invalid postback argument after custom filtering

Hi

I have radgrid with custom filtering:

<script type="text/javascript">

function IconsComboBoxChanging(sender, eventArgs) {

var item = eventArgs.get_item();

if (item != null) {

var input = sender.get_inputDomElement();

input.value = "";

input.defaultValue = "";

}

function DropDownFilterLoad(sender) {

sender.set_text("");

var itm = sender.get_items();

var selected = itm.getItem(sender._selectedIndex);

var img = selected.get_imageUrl();

var input = sender.get_inputDomElement();

SetBackground(input, img);

}

</script>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="true" OnNeedDataSource="CorrectionsGrid_NeedDataSource" [...]>

[...]

<Columns>

<telerik:GridTemplateColumn UniqueName="CorrectStatus" HeaderText="Status" HeaderStyle-Width="55px" Resizable="false" DataField="CorrectionAcceptState">

<ItemTemplate>

<asp:Image [...] />

</ItemTemplate>

<FilterTemplate>

<telerik:RadComboBox ID="StatusFiletCB" Width="45px" AppendDataBoundItems="true" DropDownWidth="205px" NoWrap="true" runat="server" OnSelectedIndexChanged="CorrectStatusFilterChange" AutoPostBack="true" AllowCustomText="false" OnClientSelectedIndexChanged="IconsComboBoxChanging" OnClientLoad="DropDownFilterLoad">

<Items>

<telerik:RadComboBoxItem Value="0"[...] />

<telerik:RadComboBoxItem Value="1"[...] />

<telerik:RadComboBoxItem Value="2" [...] />

</Items>

</telerik:RadComboBox>

</FilterTemplate>

</telerik:GridTemplateColumn

>

<telerik:GridTemplateColumn AllowFiltering="false" UniqueName="ActionColumn" HeaderText="" HeaderStyle-Width="60px"
    Resizable="false" Visible="false">
    <ItemTemplate>
       <asp:ImageButton CommandName="Reject" runat="server" CommandArgument='<%# Eval("CorrId") %>' Visible='<%# this.IsUserAllowedToAccept() %>' [...] />
    </ItemTemplate>
</telerik:GridTemplateColumn>

[...]

</Columns>

</telerik:RadGrid>

Code behinde:

protected void CorrectionsGrid_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

CorrectionsGrid.DataSource = new MyDataContext().Corrections;

}

private int? GetValueOfCorrectionAcceptStateFilter()

{

var regSearch = Regex.Match(CorrectionsGrid.MasterTableView.FilterExpression, @".*\(it\.CorrectionAcceptState = (?<filterVal>[1-3])\).*");

if (regSearch.Success)

return Int32.Parse(regSearch.Groups["filterVal"].Value);

else

return null;

}

protected void CorrectStatusFilterChange(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

string filterExpression = CorrectionsGrid.MasterTableView.FilterExpression;

var currentcFilter = GetValueOfCorrectionAcceptStateFilter();

if (currentcFilter.HasValue)

filterExpression = filterExpression.Replace("(it.CorrectionAcceptState = " + currentcFilter.Value + ")", string.Empty);

if (Int32.Parse(e.Value) > 0)

filterExpression = (filterExpression.Trim().Length > 0 ? filterExpression + " AND " : "")

+ "(it.CorrectionAcceptState = " + e.Value + ")";

CorrectionsGrid.MasterTableView.FilterExpression = filterExpression;

CorrectionsGrid.MasterTableView.Rebind();

}

everything works fine until I set the filter and call out rejection - invalid postback or callback argument. where making a mistake?

[Solved] RadGrid - Set row background color client side

I have a RadGrid that is based on the client edit with batch server update example code. I would like to change the background color of the row when the SelectedIndexChanged event fires in the RadComboBox in the currently edited cell of the grid row. I need to do this as a client side action. The currently edited row will be an ItemTemplate as the client edit with batch server update code doesn't use the EditItemTemplate when editing rows.

<telerik:RadComboBox ID="RadComboBankerRole"

runat="server"

OnItemsRequested="RadComboBankerRole_ItemsRequested"

OnClientSelectedIndexChanged="RadComboBankerRole_SelectedIndexChanged"/>

function RadComboBankerRole_SelectedIndexChanged(sender, eventArgs)

{

// Set row background color css class if selected value not string.Empty.

// Bonus points if you can apply different css class based on row index mod 2 ("zebra striped rows")

}

ImageEditorDialogs and EditorDialogs - how can I identify both in ExternalDialogsPath?

Hi,

I became aware just recently that a new folder called ImageEditorDialogs is now part of your release.
Should I be pointing to this in the ExternalDialogsPath parameter?
If so, how do I also point at EditorDialogs? I have made a change to the FileBrowser.ascx so I do need to point to this folder.
Can I merge the 2 folders? I notice that InsertImage.ascx exists in both.

Please advise.

Thanks

Jim

RadTimePicker error in DateInput

I define RadTimePicker as follow:

<telerik:RadTimePicker runat="server" ID="StartTime" Width="95%"

SelectedDate='<%# Bind("Start") %>'>

<DateInput ID="StartDateInput" runat="server" EmptyMessage="داده اجباری" DateFormat="HH:mm" EnableSingleInputRendering="false" />

<TimePopupButton />

<TimeView ID="StartTimeView" runat="server" Columns="2" ShowHeader="true" TimeFormat="HH:mm" HeaderText="از ساعت"/>

<DatePopupButton />

</telerik:RadTimePicker>

I set StartTime and EndTime on server side:

RadTimePicker startTime = (RadTimePicker)e.Container.FindControl("StartTime");

startTime.TimeView.StartTime = PatientScheduler.DayStartTime;

startTime.TimeView.EndTime = PatientScheduler.DayEndTime;

startTime.SelectedTime = e.Appointment.Start.TimeOfDay;

Based on PatientScheduler:

<telerik:RadScheduler runat="server" ID="PatientScheduler" Width="100%" Height="100%"

DataSourceID="PatientAppointmentsEntityDataSource" DataKeyField="Id" DataSubjectField="Subject"

DataStartField="Start" DataEndField="End" FirstDayOfWeek="Saturday" HoursPanelTimeFormat="HH:mm"

LastDayOfWeek="Thursday" EditFormDateFormat="yyyy/MM/dd"

Skin="Office2010Blue">

I have two problems in this project:
1. When I run web and select 3:00(Time is based on 24 Hours), displayed 11:00 in DateInput. When select 9:00, Displayed 17:00 in DateInput.
2. I can just select time from 00:00 to 9:00 and it displayed from 8:00 to 17:00 because PatientScheduler is from 8:00 to 17:00
