DataRecurrenceField

We are using a third party control to develop the scheduler functionality in our application. But with that we are not able to show the appointments in a different color based on the appointment status. I have seen your online Demos and I saw RadScheduler is a perfect suit for our requirements.

We had recurring appointments and we were rebinding our control to the datatable on the next day or previous day button click events.

RadScheduler was not showing anything even I have an appointments exists for next day/previous day. I tried rebinding the datatable to the Scheduler from RadScheduler1_NavigationCommand Event but it still showing nothing. Is there anyway that I can make this workout without using DataRecurrenceField and DataRecurrenceParentKeyField ?

Programmatically Wireing Event handler on a loaded control.

Good Afternoon,

I am trying to wire up the ItemDataBound event of the RadListView control and encountering issues doing so. Let me describe the situation.

I am building a custom Sharepoint webpart that loads a control from an aspx page using Page.LoadControl. The loaded aspx page contains the RadListViewControl whose events I wish to wire up.

    
            _ctrlGoogleCalendarSubscriptions = Page.LoadControl("/_controltemplates/NUGoogleCalendarSubscriptions.ascx");

To wire up the event I call;

    
            _radCalendarListView.ItemDataBound += new EventHandler(this.radCalendarListView_OnItemDataBound);

I do this in the CreateChildControls method.

However when I compile I recieve the error "No overload for 'radCalendarListView_OnItemDataBound' matches delegate 'System.EventHandler'"

The method I am passing is below,

    
                    protected void radCalendarListView_OnItemDataBound(object sender, Telerik.Web.UI.RadListViewItemEventArgs e)  
        
                    {  
        
                    }

I am able to wire up the DataBinding event without issue.

Am I missing something, is this not possible with the Rad Controls when loaded in this fashion?

Please let me know if you need any further details at all.

Regards,

Christian Brown

Grid delete column command

I have a grid that is subclassed from the telerik grid control. It is declared like this on the page

ID

="NotarySearchResultsGrid" runat="server" AutoGenerateColumns="false" OnNeedDataSource="NotarySearchResultsGrid_NeedDataSource"

OnItemCommand="NotarySearchResultsGrid_ItemCommand" AutoGenerateDeleteColumn="false" AutoGenerateEditColumn="false"

AllowDelete="false" AllowEdit="false" AllowInsert="false" AllowSorting="true"

ShowViewDetailsCommandColumn="false"

AllowPaging="true" PageSize="100" PagerStyle-Position="Bottom" PagerStyle-Mode="NextPrevAndNumeric"

>

<telerik:GridButtonColumn HeaderText="Commission #" UniqueName="CommissionNumberColumn" ButtonType="LinkButton" DataTextField="CommissionNumber"

CommandName="CommissionSelected" SortExpression="CommissionNumber" ></telerik:GridButtonColumn>

<telerik:GridBoundColumn HeaderText="Name" UniqueName="NotaryNameColumn" DataField="Name" SortExpression="Name"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Address" UniqueName="AddressColumn" DataField="Address" SortExpression="Address"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="City" UniqueName="CityColumn" DataField="City" SortExpression="City"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Zip" UniqueName="ZipColumn" DataField="Zip" SortExpression="Zip"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="County" UniqueName="CountyColumn" DataField="County" SortExpression="County"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Status" UniqueName="StatusColumn" DataField="Status" SortExpression="Status"></telerik:GridBoundColumn>

</Columns>

<div>

No records to display.

</div>

</NoRecordsTemplate>

</MasterTableView>

However, when the grid displays, there is an extra column at the end of the grid. Looks like a hyphen or the beginning of an underline in the column header area but no data in the column. Using the IE dev toolbar, I'm able to see tha tthe UniqueName for this column is DeleteCommandColumn. Both AllowDelete and AllowAutoGenerateDelete columns are set to false in the code above. Is there another setting I can set too? Nothing jumped out at me.

Thanks,
Dennis

[Solved] column group header

I want to create column header groups. and am not able to find an example of anything close to what I'm trying to do.

I need to group repeating set of columns, and the grid is resizeable, so it would be optimal to have these headers generated within the grid headers, but have no idea how this would be best accomplished.

I've attached a sample visual which I think will explain better than words.

Change skin of Tabstrip using javascript

I have a tabstrip on an .aspx page. I have created a custom skin for this and set it during design time. But during runtime, when the user clicks on a button on the page, I want to change the skin. I want to do this in javascript. Right now, I am using javascript to change the background color of the tabstrip. But the currently selected tab's background is not getting changed to the color of the background. Could you please help?

Thanks,

MS

controls in toolbox

Okay, so I just downloaded and installed the new version of the Rad controls. When I open my web site projects, I can see all the new rad controls in the toolbox. My problem is with one particular website (uses way older rad control version), none of the rad controls are in the toolbox whatsoever. I even go into the choose items and find the web.UI, but nothing shows up. I also ran the toolbox program in telerik and still nothing shows up. So, I find it really strange that all the new controls are showing up in most of my websites and not this one. any ideas or suggestions as to why this is happening?
