On Update Command see if anything changed

I have a RadGrid which has 7 columns. I am using InLine editing for my Edit Mode. What I am looking for is a concise way to check to see if anything changed on the Update Command, without having to look at each cell / column for the row that is being edited. Is there a way I can check to see if anything on this row was changed and then if so i can loop through each column and check, but if not I will not do anything? I am looking for something on the server side not client side.

thanks

Firefox window.getComputedStyle error in Iframe

Let me first start off by saying that this problem is in Firefox only.

I'm trying to use the ImageEditor in a simulated "popup" with an iframe inside of it. See the attached example-usage.jpg for a sample of how I intend to use it.

The typeError specifically occurs when LiteView.js from the ImageEditor resources. See the attached console-log.jpg for the screen capture of the console log indicating the error.

I know that Firefox has issues with getComputedStyle if the iframe is hidden with display:none - mine is not. I know that there are several other quirks with getComputedStyle in Firefox specifically.

If I move the editor out of the "popup" and into a regular page it functions fine.

Is there anyway to force a width with CSS or javascript so that getComputedStyle will return a value. Can I override a javascript function on this page to prevent the typeError? Do you guys know what LiteView.js is trying to do?

Any solutions appreciated.

Update control in master page after database changes.

Hi,

Using this ajaxify exampleI need execute code in codebehind, and then update the master page control

https://docs.telerik.com/devtools/aspnet-ajax/controls/ajaxmanager/how-to/ajaxify-and-update-controls-in-master-and-content-page

Something like this:

Content Page

protected void Page_Load(object sender, EventArgs e)

{

RadAjaxManager AjaxManager = RadAjaxManager.GetCurrent(Page);

RadMenu RadMenu1 = (RadMenu)this.Master.FindControl("RadMenu1");

AjaxManager.AjaxSettings.AddAjaxSetting(btnSaveChanges, RadMenu1);

}

protected void btnIncrease_Click(object sender, EventArgs e)

{

     ...

     context.SaveChanges();



     // And then, Update Radmenu in MasterPage

}

In my scenario, RadMenu have a CSS indicador of numbers of items in database updated in Page_Load(). But, when I click in btnSaveChanges in Content Page, always RadMenu update before database is changed.

Any way to reverse this?

Thank you!

Mulitple AjaxControlIDs in AjaxSetting

Hi everyone,

when I add AjaxSettings to my pages i often have to repeat the same Ajaxsetting for each ajax enabeld control

    
            <telerik:AjaxSetting AjaxControlID="Button1" >  
        
              <UpdatedControls > 
        
                 <telerik:AjaxUpdatedControl ControlID="container" /> 
        
              </UpdatedControls> 
        
              </telerik:AjaxSetting>         
        
            <telerik:AjaxSetting AjaxControlID="Button2" > 
        
              <UpdatedControls > 
        
                <telerik:AjaxUpdatedControl ControlID="container"/> 
        
              </UpdatedControls> 
        
            </telerik:AjaxSetting>

this settings list tends to get very long. Would it be possible to combine the settings for example like this

    
             <telerik:AjaxSetting AjaxControlID="Button1,Button2" > 
        
                        <UpdatedControls > 
        
                            <telerik:AjaxUpdatedControl ControlID="container" /> 
        
                        </UpdatedControls> 
        
            </telerik:AjaxSetting>

Please share your thoughts on this.

Grid height problems again

I'm struggling to set 100% height on a grid. I've seen many threads open on this subject and a few code samples too but they are all too simple.

The main issue is that there is a <div> element generated (usually has an id of the form ...._GridData) that has an inline style like this:

    
            OVERFLOW: auto; WIDTH: 100%; HEIGHT: 10px

and thus the content will always be in a 10 pixel high box. Even if I set the Height attribute of the grid to something fixed that div stays 10 pixel high and only the lower pager area grows in height so that the grid will respect the given height.

The question is why does that div has that hardcoded height? What would be the purpose of having such a default anyway?

Find and select an item in Listview with paging

Hello,

I hope someone can help me out with the following problem.

I have a usercontrol with a ListView which I have bound to a list of productimages. There are 12 items in the listview and I have set the pagesize to 4. This means I have 4 pageindexes.
In another usercontrol I fire an event with should look up the productimage in the above listview. What I want is to lookup the item in the listview which matches the parameter I send from the second usercontrol. As long as the parameter matches an productimage which is present in the selected pageindex it works all fine. But how can I look into all the items that are bound to the Listview and then select that item and set the correct pageindex

For a demo you can look at http://roosjen.uitverkoopinnederland.nl/index.aspx?contentid=233
On the left hand you can click on [Bekijk productinfo] and on the right topside the corresponding productimage should be set.

Thanks in advance.

Kind regards Patrick
