Get Data Source from RadGrid after PostBack

Hi,

I have a web user control that contains a RadGrid and a web page that hosts multiple instances of the web control. I set the data source for the grid as a property to the control before the page loads.

Since I have multiple controls, I cannot easily use ViewState or Sessions to get/save the data source for the grid after an operation that causes a postback of the web page and web user control (Since the keys of the ViewState or Session would need to be changed per each instance of the user control so that the contents from one instance of the user control do not overwrite the contents of the other).

I would like to get the data source back directly from the RadGrid and was wondering if this is possible and if so, how to do it.

Thanks,

Grid

See file icons with treeview explorer mode

Hi Telerik Team,

I'm using the radfileexplorer to show the content of my sharepoint 2010 library. However it was very slow when loading all my content, so I'm trying the treeview explorer mode. Just like this.

<telerik:RadFileExplorer ID="RadFileExplorer1" runat="server" Language="es-ES" OnClientFileOpen="OnClientFileOpen" AllowPaging="true" VisibleControls="Grid,Treeview" explorermode="FileTree">
</telerik:RadFileExplorer>

But the problem I'm getting right now is that I can't see my files icon. Everything loads great, but to every file loads the same icon (the unknown file one), the folders load good.

So I was wondering if there's anyway to recognize my file extension and get the correct one

Thanks in advance

Best Regards

Raúl Ortega

XSL + XML in RadEditor

Hello,
I have 2 columns in Database
1. XML_Data (Contains my data to show in RAD Editor)
2. XSL_Data (Contains my Styling to implement on the XML data.)

I am combining both of them in my code to generate final result which is shown in RAD Editor. Now if in Design mode user (say for e.g) changes the text to bold, than in HTML mode, the changes take effect which has my generated code. What I want is to make style changes in XSL_Data only and Data changes in XML_Data only.

Please HELP!!!!!!!!!

store and apply virtual path to FileExplorer

I'm writing to ask how best to store a document path in an SQL Server - if the document path is in a different drive;

For example, if a View Path is stored as \Customers - and is in the root folder of the web application, I am able to apply the path to the RadFileExplorer with the below code - after obtaining the document path from the SQL Server database:

RadFileExplorer1.Configuration.ViewPaths = listViewPaths.ToArray();

However, if the document path is in a different drive - such as

\\FLEET01\D$\Documents\Customers\ - the RadFileExplorer is not populated;

No errors occur on the web server, which indicates to me that the format is OK;

Any insight is appreciated;

Save Ajax loaded tooltip

Hi
I've used RadTooltipManager to tooltipify element , required tooltips are loaded by a webservice that is defined in RadTooltipManager
I was thinking about is it possible to save loaded tooltip locally and prevent other requests to send to server ?
Requests can be canceled in OnClientRequestStart
How can I get fetched tooltip in OnClientResponseEnd or any other possible event ?
and How can I display saved tooltip in OnClientRequestStart after canceling the request ?

Thank You Very Much , For Your Feedbacks

keyboard left/right expand collapse operations

The radtreeview node expands and collapses both using left arrow key and right arrow key. Is there a way to restrict the user to expand only using right key and collapse using left key, other than handling javascript events?

RadGrid slow paging

Hi, I know that this topic was raised here before but I can’t really get anywhere reading previous posts. Could someone point me in the right direction?

I have created a clear page , added radgrid, object data source and radscriptmanager, paging enabled(10) . Objectdatasource is using dataset based on stored procedure retrieving 100k rows. I understand that initial load time can be slow as it’s a lot of data, but I was hoping that switching between pages will be really quick. Looking at profiler when I go form one page to another the same query is executed on sql server, I am not sure why we would query for data we already have. Could someone tell me what I am doing wrong and what should I do to make it quicker ?

I am using: version 2011.1.519.35

Thank you for help

Indexing Issue Tabs not change, page does.

I have set up my tabcontrol, but when it runs it never moves off of the first one. I think it has something to do with the
selectedindex="0", but the builder didn't put anything in for that. I tried the Javascript I found on here but that just generates
an error that Microsoft JScript runtime error: Unable to get value of the property 'get_element': object is null or undefined

<telerik:RadScriptManager ID="RadScriptManager1" Runat="server">

</telerik:RadScriptManager>

<telerik:RadTabStrip ID="RadTabStrip1" runat="server" SelectedIndex="0"

ontabclick="RadTabStrip1_TabClick" Skin="Black">

<Tabs>

<telerik:RadTab runat="server" NavigateUrl="~/Default.aspx"

Selected="True" Text="Home">

<Tabs>

<telerik:RadTab runat="server" NavigateUrl="~/Careers.aspx"

Text="Careers">

</telerik:RadTab>

<telerik:RadTab runat="server" NavigateUrl="~/ContactUs.aspx"
