Hierarchal Grid Sum Aggregate "neither a DataColumn nor a DataRelation" Problem
Hello all, i'm having an issue attempting to Sum a nested grid column using Aggregate="Sum" with hiearchy ONLY when a user deletes a row from the nested grid (any Rebind() commands result in error listed below). If I remove the Aggregate="Sum" parameter from the nested grid, all ajax functionality works perfectly (rows removed upon delete, database values update from edit, etc.). But if the Aggregate parameter is used, I keep getting the following error:

[ColumnName] is neither a DataColumn nor a DataRelation for table.

The grid also utilizes RadAjax with an AjaxSetting to update itself. I'm experienced with the RadGrid, having deployed it various times before, but this one is stumping me and holding up the release of the project. Any help would be greatly appreciated.

Here's the code used:

<UX:RadGrid ID="uxExpenseGrid" ShowStatusBar="true" AutoGenerateColumns="false" AllowSorting="false" GridLines="None" OnItemCommand="GridItemCommand" OnNeedDataSource="InitEmployeeExpenses" OnDetailTableDataBind="EmployeeExpensesDataBind" EnableEmbeddedSkins="false" Skin="BMT" OnPreRender="InitPreRender" runat="server">  
                <MasterTableView Name="rootExpenses" HierarchyLoadMode="ServerBind" NoMasterRecordsText="&nbsp;&nbsp;No employee expenses recorded.">  
                    <DetailTables>

            } 

Again, any help being able to Sum a nested grid column would be awesome. This is something that is preventing the project from going live. Thank you.

Position of ManualClose [x]
Ok, this is making me feel like a big dummy, because after searching apparently nobody else has ever had this problem.  When I try to use HideEvent="ManualClose" with my tooltips, the [x] for closing the tooltip appears on top of the tooltip text, hiding some of the text. What simple thing am I missing here?  If it matters, I am using the Office2007 skin and not specifying a fixed height, since the length of text can vary.

Accessing filtered rows
Hi,

Suppose I have 20 records in my grid. I apply a filter/sort. I get 10 records. Is there a way to access "only" these 10 records out of the complete dataset?

Context: While editing, my user wants to update a field in only one record, click on a checkbox to say "Apply to all filtered records" and wants the changes to be applied to the filtered dataset.

RadScriptManager, MasterPages - PageMethods is Undefined
Hello,

I'm trying to implement an extra toolbar button in my RadEditor that will call my codebehind via a Page Method and submit some content.  We're using Master Pages and I have my RadScriptManager on the master page:

<telerik:RadScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" />

for my RadEditor in my ASCX user control I have:
<telerik:EditorTool Name="SaveDesign" Text="SAVE" ShowText="true" ShowIcon="false" />

and further down:

<script type="text/javascript"> 
Telerik.Web.UI.Editor.CommandList["SaveDesign"] = function(commandName, editor, args) 
{ 
   PageMethods.MySave("input string",CallSuccess,CallFail); 
}; 
 
function CallSuccess(results, userContext, methodName) 
{ 
 alert(results); 
} 
function CallFail(errors, userContext, methodName) 
{ 
 alert(errors.get_Message()); 
} 
</script> 
 

and in my codebehind I have:

[System.Web.Services.WebMethod()] 
        public static string SaveShit(string stuff) 
        { 
            return "did something"; 
        } 


When I browse the page and click the toolbar button I get the error:

Error: 'PageMethods' is undefined

I'm kind of stuck with this, any help would be appreciated.

Css problem
Hi, i have my own skin for my slider, (vertical slider)

with :

 
.RadSlider_simbaSkin .rslItemsWrapper .rslItemSelected  
{   /*background: url('Slider/DragVerticalHandle.png') no-repeat;*/ 
    background: url('Slider/DragVerticalHandle.png') no-repeat; 
    /*border:1px solid green;*/ 
    color: #999900; 
} 

Everything is working fine, except when my first element is selected, where there is no background image;

I've searched why, and with FireBug i found this :

.Radslider .rslVertical .rslItemsWrapper .rslItemFirst, .RadSlider .rslHorizontal .rslItemsWrapper .rslItemFirst { 
background-image:none; 
} 

And its removing my background image when my first element is selected.

