When posting a form in ASP.NET, it adds container information to the request form keys
For example if you have a Textbox field with an ID of: txtFullName
It could end up posting something like this: ctl00_ContentPlaceHolder1_txtFullName
This is fine if you control the page where you are posting to but if you are posting to someone else's page or API then the form keys have to be exact.
I'm looking for an example of how to post a pure HTML for via asp.net or via code in vb.net/c#
TIA
in ASP.Net 4 you have the ClientIDMode="Static" :)
but if you are still not on 4
you can use this solution:

but you have to be careful with it.
so just inherit the control you want like textbox and override this properties
and you should get the result you wanted.

I have following problem.
I have homepage with form , that have it's own logic , now I need to add a widget on this
page , what the widget should do , it's to post some Data Input from user to another aspx page.
Unfortunately I've came to ASP.NET from MVC (and have no idea how to do it in asp.net), and there I'd implement it by adding another form to page , that will post to Controller I need.
In ASP.NET I can't put another form with runat server attribute , can anyone advise the best way of implementing this task ?
Quite simple, and thanks to the magic of modelbinding not much that you have to do.

I'm creating a search form using an asp:button control with the urlpostback set to a results page. The problem is, the asp:button uses Visual Basic and the search results from Google require Javascript.
Is there a way to take the data from an asp: textbox in VB and then send it to another page that uses Javascript and use the data?
You can always save the search results into a hidden form field, and set the page's form option to post to your "destination" page. From there, you can use your typical JavaScript methods to pull the data out of the posted form.
I'm not sure if it helps you but its worth a try:

You could try
Response.Redirect - and redirect to google.com with the search query appended (as a test I just manupulated the string in my browser and it seems to work. Look at the querystring parameter "q"
Try the google search api
I'm struggling with an issue I just can find a solution for.
First of all, I can't use asp.net AJAX or anything else thant standard asp.net 2.0 as the server admin won't install anything else.
So here is, what I try to do. (For the curious, skip to the bold question below)
My page consists of several parts, each of which gets loaded by jquery.load(url). One of these page parts gets filled with an aspx that contains a form view. As I don't want to have postbacks, I switch to the EditTemplate of the form view by a simple click on a regular html button that submits a parameter indicating the aspx page to switch to edit mode, e.g.
Page_Load(...)
{
if(Request.Params["SwitchEditMode"]) SwitchEditMode();
}
This works perfectly! Now here the part where I'm stuck. The elements in the EditTemplate are based on a select from a database view and bound to the fields by <%# Bind("xx"). Then I have a html button (no asp control) that submits a parameter to the aspx page that tells it to invoke the DataSource update method. In the dataSource_updating method I look for the controls that contain the values I want to save. But these values are always the same, as when I switch to the edit view. No changes I make in the textboxes or dropdowns are preserved.
A long story short, the question how to save the values from EditTemplate back to the database with jquery?
Up to now I tried several approches, that didn't work out.
In the updating() method look for the controls by FindControl and set e.Command.Parameter["xyz"] = foundcontrol.SelectedValue;. The values are always the same as in the beginning.
Set <asp:parameter name="SampleValue" /> and in the EditTemplate <asp:TextBox Value='<%# Bind("SampleValue")#> The values are always null.
Set a hidden input field with the selected value via javascript. This doesn't work as the control within EditTemplate are only visible after the switch into edit mode
So maybe I'm totally wrong with my ideas, heading into a totally wrong direction and this can be accomplished much easier, but up to now I don't know how to achieve this. I could do it without ajax, but for the user experience I'd prefer the version with jquery.
For all that have read this far and not got confused :-), thanks for your effort!
Best regards,
Andreas
I would forget using a form view and just use a regular html form with regular input controls. Return an object from your web service that has all of your values and populate the controls with ajax and then subjmit with ajax. Either do fully asp.net or fully html/jquery with asmx back end. Otherwise it's just too confusing.
If you load both "modes" of the FormView into the same page using AJAX, you're probably getting duplicate field names. One of them contains the unchanged values which are being saved. How will ASP.NET know the difference? You only want to submit the ones from the EditTemplate, which will require a separate form (or some other hack).
Or perhaps your HTML submit button isn't giving ASP.NET what it needs to repopulate the controls. Are you using ViewState in the page with the FormView?
All in all, this sounds like a hairy combination of technologies... as you well know.
I am developing a form using all asp:textbox and asp:label. Currently, I am using the RequiredFieldValidator to validate text boxes and display an error inline. What I am trying to do is to change the color of one of the asp:labels after validation fails for one of the textboxes fields. Would I accomplish this with javascript, or is there any commands that can do it within asp to modify labels. I would really appreciate any help and code examples.
I'd say that javascript is the way forward here if you don't want to postback to the server. If you use ASP.NET only the page will normally have to be posted back so that the server can change the properties of the label - not very user friendly. A colleague of mine has accomplished this very nicely using JQuery (a javascript libraray) but unfortunatly I don't have a copy of the code to hand. He's an SO user too so I'll pass on a link to this post for you.
I have an ASP.NET page. What I want to do is pass in an ID field that is in the querystring.
So if my page is
http://www.mysite.com/default.aspx?id=35
I want a silverlight control that is on this page to have access to the id field. My silverlight control is going to get data for a grid and it needs to use the id.
You can use the HTML DOM Bridge to do that:
using System.Windows.Browser;
string queryString = HtmlPage.Document.DocumentUri.Query;
While this covers the concept in startup parameters (which is possibly what you are doing) here's a walk-through about it. http://silverlight.net/learn/learnvideo.aspx?video=72312
