Hi,

In TimeSlotCreated we do lot of processing on server and accordingly set the slot availibility.

In NavigationComplete we get the new visible dates from VisibleRangeStart and VisibleRangeEnd. If the VisibleRangeStart and VisibleRangeEnd changes i.e. if they are outside our cache data, we need to refresh our data and then set the slot availibility in TimeSlotCreated.

But we noticed that when user changes the date or moves back/forward using the navigation link, TimeSlotCreated is called before (with old dates) and after NavigationComplete event (with new dates).

Why TimeSlotCreated is called before NavigationComplete is called since the new dates are not set anyway?

Is there a way to prevent this? i.e. TimeSlotCreated gets called only after NavigationComplete? Or is there a way to get the new visible dates before TimeSlotCreated is called?

Thanks,
Abhijeet

Email link closes grid and forwards to aspx page

I had this problem before and never got and answer to it when i submitted a help ticket and now I am back to it becuase I have another case where I need to impliment it in a radgrid and cannot go back to a asp grid. What is happening is that I need a link button or hyperlink button on a radgrid that when they click on it it opens in a new window a page to email personnel. problem is when I do this it forwards the page to the email name or site in this case, need it to stay at grid and open a the email page and pass a variable to it.

   <telerik:GridTemplateColumn HeaderText="MAC #">
                                            <ItemTemplate>
                                                <asp:LinkButton ID="lnkEmail" runat="server" CommandName="Email" CommandArgument='<% #Bind("intUserId") %>' text='<% #Bind("strMacNum") %>'
                                                ToolTip="Email the IMO"></asp:LinkButton>
                                            </ItemTemplate>
                                        </telerik:GridTemplateColumn>

Right now its redirecting but i cannot have this, just needs to open the email page in another window while staying on grid page.

If (e.CommandName = "Email") Then
            Dim RecordId As Integer = e.CommandArgument

Response.Redirect("Email.aspx?Email=" & RecordId)

End If

also tried this but no go, forwards the grid to email page.
ClientScript.RegisterStartupScript(Me.GetType(), "OpenWin", "<script>openNewWin('" & url & "')</script>")

Grid Question. Is it possible to save a row in a grid on click of a cell?

My Scenario
I have a grid which allows inline editing. When the user clicks a hyperlink in any row I open a radwindow. The hyperlink is a template cell and I open the RadWindow via javascript which all works fine except that I need to be able to save the row before opening the radwindow if it is in edit mode because I'm passing in the unique id of the row and if it is a new row I need to perform the insert command first so that the Id is generated on the server. The data is in SQL and the Id is an Identity column. I'm also using automatic updates on the grid.

My Question
Is it possible to save the row and invoke the insert command when the user clicks the hyperlink/template cell? If so can you provide sample code on how this could be done from javascript or server side code. Both would be idea. Thank you!

Here is the template column used to open the RadWindow
<telerik:GridTemplateColumn HeaderText="Selection Options" UniqueName="SelectionOptions" AllowFiltering="false">

<ItemTemplate><a href="#"

onclick='openAnswerOptionsWindow('<%# DataBinder.Eval(Container.DataItem, "LCFormMetadataId") %>'); return false;'>

SelectionOptions</a></ItemTemplate>

</telerik:GridTemplateColumn>

Here is the javascript I use to open the RadWindow

function openLCFormManagementWindow() {
var oWnd = radopen("LCFormMaintenance.aspx");
oWnd.Center();

}

Deleted files still upload

Hi There,

in the demo below:
http://demos.telerik.com/aspnet-ajax/upload/examples/async/webmail/defaultcs.aspx

If you select two files to be uploaded and then delete one by pressing the delete icon and then press send both files appear on the next page. In my testing I have not been able to inform the Upload control to not process the deleted file. So on postback the FileUploaded event gets fired and the upload control still has 2 files attached.

