Page Validation not functioning with JavaScript code

I have requiredFieldValidator for a dropdownlist inside a panel. If there is no data selected in the dropdown btnSubmitReport works fine to validate and display *. Once data is selected and btnSubmitReport is clicked to display data it still works fine. Now if you unselect the dropdown and hit btnSubmitReport it does not do validation anymore. This is because first time btnSubmitReport_Click is clicked, it checks to see if Page.IsValid and calls JavaScript code, but subsequent calls are just calling JavaScript code and btnSubmitReport_Click is not being called to see if the page is Valid. Please suggest. Here is the sample code on the aspx page:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="testValidator.aspx.cs"

Here is the code behind:
protected void btnSubmitReport_Click(object sender, EventArgs e)
{
if (Page.IsValid)
{
btnSubmitReport.Attributes["onclick"] = "javascript:SubmitF();";
}
//then do rest of the processing to display grid results
}
and here is Reports.js file:
function ShowF() {
$('#lnkShowFilter').hide();
$('#divFilter').show();
$('#lnkHideFilter').show();
$('#divResult').hide();
$('#MainContent_lblHeader').text("Reporting Filter");
}
function HideF() {
$('#lnkShowFilter').show();
$('#divFilter').hide();
$('#lnkHideFilter').hide();
$('#divResult').show();
$('#').show();
$('#MainContent_lblHeader').text("Report Result");
}
function SubmitF() {
// alert("SubmitF");
$('#lnkShowFilter').show();
$('#divFilter').hide();
$('#lnkHideFilter').hide();
$('#divResult').show();
$('#MainContent_lblHeader').text("Report Result");
}

well, I was able to solve the issue by using client-side validation. So I created a function
<script type="text/javascript">
function ValidateAndShowPopup() {
if (Page_ClientValidate('grpSubmit')) {
SubmitF();
}
}
And added both OnclientClick and OnClick to the submit button
<asp:Button ID="btnSubmitReport" runat="server" Text="Submit" OnClick="btnSubmitReport_Click" ValidationGroup="grpSubmit" OnClientClick="ValidateAndShowPopup()" CssClass="btn" />

UpdatePanel issue when using javascript only controls

Included below is my markup for a page I have using a FineUploader control. I've abridged the code to only include the important parts. This page is two parts that both reside in an UpdatePanel. The first part is a simple table that contains rows of data, the last column of each row is a asp:LinkButton. The second part is a nested UpdatePanel that contains a div in which the FineUploader control is rendered when the page is first loaded (because the FineUploader control is strictly javascript and does not further exist in the code-behind). Also, when the LinkButton is pressed this.Page.IsPostBack is false.
The problem is that any time a LinkButton in the first part of the page is pressed, the FineUploader control simply disappears. I cannot get the code to re-render from the code-behind (with things like ClientScript.RegisterStartupScript/RegisterClientScriptBlock). I've also tried various setups with wrapping Part 1 with an UpdatePanel but still it wipes out my FineUploader control. I'm thinking I'm using update panels incorrectly, but am not sure (ASP.NET is not usually what I work in).
As an added detail, if I click a button inside the Part 2 nested UpdatePanel, my FineUploader control magically reappears.

How can I make my FineUploader control stay visible?
EDIT 1:
Considering this might be a page life cycle issue, I attempted a manual render of the control by adding the following:
protected void Page_Init(object sender, EventArgs e)
{
string script = "<script type=\"text/javascript\">" +
" alert('oh hey');" +
" $(document).ready(function () {" +
" var uploader = new qq.FineUploader({" +
" element: $('#fine-uploader')[0]," +
" request: {" +
" endpoint: 'AccountSetup.aspx'" +
" }," +
" autoUpload: true," +
" multiple: false," +
" text: {" +
" uploadButton: '<asp:Button ID=\"fineUploadButton\" runat=\"server\" CssClass=\"button\" style=\"width:6;5\" Text=\"Browse\" />'" +
" }," +
" validation: {" +
" allowedExtensions: ['mp3', 'wav']" +
" }" +
" });" +
" });" +
"</script>";
ClientScript.RegisterClientScriptBlock(this.GetType(), "HideOnPostback", script, false);
System.Diagnostics.Debug.WriteLine("Page_Init() run");
}
The result was that if I click the "Edit" LinkButton in Part 1, I see "Page_Init() run" in debug output, but the control still goes away and the "oh hey" js alert is never displayed. However, if I click the other button in Part 2, I see "Page_Init() run" in the debug output, I see the "oh hey" alert and the FineUploader button remains visible.

I believe you are experiencing this issue because you are loading the FineUploader control too late in the page lifecycle for it to properly load the ViewState. Clicking the button is triggering a postback which restarts the lifecycle for the page. ViewState is loaded before Page_Load() so try to add the control to the page during Page_Init() instead so that the ViewState can be loaded.

how do i use jQuery get the parent radcombobox control object from the checkbox click event?

I have a radcombobox with checkboxes turned on. I wrote a jQuery script to add a click event to all of them. What I need to move on to the next step is a way to get the combobox in which that item/checkbox resides. Something like this:
$(."comboBoxTag.find(":checkbox").click(
function(){
var cboObject = $(this).???
});
this way I can do things like access the telerik api methods like cboObject.get_items();
I have the control tagged with a CSS class called "AssigneeTag", but doing a .closest(".AssigneeTag") isn't returning anything...
any ideas?

