I'd like to set one of a few radiobuttons to checked dynamically. They are called rbTheme1-rbTheme7. I can find them (for example the one called rbTheme3) with the code below but how do I set it to true at the loading of the page?
int buttonID = 3;
string buttonName = "rbTheme";
(RadioButton)themePick.FindControl("buttonName" + buttonID.ToString());

I am creating a control that inherits from the RadioButton, so that I can set the GroupName property manually. Everything is working okay apart from the fact that when the page posts back, the RadioButton becomes unchecked if it has previously been checked. This is the first time I've tried inheriting from controls, so must be doing something really silly. I would welcome anyone helping me to improve my code so that the control's Checked value persists through postbacks. I am causing a postback using a button, not the actual RadioButton itself, if that makes any difference. Here is my code:

I have a couple of RadioButtons that are created dynamically. But after postback they don't retain their checked property. I also have some CheckBoxes and they work just fine using the same mechanism (code below). I have narrowed down the problem to the "GroupName" property. If I remove it, it works just fine. But I need the RadioButtons to be mutually exclusive.

I have a radiobutton and if it is checked "Yes", then the three textboxes that are disabled in default will be enable. Now that this textboxes are enabled I want this to be mandatory. How could I do this via javascript or code behind? If I do it in code behind then autopostback is need which is unnecessary.

So I've got three RadioButtons, They're not in a RadioButtonList because I need to add some textboxes next to each of them.I've added a GroupName, and on the front end they behave as expected. ONLY ONE appears checked at a time.However in the code, if I do:
RadioButton1.Checked = true;
RadioButton2.Checked = true;
RadioButton3.Checked = true;
I would expect only the last one, RadioButton3, to be checked, because they all belong to the same group. This is not the case. All three evaluate to true.... how can that be?

I have group of radio buttons, each group ranges from 5 - 27 radiobuttons. And if any radio button in a group is checked I store 1 in db else I store 0. Now I'm checking each radiobutton using if loop to see if they are checked and set database value. I'm also trying to use the code below. Is there a good/better approach to check if they are checked or not?Current code:
'rname is radiobutton prefix for a given group
'cnt is number of radiobuttons in the group
Private Function RadioIsChecked(ByVal rname As String, ByVal cnt As Integer) As Integer

I a using Gridview bind to a dataset. For this example, I am only setting up two columns.
1. Edit button
2. A template field that will display "No" and in Edit mode will show a checkbox.
When I run this code... the page is displayed... I click on the edit button... the row changes to edit mode and I CLICK the checkbox (can see a it checked).Then click on "Update" Button... which takes me to GridView1_RowUpdating event. If I check the status of the "box"... it's checked status is ALWAYS false Why?

I came across the following given a asp.net page containing
<div id='test'>
<input type='checkbox' id='ch1' name='ch1' runat=server />
<input type="button" id="view_test" />
</div>
and the following jquery code to show this div in a dialog
$("#view_test").click(function() {
$("#test").dialog({ show: 'slide', width: 600, title: 'View Check' });
});
If view_test button was clicked, initializing the dialog, before the form post backs the checkbox ch1.Checked property in .Net is always False. However if you just postback without initializing the dialog it works as expected.

There is a Gridview in my web page with select button as below:
<div class="test01" style="height:200px;overflow-y:scroll;overflow-x:hidden" align="center">
<asp:GridView Width="100%" ID="GAsset" runat="server" AutoGenerateColumns="False" DataKeyNames="AssetId">
<Columns>
<asp:BoundField DataField="AssetId" HeaderText="AssetId"/>
<asp:BoundField DataField="AssetName" HeaderText="Asset Name"/>
[Code] ....
When I am selecting any row of Gridview using checkbox and clicking on "Select" button, It is showing ch.checked= false
code is below:
protected void btnSelect_Click(object sender, EventArgs e) {
foreach (GridViewRow row in GAsset.Rows) {
CheckBox ch = (CheckBox)row.FindControl("chkSelect");
if (ch.Checked && ch != null) {
string key = Convert.ToString(GAsset.DataKeys[row.RowIndex].Value);
[Code]....
I also tried debugging my code using break points but it is showing ch.Checked = false everytime, dont know why.

convert.toboolean(request.form["mycheckbox"]
but since the value is 'false', it doesn't seem to cast to boolean. What should I do? I don't like checking for == "false" and then converting to boolean. is there a cleaner way? Update All I am doing is:
if (Convert.ToBoolean(request.Form["somecheckbox"]))
{

I have a datagrid setup where I have a column of checkboxes setup, several informational columns for the user, and a hidden ID column. I have set up the loop to check with checkboxes have been checked, but I am having troubles finding the ID of the row that has been checked. The following code results in a "Object reference not set to an instance of an object" error:
For Each row As GridViewRow In GridView1.Rows
Dim cb As CheckBox = row.FindControl("ParticipantSelector")
If cb IsNot Nothing AndAlso cb.Checked Then
Dim productID As Integer
productID = CType(row.FindControl("ID"), Label).Text
Response.Write("You have selected " & productID & "<br>")
End If
Next
I am sure that I don't have something right here.

In a asp.net mvc form, im using a radiobutton set, to set a property.
<%=Html.RadioButton("Tipo", "Pizza",
CType(Model.Tipo = "Pizza", Boolean), New With {.id = "Pizza"})%>
<label for="Pizza">Tipo Pizza</label>
<%=Html.RadioButton("Tipo", "Barra",
CType(Model.Tipo = "Barra", Boolean), New With {.id = "Barra"})%>
<label for="Barra">Tipo Barra</label>
I need the CType or i get an overload error. This case seems like the most commom use of radiobutton when working with a Model property. Of course i could create a partial view or a control, but apart from that, is there a cleaner code to accomplish this?
