Hi,
I am trying to add an onKeyup event to a textbox during runtime ie OnRowCreated event
My Code behind is
protected
void GridView_RowCreated(Object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblUnitPrice = (Label)e.Row.Cells[2].Controls[1];
TextBox tbQuantity = (TextBox)e.Row.Cells[3].Controls[1];
int s = 0;
if (lblUnitPrice != null)
{
tbQuantity.Attributes.Add(
"onKeyUp", "changeMe('" + lblUnitPrice.ClientID + "','" + tbQuantity.ClientID + "','" + s + "')");
}
}
}
what i want to do is basically pass the ID's of label and textbox to a javascript function "changeMe" .. so it can calculate the total price and display in another total textbox in the footer. my aspx code is:
<
script language="javascript">
function
changeMe(oPrice, oQty, oSubTotal)
{
var Price = document.getElementById(oPrice).innerText;
alert(
"val of oPrice is :" + Price);
var splitPrice = Price.split("$");
alert(
"second split: " + splitPrice[1]);
var fl = parseFloat(splitPrice[1]);
alert(
"val of fl is :" + fl);
var Qty = document.getElementById(oQty).value;
alert(
"val of Qty is :" + Qty);
SubTotal = Number(fl) * Number(Qty);
alert(
"val of SubTotal is :" + SubTotal);
if (document.getElementById("_ctl0_ContentPlaceHolder1_ItemsSummary__ctl4_txtTotal").value == "")
{
alert(
"Subtotal is nothing");
//document.getElementById(oSubTotal).value = SubTotal;
document.getElementById(
"_ctl0_ContentPlaceHolder1_ItemsSummary__ctl4_txtTotal").value = SubTotal;
}
else
{
alert(
"Subtotal is something :" + Subtotal);
document.getElementById(
"_ctl0_ContentPlaceHolder1_ItemsSummary__ctl4_txtTotal").value = Number(document.getElementById("_ctl0_ContentPlaceHolder1_ItemsSummary__ctl4_txtTotal").value) + Number(SubTotal);
//document.getElementById(oSubTotal).value = Number(document.getElementById(oSubTotal).value) + Number(SubTotal);
alert(
"new val of subtotal :" + document.getElementById("_ctl0_ContentPlaceHolder1_ItemsSummary__ctl4_txtTotal").value);
}
}
</script>

Umar
