I am having trouble setting panel visibility
but on change JavaScript returning null reference exception.
JavaScript runtime error: Unable to get property 'setAttribute' of undefined or null reference
I want to make panel TrMarketingDetails visible based on a radio button (RbMarketing) change.
JavaScript
function trVisible(val) {
var selected = $("#" + val.id + " input:radio:checked").val();
if (selected == "1") {
document.getElementById('<%=TrMarketingDetails.ClientID %>').setAttribute("style", "visibility: visible");
document.getElementById('<%= hfdMarket.ClientID %>').value = 'Y';
}
else if (selected == "2") {
document.getElementById('<%=TrMarketingDetails.ClientID %>').setAttribute("style", "visibility: hidden");
}
}

W3C link for style.visibility
document.getElementById("controlid").style.visibility = "hidden"
you just change like
function trVisible(val) {
var selected = $("#" + val.id + " input:radio:checked").val();
if (selected == "1") {
document.getElementById('<%=TrMarketingDetails.ClientID %>').style.visibility = "visible";
document.getElementById('<%= hfdMarket.ClientID %>').value = 'Y';
}
else if (selected == "2") {
document.getElementById('<%=TrMarketingDetails.ClientID %>').style.visibility = "hidden";
}
}
You are already use jquery syntax in your code, then good to do this via jquery syntax like
$('#<%=TrMarketingDetails.ClientID %>').show();
$('#<%=TrMarketingDetails.ClientID %>').hide();

In the below code there is a radiobuttonlist control and Multiline textbox. On button click I would need to check whether textbox query should contain any WHERE clause. If yes then will get executed directly, but if not then should get confirmation box. If clicked on "Ok" then should get proceed but if clicked on "Cancel" then process get terminated there itself.
In my case confirmation box is not popping up and how to get it's value at code behind?
For this I would have followed an article as

I have a UserControl "Day" that is repeated 5 times in another UserControl for 5 weekdays in a week that means each day 1 UserControl. And in this UserControl has RadioButtonList rdlAmountSlot is repeated 4 times with the below data
rdlAmountSlot_0 - Amount1 --- (1 - 100)
rdlAmountSlot_1 - Amount2 --- (100 - 1000)
rdlAmountSlot_2 - Amount3 --- (1000 - 10000)
rdlAmountSlot_3 - Amount4 --- (10000 - 100000)
I used the below code for confirmation from the user
$(document).ready(function(){
$("[id^='rdlAmountSlot_'][type='radio']").change(function () {
var radioBtnId = this.id;
var $this = $(this);
radconfirm('Are you sure you want to select this slot?', function(arg){
if (arg == true) {
$find('<%= FindControl("txtAmount").ClientID %>').set_value("");
}
else {
$this.siblings('input').prop('checked',true);
var rdlAmountSlot = document.getElementById(radioBtnId);
rdlAmountSlot.checked = false;
$this.prop('checked', false);
}
}, 300, 100,"");
});
});
The above code is throwing confirmation box for 5 times. What could be the reason and how to resolve it?
UPDATE
Below is my markup code for each day
<asp:UpdatePanel runat="server" ID="pnlUpdate" UpdateMode="Conditional">
<ContentTemplate>
<asp:Panel ID="pnlDayView" runat="server">
<asp:RadioButtonList ID="rdlAmountSlot" CssClass="radio1" runat="server" ClientIDMode="Static">
</asp:RadioButtonList>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
Below is the markup for 5 days
<table>
<tr>
<td>
<asp:Panel ID="pnlMonday" runat="server" >
<uc1:My ID="MyMonday" runat="server" />
</asp:Panel>
</td>
<td>
<asp:Panel ID="pnlTuesday" runat="server" >

This is the code similar to rdlAmountSlot
<table id="ctl00_ContentPlaceHolder1_MyAvailability_MyAvailabilityMonday_rdlAvailability" class="radio1" border="0" style="color: #004B59; font-size: 11px; font-family: Arial, Sans-serif; text-align: justify">

