look at the code below.btnCustomDateOk dosen't trigger postback at all.it's supposed to run a date range validator (javascript) first and if succeed then triggers a server-side event.(I've been testing around and when I replaced the button with a linkbutton, everything ran perfectly fine, wt? am I misusing the button control?)

I have a ListView (table inside) and it's first row are some TextBoxes for filtering actions.
In the last column I have a button that calls my Search function and filters the records according to the inputs.
[Code]....
My Search function for now only displays a text inside a Label at the top of the page.
When I load the page, I'm using ListViewPesquisa.DataBind() so it shows it's EmptyDataTemplate, but when I click the button inside the event isn't called at all. If I do put some data (any data) in the ListView and it shows it's LayoutTemplate instead, the event is called properly.
I can get around this issue by moving the filter line out of the table, but I'd like to know why is that the button inside the EmptyDataTemplate doesn't work.
I have created a simple modalpopupextender the extender has several options for the search functionality and when i press the okay button it supposed to do a search but.. it not...

PopupControlID="popUp"
DropShadow="true"
OkControlID="OkButton"
CancelControlID="CancelButton"

//code here--- not triggering

I built a webcontrol showing a complex user interface with a lot of javascript. Basically my webcontrol is similar to : [URL]
Now that most the user interface is working properly, I'm stuck with the following issue: I want to add a button (html button tag) which has to trigger an event. I have been able to declare the event, the event args, the delegate,etc. The page using my control may assign a handler and that handler is called correctly when I explicitely call OnServerControlClick (The name I gave to the event). I cannot make the link between the button in the user interface and the event in the webcontrol source code. When the button is clicked, I get an error message saying a dangerous Request.Form value has been detected.
I've created two buttons using javascript; yes and no. I need to get the event triggered when the button is clicked.i.e... onclick=getvalue().
public void SetYesButton(string msg_button_class) {
this.msgbox_Yes_button = "<input type="button" value="Yes" class="" + msg_button_class + "" onClick="getvalue()";>";
}
public void SetNoButton(string msg_button_class) {
this.msgbox_No_button = "<input type="button" value="No" class="" + msg_button_class + "" onClick="document.getElementById('pagedimmer').style.visibility = 'hidden'; document.getElementById('msgbox').style.visibility = 'hidden';">";
}
I create one set it contain three column in the 1st row with seven texbox having the name with Amount and 2 column with textbox(7) as qty and 3 column as totalamount(7).in the !st row i i will add the amount by coding.Now in the quantitytextbox i enter the amount and press enter means i got this error
Multiple controls with the same ID 'txtamount7' were found. FindControl requires that controls have unique IDs.
My code
void amounttextbox()
{
int number = 7;
for (int i = 1; i <= number; i++)

My application allows a team captain to enter the results of an 8-ball game then submit those results. In doing so the captain is brought to the next page to enter the results of the 9-ball game. But, there are games every week so there is a dropdownlist on both of the forms allowing the captain to select which date he/she is entering the information for. There are 14 weeks with the date displaying as the text value.
After the user selects the appropriate date and enters the results of the 8-ball game he is brought to the next form but he has to select the date again. Both forms ddl selectedindexchanged event enacts a whole lot of code which is required to allow the processing of the data.
I can capture the selected value from the first form and get it to the next form for 9-ball and even set the selectedvalue correctly, but that doesn't trigger the selectedindexchanged event. I want to put some code in the pageload to pass the selectedvalue to the selectedindexchanged event and trigger it to run with that value.
Is this even possible? I haven't been able to google my way out of this perdicament despite many hours of effort. And I know that users are going to spend 20 minutes entering all the data before realizing that they forgot to select the correct date in the ddl. What to do?
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.
In my ASP.NET app I have a control in the master page that raises an event Foo on certain occasions / interactions.I also have a couple of pages that have another control that must re-bind itself when this event is fired.Unfortunately the only way I can see them communicating between each other is by creating a long event chain (deriving a new MasterPage MasterPageSuperDuper, attaching an event handler to Foo's event in the user control, and then referring to this event in the masterpage from the control present in a couple of pages - basically using the masterpage as a control center).
View 2 RepliesI am working on windows form using C# language and I need to trigger the Checkbox's CheckedChanged event.
What code do I need to write to call or trigger this event.
I've been working on a web form that has lost it's ability to respond to most event handlers, though code that I write in Page_Load still fires. No button click or text changed events will fire. This has been working for months, and suddenly stopped. I did a windiff comparison to an older version of the webform, and don't see anything suspicious.

View 2 RepliesI have been strugling with this for a while and not gettting anywhere fast.I am trying to make a reorderable list using the AjaxtoolKit control ReorderList.It compiles fine and the select works, the problems come with the updates. When I try and reorder I get the following javascript warning: "Reorder failed, see details below.Couldn't find sort field 'ItemPos' in bound data."On investigating I can see that the update command it not being triggered. I can even remove it from the file code and nothing changes.So anyone any ideas what I do? I feel I need a handler in place but I cant seem to get that one figured out.The base code was taken from the toolkit examples and there is no code behind.Code Below:::::

I have a big form wrapped in an updatepanel (for other reasons). Inside this form is a section that needs to have it's own asynchronous postback -- there is a cascading dropdown and, based on the selections, you can add a product to a list. Once that list is populated, it can be submitted with the rest of the form.
So in this little section I have :
A Label for testing the button event (the label gets updated)5 Cascading Dropdowns (which are working fine)A button The button event changes the label text. If I click the button right away, it updates the label as expected. However, if I click the button *after* doing any selections on the Cascading Dropdowns, the label does not get updated. Things I have tried:
Removing the updatepanel surrounding the form -- yes, then the event gets fired, but I need it all in the updatepanel.Adding UpdateMode=Conditional -- no changeAdding an update panel just around this section -- no changeAdding Triggers either to the big updatepanel or to one just around this section -- no change
Thoughts?
I have a modal popup that comes and displays data. There is a requiredfieldvalidator and validationcalloutextender on each textfield control. I have a Submit Button (makes changes) and a Cancel Button (closes the modal). The problem is that validation is done on the cancel button. Even though the chancel will make no changes. This happens in all situations even when I'm not using the modal popup. How do I disable validation on certian onclicks???
