How To Retrieve The Values Of Controls In The Form That Posted
May 13, 2010
I know this has got to be the simplest-sounding question ever asked about ASP.Net but I'm baffled. I have a form wherein my visitor will enter name, address, etc. Then I am POSTing that form via the PostBackUrl property of my Submit button to another page, where the fields are supposed to be all re-formed into new hidden fields, then POSTed again to Paypal.
My problem is I cannot get at the values entered by the visitor in the original page. Any time I put in "runat='server'", ASP.Net completely changes the ID of the control, making it impossible to figure out how to access. In the POSTed form I tried Request.Form["_txtFirstName"] and that turned up null. Then I tried ((TextBox)PreviousPage.FindControl("_txtFirstName")).Text and that was null, too. I've tried variations on those. I cannot figure out how I'm supposed to get at these controls. Why does this stuff need to be so difficult?

I am creating an ASP.NET application that allows the user to add form elements to a page within a form. When the page is posted (via the submit button) I need to loop through ALL the posted values in the form and get the values.
I can't check for specific values as I don't know how many there will be or what they will be called.
Could someone point me in the right direction of getting ALL posted values so I can loop through them?
p.s I was looking in Request.Form but couldn't see anything obvious to use.

Simple question. I have an mvc controller that has method:
[code]....
The form is a non-trivial form with a simple textbox.
Question - how on earth do I access the parameter values? I am not posting from a View, the post is coming externally. I'm assuming there is a collection of key/value pairs I have access to. I tried Request.Params.Get("simpleTextBox"); but it returns error "Sorry, an error occurred while processing your request.".

I am building a DropDownList control dynamically. Constraining this discussion to within just the OnInit() method / state in the asp.net lifecycle, is the only way to see the dropdownlist's posted value to look at the Request.Form NameValueCollection? I m aware that the dropdownlist's viewstate is restored by the time OnLoad() is reached, but I need it's value before then (im pretty sure LoadViewState($object) is of no use?)

If I were using PHP I could submit a form to a new page, or the same page, and get the posted variables by doing something such as $_POST['txtVariable'], how do I do the same thing in ASP.NET? And is it possible to have more than one form per page?

The following action in my controller does not update the Model property which is bound by a radio buttons group (all are named "ListType") when the form is submitted. On the Edit.ASPX form, I used JQuery to reset the radio buttons group. When setting other type of input elements on the form to blank or checked=false, those Model properties are set accordingly upon submission. Does anyone know how to set radio buttons to unched state?
Also I am trying to get the SqlException to show up in my form where I have Html.ValidationSummary helper. My ModelState helper captures the know business rules violations, but I am unable to pass any SqlException and its Message property to this helper class due to unexected exception.

I have a datalist that is bound to a table in the database. I need to have a button for each item. Then, when users click that button I want to be able to retrieve information about that item. I have done this with gridview, but cannot seem to get it to work with a datalist. The only reason I am using a datalist is because I am able to arrange the items how I want and not be forced to have columns.
The way I have it setup so far is
<asp:DataList ID="dlFeeds" runat="server" OnItemCommand="dlFeeds_ItemCommand">

Some ids are pulled out from the XML field of a certain User Profile . Those ids have their text values stored in a SQL table.
What is the best way to map that xml list to the SQL table in order to populate a dropdown list which contains ids from the XML list and text values from the SQL table?

I use a ModalpopupExtender to show a dialog to the user which consist of a CheckBoxList control that is bound to a session table. The user can check/uncheck the CheckBoxList items and click the Ok control to close the ModalPopUp. How can I retrieve the values of the CheckBoxList items controls using JavaScript (seems like I cannot do it using server side scripting)?

I'm populating a dropdown box bound to an sqldatasource. From the sqldatasource, I'm retrieving locationID,locationType and LocationName.
The locationName is displayed in the dropdown. The selected values is set to, "locationID'. Based on the 'LocationID' the user is directed to a new page.
However, I need to pass the "locationID" and also the "LocationTYpe" values for the selected Name, so the sure can be directed to a specific page..how do I get BOTH values, 'locationID' and 'LocationType' when the user selects 'Location NAme' from drop down.

The method has a return type of collection<businessEntity>, i am calling the method from the aspx page in order to populate a drop down -> ddlDropDown. I am binding he DataTextField of the ddlDropDown with the BusinessEntity.Name and the DataValueField with BusinessEntity.Id, the business entity contains another id which is BusinessEntity.ProductId. I need to use the ProductId of the value selected in the drop down list in the code behind.
One possible way could be to call the method in the page_Load on the code behind and save the collection in a hidden variable and when required do a loop through in the hidden variable and retrieve the selected value Product Id.

how I access /retrieve values of checkboxlist inside a repeater? My code is below..is it the same as if it was not inside a repeater? My other concern is how do I distinguish these checkboxes because basically what 's going to happen here is based on which checkbox is selected I need to query an xml file to get the location of a folder which I'm then going to zip up and allow user to download..So here's the breakdown. I have an accordion panel using jquery ui. Each panel hold a product and each product has the same checkboxes..so depending on which product the user wants to download files for which he/she will indicate by opening the accordion panel for that product and checking which checkboxes/file they want to download . So how will I know which product the user clicked the checkboxes for being that I'm using this repeater which just one ID?
[Code]....
can I still use this code or will it not work cause it's inside a repeater..also I was going to use jquery to add an onclick event to the checkbox so how can I do that now with me using this control?
[Code]....
Here's another issue..I can't even assign values to the checkboxlist using databinding..so how am I suppose to do this.. Server Error in '/ArchitectView' Application. Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.ListItem does not have a DataBinding event.Source Error:

I was told to use a Repeater control in what I am doing which is a "Data Entry" screen with ASP.NET controls -a standard "address" like form. In cases, the fields on the form will repeated twice, once for the original values, one for the changed values. I have not used this control before but it seems like I have to bind to a database. Instead, I have an Entity object that has been obtained via a Repository. Can I bind to an object like this?
