GridView HyperLink field in C#

Question

Take a look at the following code:

Answer 1

Use the DataNavigateUrlFields property, comma-delimited value with the fields for parameters in "KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}"

<asp:HyperLinkField DataNavigateUrlFields="Keyword,State,City"
                    DataNavigateUrlFormatString="KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}" 
                    Text="View Details" />

A couple of examples:

Passing two arguments in DataNavigateUrlFormatString in hyperlink field of .NET 2.0 Grid-View

Pass Multiple Values from a GridView to Another Page using ASP.NET

EDIT:

Set NavigateUrl of HyperLink in RowDataBound event of GridView

<asp:GridView ID="GridView1" runat="server" 
              AutoGenerateColumns="False" 
              DataKeyNames="Keyword"
              DataSourceID="SqlDataSource1" 
              onrowdatabound="GridView1_RowDataBound">
   <asp:TemplateField HeaderText="Keyword"  ItemStyle-HorizontalAlign="Center"          FooterStyle-HorizontalAlign="Center">
      <ItemTemplate>
          <asp:HyperLink ID="link" runat="server" Text='<%# Eval("Keyword") %>' />
      </ItemTemplate>
    </asp:TemplateField>
    .......
</asp:GridView>

Code behind:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
 if (e.Row.RowType == DataControlRowType.DataRow) 
 { 
    HyperLink hl = (HyperLink)e.Row.FindControl("link"); 
    if (hl != null) 
    { 
        DataRowView drv = (DataRowView)e.Row.DataItem; 
        string keyword = drv["Keyword"].ToString(); 
        string state = Request.QueryString["State"]; 
        string city = Request.QueryString["City"]; 
        hl.NavigateUrl = "~/KeywordSrchSumDtl.aspx?Keyword=" + keyword + "&State=" + Server.UrlEncode(state) + "&City=" + Server.UrlEncode(city); 
    } 
 } 
}

Answer 2

You may initialize DataNavigateUrlFields from Code Behind with string[]:

yourHyperLinkField.DataNavigateUrlFields = new string[] { "Keyword", "State", "City" };

Answer 3

Finally it Navigates by the following code,

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
 if (e.Row.RowType == DataControlRowType.DataRow) 
 { 
      HyperLink hl = (HyperLink)e.Row.FindControl("Link");
      if (hl != null)
      {
           DataRowView drv = (DataRowView)e.Row.DataItem;
           string keyword = drv["Keyword"].ToString().Trim();
           string state = strState.ToString().Trim();
           string city = strCity.ToString().Trim();                 
           hl.NavigateUrl = "KeywordSrchSumDtl.aspx?Keyword=" + keyword + "&Geo=" + geo                             + "&Site=" + site;
       }
       }
      }

Thank u guys for the help.

Some time we need to pass multiple parameters with hyperlink in Gridview, datagrid or any data list control then we can use following code:-</br> 

**CODE:-** 
<asp:GridView ID="gvFin" runat="server" CellPadding="1" AutoGenerateColumns="false"> 

<Columns>
     <asp:TemplateField ItemStyle-Width="4%" HeaderStyle-Width="4%" SortExpression="CDL"
    HeaderText="CDL#" HeaderStyle-Font-Bold="true">
                                                <ItemTemplate>
   <asp:HyperLink ID="lnk1" runat="server" 
   Text='<%# DataBinder.Eval(Container.DataItem,"TestValue") %>'
   NavigateUrl='<%# "javascript:ShowACP(\"" + DataBinder.Eval(Container.DataItem, "ID")     + "\",\"" + DataBinder.Eval(Container.DataItem,"ACCOUNTPLAN") + "\");" %>'                                                  ForeColor="Blue" /  </ItemTemplate>
 </asp:TemplateField>


**JavaScript Function**

function ShowACP(id, acplabel) 
{            if (acplabel == "No")
{
                window.location = "#";
            }
            else</br> 
                window.location = "Default.aspx?gid=" + id;
        }

Answer 5

You can try with string.Format method

NavigateUrl='<%# String.Format("KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}", DataBinder.Eval(Container.DataItem, "Keyword"), Request.QueryString["State"], Request.QueryString["City"]) %>'
