Xml - .NET Xmldatasource Doesn't Show Latest Data On Postback
Jul 14, 2011
I've run into a problem that I'm at a loss to understand and/or work around. I'm working on a settings page that updates an XML file. The page has an XmlDataSource with a transform file (to filter and sort the values) and a DataList that is populated from the XmlDataSource. A user can enter a new group name into a text box and click a button to submit the form. When this happens, the new value is successfully added to the XML file.

I want to enable auto updating on my vb app.So I got Project--> Properties--> click the Application tab. Click the Assembly Information button --> Update the Assembly version. Then click ok.Then I build my app. Then I click the Publish Wizard. I specify the location to publish the app. It is an ftp folder.Then I click Next.It asks how will the user Install the app.I select FROM a CD-ROM.then I go next.It asks where will the app check for updates.I specify the same ftp folder.then I go finish. And it publishes to the ftp location.Then I get the setup file from that location and run it on my pc. It loads my app fine. then I build and publish again. But when I copen my app it doesn't update with the latest version.

I'm doing a form to add/edit/delete values from a data catalog. everything goes fine but the Radgrid doesn't update after Submit Button is pressed in the edit/new dialog. i did it before in a more complex form but i can't figure exactly what's wrong.
in the update the data where the new data will be overwritten dissapears after postback. (i have a way to solve this)
mnlib is a library of my authorship to deal with common tasks i know that queries with strings like {$database_name} is not a standart practice, and probably is not recomended, but i have to deal with it . i'm doing almost everything programatically some of the code is ommited because character limit in post Updated: Reduced code, i'm afraid if keep reducing code, i will eventually delete something important to the iusse

I have a ListBox that is only about 4 lines high. After I add more than 4 Items, it attaches them to the bottom of the list outside of the viewable area with out scrolling. Is there any way to either add items to the top of the list or make the latest item visible? I want to keep all the items in the list in the order they were added whether it is oldest to newest or newest to oldest.

I don't understand what's going on here I published my project, and when I create new records and save them, everything gets saved and shows up each time I run the program.I open the database in SQL Server and none of the tables have the new data, but it still shows up when I run the program each time.

I have a user control that contains a search value text box a button, and a datagridview to display what the data adapter found. In the data set designer, I have an ODBC connection to a table, with two SQL queries defined FillByCustomerName(NAME), and FillByCustomerNumber(CUSTOMER_NUMBER). If I preview the data in the designer, I see the data expected. The datagridview doesn't show any data. The functions PopulateGridByName and PopulateGridByNumber do the work. I've tried adding a dgCustomer.show statement, The form that calls the user control has no codebehind code, and throws no errors.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Try
Dim SearchValue As String = CreateSearchValue()

I have a form that has around 4 txtboxes. Data is inserted into these boxes and then a "Save" Button is pressed. I have a GridView added to my form and want to view the entries. The issue I am having is that when I click the save button the data doesn't show up in the DataGridView until I close the application and then re open it.

I have the following code. It works as is, but... I am not always going to have an even number of items in the RSS feed So, at the end of the table, I might have only one table cell on the last row. So, is there a way to count the number of ItemTemplates and AlternatingItemTemplate, so if it is an odd number I would be able to add another cell <td> </td></tr> and close the table row?

I'm using interop.msxml2.dll to open XML and txt files off an Internet server. The response that is received from the server is stored in my application's variables. I've recently noticed that the application doesn't always update the information when it goes to download a file that it has already downloaded in the past. For example, if it downloaded a file off the server when it started up, then when it attempted to download the new, changed file 5 minutes later, it would still return the same value as the first one. Even after closing the application, it would still return the incorrect, older value. How to stop this "caching" of data, and only allow the program to download the latest file off the server.

I'm having a weird problem with a custom Web Control in an ASP.NET forms application. For a web application, I figured that it would save me a lot of time to create a class which inherits from CompositeControl which combines a label with some other control such as a TextBox or DropDownList. This composite control has several properties that wrap properties of the underlying properties (e.g.: EnteredText wraps TextBox.Text). The controls can be used for databinding in the same way as the regular ones, but instead of txtBox.Text = someObject.someProperty you use compositeControl.EnteredText = someObject.someProperty. These controls are then used on ASPX pages and ASCX user controls.

The first time the page loads my structrure is filled correctly. After an AJAX postback all the structure fields are setting to nothing. (It seems that the Dim OldPInfo As New PInfo is called again), but i should better ask the SO Experts.

I have several UserControls in an ASP:Repeater. They are 'Add to basket' User Controls with a text input for quantity and a button to add the item to the basket.
My problem is the value is being reset to 1 whenever I enter a value into the quantity text box. I think this is happening because the containing page reinitialised the repeater (which holds the UserControls) and the quantity is one again before the UserControl's click event is fired.
how to capture the value in the textbox before the Postback occurs, I am happy to stick this data in a session for now.
I am thinking I need something along the lines of PreLoad? But that didn't work for me

How do you make the image in a picturebox vanish when you change an option? I have tried a few different ways that i have seen but none have worked. I have it set so when i change an option in a listbox it will change the picture and data in other controls, however one option in the listbox has no data to fill in those controls and so gets left blank. However when i click on that option right now the images that were in the picturebox before get left behind until i click on another option that has a picture. So how do i remove the picture from the box?

I'm using a DataGridView that gets its data from table in Microsoft Access, one of the fields is a Short Time type record (e.g 16:00) but when the DataGridView is loaded it shows the record as "16:00 12/31/1899" and never shows only the ShortTime.