This is a listview with another listview nested in the itemtemplate. in the itemtemplate of the inner list resides the controls. The combobox im referring to is named cboAssignTo. It is a Telerik combobox, so it does not work like a traditionial DropDown menu, which I think is what is really complicating this on top of the fact that the comboboxes are dynamically generated. I was able to do things like $(this).closest(".rcbTag") to get the values of the other combobox called cboStatus, but this other combobox involves a bit more as it has checkboxes.
EDIT:
Here is a watered down easier to read version of what stage I'm at. This is the HTML generated by a single instance of this combobox:
<div id="lsvTest" class="RadComboBox RadComboBox_Default RcbTag" style="width:160px;">
<table summary="combobox" style="border-width:0;border-collapse:collapse;table-layout:fixed;width:100%">
<tr class="rcbReadOnly">
<td style="margin-top:-1px;margin-bottom:-1px;width:100%;" class="rcbInputCell rcbInputCellLeft">
<input name="lsvTest" type="text" class="rcbInput" id="lsvTest_Input" value="" style="display: block;" readonly="readonly" />
</td>
<td style="margin-top:-1px;margin-bottom:-1px;" class="rcbArrowCell rcbArrowCellRight">
<a id="lsvTest_Arrow" style="overflow: hidden;display: block;position: relative;outline: none;">select</a>
</td>
</tr>
</table>
<!-- 2012.1.215.40 -->
<div class="rcbSlide" style="z-index:6000;">
<div id="lsvTest_DropDown" class="RadComboBoxDropDown RadComboBoxDropDown_Default " style="float:left;display:none;">
<div class="rcbScroll rcbWidth" style="width:100%;">
<ul class="rcbList" style="list-style:none;margin:0;padding:0;zoom:1;">
<li class="rcbItem "><input type="checkbox" class="rcbCheckBox" />One</li>
<li class="rcbItem "><input type="checkbox" class="rcbCheckBox" />Two</li>
<li class="rcbItem "><input type="checkbox" class="rcbCheckBox" />Three</li>
</ul>
</div>
</div>
</div>
<input id="lsvTest_ClientState" name="lsvTest_ClientState" type="hidden" />
</div>
Just looking at this, I feel like clicking a checkbox and then using $(this).closest(".RcbTag") should traverse all the way to the top and grab the outer div, but it is not.

As with the other question, I think your life will be easier if you stick with the Telerik-sanctioned methods. Here is how you could do it using them:
<script language="javascript" type="text/javascript">
function OnClientItemChecked(sender, eventArgs) {
var item = eventArgs.get_item();
var combo = item.get_comboBox(); // Now you have a reference to the parent ComboBox
}
</script>
And the RadComboBox itself:
<telerik:RadComboBox ID="RadComboBox1" runat="server"
OnClientItemChecked="OnClientItemChecked" CheckBoxes="true">
</telerik:RadComboBox>

I solved similar issues using jQuery parent() calls, did you try this?

Why scrolling "Up" after text changed event? (Weird action)

Q:
I have a gridview which contains text box as a template field.The grid view exists in an update panel . My problem is:
When the text changed event has fired , feel like a jumpof the browser similar to the behavior of (post back).but it isn't a post back. I don't know why this strange behavior happened.

calc();
int index = ((System.Web.UI.WebControls.GridViewRow)(((RadTextBox)sender).Parent.NamingContainer)).DataItemIndex;
//int index = int.Parse(((RadTextBox)sender).Attributes["hideData"]);
((RadTextBox)gv_Evaluation.Rows[index + 1].Cells[3].FindControl("txt_evaluateWeights")).Focus();
}
still the same problem!!
EDIT2:
protected void gv_Evaluation_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblSerial = (Label)e.Row.FindControl("lblSerial");
lblSerial.Text = ((gv_Evaluation.PageIndex * gv_Evaluation.PageSize) + e.Row.RowIndex + 1).ToString();
RadTextBox txt = e.Row.FindControl("txt_evaluateWeights") as RadTextBox;
ScriptManager.GetCurrent(this).RegisterAsyncPostBackControl(txt);
}
}
still the same problem!!
EDIT3:
I knew the problem , but i don't know how to fix it:
the problem is as a result of this line:
((RadTextBox)gv_Evaluation.Rows[index + 1].Cells[3].FindControl("txt_evaluateWeights")).Focus();
but i need this line of code. How to prevent the Focus() method from making a jump to the top of the page.

Is the # symbol necessary here (line 2 below):
<telerik:RadTextBox ID="txt_evaluateWeights" runat="server" AutoPostBack="True" OnTextChanged="txt_evaluateWeights_TextChanged" hideData='
<%#((GridViewRow)Container).RowIndex%>'>
If you use a blank # aka html name anchor in a link it makes the page jump to the top.
ex. Top
would make a link that when clicked on would jump you to the top of the page. Your OnTextChange event looks like it contains a # that might be causing your issue.

Are you sure this is not a Postback? You should define your triggers.
I believe this might be a similar problem, with a solution:

ScriptManager.RegisterClientScriptBlock doesnot open window in specified sizes

Hello everyone iam trying to open a aspx page in a dialog box window from asp button click event but even after specifying the dialog height and dialog width i want i could see dialog window opening in a default size.It seems like the height and width parameters i am passing are ignored.
Here is the Server Side Code:
ScriptManager.RegisterClientScriptBlock(this.Page, this.Page.GetType(),Guid.NewGuid().ToString(), "try { showMessageRulesDialog('MessageRuleCenterFrame.htm', true); }catch(e){alert(e);}", true);
JavaScript Code:
function showMessageRulesDialog(dialogName, refresh)
{
try {
var WinSettings = "wcenter:yes;resizable:no;onscroll:off;dialogHeight:700px;dialogWidth:610px;";
var ret = window.showModalDialog("../Dialogs/" + dialogName,"", WinSettings);
if (refresh) {
window.location = window.location;
}
}
catch (e)
{ alert("ShowDialog Error: " + e); }

I tried your code and it seems it works fine. My guess for why it is not working as expected could be because of the browser version.
Check if you get the required behavior if you remove the Doctype declaration (the top most line in the page).
