I am the beginner of using c# . .

In my project i used one gridview control with Input(Radio). If I select 1 radio then click select(Its a button).then selected radio button details are display the following textboxes. then i can modify it and store it..

My problem is suppose the user if doesn't choose the radio button, he directly click the select button without choosing a radio button in grid view the error will be occur .

Then my qustion is how to set validation for that button click.

Plz help me.. i don't know.. dis s correct or wrong..

Where is this select button? In grid row or outside grid?

Changed question title to meaningful description. Please do not use "Peace be upon u guys" or similar as it does not tell potential answerers what your problem is - that wastes time if they (in this case) know nothing about threading. If you use a more descriptive title, you will get better focussed responses.

You can use javascript function to check

function GetRadioButtonValue(id)
    var radio = document.getElementsByName(id);
    for (var j = 0; j < radio.length; j++)
        if (radio[j].checked)
