Assign A Value To A Databound Textbox?
Apr 24, 2011
I am experiencing aproblem in my VB.NET App. The salary form is a databound form in my app to a linq data source. There are several text boxes to enter and calculate different salary fields. e.g. Basic Salary, Budgetary Allowance and Adjusted Basic Salary...
all the above three controls are bound to the datasource. now on the Leave events of the Basic Salary and Budgetary Allowance there is a function to calculate Adjusted basic salary.
The problem is i dont see the calculated amount in the adjusted basic salary but i see only the underlying data in the database instead of the programmatically calculated amount.

It appears that I cannot assign the selectedindex for a databound listbox if it has no parent, but I can do so if I have populated the list "manually" from the same datatable. In my code example, the "if" line toggles between loading a list via data binding and loading a list "manually" (both use the same data table). In each case I attempt to set the selected index afterwards. With manual loading, the selected index is set; with data binding, an error is thrown (which can be avoided by assigning the listbox a parent, but the "manual" equivalent doesn't need this). Is this a bug?

Normally I would create a form and handle the binding of controls myself. However, the current table I'm working on has 180 something columns so I decided to use the BindingSource to control the amount of code I have to write. This has all worked well until I try and call the value of one of the textboxes.
So.. I bind my form like so: Me.MyTableAdaptor.Fill(Me.MyDataSet.MyTable)
Whenever I call a textbox e.g.: Dim myVar as String = txtName.Text myVar remains "" or Nothing. I just can't get myVar to equal what is typed into the textbox that is databound.
Is there anything I can do. I know that binding isn't the recommended use, but I really could do without having to write the insert, select, and update commands for 180+ columns.

All - I have a form that has two databound textboxes on it. To keep it simple, they are: Quantity & Value For BOTH of these text boxes, the TEXTCHANGED action will multiply the two and present the result in a LABEL. This works 100%.

For BOTH of these text boxes, the TEXTCHANGED action will multiply the two and present the result in a LABEL.This works 100%.NOW - If I choose to add formatting to either of these text boxes, the calculation will not work. As one might guess, QUANTIY is formatted as NUMBERIC with zero decimal places and VALUE is formatted as CURRENCY with 2 decimal places.

I have a databound textbox that I would like formatted as a phone number ((###) ###-####), instead of being displayed as 10 numbers.
I'm using this on a databound label, which works fine. The same doesn't work on a textbox, though.
phoneNumber = CDbl(lblPhoneNumber.Text)
lblPhoneNumber.Text = phoneNumber.ToString("(###) ###-####")
Anyone know of something that will work with a textbox?

I have an application in VB.Net that displays the results of a math operation to a listbox. For example I have the 12345 + 12345 = 24690. What I'm trying to do is to have the first 2 numbers (12345 and 12345) copied to 2 different textboxes when listbox item is selected. Here's the code I have so far:
'Make sure that we have a selected item before continuing
If listBox1.SelectedIndex = -1 Then
Return
[Code]....
During runtime it only works with index 1 when it gets selected. I have 10 records being displayed (0 to 9). None of other indexes are being shown at the textboxes.

I am trying to assign a dataset to the TAG property of a textbox control in my application. The code seems to do the assignment without any error but I cant see the property TAG name or the assigned value using quickwatch etc. etc. The TAG property name does show in the design window.
Is this property useable in my version (academic 2002 version 7.0) or does the TAG and any assigned value it holds not show in quickwatch. I can only find 1 reference which seems to suggest the TAG property is not supported in early versions, but would prefer a definitive answer.

am explaining this stupidly, but I'm still very much a VB newbie. This is a question about uni work, but it's not an assignment/test, just a little optional extension task.I have three text boxes, the first one is where the person's name is entered and the next two are where you enter the (same) person's score for two tests they have completed.

As the title says I have a form with many databound textboxes. some of these boxes have data in them and some are empty. I need to add them altogether, so far all of the conversion methods I have tried err out when they run into an empty string, except Val, but then Val won't handle the string with a $ in it. I've tried decimal.parse which handles the $ but not the empty string. So I seem to be in circle that I can't get out of.

Admin assigns the authority and get a new form to the new assign in with vb.net & access. I am not sure about this,I need a way to do the new form assigned? How?Actually, this project is the admin will assign the authority to a manager, and the manager will get the password to log in. Then, the manager once log in and will get a form to set the rooms who is going to use and date, etc, this is multi-manager to handle the room setting jobs.But, I think, I got stuck, I am not sure how to do the new form, HOW DO YOU ASSIGN THIS NEW FORM FOR EACH NEW MANAGER?????? THIS IS VB.NET WITH ACCESS.

