So, i can create Button such:

Button Button = new Button();
Button.Text = "Active";
Button.Width = 100;
Button.Height = 30;

And i can not add object Button to row = new string[] {obj.CardInfo, start_day, end_day, execute_day, obj.Username, obj.Mobile, Id_User, Button }; Because it is string row. I hope you are undestand me

Are you trying to add a button to each row of the datagrid?

Solution 1

You can add the column with that :

C#

dataGridView1.Columns.Add(new DataGridViewButtonColumn()
                {
                Name="ColumnName",
                HeaderText="Header"
                // add here properties for the new column
                }
             );

I need add one column, but at loop i want add last row with button.

[no name] 17-Apr-13 5:45am

ListCards.ColumnCount = 8;
Button Button = new Button();
Button.Text = "Active";
Button.Width = 100;
Button.Height = 30;

foreach (var obj in BLL.Cards.GetListCards())
{
object row = new object[] { obj.CardInfo, obj.StartDay, obj.EndDay, obj.ExicuteDay, obj.IdUser, obj.Username, obj.Status, Button };
ListCards.Rows.Add(row);

}

But is wrong

Thomas Barbare 17-Apr-13 5:47am

You wants the button only on the last row, right ?

[no name] 17-Apr-13 5:53am

Again! i have 3 columns: Name, Ststus, Action.
After i form row, that add to Datagrid.
For column Name and Status i from row as: string[] row = new string[] {obj.CardInfo, start_day, end_day }
Attention: and last field for every row must be Button
In result i must get table view:

Name Status Action
Ol 1 Button1
PO 2 Button2

[no name] 17-Apr-13 5:54am

All this i must do at loop, where i form rows and add it

[no name] 17-Apr-13 6:01am

My last code:
object row = new object();
foreach (var obj in BLL.Cards.GetListCards())
{
object[] row = {Button, obj.CardInfo, obj.StartDay, obj.EndDay, obj.ExicuteDay, obj.IdUser, obj.Username};

ListCards.Rows.Add(row);

}

It code gives me Grid, but at column Status i see not button: System.Windows.Form.Button

Thomas Barbare 17-Apr-13 6:06am

When you have populate the grid with your strings do this foreach loop :

foreach (DataGridViewRow item in ListCards.Rows)
{
item.Cells[8] = new DataGridViewButtonCell(){
Value = "text of the button"
};
}

Thomas Barbare 17-Apr-13 6:08am

well 'item.Cells[8]' change 8 with your Column index or name of the future button

[no name] 17-Apr-13 6:13am

ouuuuuu Thank you very much. It works!!! How i can get value every cells here at loop? And if value = 1 - to make background button?

Thomas Barbare 17-Apr-13 6:22am

I don't see what you means by background button but I think you want to change properties of the newly created button, you can with that :

foreach (DataGridViewRow item in dataGridView1.Rows)
{
if (item.Cells["yourStatusColumn"].Value == "1")
{
item.Cells["ColumnName"] = new DataGridViewButtonCell()
{
Value = "1" //or whatever you wants
};
}
else
{
item.Cells["ColumnName"] = new DataGridViewButtonCell()
{
Value = "not 1" //or whatever you wants
};
}
}

You can replace the if/else by a switch of item.Cells["yourStatusColumn"].Value if you are more value to check.

[no name] 17-Apr-13 7:07am

Thank you. And how insted Value = "1" change background image button?

[no name] 17-Apr-13 7:28am

I made such:

DataGridViewImageColumn imageColumn;

foreach (DataGridViewRow item in ListCards.Rows)
{
if (item.Cells["Status"].Value == "1")
{

imageColumn = new DataGridViewImageColumn();
imageColumn.Image = Cards.Properties.Resources.Active;
ListCards.Columns.Add(imageColumn);
}
else
{

imageColumn = new DataGridViewImageColumn();
imageColumn.Image = Cards.Properties.Resources.Add;
ListCards.Columns.Add(imageColumn);

}
}

But i can not insert button image instead item.Cells["ColumnName"] how it made you. Can you show me, please?

[no name] 17-Apr-13 7:30am

Ou, no, my example is not correctly

Thomas Barbare 17-Apr-13 8:08am

If you wants an image instead of a button just create a new column with type DataGridViewImage and do that :

foreach (DataGridViewRow item in dataGridView1.Rows)
{
if (item.Cells[0].Value.ToString() == "1")
{
item.Cells[1] = new DataGridViewImageCell()
{
Value=new Bitmap("test.png") //for my exemple I load an external img

};
}
else
{
item.Cells[1] = new DataGridViewImageCell()
{
Value=new Bitmap("image2.png")
};
}
}

[no name] 17-Apr-13 9:31am

Here display me error: Parameter is not valid.

item.Cells[1] = new DataGridViewImageCell()
{
Value = new Bitmap("image2.png")
};

What is path to image? Can i specify resourse?

Thomas Barbare 17-Apr-13 9:37am

Yes. The path is ..\debug\image2.png

[no name] 17-Apr-13 11:03am

So, get error too - Here display me error: Parameter is not valid.
