Radeditor export to PDF with images throws error

Hi guy's

I'm using Radeditor on a ASP.Net webpage using VB.NET
On the page I use an radeditor with enabled = false just to show HTML content and use some features of the editor.

The content below is sample content and when I try to export to PDF it gives me an error.
When I remove the image all works fine.

I used the sample database content provider and everything worked fine except the export to PDF with images having that database path still in the source string.

So I made my program that the images are stored in the db manually and just before loading the content I load the images from the db manually so that the images in the content can use local (virtual) references.

Does anybody see what's wrong with the image in my sample content and especially the image waterlelies.jpg ??

The error comes after i clicked "open" in the pdf dialog and it say's that de pdf cannot be opened because the filetype is not supported by acrobat reader. If I save the pdf it's size is 0kb ...

Where can I see more detaild error subscription?

Regards,

Rick Rehorst

Selected Value Resets-radcombobox

I have a repeater control in which I hava 2 labels and a radcombo box. I am able to populate the labels and the radcombobox.

The way it should work is I need to map a label text to the value in the radcombo box . The problem is even though the value in the combo is selected it keeps reseting to the first item in the drop down list.
Can someone help me to keep the selected value of the radcombo box selected.See attached jpg.

Select Button not visible

Hi,

I have a radupload control. When I deploy the site to the server the select button does not render and I only see a cropped text input. I can click on that and select a file but it's not intuitive for the user.

I've gone through the forum threads and tried several things but none of them seemed to work. I've also tried the suggestions under http://www.telerik.com/help/aspnet-ajax/upload-select-button-not-visible-in-ie.html.

It renders fine when I run it through my visual studio but the sleect is not visible when deployed on the server.

Please help.

RadDock padding

Hello, Telerik Team.

In the attached file, you will find a screen shot of the same web application in different browsers. On the left, Firefox 3.6.12; on the right, IE 8.0.

In Firefox, a vertical scroll bar is displayed because the RadDock component is not large enough to display all controls.
In IE, the vertical bar is not displayed.
It appears that padding in IE is "smaller" than in Firefox.

Is there any change I should implement in the following code in order to have a similar lay out in both browsers?

<asp:Panel runat="server" ID="DockPanel">

<telerik:RadDock

Image Editor File Type and Compression

It appears the image editor is saving images as .png files. Is there a way to save it as other file types (.jpg, .gif, etc). Also when saving as .jpg is it possible to set the compression/optimization?

RadWindow and IE9 Compatibility Issue

I upgraded to Q3 2011 and in the processing of porting my applications over from an older version (2007).

The problem is the following - when I restore a RadWindow, the contents of the window goes back its initial configuration.

Ive done this simple test - a aspx page with just just one control - a test box. I call it into a RadWindow - the text box is blank. I enter some text, minimise it and the restore it. The test box is blank. It appears to do a call back even thought ive added the line 'If Page.IsPostBack = True then Exit Sub' in the Page_Load event. The Text box is in an UpdatePanel .

The text is retained if I run it in IE8 (or in IE9 using the 2007 controls)

Inheriting from RadTreeView

Are there any examples out there on how to inherit from RadTreeView? I want override both the server side component AND the client side AJAX component.

I can easily override the server side component, but the problem being that both RadTreeView & MyTreeView has their own AJAX component and I am running into problems when radTreeView fires onCollapsed, the variables initialized in MyTreeView AJAX component are null.

So I really would like to have myTreeView AJAX component inherit from the RadTreeView AJAX component. After inheriting from RadTreeVIew is there a way to turn off the AJAX component and just use the inherited one from MyTreeView?

Problem filtering DateTimeColumn

Hi,
I have a serious problem filtering a GridDateTimeColumn in a dynamically created grid. I tried to correct it following this article:
http://www.telerik.com/help/aspnet/grid/grdfilteringfordatetimecolumnwithdataformatstring.html
but with no result. I use german culture and maybe that is the cause for the problem.

Is there any known issue with that?

Here is the code for creating the grid:

private void createGrid()

{

RadGrid grid = new RadGrid();

this.rgWorkflows = grid;

setGridProperties(grid);

}

private void setGridProperties(RadGrid grid)

{

grid.ID = "rgWorkflows";

grid.EnableViewState = true;

grid.AutoGenerateColumns = false;

grid.AllowSorting = true;

grid.AllowPaging = true;

grid.AllowFilteringByColumn = false;

grid.GridLines = GridLines.None;

grid.Width = Unit.Percentage(99.8);

grid.Height = Unit.Percentage(99.8);

grid.HeaderStyle.Width = Unit.Pixel(150);

grid.AllowMultiRowSelection = true;

grid.MasterTableView.PagerStyle.Mode = GridPagerMode.NextPrevNumericAndAdvanced;

grid.ClientSettings.EnableRowHoverStyle = true;

grid.ClientSettings.Selecting.AllowRowSelect = true;

grid.ClientSettings.Scrolling.AllowScroll = true;

grid.ClientSettings.Scrolling.UseStaticHeaders = true;

grid.ClientSettings.Scrolling.SaveScrollPosition = true;

grid.ClientSettings.Resizing.AllowColumnResize = true;

grid.ClientSettings.Resizing.ClipCellContentOnResize = false;

grid.ClientSettings.Resizing.EnableRealTimeResize = true;

grid.ClientSettings.Resizing.ResizeGridOnColumnResize = true;

grid.MasterTableView.DataKeyNames = new string[] { "Id" };

grid.MasterTableView.OverrideDataSourceControlSorting = true;

grid.PagerStyle.AlwaysVisible = true;

if (!IsPostBack)

