RadDataPager Recognizing returns null in some conditions

hi my dear friends :
i have a radcombobox that is in relationship with RadListViw (with RadDataPager Inside)...
when i change the item of rad combobox , so RadListView is Updated... -> selectedIndexxhanged() server-side event...
-------------------------------------------------------------------------------------------------------------------------------------------------------------
my selectedIndexChanged() is like this :

protected void RadcbImagesGroup_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

rlvImages.DataBind();

var raddatapager = (rlvImages).FindControl("RadDataPager1") as RadDataPager;

if (raddatapager != null)

{

raddatapager.FireCommand("Page","First");

}

my radComboBox Item values is like : 1,2,3...

in mode 1 we have 25 pages...
in mode 2 we have 5 pages...
in mode 3 we have 5 pages...

my problem is when we are in mode 1 and put the pageNumber to more than 5 and when i change the combobox Item to mode 2 so



var raddatapager = (rlvImages).FindControl(

"RadDataPager1") as RadDataPager; is null...

but if we put the page# (we are in mode 1) to lower than 5 or equal 5 , and change the radcb item to another everything works fine...

where is the null problem?

thanks for advance

foreach (GridDataItem data in rgQuotes.MasterTableView.GetItems(GridItemType.Item))

{

Label lblStatus = (Label)data.FindControl("lblCredit");

Label lblQuoteApprove = (Label)data.FindControl("lblFinance");

lblStatus.Visible = false;

lblQuoteApprove.Visible = false;

}

rgQuotes.ExportSettings.ExportOnlyData = true;

rgQuotes.ExportSettings.IgnorePaging = true;

rgQuotes.ExportSettings.FileName = "Quotes";

rgQuotes.MasterTableView.ExportToExcel();

}

catch (Exception ex)

{

CommonFunctions.AddErrorLog("Sales=>Quotes", "btnExcel_Click", ex);

}

//Export the data in excel file format

}

While we switched over to FF then Images wont be exported to Excel sheet.

My columns are not only Treelistbound columns but also TreeListTemplateColumn and when I add them and load page it's seem fine, but when I do anything (load next page, refresh by button..etc) I show error "ERROR:Invalid column type: "TreeListTemplateColumn"."
Please Try again!

CheckBox within a Radgrid Template Column?

Hi,

I am trying to use a data bound Checkbox in a RadGrid Template Column but have come across several problems.
Firstly, i was trying to use the asp checkbox control. This works for displaying the existing data from my database but i get a DBnull error when i try to insert a new record.
So i tried to resolve this error by trying to capture the DBNull with a CheckNull function:

Public Function CheckNull(ByVal val As Object) As Boolean

If val.GetType Is DBNull.Value.GetType Then

Return False

Else

Return Convert.ToBoolean(val)

End If

End Function

but this didn't work. I then tried a custom CheckBox which overrides the DBNull error but this didn't fix the problem either

Public Class CustomCheckBox

Inherits Web.UI.WebControls.CheckBox

Public Property CheckedOverride() As Object

Get

Return MyBase.Checked

End Get

Set(ByVal value As Object)

If IsDBNull(value) Then

MyBase.Checked = False

ElseIf value.GetType() = GetType(Boolean) Then

MyBase.Checked = value

Else

MyBase.Checked = False

End If

End Set

End Property

End Class

I then searched the Telerik forums for a solution & came across the telerik:GridCheckBoxColumn (from this site http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/alleditablecolumns/defaultcs.aspx) BUT i do not have this available to me! When i enter this control i get an error saying it does not exist.

Is this an old control item which has been phased out or should it still be available to me on the latest version of Telerik controls?

if it isn't available then can you provide an alternative solution for the databound checkbox which is causing a DBnull conversion error?

Regards,

Shuja

Prevent Detail table from expanding

I have a grid which uses grouping on the top-level table and also has a detail table. it seems that, when a group is collapsed, and then expanded, then the detail table is expanded for all items in the group. Is there a way to prevent the detail table from being expanded when the user expands a group? The detail table should only be expanded when the user clicks on the expand/collapse column for the item in the master table.
