I have a gridview with checkbox and textbox. Id like to put in validation that would check for either checkbox = checked and textbox left empty and/or checkbox not checked and textbox has values.

How can i do it?

This is layout:

This validation would happen when i press submit. I cant figure out how to do it and i have no knowlege of javascript.

Please help.

THank You

Hi Kev Patil,

function Validate(chkBox,txtBox)
{
var value=document.getElementById("<%= txtBox.ClientID%>").value;
if(chkBox.checked && value=="")
{
alert("logic 1 ");
}
else if(!chkBox.checked && value!="") {
alert("logic 2 ");
}
}

On the GridView event Add the below code

OnRowDataBound="GridView1_RowDataBound"

on code behind file add

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType==DataControlRowType.Header)
{
CheckBox chkBox = (CheckBox)e.Row.FindControl("chkBox");
TextBox txtBox = (TextBox)e.Row.FindControl("txtBox");
Button btn=(Button)e.Row.FindControl("chkBox");
btn.Attributes.Add("onclick", "javascript:Validate('" + chkBox + "','" + txtBox + "')");
}
}
