hello
i need to put validation on dropdown inside gridview ...tyhe validation should check on button click outside the grid
i already use the below code but it doesn't work for a single drop down
<script type="text/javascript">
function validate() {
var flag = true;
var dropdowns = new Array(); //Create array to hold all the dropdown lists.
var gridview = document.getElementById('<%=Grid_acnthead_pstin.ClientID%>'); //GridView1 is the id of ur gridview.
dropdowns = gridview.getElementsByTagName('select'); //Get all dropdown lists contained in GridView1.
for (var i = 0; i < dropdowns.length; i++) {
if (dropdowns.item(i).className == "ddl_budgetgroup" && dropdowns.item(i).value == 'BudgetGroup') //If dropdown has no selected value
// if (dropdowns.item(i).value == 'BudgetGroup') //If dropdown has no selected value
{
flag = false;
break; //break the loop as there is no need to check further.
}
}
if (!flag) {
alert('Please select value in each dropdown');
}
return flag;
}
</script> actually mry my gridview has 4 column and all the four column contains dropdown.. and i have to put validation for all the 4 dropdowns..
