Find radio button control in nested repeater control in asp.net? - asp.net

Question

I have two repeater controls one inside other and in inner repeater there is placeholder in which radio button is dynamically generated. I want to find the radio button control to check whether it is checked or not? I want above all function to be performed in button submit/click event defined in the code?

I found the answer. Thanks
foreach (RepeaterItem repeater in TabRepeater.Items)
{
Repeater repeater1 = (Repeater)repeater.FindControl("ContentRepeater");
foreach (RepeaterItem repItem in repeater1.Items)
{
for (int i = 1; i <= 4; i++)
{
string rdboption = ds.Tables[0].Rows[c][0].ToString() + "_" + ds.Tables[0].Rows[i - 1][2].ToString() + "_" + "Option" + i + "_" + i;
PlaceHolder PlPreview = (PlaceHolder)repItem.FindControl("PlPreview");
rbt = (RadioButton)PlPreview.FindControl(rdboption);
if (rbt.Checked)
{
// statement
}
}
}
}
}
}
