Dynamically Generated Radio Button Calling CheckedChanged Event
Dec 6, 2010
I have a procedure that is generating some radio buttons and assigning a CheckedChanged postback event based on the level being passed through (up to 4 levels). When the first level is checked (radio button selected) the postback event rb_CheckChanged00() is called and a check is done to see if this item has any children, if it does, it will create more radio buttons and assign rb_CheckChanged01 to the CheckChanged event for these - This part is working fine.
The issue I have is when I select the second Radio Button that has been created (the child), it doesn't seem to go to the post back event at all. The page is posting back when I click on it but everything resets because it won't go into rb_CheckChanged01.
I know this info is quite vague but I am hoping someone has an idea on how the post back event works and if I am somehow using it incorrectly.
I have a simple form with 2 radio button grouped. I´m trying to hide/show a DropDown Listbox with the event CheckedChanged, but this event never fires...
Protected Sub AgruparPorCategoriaRadio_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles AgruparPorCategoriaRadio.CheckedChanged AnticipacionList.SelectedIndex = 0 AnticipacionList.Visible = False TemasList.Visible = True ActividadesGrid.DataBind() End Sub
I have dynamically generated a button an its event too.Now want to access a textbox (Generated Dynamically) into the onClick event of the Button.How can i do this?
I have a asp.net page where we need to dynamically generate a table, table row, and a checkbox controls in this row. A button serves Add Row and create checkbox function, which works fine. We have another button which serves on deleting the selected row if a user checks the checkbox. The deleting event is dynamically added to the checkbox. But the delete button is not working at all. I think that the page does not maintain the states of dynamically generated controls, even I set Page enable view state to True. Here is the code:
I am generating a table dynamically with one row having four cells.
First cell is having checkbox and below is the code how i declare it and assign it a new id at runtime.
Now when user clicks on the accept or reject button, there is an error (could not parse server message) however if there is only one instance of both buttons the code works fine.
I am generating a button dynamically at runtime and in event button click I am generating a TextBox dynamically at the runtime.
My question is I should be able to generate TextBox on every click. Suppose say, If I click three times then there should be three textboxes generated.
i am working on a website,As i am new to coding i got a problem in it. It was, i hav dynamically generated link buttons in my page, If i click on the any link button i should get the text of the link button, how to get it ?
I have a GridView control bound to an AccessDataSource. After selecting a row I'm creating a table inside the selected row. I'm adding Buttons to this table. Their Click event never gets fired.I read similar problems' solutions involving recreating the buttons and stuff
asp.net using visual studio 2008 3.5 framework with sqlserver 2008. I have a webform (derived from master page) so its a content form with content placeholder. It has two text boxes, dynamically populated checkboxes from database and 8 radio button groups. It has two custom validators attached with two of my fields also. I've tried every way to clear my form but its not working somehow. I've tried Control iteration method. Ive tried btnReset.Attributes.Add("onClick","document.forms[0].reset();return false;"); thingy...but none is working.
I have 3 radio buttons in a same group. I have onclick javascript event associated with each of the radio button. I want to get which radio button is getting unchecked in the onclick event. How can i achieve this functionality.
I have two pages ,On click on one button I have to redirect the screen to another page.and after clicking on redirect button page will get redirected to old page.
Problem: while coming to old page i have to set one radio button selected amnog two.I have acheived it through session.But the problem,is after coming back once i selected the radio button which is not selected. its not firing the selected index changed event.
Is there a way to respond to the click event generated by any button on a form?
I am trying to carry out a response.redirect( 'button id' & ".aspx"), can it be done?
i.e. If I have a webpage called "button1.aspx" how do I get the button1.click event to trigger the redirect without implicitly coding the click event for the respective button.
<asp:RadioButton GroupName="grpAssoc" ID="rbtEvery" runat="server" Text="Everyone" onclick="return doChangeAssociationType(0);" AutoPostBack="True" oncheckedchanged="rbtEvery_CheckedChanged" /> but oncheckedchanged="rbtEvery_CheckedChanged" not firing even javascript function returns true
I have a GridView, which features a a checkbox on each row (in a template field), where it calls a method upon checked changed (well, when they click submit - no auto post back)
My problem is, the checked change refuses to fire more than once - if I just change the check state of one checkbox in the grid, it works fine. More than one and it only fires the event once.
I've two radio buttons in my web site for selecting sex, one s for Male & another s for Female, Problem is during the Run time, I was able to select both the Radio Buttons, but as per my need i should select only one radio button. And i should perform validation Wn user not selected even one radio button i should show the error msg, like " select sex "
to fire the OnClientClick event of the asp button on the server side (with out clicking the button,it has to fire automatically based on the condition).
I have a DropDownList with the visible property = false. When the user check's the checkbox I want the DropDownList to become visible. If the user unchecked the checkbox I want the DropDownList unvisible again.If there anyne who can help me. I'm using vb. I try this code in the checkedchanged event but didn't work.
Since i have 5 buttons that pretty much run the same code, except for the database updates, i found some examples of how to do this.. so i created 1 button event, and put my general calc code then some if statements to determine what button was clicked.. but doing this now i get a NullReferenceException
and here is the code its complaining about, why would this work within the other button events, but not this one? Ive compared and and all the buttons on the page are the same with the except of the database entries.
When I load the page in the browser and click the CheckBox it becomes checked, the page posts back, and I can see chkTest_CheckedChanged being called.When I then click the CheckBox again it becomes unchecked, the page posts back, however chkTest_CheckedChanged is not called.The process is repeatable, so once the CheckBox is unchecked, checking it will fire the event.I have View State disabled in the Web.Config, enabling View State causes this issue to disappear. What can I do to have reliable event firing while the View State remains disabled?Update:If I set Checked="true" on the server tag the situation becomes reversed with the event firing when un-checking the CheckBox, but not the other way around.Update 2:I've overridden OnLoadComplete in my page and from within there I can confirm that Request.Form["__EVENTTARGET"] is set correctly to the ID of my CheckBox.
Check box's event CheckedChanged is not firing when uncheck the check box :This checkbox will help in checking the checkbox list and whne uncheck it will uncheck the checkbox list.I am using AJAX for this page post backs.Here is the html code for check box:
I am using a list view inside that in item template i am using a label and a checkbox.I want that whenever user clicks on the check box the value should be updated in a table.i am using a datakeys in listview.on the basis of datakey value should be updated in the table. Query is:string updateQuery = "UPDATE [TABLE] SET [COLUMN] = " + Convert.ToInt32(chk.Checked) + " WHERE PK_ID =" + dataKey + " ";` also i want some help in displaying the result as it is inside the table.means if the value for column in table for a particular pkid is 1 then the checkbox shoul be checked.Here is the code snippet:
