hi,

I have a gantt chart, when i perform inline edit through an ajax call for the end date the date gets changed but the scheduler part remains the same. It gets changed only when a refresh of the page is done.

I want the scheduler to get changed when the end date is changed through ajax call without  read event of the data source or a page refresh.

Can i get to know how this requirement can be achieved?

Thanks

I am using RadGrid's RowDrop feature to allow my users to rearrange rows in the grid.  

In the business logic, I use a table column to store a sort index for each row, and when I get a RowDrop event, I calculate the row's new index based on the target row, update the database and refresh the Datasource.  This works really well for me as long as the row is dropped on or before the last visible row in the grid.

However, my users are confused when they drop a row past the end of the last visible row and the refreshed grid shows that dropped row preceding the last row, rather than it becoming the new last row.

 How can I detect when the row is dropped in the empty space of the grid?

 I found that GridDragDropEventArgs has a member "DropPosition" which appears to be undocumented; in any case, this value (enum Above or Below) does not appear to be consistent with what non-Telerik documentation I've seen, so it's not a reliable way to detect if the user dragged past the last row or not.

 Any other ideas?

I've got a combobox that updates a grid, but the grid's NeedDataSource handler isn't invoked when the AJAX request happens.  However, when I click the refresh button on the grid it issues another AJAX request and this one does invoke the NeedDataSource handler.  Can anyone help me understand why this isn't happening in the former case?

I call a database to populate my RadCombobox with ID, CategoryName, BackgroundColor, TextColor
how can I change each option in the drop down to use these options.
my current combobox is a listing of checkboxes.

I already have written out css classes for each one and possibly all I need to do is set each option's css class.
How to do?

I have a datagrid that contains a column which has an editable drop down list.

I have filtering set to true, but when you place text in the filter box and click "Equal To" or whatever clause, it breaks/errors out

I get Unhandled Exception error.  Its a messing popup window with a bunch of jargon.

 

Anything I need to alter to make this work with that EditTemplate piece in there?

 

Here is the code

 

    <telerik:GridTemplateColumn HeaderText="ConfirmationType" ItemStyle-Width="240px" AllowFiltering="True" ShowSortIcon="True">
                        <ItemTemplate>
                            <%#DataBinder.Eval(Container.DataItem, "ConfirmationType")%>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadComboBox RenderMode="Lightweight" runat="server" ID="RadComboBox1" DataTextField="ConfirmationType" DataValueField="ConfirmationType" DataSourceID="ConfirmationType" SelectedValue='<%#Bind("ConfirmationType") %>'>
                            </telerik:RadComboBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

Hi,

i have an issue with the grouping functionality of RadGrid.
There is a grid with several items.
Each element is custom object and is bind via "RadGrid.Datasource".
Everything works fine and all items are shown in the Grid if there is no grouping.
But after i am enabling grouping and set following SelectFields & GroupByFields only the first group and his first element is shown in the grid.
<GroupByExpressions>
    <telerik:GridGroupByExpression>
        <SelectFields>
            <telerik:GridGroupByField FieldAlias="Bundle" FieldName="GroupName" HeaderValueSeparator="_" />
        </SelectFields>
        <GroupByFields>
            <telerik:GridGroupByField FieldName="GroupName" SortOrder="None"/>
        </GroupByFields>
    </telerik:GridGroupByExpression>
</GroupByExpressions>

I use the debugger and search for an error but everything looks fine and all items are bind to the datasource.
But only the first group is shown in the grid and from this first group only the first item.
The title of the group is like "Bundle_Truck7546 (Showing 1 of 3 items. Group continues on the next page.)" but the PageSize is at 50 and there is no next page.

I hope anyone know what cause this problem and how i can solve it.

If you need further information please post.

best regards

Hi, i have a problem similar to a thread which was raised earlier last year (http://www.telerik.com/community/forums/aspnet-ajax/scheduler/radscheduler-in-ie8-compatibility-mode.aspx)

I currently have a problem displaying the scheduler on our local intranet website where the scheduler will be shown incorrectly only on internet explorer.

The page consists of one screen with a scheduler which should take up the whole space, but with Internet Explorer 9, it seems to get squished to the left hand side of the browser. After checking the internet tools, it seems that even though the document mode is forced to IE9, the browser mode is by default on "IE9 compatibility mode" which is what seems to be causing the problem.

I have done research to see if i can turn off the compatibility mode programmatically but to no avail.

One workaround i found was, even if the browser mode is on IE9 compatibility mode, if i had the document mode to be on IE7, the scheduler renders near correctly (the scheduler takes up the whole screen space but the grid lines are mis aligned with the dates on top) but the checkboxes i need are not rendered.

Is there any solution to fixing this problem or get a better working workaround? It is going to be difficult to explain to users to go into their internet explorer settings to stop forcing of compatiblity view on their browsers.

I want to initialise the grid from the code behind.

Hi,

I am creating a multiple ComboBox. RadComboBox1 for region and the other RadComboBox2 for product. Both controllers have a checkbox option. Sample data as per below;

RadComboBox1;

B
C

RadComboBox2;

3

What do I need are, when user choose Region [A,C] and product [1,2,3], the result would be [A1,A2,A3,C1,C2,C3]. Please help.

 

Thanks.