</tr>
</table>
May be if you try with each it would work.
$(document).ready(function(){
$("[id^='rdlAmountSlot_'][type='radio']").each(function () {
$(this).change(function(){
var radioBtnId = this.id;
var $this = $(this);
radconfirm('Are you sure you want to select this slot?', function(arg){
if (arg == true) {
$find('<%= FindControl("txtAmount").ClientID %>').set_value("");
}
else {
$this.siblings('input').prop('checked',true);
var rdlAmountSlot = document.getElementById(radioBtnId);
rdlAmountSlot.checked = false;
$this.prop('checked', false);
}
}, 300, 100,"");
})
});
});
I need to validate the input so the difference between Date1 and Date2 no more then 30 days.
I'm trying to use custom validation in asp.net, but not sure if in my case it would be the correct choice.
I have the following html:
.
.
.
<tr>
<td>
<asp:Label ID="lblFileDate" runat="server">File Date: from</asp:Label>
</td>
<td>
<asp:TextBox ID="txtDateFrom" runat="server" CssClass="datepicker1"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfvDateFrom" runat="server" ControlToValidate="txtDateFrom" ForeColor="Red" ErrorMessage="Date From is Required" ValidationGroup="vgForm" >*</asp:RequiredFieldValidator>
</td>
<td style="padding-left:40px; text-align:right;">
<asp:Label ID="lblDateTo" runat="server" >to:</asp:Label>
</td>
<td width="165">
<asp:TextBox ID="txtDateTo" runat="server" colspan="2" CssClass="datepicker2"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfvDateTo" runat="server" ControlToValidate="txtDateTo" ForeColor="Red" ErrorMessage="Date To is Required" ValidationGroup="vgForm" >*</asp:RequiredFieldValidator>
<asp:CustomValidator ID="cstDateValidation" runat="server" ErrorMessage="Date difference should not be more then 30 days" ClientValidationFunction="ValidateDateDiff"></asp:CustomValidator>
</td>
</tr>
<tr>
<td style="text-align: right;" colspan="4">
<asp:Button id="btnSearch" Text="Search" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" runat="server"
CausesValidation="true" CommandName="Search" OnCommand="btnSearch_Click" OnClientClick="return ValidateFields()" />
</td>
</tr>
.
.
.
<div id="errorDisplay">
<asp:ValidationSummary ID="vSum" runat="server" ShowSummary="true" ValidationGroup="vgForm"></asp:ValidationSummary>
</div>
This is my javascript:
function ValidateFields() {
var isValid = false;
isValid = Page_ClientValidate('vgForm');
if (!isValid) {
$('#errorDisplay').dialog({
title: "Validation Error",
modal: true,
resizable: false,
width: 250,
buttons: {
Close: function () {
$(this).dialog('close');
}
}
});
return false;
}
return true;
}
function ValidateDateDiff(sender, args) {
var dateFrom = $('#cphBody_Cnt_txtDateFrom').val();
var dateTo = $('#cphBody_Cnt_txtDateTo').val();
var diff = dateFrom - dateTo;
if (diff > 30) {
args.IsValid = false;
}
}
What is the best way to do something like that?

The textbox txtclnum calls the javascript function MoveNext at the bottom of the page (just to make sure everything loads in the right order)(this is taken from the first answer to this question). MoveNext has an alert in it to tell me what tabbables.length is. The alert returns 0 because the CssClass in the .Net controls overwrites the class="tabbable" in the HTML. I've tried
var tabbables = document.getElementsByTagName("*");
which gets me to the correct control, but the focus doesn't stay on that control. How can I keep the focus on the control?
That function takes as its argument a CSS selector, so if you're looking for elements with class "tabbable" you would use document.querySelectorAll(".tabbable")
Since tabbable is a class, you need to put a period in front of it in your queryselector, so it should be:
document.querySelectorAll(".tabbable")
Edit: Just further clarification, the queryselector without the "." would be looking for html tags like <tabbable>. Since that does not exist, the length returned is 0.
The way you're using it, document.querySelectorAll("tabbable") is looking for an element of the tag <tabbable>. Since it looks like you're trying to query by a class, add the period to denote it is such.
document.querySelectorAll(".tabbable")
When you use document.getElementsByClassName("tabbable") it could work, so I could see where you could get confused if you've used that method in the past.
OK, I feel like an idiot. Just for others' future reference, the problem was that 1) there's a Cssclass assigned to those controls, which overrides my tabbable class in the HTML markup; and 2) once I took care of that (see below code), it still wasn't working because (duh) each control had an AutoPostBack=true on it (they used to have server-side code attached to them). Now that AutoPostBack is false, my code works fine. Here it is:
<script type="text/javascript" lang="javascript">
function MoveNext(currentElement, btnID) {
$(document).ready(function () {
var saveButton = document.getElementById(btnID);
saveButton.disabled = false;
var lastTabIndex = 4;
var curIndex = currentElement.tabIndex; //get current elements tab index
if (curIndex == lastTabIndex) { //if we are on the last tabindex, go back to the beginning
curIndex = 0;
}
var tabbables = document.getElementsByTagName("*"); //get all tabbable elements
for (var i = 0; i < tabbables.length; i++) { //loop through each element
if (tabbables[i].tabIndex != null & tabbables[i].tabIndex == (curIndex + 1)) { //check the tabindex to see if it's the element we want
tabbables[i].focus(); //if it's the one we want, focus it and exit the loop
break;
}
}
});
}

prm.add_initializeRequest(InitializeRequest);
prm.add_endRequest(EndRequest);
function InitializeRequest(sender, args) {
$('#nima').css('display', 'block');
}
function EndRequest(sender, args) {
$('#nima').css('display', 'none');
}
where is my mistake?
thanks
