Hi one and all,

I need help. I have written a program regarding grid view with radio buttons.

Now what I need is if I did not select a radio box and click on delete button, I should get an alert like please select at least one.
If I select a radio box and click on delete, I would like to get an alert like Do you want to delete.

Can any one help me regarding this.

Thanks & Regards,
M.Dorababu

Got the required answer.

JavaScript

<script type="text/javascript">
function Validate() {  
var gv = document.getElementById("<%=GridView1.ClientID%>");  
var rbs = gv.getElementsByTagName("input");
            var flag = 0;  
for(var i=0; i < rbs.length; i++)
{
    if(rbs[i].type="radio")
    {
        if(rbs[i].checked)
        {
          flag=1;
          break;
        }
    }
}
  if(flag==0)
  {
    alert("Select one");
    return false;
  }
  else
  {
    return confirm('Are you sure you want to delete this record?');
  }
}
</script>

In page load write this

Button1.Attributes.Add("onclick", "javascript:return Validate()");

That's It

Solution 1

Sounds like a homework question to me?

In the delete button click event, do a check of the radio button checked state and or them together, if any of the values true then the result will be true.

e.g.

Java

if !(radio1state || radio2state || radio3state)
{
 alert("The message")
}

I'd suspect more that it's someone who is underskilled, doing paid work in an outsourcing house.