I understand that the files get uploaded to the temporary location but it would be good to have a property in the FileUploadedEventArgs for the file if it was deleted client side.

Any ideas on a work around would be greatly appreciated.

Regards
Jason

scheduler refresh after rowHeight modified by JS

Hi,

I wrote this code :

function SplitterLoaded(splitter, arg) {

var scheduler = $find("<%= RadScheduler1.ClientID %>");

var hauteur = window.innerHeight - 71;

var

slots = (((scheduler.get_dayViewSettings().dayEndTime / 1000) / 60) - ((scheduler.get_dayViewSettings().dayStartTime / 1000) / 60)) / 15

scheduler.set_rowHeight("" + Math.round(hauteur / slots) + "px");

var pane = splitter.getPaneById('RadPane1');

var height = pane.getContentElement().scrollHeight;

splitter.set_height(splitter.get_height() - pane.get_height() + height);

pane.set_height(height);

}

but when I call

scheduler.set_rowHeight("" + Math.round(hauteur / slots) + "px");

the timeslot doesn't resize dynamically.

how can I refresh the scheduler ?

thanks.

RadToolBar with Download file

I'm using RadToolBar to create some RadToolBarButtons for user to download file from the file system. For example, one button for user to download Excel version user guide and the other version for user to donwload PDF version user guide. The program work fine under IE, but the program can not be run under Firefox. When the user using Firefox to access such webpage, first time he/she clicked RadToolBarButton to download PDF version user guide, after that, the entire became non-functional. No any effect after the Excel button is clicked.
My project is quite simple and contains one webform only. Here is my code

Triggering JavaScript on SelectedIndexChanged 'after' postback

I have a ComboBox within a RadGrid that performs a database lookup within its selectedindexchanged event in the code behind and populates several other radnumerictextboxes within that same grid row. I have a JavaScript function on the page that is called when the value of some of these radnumerics (such as quantity) are changed in order to recalculate some totals.

ie: quantity * db lookup value = total.

My problem is, I need a way to call that Javascript function AFTER changing the selected index of the ComboBox (and therefore after the postback) I'm trying to avoid duplicating the javascript code in the selected index changed in the code behind. Far better if I could just call the Javascript function after the postback required for that lookup and only when that lookup dropdown is changed.

Any ideas?

SelectedIndexChanged firing involuntarily after a postback

Good afternoon,

I have the following problem in my RadGrid have a column with the command button "select" to fire the SelectedIndexChanged event.
So far so good, when you click the button, it triggers the normal SelectedIndexChanged event.
The problem occurs when I select a row, without clicking on the button by clicking on the same line, and soon after I click for example on one other button, by doing this, it seems that for the button to cause a postback on the page, it triggers the SelectedIndexChanged event of RadGrid.

Tooltip + RadComboBox

Hi I have a RadCombobox that is Enable Load On Demand - Handled code side.

I've attached an event to the OnClientItemsRequested event, which displays a tooltip if the text entered into the RadCombobox does not return any items. - I did it client side as i was having difficulties getting it to work by showing it from the code behind.

The majority of cases this is fine, but i've experienced it sometimes showing before any results have been returned from the database.

I have one client who is being quite insistant in telling me that he can type something, gets a tooltip showing 'No results for <his search>' when there are actually results for his search, they just haven't been returned from the database yet.

Can someone suggest how I can prevent this happening, and only show the Tooltip if no results are returned.

Here is the code for my 'checkFound' function incase you need it.

function checkFound(sender, args) {

var count = sender.get_items().get_count()

if (count <= 0 && sender.get_text().length > 0) {

var tt = $find('<%=tt_searchArea_empty.ClientID %>');

tt.set_text("No results found for '" + sender.get_text() + "'");

tt.show();

}

else {

hideAreaEmptyToolTip();

}

function hideAreaEmptyToolTip() {

var tt = $find('<%=tt_searchArea_empty.ClientID %>');
