Something strange is going on. I have requiredfieldvalidators on 2 textboxes. I enter data and I cannot click the asp button. but when i remove the validation group I can click the button.
[Code]....
There are 2 boxes within the group
And the lower button. Any ideas why this isn't working? I enter info into all textboxes and I still can't fire the button event. Remove the group and it's fine.
I have two asp.net buttons in my page.If i make button cause validation false then am able to
fire button click event on server side but not able to validate text box values(but i need to validate text boxes) using required field validator.
I am having a problem where my button click event is still firing even though my custom server-side validation is set to args.IsValid = false. I am debugging through the code and the validation is definitely being fired before the button click, and args.IsValid is definitely being set to false once the custom validation takes place, but it always makes its way to the button click event afterwards.
View 1 RepliesI have today developed a page that builds a series of RadioButtonLists, which may or may not be required fields.
As the page varies depending on DB values, I have rendered the controls using .RenderControl().
Unfortunatley I do not have the code to hand right now, but its along the lines of:
RadioButtonList rblQuestion = new RadioButtonList();
rblQuestion.id = question.ID;
// Add ListItems...
RequiredFieldValidator rfvQuestion = new RequiredFieldValidator();
rfvQuestion.ControlToValidate = rblQuestion.ID;
rfvQuestion.ErrorMessage = "*";
I then use .RenderControl on both rblQuestion and rfvQuestion, concatenate into a string then use the HTML String to populate a PlaceHolder.
This seems to work fine, all appears as expected apart from the RequiredFieldValidator - I get a red asterix (My ErrorMessage) next to each RadioButtonList - But this appears as soon as the page loads, not on a post/button click.
Is anyone other than myself having issues with client validation not working all the time? I have MVC3 RTM installed. I'm looking at the LogOn view created with a new Internet Application with the razor engine. Both the User name and Password fields both have the Required attribute. If it enter asdf for the username and asdf for the password and go back and delete the values for both of them, only the error message for the password field comes on. If I keep entering values and deleting them, the validation will eventually trigger for the user name field.
View 3 RepliesI've got the following View

The problem is that when I submit a blank form back to the controller, I get redirected to the "its valid" page, meaning that the form passed validation.
What might I be doing wrong?
I have few controls which r validated for blank on a page having 5 buttons
I want the validation to take place only on save button click & not on any other button
<asp:ValidationSummary ID="ValidationSummary1" HeaderText="You must enter a value in the following fields:"
EnableClientScript="true" ShowMessageBox="true" ShowSummary="false" DisplayMode="BulletList"
runat="server" />
I have a set of validation controls on my asp.net page, to validate values in textfields. I also have a calendar control on the same page. When I click on the calendar image, the validation control message box pops up. How can I avoid that from appearing when the calendar icon is clicked?
View 2 RepliesI have this code:
protected void registerBtn_click(object s, EventArgs e)
{
bool agencyPictureActive = agencypicture.HasFile;
agencypictureValidator.Enabled = agencyPictureActive;
Page.Validate();
if (Page.IsValid)
{
and this control:
<asp:label runat="server">Logo</asp:label>
<asp:FileUpload id="agencypicture" runat="server"/>
<asp:CustomValidator id="agencypictureValidator"
ValidationGroup="userForm"
ControlToValidate="agencypicture"
ErrorMessage="some error msg" Text="*"
OnServerValidate="checkImageSizeValidate"
runat="server">
</asp:CustomValidator>
I want to validate and save the image along with other form value upon "registerBtn_click" , but the custom validation control of the image does not activate somehow... why?
This is my submit control:
<asp:LinkButton id="btnSubmit" OnClick="registerBtn_click"
ValidationGroup="userForm" Text="Submit" runat="server">
</asp:LinkButton>
Button click is not firing for some reason. This button is in a content page.(Master page)
I am not sure what is happening.
I'm facing a weird issue...My button events are not firing :(I'm using the 3.5 .net framework and I've already tried to run aspnet_regiis -c, clear the browser temp files, use windows integrated authentication, but nothing works...this is the cenario:
- windows server 2003
- app migrated from .net framework 1.1 (which was working fine) to .net framework 3.5
- IE8
If my ASP.NET button starts out visible to the client, it works just fine when clicked:
<asp:ImageButton ID="btn_Submit" ImageUrl="~/images/submit.png" runat="server" onclick="btn_Submit_Click" />
However, if the button was inside a hidden div to start it does not fire after being revealed:
<div style="display: none;" id="hiddenDiv">
<asp:ImageButton ID="btn_Submit" ImageUrl="~/images/submit.png" runat="server" onclick="btn_Submit_Click" />
</div>
The DIV is unhidden with jQuery ($('#hiddenDiv').show()). Why would the button work when it starts out visible, but not when it started out hidden and was made visible in jQuery?
I have a custom validator:
<asp:CustomValidator ID="QuestionValidator" runat="server" ErrorMessage="Please select an option" ClientValidationFunction="QuestionValidator_ServerValidate" OnServerValidate="QuestionValidator_ServerValidate" ValidateEmptyText="true"></asp:CustomValidator>