{

grid.MasterTableView.PageSize = 15;

}

grid.GroupingSettings.CaseSensitive = false;

grid.MasterTableView.PagerStyle.Width = 1000;

grid.MasterTableView.OverrideDataSourceControlSorting = true;

grid.MasterTableView.EnableColumnsViewState = false;

grid.AllowFilteringByColumn = true;

grid.AllowMultiRowSelection = false;

}

The grid's column are dynamically created like this one:

public static void AddDateTimeFieldToGridView(string fieldName, string headerText, RadGrid grid, int? width)

{

GridDateTimeColumn dtc = new GridDateTimeColumn()

{

HeaderText = headerText,

DataField = fieldName

};

dtc.SortExpression = fieldName.Trim();

dtc.AllowSorting = true;

dtc.Resizable = true;

dtc.UniqueName = fieldName;

dtc.DataFormatString = "{0:dd.MM.yyyy}";

dtc.PickerType = GridDateTimeColumnPickerType.DateTimePicker;

dtc.UniqueName = fieldName;

if (width != null)

{

dtc.HeaderStyle.Width = width.Value;

}

grid.Columns.Add(dtc);

}

And the code for the correction I have tried is this (which is executed in ItemCommand event):

private static void setDateFilterPattern(GridCommandEventArgs e, RadGrid grid, string fieldName, string columnUniqueName)

{

if (e.CommandName == RadGrid.FilterCommandName

&& ((Pair)e.CommandArgument).Second.ToString() == columnUniqueName

&& ((Pair)e.CommandArgument).First.ToString() != "NoFilter"

&& grid != null)

{

e.Canceled = true;

GridFilteringItem filterItem = (GridFilteringItem)e.Item;

string currentPattern = (filterItem[((Pair)e.CommandArgument).Second.ToString()].Controls[0] as RadDatePicker).SelectedDate.Value.ToShortDateString();

string filterPattern = "";

string filterOption = (e.CommandArgument as Pair).First.ToString();

GridBoundColumn dateColumn = (GridBoundColumn)e.Item.OwnerTableView.GetColumnSafe(columnUniqueName);

filterPattern = currentPattern;

switch (filterOption)

{

case "EqualTo":

var dateTime = Convert.ToDateTime(filterPattern);

filterPattern = String.Format("[" + fieldName + "] > '{0}' AND [" + fieldName + "] < '{1}'", filterPattern,

dateTime.AddDays(1).ToShortDateString());

dateColumn.CurrentFilterFunction = GridKnownFunction.EqualTo;

break;

case "NotEqualTo":

var dateTime1 = Convert.ToDateTime(filterPattern);

filterPattern = String.Format("[" + fieldName + "] < '{0}' OR [" + fieldName + "] > '{1}'", filterPattern,

dateTime1.AddDays(1).ToShortDateString());

dateColumn.CurrentFilterFunction = GridKnownFunction.NotEqualTo;

break;

case "GreaterThan":

filterPattern = "[" + fieldName + "] > '" + filterPattern + "'";

dateColumn.CurrentFilterFunction = GridKnownFunction.GreaterThan;

break;

case "LessThan":

filterPattern = "[" + fieldName + "] < '" + filterPattern + "'";

dateColumn.CurrentFilterFunction = GridKnownFunction.LessThan;

break;

case "GreaterThanOrEqualTo":

var dateTime2 = Convert.ToDateTime(filterPattern);

filterPattern = String.Format("[" + fieldName + "] > '{0}' AND [" + fieldName + "] < '{1}' OR [" + fieldName + "] >= '{0}'",

filterPattern, dateTime2.AddDays(1).ToShortDateString());

dateColumn.CurrentFilterFunction = GridKnownFunction.GreaterThanOrEqualTo;

break;

case "LessThanOrEqualTo":

var dateTime3 = Convert.ToDateTime(filterPattern);

filterPattern = String.Format("[" + fieldName + "] > '{0}' AND [" + fieldName + "] < '{1}' OR [" + fieldName + "] <= '{0}'",

filterPattern, dateTime3.AddDays(1).ToShortDateString());

dateColumn.CurrentFilterFunction = GridKnownFunction.GreaterThanOrEqualTo;

break;

case "IsNull":

filterPattern = "[" + fieldName + "] IS NULL";

dateColumn.CurrentFilterFunction = GridKnownFunction.IsNull;

break;

case "NotIsNull":

filterPattern = "NOT ([" + fieldName + "] IS NULL)";

dateColumn.CurrentFilterFunction = GridKnownFunction.NotIsNull;

break;

}

foreach (GridColumn column in grid.MasterTableView.Columns)

{

if (column.UniqueName != columnUniqueName)

{

column.CurrentFilterFunction = GridKnownFunction.NoFilter;

column.CurrentFilterValue = string.Empty;

}

dateColumn.CurrentFilterValue = currentPattern;

grid.MasterTableView.FilterExpression = filterPattern;

filterItem.OwnerTableView.Rebind();

}

I have to admit that I have to use an old version of Telerik controls (Q3/2010 .NET 2.0) because the project needs to run under Mono.
Any help on this would be appreciated.

Best regards
Ferdinand
