I have some HtmlSelect (a'la asp.net's DropDownList) with ID's like Select1, Select2, ..., Select13. I create the static List of items:
for (int i = 0; i < tab.Length; i++)
_listItems[i] = (new ListItem { Text = tab[0, i], Value = tab[1, i], Selected=false });
then I assign that list for each HtmlSelect control & assign a new SelectedIndex property:
var HtmlSelectControl = ((HtmlSelect)this.FindControl(String.Format("Select{0}", controlNumber)));
HtmlSelectControl.Items.AddRange(_listItems);
HtmlSelectControl.SelectedIndex = controlNumber - 1;
The problem is, when I set the SelectedIndex property of the Select2 control (e.g. =1), the Select1 control has the same SelectedIndex property (which has that index =0). Why ?
by doing this can i call selectedindex change of dropdown on pageload:
dropdownlist_selectedindex(nothing,nothing)
if yes, then what is the situations wherein i will require to do such a thing.
if not, then how do i do it?
I have one ListBox which has three Items in it. And also has one GridView and One Button.
I want to move the selected items in the listbox to the GridView when the Button is clicked.
Now the problem is, if I selects the third item in the listbox and clicks the button, It always moves the first item in the ListBox to the GridView.
How to solve this?
<asp:ListBox ID="lbDrawing" runat="server" AutoPostBack="false" Height="260px" TabIndex="12" Width="150px"></asp:ListBox>
In the Button click event, I select the item by the following C# code,
string itemsname = lbDrawing.Items[lbDrawing.SelectedIndex].Text;
I fill the ListBox based the DropDownList SelectedIndex Changed Event. So I can not bind the ListBox in the Page is not PostBack Block.
how to change my accordion pane's selectedindex and have come up empty handed thus far.
I've tried both with javascript and C#
Javacsript example:
var a = $('<%=AccordionMain.ClientID%>');
a.set_SelectedIndex(index);
C# example:
AccordionMain.SelectedIndex = 2;
Both of the above code excerpts run, but neither visibly change the selected pane. What am I doing wrong?

I'm trying to programmatically set the property of a control on my Form AFTER I've proccessed an update command using the FormView, but it's not working. In my example below, I have a basic FormView with only a TextBox and Label in its EditItemTemplate. The FormView uses an AccessDataSource. The TextBox is bound to the datasource, but the label is not. What I'm trying to do is update the value in the TextBox (as well as its associated data stored in the database), and then change the Text property of the Label. (*Note: that I using the label purely as an example. The point is I can't see to set any control's property after an update).
I initally thought it had something to do with the "Page.IsPostBack", but even after trying to adjust my code for that, its still not working. I've tried change the Text property during the Page.IsPostBack during Page_Load event. I've tried setting the Label's EnabledViewState property to True and to False. I've tried using the FormView's OnItemUpdating and OnItemUpdated events. I've tried using the DataSource's OnUpdating and OnUpdated events.
I don't seem to be able to set the Text property within this custom control. Even though I set the Text property in code-behind, when I refresh the web form, only the default message is shown.

I have multiple .sitemap xml defined with different providers. For one xml file, I want to change the url (append Customerid in the url) by taking the defined url in xml file. I want this to be changed when the page is loaded the first time.
For eg one of my node is
<siteMapNode
url="~/CustDetail.aspx?type=Contact"
title="Contacts"
description="Contacts">
And I want to make it as
<siteMapNode
url="~/CustDetail.aspx?type=Contact&CustID=ABCD"
title="Contacts"
description="Contacts">
I have read many articles online talking about changing node in memory but cant make it work.
I'm trying to use PostBackUrl on my asp.net form (insert mode) to go back to previous page. I'm hoping to use Request.UrlReferrer.AbsoluteURL or similar.The difficulty I have is how to assign value to link button (called InsertButton) property "PostBackURL".
Some examples show simply InsertButton.PostBackUrl = Request.UrlReferrer.AbsoluteURL but it my case it doesn't recognize the control. I'm using VS 2010 with asp.net 4.0

I'm trying to use the menu control for the first time in ASP.NET and everything is fine except for the fact that I can't seem to change the item spacing property. My menu is a horizontal menu where the menu items have come from a sitemap file. I've tried changing the menu item spacing in both the dynamic and state menu item properties but nothing seems to change it. I've also tried changing the item spacing via css but that doesn't work either.

I came to know that we can pass values from one page to another. What I wanted was 'on click of a button on admin.aspx webpage , the button on user.aspx page gets invisible'
After creating the instance and trying to do so, the error occured which said-"due to security the button cannot be accessed on user.aspx from admin.aspx"
Even if all the above what I did was wrong, I request you to suggest me how can I change the property of a button on webform1 from webform2 ( this is the admin.aspx page in which i have logged in) to invisible. And whosoever accesses the webform1 gets the same property (i.e. invisible) untill i click on the button in webform2 that again turns the property of the button in webform1 as visible.
i have a page for search.and there is abutton when user click on it.result get in dataset.

I am trying to create a script that changes its output based on a range of values. Here is what I mean:
I have a MSSQL database with an ASP scripted website that reads it and displays the data in a table. One of the columns in the database is a percentage and I want that column in the web page to have a background colour based on the figure outputted.
So each cell may be a different colour. If the number is between 0 and 30 then red background, 31 to 70 orange etc.
At the moment I have the database output script looking like this:

I have a shooping cart in version 9.0.1.3
I have several products with two variants for each.
I can add any quanity to the first variant and it is calculated into the cart correctly.
When I try to add a number besides one for the second variant it will only show one of the porduct in the cart.
I can change the quanity when it is in the cart. But I need it to work correctly.
The code below is inside an UpdatePanel... is there anything else I am supposed to do to change the color of the output?

I have a custom control that inherits from .NET's CompositeControl class. This control overrides the CreateChildControls in order to build its child controls dynamically. I need the page to post back after a couple different javascript events occur on the client side.
In order to accomplish this, I create two hidden controls on the page so I can set their values with javascript, submit the page, and read the values out on server side. Here's is the code I use to create these two hiddens:

I'm trying to set a property on a custom DropDownList:
<custom:ReferenceDropDownList ... ValidityDate="<%# Application.CreateDate %>" />
Even though I can see that Application.CreateDate has been set in the Page_Load method on the containing UserControl, the code-behind in the DDL never seems to pick it up.
protected override void OnLoad(EventArgs e)
{
// this.ValidityDate is always null
}
This is even the case with ValidityDate="<%# DateTime.Now %>". The property of the DDL is declared like this:
[Category("Data")]
[DefaultValue(null)]
public DateTime? ValidityDate { get; set; }
what is the correct sequence I should be following here. I thought that a DDL would evaluate a cynamic property value like that without too much trouble.
I have added some profile properties to my web.config:
<profile automaticSaveEnabled ="true">
<properties>
<add name="NumVisits" type="System.Int32"/>
<add name="UserName" type="System.String"/>
<add name="Gender" type="bool"/>
<add name="Birthday" type="System.DateTime"/>
</properties>
</profile>
However when I try to access the property in a code behind it does not exist. The following code does not work (says firstname is not a property):
Profile.Gender And In the Asp.net Configuration 'Profile tab ' Is not showing. I have rebuilt the solution. I am using VB.NET(3.5)
I have an automatic property
public int GearCount { get; set; }

Whats wrong here ? Also if i do normal intantiation it works fine.
Tandem t = new Tandem();
Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:
