When in grid lifecycle can you set CurrentPageIndex?

I am wanting to use a cookie to remember the grid page number so when users go to a detail page and then come back it will remember the page number the grid was on. I have the code below to read the cookie, but I am not sure when in the grid life cycle I should set the CurrentPageIndex. Thanks in advance.

if (CookieUtilities.HasCookieItemValue("crl", "PGN"))

{

int result;

if (int.TryParse(CookieUtilities.GetCookieItemValue("crl", "PGN"), out result))

{

if (rgSalesCallList_SalesCallReportList.PageCount > result)

{

rgSalesCallList_SalesCallReportList.CurrentPageIndex = result;

}

else

{

rgSalesCallList_SalesCallReportList.CurrentPageIndex = rgSalesCallList_SalesCallReportList.PageCount - 1;

}

Adding a Stylesheet from inside a UserControl

I'm loading a UserControl from my page markup.

The page has a RadStylesheetManager on it.

I want to ensure my page has a particular stylesheet loaded and I don't want to rely on the developer using the control loading the stylesheet on the page explicitlt. So I thought that something like this might work ...

RadStyleSheetManager mgr = Page.Items[typeof(RadStyleSheetManager)] as RadStyleSheetManager;

if (mgr != null)

{

StyleSheetReference ss = new StyleSheetReference();

ss.Path = Page.ResolveUrl("~/StyleSheets/Popup/InlinePopups.css");

ss.Name = "InlinePopups";

mgr.StyleSheets.Add(ss);

}

Now mgr is being correctly populated. But when the page runs, I get this ...

So, what am I doing wrong?

Scheduler stops handling date selections

I am using your scheduler control to perform scheduling of activities. The control is displayed exclusively in the month view.

When a date is clicked, the app will open a RadWindow to create an appointment for the selected date. After processing the appointment, the popup window is closed. After that point the scheduler will no longer handle SwitchToSelectedDay events. Clicking the calendar will continue to generate postbacks with the event data, but the code to handle the event is no longer fired.

Why?

CheckBox problem in EditMode="EditForms"

Hi all!
I created a template for editmode. And set

EditMode="EditForms"

When click on "Edit", it shows correctly what I designed.
But the Checkbox doesn't automatically checked.
I mean when I edit a specific row, the checkbox of that row should be set to TRUE. Please attack the pics!
(This problem doesn't happen when EditMode="InPlace")

Thanks!

Andy.

RadEditor keypress event

I need to create a Javascript that does the following:

Detect when the first key is pressed in the RadEditor
Locate the cursor
Programatically insert a piece of text where the cursor is
Allow the normal process to continue, ie the key pressed by the user is to be added immediately after where I added the text.

I managed to do this for non-telerik normal text areas. But it is giving me big problems with telerik RadEditor.Net2.dll version 7.2.0.0

On clientload of rad editor I am adding a KeyPress event handler. However, in keypress method I am unable to get the cursor position. I am using this script:

function getCaret(editor) {

if (editor.selectionStart) {

return editor.selectionStart;

}

else if (!document.selection) {

return 0;

}

var c = "\001";

var sel = document.selection.createRange();

var dul = sel.duplicate();

var len = 0;

dul.moveToElementText(editor); <-- GIVES JAVASCRIPT EXCEPTION OVER HERE

sel.text = c;

len = dul.text.indexOf(c);

sel.moveStart('character', -1);

sel.text = "";

return len;

}

What do you recommend? Am I approaching this incorrectly for RadEditor? I really need to get this working!

Paging not working

hello everyone,

I am working with the radgrid and I have issue where paging is not working. Let me be more specific: set page size isn't working and going to individual pages using the "go" button isn't working.

I have tried everything i can think of.

    
            <telerik:RadAjaxPanel runat="server" ID="rapResource" LoadingPanelID="ralpResource"> 
        
                <telerik:RadGrid ID="rgResourceList" runat="server" AllowPaging="true" PageSize="15" > 
        
                    <MasterTableView AutoGenerateColumns="false" PageSize="15" AllowPaging="true"> 
        
                        <Columns>

Any help would be greatly appreciated....
