ExportToPDF exception

[Adam]

Hi,

I'm having a similar issue as the one reported here- http://www.telerik.com/community/forums/aspnet-ajax/grid/pdf-exporting-error.aspx

Essentially you get this exception when using the method-

System.Xml.XmlException: The '*' character, hexadecimal value 0x2A, cannot be included in a name.

I did some debugging and found this in the markup:

<span id="RadGrid1_ctl00_ctl03_ctl01_ChangePageSizeLabel" class="rgPagerLabel">Page size:</span>
<div id="RadGrid1_ctl00_ctl03_ctl01_PageSizeComboBox" class="RadComboBox RadComboBox_Default " style="width:46px;display:-moz-inline-stack;display:inline-block;zoom:1;*display:inline;margin-left:-1px;margin-right:-1px;white-space:normal;">

The offending character comes after the 'zoom:1' style on the RadComboBox generated for the grids page size selector (it says 'zoom:1;*display:inline;'  notice the *).

Is this a bug in the RadComboBox or RadGrid or is there some way to remove this style?

[Daniel]

Hello Adam,

The problem is that RadComboBox uses special CSS approach that is incompatible with the PDF XSLT transformation. The easiest way to sidestep this error is to set ExportOnlyData to true.

<ExportSettings ExportOnlyData="true" />

When I set that property, it now gives me this error-

Hello Adam,

Could you please attach a runnable version (preferably simplified) of your project to a formal support ticket? I would like to debug it locally if possible. Otherwise, if the code is not so lengthy, you can post it here in this thread.

I've got a trimmed down sample working and I'm sending it to my co-worker so he can open the ticket on his account (the license for the RadControls and support options are linked to his account).

[Daniel]

Hello Adam,

Thank you for the sample code. I examined it locally and found what's causing the error. Please modify your code this way:

foreach (GridHeaderItem headeritem in RadGrid1.MasterTableView.GetItems(GridItemType.Header))
{
    headeritem["exCol"].Text = "<a href='javascript: ExpandCollapseAllTables()' id=\"btnEx\">Expand</a>";
}

Thanks for your help Daniel, the modification seems to work.

Daniel,

I am facing an issue while exporting the grid as PDF especially one specific grid ,where in the other one its working perfectly.Below is the error System.InvalidCastException : Unable to cast object of type "Telerik.Web.Apoc.Layout.BlockArea' to type 'Telerik.Web.Apoc.Layout.AreaContainer'. I came to know that are some other developers faced the issue and recommended not have width or height attributes in % instead as px,also to set ignorepaging =false ,I tried those as well but still not working. Please help me to get a workaround for this.

Hello Udaya,

There are two reasons for this error in your scenario:
- DIV element with hardcoded size (width, height)
- DIV with position: absolute

ExportDataOnly is a bit of a meagre solution if you want to export images.

[Daniel]

Hello Brady,

Try one of the following workarounds:

protected void RadGrid1_PdfExporting(object source, GridPdfExportingArgs e)
{
    e.RawHTML = e.RawHTML.Replace("*display", "display");
}

or:

protected void Button1_Click(object sender, EventArgs e)
{
    foreach (GridPagerItem item in RadGrid1.MasterTableView.GetItems(GridItemType.Pager))
        item.PagerContentCell.Controls.Clear();
    RadGrid1.MasterTableView.ExportToPdf();
}

Note, that none of these suggestions will affect the actual page but only the PDF file.

Thanks Daniel, but I've come right with a simple solution for now:  a Pager Mode of NumericPages removes all the uglies and all works quite well.

[Udaya Kumar]

Thanks Daniel,I had sorted out the issue by hiding the header.
