[Solved] Resources Setting Selected Value

Hello,
After much research I still can't figure out how to set the selected value in a resource list. My Resources appear ok, and the correct value is added to the database, but on update, it always selects the 1st data value in the list no matter what the database value. It does not select the "-" unless my data field is null which is correct.

My appointment population loop below.

for (int i = 0; i < appCol.Count; i++)

{

Appointment apt = new Appointment();

apt.Owner = owner;

apt.ID = appCol[i].Id;

apt.Start = DateTime.SpecifyKind(Convert.ToDateTime(appCol[i].Start), DateTimeKind.Utc);

apt.End = DateTime.SpecifyKind(Convert.ToDateTime(appCol[i].End), DateTimeKind.Utc);

apt.RecurrenceRule = Convert.ToString(appCol[i].RecurrenceRule);

apt.Description = appCol[i].Description;

// load Apppointment Type Resources

apt.Resources.AddRange(GetResourcesByType(owner,"Appointment Types"));

if (appCol[i].RecurrenceParentId != null)

apt.RecurrenceParentID = appCol[i].RecurrenceParentId;

int reminderTime = 0;

if (Int32.TryParse(appCol[i].Reminder,out reminderTime))

{

Reminder r = new Reminder(reminderTime);

apt.Reminders.Add(r);

Tools.SetAppointmentsForApplication();

}

if (apt.RecurrenceParentID != null)

{

apt.RecurrenceState = RecurrenceState.Exception;

}

else if (apt.RecurrenceRule != string.Empty)

{

apt.RecurrenceState = RecurrenceState.Master;

}

apt.Subject += appCol[i].Subject;

appointments.Add(apt);

}

Problem plotting negative values on line chart

I am creating a line chart programmatically.

The chart has a datetime value for the xaxis and a numerical count for the yaxis.

If the yaxis values are +ve it all works fine but if there is a -ve value in the data, the chart does not plot and i get the error message 'There is no or empty series'

Here is the code used to create the chart:

int gridItem = (int)dataItem.GetDataKeyValue("PlayerCode");

RadChart1.Series.Clear();

RadChart1.Clear();

RadChart1.PlotArea.XAxis.Clear();

string scoreQuery =

"SELECT [ScoreDate], [ScoreValue] FROM [Scores] WHERE ([PlayerCode] = @PlayerCode) AND ([ScoreValue] > 0) ORDER BY [ScoreDate] ASC"

;

Connections scCon = new Connections(scoreQuery);

scCon.AddParam("PlayerCode", gridItem);

DataTable resTable = new DataTable();

resTable = scCon.ReturnTable();

ChartSeries chSeries = new ChartSeries();

chSeries.Type = ChartSeriesType.Line;

ChartAxisItem xAxis = new ChartAxisItem();

RadChart1.PlotArea.XAxis.IsZeroBased = false;

RadChart1.PlotArea.XAxis.AutoScale = false;

RadChart1.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortDate;

foreach (DataRow dr in resTable.Rows)

{

chSeries.AddItem(Convert.ToDouble(dr["ScoreValue"]));

DateTime scDate = new DateTime();

scDate = Convert.ToDateTime(dr["ScoreDate"]);

ChartAxisItem item = new ChartAxisItem();

item.Value = (decimal)scDate.ToOADate();

RadChart1.PlotArea.XAxis.AddItem(item);

}

RadChart1.PlotArea.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.Gradient;

RadChart1.PlotArea.Appearance.FillStyle.MainColor = Color.FromArgb(78, 198, 19);

RadChart1.PlotArea.Appearance.FillStyle.SecondColor = Color.FromArgb(123, 230, 108);

RadChart1.Series.Add(chSeries);

Any help is much appreciated.

GridCalculatedColumn with null datafields not displaying value

I'm doing some testing with the RadGrid CalculatedColumn. It's a timesheet application so I'd like to use the GridCalculatedColumn to total the hours for the week (row) and sum aggregate to total the hours for the day (column). Some days won't have hours so the datafield will pull in NULL. The sum aggregates are working fine but the GridCalculatedColumn is not displaying a value.

Here is the code for my columns:

    
            <rad:GridNumericColumn Aggregate="Sum" FooterAggregateFormatString="{0:F}" DataFormatString="{0:F}" DataField="Hours_Sun" DataType="System.Decimal" HeaderText="SUN" /> 
        
            <rad:GridNumericColumn Aggregate="Sum" FooterAggregateFormatString="{0:F}" DataFormatString="{0:F}" DataField="Hours_Mon" DataType="System.Decimal" HeaderText="MON" /> 
        
            <rad:GridNumericColumn Aggregate="Sum" FooterAggregateFormatString="{0:F}" DataFormatString="{0:F}" DataField="Hours_Tue" DataType="System.Decimal" HeaderText="TUE" /> 
        
            <rad:GridNumericColumn Aggregate="Sum" FooterAggregateFormatString="{0:F}" DataFormatString="{0:F}" DataField="Hours_Wed" DataType="System.Decimal" HeaderText="WED" /> 
        
            <rad:GridNumericColumn Aggregate="Sum" FooterAggregateFormatString="{0:F}" DataFormatString="{0:F}" DataField="Hours_Thu" DataType="System.Decimal" HeaderText="THU" /> 
        
