Get Value Of Selected Radiobutton In LoadViewState
Feb 3, 2010
can i get a value of a selected radio button in LoadViewState event of the the WebControl and how? All the components are generated in codebehind, so i have those controls:
RadioButtonList rbl;
ListItem liOne;
ListItem liTwo;
at the moment i am stuck at that the overriden LoadViewState is not being invoked
protected override void LoadViewState(object o)
{
action = rbl.SelectedValue;
action2 = rbl.SelectedItem.Value;
base.LoadViewState(o);
}

I would like to know how to connect radiobutton to the database. I use linq. To set the value from database to a text box is easy. I did like this.
<%= Html.TextBox("Headline", Model.Item.Headline,
new { size="35", maxlenght="50"
})%>
But I would like to know how to do for radiobuttonlist. This are my radiobuttons..
<%= Html.RadioButton("company_ad", 0,
true,
new { id =
"p_ad" })%>
<label
for="p_ad">Privatperson</label>
<%= Html.RadioButton("company_ad",
1, new { id =
"c_ad" })%>
<label
for="c_ad">F"retag</label>
How can I connect to the datbase like I did with the textbox above.

I have a vb.net page that has four radiobutton lists. In my code behind on each list, in the selectedindexchanged, I added the .ClearSelection on the other three radiobutton lists. But for some reason, when a radiobutton in list one is selected, if a value in list two had previously been selected, it remains selected, even with the .clearselection. Here's my code.. what am I missing?

I have a simple controller that sends a model/data to a View:
[Code]....
The View displays the data in a HTML Table:
[Code]....
This View displays the data correctly and provides a RadioButton for each row. When I select one of the RadioButtons the previous selection is removed as expected.
For now I am using an ActionLink to enter another Controller action. I have tried many ways without success to retrieve the selected RadioButton's value in this controller action.
[Code]....
I have also tried defining the Controller action with a parameter matching the model without success.

I've found this code, but I was wondering whether there's a more streamlined way to do it.
So for example, rather than having all the if statements can you have one line that says Label1.text = "You selected " & RadioGroup1.Text
Sub SubmitBtn_Click(Sender As Object, e As EventArgs)
If Radio1.Checked Then
Label1.Text = "You selected " & Radio1.Text
ElseIf Radio2.Checked Then

I have an update page with radiobutton "Alternate Addresses". If the radiobutton has "Yes" value, There would be altenate addresses for client. If radiobutton has "No" value, there won't be any alternate addresses. In update page, if supplier changes radiobutton value from "Yes" to "No" and clicks asp:Button "Update", all alternate addresses will be deleted. I want to show a confirm messagebox on Update button click. But i am not being able to retrieve radiobutton selected value in javascript.
var list = document.getElementById("radios"); //Client ID of the radiolist
var inputs = list.getElementsByTagName("input");
var selected;
for (var i = 0; i < inputs.length; i++)
{
if (inputs[i].checked)
{
selected = inputs[i];
break;
}
This code works fine with html buttons. But I want code for asp:Button onClientClick.

I cretated my own server control (a dropdownlist) and thus my own LoadViewState and SaveViewState methods. When is the LoadViewState called? I added the control to my page and looked when the methods are called. Only the SaveViewState is called when the page is requested, LoadViewState is not. Do I have to call it manually?

In a project of mine I dynamically create controls and add them to the nodes of a radtreeview (a control by telerik) in theLoadViewState event. By the end of this event everything seems fine, but as soon as the
Page_Load event fires the controls have disappeared. No code of mine is executed during this phase.
I'd love to know why this is the case,

Setup:
My page has a drop down whose values are dynamically populated. Based on which item is selected, a number of TextBoxes are dynamically created during runtime.The user then fills in information into the textboxes and clicks a submit button.
Problem:
After postback from the submit button, I need to again dynamically create the TextBoxes during Page_Init (BEFORE LoadViewState) so that after the ViewState loads, my Button_Click event can save/do whatever with the user input. PROBLEM is, I cannot recreate the textboxes based on the selection in the dropdown, because the dropdown hasn't been "selected" yet by LoadViewState.
SO, how can I read from the view state, create my textboxes, then let the viewstate populate the textboxes, and then the Button_Click will use the values??
The one thing I've attempted is to override the LoadViewState function so that I can read from the view state, create the boxes, and then load the viewstate again. This did NOT work, because the debugger never seemed to hit my overridden function.

I have an asp:RadioButtonList which is data bound. The list has two values. However the user has the ability to make the list invisible in which case I want to store a 3rd value in the data table. I want this third value to be completely invisible to the user. Originally I thought to add a 3rd "invisible" radio button which would become checked when the user deactivated the radio button list. However I can't find a suitable method of accomplishing this. My first question is: Does this solution make sense, or is there a better way of doing this, and second if it is a decent solution, how do I make the third radio button invisible in the code-behind on form load event?

I am using a client side validation and it is starting to get messy, considering I am making a form. With all the textbox and radio button validations, the controller will be overwhelmed. How do I validate and display the error Message for Radio Buttons and multiple textboxes in MVC on the MODEL side? A simplified version of what I have.
public class ModelData
{
public string ContactName { get; set; }
public string ContactAddress { get; set; }
public string ContactPhone { get; set; }
public bool RadioPoliceFire { get; set; }
public bool RadioComplaint { get; set; }
//The following is a Failure :(
public string RadioType
{
if (RadioType == null)
{return "Type Required";}
return null;
}
//End Failure
}
CONTROLLER...
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Info(ModelData InfoData)
{
if (infoData.RadioType == null)
{ModelState.AddModelError("RadioType", "Type Required");}
try
{ ...
return RedirectToAction("Confirmation");
catch
{ModelState.AddModelError("RadioComplaint", "Error");}
}
