Hello,
I have a solution contains radgrid in witch there are also template columns.
Calling the ExportToExcel method from a button event of export falls with the error:
"Object refernce" in pre-render of grid event, because of hiding the checkbox column.
And even if i skip the per-render code by flag, the export doesnt work.
Actually the export doesnt work and my grid on screen has no checkbox anymore but "false" in the column.
I have tried hiding the column, but nothing helps.
I have spent many hours reading same problems but none of the solutions helped me.
I also tried putting standard code of exporting, like gridview (with response and htmltextwriter) but it falls with error:

יש למקם את הפקד '

ctl00_contentBody_gridInviteds_ctl00_ctl02_ctl00_ctl00' מסוג 'GridLinkButton' בתוך תג טופס עם runat=server.

Actually, when my grid is with no template columns, the export is working but still there is a poblem that the headers have a button in the excel sheet, even though i wrote in code "allowSorting=false"

thanks,
gila

Fitlering/Sorting List of Object Column?

Hey,

I have a Linq to Sql data object which has 2 classes called Topics & Posts. Each topic can have multiple posts, thus, there is a one to many relationship from topic to posts.

I have the RadGrid bound to a LinqDataSource object which returns all topics, and topics can access all posts under that topic, ie topics(x).posts(y).subject etc.

In the RadGrid, for testing purposes, I am binding the first post as the subject of the topic, for example:

<telerik:GridBoundColumn DataField="posts(0).post_subject" DataType="System.String"

FilterControlAltText="Filter column" HeaderText="post_subject"

UniqueName="post_subject" SortExpression="posts.post_subject">

</telerik:GridBoundColumn>

This works fine, and displays the information in the grid correctly, but, if I do any type of sorting/filtering I get the following error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: No property or field 'post_subject' exists in type 'EntitySet`1'

I've tried different variations of the SortExpression but still get a similar error.

Is there a way to achieve this?

Thanks

Calender navigation not working when MultiViewRows or MultiViewColumns > 1

I have the following properties set on a RadCalendar:
MultiViewRows = 2
MultiViewColumns = 2
FastNavigationStep = 3
EnableMultiSelect = true
EnableMonthYearFastNavigation = true
RangeMinDate = new DateTime(2010, 1, 1)
RangeMaxDate = new DateTime(2012, 1, 1)

The navigation arrows in the title bar do not work in any browser. When I click on them, nothing happens. I do not see any javascript error.

If i change MultiViewRows and MultiViewColumns both back to 1, then the navigation arrows work OK.

If either MultiViewRows or MultiViewColumns are above 1, then the navigation arrows stop working. Clicking on the title and selecting the month/year from the popup panel also doesn't work.

I am using version 2010.3.1317.40.

Any help would be appreciated.

Edit Form Template

I could do with some more help.

In my RadGrid I have created a custom edit form using the template mode and I have captured the update command event to intercept the update as i want to write the information entered by the user manually to my database.

In the update command event I have converted e.item to a GridEditFormItem and now I want to get access to the controls that i have added into my template. There seems to be lots of controls embedded in this item so is there an easier to access the data entered by the user. I have a RadTextBox and RadDateTimePicker.

Thankyou.

Scheduler Navigation Controls do not work

Hi, I have scheduler databound to a sql datasource successfully. In the NavigationCommand I am getting the type of navigation and then changing the Scheduler's selected date like this

RadScheduler1.SelectedDate = CurrentDate.AddDays(1)

But this does not affect the selected date. I am in DayView so I just want the calendar to advance 1 day but this does not work. I have tried issuing the rebind command but that does not work either. I think I am not understanding how the scheduler binds to its data in this situation. I see appointments, I just cannot navigate using the upper left corner navigation controls. Any clarification on this would be most welcome.
