    }



  
}

I have used two repeater in this, one for question,question Id and other for radio button to get data from database, but now i don't know how to save data that every radio button consist whenever user gonna check that option .

What I have tried:

I am trying for-each loop but don't know how to use it with nested repeater

protected void BtnSubmit_Click(object sender, EventArgs e)
{
var collection = Repeater0.Items.Count;

foreach (var item in collection)
{

}
}

Isn't it data-bound (the repeater)?

Member 11644373 20-Jun-17 4:59am

Yes it is

So? Just save your data source to the DB, changes should be delivered because of the bounded nature of the display...

Member 11644373 20-Jun-17 5:05am

I can't understand what you trying to say..let me clear my question actually i want whenever user click on any radio button from four options i want the option clicked to be saved into database whenever user click on submit button

Kornfeld Eliyahu Peter 20-Jun-17 5:10am

What I'm saying is this:
1. Your control is data bounded, so any changes to the control should be reflected on the data source
2. So when you are submitting the page, all you have left is to save the data source. You need not worry about updating the data source from the controls as it done because the data binding...
All that of course in case you done your binding right...

Simplest way is to read the answers from the Request. The "name" of your radio buttons are the question ID so if you Request.Form[QId] you'll get the selected answer

protected void BtnSubmit_Click(object sender, EventArgs e)
{
    var collection = Repeater0.Items;

    foreach (RepeaterItem item in collection)
    {
        HiddenField QID = (HiddenField)item.FindControl("QID");

        int q = int.Parse(QID.Value);

        string answer = Request.Form[q.ToString()];

    }
}

An alternative would be to use server-side radio buttons, or a radiobuttonlist, and access those controls programmatically.
