GridviewComboboxColumn selectindexchange

Hi,
we are developing with Telerik Winforms controls Q3 2007.
We are trying to get the event inside GridviewComboboxColumn when selected index or selected value is changed, but we can't get this event.
We guess it must be so easy that we think it must be in front of us, but we can't see it... it's we drive us crazy.

Please, someone can help us.

Thanks in advance

GridView CurrentPosition after Sort

I've either found a bug in the RadGridView or I'm using the wrong collection.

I am leveraging the MasterTemplate.DataView.CurrentPosition in order to capture the index of the selected item, which I'm placing in a form-level variable. When this item is deleted, I want the CurrentPosition so that I can highlight the next row at that same index.

The CurrentPosition works fantastic in all instances, save for when the column is Sorted. I tried grabbing the CurrentPosition both in the SortChanged() and SortChanging() events, but the CurrentPosition property does not reflect the new location of the selected row after the sort.

I tried to circumvent this by a combination of .Refresh and <grid dataview>.IndexOf(<grid dataview>.CurrentItem), but this didn't work.

FYI: The reason I used the MasterTemplate.DataView is because this also takes into account Filtering.

Anyone's feedback would be greatly appreciated!

Saving Multiple RadGridViews

Hello All,

Is it possible to save multiple RadGridViews to the same file with their data included?

The SaveLayout/LoadLayout functions only work with the layout, and, as far as I can tell, do not provide functionality to save multiple grids to the same file.

Thanks!

Rad grid relation problem

Hi there,

Iam using a radgrid for that we are creating Parent-child relation programatically.It works fine for the first time (refer screen shot1) when loading. But if we have done any update operation or if we are again trying to load the page.It is creating multiple tables in the Child grid view(refer screen shot 2).We are calling that creating relation method again in Update operation if it is not called the changes done are not reflecting in the child grid.Here is the code how we are programatically binding.

radGrid_MultiplePI.DataSource = Nothing

Dim ds1 As New DataSet()

Dim ds2 As New DataSet()

ds1 = objdalProtocolSetupWizard.displayProtocolandInstitutions(cmbProtocolNumber.SelectedValue)

Me.radGrid_MultiplePI.MasterGridViewTemplate.DataSource = Nothing

Me.radGrid_MultiplePI.MasterGridViewTemplate.AllowAddNewRow = False

Me.radGrid_MultiplePI.MasterGridViewTemplate.AllowDeleteRow = False

radGrid_MultiplePI.DataSource = ds1.Tables("Institutions")

radGrid_MultiplePI.Columns(1).IsVisible = False

radGrid_MultiplePI.Columns(1).Width = 150

radGrid_MultiplePI.Columns(2).Width = 150

Dim template As New GridViewTemplate()

template.BeginInit()

template.DataSource = Nothing

radGrid_MultiplePI.MasterGridViewTemplate.ChildGridViewTemplates.Insert(0, template)

template.AllowAddNewRow = False

template.AllowEditRow = False

template.AllowDeleteRow = False

template.DataSource = ds1.Tables("Investigators")

Dim relation As New GridViewRelation(radGrid_MultiplePI.MasterGridViewTemplate)

relation.ChildTemplate = template

relation.RelationName = "InstitutionInvestigators"

relation.ParentColumnNames.Add("ID")

relation.ChildColumnNames.Add("ID")

template.Columns(0).Width = 100

template.Columns(1).Width = 100

template.Columns(0).IsVisible = False

radGrid_MultiplePI.Relations.Add(relation)

template.EndInit()

radGrid_MultiplePI.Refresh()

Production release is scheduled very soon it's need to be resolved asap.Looking forward for your reply.

Thanks,
Prasad

Special Days + previous month's days

Ok, I'm not sure how to explain this, but, I have a list of "Special Days" that span 2 weeks on both sides of the displayed calendar.

For days that are "vacation" the image shown is the plane. However if the last days of the previous month is also a vacation day. The images do not show up. (See image attached).

Any work around for this?

Thanks!!
