Question

Gridview Hyperlink in ASP.NET 2.0 using VB

Asked by: eciabattari

Hi - have a GridView to show data within a table format.  The columns are bound.  How would I make a particular column value a hyperlink?

Is there a way, instead of making the asp:BoundField, I could use asp:Hyperlink; however, how would I populate?

Here's the code that I'm using to create table:

              <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
                  AutoGenerateColumns="False" DataSourceID="SqlDataSource1" Height="40px" Width="722px">
                  <Columns>
                      <asp:BoundField DataField="Shift" HeaderText="Shift" SortExpression="Shift">
                          <HeaderStyle BackColor="#E0E0E0" />
                          <ItemStyle BackColor="White" BorderColor="Transparent" Width="150px" />
                      </asp:BoundField>
                  </Columns>
              </asp:GridView>

Here's the code that is generating the SqlDataSource.

    Private Sub GenerateGridQueryString()

        strGridString = "SELECT tblShift.Shift, tblUnit.Unit_description, tblPriority.Priority_description, "
        strGridString &= "tblLog.Log_Note, tblLog.tag_number, tblOperator.NTID, tblPriority.Priority FROM tblLog "
        strGridString &= "INNER JOIN tblShift ON tblLog.ShiftID = tblShift.ShiftID INNER JOIN tblPriority ON "
        strGridString &= " tblLog.priority_id = tblPriority.priority_id INNER JOIN tblUnit ON tblLog.unit_id = tblUnit.unit_id"
        strGridString &= "  INNER JOIN tblOperator ON tblShift.OperatorID = tblOperator.OperatorID"
        strGridString &= " WHERE (tblShift.Shift = '" & strShiftID & "')"

        SqlDataSource1.SelectCommand = strGridString

    End Sub

Hi,

Try this.

aspx part

<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False">
         <Columns>
           <asp:TemplateField HeaderText="Name">
                    <ItemTemplate>
                        <a href= '<%# Eval("Link") %>'  runat ="server" id="ref"> <%# Eval("Link")%> </a>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Name">
                    <ItemTemplate>
                            <asp:Label ID="Label2" runat="server" Text='<%# Eval("Name")%> '></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                 <asp:TemplateField HeaderText="No">

Hi,

Try like this.


    Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then
            if Convert.ToString(e.Row.Cells(0).ToString()).Trim() != "" then
                Dim htmlAnc As New HtmlAnchor
                htmlAnc.HRef = "http://www.google.com?Search=" & Convert.ToString(e.Row.Cells(0).ToString())
                htmlAnc.InnerHtml = "<b>" & Convert.ToString(e.Row.Cells(0).ToString()) & "</b>"
                e.Row.Cells(0).Controls.Add(htmlAnc)
            End If
        End If
    End Sub

Change the cell column "cells(0)" as required.

Hi eciabattari,

You can use a Hyperlink field..

For example:

<asp:HyperLinkField HeaderText="your header" DataTextField="The field you want to display" DataNavigateUrlFields="The field that will provide the navigation, usually an ID field" DataNavigateUrlFormatString="yourpage.aspx?id={0}" />

Regards,
Max.
