Hi,

      I am using a RadGrid control (Rad Controls for ASP.NET AJAX Q3 2009 NET20) to display data. I am not sure why my  control is not displaying data at all when I navigate from my first page. Below is the sample I am working with. Please help me understand what I am missing and how to rectify.

Thanks in advance.

Krishna Chaduvula.

Hopefully this is an easy one.

I have two related grids on a form and I am using a Master/Detail setup as described in one of the demos and this works great.

Here is my ASPX Code


And here is my VB code


Rather than have the user select a row from the master grid, what I would like to accomplish is to not require the user to select anything in the master grid. I would prefer that when the master grid has data in it, the details grid automatically displays the related data.

Example Data

User Job Role - OfficeAssistant    has the related TaskRolls - BasicUsage, StudentView, and ViewAllTables
User Job Role - AttendanceClerk  has the related TaskRolls - AbsenceLetters, CurrentClasses, Contacts, Disipline

When a user selects a UserName from a Dropdown list, the master grid would populate with the user's Job Roles and the related grid would automatically populate with the Task Roles for both Job Roles.

   Job Roles                          Task Rolls
------------------                ------------------
OfficeAssistant                  BasicUsage,
AttendanceClerk                StudentView
                                       ViewAllTables
                                       AbsenceLetters
                                       CurrentClasses
                                       Contacts
                                       Disipline

I hope this makes sence.

In our application we are using radgrid where we are going to select  three things like a,b,c from combo box where 'b' depends on 'a' and 'c' depends on 'b' (selected change event of combobox) after clicking on add it should add to grid but not to database. And i should be able to delete, edit rows.When i Save my page then all the rows should be read and stored in the table.

Hi

How can I restrict the user to select only a docx file for upload and to catch it if it’s not?

Thanks

Hello,

Often I have a form that has these values:

RadTextBox
RadNumericTextBox
RadDatePicker
RadComboBox
RadMaskedTextBox

I often use a CustomValidator control to validate the form to ensure at least one value has been provided in the form.  Rather than write code to check each an every control to see if it has a value, is there one JQuery condition I can write to check to see if any of the controls have a value?  I tried using a CSS class to identify each control, and then target that control by doing something like:

$("#wrapper").find(".TelerikControl[value != null && value != '']").length > 0

To determine if there is any value present, but this doesn't quite work.  Can anyone share if they did this and how?

Thanks.

I have hooked into OnClientNodeDragStart to remove the event hookup of a  jQuery Tools Tooltip, but it appears there is no client side event that I can hook in to to add these events back if I don't complete the Drag/Drop or decide that I want to cancel and drop the item onto its self.

This removes the jQuery functionality, but if I cancel the drag, i'm not sure there is an event that will wire it back up...

hi i tried retriving the gridboundcolumn values as below
and i am getting &nbsp as the value is there any other alternative ??

When using the new feature mentioned: here (Slot Selection), I've encountered the following bug. 
I've defined a context menu inside my schedule control as follows:


Then server side I dynamically add child menu items to this root item: 


I attach to the TimeSlotContextMenuItemClickedEventHandler event server side, and when I get the TimeSlot object from the TimeSlotContextMenuItemClickedEventArgs it doesn't contain the full duration of the selected timeslot, instead its just the block of time like 9-9:30.

I am doing something wrong here?  How do I get the full duration of the selected time slice, on the server side?

I created a support ticket for this as well, but wanted to see if anyone else has experienced this.

Currently I have a page which contains a RadGrid (with subgrid), RadToolTipManager, and RadAjaxManager. I have a GridHyperLinkColumn which I selectively disable the URL of in the code behind. When the URL is disabled I add a tool tip by adding the columns ID to the RadToolTipManager TargetControls collection. 

The RadAjaxManager has the Grid set to update the itself as well as the RadToolTipManager. 

I'm able to use the various paging and sorting controls and still have the tooltip appear where it should. As soon as I expand a sub-grid is where I'm running into a problem. The tooltip that appeared just before the sub-grid request will no longer appear for the same cell. 

One thing I did notice is that before the sub-grid request the TD element had an ID while after the request the ID was gone. I'm guessing that since the ID of the element is gone the RadToolTipManager is not able to tooltipify the cells since its not technically part of its TargetControls collection.

Any idea as to why the TD element loses it ID during the AJAX postback?

I'm working on a project to attach to this. I'll hopefully be able to demonstrate this issue.

hi, 

I have Grid with 1 DetailTable, and there are static columns with GridButtonColumns, clicking which should open new page with  parameter.

The call to popup page is in code behind:

In debug mode, I put breakpoint in - ClientScript.RegisterStartupScript(cstype,"History", popupScript);

It reaches there, but the page is not poped up. What I am doing wrong ?

Here is aspx code:
