When I Was Trying To causesvalidation=false for my server side validation control like requiredfieldvalidation.i want manually causesvalidation=false using javascript but i m not done.
View 2 RepliesI have a button on an ASP.NET page, and that button is (and needs to be) created via Javascript. The problem is, there are some validators on the page, and pressing the button is causing them to fire, and I don't want that to happen in this particular case. I am not sure what CausesValidation=false actually does on the page, but I was hoping to re-create it somehow.
I have been trying to locate the button by using a FindControl() statement in code-behind, but that doesn't seem to be working. If it did, I could just set the CausesValidation there...
I'm using VS 2010 targetting ASP.NET 3.5 and am using AJAX Control Toolkit 3.5.40412.
View 1 RepliesI have a regularexpression validator which validates a valid email. I have two buttons on my form. Submit and undo.On undo, we are reverting the page state to defaultsubmit has it validationgroup set while undo doesnot have any validationgroup and CausesValidation="false".Now when i navigate to page and enter invalid emailaddress,i directly click undo. the validator fires and stops my page from posting.however if i press tab and navigate to other control and then click undo,the validator shows error message but posts back and furthur proessing is done
View 3 RepliesI have a aspx page with two linkbuttons and a usercontrol. One is used to save and one to cancel.
But even though I add CausesValidation="false" on the cancel linkbutton it still validate the the validationcontrols in the user control.
But if I add a dummy linkbutton inside the user control that has CausesValidation="false" it works and postback without validating.
Why can't I have the link buttons outside the user control?
I have an ASP.NET text control "FromDate" whose visible property is set to false, but I wanted a client side javascript to be able to toggle the visibility property using CSS properties
element1.style.display = "none"; // hides the element
element1.style.display = ""; // shows the element
but when I attempt to get the textbox, I get null on
var element1 = document.getElementById("FromDate");
When I try the same code with visble=true as the default on the "FromDate" ASP.NET control, it works (although that is not the behavior I need)
I have build a composite control containing a Label, TextBox and a ImageButton. The idea:
Label text | textbox | imagebutton used for triggering an event
This textbox has a build-in validation.
When the imagebutton is set, i will use this imagebutton as a trigger. This imagebutton has an onclick event. Nou my problem is the following:
When i have my textbox on a form an click a button to validate my textbox validation takes place correctly.
If my textbox has the imagebutton enabled and i click this imagebutton validation takes place.
In my composite control i have implicity set imagebutton.CausesValidation = false;
Is it possible to update an UpdatePanel manually using JavaScript or jQuery?
What I have is a TextBox at the top of my page. When a user leaves that TextBox I want to run some server code (it will add a record to my database) then at the bottom of the page I have an UpdatePanel which will get refreshed. The UpdatePanel has a GridView which will have an entry for the record added)
Is it possible to manually fire a AJAX postback from Javascript.
View 4 RepliesI encouter some postback issue when using GetPostBackEventReference. Here is the Scenario:I have a javascript modal popup dialog and got a button in this modal dialog which used to select things (this is NOT an asp:button control)
When this javascript dialog HTML button is clicked, it will call the MS AJAX web service call by the javascript: eval() method. And this MS AJAX web service call is dynamically generated. So the code is like this:
var serviceCall = svcCall + "(" + parameters + ")"; //dynamically generate the MS AJAX web service call here
eval(serviceCall);
//use eval to trigger the MS AJAX web service call
As you may all know, after complete the MS AJAX web service, you can define a callback function to handle the completion:
function OnComplete(result, userContext, methodName) {
//force to call postback manually
eval($(userContext[0]).val()); [code]...
As you can see, this is how I bound the asp:button (i.e. btnSelectUser) 's Click Event to the asp:hiddenfield using the GetPostBackEventReference, and set the registerForEventValidation argument to false. I have also tried to use different ValidationGroup and set the CausesValidation to false.In summarize, I bound the asp:button's Click PostBackEventReference(i.e. __doPostback(....)) to the asp:hidden field's Value attribute, and using javascript eval() to eval this hidden field's value in order to manually trigger postback.
p.s. the btnSelectUser is an asp:button control and used to call out the javascript modal dialog.
Ok, here is the Problem:In the same page, there is some asp:validator, e.g. and , and of coz, when the page run into error, this validator and callout will display to the user. e.g. When the user didn't fill in anything and submit the form, the ValidatorCalloutExtender will display a ballon and tell the user. Imagine one of this ballon/validatorCalloutExtender come out and on top of your screen at the moment.
Then you click the btnSelectUser (asp:button) to show the javascript modal dialog, and in the dialog, you Add some users, and once you hit the SELECT button inside this modal dialog, a MS AJAX web service is trigger as mentioned above, and once this web service is complete, it eval() the asp:hidden field's value (i.e. __doPostback(...))......and do the postback manually.
However, because of the validatorCalloutExtender ballon has display, it somehow cannot trigger the postback in this way, but when I close the ballon/validatorCalloutExtender, the manual postback using eval() is just working fine. Even more strange is that, when the ballon is displayed, the first time I click the SELECT button inside this modal dialog it doesn't fire the postback, however, if I do the same thing again (i.e. open up the javascript dialog, and choose some users, then click the SELECT button again). It able to do the manual postback....and I don't understand why the first time doesn't work.
I have a large ASP.NET page with many TextBoxes and Validators The problem is that when I click on a button, I want to fire the validation for certain TextBoxes (but not all of them). And when I click on another button, I want to fire all of the validators.
View 1 RepliesddlOptions is drop down list selectedOptions is repeater control and it's just provisional code of my final control.
What I want to do is to get data for _ddlOption on !IsPostBack. There is Add button that enables user to move selected drop down item to repeater control.
It the following way of updating Repeater.Items correct? I found many solution of adding/removing elements manually using DataSource, but here my DataSource is null, as I set it only on !IsPostBack.

