Dear sirs,
I have taken hyperlink inside the gridview.how i want to pass one value from one page to another by clicking hyperlink which is inside the gridview.Coding in design page is
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="id" DataSourceID="SqlDataSource1"
onselectedindexchanged="GridView1_SelectedIndexChanged">
<Columns>
<asp:BoundField DataField="id" HeaderText="id" InsertVisible="False"
ReadOnly="True" SortExpression="id" />
<asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />
<asp:BoundField DataField="Lname" HeaderText="Lname" SortExpression="Lname" />
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink ID="hp" Text="pass value" NavigateUrl="~/AA.aspx" runat="server"></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:QConnectionString %>"
SelectCommand="SELECT [id], [name], [Lname] FROM [registration]">
</asp:SqlDataSource>
<br />
<br />
</div>
</form>
</body>
在页面后面的代码是:
In page behind code is:
public partial class Default7 : System.Web.UI.Page
{
string ss;
SqlConnection cn = new SqlConnection(@"Data Source=.\sqlexpress;Initial Catalog=Q;Integrated Security=True");
protected void Page_Load(object sender, EventArgs e)
{
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
foreach(GridViewRow gr in GridView1.Rows)
{
HyperLink idd = (HyperLink)gr.FindControl("hp");
if (idd)
{
ss = gr.Cells[2].Text;
}
Session["dd"] = ss.ToString();
}
}
}
在另一个页面中的编码是:
In another page coding is:
public partial class AA : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Label1.Text = Convert.ToString(Session["dd"]);
}
}
您能帮我解决这个问题吗?
在此先感谢.
Can you help me to solve this problem.
Thanks in Advance.
推荐答案
ConnectionStrings:QConnectionString ％> " span> =" 从[注册]中选择[id]，[name]，[Lname]" < /asp:SqlDataSource > < br > < br > < /div > < /form > < /body >
ConnectionStrings:QConnectionString %>" SelectCommand="SELECT [id], [name], [Lname] FROM [registration]"> </asp:SqlDataSource> <br /> <br /> </div> </form> </body>

如果您想从超链接进行重定向，则可能需要在href的末尾附加一个要传递的信息的querystring参数，然后将其解析出来.
If you want to redirect from your hyperlink, you may want to append a querystring argument to the end of the href with the information you want to pass and then parse it out of there in the consuming page.
string strLink1 = "Page.aspx?id=" +value + "& name=" +value + "";
((HyperLink)e.Row.Cells[i].Controls[1]).Attributes.Add("onclick", "open_win('" + strLink1 + "')");
使用这个人.
