Setting Values to dropdown in Repeater Dynamically


Ok So I have a Dropdown in a repeater, which currently has a drop down linking to a single datasource which just 10 items in it..so all the drop downs will have 1-10 as options.

Now I need to change this since each item in the repeater (i.e products) could have a different quantity.

This is what I currently have

<asp:Repeater ID="rptEventsList"  DataSourceID="srcServicesList" runat="server" >
        <input type="hidden" name="hidden<%# Eval("displayOrder").ToString()%>" value="<%# Eval("itemCode").ToString()%>" />

Problem setting endpoint address URL dynamically at runtime in client


I have a WCF web service and clients running on separate windows server 2003 machines. I'm using windows integrated authentication to authenticate the clients. All of the clients and the service are running in appPools in IIS6 as specified active directory users. I have added the service as a service reference to the client project in Visual Studio 2008. This works fine in the development network. To run it in the Production environment I need to change the URL and the UPN at runtime to the production values, but whatever I try it just throws errors? In fact the only thing that worked - but isn't really practical - is when I removed the development service reference and added the production service reference to the project using Visual Studio before deployment. Surely there is some way to change the endpoint at runtime??? I must be missing something simple. Please help! :)

Here is the relevant part of the client endpoint:

         < endpoint address ="http://dev.happyfunland.com.au/FunService.svc" binding ="wsHttpBinding"

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

using the linqDataSource control programmatically (dynamically)



my scenario is this: I want to use the linqDataSource control to bind data to a gridview for it's efficient built-in paging and sorting features *but* I don't want the data to be bound until the user has input various search parameters, so I need to bind the data from a button click event. Also, the search options will be somewhat complex in that there will be several optional search parameters, via various dropdowns and textboxes, so I can't just declaratively/statically setup all the WHERE parameters on the linqDataSource (at least I'm assuming I can't, or that it may result in poor performance if I do and just assign default values like the everything wildcard '%' for the cases the user doesn't use a particular search parameter). Given that brief description, here is an example of what I'm doing, but with only one WHERE parameter for simplicity, the real code will be adding anywhere from 1 to about 12 WHERE parameters depending on how the user sets the search options in the GUI.

<asp:LinqDataSource ID="ldsMain" runat="server" 
        Select="new (field1, field2, field3, etc..)" 

Search for a string in my datasource dynamically


I am displaying an Rssfeed on my page by using XmlDataSource and Datalist controls.

I want the user to be able to limit the information that is returned to my datalist.  To do this I have a textbox on the form that allows the user to enter their search criteria.

I need to be able to dynamically create a query string utilizing the information that the user entered in the textbox.  I am also using a drop down list and allowing the user to select whether they want to search in the title, description, or all parts of the xml file.

I am having trouble figuring out how to reference the data contained in my textbox in my query string.  Where the query string says 'asp', I want to replace 'asp' with the content from my sSearch variable.  Can anyone tell me how to reference my variable in the query string???

string sSearch = txtSearch.Text;
        string SQuery = "";

        if (DropDownList2.SelectedIndex == 0)
            SQuery = "[contains(title), 'asp')]";

Persist data in a dynamically populated ListBox in a user control


Hi All,

I am trying to persist data in a dynamically populated ListBox in a user control. Here are the details

I have a user control which contains a a listBox and button. On Page_Load of user control I am populating the ListBox control with some values. On Click of button, I am trying to fetch the values which I have selected in ListBox. Though this seems very simple and straight forward I am unable to fetch values.

My Page_Load Function

void Page_Load(object sender, EventArgs e)










My Click Function

Protected Void Button1_Click(object sender, EventArgs e)


       string strValue = listBox.SelectedValue



I have placed brake point at Page_Load and on click function, I am seeing that the moment the breakpoin

Setting default localization



I ever thought that I can set a default localization if the users one (which is set in the browser) isn't available.

I've implemented my localresource files for localization. The start.aspx.resx contains all texts and elements for German use and the start.aspx.en.resx for English users. When I switch the language in the browser settings from German to English everything works fine and the english text is displayed. But when I switch to an other language which is not German or English, it takes defaulty the german resource files.

I've set

UICulture="auto:en-US" Culture="auto:en-US"

as well, but it didn't assume the .en resource file automatically. (For example when I enter the website and switch the browser language to French or Italian it should take the english resource files.)

Thanks and regards,

Problem in accessing resource file dynamically.


Steps I have followed are
1.I have created myres.en-GB.resx file at C:.
2.then created locale specific myres.en-GB.resources using resgen at c: only,

4.I have created one web application using vs 2008 & then build it.
5.Then placed both resource file & dll in web applications Bin\en-GB folder.
6.Anf finally written code at page load like

            Thread.CurrentThread.CurrentCulture = info;
            Assembly asd = Assembly.Load("ClassLibrary1");
