AutoCompleteBox: CustomTextBlock example incomplete

In the example listed at http://www.telerik.com/help/winforms/editors-autocompletetextbox-creating-custom-blocks.html . At the very bottom you have some code for

radAutoCompleteBox1.TextBlockFormatting += new TextBlockFormattingEventHandler(radAutoCompleteBox1_TextBlockFormatting);

this.radAutoCompleteBox1.Text = "Euro;USD;GBP;";

Only new textblocks created are formatted with the new style. These 3 text blocks 'Euro' 'USD' and 'GBP' are in the old format. The TextBlockFormatting code is not listed.

I need this to finish up my custom TextBlock.

Thanks

[Solved] Color Ragdrid row at will without Row or Cell Formatting Event Handler

I would like to change the BackColor a datagridview row. While searching around it 's clear that I will have to access the GridDataRowElement or GridDataCellElement to do it. From that after creating a variable of the type we can call something RowElement.BackColor = Color.Gray or CellElement.BackColor = Color.Gray

I have already tried this but it only colors row while the mouse is hovering at it (very strange...)

Dim rwInfo As GridViewRowInfo = myGrid.Rows(i)

myGrid.GridViewElement.TableElement.GetRowElement(rwInfo).BackColor = System.Drawing.Color.PaleGoldenrod

Now with the code below as a pointer, my problem is that I'm trying to cast a gridview row as GridDataRowElement it always results in epic failure.

For i = 0 To m

yGrid.Rows.Count - 1

Dim r As

GridViewRowInfo = myGrid.Rows(i)

Dim rwInfo As

GridViewRowInfo = myGrid.Rows(i)

For Each cInfo As GridViewCellInfo In

rwInfo.Cells

Dim row As

GridDataRowElement = TryCast(myGrid.Rows(i), GridDataRowElement)

 	For Each c In myGrid.Columns

Dim cell As GridDataCellElement = CType

(rwInfo.Cells(c.Index), GridDataCellElement)

Next
Next

Could someone please point me to the right direction on how this can be done?

Thanks

Resource vs Column width calculation

The width of a resource does not always match the column(s) underneath it, resulting in the resources shifting to the left in relation to the column(s) below. It appears to be about 1 pixel difference per resource which becomes more noticeable with multiple resources . I looks like some sort of difference in rounding when calculating available space, because if you gradually resize the form the resources will come close to matching the column(s) before jumping back to the full difference again. This issue can be demonstrated in the Scheduler->Grouping demo if you gradually resize the form, however as there are only 2 resources, the issue is hard to spot, but it is there.

Screen Location of Floating Window

I need to find the absolute screen coordinates of a floating dockwindow from within code running inside a form hosted inside this dockwindow. I have tried different things but all I get back is the screen location of the original form that the rad dock control is hosted.

Any ideas how I can achieve this?

Regards,

George

[Solved] AutoCompleteBox: Determine if text came from AutoCompleteItems

Hey Telerik!

I would like to determine if a newly created text block was from the autocompleteitems list or not.

I noticed that your AutoCompleteItems used a RadListDataItemCollection. Is it possible to use a collection of objects ?

If not, I will be adding items to the AutoCompleteItems in the form of

items.Add(New RadListDataItem("Joe Smith", "GUID HERE"))

I was assuming the CreateTextBlock event could be used to determine if there was a GUID value attached or not. I could use this as a way to determine if the item was from the AutoCompleteItems. I am not sure how to get the data value for the text block element or hopefully custom class for the newly created block.

Thanks

Zooming Images

I want to show thumbnail images in a ListView in IconView. I got the thumbnail images in a fixed size and I want to show them smaller. I set the image property of the listviewdataitem to the thumbnail and the Itemsize property of the listview to a size smaller than the thumbnails. Now I only see a part of the thumbnail in the listviewdataitems. Can I zoom the images to see the whole image in the listviewdataitem?
Thanks in advance!

Advanced GridViewColumnGroup?

Hi, I have a very special requirement to address.

I'm looking to manipulate the RadGridView to some sort of PivotTable, but I need to edit the objects that the grid will be bound to (would be great to run in bound mode), and by edit I mean drag and drop the 'Projects' to different weeks of months (but that's another problem).

My current problem is about altering the UI of the grid, so that it can be more intuitive for the user and also easier to maintain.

Please see the screenshots in attachment to understand my goal.

Thanks,
