Hello Partha,

Check the following help documentation which explains about Exceptions incurred when exporting to pdf. Hope this helps.
PDF export.

Thanks,

Princy ,

I am presently using a commanditem template and also I have some nested controls inside that.So I think there is some issue with the commanditem template and the nested controls.  I am using paging for the grid.


Thanks,
Partha.

[Partha]

Hi,
May be the cause for the exception is if you have commandItemTemplate, and nested controls in it. The controls from the command item which is embedded in the resulting document is multiplied for all pages.How to solve this problem?

Thanks,
Partha.

[Princy]

Hello Partha,

I am not sure whether you want to export the controls inside CommandItemTemplate. If not try to set ExportOnlyDara as 'True' like below.

<ExportSettings ExportOnlyData="true">
 </ExportSettings>

Thanks,
Princy.

[Partha]

Princy,

I need to have  the command template item in the exported file.So I cannot make ExportOnlyData="true".Please suggest a workaround.


Thanks,
Partha.

Hi Jayesh,

I am already using   <MasterTableView  Width="100%" TableLayout="Fixed" in my code .But is seems it is not working.


Thanks,

Hello,

Please suggest a solution to this problem.I have noticed that it is happening only when we have pagination in the grid. For a single page in the grid it is working fine.Can that be a problem?

Thanks,
Partha.

Hi guys,

I recommend that you try to hide the pager item (on ItemCreated) before exporting.

Resolved the issue.We have to use use  asp literal control instead of asp label control. It is working properly now.Issue was happening only when pagination was involved.

Thanks,
Partha.
