Error loading Report Viewer Control

Hi,

I'm having a problem when loading the report viewer control in to a Web Form, a drag the control and nothing happens, if a try to insert the code directly in the form an error of a TAG PREFIX appears, what it can be wrong or what a need to configure to solve this issue, i already add the following references:

* Telerik.reporting
* Telerik.ReportViwer.WebForms
* Telerik.ReportViwer.WinForms

I posted a similar issue about 2 weeks ago and it simply disappear, it think maybe i need to post this under another topic?, but a didn't get any email, i don't know what happens with the other thread i posted.

Anyone can help me, thanks in advance.

[Solved] Adjusting Column Width with Reflection

I'm attempting to adjust the column width programatically and from other forum posts I've read that there is allot involved.

I can Hide Column content on ItemDataBound, but I cannot collapse the width.
Using JustCompile and the debugger I believe I'm setting all the proper widths, but I cannot get it to collapse.

below is my code.
Can you provide any insight on the events between ItemDataBound and rendering and if there is an event between where I can adjust these values.

public static void RemoveColumns(this Telerik.Reporting.Table tableDef, params int[] columns)

{

/*

var colGroups = Flatten(tableDef.ColumnGroups).ToList();

foreach (int column in columns)

{

// colGroups[column].Visible = false; // Object not found Error in binding

colGroups[column].Filters.Clear();

colGroups[column].Filters.Add(new Telerik.Reporting.Filter("=1", Telerik.Reporting.FilterOperator.Equal, "=0")); // Object not found Error in binding

}

return;

*/

var tableBody = tableDef.Body;

var tableCells = tableBody.Where(x => x.ReportItem != null).ToList();

var zero = Telerik.Reporting.Drawing.Unit.Inch(0);

foreach (int colIndex in columns.OrderByDescending(x => x))

{

tableBody.Columns[colIndex].Width = zero;

// shrink all cell.reportItem(s)

foreach (var cell in tableCells.Where(x => x.ColumnIndex == colIndex))

{

// cell.ReportItem.Visible = false; throws error during Binding

cell.ReportItem.Width = zero;

if (cell.ReportItem is Telerik.Reporting.TextItemBase)

((Telerik.Reporting.TextItemBase)cell.ReportItem).CanGrow = false;

}

/// <summary>

/// ItemDataBound, Remove columns by settings its content Visibility

/// </summary>

/// <param name="table"></param>

/// <param name="columns"></param>

public static void RemoveColumns(this Telerik.Reporting.Processing.Table table, params int[] columns)

{

RemoveColumns((Telerik.Reporting.Table)table.ItemDefinition, columns);

var zero = Telerik.Reporting.Drawing.Unit.Inch(0);

foreach (var textbox in table.TableCells(x => columns.Contains(x.ColumnIndex)).OfType<Telerik.Reporting.Processing.TextBox>())

{

// textbox.Visible = false; // Doesn't collapse column

textbox.Width = zero;

textbox.Value = string.Empty;

TextboxCanGrowProperty.SetValue(textbox, false, null);

}

foreach (var column in table.Columns.Where(x => columns.Contains(x.Index)))

{

TableColumnWidthProperty.SetValue(column, 0D, null);

}

private static IEnumerable<Telerik.Reporting.Processing.ITableCell> TableCells(this Telerik.Reporting.Processing.Table table, Func<Telerik.Reporting.Processing.ITableCell, bool> predicate = null)

{

Telerik.Reporting.Processing.ITableCell cell;

int colCount = table.Columns.Count;

int rowCount = table.Rows.Count;

for (int rowIndex = 0; rowIndex < rowCount; rowIndex++)

{

for (int colIndex = 0; colIndex < colCount; colIndex = colIndex + cell.ColumnSpan)

{

cell = table.GetCell(rowIndex, colIndex);

if (predicate == null || predicate(cell))

yield return cell;

}

public static IEnumerable<Telerik.Reporting.TableGroup> Flatten(this IEnumerable<Telerik.Reporting.TableGroup> collection)

{

foreach (var group in collection)

{

yield return group;

foreach (var subGroup in Flatten(group.ChildGroups))

yield return subGroup;

}

private static PropertyInfo _tablecolumnWidthProperty = null;

public static PropertyInfo TableColumnWidthProperty

{

get

{

if (_tablecolumnWidthProperty == null)

_tablecolumnWidthProperty = typeof(Telerik.Reporting.Processing.TableColumn).GetProperty("Width", BindingFlags.Instance | BindingFlags.NonPublic);

return _tablecolumnWidthProperty;

}

private static PropertyInfo _textboxCanGrowProperty = null;

public static PropertyInfo TextboxCanGrowProperty

{

get

{

if (_textboxCanGrowProperty == null)

_textboxCanGrowProperty = typeof(Telerik.Reporting.Processing.TextItemBase).GetProperty("CanGrow", BindingFlags.Instance | BindingFlags.NonPublic);

return _textboxCanGrowProperty;

}

Thanks
Steve

CrossTab Report - Conditional Formatting and nulls

I have a crosstab report which shows stats for permits submitted over a 6 year period. I have them broken down by several different parameters. I have the latest year column set to be shaded a dark grey and the 2nd, 4th, and 6th years shaded a light grey. I sort them into the years based on a date permit was approved. My problem is that if here is no permits that match one of the categories it doesn't shade that box. It doesn't make the report look good with breaks in the shading. I have it filling 0's for the null cells by checking for nulls but it still doesn't shade the cells.

Any help would be greatly appreciated.

Excel Native Headers Export

Hello,

We are running on an older version of the Reporting 2011 Q2 but need to user the native header features.

I have set the device information header variables (they work fine for grid lines) to true for UseNativePageHeader but the report is rendered with the header at the top of the page basically ignoring the variable.

Is there anything I am missing?

Evaluating Telerik Reporting

RE: http://www.telerik.com/products/reporting/data-presentation-and-analysis.aspx

We are internally evaluating Telerik Reporting. Looks like to use/show charts (bar, graph, pie, etc.) we would need to also buy RAD controls. Is that a right assessment?

Infinite Loop in PageHeaderSection

My report is not bound to a DataSource, but in the PageHeaderSection my Textbox_ItemDataBinding event keeps getting called in an infinite loop.

I have a pretty complex table in a ReportHeaderSection that is bound, but stepping through the debugger the Table finishes binding its dataset without any issues. I originally had it in the detailSection but changed it in my debugging efforts.

How can I determine what is causing the infinite loop in the PageHeaderSection when the processing is done in the ReportEngine.

Steve
