hide GridEditCommandColumn if not an admin

Hi,
Trying to find a way to hide the
<telerik:GridEditCommandColumn UniqueName="EditCommandColumn" EditText="Notes"></telerik:GridEditCommandColumn>
if a person doe snot have admin privledges, I see lots of examples for other buttons and controls but so far not this way.

Protected Sub myRadGrid_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles myRadGrid.ItemDataBound

If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode Then

Dim EditFormcmdItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

If checkAdmin() = False Then

EditFormcmdItem.FindControl("EditCommandColumn").Visible = False

End If

End Sub

Two-way Declarative Binding to DataTable

Hi,

I am referring the below link,
http://www.telerik.com/help/aspnet-ajax/grid-binding-description-bind-method.html

two way binding at RadGrid, and I am currently migrating the GridView to RaidGrid, which GridView Application was using bind method to DataTable and save it DataBase, You may refer the below link,

http://www.telerik.com/community/forums/aspnet-ajax/grid/radgrid-binding-to-datatable.aspx

and My question is,

1. ItemUpdated event was not fired, does it support? if not, any alternative solutions?
2. which event can be traced when data has been updated to the DataSource by using the above Two-way Declarative Binding approach?
3. Do we need to explicit update the value from RadGrid to DataSource (e.g DataTable)? for GridView, there is a function call gridView.UpdateRow to upate to DataSource.
4. As I have plenty of logic monitoring the dataTable dataChaning event for data validation, conditional data retrieving,calculation and so, it is painful if bind to DataTable is not working for GadGrid, Any Suggest for me?

Thanks.

Multiview Calendar - Hide some months?

I have a Multiview calendar which is set by default to show 1 year, in 4 columns and 3 rows.

I have 2 other DatePickers on the page that let the user pick a start and end date.

Based on the range selection in the 2 datepickers, I would like to hide unused months in the Multiview calendar. For instance, I show 12 months by default in Multiview, but if you select a range of April to August, then I would like to show the first row of 4, but then only 1 month calendar in row 2 - effectively hiding the last 7 months. All of this to be done dynamically on the server-side.

I can't seem to find a way to do this. Any one?

Document Manager and Filenames with non-printable characters

Hi,

Today we had an interesting problem that I'm hoping you'll be able to help me fix.

One of our clients, using the Rad Editor (ASP.NET), clicked on the Document Manager and the listing displayed no files.

However the folder that was being accessed had 77 files.

Upon trying to find out why they weren't being displayed, I discovered that one of the file names had a non-printable character in it.

So, once I renamed the file the listing of files worked fine.

The question is:
How do I fix the filenames of files being uploaded so that files are not stored on our servers that may contain non-printable characters?
And
Even if they do contain non-printable characters, how do I get the Document Manager to display the folder of files anyway (with or without the offending file)?

Thanks,
Cameron

Bind control when filtering

So using the RadControl, I think I managed to get it to filter the datetime correctly so it can only do Dates even when times are included in the data source.This is calling the OnItemCommand event for the control.
But, when I do a datasource and a bind(), no results are shown even though the data does exist in the datasource

The control does filtering based on AJAX Requests I believe so how can I follow this convention?
At the end of the day, The data in this scenario is being filtered on the server end and wish to rebind this.

or alternatively, can someone tell me how I can do the date filtering on clientside using the GridDateTimeColumn, so I can obtain the FilterType and the current selected date then finally do a filter?

Thanks

GridBoundColumn DateTime javascript error on between filter.

I am attempting to apply a date range filter to a GridBoundColumn bound to a DateTime.

<telerik:GridBoundColumn DataField="Created" FilterControlAltText="Filter Created column"

HeaderText="Created" SortExpression="Created" UniqueName="Created">

<FilterTemplate>

<telerik:RadDatePicker ID="ToCreatedDatePicker" runat="server" Width="85px"

MinDate="01-01-2012" DbSelectedDate='<%# EndCreatedDate %>' ClientEvents-OnDateSelected="ToDateSelected"/>

to

<telerik:RadDatePicker ID="FromCreatedDatePicker" runat="server" Width="85px"

MinDate="01-01-2000" DbSelectedDate='<%# StartCreatedDate %>' ClientEvents-OnDateSelected="FromDateSelected"/>

