001.png: On the GridViewComboBoxColumn how do I prevent the drop down from covering the input cell when grid is at the bottom of the screen's viewable area?
I've tried setting the position and location under the CellEditorInitialized event, but had no luck.
private void RadGridARCashReceipt_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
if (e.ActiveEditor is RadDropDownListEditor)
{
RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;
if (editor != null)
{
RadDropDownListEditorElement ddlElement = (RadDropDownListEditorElement)editor.EditorElement;
ddlElement.EnableMouseWheel = false;
ddlElement.DropDownMinSize = new Size(200, 200);
ddlElement.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(200, 200);
//ddlElement.AutoCompleteSuggest.DropDownList.Location = new Point(1000, 1000);
}
}
}
Hello, Paito,
Thank you for the provided clarification.
With the following changes I was able to replicate the undesired overlapping of the autocomplete popup with the editable area. The attached AutoCompleteDropDown.gif illustrates the incorrect behavior:
this.radGridView1.DataSource = this.productsBindingSource;
GridViewComboBoxColumn combCol = new GridViewComboBoxColumn("Category");
combCol.DataSource = this.categoriesBindingSource;
combCol.ValueMember = "CategoryID";
combCol.DisplayMember = "CategoryName";
combCol.FieldName = "CategoryID";
combCol.DropDownStyle = RadDropDownStyle.DropDown;
combCol.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
combCol.Width = 200;
this.radGridView1.Columns.Insert(0,combCol);
this.radGridView1.AddNewRowPosition = SystemRowPosition.Bottom;

I have also updated your Telerik points.
Currently, the possible solution that I can suggest is to use the following custom implementation for the AutoCompleteSuggestHelper:
public RadForm1()
{
InitializeComponent();
this.radGridView1.CellEditorInitialized += RadGridView1_CellEditorInitialized;
}
private void RadGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
RadDropDownListEditor ddl = e.ActiveEditor as RadDropDownListEditor;
if (ddl!=null)
{
RadDropDownListEditorElement el = ddl.EditorElement as RadDropDownListEditorElement;
el.AutoCompleteSuggest = new CustomAutoCompleteSuggestHelper(el);
}
}
public class CustomAutoCompleteSuggestHelper : AutoCompleteSuggestHelper
{
public CustomAutoCompleteSuggestHelper(RadDropDownListElement owner) : base(owner)
{
}
protected override RadDropDownListElement CreateDropDownElement()
{
return new CustomAutoCompleteSuggestDropDownListElement(this);
}
}
public class CustomAutoCompleteSuggestDropDownListElement : AutoCompleteSuggestDropDownListElement
{
private AutoCompleteSuggestHelper owner;
public CustomAutoCompleteSuggestDropDownListElement(AutoCompleteSuggestHelper owner) : base(owner)
{
this.owner = owner;
}
protected override Point GetPopupLocation(RadPopupControlBase popup)
{
Point ddlLocation = this.owner.Owner.ControlBoundingRectangle.Location;
Point screenLocation = this.owner.Owner.ElementTree.Control.PointToScreen(ddlLocation);
int screenHeight = Screen.PrimaryScreen.WorkingArea.Height;
if (screenHeight > screenLocation.Y + popup.Height + this.owner.Owner.ControlBoundingRectangle.Height)
{
screenLocation.Y += this.owner.Owner.ControlBoundingRectangle.Height;
}
return screenLocation;
}
}The provided DropDownFixedLocation.gif demonstrates the achieved result.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
