I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

View 6 RepliesI am working with Vb.net. See the code below; I have the following problem - when I click the checkbox (Cells(3)) the value remains 0.00 in Cells(4) unless I click another checkbox is when Cell(4) gets populated with the value from Cells (5).
What I want it to do is when cells(3) is checked, Cells(4) should be populated instantly with the value from Cells(5). Rather than still show 0.00 until another checkbox is clicked. I think th eproblem is in the eventhandler as highlighted

In WPF, I have a Uniform Grid and would like to be able to find the row and column based on the index of a child element.
I know there is a mathematical way of doing this and would rather not use a normal Grid.
If it helps, I can get the total number of rows and columns by using:
Math.Sqrt([*uniformgrid*].Children.Count)
I get this error when clicking on any of the letter buttons in my repeater. The sql statement I have works in sql server, but on my page it just errors out. The only thing that is different is that in sql server I change '@CompanyID' to an actual ID and '{0}' to 'a' so the query will run. All the posts I have found online with this problem say something about this-->{0}, but I don't see anywhere that I might be trying to pass more than one argument or have this wrong.[code]

I have a project in which I have to display a picture box based on:
Which radio box is checked
and
if a checkbox to make the picture box visible is checked. As someone who values clean, good code this is my code and it horrifies me. My question, is there some way to condense the following using cases or some other construct I don't know in VB.net?
If CheckBox1.Checked = False Then
BooksPictureBox.Visible = False
MusicPictureBox.Visible = False
[Code]....
Note- all the images stack on one another, and all of them start without being visible.
I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
[code]....
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?

I have a datagridview that is connected to a table from my database. It displays all the records from that table. The question is this, how can i put a checkbox column on my datagrid for me to be able to delete multiple records from my database? I am using visual basic .net 2005.
View 4 RepliesI have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit).
These two fields have been populated with false and true values.
On my form, I have a datagridview which is populated with various values from tblProjectpatients.
The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values.
I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.
i want to ask about the check/uncheck the checkbox in a column in datagrid.if all row in the checkbox column is not selected, what is the code is.because i want the msgbox appear if the user not check any row.
View 17 RepliesI haven't seen a related thread (yet)I have a VB windows application that uses a datagrid to display a text column and a checkbox column. Only one row in the display can have a checkbox entry = true. If a checkbox is selected, the app is to search the rows and all other checkbox entries are to be set to false.My event handler is: Private Sub dgMember_CellContentClick(ByVal sender As System.Object, ByVal e As ystem.Windows.Forms.DataGridViewCellEventArgs) Handles dgMember.CellValueChangedI first had to have this handler code check a flag and exit if true (when initializing the display) because it was called for each row during initialization.

Interesting problem. I have a datagrid with several columns which are bound to an Access database. Here's the situation...I'm concerned with the 3rd column.This is what I'd like to happen... when the 3rd column(is a checkbox) is checked then column 4(TIME_USER) would be populated with the current time
Basically, this application is meant to keep track of tasks that the user has to do at a certain time of the day. When the user checks the checkbox it would record the time in the database for that task as to when they did it. I found some code from a forum that i changed to fit my needs, but it's not working.

First of all, I'm a somewhat-experienced VB3 Developer, and I'm trying to convert a VB3 app to VB.NET.I got the programming guide (http:url....) by searching the web.The problem I'm having is the syntax for .NET is way different than VB3, and that's OK, but finding the correct syntax is very difficult.I'm trying to eliminate duplicates in a ListBox:
When I access the Programing guide, I see that:
ListBox.SelectedIndex Property
Gets or sets the zero-based index of the currently selected item in a ListBox.I also have Murach's and Stephen's manuals, and they say the same thing.Visual Studio converted The old .ListIndex to a VB6 Function:
If VB6.GetItemString(PlayList_ListBox, I) = VB6.GetItemString(PlayList_ListBox, I + 1) Then
This is Try #1. It generates: VB6 is not declared. It may be inaccessible due to its protection level.Then I read that VB6 is only for converting old code.So then I tried SelectedIndex:
Dim I As Short [code]..........
