Session in databinding....

[bobetko]

How can I include session variable in databinding.
Example:

<asp:ImageButton ID="btnPreview" runat="server"  OnCommand="ImagePreview_Command" CommandArgument='<%# Session["UserFolder"] + "images/" + Eval("filename") %>'/>

I would like commandArgument of above image button to be something like:
Session["UserFolder"] + "images/" + Eval("filename")

How to do this properly?

Thanks

should I rewrite the question? This one should be easy!?

Write a function to return the string with the value of your session variable

Your asp:ImageButton attribute:

CommandArgument='<%# GetUserFolder(filename) %>'

Your .Net code

protected void GetUserFolder(string strFileName)
{
   return Convert.ToString(Session["UserFolder"]) + "images/" + strFileName;

}

hth


}

Oops the function call should be

CommandArguement='<%# GetUserFolder(Convert.ToString(Eval("filename"))) %>'

 

[bobetko]

GetUserFolder function is returning a value, so protect string... instead of protect void ....

Works great, thank you. I didn't have idea what to google to look for this answer.

Thanks.
