Hi Experts,
In my aspx page , i need to display radio button lists from the xml input.
My xml is
<gas><level>Required</level><list><listitem i='0'>adress1, street1, state, zip </listitem><listitem i='1'>adress1, street1, state1, zip1 </listitem><listitem i='2'>adress2, street2, state2, zip2 </listitem><listitem i='3'>adress3, street3, state3, zip3 </listitem><listitem i='4'>adress4, street4, state4, zip4 </listitem></list></gas>

i need to get
radio button1 adress1, street1, state1, zip1
radio button2 adress2, street2, state2, zip2
radio button3 adress3, street3, state3, zip3
radio button4 adress4, street4, state3, zip4

if Radiobutton1 is selected , should display respective fields in
4 text boxes,
similarly for other radio buttons clicks.

Kind Regards,
Pooja

Here's a working model.

Arun

public class Data
{
    public string Key { get; set; }
    public string Value { get; set; }
}

XDocument doc = XDocument.Load(Server.MapPath("MyXml.xml"));

List<Data> dataSource = (from listitem in doc.Descendants("listitem")
                         select new Data
                                    {
                                        Key = listitem.Attribute("i").Value,
                                        Value = listitem.Value
                                    }).ToList();

rbList.DataSource = dataSource;
rbList.DataValueField = "Key";
rbList.DataTextField = "Value";
rbList.DataBind();

<asp:RadioButtonList ID="rbList" runat="server" />

Hello Pooja,

Please check the link:
http://niitdeveloper.blogspot.com/2010/08/generating-dynamic-controls-based-on.html

I tried for the code and hope I am able to do as you needed. I am trying to upload the code but network speed going slow. So it would take time but the code there is easy to understand.

Let us know back if your problem solved or not.

Hi Vs00saini,
Please find my code, I could get the event generated.

private void CreateRadioButtons(ArrayList elements)
{
for (int i = 0; i < elements.Count; i++)
{
RadioButton rbutton = new RadioButton();

string itemName = string.Empty;
string txtItem = string.Empty;
txtItem = elements[i].ToString();
itemName = itemName + (rbList.Items.Count + 1);

ListItem newListItem = new ListItem(string.Format("<b>{0}</b>", txtItem), itemName, true);

rbList.Items.Add(newListItem);

rbutton.CheckedChanged += new System.EventHandler(RadioButton_CheckedChanged);

}
}

private void RadioButton_CheckedChanged(object sender, EventArgs e)
{
RadioButton checkRadio = (RadioButton)sender;
String[] arrValues=new String[4];
arrValues = checkRadio.Text.Split(',');
if (arrValues.Length > 0)
{
//txtAddress.Text = arrValues[0].ToString();
//txtStreet.Text = arrValues[1].ToString();
//txtState.Text = arrValues[2].ToString();
//txtZip.Text = arrValues[3].ToString();
}
}

Kind Regards,
Pooja

Hi VS00saini,
I need some help and clarification. I some what dropped an idea of using xml since it ruled out my time . so i could get the source in dictionary and i could poup up the radio button list. i need to get the respective radio text selected when any any of the radio get clicked. i can send my code if u want.

Kind Regards,
Pooja

Hi,

Some doubts regarding your query:

(1) Popup the radiobutton list ... Do you want popup window to show radiobuttonlist.
(2) Get the source in dictionary ..... You mean to say the source of radiobuttonlist would come from Systen.Collections.Generic.Dictionary.

Hi Pooja,

I think I have done the coding as you mentioned in your statement. Modify it according to your requirements.
