How to edit a column in Xamarin.Android DataGrid?
Currently SfDatagrid does not directly support editing of GridCells. However if your requirement is to edit the text of the GridCells during runtime, SfDataGrid allows you to achieve this by creating a custom GridCell derived from GridCell. You can load an editable control inside the GridCell from the sample. The edited values can be committed in the the TextChanged event handler of the EditText class.
Refer the following code example to edit the text of GridCell in runtime.
public class CustomGridCell: GridCell
{
private EditText editText;
public CustomGridCell(Context ctxt) : base (ctxt)
{
editText = new EditText(ctxt);
editText.TextChanged += editText_TextChanged;
editText.SetTextColor(Color.Black);
CanRenderUnLoad = false;
this.AddView(editText);
}
public void editText_TextChanged(object sender, TextChangedEventArgs e)
{
DataColumn.Renderer.DataGrid.View.GetItemProperties().
SetValue(DataColumn.RowData,e.Text.ToString(), DataColumn.GridColumn.MappingName);
}
protected override void OnLayout(bool changed, int left, int top, int right, int bottom)
{
editText.Layout(0, 0, this.Width, this.Height);
}
protected override void OnDraw(Canvas canvas)
{
base.OnDraw(canvas);
if (DataColumn.CellValue != null && editText.Text != DataColumn.CellValue.ToString())
editText.Text = (DataColumn.CellValue.ToString());
}
protected override void UnLoad()
{
if (this.Parent != null)
(this.Parent as VirtualizingCellsControl).RemoveView(this);
}
}
The following screenshots shows the final outcome when the above code is executed.
