Web Forms :: Checkbox In Gridview Doesn't Fire OnCheckedChanged Event
Oct 26, 2010
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'm implenting a functionality of inbox where i have a GridView and code as follows:
[code]....
But here even if i select a checkbox onclick event gets fired. i dont want the checkbox to fire this event. It should just act for selection of rows. What shall I do?
i have two nested gridview inside an update panel. there is a button called btnPhoneEdit inside the child grid view. when the button gets clicked, it do cause partial post back as expected but it fails to invoke btnPhoneEdit_Click.
here is how my grid view looks like and how i add my custom data source to both parent and child grid view. [Code]....
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.
A little confused on something. I have a User Control in a master page. In the User Control there are image buttons. when I try to wire any click event even to say update a label in the User Control itself, nothing gets updated.
It is as if the postback is not handled at all.
What I want to do is click the image button in the User Control and then change a value in the master page. This could happen a few ways but for example it could update a public property or a control itself like a textbox or label.
I in page load i change the checkstate of checkbox false to true or true to false, in turn which i expect to fire the check_change state but seems not firing the event
protected void Page_Load(object sender, EventArgs e) { chkDegisim.Checked = true; chkDegisim.Checked = false; } protected void chkDegisim_CheckedChanged(object sender, EventArgs e) { int a = 1; } when i put a breakpoint to chkDegisim_CheckedChanged, it does not fall into the event chkDegisim_CheckedChanged. chkDegisim's autopostback is true and i have declered chkDegisim_CheckedChanged event in aspx.
why it does not fire chkDegisim_CheckedChanged event?
I've run into a problem with one of my web sites and I am having trouble figuring out the problem and a good solution. This is my scenario: I have a user control that displays a slideshow with images and some text that changes every fifteen seconds. To do this, I have an update panel that contains a timer control with an interval of 15000. It calls a method called slideshowTimer_Tick in the codebehind. The web page that contains this user control is a relatively simple page; no update panels or timers, just divs.
The problem I have is that if I have two of these user controls on the page, the tick event only fires for the first control. It never fires for the second control, although the control is full initialized otherwise.
I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).
we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.
I have a problem with an asp.net project.I have a default.aspx page with a webusercontrol ascx inside.I have one combobox in my default.aspx and another combobox inside usercontrol.If I fire up my simple application, I noticed that when I select an item in one of the comboboxes, the selectionindexchaged event doesn't fire and le dropdown doesn't close.I have AutoPostBack="True" an all combo.
I have a datalist that loops thru cart items. Within the datalist template I call a user control that has a small form that gets repeated for each item. When this control is called outside of the datalist, the form submits fine, but when called within the datalist the button has no event action. I've tried adding an event handler to ItemDataBound of the datalist, but still no event action. How can I get my form to submit?
I am fairly new to the asp.net and experimenting with it to learn the page life cycle. Here is a problem that I have been unable to resolve for past few days.I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data.
Here's an odd one that I've never seen before. Only on IIS, not in Cassini but in all web browsers I have a button that posts back and the page_load event fires, but the actual button click event doesn't fire. there is no re-writing of the page or anything else happening.
I have a gridview with a onrowdeleting="SellersGridView_RowsDeleting" switch. My method is:
[Code]....
Well, it seems that when I try to delete anything - nothing happens. I tried to change the first line to Response.Redirect("foo") just to check if the event itself is fired, and it turns out that it doesn't.
i have a JQuery ui dialog box that opens up as a contact form when a link is clicked, which works fine, my problem is trying to submit the information.
When you click the send button it fires a button click event of another asp:button ive got hidden on the page...
the post back event fires and the page reloads but the asp:button click event doesn't not fire?
I add linkbutton controls dynamically to a panel, this works fine, but I also add eventhandlers to them like this.. AddHandler mLink.Click, AddressOf mLink_OnClick But when I click the linkbutton links, the event never happend. I have one updatepanel wrapped around some panels. What could be wrong?
I have a multi view with 2 view in my page. when page is loading first view is set active. by click on a click I set active second view that contain AsyncFileUpload1. but UploadedComplete event doesn't fire. This control works outside of view correctly but into view doesn't work. I have to use multi view and this 2 view in my web page. what can I do?
