GridCalculatedColumn Concatination with formatting

Hello!

I'm trying to use GridCalculatedColumn in order to show concatenated and formatted values.

I need to show StartTime and EndTime as 08:45 AM - 01:45 PM
Similarly, Rate and RatePlus as £15.50 + £14.00

Successfully doing this will help me eliminate two/four columns. However, formatting is utmost necessary. My web applications culture is set to UK in web.config. The data source being fed to the grid is coming through LINQ -> DataTable -> Grid. Commenting these two GridCalculatedColumn makes everything run just fine. However, with these two columns, I get the following error upon Databind():

Expression of type 'System.Nullable`1[System.DateTime]' 

cannot be used for parameter of type 'System.Object' 

of method 'System.String Concat(System.Object, System.Object)'

I have confirmed that no null value is present in the result of the query.

<telerik:GridCalculatedColumn



    UniqueName

="Timings"



    HeaderText

="Timings"



    DataType

="System.DateTime"
DataFields="StartTime, EndTime"



    Expression

='{0} + " " + "-" + "; " + {1}'
DataFormatString="{0:hh:mm tt}"

/>

<telerik:GridCalculatedColumn



    UniqueName

="Rates"



    HeaderText

="Rates"



    DataType

="System.Decimal"
DataFields="Rate, RatePlus"



    Expression

='{0} + " " + "+" + "; " + {1}'
DataFormatString="{0:C2}" />

Any help will be highly appreciated.

Regards.

JS error in RadGrid when resizing columns in Ajaxify Timer example

Hi, We're using Telerik ASP.NET AJAX (2011 Q2) in our product. in some pages we need to refresh the RadGrid by timer every 10 sec. As it's described in "Ajax / Ajaxify Timer" demo example in here . The example just shows a grid without any client side grid features like resizing columns, regrouping, selecting rows, sorting, etc. We need these features in our application. So we enabled many of them . But if during any client side activity in grid (like resizing columns) the timer fires to refresh the grid, the ajax request initiated by timer causes error inside one of Telerik WebResource .axd dynamic files and then the grid keeps to raise more errors or fails to continue to work and freezes. This is one of those errors but we get many different error types too:
Microsoft JScript runtime error: '_events' is null or not an object

It looks like DOM object gets corrupted after a timer ajax call during any client side function in RadGrid and it fails to handle error. Is there any way to recognize client activity before timer ajax request?

This is very important issue in our product and needs to be fixed as soon as possible. Please Help.

GridClientDeleteColumn Width is not staying set

Im creating a delete column in the codebehind like this:

if (hasRWPerm && UserSettings.CheckSetting(Page_UserSettings, Page_Cab.CabRealName, "deleteFolders"))

{

#region delete_folder

GridClientDeleteColumn btnDelete = new GridClientDeleteColumn();

btnDelete.ButtonType = GridButtonColumnType.LinkButton;

btnDelete.CommandName = DELETE;

btnDelete.Text = DELETE;

//btnDelete.HeaderText = "Deleted";

btnDelete.UniqueName = "deleteRow";

btnDelete.Resizable = false;

btnDelete.ShowInEditForm = true;

btnDelete.ItemStyle.Width = Unit.Pixel(50);

btnDelete.ConfirmText = "Do you want to delete this folder?";

RadGridCabFolders.MasterTableView.Columns.Add(btnDelete);

#endregion

}

it does what it needs to but if I click on my edit column or add a row the width of the delete column changes. I view the source and what I see is the <td style="width:50px;"> to <td> . Weird? or do you have a clue as to what is going on. Please do just send me to some random code sample, this has always been a waste of time.

Emailing Reminders - Any suggestions ?

Hi,

I would love to generate email reminders based on the reminder settings coming from my RadScheduler.

I imagine this would involved a scheduled application running on my server reading through the appointments in the database and checking for reminders and then sending emails.

Does anyone know of any examples or information available online that would help me develop this ?

Thanks
Sam

To find my problem in a RadGrid WebUserControl in a dll

Here is my situation.

I create a dll file that includes the name WebUserControl "EditRecord" and inside the WebUserControl, there is a RadGrid.

EditRecord is the Embed Resource DLL. At the exit I have this: ExampleCustomModule.dll.
Dll file is saved in the database. When necessary, I made the following code:

Dim assembly As System.Reflection.Assembly = System.Reflection.Assembly.Load(data)

Dim controlType As System.Type = assembly.GetType("ExampleCustomModule.EditRecord")

Dim myControl As Control = DirectCast(Activator.CreateInstance(controlType), Control)

When I check: myControl.Controls.Count it m'inidique I 0 control.

I'm putting as much control, there is nothing. I also try with: LoadControl (controlType, Nothing) but no success.

Have you any idea how I should do to recreate my control but also contains the controls inside?

Is my approach to backup my dll in the database is wrong or should I save in my bin?

Rad Grid Edit

When i click Edit Button in the radgrid and after edit is done when i click the Update or save button the system will check the list of existing tags to make sure the edited tag name does not already exist. This check will look at the exact name of all existing tags for that client and NOT be case sensitive.

If the edit being saved already exists, then a message will appear in red next to the tag name that says “The name you are trying to use already exists. No change has been made to your tag name.” The tag they tried to edit will still be in the tag list but with the original name.

How to do This?

Frozen checkbox button and relative positioning in IE 6

Hi there,

We are having the same issue in IE6 and IE7 as noted in the known issue link: known issue with buttons

We've been able to fix IE7 by adding relative positioning to the containing block as per the link above, however the same doesn't seem to work in IE6. Our pages are generated dynamically, so i've attached the output source structure. In IE7, we can add relative positioning style to the 'TabContent' class to resolve the issue. In IE6, this doesn't work.

Also noticed that the date picker button is having the same issue.

here is the inherited style for the anchor (<a>) on checkbox button
