RadComboBox dropdown not displaying in ReportViewer

Hello,

I have run into an issue where a RadComboBox does not display any items when clicked in a WPF 4 application (Reporting Version 5.3.11.1116). The combobox itself lies within a RadToolBar in a ReportViewer. A small sliver of a dropdown is displayed (see image, same width as the RadComboBox) as though there is nothing in it. Even if there were no items to display, I would expect the combobox's dropdown to respect the MinWidth="150" seen below.

<telerik:RadToolBar Grid.Row="0">

I have included the following in a configSection in my app.config to no avail:

<Telerik.Reporting>

<Extensions>

<Render>

<Extension name="IMAGE" description="TIFF Image" visible="false" />

<Extension name="PDF" description="Adobe Acrobat PDF" visible="true" />

<Extension name="MHTML" description="Compressed Web Archive" visible="false" />

<Extension name="XLS" description="Excel" visible="false" />

<Extension name="CSV" description="Comma Seperated Values" visible="false" />

<Extension name="RTF" description="Rich Text File (RTF)" visible="false" />

<Extension name="XPS" description="Microsoft XPS Document" visible="true" />

</Render>

</Extensions>

</Telerik.Reporting>

Is there anything apparent that I am missing?

Thanks for your time,

Dane

PictureBox BitmapImage/Embedded resource problems

In a report I'm working on we want to display some images based on the value of a field. For that purpose I've created a UserFunction that grabs the image out of our embedded resource pack and returns it.

This is where things get a bit ugly.

Since this is a WPF app, we use BitmapImage for storing embedded image resources. It appears that the PictureBox doesn't support BitmapImage? The exception rendered in the Picturebox is "The given key was not present in the dictionary"

To avoid using BitmapImage I've tried returning the URI to the resource, also to no avail. The URI is prefixed with pack:// and that is apparently an unsupported prefix (according to the exception message.)

Going from BitmapImage to an actual GDI+ Image is not trivial since we're running a WPF app and I would really like to avoid doing that. Physical paths are also not an option...

Any ideas?

Reportbook in Q2

Hi ... after update to 2012/Q2 i cannot figure out, how to convert my code to your new reportsource system:

protected void BTN_Process_Click(object sender, EventArgs e)

{

ReportBook reportbook = new ReportBook();

ReportViewer1.Report = null;

foreach (GridDataItem si in RG_Reports.SelectedItems)

{

string ReportName = si.OwnerTableView.DataKeyValues[si.ItemIndex]["Report"].ToString();

Type reportType = Type.GetType(Server.UrlDecode(ReportName));

Telerik.Reporting.Report report = (Telerik.Reporting.Report)Activator.CreateInstance(reportType);

report.ReportParameters["Filter"].Value = Session["FilterTextAsset"];

report.ReportParameters["FilterExA"].Value = Session["FilterExA"];

report.ReportParameters["IsActive"].Value = Session["FilterIsCheckedAsset"];

report.ReportParameters["OrgUnitId"].Value = Request.QueryString["OrgUnitId"];

report.ReportParameters["AssetId"].Value = Request.QueryString["AssetId"];

report.ReportParameters["UserId"].Value = Session["UserId"];

report.ReportParameters["IsInStock"].Value = Session["FilterIsInStockAsset"];

report.ReportParameters["IsOrder"].Value = Session["FilterIsOrder"];

report.ReportParameters["Group1"].Value = new string[] { "" };

report.ReportParameters["Group2"].Value = new string[] { "" };

report.ReportParameters["Sort1"].Value = "";

report.ReportParameters["Sort2"].Value = "";

reportbook.Reports.Add(report);

}

if (RG_Reports.SelectedItems.Count != 0)

{

reportbook.DocumentName = "Assets";

ReportViewer1.Report = reportbook;

}

this code doesn't work anymore!

Thank you!

Urgent: How do I add goup footer for total in a table.

Telerik Reporting:
I have urgent requirement to make a automated reporting system and I am trying to create a report programmatically using telerik.
So, far I was able to create group but not able to add group footer so that I can show sum, avg etc.
My code is:

Telerik.Reporting.TextBox txtGroupHeader = new Telerik.Reporting.TextBox();

Telerik.Reporting.TextBox txtGroupTotal;// = new Telerik.Reporting.TextBox();

toggleVisibilityAction1 = new Telerik.Reporting.ToggleVisibilityAction();

txtGroupHeader.Action = toggleVisibilityAction1;

toggleVisibilityAction1.DisplayExpandedMark = false;

// Required for telerik Reporting designer support

InitializeComponent();

TableGroup group = new TableGroup();

Telerik.Reporting.TableGroup tableGroup4 = new Telerik.Reporting.TableGroup();

Telerik.Reporting.TableGroup tableGroup5 = new Telerik.Reporting.TableGroup();

group.Name = "Season";

group.Groupings.AddRange(new Telerik.Reporting.Grouping[] {

new Telerik.Reporting.Grouping("=Fields.Season")});

group.Sortings.AddRange(new Telerik.Reporting.Sorting[] {

new Telerik.Reporting.Sorting("=Fields.Season", Telerik.Reporting.SortDirection.Asc)});

txtGroupHeader.Name = "txtGroupHeader";

txtGroupHeader.Size = new Telerik.Reporting.Drawing.SizeU(Telerik.Reporting.Drawing.Unit.Cm(3.9314577579498291D), Telerik.Reporting.Drawing.Unit.Cm(0.43585944175720215D));<

br>

txtGroupHeader.Style.BackgroundColor = System.Drawing.Color.Red;

txtGroupHeader.Style.BorderStyle.Bottom = Telerik.Reporting.Drawing.BorderType.Solid;

txtGroupHeader.Style.Color = System.Drawing.Color.White;

txtGroupHeader.Style.Font.Bold = true;

txtGroupHeader.StyleName = "";

txtGroupHeader.Value = "=Fields.Season";

tableGroup4.Groupings.AddRange(new Telerik.Reporting.Grouping[] {

new Telerik.Reporting.Grouping(null)});

group.Sortings.AddRange(new Telerik.Reporting.Sorting[] {

new Telerik.Reporting.Sorting("=Fields.Season", Telerik.Reporting.SortDirection.Asc)});

tableGroup4.Name = "Details";

tableGroup5.Name = "Group1s";

//group.ChildGroups.Add(tableGroup4);

//group.ChildGroups.Add(tableGroup5);

//this.table1.Body.Rows.Add(new Telerik.Reporting.TableBodyRow(Telerik.Reporting.Drawing.Unit.Cm(1)));<br>

this.table1.Corner.SetCellContent(0, 0, txtGroupHeader);

this.table1.Items.Add(txtGroupHeader);

group.ReportItem = txtGroupHeader;

//Remove the detail group

TableGroup detailGroup = table1.RowGroups[0];

table1.RowGroups.Clear();

//detailGroup.Visible = false;

toggleVisibilityAction1.Targets.AddRange(new Telerik.Reporting.IToggleVisibilityTarget[] {

detailGroup});

//Add the detail group as a child to the AgeGroup (nest it)

group.ChildGroups.Add(detailGroup);

table1.RowGroups.Add(group)

;
---------------------

I tried finding help with visual studio generated code but to no avail. Please help as it is urgent.

Chart Docking and Anchor without stretching the chart

I have a report that has a Table on the left and a Chart on the right.

The Table can grow to any size, which makes the report grow.

So I have tried Anchoring or Docking the Chart to the top and bottom of the report so that it grows as well.

It does grow, but the chart is stretched. It doesn't re-render/re-layout to the new size.

How can I get it to do this?

Using Telerik Reporting 2011 Q3.

Thanks.
