Hello Everyone,

I have a WPF datagrid. Also I have a method for copying the grid values.

I have prepared the grid values as HTML format before pasting into excel. It is working fine. But after pasting into excel the tag based content getting removed.

What I have tried:

Example :

The Format is,

<pre><TABLE>
<TBODY>
<TR>
<TD>ID</TD>
<TD>Text_Usage</TD>
<TD>TagName</TD>
<TD>Match_Condition</TD>
<TD>TagValue</TD>
<TD>UseText</TD>
</TR>
<TR>
<TD>1877</TD>
<TD>RC_Rules</TD>
<TD><User_notes></TD>
<TD>Contains</TD>
<TD>6239</TD>
<TD>59920</TD>
</TR>
</TBODY></TABLE>

But after pasting into excel, The below value has removed.

<pre><TD><User_notes></TD>

Actually here the <user_notes> is a column value. But html consider it as Tag. I think that's the reason it got removed after pasting into excel.

How could I resolve this problem?
