Yup, you set the HeaderText[^] property to Nothing. Try something like this;

VB.NET

buttonColumn.HeaderText = "Hello World"

Thanks for the reply but that didn't work

the example was taken from MSDN grid button example

You're right. I've taken the example, compiled it using SharpDevelop, the example shows the exact same code;

VB.NET

' Add a button column. 
Dim buttonColumn As New DataGridViewButtonColumn()
buttonColumn.HeaderText = ""
buttonColumn.Name = "Status Request"
buttonColumn.Text = "TestText"
buttonColumn.UseColumnTextForButtonValue = True

The HeaderText is the caption of the column, my bad. And yes, this code should have changed the caption of the button within the buttoncolumn.

It seems that the example works. Can you post your version of the code?

Re: datagridview button column - text not displaying

31-Mar-10 1:09

Ed,

Thank you, you are a genius worked out the problem from your example.

During my experimentation / design layouts i wasn't adding a datasource to the grid. so it was displaying the first empty row.

I then created a simple list of integers and set that to the datasource of the datagridview and the text shows up on the button as expected.

could you assume this is how its suppose to work?

Many Thanks
Simon

It's one way that it can work - there's a lot of ways to fill a datagridview. And yes, it would be a good way; it's easy to read, easy to comprehend and thus, easy on maintenance.

I'm having the same problem. I read the postings, but I don't understand how this was solved.

Here is my code snipet:

Dim dgBtnCol As New DataGridViewButtonColumn()

dgBtnCol.Name = "SelBtn"
dgBtnCol.Text = "Select"

DataGridView1.Columns.Add(dgBtnCol)
Me.DataGridView1.DataSource = DT       ' The datatable is already populated with data at this point

The grid displays, but the caption on the button is nothing. How did the original poster solve this ?

I forgot to add the following line of code ....

<br />
dgBtnCol.UseColumnTextForButtonValue = True

Regards,
David

Thanks for the quick reply.

After looking at my code more closely, I was missing the following:

<br />
dgBtnCol.UseColumnTextForButtonValue = True

My code is now working.

Thanks.

Another workaround is to set the NullValue of the column to the desired text.

In a project of mine I have a DataGridView where the user can add rows manually. The text for the button didn't appear and nothing seemed to work. I then remembered that there is always a NullValue property and after I set this, the text appeared on the button Wink | ;)

DataGridViewCellStyle8.NullValue = "Some Text"
Me.AddStillstand.DefaultCellStyle = DataGridViewCellStyle8
Me.AddStillstand.HeaderText = ""
Me.AddStillstand.Text = "Some Text"

Just in case someone else is having a similar issue Wink | ;)

The code is working. just make sure that you apply this after assigning the datasource to your grid control.

Step 1. After assign datasource to grid.
// Add a button column.
DataGridViewButtonColumn buttonColumn =
new DataGridViewButtonColumn();
buttonColumn.HeaderText = "";
buttonColumn.Name = "Status Request";
buttonColumn.Text = "Request Status";
buttonColumn.UseColumnTextForButtonValue = true;

dataGridView1.Columns.Add(buttonColumn);

step2.

just after adding the columns register your click event like below.

// Add a CellClick handler to handle clicks in the button column.
dataGridView1.CellClick +=
new DataGridViewCellEventHandler(dataGridView1_CellClick);

step 3.

now on below event,
void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)

make sure which button is clicked when multiple are there.

if (e.RowIndex < 0 || e.ColumnIndex !=
dataGridView1.Columns["Status Request"].Index) return;

// Retrieve the task ID.
Int32 taskID = (Int32)dataGridView1[0, e.RowIndex].Value;

// Retrieve the Employee object from the "Assigned To" cell.
Employee assignedTo = dataGridView1.Rows[e.RowIndex]
.Cells["Assigned To"].Value as Employee;

Not really a visual basic problem, but i didnt know what forum to use, but my code is in vb.net Smile | :)

I have a program which has to print a bunch of documents, after printing a random number of documents this error is thrown: "Runtime.InteropServices.COMException (0x80010105): The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT)) "

I have written this testprogram which throws the same error

        GC.WaitForPendingFinalizers()
End Sub

Sometimes it throws the error when opening the document, the other time when printing the document..
The problem occurs on a Vista Enterprise SP1, Office 2003 and only on a HP Laserjet 2430dtn printer. On another type of printer the code runs perfect, also on a win2000 the code runs perfect. I tried installing other drivers for this printer, same problem...

Does anyone have an idea what i can try to solve or work around this problem. I know my code works when i close word and close the document and call the garbagecollector for each document, but then it takes about 17 seconds per document to print out...

If i don't print at all it also works Poke tongue | ;-P

Thanks in advance.

How can I validate that a user has entered a correct phone number into a text box? The existing form uses a textbox to input the phone number. Apparently the only valid entries are in the following form: xxx-xxx-xxxx
I am not sure how to pass values into a procedure or function.
Can someone help?
Thank you

If you are using VB.NET, you can use "regular expressions" to validate your field matches a particular format... if you are using VB6 (why??), then you will need to have an event behind your form that passes the textbox's value to a function for parsing.

As Damian S said, you can use regular expressions in VB.Net. Try this function :

Private Function ValidatePhoneNumber(ByVal StringToTest As String) As Boolean

    Dim expression As New Regex("(\(\d{3}\)|\d{3})[- ]\s?\d{3}[- ]\d{4}")
    Dim match As Match = expression.Match(StringToTest)
    If match.Success Then
        Return True
    Else
        Return False
    End If

End Function

Then you can call your function like this :

If TextBox1.Text <> String.Empty Then
       If ValidatePhoneNumber(TextBox1.Text) Then
           MsgBox("Correct phone number.")
       Else
           MsgBox("Not valid phone number")
       End If
   End If

If you want to learn more about regular expressions then I recommend you download a copy of Expresso (google it). It is an excellent tool for learning them.

Hope this helps.

Regular expressions are the best way to go, as you can then embed some real phone number rules such as area code validation and so on.

Alternatively if you are only dealing with the one format allowed then I suggest you use a masked textbox so the end user can't even enter the wrong format.

If you have knowledge, let others light their candles at it.
