Page Navigation

Hello,

I need some help with this:
I have 3 pages:

the main page,
a rad window
and a 3rd page.

from the main page you can click a create new button and the radwindow opens and inside the radwindow there is another button that redirect's you to the 3rd page. on the 3rd page there is a "go back" button that sends you back to the radwindow. Now you can also go from the main page to the 3rd page if you need to edit an existing item.
my problem is that when i try to go from the main page to the 3rd page to edit and then try to go back usin the "Go back" button my page is redirecting me to the radwindow but I want the button to send me to the main page.

is there a way to make a page redirect depending on the page that it came from?

thanks

[Solved] How do I get the SelectedIndexChanged method to fire

Hi. I want to put my own code to execute on the SelectedIndexChanged event for the RadGrid. At the moment the event only occurs when I click the edit link. I assume that to get the event to occur is a simple property that I haven't set. I want to just be able to single click on a row in the grid and for my code behind to execute. I had assumed that clicking a row would "select" it and thus trigger the event but that isn't happening. Any help appreciated. Thanks

Horizontal scroll position getting reset when Ajax call is made from OnClientContextMenuShowing() function

Hi,

We are facing an Issue with the position of horizontal scroll of the rad tree view when we right click on any node of the tree to open its context menu.

Suppose this scenario:- A user moves the horizontal scroll of the tree view towards right, then he right clicks on any tree node to open the context menu. When the context menu is visible, the position of the horizontal scroll is moved to the extreme left and do not remain at the position where the user has last left it.

In the javascript function OnClientContexMenuShowing() we are making an Ajax call using the AjaxManager. Code is present below for your reference. It seems to me that this Ajax request is some how resetting the position of horizontal scroll bar to initial position( extreme left). Do we have any work around for thi Issue.. ?


<

 

rad:RadTreeView ID="RadTreeView1" runat="server" Height="96%" OnClientContextMenuShowing="OnClientContextmenuShowing"


 
 

 

OnClientNodeClicked="OnTreeNodeClick" OnClientDoubleClick="OnTreeNodeDoubleClick"
 

 
 

 

OnClientContextMenuItemClicked="OnTreeContextMenuClick" OnClientNodeExpanding="toggleHandler"
 

 
 

 

OnClientNodeCollapsing="toggleHandler">
 

 
 

 

</rad:RadTreeView>

 

function OnClientContextmenuShowing(sender, e) {  
  
//Get the ajax manager object 
  
clientAjaxRequest("UpdateMenu");  
   
return false; 
}

function clientAjaxRequest(arg) {

var ajaxManagerObject = $find("<%= RadAjaxManager1.ClientID %>");

ajaxManagerObject.ajaxRequest(arg);

}

Using ResizeMode="Fit" with ImageUrl

Accordining to http://www.telerik.com/help/aspnet-ajax/radbinaryimage.html
"ReziseMode" specifies whether the image should be sized automatically if width and height of the image are set in pixels. Possible values are:

Crop (the image will be trimmed)
Fit (the image will be sized to fit the given dimensions)
None (default)

Using the code

<

telerik:RadBinaryImage ID="RadBinaryImage1" runat="server" ImageUrl="Photo/Grid-Scrolling-Issue.jpg" ResizeMode="Fit" Height="100px" Width="100px"/>

Renders

<img id="RadBinaryImage1" src="Photo/Grid-Scrolling-Issue.jpg" style="height:100px;width:100px;" />

and the image is 100x100 px on the page

However, the file size downloaded to the browser is still its original file sze 1.25MB; which is not what we were hoping for. We would like to use the control to produce a thumbnail image that has a small file size and dimensions.Can this be done with the Binary image control?

Our images are files on the server and not in a DB; that is why we went the ImageURL approach.

Can the actual image size be reduced along with it's dimensions with this control, if so how?

Thanks in advance,

K.E.

Changing table layout in a self referencing Hierarchy

Hi

I have an expanding grid with a self referencing hierarchy that can go to a variable depth so I can't use nested detail tables, so after some experimenting I started using the self referencing hierarchy and came up with the following code.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False"

OnDetailTableDataBind="RadGrid1_DetailTableDataBind" GridLines="None"

onitemdatabound="RadGrid1_ItemDataBound" >

if ((bool)item.GetDataKeyValue("IsCriteria") == true)

{

item.Cells[0].Controls[0].Visible = false;

}

At first this approach seemed to work
Screenshot
but if I then expanded another row it would cut out my addidtional columns in my modified detail table.
Screenshot 2

Is it possible to modify a detail table view so that the changes persist on another row expanding?
Is there an easier/better way to do what I am attempting to do i.e. a self referencing grid with a different detail view at the lowest level?

Any help/advice will be gratefully received.

Radwindow Used as a popup in and outside an update panel

Hello
Maybe someone can help me with this little issue. Not really a bug deal but is somewhat annoying.

Here we go. I have deployed several RadWindows throughout my project as popup modal = true.
The window works well but here the catch. Whenever a button or control that fire the window is located within a update panel
Either ASP.net or RadAjax It seem that the loading panel that is incorporated with the radwindow will not display.
What happens is that a blank widow appears fully opened as per setting and remain blank until the page loads.
Now if the control is outside as update panel then the loading image load first and finally you get the PageLoad.
Is this related to full postback instead of a partial postback and is there any way around this???

Thanks in advance..
