How to pass code behind variable via hyperlinkfield

Question

This is my code behind in C# .

protected void Page_Load(object sender, EventArgs e)
    {
           Name = "Nitin";                      
    }

I have a GridView in which there is a Hyperlinkfield.I want to send Name from C# page(one in code behind) to next page via HyperLinkField but it is not one of the BoundField's of the GridView(i.e. Which I get from EntityDataSource). This is my asp.net code.

code:

   <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Id" DataSourceID="WorkItemsEntityDataSource">
    <Columns>
        <asp:hyperlinkfield datatextfield="Id"                    
                datanavigateurlfields="Id"
                datanavigateurlformatstring="~\WorkItems.aspx?Id={0}"          
                headertext="Id"/> 
        <asp:BoundField DataField="Description" HeaderText="Description" SortExpression="Description" />
        <asp:BoundField DataField="TFSId" HeaderText="TFSId" SortExpression="TFSId" />
        <asp:CheckBoxField DataField="IsBillable" HeaderText="IsBillable" SortExpression="IsBillable" />
    </Columns>
</asp:GridView>

post your grid view code and elaborate ur problem clearly..

You can pass navigation URL from code behind also like this

In Aspx Page

              <asp:TemplateField>
                    <ItemTemplate>
                        <asp:HyperLink ID="hyp" runat="server" Text="Navigation"></asp:HyperLink>
                    </ItemTemplate>
                </asp:TemplateField>

In Code behind User grid view data bound event like this

protected void grddata_RowDataBound(object sender, GridViewRowEventArgs e)
    {    
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            int ID = Convert.Int32(DataBinder.Eval(e.Row.DataItem, "ID"));
            HyperLink hyp = (HyperLink)e.Row.FindControl("hyp");
            hyp.NavigateUrl = "Test.aspx?Name='" + Request.QueryString["test"] + "'&&ID"+ ID +"";
        }
    }

i think this will help you...

I'm not sure about using it in a data-bound control actually, but the url you are building definitely doesn't contain the QueryString parameter 'Name'. It should look like this:

~\WorkItems.aspx?Id={0}&Name={1}

of just replace the Id with Name if Id is not needed:

~\WorkItems.aspx?Name={0}

as for substitution - I don't know what properties does your data-object have and how to bind to them. I think you have no problem with it since binding to Id works (probably).

UPDATE

If Name is not returning from datasource, you should either create new entity which contains Name field as well, or use some constant name, like you are declaring in a page (not sure it this same name should be shown in every row). The second option can be implemented like this:

~\WorkItems.aspx?Id={0}&Name=<%= Name %>

You can use:

<asp:TemplateField HeaderText="test">
     <ItemTemplate>
           <asp:HyperLink runat="server" ID="temp" NavigateUrl='<%# String.Format("~\WorkItems.aspx?Id={0}&Name={1}",  Eval("Name"), Name)%>' ></asp:HyperLink>
      </ItemTemplate>
</asp:TemplateField>

You can modify a HyperLinkField's url by doing this:

protected void pendingAccountsGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        ((HyperLink) e.Row.Cell[0].Controls[0]).NavigateUrl = "http://stackoverflow.com";
    }
}

Just change it to specify the correct index in e.Row.Cell[0].
