Using control from Essential Studio 14.4.0.15 with project references to control version 14.4451.0.15.
I've created a class with a couple of properties and bound a BindingList to a gridgroupingcontrol.
internal class GenericConfiguration : INotifyPropertyChanged
{
//Implement INotifyPropertyChanged so that GridGroupingControl
//in Configuration form can update the bound List<GenericConfiguration>.
public event PropertyChangedEventHandler PropertyChanged;
private dynamic _settingValue;
public string SettingName { get; set; }
public dynamic SettingValue
{
get { return _settingValue; }
set
{
bool bVal;
if (bool.TryParse(value, out bVal)) {
if (_settingValue != bVal) {
_settingValue = bVal;
RaisePropertyChanged();
}
}
else if (_settingValue != value) {
_settingValue = value;
RaisePropertyChanged();
}
}
}
public GenericConfiguration() {}
public GenericConfiguration(string Name, dynamic Value)
{
this.SettingName = Name;
_settingValue = Value;
}
void RaisePropertyChanged([CallerMemberName] string PropName = "")
{
PropertyChangedEventHandler handlerPC = PropertyChanged;
if (handlerPC != null) {
handlerPC(this, new PropertyChangedEventArgs(PropName));
}
}
}
I run my project and pull up the Configuration screen. When I try to edit a SettingValue cell, the value I had just typed is replaced by a null value after clicking another cell. I've tried looking for a solution here and elsewhere without success. I've even looked at a demo using this control from one of your knowledgebase articles. I've tried running tests with and without QueryCellStyleInfo event handler. Funny thing is that with the QueryCellStyleInfo event handler, the gridgroupingcontrol does pass the changed value on a cell with a dropdown but on a cell without a dropdown it passes 'null' (see pics at the bottom).
Below is the code for my Configuration form:
public partial class Configuration : Form
{
BindingList<GenericConfiguration> _lstSettings = new BindingList<GenericConfiguration>();
StringCollection _lstBools = new StringCollection { "true", "false" };
public Configuration()
{
InitializeComponent();
}
private void Configuration_Load(object sender, EventArgs e)
{
_lstSettings = Global.AppConfiguration.GetConfigDisplaySettingsListTest();
ggcSettings.DataSource = _lstSettings;
ggcSettings.ShowColumnHeaders = true;
ggcSettings.BackColor = Color.SandyBrown;
ggcSettings.TableOptions.ListBoxSelectionMode = SelectionMode.One;
}
private void ggcSettings_QueryCellStyleInfo(object Sender, GridTableCellStyleInfoEventArgs e)
{
Debug.Print("r: " + e.Style.TableCellIdentity.RowIndex + " c: " + e.Style.TableCellIdentity.ColIndex + " val: " + e.Style.CellValue);
//string d = "row: {0} col: {1} - {2}";
//Debug.Print(string.Format(d, e.TableCellIdentity.RowIndex, e.TableCellIdentity.ColIndex, e.Style.CellValue.ToString() + ""));
if (e.TableCellIdentity.RowIndex > 1)
{
if (e.TableCellIdentity.ColIndex == 1)
{
e.Style.Enabled = false;
}
if (e.TableCellIdentity.ColIndex == 2)
{
if (e.Style.CellValue != null)
if ((e.Style.CellValue.ToString() != ""))
{
if (_lstSettings[e.TableCellIdentity.RowIndex - 2].SettingValue.GetType() == typeof(Boolean))
{
e.Style.CellType = "ComboBox";
e.Style.ChoiceList = _lstBools;
e.Style.DropDownStyle = Syncfusion.Windows.Forms.Grid.GridDropDownStyle.AutoComplete;
e.Style.AutoCompleteInEditMode = Syncfusion.Windows.Forms.Grid.GridComboSelectionOptions.AutoComplete;
}
else
{
e.Style.CellType = "TextBox";
e.Style.ReadOnly = false;
}
}
}
}
}
}
Below are my testing pics when NOT using QueryCellStyleInfo handler:

Your help is much appreciated.
