View 2 RepliesI am working on a school project to display a photo of a professor when their name is selected using a RadioButton and to display their name, office office hours and so on.
I have their Photos in a directory on my computer
Theonly thing I cannot figure out is how to use 1 picturebox and link the image to display to the radiobutton.
I have tried all kinds of queries on the internet and cannot locate the answer. There might be something with an Image.FromFile command I saw but that might have been from a previous version of VB and I could not get it to work in VB9.

View 1 RepliesI have some DataGridView code written in vb.net. (Nothing is attached to a datasource.)The 4th column is a checkbox cell.How do I detect if that checkBox is checked or unchecked?This code strangely reports TRUE or FALSE at random times. It even turns ON the checkbox in rows other than the row I clicked in. (Huh?)

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
Hi,I´m trying to build a form that allows user to choose if he want the combo-boxes sorted or not. The comboboxes are filled when form is loaded, when user clicks on checkbox (chkSortList) then I want the comboboxes to be re-arranged. Can anyone give a hint how to do that ? Tried cmbMerk.Refresh(), cmbMerk.Update() ... but the sort-order do not change. I can re-load the items to the combo-boxes but is there a better way to do it ?

Select Case chkSortList.CheckState
Case CheckState.Checked

Is that possible to provide a combobox that each item has its own checkbox?I'm looking for built-in component that enables it. I remember it was possible on VB6 but can't find it in VB.NET 2008
View 5 RepliesI have on my form a combobox and a checkbox.What I want to do is when the user checks the checkbox all the values contained in combobox will be selected. So a multi-select for all items of combobox when the checkbox is checked.I tried this:
Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If CheckBox1.Checked Then
ComboBox1.SelectAll()
End If
End Sub
But only one element is selected with blue.
DataGridView TIPs has TextBoxes and ComboBoxes in it and the data comes from an SQL table. I see how to get or set the cell values that come from the ComboBoxes using Item, but how do I access the actual ComboBox events and properties?

I have a checkbox in my application,when the checkbox is checked then i want to fetch the data from the database and add it to the dropdownlist of the combobox.Again when the checkbox is unchecked then i want to ramove all the data from the dropdownlist of the combobox.
I did this
Private Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If CheckBox1.Checked = True Then
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=Etech.mdb")
[CODE]...
When the checkbox is checked then the data is added from the database to the dropdownlist of the combobox but when i uncheck it then the data is not removed from the dropdownlist of the combobox. In the above code i think i need to add an else condition to remove the data from the dropdownlist of the combobox and make it empty when the checkbox is unchecked.......but i cant give the proper else condition in the above code.
I would like to manually insert values in a combobox colum of a datagridview.I am using the DGV as an UNBOUND control.
View 8 RepliesI am new to vb.net and I have looked at other topics. I cannot find the answer I need. OK I have a combobox named cboRaceDesc and five checkboxes (CkRaceAfricanAmerican, ChkRaceAmerican Indian, ckRaceAsian, ckRacePacificIslander, and ckRaceWhite). I was going to post an image, but I cannot.cboRaceDesc has two options...Hispanic and Other. If the user selects Other then they have to choose one of the five checkboxes or it will raise an exception when the record is being saved. I am assuming I would generate the code under the "save" button. I know I need to gather the following information in my code:
If cboRaceDesc.SelectedValue = Other Then
<I am not sure how to code the logic regarding the checkboxes>
<I know I need to use multiple else/else if statements>
<I know towards the end I would generate the exception>
End
Can anyone help me fill in the blanks or point me in the right direction?
I need to change the cell type of an unbound datagridview ROW to checkbox type at runtime. Optionally adding a row of all checkboxes or changing the default type to checkbox is also fine. I see many examples for setting a column type to checkbox but I don't see anything that operates at the row level. Even operating at the cell level would be fine.
View 1 RepliesI have the code below which works fine when checkbox at Cell 2 is Checked ie., the date is inserted in Cell 9. Now, when I unclick Cell 2 I want the Cell 9 to be cleared. Presently, it is not cleared after unchecking. The code highlighted in Red is the area I reckon I have a problem...

I 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.
View 1 RepliesI have a datagridview (unbound). Fields are Name, Family Name and Phone No and a checkbox colum.There are ten rows in that DataGridView. There is an OK buttonI need to get message of showing which rows user has checked. The message should appear when user clicks OK button.I am not able to get this message. I tried following code in OK button
Dim strCB As String =
dgvChooseQs.Rows(0).Cells(3).Value.ToString

this code which supposedly updates myTable when the check mark is preset on a datagridview.The latter has a checkbox (a bit in myTable) in column 5.The code works but only updates one row no matter how many check are in the column.
View 5 RepliesI have appended a column of checkboxes to a DataGridView using the following:
Dim chk As New DataGridViewCheckBoxColumn
DataGridView1.Columns.Insert(0, chk)
How do I change the checked state of a particular checkbox?
I have tried using the following code:
Dim val2 As DataGridViewCheckBoxCell = DataGridView1.Item(243, i)
val2.Value = True
DataGridView1.Item(243, i) = val2
The last line resulted in runtime error "InvalidOperationException was Unhandled
Cell provided already belong to a grid". Index 243 exists.
I have a checkbox column in the datagridview and also a column named "partqty" which displays the quantity of materails available.. I would want that when the user checks on the checkbox, the quantities of checked rows should be added and displayed in the textbox..

I just want to know on how will I add a Checkbox in each row of my datagridview. First I used a datatable to get all the values from my database and then pass it all to the datagridview. What I want to happen is at the first column of my datagridview there is the checkbox.[code]
View 4 RepliesI've created a Datagridview bound to a Datatable. This Datatable is updated by a event to reflect statistical information as it changes (sub second resolution). I have a checkbox to determine if a row is available for other functions and can be toggled on and off normally if my eventhandler is not receiving my updates.
If my bound Datatable is changed, the checkbox returns to its previous state as soon as the cursor or focus leaves the checkbox glyph (not the cell).
How do I toggle the checkboxes without them reseting without disconnecting my eventhandler?

I need to get message of showing which rows user has checked. The message should appear when user clicks OK button. There could be several message, checking each row one by one, in a loop.
I am not able to get this message. I tried following code in OK button
Dim strCB As String = dgvChooseQs.Rows(0).Cells(3).Value.ToString
Cell(3) is my checkbox. Donot consider Rows(0), at the moment I am just checking value at row 0

I have created a Datagridview by dropping in from the Datasource. After I changed one column to be a Checkboxcolumn but it does not represent the values. In the table (smallint) I have 0s and -1s but it doesnt matter what I enter as True and False Value in the column it just shows that the box is checked.
