string pattern = "-";
string[] substrings = Regex.Split(nums, pattern);
arraylength = substrings.Length;
I am having an aspnet panel in my aspx file.There is an ultraweb tab placed inside this.also I am having a button outside this panel.Within the tab I have a textbox whose readonly property is
set to "true".Whenever I click the button a javascript function is called .On clicking 'OK' in the popup ,the textbox values are lost.Is there a way to retain these values?
I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

View 2 RepliesRight now I have an asp:Wizard with 3 Steps.
Create User
Form to Email
Summary of Fields
When the finish button is clicked on the third step I would like to Create the user and send the form. I have the logic for this written but the only problem I have is the when the next button is pressed on a wizard, a PostBack occurs and my password field:
<asp:TextBox ID="txtPassword" TextMode="Password" Width="70%" runat="server" />
Does not retain its value.
I have a MasterPage and a ContentPage. On the ContentPage I Similated a TabControl by using a Menu and an IFrame. When the menu item is seleceted it loads in the appropriate WebPage into the IFrame. Now... on one of the WebPages I am creating dynamic controls on Page_Load. But when I refresh or switch menu (Simulated TabControl) back and forth, then I lose my controls and values.
View 4 RepliesWe currently have a page with several user controls (8 of them) and when a control that is contained in an updatepanel initiates a postback the focus is not retained. In some cases, it looks like the focus is sent to the top of the page, and in other cases the focus looks like it is sent to the control with the TabIndex=1.
I have tried 3 different solutions and they all end up with the same result.
The first two were from article:
[URL]
Solution 1: At the end of the server event executed in postback, add:
[Code]....
The article says both of those solutions worked, but for us, neither of them did.[Code]....
ASPX.CS
[Code]....

In all 3 scenarios the control we want to have the focus gets the focus for a split second and then the focus is cleared (set to the top of page, or TabIndex=1).

In web config file I have add key values specified.
In the formview I have labels on edit , item and insert mode that I want to display all the time by getting those values from web config. I'm able to do that with no problem but when I change the modes between edit to insert or item view, I lose those label values until I hit the "select" twice from the Gridview, those values re-appear. Below is the snippet of the code. What do I need to do to retain the category values all the time?

This is a problem I'm facing in a webapp I'm currently working on. So instead of cluttering the question with unrelated code, I recreated the problem in an isolated, simplified webapp that only demonstrates this issue.
I have a web user control with just this as its content:
<% if (ShowAlertScript)
{ %>
<script type="text/javascript">
function AlertMe()
{
alert('Hello World!');
}
</script>
<% } %>
<input type="button" onclick="AlertMe()" value="Say Hello" />
And its codebehind has nothing more than the boolean definition of ShowAlertScript. This represents a control I have in the big webapp that has two modes: input mode, and display mode. When in input mode, it has a large javascript block that is only useful then; it does some cool stuff to help the user input the info.The way this control is laid out in the big picture is as follows:
<asp:ScriptManager runat="server" />
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:MultiView ActiveViewIndex="0" runat="server" ID="mvw">
<asp:View runat="server">
<asp:Button runat="server" ID="btnSwitch"
OnClick="btnSwitch_Click" Text="Switch" />
</asp:View>
<asp:View runat="server">
<uc:MyInputControl runat="server" ID="micInput" ShowAlertScript="true" />
</asp:View>
</asp:MultiView>
</ContentTemplate>
</asp:UpdatePanel>
When you click btnSwitch, it simply switches to the second view with the user control. Notice how I have the ShowAlertScript already initialized to true. The potential output is that since I'm "showing the alert script" within the user control, the AlertMe() function will execute when you click the input-button element, because it's written out according to the inline if statement.
If you run this code I gave you so far as is, it will not work. The browser will say it can't see the AlertMe() function; it's undefined as far as it knows. But if you take out the UpdatePanel (or disable the ScriptManager's partial rendering), it will work just fine on a full postback when you click btnSwitch.
I want it to work on a partial postback, because this whole thing is a small piece compared to the rest of the page, and I don't want to do a full postback every time they switch views. Apparently, the ScriptManager doesn't even bother re-rendering the ascx file for possible changes. Either the ScriptManager is not smart enough, or there is an option I'm missing to let it render the <script> so I can invoke its methods on the client side. A potential answer someone might suggest is "why don't you take out the javascript, put it in its own .js file, and have the page reference it so it's available to the control?"
That won't really work with me, because the script block does some initialization and modification that pertain to that single control instance, not to all others on the page.
In turn, you might also be concerned that if I have more than one instance of the control, I end up with copies of the same script. Not really; there will only be ONE input mode of this control in a page at any given time, it's just that I have those two modes in two separate views and I let the user switch between them.
I have the example working but I added a Select Command to the Detail grid for the purpose of selecting a detail record which will redirect to another page. The problem is that when the Select command is clicked the expanded detail grid collapses as if I had clicked the minus. The page and codebehind are:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Search1.aspx.vb" Inherits="iDCA.Search1" %>

The graphic designer of a project I'm building a web site for chose jquery.tools [URL] for a tabs tool in the site. Unfortunately it seems that the tool doesn't behave properly on a postback in IE7 or IE8 (it does behave properly in FireFox, Chrome and Safari). Does anyone have experience using the jquery.tools with asp.net? and know how to retain the tab index on a postback? I've tried a lot of things and can't get it to work. The code i'm using now is as follows:
$("ul.tabsScenario").tabs("div.panes > div");
var tabIndex = $('#ctl00_ContentPlaceHolder1_EnInDeToekomst1_HiddenFieldTabIndex').val();
$("ul.tabsScenario").tabs('select', tabIndex);
where the tab index is stored in a hidden field (HiddenFieldTabIndex). The above code works fine in Firefox, Chrome and Safari, but not in IE7 or IE8. I am using a ScriptManager and UpdatePanels, but in an extremely simple website example I can't even get the jquery.tools tabs tool to work. There are some unanswered posts on the Jquery.Tools forum concerning this topic, but yeah, that doesn't help much. I've already determined that the jquery.ui tabs tool works well after a postback but that would cost a lot of refactoring in our project as far as html and css goes. I'd like to avoid that.
Question:-
Page is a typical search page with few filters on it. When search for records based on filters, it shows result in Gridview. From grid view records, user can click on any record to see the details which takes the focus on new page. Its working fine so far.Now when user comes back from details page to search page. I am loosing selected filters values and no result in grid view.How can i display selected filters and its results in gridview when user is coming back on search page? Any example etc.?
I've got a couple pages in my web app that are used by external applications. They will link to the pages, and pass in various querystring values to allow my app to do the searching and return the results in the page. The problem is, if the user is not yet logged into the web app, they are sent to the login page, and the ReturnURL is truncated to include only the first QueryString value. I lose the rest of the values. So far I haven't figured out a solution to this. Here's a quick example:
The external application links the user to:
[URL]
If the user is not logged in they are sent to the login page, and the current URL looks like this:
