View 1 RepliesI have all the code to save and all the code to validate. My question is will my code in the button(.aspx.vb) validate if my insert command is in the .aspx
View 3 Repliesi know this question have been mentioned alot here but mine is a little more updated, now with ASP.net 4 and new Ajax client templating plus JASON services. so if i got all these new capabilities will i really need server side controls as long as i can bind on client side, create data-views on client side heck i can even use data-context and apply CRUD operations on clients side.
so i actually i wont need button_click server side event or what so ever... i am asking this because i own some commercial Controls like Telerik and Component art and they both offer client side operations ow but still i am confused as to my knowledge creating these controls will still have to go through Page Life cycle

Anyway, if for example I have a textbox that I want to enable when the user check the desired checkbox/radiobutton, I like the textbox to be default enabled=false. What's the good approach between these two?
a.) client side

I need to know on the serverside, if a RadioButton has been disabled (by javascript) on the clientside.
The (serverside) Enabled property is not the same as the (clientside) disabled property. Using MyRadioButton.Attributes("disabled") doesn't do the trick either.

I have a link button inside a repeater. How would I directly call the serverside (ItemCommand) method during postback. I want to skip the page_load. The wierd thing happening is, if I put (!Postback) it doesn't execute other methods on postback but it does if I don't set the !postback condition. I have repeater inside a updatepanel in UserControl.
View 1 Repliesi have a gridview with commandbutton column and a textbox template column. My requirement is changing the text and hitting the enter key should also perform the same function as the command button. So i enabled the autopostback of the textbox.But if i click the command button after changing the text in the text box fires both the TextChanged event as well as the item command event. Is there anyway to bypass the Textbox text change event if i postback using the grid command button?

i have all the categories in my dataset. now i want my repeater to display it in alphabatically categories.
i have a form on a particular ASPX page that has custom js validation. Also on this form is a navigation menu in the header.
The navigation menu items are built programatically and are initiated by __doPostBack calls which obviously submits the form.
The problem i am having is that the form itself has code something like the following
onsubmit='return validateForm()'
and if the form has not been filled out then the form cant submit. This in itself is not a problem unless a user goes to the form but decides to navigate away.
When this happens the validateForm function fails.
Does anyone have a workaround for this issue?
NB: On my nav links i have already set CausesValidation="False"
This is the markup:
<div id="divNavigate" class="absolute_topleft">
<asp:LinkButton ID="linkGoHome" runat="server" OnClick="linkGoHome_Click" CausesValidation="false" CssClass="xxx">text.</asp:LinkButton>
</div>
This is the handler:
protected void linkGoHome_Click(object sender, EventArgs e)
{
Response.Redirect("xxxxx");
}
This is the validation function:
[Code]....
And this is how its called:
<form id="formLogin" runat="server" onsubmit="return validateTextField(field1)">
I have a problem with the ASP FileUpload control. It occurs in Safari and on websites where anonymous authentication is disabled and windows authentication is enabled.
When I select a file in the upload-control and then press an ASP-button the serverside event for the button is not triggered and PostBack is false.
Steps to reproduce the error:
1. Create a page with a file upload and a button. Print a message in the page's load event so you can see that if postback is true or false
2. Open IIS-manager and Add a new application that points to the folder where the page is
3. Disable Anonymous Authentication, ASP.NET Impersonation and Forms Authentication for the application
7. Enable Windows Authentication for the application
8. Browse to the page with Safari
9. Select a file with the upload control
10. Press Ok. Postback is false
If you then enable anonymous authentication on the web application and restart the browser postback works as expected.
