Hi,

 

I am  facing an issue with our application, the checkbox inside the Telerik  Radgrid in our application is not unchecking when it is clicked first time (as per the business logic the  grid will be loaded as few rows checked. And this issue occurring only in this scenario).  But it is unchecking on the second time clicked.  This issue we got after migrating the  application from .Net 3.5 to 4.0.

In our 3.5 application  grid is working fine in the above said scenario. we have  tried with  4.0 Telerik and Spring DLL ‘s, still we are facing the same issue.

Hi,

I am using a rad grid which is having a CheckBox column and with multiselection. Paging is enabled for the grid. If user selects one or more row in the grid and clicks on next or prev page button in the pager. A confirmation message should be displayed to user. If user clicks on "OK" in the confirmation message, i would like to perform operation(delete) and page should be changed (user should be redirected to next page), if he clicks on cancel, selection should be cleared and page should be changed.

Can you please help me with this scenario? A code sample will be of great help.

Thanks.

Hello.

We have a problem.

If I input special character  "<br/>" or "<a>" into RadTextbox and submit data,

server exception error raised  "System.Web.HttpRequestValidationException"

please let me know how can I solve this problem.

i have a radGrid that contains a 'Download file' button, that downloads file from server. The grid has a RadAjax Loading panel that shows a loading icon while time consuming operations are being performed.

The Loading icon works in all cases but interferes with Download functionality. when i select download, the loading icon appears indefinitely & after sometime the following error is displayed:

The data necessary to complete this operation is not yet available.

Detailed error:
Sys.WebForms.PageRequestManagerParserErrorException: 
The message received from the server could not be parsed. Common causes for this error are when the response
 is modified by calls to Response.Write(), 
+response filters, HttpModules, or server trace is enabled.

Following is my code:

When selecting all text and applying a different alignment (left, right, center, justify) an empty paragraph is added after each element. This happens in Internet Explorer 9.

We are using version 2012.3.1016.45 of the editor, but the same problem happens with the online demo of the editor.

Example:
We have the following HTML-code in the texteditor:


Then we do CTRL-A to select all the text and click the button to change the alignment (center, right or justify).

In Google Chrome we get this correct result:


In Internet Explorer 9, an empty paragraph is added after each element:

Hi, I'm using RadTimePicker (really i'm using DnnTimePicker, but it's the same)  in my dotnetnuke proyect.
RadTimePicker works fine, but i found a little problem.
I have the proyect in a server, if I set the mindate value for example to today at 11:00, then the  RadTimePicker mindate value is "4/12/2012 11:00". This "today" uses the server date.

Ok, its ok, if I open the solution in a client machine with the same date, all works fine, i can't select any hours before mindate.

But i think that mindate validation uses client machine "today" for compare with RadTimePicker mindate. Then if client machine has a different date, for example, 5/12/2012, if I select for example 10:00, mindate validation will compare mindate (4/12/2012 11:00) and selected date (5/12/2012 10:00) and like

4/12/2012 11:00 < 5/12/2012 10:00

I will can select this hour.

I'm not sure that this, because, If client machine has a previous date to server machine date (for example 3/12/2012), in my theory, if i select 12:00, "mindate validation" will compare:

4/12/2012 11:00 < 3/12/2012 12:00

but this doesn't happen, it's like only compares 11:00 < 12:00 and permits to select this.

I don't understand how works this validation, but one thing is sure:

- Client machine with the same o previous date that server machine: all works ok.
- Client machine with a bigger date: this don't work.


I hope that you can help me :)

Thanks, regards, Javi.

PD: sorry for my english

i have radcombo with emptymessage even though not selecting any value it is postbacking....

my code is

 

 

<telerik:RadComboBox ID="Commodity" AppendDataBoundItems="true" EmptyMessage="--Select--"

 

 

 

Width="80px" runat="server" CheckBoxes="true" DropDownWidth="150px" AutoPostBack="true" EnableCheckAllItemsCheckBox="true"

 

 

 

CheckedItemsTexts="DisplayAllInInput" OnSelectedIndexChanged="gvNetExposurefilter_SelectedIndexChanged">

 

 

 

</telerik:RadComboBox>

 

I'm using the EnableAutomaticLoadOnDemand with a RadComboBox, the EntityDataSource is defined in code behind and connected with the RadComboBox.

When I open the DropDown of the RadComboBox I get this error:

Object reference not set to an instance of object

There is an example of how to define a datasource in the code behind in this case? Is possible using EnableAutomaticLoadOnDemand?

Alberto

Is it possible to change the start time 12:00AM to "Open"  and end time 12:00AM to close on the picker?
