asp.net - text boxes lose values entered on tab switch

I have ajax telerik tabs in my code and when I switch the tabs my controls loses whatever I have typed.
I tried "enableViewState" to true. It didn't work either.
What I want is the controls to retain values entered on tab switch

Can someone point out the issue pls ?

Your tabs have NavigateUrl property set, which means they render as links, which means they redirect, they do not use ajax.
That's why the values are not persisted.

Page load first time:Page index in gridView not working

I have two gridView: grvHeadline and gdvNotification, gdvNotification is load data by selected item of grvHeadline .
When page load: data of gdvNotification is load by first item of grvHeadline.
My problem is:
The page load is first: if gdvNotification has paging (1,2,3,...), when i click paging in gdvNotification, it not run. Page is reload but page index is 0.
When i select other item in grvHeadline and reselect first item, then click paging in gdvNotification, it run, page index was changed.
I was debug: When the page is load first time: I click to page index in gdvNotification then pageload() was called with IsPostBack=True, but not call to event gdvNotification_PageIndexChanging of gdvNotification.
Here is my code:
protected void gdvNotification_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
logger.Debug("Gridview Headline page index changing .");
gdvNotification.PageIndex = e.NewPageIndex;
HeadlineSelected(hdfNotificationIdSelected.Value, e.NewPageIndex);
//gdvNotification.DataBind();
lbPageIndex.Text = (e.NewPageIndex + 1).ToString(CultureInfo.InvariantCulture);
}
And
private void HeadlineSelected(string notificationIdSelected, int index)
{
logger.Debug("Head line selected");
GetDataFromSessionAndCache();
IList<InformationEntity> infoNotificationList = new List<InformationEntity>();
if (string.IsNullOrEmpty(notificationIdSelected))
{
//Clear
IList<InformationEntity> data = new List<InformationEntity>()
{
new InformationEntity()
{
AuthorName = string.Empty,
Contents = string.Empty,
BulletinDateFrom = null,
BulletinDateTo = null,
Id = string.Empty,
Subject = string.Empty,
}
};
gdvNotification.DataSource = data;
gdvNotification.DataBind();
pnPageIndex.Visible = false;
btnEditNotification.Enabled = false;
}
else
{
infoNotificationList = MasterDataHelper.GetInformationByHighOrderId(notificationIdSelected);
logger.Debug("Notification list not null");
if (infoNotificationList != null)
{
if (infoNotificationList.Count == 0)
{
pnPageIndex.Visible = false;
hdfNotificationId.Value = string.Empty;
btnEditNotification.Enabled = false;
}
else
{
if (infoNotificationList.Count == 1)
{
fakepanel.Visible = true;
}
else
{
fakepanel.Visible = false;
}
if (base.IsPermission(PERMISSION_INFORMATION_FOLLOWUP))
{
btnEditNotification.Enabled = true;
}
pnPageIndex.Visible = true;
gdvNotification.PageIndex = index;
hdfNotificationId.Value = infoNotificationList[index].Id;
gdvNotification.DataSource = infoNotificationList;
gdvNotification.DataBind();
}
logger.Debug("Set value for label total page");
lblTotalPage.Text = gdvNotification.PageCount.ToString(CultureInfo.InvariantCulture);
lbPageIndex.Text = gdvNotification.PageCount == 0
? gdvNotification.PageCount.ToString(CultureInfo.InvariantCulture)
: (gdvNotification.PageIndex + 1).ToString(CultureInfo.InvariantCulture);
lbTotal.Text = infoNotificationList.Count().ToString(CultureInfo.InvariantCulture);
}
}
}

Can somebody tell me what's happening?
(p/s: i'm trying to learning English, if you don't understand, please tell me.)

Prevent Modal Dialog from closing on submit when client side validation fails

I have a Submit button on the page, which upon being clicked, shows a modal popup window. This modal popup window contains a checkbox that must be checked before the OK button of the modal can be clicked:
<script language="javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script language="javascript" type="text/javascript">
function cvcbCertify_ClientValidate(sender, e) {
var elem = document.getElementById('<%= cbCertify.ClientID %>');
if (elem.checked)
e.IsValid = true;
else {
$('.pnlConfirm').show(); //not working?
e.IsValid = false;
}
}
<ajaxToolkit:ConfirmButtonExtender ID="cbeResponseReferralSignOff" runat="server"
TargetControlID="ResponseLocalSignOff" DisplayModalPopupID="popConfirm">
</ajaxToolkit:ConfirmButtonExtender>
<ajaxToolkit:ModalPopupExtender runat="server" ID="popConfirm" TargetControlID="ResponseLocalSignOff"
BackgroundCssClass="modalBackground" DropShadow="true" OkControlID="btnConfirmCertify"
CancelControlID="btnCancel" PopupControlID="pnlConfirm">
</ajaxToolkit:ModalPopupExtender>
<asp:Panel runat="server" ID="pnlConfirm" Style="display: none; background-color: White;
border: solid 1px Gray; width: 90%; height: 100%; padding: 10px" CssClass="pnlConfirm">
<asp:Panel runat="server" ID="pnlConfirm" Style="display: none; background-color: White;
border: solid 1px Gray; width: 90%; height: 100%; padding: 10px" CssClass="pnlConfirm">
popup text here
<asp:CheckBox runat="server" ID="cbCertify" Text="I Certify" CssClass="cbCertify">
</asp:CheckBox>
<br />
<asp:CustomValidator runat="server" ID="cvcbCertify" ClientValidationFunction="cvcbCertify_ClientValidate">Required.</asp:CustomValidator>
<br />
<div style="text-align: center">
<asp:Button runat="server" ID="btnConfirmCertify" Text="OK" />
<asp:Button runat="server" ID="btnCancel" Text="Cancel" />
</div>
</asp:Panel>
The problem is the modal window closes when validation fails. How do I prevent this window from closing or repoppen this window?

The only way to do this is by using an UpdatePanel. Additionally this will allow you to use AsyncPostBackTrigger with a Conditional UpdateMode with control events as well.
For example
<asp:Panel runat="server" ID="pnlConfirm" Style="display: none; background-color: White;
border: solid 1px Gray; width: 90%; height: 100%; padding: 10px" CssClass="pnlConfirm">
<asp:UpdatePanel ID="upItem" runat="server">
<ContentTemplate>
popup text here
<asp:CheckBox runat="server" ID="cbCertify" Text="I Certify" CssClass="cbCertify">
</asp:CheckBox>
<br />
<asp:CustomValidator runat="server" ID="cvcbCertify" ClientValidationFunction="cvcbCertify_ClientValidate">Required.</asp:CustomValidator>
<br />
<div style="text-align: center">
<asp:Button runat="server" ID="btnConfirmCertify" Text="OK" />
<asp:Button runat="server" ID="btnCancel" Text="Cancel" />
</div>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>

Solution was to get rid of the ConfirmButtonExtender and make my own validation:
function Validate_Click() {
//using asp.net checkbox so have to go this route to get bool
var checked = $('#<%= cbCertify.ClientID %>').is(':checked');
if (checked) {
$('.lblConfirmCertifyError').hide();
return true;
}
else {
$('.lblConfirmCertifyError').show();
return false;
}
}
<asp:Panel runat="server" ID="pnlConfirm" Style="display: none; background-color: White;
border: solid 1px Gray; width: 90%; height: 100%; padding: 10px">
popup text here
<asp:CheckBox runat="server" ID="cbCertify" Text="I Certify" CssClass="cbCertify">
</asp:CheckBox>
<br />
<asp:Label runat="server" ID="lblConfirmCertifyError" Text="Required." ForeColor="Red"
Style="display: none" CssClass="lblConfirmCertifyError"></asp:Label>
<br />
<div style="text-align: center">
<asp:Button runat="server" ID="btnConfirmCertify" Text="OK" CssClass="btnConfirmCertify" OnClientClick="return Validate_Click()" />
<asp:Button runat="server" ID="btnCancel" Text="Cancel" />
<asp:Button runat="server" ID="btnDummy" Text="" Style="display: none" />
</div>
</asp:Panel>

DataSource And Code Behind

how can i use object of data source that declared in aspx files in code behind ?
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetEntryByID"
TypeName="Entry">
<SelectParameters>
<asp:QueryStringParameter DbType="Guid" Name="id" QueryStringField="ID" />
</SelectParameters>
</asp:ObjectDataSource>
my data source has an object named "ID" i am using Eval("ID") in asp file , how can i get it in code behind without calling select method and using that data source ?
more code :
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1" BorderStyle="None">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<p style="vertical-align: middle; margin: 8px; background-color: #af9b9b; width: 475px;
line-height: 30px; padding-left: 20px; padding-right: 20px;">
<span style="float: left;">View Count :
<%# Eval("View") %>
</span>
<asp:HyperLink ID="HyperLink2" NavigateUrl='<%# Eval("ID","~/ShowStory.aspx?ID={0}") %>'
runat="server"><%# Eval("Title") %></asp:HyperLink></p>
<p style="padding: 10px; padding-top: 0;">
<%# Eval("Text") %></p>
<p style="vertical-align: middle; margin: 8px; background-color: #af9b9b; width: 475px;
line-height: 30px; padding-left: 20px; padding-right: 20px;">
Author : <asp:Label ID="lblUser" runat="server" Visible=false Text=""><%# Eval("UserID") %></asp:Label><asp:Label
ID="lblUser2" runat="server" Text="Label"></asp:Label></p>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
now i want to use membership.GetUser("ID").UserName to get user name via user provider key . and show it in lblUser how ?

membership.GetUser(ObjectDataSource1.ID).UserName would get you the user name of the user matching the ID property, if I'm understanding what you're asking.
To assign it to the asp:Label object would simply be
lblUser.Text = membership.GetUser(ObjectDataSource1.ID).UserName

binded value for a control outside a repeater

Just for curiosity can i give a control that is outside a repeater a binneded value
for example :
<asp:Repeater ID="topicRepeater" runat="server">
<ItemTemplate>
<table border="0" id="bodyTable" runat="server" style="width: 100%; height: 100%;">
<tr>
<td align="left" valign="top" style="padding-top: 6px; padding-right: 30px; padding-left: 5px; width: 50px;">
<img src='App_Themes/WebPortalTheme/images/ProfilePicSmall/<%# Eval("ProPic") %>'
style="width: 50px; height: 50px;" />
<div runat="server" id="username" style="padding-left: 8px; color: #002D79;">
<%# Eval("UserName") %></div>
</td>
</tr>
</table>
</ItemTemplate>
</asp:Repeater>
<telerik:RadTextBox ID="EditedReplyTxt" Text='<%# Eval("msg_text")%>' runat="server" Width="300px" TextMode="MultiLine" Height="100px"></telerik:RadTextBox>

Yes you can, read this example
