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.
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 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.
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:
I have a checkbox, textbox and requiredfieldvalidator inside the updatepanel. Once user checks selects checkbox I am enabling requiredfieldvalidator.
I have one more textbox, requiredfieldvalidator, validationgroup and Linkbutton outside updatepanel.
Strange thing is Checkbox checked event not firing in some cases,
1. Check the checkbox (which enables requiredfieldvalidator) 2. Click the Linkbutton (fires two validators) 3. Uncheck the checkbox (which should disable requiredfieldvalidator) 4. Click the linkbutton again (again it fires two validator, which should fire only one validator)
Note: The problem only arising when I add javascript block to linkbutton in page load event.
1. chkresponse = new System.Web.UI.WebControls.CheckBox[cnumber + 1]; for (int i = 0; i < cnumber + 1; i++){ chkresponse[i] = new System.Web.UI.WebControls.CheckBox(); chkresponse[i].CheckedChanged += new EventHandler(chkresponse_CheckedChanged); chkresponse[i].AutoPostBack =true; }
2. thereafter adding them to a panel
Panel1.Controls.Add(chkresponse[n]);
3. then added the checkedchanged event:
public void chkresponse_CheckedChanged(Object sender, System.EventArgs e) {Label1.Text = "response";}
but the event is never fired. the panel is insdie an updatepanel.
I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event. The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
I am using Repeater and i have checkbox in every row. I have to post all the rows to a DB Table.
The problem is:When i uncheck a row and then press the save button , all the rows are getting saved.
I checked with debugger that actually i see the checkboxes unchecked , but the debugger shows them checked.
Checkboxes have JAvascript onclick events associated with them.
[Code]....
My javascript function updates the labels on the page.My getvalues from repeater code is as follows. i am checking all the rows whether checked or unchecked. [Code]....
why checkboxes are showing always true whereas they should have been false (as they are unchecked).
I have below code, where I have a ListView that shows following columns ID, Category name and Visibility
The problem is the visibility, which is a checkbox. When I click the Edit button the checkbox the CheckBox cell suddenly shows a string saying "true" (That is if when the checkbox was checked before entering the editing mode) and the checkbox shows up unchecked.
What I want is to remove the "True" string and instead let the checkbox be checked, (if it was checked before entering the Editing mode).
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'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 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 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 have a web form with two RadioButtons, both use the same GroupName, both have AutoPostback enabled and both have an event handler for CheckChanged. I use tem to show/hide a Panel further down the form which is contained in an UpdatePanel with Conditional Update set and with both CheckedChanged events in the Triggers collection:
[Code]....
Now, the problem arises when I set the Checked property of either RadioButton in Page_Load, which results in the even not firing for the button which was marked as Checked (the event for the radio button whose property was not assigned does get fired). In fact, upon inspecting the source there was no 'onclick' attribute declared for the input element that was marked as checked in the Page_Load, whereas the other RadioButton did have the 'onclick' attribute properly set.
The layout of the form doesn't allow me to place the radio buttons within the UpdatePanel, so that is out of the question. Is the behavior explained above normal? am I missing anything? Both events fire once the assignment to the Checked property is removed from Page_Load.
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 one Datagrid with Footer. Footer Row Contains Input fields with one Button to add New Values. I have button click event but not getting fires. my code follows:
I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box
I have a CheckBoxList (CBL) control inside a gridview. The CBL viewstate is enabled and I populate the CBL items from a session variable with the following code
[Code].....
How can I maintain (save) the user CBL selection while postback ?
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
