                            DataTextField="ID" DataTextFormatString="Link" HeaderText="Linking">

   How do I need more than just the ID to DataNavigateUrlFormatString? For example, how do I add the Name field in addition to the ID to the end of the DataNavigateUrlFormatString?

Hello,

I've come up with a pretty good solution to the problem of needing to build
the NavigateUrl using multiple data values. My solution is partially based
on code from this article: http://tripleasp.net/tutorial.aspx?NavID=27

You need to use a TemplateColumn instead of a HyperLinkColumn. But in order
to build a TemplateColumn dynamically, you need a class that implements
ITemplate. I've created such a class which I feel solves this problem quite
nicely.

Using the class is as simple as:

TemplateColumn linkCol = new TemplateColumn();
linkCol.ItemTemplate = new MultiSourceHyperLinkTemplate("orderItemName",
"ShowItem.aspx?order={0}&item={1}",
new string[]{"orderNumber", "orderItemNumber"});
DataGrid1.Columns.Add(linkCol);

The above example assumes that orderItemName, orderNumber, and
orderItemNumber are all column names in the datasource for the datagrid.
The majority of the work is done by the MultiSourceHyperLinkTemplate class,
defined below:

public class MultiSourceHyperLinkTemplate : System.Web.UI.ITemplate
{
string m_DataTextField;
string m_DataNavigateUrlFormatString;
string[] m_DataNavigateUrlFields;

public MultiSourceHyperLinkTemplate(string dataTextField, string
navigateUrlFormatString, string[] navigateUrlFields)
{
m_DataTextField = dataTextField;
m_DataNavigateUrlFormatString = navigateUrlFormatString;
m_DataNavigateUrlFields = navigateUrlFields;
}

private void BindData(object sender, EventArgs e)
{
HyperLink link = (HyperLink) sender;
DataGridItem container = (DataGridItem) link.NamingContainer;
DataRowView curRow = (DataRowView) container.DataItem;
link.Text = curRow[m_DataTextField].ToString();
// evaluate each of the data fields
string[] navigateUrlValues = new string[m_DataNavigateUrlFields.Length];
for (int i = 0; i < m_DataNavigateUrlFields.Length; ++i)
navigateUrlValues[i] = curRow[m_DataNavigateUrlFields[i]].ToString();
link.NavigateUrl =
String.Format(System.Globalization.CultureInfo.Inv ariantCulture,
m_DataNavigateUrlFormatString, navigateUrlValues);

}

#region ITemplate Members

public void InstantiateIn(System.Web.UI.Control container)
{
HyperLink link = new HyperLink();
link.DataBinding += new EventHandler(BindData);
container.Controls.Add(link);
}

#endregion

#region Property accessors
string DataTextField { get { return m_DataTextField; } set {
m_DataTextField = value; } }
string DataNavigateUrlFormatString { get { return
m_DataNavigateUrlFormatString; } set { m_DataNavigateUrlFormatString =
value; } }
string[] DataNavigateUrlFields { get { return m_DataNavigateUrlFields; }
set { m_DataNavigateUrlFields = value; } }
#endregion
}

Hope it helps,

Hi, mychuncky

I find this post occasionally. Have you resolved it properly ?

If you are under ASP.NET 2.0，you can take the GridView and use the HyperLinkField that supports the NavigateUrlFields which can contain multi parameters.as following:

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
            AutoGenerateColumns="False" DataKeyNames="EmployeeID" DataSourceID="SqlDataSource1">
            <Columns>                
                <asp:HyperLinkField DataNavigateUrlFields="EmployeeID,PhotoPath" 
                    DataNavigateUrlFormatString="photo.aspx?empid={0}&path={1}"
                    HeaderText="Photo" Text="View Photo" />
            </Columns>
        </asp:GridView>

 Hope helpful!

Thanks Jinglecat. Now, that sounds much easier and less complicated. I'll give it a try.

Okay, here's what I have:

1    <div>
2            <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnStr %>"
3                SelectCommand="SELECT * FROM [Outlook]"></asp:SqlDataSource>
4        
5        </div>
6            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID"
7                DataSourceID="SqlDataSource1">
8                <Columns>
9                    <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True"
10                       SortExpression="ID" />
11                   <asp:CheckBoxField DataField="menu" HeaderText="menu" SortExpression="menu" />
12                   <asp:BoundField DataField="mnuOrder" HeaderText="mnuOrder" SortExpression="mnuOrder" />
13                   <asp:BoundField DataField="mnuLevel" HeaderText="mnuLevel" SortExpression="mnuLevel" />
14                   <asp:CheckBoxField DataField="visible" HeaderText="visible" SortExpression="visible" />
15                   <asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />
16                   <asp:BoundField DataField="title" HeaderText="title" SortExpression="title" />
17                   <asp:BoundField DataField="description" HeaderText="description" SortExpression="description" />
18                   <asp:CheckBoxField DataField="approve" HeaderText="approve" SortExpression="approve" />
19                   <asp:BoundField DataField="createDate" DataFormatString="{0:d}" HeaderText="createDate"
20                       HtmlEncode="False" SortExpression="createDate" />
21                   <asp:HyperLinkField DataNavigateUrlFields="ID,title" DataNavigateUrlFormatString="~/admin/detailPage.aspx?ID={0}&title={1}"
22                       DataTextField="ID,title" DataTextFormatString="Details" HeaderText="Details" />
23               </Columns>
24           </asp:GridView>

And I recieved this error on the masterPage.aspx page.

Okay, so if I don't have the field:

 DataTextField="ID,title"

<asp:gridvie id="gridview1" ruant="server">
<columns>
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink runat="server" 
    Text='<%# String.Format("photo.aspx?empid={0}&path={1}", Eval("EmployeeID"), Eval("PhotoPath")) %>'         
    NavigateUrl='<%# String.Format("photo.aspx?empid={0}&path={1}", Eval("EmployeeID"), Eval("PhotoPath")) %>'>
</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
....

Thanks!

this is really helpful, I have search on the internet find out about the multi field in a hyperlink also.
And then I finally borswe back to asp.net forum.... lol

Thanks too

I have a similar problem, but it pertains to dynamically displaying images in a DataList. I need to bind (or eval) multiple fields to an image url. Is there a similar solution for the ImageUrl property of an ASP:Image control?

 Here is my code to show you an example of what I am trying to accomplish:

<asp:DataList ID="AltPhotosDataList" DataSourceID="AltPhotoThumbsDataSource" runat="server" CellSpacing="5" HorizontalAlign="Center" RepeatColumns="5" RepeatDirection="Horizontal">
<ItemTemplate>
   <a href='<%# Eval("ProductID", "/Products/viewProductPhotos.aspx?ProdID={0}") %>' target="viewProductPhotosViewer" onclick="openRequestedPopup(this.href, this.target); return false;">
   <asp:Image ID="Image2" runat="server" ImageUrl='<%# Eval("PhotoPath, ProductID, FileName", "/Products/ProdImg/{0}/{1}/viewProducts/altViews/{2}") %>' AlternateText="Click to see more views"/></a>
</ItemTemplate>
</asp:DataList>
