Hi,

hyperlink column.


public MemoryStream GetMinuteOrderPdf(SearchParams sp)
{
DMS dms = new DMS();

sp.IsMinuteOrder = true;

return dms.getDocument(sp);//it returns the PDF memory stream
}




ASPX code:

<asp:TemplateColumn HeaderText="Minute Order" >
<ItemTemplate>
<asp:HyperLink

</asp:TemplateColumn>


Please help me how can i call this function.Is there any way to do
this?

You can't do it from a hyperlink column as that does not create the event. If
you MUST use a hyperlink column, then call a new page (or pass a querystring
parameter to this page) and call the function from that.

You would normally use a linkbutton or button to cause an event, then in
that event, generate your PDF.

Hope this helps.

Thanks for your suggestion.So you meant to say that the below code will
work assuming that i declared linkbutton in the datagrid control:

protected void grdMinSearch_ItemDataBound(object sender,
DataGridItemEventArgs
e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
LinkButton btn = e.Item.FindControl("linkView") as
LinkButton;
Minute Min=new Minute();

e.Item.Attributes["onclick"] =
Min.GetMinuteOrderPdf(SearchParams sp);


btn.Style[HtmlTextWriterStyle.Display] = "none";


}
}

Please comment on this.

Thanks,
Vishnu

Hi,

I can't see anything wrong with that, though there may be some others with
more experience than me that might be able to see any potential issues.
