AJAX :: CheckBox Inside Updatepanel CheckedChanged Event Not Firing?

Mar 11, 2011

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.

for (int
i = 0; i < cnumber + 1; i++){
chkresponse[i] = new System.Web.UI.WebControls.CheckBox();

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

{Label1.Text = "response";}

CheckedChanged EventHandler Of Dynamically Added Checkboxes Not Firing Inside UpdatePanel Of A Repeater

Jul 15, 2010

I´m using a Repeater to generate Items out of a Database. Each ReapeaterItem should include an UpdatePanel, because i have to Update the Controls inside the UpdatePanel and do not want to reload the complete page. Inside these dynamically generated UpdatePanels (each RepeaterItem has one) i´m adding up to three Checkboxes dynamically (based on the Database). These Checkboxes need to fire the "CheckedChanged" event, because on some conditions i want to enable/disable/check/uncheck Checkbox1, 2 or 3 based on business logic. ... Hope you got this so far. I´m adding all Controls and have the EventHandler Added. But the generated Code does not reflect the Event Handler. I tried OnItemDataBound, OnItemCreated, PreRender, ... Events to add the Eventhandler too, but i was not able to find the CheckBox-Control with the ID.

I´m totally lost with this and on the way to use Buttons instead of Checkboxes. From what i read so far is that with Buttons i can use the CommandName from the Button and the ItemCommand-Event from the Repeater to get a workaround, but then i need to reflect the "Check" on the Page in some way. btw, every Repeater (8) sits inside an ajaxtoolkit-accordion control. Here i give you some Code:

aspx-Page
<asp:Repeater ID="RepeaterAccordionPane2" runat="server">
<ItemTemplate>
HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Header")%>HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Beschreibung")%></td>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode=Conditional>
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
HTML Stuff
</ItemTemplate>
</asp:Repeater>

Here is the Page_Load Part

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dvAlleArtikel = new System.Data.DataView(...Database...);
[... some other code here ...]
RepeaterAccordionPane2.DataSource = dvAlleArtikel;
//RepeaterAccordionPane2.ItemCreated +=new RepeaterItemEventHandler(RepeaterAccordionPane2_ItemCreated);
//RepeaterAccordionPane2.PreRender +=new EventHandler(RepeaterAccordionPane2_PreRender);
RepeaterAccordionPane2.DataBind();
int nUpdatePanelIndex = 0;
foreach (Control crInRepeater in RepeaterAccordionPane2.Controls)
{
if (crInRepeater.GetType() == typeof(RepeaterItem))
{
foreach (Control crInRepeaterItem in crInRepeater.Controls)............

C# - GridView 'CheckedChanged' Event Only Firing Once?

Mar 1, 2011

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.

EDIT: Bit of code:

<asp:CheckBox ID="chkIncludedLocal" runat="server" Checked='<%# Bind("Included") %>'
Enabled="true" OnCheckedChanged="chkIncludedLocal_CheckedChanged" />

And in the event, I put a breakpoint right at the top to see how many times it fires

Web Forms :: CheckedChanged Event Not Firing When Checked Property Set On Page_Load

Jul 21, 2010

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.

Viewstate - CheckBox Does Not Fire CheckedChanged Event When Unchecking?

Aug 11, 2010

I have a CheckBox on an ASP.NET Content Form like so:

<asp:CheckBox runat="server" ID="chkTest" AutoPostBack="true" OnCheckedChanged="chkTest_CheckedChanged" />

In my code behind I have the following method:

protected void chkTest_CheckedChanged(object sender, EventArgs e)
{
}

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.

Forms Data Controls :: Gridview / Adding CheckBox In RowDataBound - CheckedChanged Event Not Fired - Page Lifecycle

Jan 5, 2011

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:

protected void Page_Load(object sender, EventArgs e) {
LoadGrid();
}

But this is very expensive and causes that the db request will be executed twice. If I changed the code to what I want:

protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack)
loadGrid();
}

I get no CheckedChanged event.

Is there a possibility to get:

- Adding a Checkbox in RowDataBound
- Only "LoadGrid()" if it is no PostBack
- Getting the CheckedChanged event of the relevant row

Forms Data Controls :: CheckBox Checked Changed Event Is Firing For Every Control Event?

May 8, 2010

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.

Forms Data Controls :: NumericUpDownExtender Inside UpdatePanel Firing Twice?

May 2, 2010

I have an UpdatePanel which has inside a detailsview, this DetailsView has a TemplateColumn with a UserControl.The UserControl has a NumericUpDownExtender and when the user clicks on an arrow or changes the value of the textbox a server event is raised (this is made by me, not default behaviour). I do this by using the add_currentChanged of the extender (in the javascript pageLoad function, and remove_currentChanged (in the javascript pageUnload function) and implementing the interface ICallbackEventHandler in the UserControl. My problem is that when the user click on the arrow, the event is raised twice and the correct value is overwritten.