            <rad:GridNumericColumn Aggregate="Sum" FooterAggregateFormatString="{0:F}" DataFormatString="{0:F}" DataField="Hours_Fri" DataType="System.Decimal" HeaderText="FRI" /> 
        
            <rad:GridNumericColumn Aggregate="Sum" FooterAggregateFormatString="{0:F}" DataFormatString="{0:F}" DataField="Hours_Sat" DataType="System.Decimal" HeaderText="SAT" /> 
        
            <rad:GridCalculatedColumn Aggregate="Sum" FooterAggregateFormatString="{0:F}" DataFormatString="{0:F}" DataFields="Hours_Sun, Hours_Mon, Hours_Tue, Hours_Wed, Hours_Thu, Hours_Fri, Hours_Sat" Expression="{0}+{1}+{2}+{3}+{4}+{5}+{6}" DataType="System.Decimal" HeaderText="WEEK TOTAL" />

In one row example, there are hours in only Monday and Tuesday. If I changed the DataFields to "Hours_Mon, Hours_Tue" and the Expression to "{0}+{1}" then the CalculatedColumn works correctly. Am I only allowed to do a calculation on 2 data fields or is it running into a problem with the null values for the rest of the days? Am I missing a property in my columns?

Best practise to make sure an event is fired

Dear fellows,

i just start with AJAX, because since the last weeks i was more involved in the RadControl for ASP.Net and Winforms.

i've noticed that most on my classic asp.net controls (in .ascx controls) don't fire the server side event code on first click, but on 2nd.

So what i am doing is, that i have one contentPlaceHolder in a master page and i drop my user controls on it.

I have added a ScriptManager to the master page.

Where to place AjaxManager and/or AJAX Panel to make sure that defined classic ASP.NET controls are behaving like before?

Specially my asp:Buttons are not working as expected and i need to execute server side code on first click.

So what is the best pratice for this.

2nd: in my apllication some buttons should appear only, if some steps was done before, means the user has to follow a defined way, and first when she/he has finished Step 2 - the BVutton for Step 3 becomes visible.

Because there is not databinding for buttons i currently use session variables for this taks. Any better way to do it ?

Thanks for helping.

Kind Regards

Default config and tools file

Hi,

I was unable to find default config and tools file for latest rad editor. In previous versions, it was always present in RadControls folder and we need some default files to start configuration with. I made some search but with no avail.

Moreover, in documentation is mention about "ConfigFile" property but lately downloaded RadEditor does not expose such property - what's wrong?

Thanks for help.

remove Ajax Loading panel after page load

Hello, guys.
In my application I added loading panel on client PageLoad event as it was described on this forum.
            function pageLoad(sender, eventArgs) {
                if (!eventArgs.get_isPartialLoad()) {
                    $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("PAGE_LOAD");
                }
            }
But after I added some ajax requests to my code I found that the panel used as updated control gets redrawn each time (to be exact not, each but starting from second time and I think thi is a kind of bug) I perform ajax request.
I tryed to remove the ajax setting made to AjaxManager in a design time using the following code
        bool Stop = false;
        foreach (AjaxSetting Setting in RadAjaxManager1.AjaxSettings)
        {
            if (Setting.AjaxControlID == RadAjaxManager1.ID)
                foreach (AjaxUpdatedControl Ctrl in Setting.UpdatedControls)
                    if (Ctrl.ControlID == pnlSplash.ID)
                    {
                        Setting.UpdatedControls.Remove(Ctrl);
                        Stop = true;
                        break;
                    }
            if (Stop)
                break;
        }

but it didn't help. It still appears during ajax requests made from client code.
What have I done wrong?

With respect, Sergey.

RadGrid with AllowAutomaticUpdates from a DataTable in runtime

Hi all,

I have a CSV file that is selected and read using the RadUpload control. I read each line and populate a DataTable on a C# ASP.NET webpage. Once that is done, I used a RadGrid to populate those values into the grid with AutoGenerateColumns="True"

The rows that don't comply are highlighted in red on RadGrid1_ItemDataBound event, so that user know that they need to be changed.

Now I want the user to go and edit each invalid row and update the changes. Currently with AllowAutomaticUpdates="True" is it not letting me save anything, it just displays the same information when Update is clicked. I am not using an SQL Data Souce so the first question is whether AllowAutomaticUpdates does actually work with just a DataTable or not? If not any suggestion on how I can make the row update-able with minimum coding.

Many thanks

Mark up code is below:

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"> </telerik:RadScriptManager>

<telerik:RadFormDecorator ID="RadFormDecorator1" Runat="server" Skin="Forest" DecoratedControls="All" />

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />

RowHeight not applied across the whole row?

Hello,

I have the following mark-up/code for the RadScheduler. (See Attached SchedulerMarkup.gif).
But the RadScheduler seems to only resize the Time row, but not across all the columns. (See Attached RadSchedular.jpg).

Am I doing something wrong or is there any other property I need to set?

And, I believe, because of this, the display seems to be off. The time line blocks should be from 9 AM ~ 6 PM on Monday, then 9 AM ~ 5 PM from Tuesday to Friday.

My telerik control version is :2009.02.0920.35.

Thanks,
Annie
