Thanks for getting back to me on this. I went back and looked at my initial post and noticed that it doesn't really explain the problem. I apologize for the terrible explanation. Let me try it again.

First off, the black boxes in the screenshot were only there to hide sensitive data from this post. It's not actually there in real life. I modified your sample to show what I'm talking about. When you run the example, notice that Row12 is partially visible at the bottom of the grid. When you try to double click that row, Row 13 is scrolled into view. The row on e.Row in the event handler is Row13, not Row 12 as you intended to double click. In reality, 1 click was on Row12 and the other was on Row13. We had the situation where users were thinking they were double clicking one row to open a record and they were getting an entirely different record due to this behavior.

I wrote some hack code to prevent them from selecting a row that wasn't entirely in view as a work around.

Thanks,
Stephen

Hi Georgi,

I am waiting for your reply..

I am using same code in my application . I don't see any partial visible rows but when I click last fully visible rows , next row is under the mouse.

Here is my code with hyperlink in my grid.

Public Sub AfterCreateChildElements(ByVal parent As Infragistics.Win.UIElement) Implements Infragistics.Win.IUIElementCreationFilter.AfterCreateChildElements

If TypeOf parent Is HeaderUIElement Then

Dim aColHeader As ColumnHeader

aColHeader = CType(parent, HeaderUIElement).Header

If aColHeader.Column.Key = oKey Then

Dim aTextUIElement As TextUIElement

Dim aCheckBoxUIElement As CheckBoxUIElement

aCheckBoxUIElement = parent.GetDescendant(GetType(CheckBoxUIElement))

If aCheckBoxUIElement Is Nothing Then

aCheckBoxUIElement = New CheckBoxUIElement(parent)

End If

aTextUIElement = CType(parent.GetDescendant(GetType(TextUIElement)), TextUIElement)

If aTextUIElement Is Nothing Then Exit Sub 

Dim aheader As ColumnHeader = CType(aCheckBoxUIElement.GetAncestor(GetType(HeaderUIElement)).GetContext(GetType(ColumnHeader)), ColumnHeader)

If aheader.Tag Is Nothing Then

If oCheckState Then

aheader.Tag = Windows.Forms.CheckState.Indeterminate

Else

aheader.Tag = oCheckState

End If

Else

aCheckBoxUIElement.CheckState = CType(aheader.Tag, Windows.Forms.CheckState)

End If

AddHandler aCheckBoxUIElement.ElementClick, AddressOf aCheckBoxUIElement_ElementClick

parent.ChildElements.Add(aCheckBoxUIElement)

aCheckBoxUIElement.Rect = New System.Drawing.Rectangle(parent.Rect.X + 6, parent.Rect.Y + ((parent.Rect.Height - aCheckBoxUIElement.CheckSize.Height) / 2), aCheckBoxUIElement.CheckSize.Width, aCheckBoxUIElement.CheckSize.Height)

aTextUIElement.Rect = New System.Drawing.Rectangle(aCheckBoxUIElement.Rect.Right + 3, aTextUIElement.Rect.Y, parent.Rect.Width - (aCheckBoxUIElement.Rect.Right - parent.Rect.X), aTextUIElement.Rect.Height)

Else

Dim aCheckBoxUIElement As CheckBoxUIElement

aCheckBoxUIElement = parent.GetDescendant(GetType(CheckBoxUIElement))

If Not aCheckBoxUIElement Is Nothing Then

parent.ChildElements.Remove(aCheckBoxUIElement)

aCheckBoxUIElement.Dispose()

End If

End If

End If

If TypeOf parent Is RowColRegionIntersectionUIElement Then

If TypeOf parent Is RowColRegionIntersectionUIElement Then

Dim elementsToRemove As New List(Of UIElement)()

Dim elementsToIncrease As New List(Of UIElement)()

For Each rowUIElement As RowUIElement In parent.ChildElements.OfType(Of RowUIElement)()

If rowUIElement.Rect.Bottom > parent.Rect.Bottom Then

elementsToIncrease.Add(prevRowUIElement)

elementsToRemove.Add(rowUIElement)

AddHeight = parent.Rect.Bottom - prevRowUIElement.Rect.Bottom

Continue For

Else

prevRowUIElement = rowUIElement

rowUIElement.Row.Height = 20

End If

Next

For Each element As UIElement In elementsToRemove

parent.ChildElements.Remove(element)

Next

For Each element As RowUIElement In elementsToIncrease

element.Row.Height = element.Row.Height + AddHeight

Next

End If

If TypeOf parent Is CellUIElement Then

parent.Rect = New Drawing.Rectangle(parent.Rect.X, parent.Rect.Y, parent.Rect.Width, parent.Parent.Rect.Height - 1)

End If

End If

End Sub

Thanks for our reply.

I was looking sample which one is provided by Chris because we have same issue which is mentioned in this forum.

but in this sample when I click on last partial visible rows it's considering last two rows.

It's so confusing.

Can you please explain it and provide me a solution for it?

Thanks

Hi,

Could you please modify my sample to reproduce your scenario and issue and I`ll be glad to research it for you.

Let me know if you have any questions.