And it's not in my code or in my css file, its in a "WebResource.axd?d=YR8ix.............................................&t=6338....0316" file.


How can i find this line and delete it ?

Series names for Legend Gantt Chart
void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)  
    {  
        DataRowView drv = e.DataItem as DataRowView;  
        DateTime startDate = (DateTime)drv["EventDate"];  
        DateTime endDate = (DateTime)drv["EndDate"];  
        StringBuilder sb = new StringBuilder();  
        sb.Append(drv["Title"].ToString());  
        sb.AppendFormat("\n{0} - {1}", startDate.ToShortDateString(), endDate.ToShortDateString());  
        e.SeriesItem.Name = drv["Source"].ToString();  
        e.SeriesItem.ActiveRegion.Tooltip = sb.ToString();  
          
    } 
I'm struggling getting the series names to show up properly in the legend. All I get is 'Series xx' and I'm sure I'm overlooking something very simple, or at least I hope so.

Basic theory: I'm grabbing list items from various SharePoint lists via Lists Web service, converting the XmlNodes into DataSets, doing a little manipulation to the data, then create a DataTable with all List items.
DataTable schema looks like:
dt.Columns.Add("Source", typeof(String));  
dt.Columns.Add("Title", typeof(string));  
dt.Columns.Add("From", typeof(double));  
dt.Columns.Add("To", typeof(double));  
dt.Columns.Add("EventDate", typeof(DateTime));  
dt.Columns.Add("EndDate", typeof(DateTime)); 

For each Source, I want it to show up in different colors for the Gantt chart and display the name so the user knows which list it came from.

Snippet for chart:
ChartSeries series = new ChartSeries();  
RadChart1.PlotArea.YAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortDate;  
                  
        RadChart1.PlotArea.YAxis.Appearance.LabelAppearance.RotationAngle = 45;  
        RadChart1.PlotArea.YAxis.LabelStep = 1;  
        RadChart1.PlotArea.YAxis.Appearance.LabelAppearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Top;  
        RadChart1.Series.Clear();  
        RadChart1.PlotArea.YAxis.AutoScale = false;  
        RadChart1.PlotArea.YAxis.AxisMode = ChartYAxisMode.Extended;  
 
        DataTable dt = getListItems();  
 
        RadChart1.PlotArea.YAxis.AddRange(from.ToOADate(), to.ToOADate(), step);  
        RadChart1.DataSource = dt;  
 
        series.Type = ChartSeriesType.Gantt;  
        series.Appearance.LabelAppearance.Visible = false;  
        series.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.SeriesName;  
        series.Appearance.BarWidthPercent = 30M;  
        series.DataYColumn = "From";  
        series.DataYColumn2 = "To";  
        RadChart1.Series.Add(series);  
        RadChart1.SeriesOrientation = ChartSeriesOrientation.Horizontal;  
        RadChart1.ChartTitle.TextBlock.Text = "Aggregated Calendar";  
        if(_realWidth > 0)  
            RadChart1.Width = new Unit(_realWidth * .97);  
RadChart1.DataBind(); 

Here is the ItemDataBound event:
void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)     
    {     
        DataRowView drv = e.DataItem as DataRowView;     
        DateTime startDate = (DateTime)drv["EventDate"];     
        DateTime endDate = (DateTime)drv["EndDate"];     
        StringBuilder sb = new StringBuilder();     
        sb.Append(drv["Title"].ToString());     
        sb.AppendFormat("\n{0} - {1}", startDate.ToShortDateString(), endDate.ToShortDateString());     
        e.SeriesItem.Name = drv["Source"].ToString();     
        e.SeriesItem.ActiveRegion.Tooltip = sb.ToString();     
             
    }    
 

I would expect to be able to set the column that is being used for the Series like
series.DataSeriesColumn = "Source"; //DataTable column name 
similar to how you specify the DataYColumn, DataYColumn2, etc.

