Scheduler Not Updating When Filtering With No Data Returned

I have a Scheduler bound to an ObjectDataSource that I want to filter using a dropdown list of Categories. I have a ControlParameter as a SelectParameter on the ObjectDataSource tied to this dropdown. My filtering works fine if I select an Category that has appointments associated with it and actually returns rows. However, if I select a Category that does not have any appointments associated with it and returns no rows, the Scheduler never updates and continues to show the previous list of appointments instead of showing no appointments. Any idea on why the Scheduler won't refresh and properly show no appointments in this situation?

RadAsyncUpload auto fire selection of files

I am working on my own styling of this control because I want it displayed in a small form center of the screen.

Formatting the "select" button is a little limited and therefore I want to have my own button outside of the actual control itself to fire the selection of files.

The idea is that when my button is clicked it triggers the RadAsyncUpload control to fire up a dialog to select files using the File Explorer.

I can't see a method that I can call on the client side for this.

Is this even possible?

I have tried styling the button with an image but it is irratic, the div doesnt extend to show the larger image and it all looks a mess.

If I localise the value to something longer than the word "select" then it flows outside the standard button.

can anyone offer a suggest as to how to either trigger the selection of files from my own button or substantially style the RAD button to something larger and perhaps image based?

thanks

Access Value in CommandItemTemplate During NeedDataSource

Hello All,

I'm having problems accessing a value in the OnNeedDataSource event. The value is a textbox in the CommandItemTemplate. I'm using it as a custom filter while building the datasource. I've done this before but forgot how I did it. :( It seems that during the OnNeedDataSource the CommandItemTemplate has not been created yet.

Thanks,
Jerry

RadGrid GridDropDownColumn validations

Hi,

I'm quite new with asp and telerik components, so I need some help to figure this out:

i'm trying to validate GridDropDownColumns that hold Combobox's and check is text area of combobox filled with value from dropdown.

Now my problem is when I try to add custom validator in cs code side, it doesn't fire serverside validation. I don't want to add templatecollums to my grid if it's not necessary.

in itemDataBound:

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem item = e.Item as GridEditableItem;

if(item["content"].Controls[0] is RadComboBox)

{

GridDropDownListColumnEditor editor = item.EditManager.GetColumnEditor("content") as GridDropDownListColumnEditor;

TableCell cell = (TableCell)editor.ComboBoxControl.Parent;

CustomValidator validator = new CustomValidator();

validator.ServerValidate += new ServerValidateEventHandler(comboboxValidations_ServerValidate);

validator.ValidationGroup = "comboGroup";

validator.ErrorMessage = "!";

validator.ValidateEmptyText = true;

validator.ControlToValidate = editor.ComboBoxControl.ID;

cell.Controls.Add(validator);

}

Server side function not running

Hi

I have a RadGgrid witht he following template section:

<telerik:GridTemplateColumn HeaderText="Arrival" SortExpression="LocationArrival" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" AllowFiltering="false" UniqueName="LocationArrival">
<ItemTemplate>
<asp:CheckBox ID="chkActivityArrival" runat="server" AutoPostBack="True" visible="false" OnCheckedChanged="chkActivityArrival_CheckedChanged"/>
</ItemTemplate>
</telerik:GridTemplateColumn>

However when I click the checkbox the function chkActivityArrival_CheckedChanged on the server isn't being hit. The controls visibility is controlled in the code behind.

I have the same code n other grids and they work OK, what would be causing this..

Multiselect check box column behaves inconsistently with paging

I'm trying to setup a grid with paging, filtering, grouping and multiselect turned on, including the check box column for selection. I understand that when paging and filtering, any existing selected rows will become unselected. But when I page through a grid, the row select check box column seems to become disabled - we cannot check rows to be selected after paging. Drag and drop selection continues to work and the "select all" check box still works, but the check boxes to select individual rows do not.

I have tried simplifying our grid setup to one with just multiselect and paging but the issue remains.

Also of note we are still using a 2012 release of Telerik UI for ASP.NET AJAX. We intend to update to the latest 2014 release in the next release of the software we are delivering to our client, but will need to continue to use the 2012 Telerik UI release for the current release of the client's software.

So is this a known issue with the 2012 releases of the grid UI? Is there any known fix besides upgrading to a later version of Telerik UI?

Thank you,

Eric
