Ajaxified Radgrid pager posts back twice on page index change (Randomly)

Hi

I have created a simple ajaxified radgrid. Everything works fine except that sometimes when I paginate (change page index), it triggers the OnCommand client event twice. And that too randomly. There is no fixed index at which it happens and that makes it even more difficult for me to identify the problem. For example if it happens when I click page 5, there are 2 postbacks.... the first one passes the correct pageIndex (4) and loads the proper data on the grid.... but the second post back passes pageIndex as 0 so the grid displays page 1 data.

My pagesize is 10 and I have more than 100 pages.

Here is my Aspx:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default3.aspx.vb" Inherits="Default3" %>

Using dc As New DataClassesDataContext

End If

data.Add("Data", EL.Skip(startIndex * maximumRows).Take(maximumRows).ToList())

data.Add("Count", EL.Count)

Return data

End Using

End Function

End Class

P.S: I am using v2011.2.915.35 of Telerik and this happens both in Firefox and IE.

MonthYear picker

I want to replace my RadDatePicker with a RadMonthYearPicker resulting in less clutter for the page, problem is I need to get the start and end of the month selected via MonthYear picker for my query.

the statement below:

protected void DateChange(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)

{

//Session.Add("StartDate", RadDatePicker1.SelectedDate);

Session.Add("selectedMonth", RadMonthYearPicker1.DbSelectedDate);

}

returns merely the month I choose, the day today, and the chosen year. ex return '5/13/2011'. When I want to get '5/1/2011' and '5/31/2011'
Any suggestions on how I can get the 'start' and 'end' of the month or do I stick with RadDatePicker for now? If there is a way to do this pointing me in the right direction would be much appreciated.

Thanks

Validation on GridDateTimeColumn

I am trying to programmatically add a RequiredFieldValidator to a GridDateTimeColumn. However, I get a null reference exception when the grid goes into Edit or Insert mode.

Relevant code is:

                <telerik:GridDateTimeColumn DataField="NoticeDate" HeaderText="Notice Date" UniqueName="NoticeDate"
                    DataFormatString="{0:d}" />

   Private Sub grdNip_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles grdNip.ItemCreated
        If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
            Dim item As GridEditableItem = e.Item

            Dim dateEditor As GridDateTimeColumnEditor
            Dim valRequired As RequiredFieldValidator
            Dim cell As TableCell

            dateEditor = item.EditManager.GetColumnEditor("NoticeDate")
            cell = dateEditor.PickerControl.Parent
            dateEditor.PickerControl.ID = "dtNoticeDate"
            valRequired = New RequiredFieldValidator()
            valRequired.ControlToValidate = "dtNoticeDate"
            valRequired.ErrorMessage = "Notice date is required"
            cell.Controls.Add(valRequired)
        End If
    End Sub

Unable to get value selected in one Radcombobox to OnItemsRequested event of the another RadComboxbox

There are two RadComboBox in RadGrid. I need to filter the list of one combobox based on the selected value of the other RadComboBox..
If there is any solution to this problem kindly post as soon as possible.

The code that i have written on OnItemsRequested event of dependant RadComboBox is

List<Item> oItemList = null;

RadComboBox ddlItemName = (RadComboBox)sender;

Item oItem = new Item();

GridDataItem oGridDataItem = (GridDataItem)ddlItemName.Parent.Parent;

if (!string.IsNullOrEmpty(e.Text))

{

oItem.ItemName = e.Text;

if (oGridDataItem != null)

{

RadComboBox ddlMake = (RadComboBox)oGridDataItem.FindControl("ddlMake");

if (ddlMake != null && !string.IsNullOrEmpty(ddlMake.SelectedValue))

oItem.MakeId = Convert.ToInt64(ddlMake.SelectedValue);

Radgrid Footer static fixed

Hello,

how can i config the paging-bar in fixed mode?
the problem is, when i grouping the items, the paging-footer is align on the last column and when i open the last grouping item, then i can not see the child-items.
but when i resize the ie-window, the paging footer is going to bottom.
is this a bug?

and the second is, i config the pagingstyle position = top, but the paging is ever on buttom.

update: now i see, this is not a paging problem, because i disable the paging "alwaysvisible = false" and i have the same problem with the radgrid-footer. see attachment.

update2: the problem is the scrollbar. how i can config the scrollbar she is ever on buttom?
