Server Error when sorting from server-side

Greetings,
I have a RadGrid within a CompositeControl (along with a couple RadMenus and some other controls). I store a user's column visibility and sort preferences serverside and manually add the columns and sortexpression when a grid is loaded. The error I am getting is:

Unable to cast object of type 'Telerik.Web.UI.GridImageButton' to type 'System.Web.UI.WebControls.Button'.

which occurs Only when I add my own sortexpression to the mastertableview during Grid.Init (after all the columns have been added). If I comment out the

Grid.MasterTableView.SortExpressions.AddSortExpression(sortExp);

then everything works as expected, but I don't get my sort, of course.

I have tried setting Col.ShowSortIcon to false but that did not change anything. I have also played with different values for Col.HeaderButtonType, also without change.

Any insight would be greatly appreciated.

Thanks,
- Forrest

Failed to load viewstate after closing radwindow

Hello,

I am getting an error with the viewstate. I need to do some stuff in the code behind of the child radwindow prior to closing it. Then I need to do some other tasks on the parent form. After I click the close window of the child radwindow and then click the button on the parent form I get the message "Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request. " I am new to this and have read the __doPostBack, but am not sure if I need that or where to start. I would appreciate any insight. I have supplied the code below. Thanks.

Drop down with check marks

I would like to configure a drop down button on the tool bar that has items that can be checked (selected) or unchecked. The visual appearance would show the check/unchecked status. I figured this might be common enough that you had a sample lying around somewhere or could point me in the best direction.

Regards,
Bob

RadEditor command history

Hi,
I have noticed that there are a few stings appearing in command history (undo) of the radeditor which don't seem to be in any of the resx files. Specifically "Unlink" and "Insert HTML". Is there a way to localize these strings?

Thanks

Checkbox not aligning properly

I am using a checkbox that needs to align right

<td style="align:right;"><checkbox></td>

it works fine but as soon as I drop the FormDecorator on the page, it aligns left (all other controls - ddl and txt align properly).

Any reason for this?

also note. i put the formdecorator control on the masterpage and not directly in the form.

Export option in radgrid

I have a radgrid which is

<radG:RadGrid TabIndex="11" ID="RadGrdFiltered" Skin="Glassy" EnableAJAX="True" AutoGenerateColumns="False"

LoadingTemplateTransparency="20" ItemStyle-Height="20px" AlternatingItemStyle-Height="20px"

AllowMultiRowEdit="false" AllowMultiRowSelection="true" MasterTableView-RetrieveAllDataFields="true"

EnableOutsideScripts="false" EnableAJAXLoadingTemplate="false" runat="server" AllowSorting="false"

AllowPaging="true" PageSize="10">

<MasterTableView Width="100%" HorizontalAlign="NotSet" AutoGenerateColumns="false"

AllowAutomaticDeletes="True" CssClass="master">

<radG:GridBoundColumn HeaderText="ID" ItemStyle-HorizontalAlign="left" ItemStyle-VerticalAlign="Middle"

DataField="ID" SortExpression="ID" HeaderStyle-Width="10%" />

<radG:GridBoundColumn HeaderText="First Name" ItemStyle-HorizontalAlign="left" ItemStyle-VerticalAlign="Middle"

DataField="First Name" SortExpression="First Name" HeaderStyle-Width="12%" />

<radG:GridBoundColumn HeaderText="Last Name" ItemStyle-HorizontalAlign="left" ItemStyle-VerticalAlign="Middle"

DataField="Last Name" SortExpression="Last Name" HeaderStyle-Width="12%" />

<radG:GridBoundColumn HeaderText="Plan Type" ItemStyle-HorizontalAlign="left" ItemStyle-VerticalAlign="Middle"

DataField="Plan Type" SortExpression="Plan Type" HeaderStyle-Width="12%" />

<radG:GridBoundColumn HeaderText="Status" ItemStyle-HorizontalAlign="left" ItemStyle-VerticalAlign="Middle"

DataField="Status" SortExpression="Status" HeaderStyle-Width="12%" />

<radG:GridBoundColumn HeaderText="Division" ItemStyle-HorizontalAlign="left" ItemStyle-VerticalAlign="Middle"

DataField="Division" SortExpression="Division" HeaderStyle-Width="12%" />

<radG:GridBoundColumn HeaderText="Department" ItemStyle-HorizontalAlign="left" ItemStyle-VerticalAlign="Middle"

DataField="Department" SortExpression="Department" HeaderStyle-Width="12%" />

<radG:GridBoundColumn HeaderText="Location" ItemStyle-HorizontalAlign="left" ItemStyle-VerticalAlign="Middle"

DataField="Location" SortExpression="Location" HeaderStyle-Width="32%" />

</Columns>

</MasterTableView>

</radG:RadGrid>

Now I tried to export the data in the radgrid to excel using a button click event. The event is

protected

void btnExport_Clicked(object sender, EventArgs e)

{

RadGrdFiltered.ExportSettings.IgnorePaging =

true;

RadGrdFiltered.ExportSettings.OpenInNewWindow =

true;

RadGrdFiltered.MasterTableView.ExportToExcel();

RadGrdFiltered.ExportSettings.FileName =

"QBOutput" + DateTime.Now.ToFileTime() + ".xls";

}

But inspite of giving these things, i am not able to achieve the result.

Sheduler across 5 year

hi,
I am using the sheduler for 5 year planning and was wondering how to present the data nicely. Since i am using timeline and have set the width to 3200px, i found that it is difficult to identify the appointments with its related year. I was wondering that if i could highlight the time slot for every year with different colors or you can provide other alternatives to improve the view.
The details are shown as following:
<TimelineView
GroupingDirection="Vertical" HeaderDateFormat="MM/yy" NumberOfSlots="60" SlotDuration="31.00:00:00" GroupBy="Generation" />

regards,
Chun

[Solved] Appointment Creation

Hi,

When double clicking to create an appointment, I want the appointment to just appear without having to enter an appointment name or click the green tick box. Also, I dont want the facility to edit the appointment, just to be able to move it and delete it.

I'm using the scheduler as part of a weekly schedule, and the appointment text is retrieved from the database. The user shouldnt have the option to change this.

Is this possible?

Thanks,

Scheduler
