Hi There

I have a situation in which I have grid with numeric column on the web page and I have a numeric column on the web page as well.

I would like to compare the sum of all the grid numeric column values with the value of numeric column on the web page.

For example I have a value of 10,000 on the numeric column on the page and I have four records in the grid with the value 1000, 2000, 4000,2500 total=9500 which is less than 10,000 the value of my numeric column on the web page

And I am going to edit the fourth record (using Edit form mode) with the value say 5000 from 2500. Now the total value is greater than 10000 so I would like to warn my user using client side Java script and put the focus back again inside the grid numeric column so that he can change the value so that the value should not be greater than 10,000

So I would like to know the way how to calculate the total of particular numeric column of all rows including the edited row using Java script on focus out or on update client side event

In short I need to find a way to loop through all the rows including the one I am editing on the client side

Your help will be much appreciated

Many thanks

I have two data controls that users can switch between, one a datagrid and one a RadListView that is tied to the datapager below:

   <telerik:RadDataPager ID="RadDataPager1" runat="server" PagedControlID="listResults" PageSize="20">
                                      <Fields>
                                <telerik:RadDataPagerButtonField FieldType="FirstPrev" />
                                <telerik:RadDataPagerButtonField FieldType="Numeric"  />
                                <telerik:RadDataPagerButtonField FieldType="NextLast" />
                               <telerik:RadDataPagerNumericPageSizeField LabelText="Page Size:" SubmitButtonText="Change"  TextBoxWidth="25" Visible="true" />
                                <telerik:RadDataPagerGoToPageField CurrentPageText="Page: " TotalPageText="of" SubmitButtonText="Go" TextBoxWidth="30" />
                                
                            </Fields>
                                     </telerik:RadDataPager>

The datagrid works just fine when changing the page size and hitting the enter key. The RadListView version I have with datapager does not.

I ended up just creating a hidden submit button and setting the default button for the whole page to that but really this is just a work around and to me the RadDataPagerNumericPageSizeField in RadDatapager should act just like the pager control built in to RadDatagrid.

With the hidden submit button the Datagrid still acts normally when changing the page size and hitting enter (which is great and the way I want it to act).

I want to get all data of a Radgrid into a datatable but my Radgrid includes GridTemplateColumn and when I use the normal code to get the column and rows in a datatable it gets back some of bound columns empty. Would you please help me to know what should I do?

Hi,

Can I set images URL from a data source instead of image data field? In my situation, we save only image url in database.

Thanx

Hi,

Is there a way to enable resizing but only when in 'Preview' edit mode? At the moment, it seems that resizing only works when editor is in 'All' edit mode. When set to a specific edit mode, the bottom of the editor (which allows resizing) disappears.

Thanks.

Has anyone managed to create a FileBrowserContentProvider to handle physical paths outside the web app? I have a scenario where I need files to be managed outside of the application, and it appears that everything wants virtual paths!

Looking at the demo I also thought of using a httphandler for the files, however that isn’t working. I got as far as getting the directory tree to show in the left tree view however no files are being shown.

I am by no means an ASP.net expert and am still learning the ropes, so if anyone can point me in the right direction I'd be most grateful.

I Keep getting errors like below thrown up:

---------------------------
Message from webpage
---------------------------
Callback Loading error:
D:\Test\

I have a page that I have has a fileExplorer on it.  All seems to work except the upload.  When I upload a file I always get this error and it opens a dynamic block of code.

JavaScript runtime error: Unable to get property 'get_selectedItem' of undefined or null reference

The file still uploads but not sure why this error is happening. 
I am runner version 2013.2.717.35 on a 2.0 framework asp.net app.

Hi

I have implemented the custom file browser as specified in the online resources. I am using shared paths like "\\172.0.0.0\images".

Everything else seem to work except for thumnails view.

I also tried cssclass - rfethumbnails but it doesn't help.

I have implemented all 4 methods that determine thumbnails for the images.

        {
            string fileName = Path.GetFileName(RemoveProtocolNameAndServerName(url));
            return fileName;

        {

            // First add the '~/' signs in order to use the VirtualPathUtility.GetDirectory() method ;
            string PathWithTilde = "~/" + path;
            string virtualPath = VirtualPathUtility.GetDirectory(PathWithTilde);
            virtualPath = virtualPath.Remove(0, 2);// remove the '~' signs
            return virtualPath;            
        }
