Select New Row

Hello

How can I realize this behavior? The user clicks to the first cell of the new row at the top of the grid. He fills in a value, then he presses the tab key. The cursor goes through the cells. When the user presses tab in the last cell, the row should be added and the cursor should go to the first cell of a new row.
This does not work for me: http://www.telerik.com/community/forums/winforms/gridview/automatically-add-new-row.aspx

Thank you

[Solved] Problem while updating the Cell from Item Template of Herarchical Grid.

Hello,

I am using Radgrid.

i am adding two columns in gridview master template

With gridViewChecklistItems.MasterTemplate.Columns

.Add(colChkListItemGroupID)

.Add(colChkListtemGroupName)

End With

i have added on template in Master template and adding some columns in it.

gridViewChecklistItems.MasterTemplate.Templates.Clear()

Dim itemsTemplate As GridViewTemplate = New GridViewTemplate

With itemsTemplate.Columns

.Add(colChklistHeadingID)

.Add(colChklistItemID)

.Add(colChklistItemName)

.Add(colChklistItemNote)

.Add(colChkItemTypeName)

.Add(colChkItemTypeSize)

End With

itemsTemplate.DataSource = gridListOfItems

gridViewChecklistItems.MasterTemplate.Templates.Add(itemsTemplate)

and also added the relation with master template colum and child template column

Dim itemToGroupRelation As GridViewRelation = New GridViewRelation(gridViewChecklistItems.MasterTemplate)

With itemToGroupRelation

.ChildTemplate = itemsTemplate

.RelationName = "GroupItems"

.ParentColumnNames.Add("ChecklistHeadingID")

.ChildColumnNames.Add("ChecklistHeadingID")

End With

gridViewChecklistItems.Relations.Add(itemToGroupRelation)

when i try to update the cell from mastertemplate column. the updated value in cell persists and also update the database
here i am using gridViewChecklistItems_CellValidating event to update the database. so its working fine.

now when i expand the item template/ child grid of specific row and update any sepecific cell,
the updated cell value does not persist in the Cell when i click on other cell or loose the focus from cell.
what would be the problem??.but the "gridViewChecklistItems_CellValidating" event is
fired and database is updated.

again one thing
when i update the one cell or more from itemtemplate. the event must be fired only once not for the cells
how to??

Thanks!

Exception during custom sorting 2010 Q2 SP2.

Hi

2010 Q2 SP2.

I have random exception when I want sort in grid.

I do something wrong or there is bug in grid?

In my scenario I do custom sorting:

private void radGridView1_CustomSorting(object sender, GridViewCustomSortingEventArgs e)

{

if (e.Column.Name == "Size")

{

SizeObject size1 = e.CellValue1 as SizeObject;

SizeObject size2 = e.CellValue2 as SizeObject;

if (size1.Size > size2.Size)

{ e.SortResult = 1; }

else if (size1.Size < size2.Size)

{ e.SortResult = -1; }

else

{ e.SortResult = 0; }

}

if (e.Column.SortOrder == RadSortOrder.Descending)

{ e.SortResult *= -1; }

}

ArgumentException - Insufficient space in the target location to copy the information.

[Solved] See all column content

I have a RadGridView with 3 columns.
One of the columns it's the full path of one file.
My problem is, when the file has a big full path, can't see it all because when i resize the column, it has a limit, the Control size.
Is there a way to add a horizontal scroll bar and allow me to resize one column with no limitation?

In attachment is one print of my problem.
