying data in datalist in 2nd page on basis of selected Id. But again on home page while clicking on other image then previous record is showing. At second time, page load is not happening while testing using break point.
What is the error.? There is also AutoEventWireup="true".
NOTE: I have an aspx ASPX page which is rendered from a SiteMap. 1st time the POSTBACK happens, but subsequently in same sessions, POSTBACK does not get fired.
HACK (not working) - I have the refresh meta tag like this inside the HTML tag
When I am visiting this ASPX page, I want this META tag to be called only ONCE. So, I was trying the following code in OnLoadComplete event ?- HtmlMeta meta = new HtmlMeta(); HtmlHead head = (HtmlHead)Page.Header; head.Controls.RemoveAt(0);
We're getting a confusing error on two of our pages in our ASP.NET application. Both pages originaly had tags to reload the page every so often if a user sat on it for a while, but opted to remove those in favor of some AJAX flavoring. Specifically, we created timer controls on the page and wired the timer's tick event as a trigger for an update panel to reload a portion of the page. The page(s) also have scriptmanagers on them as we don't have one on the master page. This largely works great except we're getting a lot of these errors:
"The page is performing an async postback but the ScriptManager.SupportsPartialRendering property is set to false."
It is my understanding that if the .NET framework detects a browser doesn't support partial rendering it will set the ScriptManager.SupportsPartialRendering value to false and we're NOT overriding this in any fashion. Therefore, the pages shouldn't be by performing async postbacks if that value is false, but based on the error the postbacks are still happening and the page is throwing an exception.
Curiously, the user agent always seems to be GoogleBot or "Mozilla/4.0 (Windows 98; US) Opera 10.00 [en]".
We are creating a new user control using a boiler plate template for our application. We noticed that anytime a textbox on the new user control has a focus and the enter key is pressed, the form executes a postback. This happens even if the AutoPostback on the text box is set to true. No other user controls in our app behave this way. What could be some of the places for me too look?
