Hi guys,

I'm trying to resize an EditableImage on the server side.


Using this code the image is simply cropped to the given resolution. Is this behaviour intended?
I was hoping for the whole image to become bigger or smaller depending on it's original size. 

Dear All
I hope to find the solution of my first problem post it at this nice forum .
I am developing ASP.Net 3.5 application
using IDE Visual Studio 2008 SP1
Fire Fox 6 web browser

I developed a web user control to work properly I need to disable and enable controls on certain condition on the client side , my user control has an updated panel .And so , I shall use the method
ScriptManager.RegisterStartupScript
Now this method works fine in context of ASP.NET controls , but when try to use it with telerik controls I found two problems

Problem : when try to disable the RadComboBox at page load I git script error that variable to handle RadComboBox is null let us see the below code , Also I got the same problem when put same code in different location were suppose the asp.net loaded successfully .for example, at button click event handler



Second : sometimes I got the below script error in the Error Console in the Fire Fox , when trying to execute code like the above code mentioned ealier

Error: uncaught exception: [Exception... "Cannot modify properties of a WrappedNative"  nsresult: "0x80570034 (NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN)"  location: "JS frame :: chrome://global/content/bindings/autocomplete.xml :: onxblpopuphiding :: line 854"  data: no]

Hi All,

I am trying to fetch the images from database, if no images are available from the data base it is showing "DBNull' Error.

If I write the following code snippet with in the binding value '<%#Eval(Picture):null?Null:Eval("Picture")%> then all the images which even have the content are not getting displayed as required. Please do help me out of this problem.

Thanks,

Hi

I have a grid with has paging enabled.

There is a Page-Size dropdown at the bottom of grid, having 5,10,20,50 as options. right now there are only 6 records, 
if user selects page size to 20 or 50,  the paging controls disappear.    What if user wishes to reset or set a new pagesize ?

We want that the pagesize control should remain on screen.  any workaround ?

Hi,
   I have been stuck on this problem for a couple of days and even with trying everything havnt been able to resolve this. I am using a Masterpage and content pages with RadGrid. I have read its better to put a RadAjaxManager on the main page and use RadAjaxmanagerproxy on each page. I have some common functions like the Show/Hide filters functionality as shown in the demos. Instead of having these and other Grid client side events I want to put  these common client side event in the Masterpage or preferably in an external js file but when i take them out and put them in the Masterpage it just does not let me access the Grid client side events like .get_MasterTableView() . Can someone from Telerik please show with an example how to access the grid and the grids clientside events in the Masterpage? Also can I call the functions  (showFilterItem() /hideFilterItem()) like showFilterItem(gridID)  and pass the GridClient ID to the masterpage somehow? I have these filter options on every page and dont want to repeat these and other client side events on every page or hard code the GridID (GridProducts, GridOrders etc) in the function like i am doing below, can someone show me by code example please how to pass in the Grid ID on every page to the master page to access the grid from there?

Note*: I did var grid = $('[id$=GridProducts]')[0];   in the Masterpage javscript since Masterpages changes the ID of the grid and it becomes something like ct100_Masterpagecontent_productGrid.

Please give an example in code on how to do this since im sure having common client side functionality is a common request and would hopefully others as well. Thanks in advance!

I have a scrollable grid and I am having trouble with the alignment of grid on IE7 and IE8.

I have attached a screenshot of what the page looks like in IE 7 and IE 8. I am using the latest RadControls for ASPNET AJAX
Below is my aspx:


If I change anything to adjust it according to one browser, it starts affecting the other browser. This is really bothering me. Please help.
Let me know if you need more info.

At which event the data of a CalculatedGridColumn is bound to the Grid?

ItemDataBound event only has data for the BoundColumns.

Update:
sorry I meant GridHyperLinkColumn is not bound on ItemDataBound; GridCalculatedColumn is fine.

when i click on "RadControls for ASP.NET AJAX Q2 2011 Documentation" shortcut or "RadControls for ASP.NET AJAX Q1 2011 Documentation"

both of them they go to    http://msdn.microsoft.com/EN-US/library/D51A087E-5B68-446B-81F2-CA0F1AEB3C79 


which it has 

Page Not Found

We're sorry, but the page you requested could not be found. Please check your typing and try again, or use the search option on this page.

I have the below GridCalculatedColumn object and it's being added to the GridTableView but it fails at runtime:

var calculatedColumn = new GridCalculatedColumn
            {
                DataFields = "Volume",               
                Expression = "iif({0}=null,'NA',{0}*100)",
                DataFormatString = "{0:0.00}%",               
            };

What is required to be done is that if the "Volume" field is null, it should display "NA" text otherwise it should display the Volume in 0:0.00 format.

How to achieve this with GridCalculatedColumn?

I'm getting this error:
Telerik.Web.UI.ParseException: Neither of the types 'String' and 'Nullable`1' converts to the other.

The data type of {0} i think is Nullable<decimal>.

Another try:

I removed the DataFormatString and put this expression:
iif({0}.HasValue, Convert.ToString({0}.Value), "NA")

and it worked but it just shows data in a different format e.g. it displays as 100.40 rather than 100.40%.

How to apply formatting inside the expression?

I used String.Format() but it gave an error message.

 Thanks guys,
