RadGrid Drag/Drop Highlight

If you drag a row from one radgrid to an empty radgrid, there is no visual cue that you can drop the row. If there is already a row in the second grid, you get the drop line indicator.

Is there a way to show a visual cue when the grid is empty?

Thanks
Dwight

Multiple Edit Buttons on one grid

Hello, I have a two part question...I have a radGrid with an Edit LinkButton, this places the Grid into editting in-place...which is the desired effect. However I have a need to have a second Edit button (Push Button).
1. Can I have another Edit Button that also places the Grid into Edit mode via Popup.

2. While is popup edit mode can I place additional fields on the popup that are not one of the Grid Columns. Essentially I'd like to turn the popup into a Dialog box, the popup will capture some user input then when they click 'Update' I perform some operations using the data they inputted, Alternatively they can press cancel which would take them out of Edit mode.

Thank you

Available resources as appointments in Radscheduler

Hello all,

I was looking into having a resource that is available to be shown in the Radscheduler as a appointment or is there another way to show that a resource is available when looking at the Radscheduler. I have looked at some of the articles for special days, the problem I am looking to conquer is that if I have a appointment that is filled out with a name & resource, I want to show the rest of the appointment slots/Time slots for the day to show that the resource is available.

Thanks

Minify / Obfuscate release scripts?

Hi,

Minimizing the length of variable names would reduce the size of the scripts. Ditto for removing any redundant white space.

This would be really useful / helpful - to reduce initial page load times, etc.

Slider Items and Ticks don't appear in ToolTip

Using the Q3 2008 release of the slider control I encountered the rendering issue discussed in the knowledgebase and implemented the workaround (adding the repaint() call). The slider control now renders fine and appears to be working as expected - however, the Items and Ticks UI elements don't appear to be rendering at all.

Using the same markup on the page produces the desired results but when I move the code to "inside" the tooltip all of the item/tick UI elements no longer appear.

Anybody else see this behavior?

Filtering problem in Grid

Dear Support Team,

Filtering in grid still does not work when using ASP.Net 3.5 and Linq for columns having NULL values. While populating the grid data source is cached using the technique described in Boosting Performance with Linq.

This issue was reported in Case-Insensitive Search and Paging and was identified as bug. Based on the replies in that thread I reported to my client that this bug will be resolved in early November. However, only part of this bug is resolved in 2008 Q3 release as filtering still does not work with columns having NULL values.

UPDATE: The same grid cannot filter the NULL values correctly using SQLDataSource. IsNull and NotIsNull filters do not work.

I am now having serious issues with the client due to this filtering problem.

Please respond this issue immediately.

Best Regards,
Oner

Modify the "Show More" tag

Hi

I am using the Q2 version of the RAD Scheduler.
I have done settings so that MaxvisibleAppointments is 2 for all days, so if for any particular day number of appointment is more than
2 "Show More" link at the bottom of the cells comes up.

Is there any way to show the link like this : -- "Show More(8)" ---- where 8 is the number of more appointments.
That means if one day has 10 appointmnets then the cell will show 2 Appointments and the above mentioned link will
come up at the bottom of the day cell.

Thanks in Advance

Editing Hierarchical Sub Grid With LINQ Auto Methods - ID on Insert

When inserting a record on a sub grid in a two grid hierarchy using linq data sources and auto inserts/updates/deletes I'm getting a 0 for the parent record's id, which throws an error and doesn't insert the new record.

Editing and deleting work fine, but not inserting. I can manually override the insert command, check to see if it's the sub grid that's inserting, retrieve the id of the parent, and insert the record. But the auto Linq functionality doesn't work for me.

I've tried this many different ways and I can't seem to get this functionality to fly (inserting a record on a hierarchical sub grid with Linq auto method) in any configuration.

Code:

<telerik:RadGrid ID="ItemsGrid" Width="100%" Height="100%" Skin="Telerik" DataSourceID="ItemsDataSource" runat="server" AllowPaging="True" AllowSorting="true" PageSize="14" AutoGenerateColumns="false"
AllowAutomaticInserts="true" AllowAutomaticUpdates="true" AllowAutomaticDeletes="true">
<MasterTableView Width="100%" CommandItemDisplay="Top" DataKeyNames="Id"

<DetailTables>
<telerik:GridTableView DataKeyNames="Id, ItemId" DataSourceID="ItemCategoriesDataSource" Width="100%" CommandItemDisplay="Top" AutoGenerateColumns="false" runat="server">
<ParentTableRelation>
<telerik:GridRelationFields DetailKeyField="ItemId" MasterKeyField="Id" />
</ParentTableRelation>
<Columns>
<telerik:GridEditCommandColumn ButtonType="ImageButton" HeaderStyle-Width="20px" />
<telerik:GridBoundColumn DataField="Id" SortExpression="ItemCategoryId" UniqueName="ItemCategoryId" ReadOnly="true" Visible="false" />

<telerik:GridBoundColumn DataField="DateEntered" HeaderText="DateEntered" SortExpression="DateEntered" UniqueName="DateEntered" ReadOnly="true" DataFormatString="{0:d}" />
<telerik:GridButtonColumn ConfirmText="Delete this item?" ButtonType="ImageButton" CommandName="Delete" Text="Delete" />
</Columns>

<telerik:GridButtonColumn ConfirmText="Delete this item?" ButtonType="ImageButton" CommandName="Delete" Text="Delete" />
</Columns>
</MasterTableView>
</telerik:RadGrid>

<asp:LinqDataSource ID="ItemsDataSource" ContextTypeName="AppDataContext" TableName="Items"
EnableInsert="true" EnableUpdate="true" EnableDelete="true" runat="server" />

<asp:LinqDataSource ID="ItemCategoriesDataSource" ContextTypeName="AppDataContext" TableName="ItemCategories"
EnableInsert="true" EnableUpdate="true" EnableDelete="true" Where="ItemId == @ItemId" runat="server">
<WhereParameters>
<asp:Parameter Name="ItemId" Type="Int32" />
</WhereParameters>
</asp:LinqDataSource>

Any thoughts are greatly appreciated,

Seth
