Runs with no errors but the text doesn't show up. Any ideas?

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

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;

' 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?

Thanks for this Ed

With or without the correct caption on the buttons? I'll send my version by mail :)

There is no captions on the button for the code i sent but im after putting a caption on the button for the users to press once again many thanks for your help SImon

[Simon_Whale]

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

Glad that it helped, but you're the one who worked it out :)

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 .... dgBtnCol.UseColumnTextForButtonValue = True Regards, David

Below is what i have working in a project

Private Sub CreateGrid(ByRef data As DataView)
    'the questionno
    Dim BrokerNo As New DataGridViewTextBoxColumn
    BrokerNo.HeaderText = "Broker Ref"
    BrokerNo.DataPropertyName = "brokerref"
    BrokerNo.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill
    Me.DataGridView1.Columns.Add(BrokerNo)


    'the question textbox in the grid
    Dim BrokersName As New DataGridViewTextBoxColumn
    BrokersName.HeaderText = "Broker Name"
    BrokersName.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill
    BrokersName.DataPropertyName = "brokername"
    Me.DataGridView1.Columns.Add(BrokersName)


    'drop down list on grid
    Dim BrokerStatus As New DataGridViewTextBoxColumn
    BrokerStatus.DataPropertyName = "status"
    BrokerStatus.HeaderText = "Status"
    BrokerStatus.Name = "Status"
    Me.DataGridView1.Columns.Add(BrokerStatus)


    'the Answer Question
    Dim Address As New DataGridViewTextBoxColumn
    Address.Name = "Address"
    Address.DataPropertyName = "address"
    Address.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill
    Me.DataGridView1.Columns.Add(Address)



    Dim TelNo As New DataGridViewTextBoxColumn
    TelNo.HeaderText = "Tel No"
    TelNo.DataPropertyName = "telno"
    TelNo.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill
    Me.DataGridView1.Columns.Add(TelNo)


    Dim buttonColumn As New DataGridViewButtonColumn()
    buttonColumn.HeaderText = "View"
    buttonColumn.Text = "View"
    buttonColumn.UseColumnTextForButtonValue = True
    buttonColumn.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells
    buttonColumn.FlatStyle = FlatStyle.Standard
    DataGridView1.Columns.Add(buttonColumn)


    DataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.LightGreen
    DataGridView1.DataSource = data

  End Sub

Thanks for the quick reply. After looking at my code more closely, I was missing the following: 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 ;)

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 ;)

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; ======================== Ref: http://msdn.microsoft.com/en-us/library/ms171619.aspx[^]

Hi, I was pondering quite some time over this issue. The NullValue property did the trick :) Thanks for posting this! Kind regards, Bob Stanneveld
