How to add buttons to datagridview cells not entire column

Question

How do you add a button to cells in a row and not the entire column in a datagridview?

Answer 1

I think Adrian's answer was close. Try something like this.

if ((string)table.Rows[0].Cells[0].Value == "I should be a button") {
   // you can add formatting or values to the button before assigning it here
   table.Rows[0].cells[0] = new DataGridViewButtonCell();
}

Answer 2

I think the best answer if found here: Hide gridview button. All you need to do is to add a DataGridViewButtonCell where you want buttons, and DataGridViewTextBoxCell where you do not. The column has to be DataGridViewButton type.

Answer 3

What I endded up doing was stacking a DataGridView on top of another one. I turned off the border, gridlines, and scrollbars. Then create dynamic button columns to match the main datagridview with only one row of buttons. Then I used the ColumnWidthChanged event handler to resize both the DataGridViews together. Anyway's this was my workaround for now.

See this similar post in SO, probably helps

adding control to gridview

In case Win Form, Check this MSDN post

Column Types in the Windows Forms DataGridView Control

OR this code project post ... though it gives example of adding a image button

DataGridView Image Button Cell

@tmax In that case you can probably put your button creation code in GridView_RowCreated event like below

void GridView_RowCreated(Object sender, GridViewRowEventArgs e)
  {   
     if(e.Row.RowType == DataControlRowType.Header)
      {   
           //Button creation code here        
      } 
  }

Answer 5

private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
    Button btn = new Button();
    //btn attributes
    dataGridView1.Rows[0].Cells[3].Value = new Button();
}

try something like this.

Answer 6

 DataGridViewButtonColumn dataGridViewButtonColumn = new DataGridViewButtonColumn();
        dataGridViewButtonColumn.Name = "Select";
        dataGridViewButtonColumn.HeaderText = "Select";
  
        dataGridViewButtonColumn.ReadOnly = false;
        dataGridView1.Columns.Add(dataGridViewButtonColumn);

Answer 7

After assigning data source to gridviewCTRL. you can add new column with button with below code.

DataGridViewButtonColumn startbtn = new DataGridViewButtonColumn();
startbtn.Name = "Action";
startbtn.Text = "Start";
startbtn.UseColumnTextForButtonValue=true;
int columnIndex = 6;
gridviewCTRL.Columns.Insert(columnIndex, startbtn);

This will add the button to each and every row at define column index. if you want to render condition the AccessibleObject, then you can do something similar to below.

foreach (DataGridViewRow rowdata in gridviewCTRL.Rows)
{
    // this is just an example in my case i am checking a previous column value
    if (rowdata.Cells[5].Value=="XYZ")
    {  
          rowdata.Cells[6] = new DataGridViewTextBoxCell();
    }
}

This way you can dynamically render/ showing the control in the GridView in Winforms c#.

The above code simple update the cell with new cell. We can't remove button from the cell nor remove whole, so instead we can initial a new cell that will override the button visibility.

I am not sure if this will help but you can also consider using TableLayoutPanel.

Refer: Winforms TableLayoutPanel adding rows programmatically
