Hi Kiran,

Thanks for your interest in Syncfusion Products.

You need to create a custom celltype as in the below sample which is shipped with the browser samples.

\\Syncfusion\EssentialStudio\5.1\Windows\Grid.Windows\Samples\2.0\CustomCellTypes\DropDownFormAndUserControlSample

A custom CellType requires a model class and a renderer class. The model class handles the serialization requirements for the control and creates the renderer class. The renderer class handles the UI requirements of the cell.

For GridGroupingControl, custom celltypes has to be registered through TableModel.CellModels.Add function.
Refer this shipped sample for more details
\\Syncfusion\Essential Studio\5.1\windows\Grid.Grouping.Windows\Samples\FeatureSamples\CustomCellTypes

Here is a sample in GridGroupingControl with CheckedListBox cells.

Have a nice time.

////Modified code in DropDownUserControl.cs

{
// closethe dropdown with a Done setting
if (this.CurrentCell.IsDroppedDown)
{
this.CurrentCell.IsModified = true;
this.Grid.CurrentCell.CloseDropDown(Syncfusion.Windows.Forms.PopupCloseType.Done);
}

}

Hi Haneef,
Thaks for the reply. I found refresh issue with Tab button click when dropdown is open. Pls find the sample attached below.

Steps to reproduce
1. Click on the DropDown button in a cell
2. Do some selection changes
3. Click Tab. The Dropdown closes & the selection is not changed in the cell. Click Tab again the cell Refreshes.
I need a fix or workaround for this.
Pls let me know

Thanks

Hi Kiran,

You would probably have to set the celltext using GridModel in DropDownContainerCloseDropDown override method. You could use code such as:

public override void DropDownContainerCloseDropDown(object sender, PopupClosedEventArgs e)
{
if (e.PopupCloseType != PopupCloseType.Canceled)
{
if (this.NotifyCurrentCellChanging())
{
ControlValue = this.ddCtrl.GetValuesToString();
this.ControlText = ControlValue.ToString();
this.Grid.Model[RowIndex, ColIndex].Text = this.ControlText;
this.NotifyCurrentCellChanged();
Grid.InvalidateRange(GridRangeInfo.Cell(RowIndex, ColIndex), GridRangeOptions.MergeCoveredCells); // Merge all cells
}
}
base.DropDownContainerCloseDropDown(sender, e);
}

Best regards,
