I have a WebBrowser on my form and once the page is loaded and some content is extracted, I call Refresh() method but I'm getting this error from page:
How can I confirm this resubmission automatically and programmatically?
Note on buttons' text translation:
Repetir = Repeat
Cancelar = Cancel
If it's an option, try doing an AJAX post and checking on the response.
Could you simply change the URL in the WebBrowser to the same page, rather than refreshing?
If all you are doing is trying to load content, rather than actually displaying something - you could try Watin. http://watin.org/
I have a situation where I'm not sure if I should use a HyperLink or LinkButton. When a user clicks on a list of links I want to trigger a click event where I save some information to session (should use LinkButton) but I also want these links to open up new tabs (should use HyperLink).
A LinkButton will postback, it's essentially a button that renders like a link. You could set a response.redirect(url) in the event handler to set a new tab.
Can you add more information, of what you want to do in the handler, maybe this could be achieved with Jquery calling a server-side method?
Difference between Hyperlink and LinkButton
Click Api with Jquery and Jquery post.
You will need to use a LinkButton which causes a PostBack. To open additional tabs, emit JavaScript.
protected void MyLinkButton_Click(object sender, EventArgs e)
{
Session["MyData"] = 123;
Page.ClientScript.RegisterStartupScript(Page.GetType(),
"newWindow",
"window.open('http://myurl','_blank');",
true);
}
I would say a HyperLink that hits a specific URL to store the necessary session data, then use Response.Redirect to redirect to the following page after storing the information.
The HyperLink's URL would point to your server so that you can store the information, and then you would use a redirect to point the user to the correct endpoint after storing the necessary data.
Example
HyperLink's URL points to ~/yourpage.aspx?state=NY, with target="_blank"
Server responds to URL and checks querystring.
If query string exists, store data (if (Request.QueryString["state"] != null) Session["state"] = Request.QueryString["state"])
Redirect the user to the appropriate URL (Response.Redirect("http://www.ny.gov"))
If the data is at all confidential, then you would want to use the LinkButton methods pointed out in other answers. Opening up a new tab is tricky, so you would probably have to write out some Javascript as outlined in #andleer's answer since I don't believe there is an easy way to pop open a new window from the server side otherwise.
You need to use LinkButton.
The difference between the two is that LinkButton postbacks your page to the server allowing you to make your logic while HyperLink does not postbacks - just redirects you to the specified link, therefore, use HyperLink when you want to navigate.
The LinkButton control is used to create a hyperlink button. This control looks like a HyperLink control but has the same functionality as the Button control.
with LinkButton you also get the facility of Web Control Standard Properties and Control Standard Properties .
You're right, can't do both, since a LinkButton will trigger a postback, and a hyperlink will simply navigate to a new page.
In your case use you can use a LinkButton and the server code will have to to do a redirect (if you want to navigate to another page) or handle the Tabs and return the page with the Tab opened if you are using a tabs element. (so the tab navigation will not be done front end)
In such cases you can use button for saving some information and you can also use it as a like option. But if you want to add a link then you have to use hyperlink.. You can also use javascript to link a url with the button so that when user clicks on that button the session information will get stored and then he will redirected to the new webpage.
I have a button in my aspx page, which in code behind the value of postbackurl gets set. I updated the code to add click event handler and added Response.Redirect code to redirect user to the page once the button is clicked. The only reason i ended up adding click event was because i had to add some extra logic when the button was clicked including redirecting to same url, that was used in postbackurl. The page does get redirected on click however it seems like all the hidden fields from the field gets lost once the form get redirected to the url.
Is there anyway i can submit the form without loosing the hidden data.?
Maybe one way you can solve this problem is to use the server side Transfer() call.

In most cases I've seen what you really want to do is pass the information for the new page using URL parameters. Take all the stuff the new page needs and put it into the url (encrypt if it is security sensitive).
If the only issue you are having is when you want to stay on the same page, this is simple, just have the click event handler return without doing a response.redirect or a transfer.
Post the code if this is not working for you.
I have a web page that prompts for user input via DropDownLists in some table cells. When a selection is made the selection replaces the DropDownList so that the action can only be performed once. In the case that a change needs to be made I want to be able to click a button that reloads the page from scratch. I have Googled and Googled but I have not managed to find a way to do this.
Any advice is appreciated.
Regards.
Put a link on the page with the text "Reload" and the url the url of the page. It's perfectly valid to have a page with a link to itself.
If you don't like the link idea, use a standard Button and in the click event, use Response.Redirect to redirect to the current page.
You can set an OnClick for your button that resets each DropDownList's SelectedIndex to 0 instead of reloading the page from scratch. Alternatively, you can set a Response.Redirect([the page's url]) into the OnClick as is suggested here.
I have a gridview where one column is going to be a hyperlink that will open a new browswer window and display a file so upon clicking this link I am currently using the NavigateUrl and calling a new page and setting the target to blank. My problem is that in this new page I will need to know the ID of the row that was selected. How can I pass this information? Querystring doesn't seem to work?
Check out HyperLinkField's NavigateUrlFormatString property here.
Instead of using NaviagteURL use a click event, add a session variable, and response redirect to the page. Look for it in the page load on the new page.
