How to set different background color for each column header in Xamarin.iOS DataGrid?
You can set different background color for each column header by customizing the GridColumn.HeaderTemplate in SfDataGrid.
Refer the below code in which an UILabel is loaded inside the header template of the columns and its background color is updated based on requirement.
For Auto generated columns:
public MyViewController()
{
dataGrid = new SfDataGrid();
sviewModel = new ViewModel();
dataGrid.ItemsSource = viewModel.OrdersInfo;
dataGrid.ColumnSizer = ColumnSizer.Star;
dataGrid.AutoGenerateColumns = true;
dataGrid.AutoGeneratingColumn += DataGrid_AutoGeneratingColumn;
this.View.AddSubview(dataGrid);
}
private void DataGrid_AutoGeneratingColumn(object sender, AutoGeneratingColumnArgs e)
{
if (e.Column.MappingName == "OrderID")
{
e.Column.HeaderTemplate = new UILabel()
{
Text = "OrderID",
BackgroundColor = UIColor.Gray,
TextAlignment=UITextAlignment.Center
};
}
else if (e.Column.MappingName == "CustomerID")
{
e.Column.HeaderTemplate = new UILabel()
{
Text = "CustomerID",
BackgroundColor = UIColor.Brown
TextAlignment=UITextAlignment.Center
};
}
else if (e.Column.MappingName == "Freight")
{
e.Column.HeaderTemplate = new UILabel()
{
Text = "Freight",
BackgroundColor = UIColor.Green
TextAlignment=UITextAlignment.Center
};
}
else if (e.Column.MappingName == "Country")
{
e.Column.HeaderTemplate = new UILabel()
{
Text = "Country",
BackgroundColor = UIColor.Red
TextAlignment=UITextAlignment.Center
};
}
}
public override void ViewDidLayoutSubviews()
{
base.ViewDidLayoutSubviews();
dataGrid.Frame = new CoreGraphics.CGRect(0, 20, this.View.Frame.Width, this.View.Frame.Height);
}
For Manually generated columns:
public MyViewController()
{
dataGrid = new SfDataGrid();
sviewModel = new ViewModel();
dataGrid.ItemsSource = viewModel.OrdersInfo;
dataGrid.ColumnSizer = ColumnSizer.Star;
dataGrid.AutoGenerateColumns = false;
dataGrid.Columns.Add(new GridTextColumn()
{
MappingName = "OrderID",
HeaderTemplate=new UILabel()
{
Text="OrderId",
BackgroundColor=UIColor.Gray,
TextAlignment=UITextAlignment.Center
}
};
dataGrid.Columns.Add(new GridTextColumn()
{
MappingName = " CustomerID ",
HeaderTemplate=new UILabel()
{
Text=" CustomerID ",
BackgroundColor=UIColor. Brown,
TextAlignment=UITextAlignment.Center
}
};
dataGrid.Columns.Add(new GridTextColumn()
{
MappingName = " Freight ",
HeaderTemplate=new UILabel()
{
Text=" Freight ",
BackgroundColor=UIColor. Green,
TextAlignment=UITextAlignment.Center
}
};
dataGrid.Columns.Add(new GridTextColumn()
{
MappingName = " Country ",
HeaderTemplate=new UILabel()
{
Text=" Country ",
BackgroundColor=UIColor. Red,
TextAlignment=UITextAlignment.Center
}
};
this.View.AddSubview(dataGrid);
}
public override void ViewDidLayoutSubviews()
{
base.ViewDidLayoutSubviews();
dataGrid.Frame = new CoreGraphics.CGRect(0, 20, this.View.Frame.Width, this.View.Frame.Height);
}
On executing the above code the below output will be obtained.
