Make A Data Refresh / Reload Work

Aug 4, 2009

I've spent several hours reading through posts trying to make a data refresh/reload work and I can't.After adding a new record to the underlying table (using MSSQL) I need the datasource for that table to show this new record. My understanding is that using BindingSource.ResetBindings(False) is supposed to fetch a ew set of records and also update any control bound to it (ie ComboBox).Neither of this is happening. The new record is not there when using the navigator. The ComboBox does not show the new values either.It seems that this would be a simple basic command in VB, alas, I can't find a way to do this cleanly.I'm using SQLSERVER 2005 and VB.NET 2005. Controls are all bound to datasources...

Reload Page Data Based On Dynamic DropdownList Selected Value

Oct 26, 2011

I have a bit of a tricky scenario. It consists of some partial problems for which I have individually found solutions, but I couldn't find anything that makes it all work together smoothly.

-Upon selecting an item in a datagrid, a new page loads with the details regarding that entity.
-The entity represents a product that can have any amount of variants (such as a t-shirt's color or size)
-I dynamically add dropdownlists to this detail-page that represent these variants (there can be any amount of variants, and each variant can have any amount of different values, each value or combination or values from different variants representing a unique product entity)
-Upon selecting a different variant in a dropdown, a delegate is called that will change the session variable to the productId associated with the selected variant and a postback is fired that will reload the page with new data based on this productId

The problem: the postback is fired BEFORE the dropdownlist's (OnSelectedIndexChanged) delegate is called. Since this delegate defines the productId in the session, the new to-be-used productId isn't known at the time of postback.

Result: loading the correct data in the page is always delayed by one postback. Each time I change the selected index of any of the dropdowns, the page is loaded with data based on the session variable that the PREVIOUS OnSelectedIndexChanged delegate of the dropdown set.

I have a LoadData() method that sets the values of all textboxes, fields, labels etc. based on the productId stored in the current session. This method is called on Page_Load.
Private Property CurrentProduct As Product
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
LoadData()
[Code] .....

It seems that I haven't been completely clear on what does and doesn't apply to this scenario regarding Page Lifecycle.

1) My dropdownlists are added dynamically, which works fine on the first page_load.
2) The content of the dropdownlists is defined by what entity's details i'm loading on the page.
3) What entity's details I'm loading on the page is at first(not-postback) defined by the product I selected in a gridview in the previous page.
4) At postback, this entity is based on a sessionvariable containing the id of the entity.
5) This session variable is defined by what item in the dropdownlist I select.
6) This dropdownlist dissapears after postback since it's not defined on the page, but dynamically. So is the event.

So my guess would go towards some clientside script that stored the selected value before postback, but then I would be clueless on how to get that variable to the server since the logic that retrieves the entity is in the business logic layer which is far away from this page..

I have a code that binds the data from the database to textboxes. The problem is I want to make one of the textboxes Payment use a dollar sign.I tried formatting it as shown in the code below but only the first record gets formatted, the rest do not. When I click the next button, the dollar sign disappeared.

bs = New BindingSource(ds, ds.Tables(0).TableName)
Me.txtPayment.DataBindings.Add("Text", bs, "Payment")
Me.txtPayment.Text = Format(CType(txtPayment.Text, Decimal), ("c"))

I have tried everything else I know, FormatCurrency but no luck.Payment is the name of the column in the database, the data type in SQL Server is Small Money.

Dec 2, 2010

I would like to kindly ask if there is a dictionary in vb.net?

8 = TUV
3 = DEF

if the user had input the numeric data on textbox1, then the alpha phrase will show on textbox2.

What i want to run is that if i press the "execute" button, it will look for a word than can be create using these letters ( e.g COMPUTE )

Then it will display the word "COMPUTE" on textbox3.

Is there a function or method i could use to do that?

Possible To Use Exclamation System Event To Validate Data Capture?

Aug 23, 2010

In a Windows XP Pro environment, my system uses a mainframe emulator in a window in which a scanning application is running. The data populating the mainframe app comes from various instruments, scales, barcode scanners, etc.. The data inputs are captured by a winwedge type RS232 data aquisition software.

When all the data is processed correctly, the mainframe application sends an "operation completed" message and creates an exclamation system event associated with a specific sound to inform the user.

My goal is to create a MS Access application that would use the Exclamation system event to validate writing the barcode that was just read to a database without further querying the mainframe, creating a local database. I only want to write the barcode when the mainframe application completed and therefore played the sound.