Surely, I don't have to create new ChartSeries objects for every list I aggregate? Any help would be appreciated.

GridExpandColumn or GridEditCommandColumn
How can I make a GridEditCommandColumn work as a GridExpandColumn?
<telerik:GridEditCommandColumn ButtonType="ImageButton" EditImageUrl="../Grafikk/RadGrid/SinglePlus.gif" EditText="Edit" CancelImageUrl="../Grafikk/RadGrid/SingleMinus.gif" CancelText="Cancel" ItemStyle-HorizontalAlign="Center" /> 

First I want the PLUS gif to become a MINUS gif when clicked and my EditFormTemplate opens, and when I click on MINUS, a cancel command is fired.

[Solved] DatakeyValue not updated with new search results
Hi,

I have a small search page that dumps it's results to a RadGrid. My search routine looks like this:
 var searchResults = db.AbsenceSearch(txtIndividualSearchBox.Text.ToUpper(),  
                ddlEnterprises.SelectedValue == "-1" || ddlEnterprises.SelectedValue == "" ? null : (int?)Convert.ToInt32(ddlEnterprises.SelectedValue), ddlDivisions.SelectedValue == "-1" || ddlDivisions.SelectedValue == "" ? null : (int?)Convert.ToInt32(ddlDivisions.SelectedValue),  
                dateFrom,  
                dateTo,  
                reevaluationPeriod,  
                cbIsOpen.Checked,  
                userid).ToList();  
 
            RadGrid1.DataSource = searchResults; 

My initial databind seems to have correct DataKeys values in the grid, but when I do another search with new search field values, my new data appears OK, but the old Datakeys are still there. I for example found out that on initial pageload I have a DataKey value of 2000 in the 3rd item row in the grid, and when I do an new search, and the grid loads with the new data, I still have DataKey value 2000 in the 3rd item row.

This is how I am retrieving the Datakeys:
protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)  
        {  
 
            if (e.Item.ItemType == Telerik.Web.UI.GridItemType.Item || e.Item.ItemType == Telerik.Web.UI.GridItemType.AlternatingItem)  
            {  
                int eID = (int)e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["id"];  
                Response.Redirect(<to some page>);  
            }  
        } 

I am sure this is a simple beginner mistake. Please help.

SelectedItem in detailtables and nestedviewtemplate
Hi,

I have a radgrid set up with detailtables and nestedviewtemplate.

The markup (without all the details...) looks like this :
<telerik:radgrid ...> 
  <DetailTables> 
    <telerik:GridTableView ...> 
      <DetailTables> 
        <telerik:GridTableView ...> 
          <NestedViewTemplate> 
            <telerik:RadTabStrip ...> 
            </telerik:RadTabStrip> 
            <telerik:RadMultiPage ...> 
              <telerik:RadPageView ...> 
                <telerik:RadGrid ...> 
                  <DetailTables> 
                    <telerik:GridTableView ...> 
                      <DetailTables> 
                        <telerik:GridTableView ...> 
                        </telerik:GridTableView> 
                      </DetailTables> 
                    </telerik:GridTableView> 
                  </DetailTables> 
                </telerik:RadGrid> 
              </telerik:RadPageView> 
            </telerik:RadMultiPage> 
          <NestedViewTemplate> 
        </telerik:GridTableView   
      </DetailTables> 
    </telerik:GridTableView   
  </DetailTables> 
</telerik:radgrid> 

I would like to have all parent rows, of the row the user left or right-clicks,selected.
In my code-behind i have code in the ItemCommmand event that when a user expands a row e.Item.Selected is set to true.
So that row is selected, but i also would like the parent rows to be selected and all other rows deselected.

We have the Office2007 skin (very nice one by the way!!) and selected rows are displayed in orange. The reason we want the parent rows selected as well is to make it easer for the user to see where he "is" in the hierarchial grid.

Does anybody know what i need to do to make this work? I think i have to set each grid (the grids in the NestedViewTemplate as well) to multiselect. And then catch the left or right mouseclick, loop through each parent control and clear all selected items if the parent is a grid and if it is a griditem the set selected to true?