I have a FormView control with Two text Boxes. Data source for the Controls is an ObjectDataSource
I want to fetch these values from both text boxes, create a User object and pass it to ObjectDataSource, which has an input method that accept a User object
I think I have to do it in
protected void ObjectDataSourceUsert_Inserting(object sender, ObjectDataSourceMethodEventArgs e)
{
// string _userName = FormViewUserDetails. ?
// string _password = FormViewUserDetails. ?
User user = new User {UserName = _userName, Password = _password};
e.InputParameters.Add(user);
}
I am using the ASP.NET login control. I want to be able to set the timeout for Forms Authentication individually for each user (instead of globally in the web.config). From what I understand the only way to do this is to set the timeout on the AuthenticationTicket manually. Is there a way to do this when using the Login Control? It seems to me that the Login Control abstracts away all of this. I am hoping that there is some way to continue using the Login Control, but also have the ability to set the FormsAuthentication timeout individually for each user.

I have on site three textbox controls, RequiredFieldValidator with each textbox and button (without any code). I have problem, when I set autopostback property of textbox controls to true. Regardless, that EnableClientScript sets to true or false, validation error dissapears - or show only few seconds. Helps only set CausesValidation property of textbox to true. And my question - if autopostback is set to true, should I set causesvalidation to true too to make proper validation process? Why it doesn't work?

I'm a new developer here, working in VB. Have a question that is stumping me as well as some others.
I have a gridview control built. I am not using an <sqldatasource> tag, so I can't use it's autoGenerateSelect/Update/Delete functionality. I have built a template field that has an "edit" link button in it, and by clicking it will fire the grdName_SelectedIndexChanged event of the gridview.
Now, it's in this event where I'm having trouble. I have it coded so that when this event fires, it will build a textbox and button control. Code:
Protected Sub grdResults2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdResults2.SelectedIndexChanged
Dim row As GridViewRow = grdResults2.SelectedRow
Dim cell As TableCell = row.Cells(6)
Dim txtSeq As New TextBox
Dim btnUpdate As New Button
'build the textbox in the Search_Seq cell
txtSeq.ID = "txtSeq"
txtSeq.Width = Unit.Pixel(20)
txtSeq.Text = row.Cells(6).Text
cell.Controls.Add(txtSeq)
'build the "update" button in the Search_Seq cell
btnUpdate.ID = "btnUpdate"
btnUpdate.Text = "Update"
cell.Controls.Add(btnUpdate)
End Sub
So the textbox and button populate perfectly. I can run it in the browser and it works fine.
How do I go about setting up the event for this button now? Because it's being manually built here in the gridview event, there is no button for me to "double_click" on in the design view to auto-build this event. There are some properties that need to be set on this button to link it up to a new event....and that's where I'm lost.
Hopefully I don't leave any additional information out.
i have following issue: I am creating a new user register form manually without CreateUserWizard control, and all works perfectly unitil I intentionaly (for test purposes) enter existing username (for example BLABLABLA) into username.textbox. After that i get my error message as expected that says "username BLABLABLA allready exist", now when I tray (as a future user who could be in the same situation) to correct the username and enter another one (for example TRATRATRA), it still gives me this error "username BLABLABLA allready exist!" This is the second day that I'm traying to solve this!

I'm currently developing an ASP.net application w/ VB as the code behind. I have a page that shows all the user name currently assigned to the system. The problem now is that the page does not communicate directly to the database. Instead, I use HTTPrequest to get all the user names from a different sever. Now I want to populate the listview control w/ the response that I got (and not directly from the database).
