Error in RadGrid when using RadDatePicker and KeyboardNavigation

Hello,
I have created a RadGrid that uses KeyboardNavigation for making changes. Two of my columns are dates and use RadDatePickers for inline editing. My third column is just a Notes column (text box).
When I hit [Enter] to put a row into Edit Mode, move to the Notes text box and hit [Enter] I can save the row, or if I hit [Escape] I can cancel the edit.

If, however, my focus is on one of the two RadDatePickers and I hit [Enter] or [Escape] I get the following error:

Text property cannot be set. String was not recognized as a valid DateTime.
[InvalidCastException: Text property cannot be set. String was not recognized as a valid DateTime.]

Problem with GridnumericColumn and tab key

I have a Radgrid with a couple of numeric columns. The grid is in multi-edit mode, and when the user hits Save button, I loop through the grid, and call GridEditableItem.ExtractValues to get the values to save back to the database.

The issue is that when a user is entering a value in the textbox (for the gridnumericcolumn) and does not tab off that textbox and hits the save button, the value does not get saved. If the user tabs off, the entered value is formatted and when the user hits Save button, value gets saved as expeced. The issue is easily reproducible. I am using Telerik v2.0.50727

The markup is:
<telerik:RadGrid Skin="Web20" ID="RadGrid1" runat="server" OnItemCreated="RadGrid1_ItemCreated"
    OnItemDataBound="RadGrid1_ItemDataBound" OnNeedDataSource="rgTasks_NeedDataSource"

    <MasterTableView HierarchyDefaultExpanded="true" HierarchyLoadMode="Client" ShowFooter="false"

                    ShowRefreshButton="False"></CommandItemSettings>
        <RowIndicatorColumn Visible="True" FilterControlAltText="Filter RowIndicator column">

GridDateTimeColumn default filter

Hello,
I am using in my RadGrid following code:

<telerik:GridDateTimeColumn FilterControlWidth="140px" DataField="Datum" HeaderText="Datum"

SortExpression="Datum" UniqueName="Datum" PickerType="DateTimePicker"

EnableRangeFiltering="true" CurrentFilterFunction="Between" ReadOnly="True" AllowFiltering="True" FilterListOptions="VaryByDataType">

<HeaderStyle Width="220px" />

</telerik:GridDateTimeColumn>

When I click on filter icon I get list of options like (between, not between etc...) Would it be possible to have always one default value there (between) and use it after clicking to filter icon?

Binding to generic list of objects

Hi I have a generic list of objects that I would like to bind to a bar graph that have the following properties:

public decimal TotalValue

{

get

{

return _totalValue;

}

set

{

_totalValue = value;

}

public decimal TotalHours

{

get

{

return _totalHours;

}

set

{

_totalHours = value;

}

public string FieldActivityNameWUnit

{

get

{

return _fieldActivityNameWUnit;

}

set

{

_fieldActivityNameWUnit = value;

}

public int ActivityMonth

{

get

{

return _activityMonth;

}

set

{

_activityMonth = value;

}

public string ActivityMonthName

{

get

{

return _activityMonthName;

}

set

{

_activityMonthName = value;

}

public string FieldActivity

{

get

{

return _fieldActivity;

}

set

{

_fieldActivity = value;

}

If you look at the attached graphic, really all I want is the totalvalue displayed.not the month number or the totalhours. how do I get rid of these other two series? here is my code so far:

protected void CreateYearChart()

{

RadChartProjectActivityYearly.Legend.Clear();

RadChartProjectActivityYearly.Series.Clear();

FieldActivity _activity = FieldActivityService.GetByID(Int32.Parse(ddlFieldActivity.SelectedValue.ToString()));

RadChartProjectActivityYearly.ChartTitle.TextBlock.Text = _activity.Unit + " in " + ddlDetailYear.SelectedItem.Text;

List<FactProjectActivityTotalsByMonth> _factsBar1 = FactProjectActivityTotalsByMonthService.GetForYear(Int32.Parse(ddlDetailYear.SelectedItem.Text), Int32.Parse(ddlFieldActivity.SelectedValue.ToString()));

RadChartProjectActivityYearly.DataSource = _factsBar1;

RadChartProjectActivityYearly.Legend.Visible = true;

// RadChartProjectActivityYearly.Series[0].DataYColumn = "TotalValue";

RadChartProjectActivityYearly.PlotArea.XAxis.DataLabelsColumn = "ActivityMonthName";

RadChartProjectActivityYearly.DataBind();

RadChartProjectActivityYearly.AutoLayout = true;

foreach (Telerik.Charting.ChartSeries series in RadChartProjectActivityYearly.Series)

{

Debug.WriteLine(series.Name);

//if (series.Name != "TotalValue")

//{

// RadChartProjectActivityYearly.Series.Remove(series);

//}

}

//RadChartProjectActivityYearly.RemoveSeriesAt(2);

//RadChartProjectActivityYearly.RemoveSeriesAt(0);

I thought about creating the series manually but then I lose the X-axis labels so ideally I'd like to be able to databind to only one property of the object in the underlying list. Her is the declaration:

<telerik:RadChart ID="RadChartProjectActivityYearly" runat="server" skin="Forest" Width="1000px" >

<Legend>

<Appearance Position-AlignedPosition="TopRight"></Appearance>

</Legend>

<PlotArea>

<XAxis AutoScale="False" DataLabelsColumn="ActivityMonthName" ></XAxis>

</PlotArea>

</telerik:RadChart>

thanks for the help

Vista like File explore

HI Telerik,

I am looking for a file explorer for web application (web page) which should look like vista explorer or your FirstLook exploerer at http://demos.telerik.com/aspnet-ajax/fileexplorer/examples/default/defaultcs.aspx. Do you have any sample code to go ahead with this control? Can i add my own button in the menu? I would prefer vista explorer but i am ok with the example provided also. Could you please suggest me regarding this? I am using Rad file explorer for the first time and does not have much idea about its properties, how to bind etc.
Please do the needful ASAP.

Regards,
Srikanth
