Hi Telerik
I get this error when opening WebControl EditForm from a RadGridView. I am using latest version of Telerik. Just updated :)
0x800a139e - JavaScript runtime error: Sys.InvalidOperationException: Cannot serialize non finite numbers.
We suspect a bug of Telerik controls:
Bug of Telerik: PageView.set_contentUrl(MyUrl) method - call MyUrl twice if RadTabStrip and RadMultiPage is inside RadAjaxPanel control. Firefox only.
Code: http://bit.ly/2NVbm8Z
It enter here two times: http://bit.ly/2NZ0cQH
If try it in chrome - request goes only one time.
If remove RadAjaxPanel - also request goes only one time.
Is it bug of your Controls?
Ref. attached Image its show horizontal scrolling round with red color.
In business application more number of groups and menu item at that time horizontal scrolling very usefull as shown in the attached image
Hi, I have trouble with RadScriptManager. I would like combine scripts on page to only one file. But when I enabled it, my site threw javascript error on loading.
Please help me fix it, it would also be better if you can help me understand what happened.
First image is what I set up for RadScriptManager
Secondary image is the error.
I have no idea what's Telerik.Web.UI.Point, I haven't used it anywhere.
Please help me get this error out & fix it.
Thank you.
Would like to show column grouping for a few columns in the RaddGantt.
e.g.
- Planned Start and Planned End to be grouped under Planned
- Actual Start and Actual End to be grouped under Actual
- Financial Detail columns to be grouped under Task Financials
Also, would like to add to the query, how can I have the Gantt chart with the dates shown vertically as in the image attached. I don't want the Week or Month name coming in the grouping. Just dates in the timeline view.
Steps to repro:
1. Go to https://demos.telerik.com/aspnet-ajax/chat/toolbar/defaultcs.aspx
2. Show the toolbar with the ellipses
3. Enter enough messages so that the scroll is shown and continue to enter
4. The toolbar drop down on each click of an icon
See the attached video for more information.
Description:
If RadGrid has UseStaticHeaders enabled, different HTML Tables are rendered and instructing JAWS to read the tables one by one will also read the Header. It would say Header with "n" number of columns and one rows, since the table has only one row and that is containing the Column Names.
Goal:
It would be great, if the grid with Static Header could be made in a way that JAWS will only treat the grid as one Table instead of two separate tables.
We could use a new calendar control that works differently than the scheduler, or any existing calendar control.
Overview of features and how it would work:
- User selects a month, the calendar auto draws the month as a calendar view with options to set day of week as short, medium or full length.
- The calendar has an input field which can handle validation if needed. Validation example:
- Only accept integers
- In logic, if X = Whatever, then only allow input value of 1.
Treat as an array so we could loop through the control and read each value for saving to database or to take action on from code.
Example shown below. This is dynamically creating using tables and HTML. Not the nicest looking, and a pain to reuse anywhere. We could make use of this type of control in a lot of applications.
Steps to reproduce the error:
DataSource Bound to grid:
Private Function SomeTable() As DataTable Dim dt As New DataTable() dt.Columns.Add(New DataColumn("FieldName", Type.GetType("System.String"))) row("FieldName") = "C:\SomeDirectory\RadGridExport.pdf" dt.Rows.Add(row) Return dtEnd FunctionGridAttachmentColumn markup as well as the ObjectDataSource that returns a byte array when user clicks on download attachment:
<telerik:GridAttachmentColumn DataSourceID="ObjectDataSource1" HeaderText="Attachment Column" AttachmentKeyFields="FieldName" AttachmentDataField="FieldName" DataTextField="FieldName" UniqueName="FieldName" ButtonType="ImageButton" UploadControlType="RadAsyncUpload" FileName="RadGridExport.pdf" ImageUrl="pdf-icon.png" ItemStyle-Height="36px" ItemStyle-Width="36px" ></telerik:GridAttachmentColumn> <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="MySelectMethod" TypeName="MyApp"> <SelectParameters> <asp:Parameter Name="FieldName" Type="String" /> </SelectParameters></asp:ObjectDataSource>MyApp.MySelectMethod that is supposed access the file by "filePath" and read it to byte, but the filePath is malformed, hence throws an exception.
Public Class MyApp <DataObjectMethodAttribute(DataObjectMethodType.Select, True)> Public Function MySelectMethod(filePath As String) As DataTable Dim dt As New DataTable("Base") Dim col As New DataColumn("FieldName") col.DataType = System.Type.GetType("System.Byte[]") dt.Columns.Add(col) Dim row As DataRow = dt.NewRow row(0) = My.Computer.FileSystem.ReadAllBytes(filePath) dt.Rows.Add(row) Return dt End FunctionEnd Class

I am using the "PostbackTriggers" property of the Upload control, as described on your web site article "How to Persist Uploaded Files". This works well for the situation where I need a postback on a control, but that control is not a "submit" control. The problem comes when I use one of the "submit" controls (listed in the PostbackTriggers property), but a server side validation error occurs, and the form data (including uploaded files) is NOT saved to the DB. (This is a type of validation that can only be done on the server side.) In that case, the upload control loses the uploaded file information. Thus two questions: 1. Is there a way on the server side to tell the control that an error has occurred, and to continue to persist the uploaded file information? 2. Is there a way for the upload control to ALWAYS persist the uploaded file information until told on the server side that I have extracted the information I need from it?
Images that reside in the grid will get resized (scaled down with about 3-5 %) which might cause issues, specially if exporting bar-codes, thus the bar-code scanners won't be able to read them.
Current workaround is to use the Telerik Documents Processing Library and build the table manually where the images are inserted without changing the size.
Here is an example:
protected void RadGrid1_InfrastructureExporting(object sender, GridInfrastructureExportingEventArgs e)
{
Telerik.Web.UI.ExportInfrastructure.Table table = e.ExportStructure.Tables[0];
Workbook workbook = new Workbook();
workbook.Worksheets.Add();
Worksheet worksheet = workbook.ActiveWorksheet;
foreach (var row in table.Rows)
{
if (row.Index > 1)
{
worksheet.Rows[row.Index - 1].SetHeight(new RowHeight(55, true));
}
foreach (var cell in row.Cells)
{
if (row.Index == 1 || cell.ColIndex != 2)
{
worksheet.Cells[cell.Index.Y - 1, cell.Index.X - 1].SetValue(cell.Value.ToString());
}
else
{
FloatingImage image = new FloatingImage(worksheet, new CellIndex(cell.Index.Y - 1, cell.Index.X - 1), 0, 0);
Stream stream = File.Open(Server.MapPath(cell.Value.ToString()), FileMode.Open);
using (stream)
{
image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(stream, "jpg");
}
worksheet.Shapes.Add(image);
}
}
}
byte[] data;
using (MemoryStream ms = new MemoryStream())
{
XlsxFormatProvider xlsProvider = new XlsxFormatProvider();
xlsProvider.Export(workbook, ms);
data = ms.ToArray();
}
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.Headers.Remove("Content-Disposition");
Response.AppendHeader("Content-Disposition", "attachment; filename=" + RadGridLista.ExportSettings.FileName + ".xlsx");
Response.BinaryWrite(data);
Response.End();
}
Would be great if font awesome could be used for the radgrid edit/delete/ icons etc....
Simple reproducible is attached to illustrate the problem.
A workaround may be replacing RadButtons that invokes such postbacks with regular buttons and using a form decorator
Alternatively, you can simply disable the handler URL encryption
You can also put the following in the global.asax file to prevent the version from rendering on the page markup
protected void Application_BeginRequest(object sender, EventArgs e)
{
System.Web.HttpContext.Current.Items["_!TelerikVersionStampRendered"] = true;
}
or you can add the same line in a global Page_Load handler (e.g., in a base page class or in the master page your project uses)
