Accessing Row in GridView

I have the following ASPX code:

<ItemTemplate>
    <asp:HyperLink ID="BRANCH_NAME" runat="server" 
          NavigateUrl='<%# "mailto:"+Eval("OWNERS_EMAIL") %>' 
          Text='<%# Eval("BRANCH_NAME") %>' 
          ToolTip='<%# GetBranchAddress() %> '> 
    </asp:HyperLink>
</ItemTemplate>

The function in the code behind:

protected string GetBranchAddress(DataRow row)
{
    return "<span style=\"text-decoration:underline;\">"+ 
               row["BRANCH_NAME"].ToString().Trim() + "</span><br />" + 
               row["OWNERS_FIRST_NAME"].ToString().Trim() + " " +
               row["OWNERS_LAST_NAME"].ToString().Trim() + "<br />" + 
               row["OWNERS_EMAIL"].ToString().Trim() + "<br />" + 
               row["OWNERS_OFFICE_PHONE"].ToString().Trim() + "<br />" + 
               row["OWNERS_FAX_PHONE"].ToString().Trim();

}

The error I get is:

No overload for method 'GetBranchAddress' takes '0' arguments

How can I access row in my ASP GridView so that I can pass it to my function?

Thanks.

Instead of trying to pass the entire DataRow into the function, utilize datakeys to specify the fields you want to display, and pass in the row index.

<asp:GridView ID="GridView1" runat="server" DataKeyNames="BRANCH_NAME, StreetAddress" ...>

The code in the ItemTemplate would look something like this:

<ItemTemplate>
    <asp:HyperLink ID="BRANCH_NAME" runat="server" 
          NavigateUrl='<%# "mailto:"+Eval("OWNERS_EMAIL") %>' 
          Text='<%# Eval("BRANCH_NAME") %>' 
          ToolTip='<%# GetBranchAddress(Container.DisplayIndex) %> '> 
    </asp:HyperLink>
</ItemTemplate>

In your function, you can access the datakey values like this:

protected string GetBranchAddress(int rowIndex)
{
    return GridView1.DataKeys[rowIndex]["BRANCH_NAME"].ToString();
}

In your markup, you're not passing any parameters in to GetBranchAddress, which is why you're getting the error. You should pass "this" into the method, where "this" is the currently operated on object (the DataRow). For example,

ToolTip='<%# GetBranchAddress(this) %> '