When I run the page, there is no validation and no error message. Please can you point out where I am going wrong, I'm suspicious it is at Page.Master.FindControl("form1").Controls.I have previously done such validation by looping through controls via form1.controls but this is unavailable as the page uses a form passed down via the master page.
I have a webfrom on which I have some textbox controls, validation controls and button controls. When I click the button is validating the form but when I fill the text boxes with valid data and click the button nothing is happening i.e. the page is not posting back and button_onclick event is not firing. Below is the markup.

I am using vs 2008 in my wepage i have one update button which is not fired in first click i deleted all coding and tried for this simple line coding for this also not firing in first click

I'm having the all fun issue of the SelectIndexChanged handler firing on the button click of the submit button on the page. I have up to 5 dropdownlists on the page and show them based on a procedure from the users type. I also turn the autopostback on and off depending on how many ddl's are on the page. I have tried adding the EnabledViewState on the updatepanel, ddl controls, etc to no evail. Is there a simple fix for this?
View 2 RepliesI am designing a page wherein I want to display just parts of a page on page_load (i.e. menu bar). Then a few seconds later, I would like to display the rest of the controls (i.e. charts). Is this possible? What I currently have is a page that displays the page skeleton and then on button_click(), the rest of the page is rendered. I want to fire a button_click() event on code-behind without actually requiring the user to click on the button but can't seem to find good tutorials/articles regarding this approach.

I have several buttons on a page, but have assigned some validators and AJAX validator callout extenders to one button in particular. However, the validator callout extenders seem to be firing even if I press a different button. I thought this was the point of setting a TargetControlID (for the valiator callout extender) and a ControlToValidate for the validator itself!

View 4 RepliesI am having an odd situation with a dynamic image button. This button is part of a dynamically built asp table which lives in a repeater. Not sure if that complicates things or not, but here's the issue. Since the buttons are dynamically built, if I let asp.net handle the ids I get a crash on postback. Not entirely sure why, but If I set the id in code, I don't get the duplicate id error but I don't get the event fired either. Here is the code building the button:

With this code the IB_Validate_Click never fires. If I comment out the IB_Validate.ID line, the event fires. But, as mentioned above, I have an id clash on a postback. Any ideas why the IB_Validate_Click doesn't fire on this button if the id is set?
I have a link button which is part of my user control. Further, the control is actually added to the control dynamically. Whilst, I can see the control, and is added to the page without any visible errors, but when I click on to fire an event which on that user control nothing happens. What is even more odd, if I add a break point to event, and then click in debug mode, I can't even reach the break point!
To try and resolve this, I have tried giving the link button ids, and ensured they unique, added override using OnInit and used the createchildcontrols method, but nothing seems to work!
I have a accordion control inside an update panel. As I loop through the Products table and the Details table in the code behind, I'm creating the accordion panes that will display the data. There's an "Add to Cart" button created for each product (each accordion pane), and I'm asigning an EventHandler for that button, but it never fires... Here's the code where I'm creating and adding the button to the page:

I've got a .net button that has an href attribute value set to
javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$cp1$ucInvoiceSearch$btnSearch", "", true, "", "", false, true))
I've got a textbox that when I press enter I want it to fire this event. Doing the 'Enter' event isn't an issue but I can't get the event on the href to fire using .click(). Here's my function so far:
$("[id*='tbInvNo']").keyup(function(event){
var $btn = $(".pnl-invoice-search");
if(event.keyCode == 13)
$btn.click();
});
I have a UserControl, which has few textboxes, RequiredFieldValidator and a submit button. Every thing was working fine and now suddenly the button click event stopped working.If i set the CauseValidation= false for button, then it s working fine, but i can not do that because i want user to enter some value in the textbox.I investigated that it might be RequiredFieldValidatoe which is stopping the button to postback, but why its doing like that if you have entered the values in textboxes.