<telerik:RadScriptBlock ID="scriptFilterEventDate" runat="server">

<script type="text/javascript">

function FromDateSelected(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

var ToPicker = $find('<%# ((GridItem)Container).FindControl("ToCreatedDatePicker").ClientID %>');

var fromDate = FormatSelectedDate(sender);

var toDate = FormatSelectedDate(ToPicker);

if (toDate != '') {

tableView.filter("Created", fromDate + " " + toDate, "Between");

}

function ToDateSelected(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

var FromPicker = $find('<%# ((GridItem)Container).FindControl("FromCreatedDatePicker").ClientID %>');

var fromDate = FormatSelectedDate(FromPicker);

var toDate = FormatSelectedDate(sender);

if (fromDate != '') {

tableView.filter("Created", fromDate + " " + toDate, "Between");

}

function FormatSelectedDate(picker) {

var date = picker.get_selectedDate();

var dateInput = picker.get_dateInput();

var formattedDate = dateInput.get_dateFormatInfo().FormatDate(date, dateInput.get_displayDateFormat());

return formattedDate;

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

</telerik:GridBoundColumn>

When the filter is applied I receive the following error message from javascript console.

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: String was not recognized as a valid DateTime.

Sys.WebForms.PageRequestManager._endPostBackTelerik.Web.UI.WebResource.axd:15

(anonymous function)Telerik.Web.UI.WebResource.axd:6

Sys.Net.WebRequest.completedTelerik.Web.UI.WebResource.axd:6

_onReadyStateChange

The filter is not applied when this error is received

Any idea what I'm doing wrong here..

Filtering between dates

Hi.
Following some examples, I found this:

http://www.telerik.com/community/code-library/aspnet-ajax/general/filtering-range-with-raddatepicker-instances-in-a-custom-filtering-column.aspx

I am trying to filter a data source between 2 selected dates.

I am almost there with the implementation of the solution however the problem is, even when the dates are selected, the SelectedDate on the ItemCommand event is null (Nothing in VB.NET)

any ideas where I have gone wrong?

<telerik:GridTemplateColumn HeaderStyle-HorizontalAlign="Center"

HeaderText="DateFilter" SortExpression="DateTime" UniqueName="DateFilter"

AllowFiltering="true" ShowFilterIcon="true" AutoPostBackOnFilter="false" DataType="System.DateTime"

DataField="DateTime" ItemStyle-HorizontalAlign="Left">

<HeaderStyle Width="90px"></HeaderStyle>

<ItemStyle HorizontalAlign="Left" Width="90px"></ItemStyle>

<FilterTemplate>

<telerik:RadComboBox ID="ddlDateFilter" runat="server" DropDownWidth="200px">

<Items>

<telerik:RadComboBoxItem Text="" Selected="true" />

</Items>

<ItemTemplate>

From <telerik:RadDatePicker ID="RadDatePickerFrom" runat="server" onclick="PreventDropDownClose(event);">

</telerik:RadDatePicker>

To <telerik:RadDatePicker ID="RadDatePickerTo" runat="server" onclick="PreventDropDownClose(event);">

</telerik:RadDatePicker>

<asp:Button ID="cmdFilterDates" runat="server" Text="Filter" CommandName="FilterDates" />

</ItemTemplate>

</telerik:RadComboBox>

</FilterTemplate>

</telerik:GridTemplateColumn>

Code:

Protected Sub grdShiftObservation_OnItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles grdShiftObservation.ItemCommand

If String.Equals(e.CommandName, "filterdates", StringComparison.OrdinalIgnoreCase) Then

Dim cell As TableCell = CType(e.Item, Telerik.Web.UI.GridFilteringItem)("DateFilter")

Dim dateFilterComboBox As RadComboBox = CType(cell.Controls(0).FindControl("ddlDateFilter"), RadComboBox)

Dim dateFrom As RadDatePicker = CType(dateFilterComboBox.SelectedItem.FindControl("RadDatePickerFrom"), RadDatePicker)

Dim dateTo As RadDatePicker = CType(dateFilterComboBox.SelectedItem.FindControl("RadDatePickerTo"), RadDatePicker)

End If

End Sub

dateFrom and dateTo show "Nothing"

any ideas? I want to be able to obtain the dates the user has selected.
