Display An Image From Directory When A Checkbox Radiobutton Is Activated?

Oct 8, 2010

I 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.

DataGridView With A Cell That Is A CheckBox. Reading The Value Of The CheckBox?

May 15, 2011

I 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?)

Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim whichGrid As DataGridView = CType(sender, DataGridView)

[code].....

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.

Re-sort A Combobox From Checkbox-state?

Mar 13, 2009

Hi,I´m trying to build a form that allows user to choose if he want the combo-boxes sorted or not.

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 ?

VS 2005 Checkbox In My Application - Fetch The Data From The Database And Add It To The Dropdownlist Of The Combobox

Aug 31, 2009

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.

Raise Event Because A User Didn't Not Select A Checkbox Option After Choosing A Certain Value In A Combobox?

Aug 4, 2011

I 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?

Add Checkbox To Datagridview?

Aug 12, 2011

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.

Checkbox Within A DatagridView

Jul 1, 2010

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.

C# - Checkbox In Datagridview Cannot Be Changed?

Dec 30, 2009

I'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?
