View 6 RepliesRaise Event Because A User Didn't Not Select A Checkbox Option After Choosing A Certain Value In A Combobox?
Aug 4, 2011I 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?

View 2 RepliesMake DataGridView TextBox Cell A ComboBox Cell When It Has Focus
Dec 23, 2011I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."

Use Raise Event To Raise A Programmatically Added Event

View 2 RepliesHow To Change Cell Original Value In Formatting Event Of DGV
Aug 25, 2011I'm developing application in VB.NET 2008. Whatever I'm formatting cell that should reflect on original value. In Cell Formatting Event, e.Value=format(e.value,"0.0") means it is formatting data but original value is not changing on cell.
But I tried like this
Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
With DataGridView1
If e.ColumnIndex = 0 Then
e.Value = Format(e.Value, "0.0")
.Item(e.ColumnIndex, e.RowIndex).Value = e.Value
End If
End With
End Sub
It is working for normal datagridviews but if I do the same for databound datagridview , data are flickering... (i,e cellformatting event is executing always). How to change original value of cell in cell formatting event ?

Datagridview Cell Textchanged Event?
Apr 25, 2011I was wondering if there's an easy way to make a cell textchanged event for a datagridview, like you have the textchanged event for textboxes, an event that gets triggered everytime the user press a letter/number/symbol/backspace/space, so i can check in that event if the datagridview has changes and whether i should enabled my save button to save the changes made.
Or is there a better way to check whether i need to enable my save button?

Custom Control And Datagridview ComboBox Cell Back Color
Jun 5, 2009I have added a custom Control to my project, but every time I edit it and rebuild the form that I use the custom control in adds the project name in front of the control and won't compile. i.e. Project name = MyProject, Custom Control name = MyControl. When I rebuild the project after editing my control I get an error, MyProject.MyControl doesn't exist. If I remove the MyProject from the line it compiles and runs fine until next time I edit the custom control.
I can't figure out what I would be doing wrong to cause this, or why it is putting the project name in front of the control, but then not accepting it. I am also struggling figuring out how to change the back color on an individual cell in an Datagridview Combo Box. The style.backcolor property of the cell doesn't seem to do anything.

DataGridView - Change Cell Color If Particular Value?
Apr 26, 2010I have a bunch of columns in a datagrid view (date, transaction type, amount).If the amount in a row is '150.00', I want to make that cell red.I made a Private Sub and run this after the datagridview is filled.
Private Sub ColorCells()
Dim ColumnCount As Integer
ColumnCount = dgvLedger.ColumnCount - 1[code].....
However it seems to have two bugs. When it is first run the first time when the form is loaded, it doesn't put the rows with 150.00 in it in red.If I have a button on the form and set it to run this Private Sub, then it runs through it again and will color the ones in 150 as red.If I resort the datagridview by clicking on a column, they all return to green again, and it looses the formatting.
