Updating user control in a grid with AJAX

Hi,
I have a user control in a grid which I want to update via ajax.
Scenario: I click on this link which is part of a user control. A pop up window opens up. I enter some details and save it and close pop up. Since the pop is the detailed version of the user control, now, as soon as the link closes I have a way to make the ajax call and identify the user control and update itself from Db. Right now I can get reference of the control and update it but it does not refresh on UI.Is there anything I am doing wrong here is relevant code..
AjaxManager_AjaxRequest gets called and reference to user control as well but it does not refresh on UI. in code it does get updated by grabbing new values from database. Any ideas..?

Custom PageSizeComboBox in Hierarchy not firing

I have a radgrid on my page that I create in the Page_Init. It has the MasterTableView along with a hierarchy setup call 'SubCodes'.

In my RadGrid1_ItemDataBound I am customizing the PageSizeComboBox for both the MasterTableView and SubCodes.

Public Sub RadGrid1_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

If (TypeOf (e.Item) Is GridPagerItem) And e.Item.OwnerTableView.Name <> "SubCodes" Then

Dim dropDown = DirectCast(e.Item.FindControl("PageSizeComboBox"), RadComboBox)

dropDown.Items.Clear()

dropDown.Items.Add(New RadComboBoxItem("10"))

dropDown.FindItemByText("10").Attributes.Add("ownerTableViewId", RadGrid1.MasterTableView.ClientID)

dropDown.Items.Add(New RadComboBoxItem("20"))

dropDown.FindItemByText("20").Attributes.Add("ownerTableViewId", RadGrid1.MasterTableView.ClientID)

dropDown.Items.Add(New RadComboBoxItem("50"))

dropDown.FindItemByText("50").Attributes.Add("ownerTableViewId", RadGrid1.MasterTableView.ClientID)

dropDown.Items.Add(New RadComboBoxItem("100"))

dropDown.FindItemByText("100").Attributes.Add("ownerTableViewId", RadGrid1.MasterTableView.ClientID)

dropDown.FindItemByText(e.Item.OwnerTableView.PageSize.ToString()).Selected = True

End If

If (TypeOf (e.Item) Is GridPagerItem) And e.Item.OwnerTableView.Name = "SubCodes" Then

Dim dropDown = DirectCast(e.Item.FindControl("PageSizeComboBox"), RadComboBox)

dropDown.Items.Clear()

dropDown.Items.Add(New RadComboBoxItem("1"))

dropDown.FindItemByText("1").Attributes.Add("ownerTableViewId", e.Item.ClientID)

dropDown.Items.Add(New RadComboBoxItem("2"))

dropDown.FindItemByText("2").Attributes.Add("ownerTableViewId", e.Item.ClientID)

dropDown.Items.Add(New RadComboBoxItem("5"))

dropDown.FindItemByText("5").Attributes.Add("ownerTableViewId", e.Item.ClientID)

dropDown.Items.Add(New RadComboBoxItem("10"))

dropDown.FindItemByText("10").Attributes.Add("ownerTableViewId", e.Item.ClientID)

dropDown.FindItemByText(e.Item.OwnerTableView.PageSize.ToString()).Selected = True

End If

end sub

The boxes for my MasterTableView and the DetailsTables come up with the correct entries. When I change the entry in one of my SubCodes DetailTables the system does not recall my RadGrid1_NeedDataSource and refresh the screen. It does if I change the entry in the MasterTableView. I believe it has something to do with assigning the ownerTableViewId to e.Item.ClientID for the SubCodes. What should I be doing. Below is the Page_Init function on how I create the radGrid.

No Postback immediately after client-side validation

Hi,

I'm using a combination of RadTabStrip and RadPageView and have several RadTextBox, RadComboBoxes and RadButtons in those RadPageViews, and some of those use the RequiredFieldValidatior, RegularExpressionValidator etc. for client-side validation.

The AutoPostBack and CausesValidation properties of the TabStrip is set to 'True' so that whenever the user clicks on a Tab, the validation is fired for the current tab. Also, the TabStrip and PageView are ajaxified using the RadAjaxManagerProxy.

The scenario is :
- User clicks on the 2nd tab, or any control that causes validation after filling up the details in the first tab.
- A few controls fail validation and the error messages are shown in the ValidationSummary.
- Now, all controls on this tab, that cause postback, do not cause postback on the first attempt. e.g. if the user clicks a RadButton that causes postback, the button now needs to be clicked twice to work. Similarly, if there is a RadCombobox that causes postback, the user needs to make 2 selections in the combobox to have the postback occur.

Why does this happen ? I'm clueless ! Please help me resolve it.

New Batch Editing modified cell count

I'm struggling to find a way to retrieve if any cell has really been modified through batch editing.
I'd like to show the SAVE CHANGES and CANCEL CHANGES buttons, only if some editing really took place.
I already found to show/hide a button inside a toolbar in the Command Item template but I'm struggling to know if is there any cell that have been modified (when the little red triangle in the corner appear).
I went down to the ._changes object but with no much luck since the object is empty at start but if you modify a cell and then revert it back to initial value, the ._changes object is no more empty even if no red triangles appear and no batch editing happened after all.

Here is what I come up with so far (but it doesn't work for the reason above):

function ShowBatchUpdateButton() {

var toolBar = $find("RadToolBar1");

var button = toolBar.findItemByText("Nuovo");

var grid = $find("<% = RadGrid1.ClientID %>");

if (!jQuery.isEmptyObject(grid.get_batchEditingManager()._changes)) {

button.set_cssClass("ShowGridCommandBarButton")

} else {

button.set_cssClass("")

}

How can I spot if there are any red marks on the grid? (because this is what I'm looking for to show/hide the UPDATE and CANCEL buttons in real time)
