Making a help guide and help text to load dynamically with Ajax straight from the database.

Hi,

I need to make a help guide using RadTreeView.

For Example : http://www.telerik.com/help/aspnet-ajax/using-radcontrols-net20-30-35-projects-vs2008.html

However, the Help text load should load dynamically with Ajax straight from the database. I dont want the entire page to refresh, only the text content area on the right should load and show the new content. Also, all the nodes should load at once.

Request help on how I should go about the above. Any help - documentation/ code / instructions is welcome.

Many Thanks,
Ritika

Customise Image Editor

I have several questions regarding the Rad Image Editor:

1) I would like to pass two values (crop x & y) from the main page code behind to the imageEditor? Thus allowing the user to select an area of the image they want to use in the calling page. In addition I would like crop to be enabled in the imageEditor (by default)

2) Can the number of controls available to the user be reduced (e.g. remove opacity, flip, rotate and crop) what is the best way to customise the imageEditor.aspx file?

3) Is it possible to have a maximise/restore default icon (in the top right of the window, next to ‘x’ Close) to increase the page size is the user has a large image?

4) If the user uploads an image that is too big to fit in the imageEditor, is it possible to automatically resize the image to fit the available size?

Please note:

I am opening the image manager directly using the dialog opener.

Add/Edit RadGrid records in RadWindow with Javascript disabled

Due to accessability requirements, I was wondering if it is possible to add/edit grid records in a RadWindow with Javascript disabled? If so, could you please explain how to do so.

I can open a RadWindow outside of a RadGrid with javascript disabled, which opens in a normal popup window. However, I tried to use the same mechanism with an "Add New" button in the CommandItemTemplate of a RadGrid, but my asp:hyperlink control does not get declared in the code behind. I havn't even attempted to get the "Edit" and "Remove" operations working with Javascript disabled yet.

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<telerik:RadWindowManager ID="ohsRadWindowManager" runat="server" KeepInScreenBounds="true" ReloadOnShow="true" ShowContentDuringLoad="false" VisibleStatusbar="false" >

<telerik:RadWindow ID="radObserverAdd" NavigateUrl="Popup/Observer.aspx" OpenerElementID="<%# lnkObserverAdd.ClientID %>" OnClientClose="ReloadParent" runat="server" Title="Add observer">

</telerik:RadWindow>

</windows>

</telerik:RadWindowManager>

...

<telerik:RadGrid runat="server" GridLines="None" ID="rgObservedBy" AutoGenerateColumns="False" EnableViewState="false" Visible="true">

Catch events grid columns.

We bought the package of controls and enjoy your very use it!

In use Grid - are there a possibility to catch events of grid controls?

We have two GridDropDownColumn one of the city and other of the street - we want that on choice of the GridDropDown city the GridDropDown street, will be refresh by the selected city.

The question is how catch the event on server side GridDropDown events?

We tried to register to the event on Grid_itemDataBound event but apparently it's too late Because It did not register.

protected

void Grid_mdr_Midrasha_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

RadComboBox list = (e.Item as GridEditableItem)["iCityId"].Controls[0] as RadComboBox;

list.MarkFirstMatch =

true;

list.SelectedIndexChanged +=

new RadComboBoxSelectedIndexChangedEventHandler(list_SelectedIndexChanged);

}

Is there difference performance issue between IE and firefox?

hey~

I have a treeview with 200 records(per record with one picture, ex: folder.gif or trashcan,gif ), when we use Firefox, the page is running well(2-3 sec), but when we use IE6, the page is running vary slow(20 sec). It seems there are too many pictures(more than 400 pictures) to be loaded in IE, but this situation doesn't happen in Firefox.

so, there are two question:

1. Do we miss something to know when we use this treeview?

2. what's the cause there are so many picture need to de load? could we reduce the number of picture?

thanks.

Month/Year RadDatePicker for Chinese

Having a issue with the Month/Year RadDatePicker script provided at http://www.telerik.com/community/code-library/aspnet-ajax/calendar/month-year-picker.aspx. It is working as expected for other cultures except Chinese.

To reproduce this issue

1) download the sample and add a Culture="zh-CN" attribute to the RadDatePicker tag

2) Run the project and pick a 2 character month (i.e. Jan-Oct).

The month in the input box changes to Jan always unless a 3 character month is selected (i.e. Nov or Dec)

The issue is in the RadDatInputScript.js at Token.FindIndex where it assumes all the abbreviated month names are at least 3 characters long.

Token.FindIndex=function(_7d,_7e){

if(_7e.length<3){

return -1;

}

for(var i=0;i<_7d.length;i++){

if(_7d[i].toLowerCase().indexOf(_7e)==0){

return i;

}

I changed the condition to check for at least 2 characters instead of 3 but the format of the month in the month/year select popup drops the last character of the 3 character month to the next line. It is not a proper fix but for the moment it seems fine but I would like to have a proper fix.

Thanks

Problem with custom skin

I have created a custom skin for the panel bar. I have altered the RootItemBg.gif.
I have added it to App_Themes and have added the theme to the Page. I have Enabled EmbeddedSkins set to false and the skin set to my skin name.

The skin works except fo on thing. It does not show the RootItemBg.gif. Is there a step I am missing?
