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.
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 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 am using nested datalists to display hierarchical data. In the nested datalist i want to be able to bind to a property that belongs to the object that the parent datalist is bound to.
I have a DataList inside another DataList. I want to access the child DataList "dlQuestion" events, ItemDataBound event. Also, I'm tring to find the control LableControl "lblQuestion" in the child datalist. How do I do that? Here's the mark-up:
I have 3 forms, one frmMain - main form, second is frmUserType- childform, and the last frmCreateUserType. In the main form I have a menu item to open my frmUserType, In this form I have a button to open another form which is my frmCreateUserType, In this form I have a button to add records then update the listview in frmUserType. The problem is the listview will not access with my add button control in frmCreateUserType. I tried not to used mdiparent declaration for my frmMain and frmUserType as children and it works, so meaning that the problem is showing my frmUserType as childform?I am using vb.net 2008
Code to open my second form (frmUserType)

I have a tab control, that the user can add/remove tabs as they please. It is an inventory manager, and the tabs are the departments. Everytime a user adds a department, a new listview is cloned and added to the page. Upon form load, i need it to go through the tab pages, and query the database for items matching the department their in. In other words, if the Department column in the inventory database, matches the Tab Pages text, add it to the listview inside that particular page. I've tried several things, but they all end up buggy. Either it adds them all to the first listview, or it skips every other page, or worse - doesn't add anything at all. Here is the code I have, could anyone help me figure out how to:
Cycle through the pages, if any of the DB's rows Department column matches the tab page text, add it to the listview inside that tab page, then move to the next tab page, and cycle through the DB again. Here is my code, a decent start I believe.
Sub FillList()
Dim incs As Integer Dim inc As Integer Dim lst As ListView
I have a tab control in my form and inside it I put a listview. What I wanted to do is populate the listview everytime I clicked on each tab. But I don't know how to do it.
Here is the bit of my code
Public Class Form2 Private Sub PopulateRecords() Dim TSR As New ADODB.Recordset Dim STRSQL As String = ""
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.
[code] the part way at the end where it uses .elements(mySearchInput).Value = "bob" I get a compile error it says object variable not set? my guess is this text box is inside a frame called "mainframe" so how would I access an element inside of a web frame? it works fine on another site without frames?
I've got 2 DataTemplates defined for a Listbox Control. 1 Template is for the UnSelected State and the other one is for the Selected State(showing more detail than the UnSelected State).[url]...
about how to access the Elements inside the DataTemplates from Code behind.
I get it right, but it only finds and returns an element of the UnSelected DataTemplate. But when i search for an element in the Selected DataTemplate i get a NullReferenceException.
i am developing a vb.net application my question is how can i access a folder inside my application ?? for example i created a folder Myfold where i store some .doc files and i want to read them from my code.
In datalist, I hve populated Grdiview.In Gridview , I hve checkboxes. Now i want to get the selected checkboxes names to be insrted into the database when clicking the button.so far i have tried like this
Protected Sub butn_Submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles butn_Submit.Click Insert_CATEGORY_Info()
[code]....
the result is
"foundObject reference not set to an instance of an object. "
I'm building a tabbed text editor and I'm trying to access the richtextbox inside the tabpage.
Dim wordcount As String = "" For Each RichTextBox In tabMain.TabPages(tabMain.SelectedIndex).Controls wordcount = RichTextBox.text Next
right now thats how I'm accessing the control inside the tabpage and it seems to work but it seems like there should be a different or easier way to do this. Anybody know of a better way to access the child controls?
Protected Sub Btn_Click(ByVal sender As Object, ByVal e As EventArgs) Dim Id as string = MyClass.getID Private Sub Sub2(ByVal doc As Document)
' in here i need to access the ID from the above sub the Id needs to be in the btn_click sub cos it reates a unike id every time it is clicked.I am trying to capture the id at the time the button is clicked and store it on a variable.
I have a checkbox and a panel inside of a FormView control, and I need to access them from the code behind in order to use the checkbox to determine whether or not the panel is visible. This is the code that I originally used, but since I put the controls inside of the FormView, it no longer works.
Protected Sub checkGenEd_CheckedChanged(ByVal sender As Object, _ ByVal e As System.EventArgs) If checkGenEd.Checked = True Then
[Code]....
There aren't any errors anymore, but nothing happens when I click the checkbox. I think there needs to be some kind of event to trigger it but I don't know how you can put an event handler inside of an event handler.
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.
