How do I access the items of a listview which in a another form inside a panel.
The Listview is inside a Panel........Panel1
Panel1 is in a Form ..................Form 1
I have another form .........Form2, from where I want to input items to Listview in Form 1
is it possible to disable validation of all items inside a panel programatically in vb.net?
i can't seem to figure it out.
i disabled all fields inside a panel, but they still cause the page to validate on submit.
this is what i have now:
Public Sub DisableControls(ByVal parent As Control)
Dim cCon As Control
For Each cCon In parent.Controls
[Code]....
I need to loop inside listview and its columns Sub Items. I'm currently using this.
For Each item As ListViewItem In ListView1.Items
For Each si As ListViewItem.ListViewSubItem In item.SubItems
Next
Next
But it over loops on the items causing the code to produce incorrect tasks.
I have a form called Form1. wherein Form1 has a split panel container. on the right side of Form1 is a web browser window. the right side are the buttons. one button there is calling another form. but there's a problem on this Form called Form2. I have google earth EXE and it's component files together with the same folder of the project. The Form2 will call the googleearth.exe file now... I know the program syntax

I show forms in a SplitContainer Panel, but since the FormBorderStyle is set to none I'd like to apply a drop shadow. The following code works perfect if the form is not inside the panel

I have a project with 2 Forms. Form1 with 2 SplitContainers and the code below to show the Form2 inside SplitContainer2.Panel2. Form2 with no borders and orange color.
Public Class Form1
Declare Auto Function SetParent Lib "user32" (ByVal hWndChild As IntPtr, ByVal nWndPArent As IntPtr) As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I want to resize Form2 when change Form1 size by mouse.I use frm.Size = SplitContainer2.Panel2.Size but look in pictures what happen:This is Form1 without Form2 inside Panel2 This is the application in first run. Form2 showed in Panel2 with orange color.The size is OK (frm.Size = SplitContainer2.Panel2.Size)Now i have change the size of Form1 with mouse click (or move form corner).Look the Form2 in Panel2. Didn't change size. Stay in first run size.How to change the size of Form2 when i change the size of Form1?
I have this simplified code:
<asp:ListView ID="ListView1" runat="server" DataSourceID="sqldatasource1">
<ItemTemplate>
<asp:Button ID="ButtonTest" runat="server" BackColor="Silver" Text="Add to Cart" />
</ItemTemplate>
</asp:ListView>
I am trying to run some code behind the button but I don't know how. I can't access it within the listview. Not that this is important, but im trying to get information from the current listview(the product ID) and pass it to the next page.
I have a DataList (Question) inside the ListView (Section). ListiView is to hold the sections. DataList holds the questions of a section. Let's say I have 3 sections, each section has 2 questions.
<asp:ListView ID="lvSection" runat="server">
<LayoutTemplate>
<div id="itemPlaceholder" runat="server" />
[code]....
But it does not get anything back, question always gets nohting. I think it's because there are 3 DataList inside the ListView now, due to 3 sections, and it cannot find DataList dlQuestion anymore. How do I access these DataLists of ListView from the code behind? I need to loop through each control of the DataList .
I am not really sure how to ask this question. I have been teaching myself vb for about 3 months. The book I am using is pretty good about explaining things and what I can't figure out I can find different examples on the web. I can't find out how to access windows control panels from my app. For example if I type firewall.cpl at the run line it will launch the windows firewall.
View 1 RepliesI have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

So i have a "game", and the login screen for the game is built into a panel. When you click the load button the panel shows up inside the form, and you are able to type in your username and password. what i am trying to do is make it so the user is able to drag that login panel anywhere inside the game form; just to make it a bit more advanced then just a fixed spot.

I have a small application which has a MS Access as backend, and the front end is developed using VB.Net 2008. When I click on the listview item and then click delete button to delete a particula list and its content on the database, it is giving me the error as "No value given for one or more required parameters".

I am having a problem figuring out one thing with my program. It's about SplitContainer. To elaborate, I put a SplitContainer on a form. It divided my form into two parts, which I wanted. On the left side panel there are buttons, and when I click on a button I would want to display another form inside the other part of the SplitContainer which is Panel2.

View 12 RepliesI have a question about getting control inside of a panel to appear Here's what I am trying to do:I have 2 database maintenance screens done with both details and grid.
Customer
Inventory
I have all the Customer table data on 1 panel control (pnlCustomer) that has textbox and datagridview controls. The visible property is set to True because this is the first UI that I want to appear when the form loads Next I created another panel for the Inventory data (pnlInventory) and I added contols to that in detail and datagrid views. I placed the Inventory panel directly on top of the Customer panel. The visible properly is set to False My intentions are that when the employee selects the Inventory button that the Customer panel will hide() and the Inventory panel will show().
I have tried a number of things but they do not work. What happens is that when the Inventory button is selected the Customer panel and all it's controls will actually hide but the Inventory panel will not appear. If it is opening, then there are no controls visible...and I checked to make sure that the property of all controls in the Inventory panel are set to Visible = true
Here is what I have tried:
' on form load
pnlCustomer.Visible = True ... also tried .show()
pnlInventory.Visible - False ... also tried .hide()

In my application, I have a data bound form using a binding control (built by the wizard). The application has one primary data screen plus a few more on tabcontrol subscreens.Picture for example that the tabcontrol has two tabs, tab1 and tab2.When the form is displayed, tab1 is visible.Now picture the form or window split in half the top part of the form has a few textbox controls bound to the data and there are a few textbox controls in the lower half of the screen on tab1 of tabcontrol1.There are a few textbox controls on tab2 as well.When the form displays, I can access any of the .text properties of any of the textbox's that I can see on the form and in tab1 of the tabcontrol.BEFORE tab2 is chosen or even, I need to get some of the data from the .text property on a textbox control that is on tab2.I have tried to get the data but as far as VB is concerned, it does not appear to be there UNTIL tab2 is displayed.
To prove this, I put a command button on the form and it simply does this: MSGBOX (mytext box33. text)mytextbox33 is a databound control on tab2 of the tabcontrol1.tab2 is not in focus and apparently, neither is the data.how can I read the .text property of a textbox that is on a form but the form (or tab) is not in focus?
When i click on the link button, it does not show the data from DB... if the part i am updating from DB is outside the tabbed panel then it works fine...

I have a panel inside a formview that is supposed to become visible when a checkbox (also inside the formview) is checked.

I have a picturebox inside a panel, the picturebox is long, and the panel is set to allow scrollbars, which it adds. I can scroll the picture at design and runtime, but how do you scroll it programmatically?
Starting with the picture box with the top set to 0, and then doing this... (using any non-zero value as the lY value)
Dim newLocation As New System.Drawing.Point(0, -lY)
[Code]....
So how do i get the value to change (e.g. to scroll the picturebox!)
But I don't know if i posted this at the right place. I am making 40 textboxes inside a panel. And this textboxes I set it to visible=FALSE. Then I have another textbox named txtNoteam in which once the user will enter a number in this txtbox which is less than or equal to 40, those textboxes will be set to true starting from textbox1 to textbox40 depending on the number entered by the user. Example: user enters 3, then textbox 1 to textbox 3 will be set to visible.
I was successful in doing this except one thing, instead of textbox 1 to textbox 3 will be set to visible, it's the textbox 38 to textbox 40 will be set first. This means it will start from the last textbox to the first textbox instead of from textbox1 to the last textbox.
I need your help on what should I do for this to be able to set it to visible from the 1st textbox to the last textbox or is there any other ways of doing this?
