I want to create an unorderd list dynamically from my codebehind (c#) and im having a few problems, heres what I need to create
[Code]....
Ive tried setting runat=server but how do i add the list items ?
I have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load
I have the following Students class:

I need the 1 since it's a foreign key in another table. For the life of me, I can't get this to work like this.
Is it possible to set tab index value for list items of ASP.Net RadioButtonList control.
View 1 RepliesI'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
<asp:DropDownList ID="ddlFilter" runat="server" >
<asp:PlaceHolder ID="ListItemPlaceholder" runat="server"/>
</asp:DropDownList>
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
<mytag:MyControl Mode="DropDown" runat="server">
<ListItemTemplate>
<asp:ListItem Text="C" Value="c"></asp:ListItem>
<asp:ListItem Text="E" Value="e"></asp:ListItem>
<asp:ListItem Text="B" Value="b"></asp:ListItem>
</ListItemTemplate>
</myTag:MyControl>
I know I can do this by dynamically adding the ListItems in the page code behind, but I'd like to avoid that if possible.
I am getting this error yet I know it to be untrue.This is the code:
ddlPartnerOrganisation.DataSource = agency.AgencyGetListOfEYDN();
string temp = ddlPartnerOrganisation.SelectedValue.ToString();
ddlPartnerOrganisation.DataValueField = "AgencyID"
;
ddlPartnerOrganisation.DataTextField = "AgencyName"
;
ddlPartnerOrganisation.DataBind();
Is it possible to select values from a List, where the items contain in a different list aswell?for example;

What I need are all the items from the first list "Items", where the string contains something from the second list "List".So I need something which returns the first 3 items (which contain the term "Item") from the first list.
HOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.
I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:
<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>
On the ASP.NET page, in the Page_Load I would code somethign like this:
[URL]
Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.
If the client did have runat=server the designer.cs would have somethign liek this:
System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;
With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".
do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.
When I use an anchor tag on an aspx page as below,
<a href="~/pages/page.aspx?id=<%= ServervariableName %>"> test </a>
it will get the variable value correctly assigned to id but it won't route the page correctly as the ~ will not be evaluated without the runat="server" attribute on the 'a' tag. But once I add the runat server attribute, it does not evaluate the servervariable name anymore.. how this works or what I should do to take care of both?
The AutoPostBack doesn't seem to work. Anything I am leaving out?

Its simple if I have an ASP.net page with an ASP.net linkbutton / hyperlink and I obtain a value from say a SQL Database and I store it in the label...
For example:
this.myLabel.Text = someValueReturnedFromADatabase
This is simple because it goes right to the code behind page and set the text value to the value returned from my database (aside from going into more details with data access layer, etc).
What I was wondering is what if I dont want to use an ASP.net linkbutton and I simply want to use an HTML link button (as I need to call the jquery fade function). How would I set the value someValueReturnedFromADatabase to a control that is not runat=server?
i'm trying make some stuffs in jQuery using asp.net. but the id from runat="server" is not the same as the id used in html.
i'm used to use this to get the id from this situation:
$("#<%=txtTest.ClientID%>").val();
but in this case. it does not work, and i'm clueless why.

View 4 RepliesI have created a new Web project (.Net 3.5) and I've removed the original Default page in favour of creating a Master page and then recreating a Default with Master page. All worked lovely. Now, when I add my controls inside of the ContentPlaceHolder on the Default page, I get compiler errors when I try to access the controls from the CodeFile:
Error 4 '_Default' does not contain a definition for 'FirstName' and no extension method 'FirstName' accepting a first argument of type '_Default' could be found (are you missing a using directive or an assembly reference?)
My declaration of the control:
<asp:TextBox runat="server" ID="FirstName" />
EDIT
Page declaration:
<%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.Master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
Code-behind:string firstname = FirstName.Text;
I have a GridView with a load of data in, there is an ID associated to the data that I would not like to be visible to the users. All worked fine when all the cells were visible, but as soon as I change the ID DataBound column to false, when I try to access the item in code I get "" instead of it's actual value (that worked perfectly when it was visible).

I've got the following in my .aspx:
<input type="image" src="<%=PayPalButtonImage %>" onserverclick="RedirectToPayPal" runat="server" />
In the code-behind I've got this property:

{
get { return PayPalExpressCheckoutButtonUrl;}
}
protected void RedirectToPayPal()
{
}
why can't it see this property or the server method RedirectToPayPal? I get a runtime error of :

It seems to do nothing. I checked this by switching the false and true.

How to access to an HTML control runat server from JavaScript

<input id="Text2" type="text" /></div>

<div style="text-align: left;padding-top:10px">

<input id="Button1" runat="server" type="button" value="Submit" /></div>
</div>
I have this problem - I'm working on an ASP.NET AJAX-application on a server without .net 3.5 which means I can't use ListView (BOO!).
I decided to simply do the ugly way of making a table and giving the tbody an ID and a runat server tag, and put HtmlControls inside from the codebehind (btw - this is a usercontrol, in case it makes a difference).
This all works fine - until the page does a partial postback - and all the elements disappear, since the tag is runat server I assume it requires to be repopulated in the page load.
Is there no way to actually persist the data on partial postback? And only have the content of the control change when I say so in the back end?
I guess I could save the content in a session object upon populating the control, and just repopulate in the Page_Load with the session object - but I was hoping there was a better way to do this?
