image not exporting on radgrid exporttopdf

[Mehreen]

I am unable to get the image to export on the pdf. Here is my code:

protected void RadGrid1_PdfExporting(object sender, GridPdfExportingArgs e)
{

string tableWrapper = string.Empty;
tableWrapper = "<table><colgroup><col style='width:550px;' /></colgroup>";
tableWrapper += "<thead></thead><tbody><tr><td>" + e.RawHTML + "</td></tr>";
tableWrapper += "<tr><td>&nbsp;</td></tr>";
tableWrapper += "<tr><td>&nbsp;</td></tr>";
tableWrapper += "<tr><td style='padding-left:5px;'>" + AddPDFTables() + "</td></tr>";
tableWrapper += "</tbody><tfoot></tfoot></table>";

e.RawHTML = tableWrapper;
}

private string AddPDFTables()
{
string tables = string.Empty;

tables += "<?hard-pagebreak?>";
tables += "<table style='border-style:none; width:550px; font-size:8px; padding-left:2px; padding-right:2px; padding-top:2px;'>";
tables += "<colgroup><col style='width:200px; vertical-align:top;' /><col style='width:20px;' /><col style='width:200px; vertical-align:top;' /></colgroup>";
tables += "<thead></thead><tbody>";
tables += "<tr><td>" + CreateLegendPDF() + "</td><td>&nbsp;</td><td>" + CreateRejectCodePDF() + "</td></tr>";
tables += "</tbody></table>";

return tables;
}

private string CreateLegendPDF()
{
string legend = string.Empty;

legend += "<table style='border-style:solid; border-color:#5d8cc9; border-width:1px; width:200px; font-size:8px; padding-left:2px; padding-right:2px; padding-top:2px; padding-bottom:2px;'>";
legend += "<colgroup><col style='width:30px;' /><col style='width:150px;' /></colgroup>";
legend += "<thead><tr><th colspan='2' style='background-color:#bdcbde; font-weight:bold; font-size:9px; text-align:left; padding-left:2px;'>Content Areas</th></tr></thead>";
legend += "<tbody>";

if (listLegendRows.Count <= 0)
{
listLegendRows = (List<string>)ViewState["LegendList"];
}

if (listLegendRows.Count > 0)
{
foreach (string item in listLegendRows)
{
legend += item;
}
}
legend += "</tbody></table>";

return legend;
}

private string CreateRejectCodePDF()
{
string rejectString = string.Empty;
List<string> listRejectRows = new List<string>();

if (ViewState["RejectList"] != null)
{
listRejectRows = (List<string>)ViewState["RejectList"];
}

if (listRejectRows.Count > 0)
{
rejectString += "<table style='border-style:solid; border-color:#5d8cc9; border-width:1px; width:200px; font-size:8px; padding-left:2px; padding-right:2px; padding-top:2px; padding-bottom:2px;'>";
rejectString += "<colgroup><col style='width:30px;' /><col style='width:150px;' /></colgroup>";
rejectString += "<thead><tr><th colspan='2' style='background-color:#bdcbde; font-weight:bold; font-size:9px; text-align:left; padding-left:2px;'>ARDMS Reject Codes</th></tr></thead>";
rejectString += "<tbody>";

foreach (string item in listRejectRows)
{
rejectString += item;
}
rejectString += "</tbody></table>";
}
return rejectString;
}

 

 

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
if (isPdfExport)
{
GridItem item = e.Item as GridItem;
item.Style["font-family"] = "Segoe UI";
item.Style["font-size"] = "8px";

switch (item.ItemType) //Mimic RadGrid appearance for the exported PDF file
{
case GridItemType.CommandItem:
item.Style["display"] = "none";
item.Visible = true;
item.Style["background-color"] = "#000000";
break;
case GridItemType.Item:
item.Style["background-color"] = "#FFFFFF";
break;
case GridItemType.AlternatingItem:
item.Style["background-color"] = "#e8f1fc";
break;
case GridItemType.Header:
item.Style["background-color"] = "#bdcbde";
break;
case GridItemType.FilteringItem:
item.Style["display"] = "none";
item.Visible = false;
break;
case GridItemType.Footer:
item.Style["background-color"] = "#c3d8f1";
break;
}

if (item is GridCommandItem)
{
item.PrepareItemStyle(); //needed to span the image over the CommandItem cells
}
}
}

 

 

 

 This is the error I am getting

[GridPdfExportException: Invalid XHTML. RadGrid has to render correct XHTML in order to export to PDF.
Parse error:
The 'tbody' start tag on line 674 position 83 does not match the end tag of 'thead'. Line 687, position 4.
at line:
</thead><tbody>]

 

 

 

I checked all the tags and they seem fine to me.

How do I correct this?

Thanks,

Hello Mehreen,

This error occurs when there is a forgotten closing/opening tags and the XHTML validation fails. I would recommended to get the modified RawHTML and use the W3C validator to check for errors in the HTML.

For some reason, I am not able to modify the margins on the exported grid. Its moved to the right  of the page. I used

PageLeftMargin="20mm" 
                        PageRightMargin="20mm" 

but its ignoring anything i put in these settings. How can I center justify the grid on the exported pdf?

Hi Mehreen,

In order to center the RadGrid control you should simply remove its width instead of setting any page properties. This way the RadGrid will be with width 100% and will automatically center on the page.