I'm trying to add a new row to the database using databound textbox's but they keep adding blank rows to the database. If i use textbox's that arnt databound the info will get added
This doesnt work when using a databound textbox - it simply adds a blank datarow with no information
vb
Dim row As DataRowView = CompanyDetailsBindingSource.AddNew() row("CompanyName") = CompanyNameTextBox.Text() CompanyDetailsBindingSource.EndEdit() TableAdapterManager.UpdateAll(MainDataSet)
However if i use a textbox that isnt databound it works and the data is added to the database
vb
Dim row As DataRowView = CompanyDetailsBindingSource.AddNew() row("CompanyName") = TextBox1.Text() CompanyDetailsBindingSource.EndEdit() TableAdapterManager.UpdateAll(MainDataSet)
Is it possible for all the databound textbox's to be added to the database in one go without having to manually add them to the code?
e.g. Why wont this add a new row and insert all the data in textbox's to the database but if i change the AddNew to EndEdit it will update all fields at once?
vb
Me.Validate() Me.CompanyDetailsBindingSource.AddNew() Me.TableAdapterManager.UpdateAll(Me.MainDataSet)

I have a combobox that is bound to a dataset (via datatable and datatableAdapter). The combobox displays the current data in the table as it should.I have programmatically added the string "ADD..." to the list at the form.shown event:[code]when the user then click on (select) "ADD...", i open a new form to allow the user to add a new item to the list.The code i have behind the "ACCEPT" button on the new form stores the NEW value to the DATASET. I have verified this by previewing the data in the dataset.My problem is getting the combobox to reflect the changes to datatable to which it is bound.[code]

I think I already know the answer to this, but I figured it would not hurt to ask.
Is there any possible way to nest Databound DataGridViews in .NET? What I would like to have happen is for each row in the DataGridView to have a button to expand, which would then give me a DataGridView underneath that. I would like this nested DataGridView to also be able to do this, so I could go n levels deep with them.
Is this possible with the .NET Winforms standard DataGridView? (Or another standard .NET control?) I have seen people reference some third party controls, however they are really expensive, and I don't really want to go that route.

I have cascading data-bound combo boxes, however, if the second of the two boxes does not have the value, I am trying to change the data source of the original process to the default selection.
However I am getting errors no matter what I try to do to get the combo box to clear.
cboSubSystem.SelectedIndex = -1
cboSubSystem.DataSource = Nothing
Call cboSubSystem.Items.Clear()
[Code]....
Currently: "Items collection cannot be modified when the DataSource property is set." at the Items.Clear If I try to remove the clear, I get "Cannot bind to the new value member. Parameter name: value" at the valuemember set

I have a combox that is run-time bound to a table that is run-time built and populated from a text file. I have set the combobox autocomplete mode to suggest and the source to list items, but only the 1st item will work. Ok so here's the code:
Private Sub SetStateComboBox()
'set autocomplete for combobox
state_cmbx.AutoCompleteMode = AutoCompleteMode.SuggestAppend[code]....
The file is a text file with a list of the 50 states and their abbreviations in the format : stateName - abbr.Now what happens is the data is displayed correctly, but when I begin to type a letter for the autocomplete the only letter that shows anything is the "a" and it will only show the very first item in the text file.Everything else does not display with the autocomplete, but does show in the list. I have tried variations such as adding the data as items like this:
Private Sub SetStateComboBox()
'set autocomplete for combobox
state_cmbx.AutoCompleteMode = AutoCompleteMode.SuggestAppend[code]....
This way does not allow any autocomplete when I begin typing but everything is in the list. I've also tried converting the table to a customautocompletestring and still the same results.The only way that I have been able to get it to work is be entering each state as an item: state_cmbx.items.add("Michigan - MI"), then it works correctly.Also the combobox dropdownstyle is set to dropdown, and I'm using visual studio 2010 ultimate and coding using VB.

All I want is to enter text into a databound combo box. If the entry is not in the list, then the user should have the option of updating the table that the combo box is bound to.The way I have set up the project is by dragging objects from the toolbox and having the application set up the datasource through the data sources tab. This in turn creates the bindingsource, dataset and tableadapter.For updating the combobox I have added code into the leave event. This does indeed update the client table as required. However, the id stored in the quotes table is -1. How do I make sure that the correct id is stored that references the newly added client record. For your information, the client table only has an id and clientname column.
The code is as follows:
[CODE] Private Sub ClientComboBox_Leave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ClientComboBox.Leave
Dim con As New OleDb.OleDbConnection
Dim dsClients As New DataSet
[code]....

I have a datagridview which is bound to a table in a database. In said table, I have a field called Date and a field called Time, among other various fields. By default, I see that VB.NET attempts to help me by formatting the Date and Time columns for me, however I would like to do it my own way. I checked the columns' DefaultCellStyle fields and found them blank. Apparently, its current behavior is defined elsewhere. How would I go about removing the default formatting that VB.NET put in place to make room for my own?
