I have an app where I need to dynamically choose an SQLDataSource for a GridView so I can use 1 of 2 stored procedures, depending on who is logged into the system. My problem is that I am using logic like this, in the button click...
If Session("SiteType") = "Type1" Then
GridView1.DataSourceID = "SqlDataSource2"
Else
[code]....
This happens when you click the button that reveals the panel with the gridview in it. The user then makes changes (basically adjusting a text box on one or more liens of the grid) and then clicks "save". However, the gridview no longer knows its DataSourceID once this happens, so when I try to go through the gridview's rows - there are none.
If, in the save button's click, I put the same code, it (of course) blanks out any of the data changes I made in the form. So, simply put - how do I dynamically choose the SqlDataSource, but only one time, so that the program then keeps that SqlDataSourceID associated with the gridview until the end of the cycle? Is this a ViewState thing? I don't totally understand ViewState...

I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

I have a form that I am adding a set of buttons to. I am adding an event to those buttons. I need this event to function slightly to determine what button was pressed.
I need the button to simply set a string variable equal to the clicked buttons text so I can determine what button was pressed.
How can this be accomplished?

Using VS 2005 and SQL Express 2005. This WinForm application runs fine on 5 out of 6 stand alone computers that is it installed on. The 6th computer is slightly older running XP sp2.As I understand it, using DbDataAdapter will perform the open, close and dispose functions for you. Therefore, Pooling should not be an issue. I am thinking that the default 15 second time out setting may be the cause?? There is some MultiThreading that will also use DbDataAdapters in the same manner but only 3-4 would be firing at the same time.The connection string is Data Source=(local)DataBase;Initial Catalog=Code;Integrated Security=True The command which throws the exception is If CodeDataAdapter.Fill(CodeDataSet.CodeTable) > 0 Then...So I am thinking that adding Connect Timeout = 60 to the connection string even though the 15 second default seems like a lifetime. Could this 15 seconds be eaten up if some other process or application takes over?

I have placed a few radio buttons in a panel, but I have a weird problem where they require 2 clicks to change their state.If one of the radio buttons is checked, and I click once on another radio button, this will uncheck the checked radio button leaving no radio buttons checked. I then need to click the radio button a second time to change its state to checked.

I have this code.
Code:
Public Class Form1
Dim NPB As Button
Dim x As Integer
[code]....
As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

I'm currently implementing an inventory screen, a simple grid of picture boxes which displays what the player is carrying (read from a simple array of items).
I can create a nice array of picture boxes (allowing me to easily change their .image property to display items) but now I would like to capture a click event on these newly created picboxes, so when one is clicked, the items attributes are collected from the array and displayed below.
For a picbox created in the designer, this is easy, as I just double click the control, and enter my click event in the sub that is created. How would I do this for a code created picbox however?
Here is the code I use to generate my array once the inventory form loads:
Private Sub Inventory_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim x, y As Integer
[Code]....
I have done a few tests, and I know that the names of the boxes are pb00, pb01 etc, but I cant seem to make this work.

I have a form to edit data, with a manually created navigator.Everything works, including the record movement, saving and cancelling changes, etc.My question is...how can I detect if there have been changes to the current record prior to moving to a different one?If the user has made changes to the current record and tries to move to a different record without saving them, I want to prompt him to save.All of the events I've found don't detect a changed record until AFTER the change record has occurred.I assume that typing something in any of the text boxes has to implicitly call the beginedit method.Does that not set a flag or generate an event I can use to set my own flag?
I've looked around here and seen stuff about capturing key down events, looping through the text boxes, etc.Is something this normal really that difficult?If I wanted to write 50 lines of code to do stuff I'd be using C instead of VB.I'm switching from Delphi to VB because Delphi costs $2500.But if I have to spend 5 times as long trying to do standard stuff like this...maybe I need to rethink that choice.

I plan on viewing the game through a webview control, which I believe is perfectly possible... unless I can't see Flash/Java content? I've been wondering how would you "simulate a click" in the web view control? And, of course, keyboard input?

I'm trying to make a form that when it is return to, it will have the same state for the controlsI have 3 .net pages, testa,testb,testctesta, sets up the session and has a button to go to testb. testb has a check box and a button to go to testc. testc has a button to return to page testb.I want it so when we leave testc, and then come back the check mark will be in the same state, but it is not. it stays as uncheck when I go from page testc back to page testbThis is what i did,On the page load event, I set the check box equal to the "button" Session variable. On the button event I save the button checked state in the Session variable and call page testc
Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
Server.Transfer("testb.aspx")
End Sub

I have a label's value that is posted back from a previous page and I want to use this label to do a simple calculation in the current page, but when I do the calculation the page (refreshed) the value of this label and automatically deleted the value (Since there would be no value in postback when it refreshed).
Here is the code behind file:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Label2.Text = Request.Form("Hidden1")
End Sub
and here where I want to use the label
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Stotal As String
Stotal = Val(Label2.Text) * 10
Label3.Text = Stotal
End Sub
How can I save the value in the page via view state or any other method?

I have an Obout grid that I have been trying to work with and I put all of their code in my site so that I could have my grid stay expanded when the page does an automatic refresh.How or what is the correct way to code for a If (Page.IsPostBack) code.Next is there an online free convertor, translator, for javascript to VB.NET; if not is there someplace that I can go to where they will explain the different meaning of the javascript in comparision to what it would mean in VB.Net (such as var I think means dim or it could mean something else I am not sure.)Final is there a good source on grids and how they work with a view state or a session? But it needs to be basic as I am still trying to understand all three of those processes.

I have a grid view with a nested text box in it. I would like to turn view state off but the fact of the matter is when data is posted, the text boxes inside the gridview aren't available (there are no rows in the gridview on postback)I am using ASP.NET 2.0 so would this fall into control state, not view state?
Sample ASPX code of the gridview:
[Code]...
Control's information is not stored in the View State (for things like selected value and .text etc.)Control state, introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state. A page developer can disable view state for the page or for an individual control for performance. However, control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.[URL]..
