asp.net: ListView on the masterpage - asp.net

Question

I have some asp.net pages.
I used the masterpage to implement common control.
There is a listview on the masterpage.
And there is a label on the contentpage.
I want to implement below.
When user select a node on the listview of masterpage,
the label text on the contentpage is changed into the text of the node.
How can i implement this.
Could you give me some advice or some link about my question?
Thank you in advance.

Answer 1

On Master1.master, I used ItemCommand event on ListView
<form id="form1" runat="server">
<asp:ListView ID="List1" runat="server" onitemcommand="List1_ItemCommand">
<ItemTemplate>
<p>
<asp:label ID="ItemLabel" runat="server" text="<%#Container.DataItemIndex %>" />
<asp:LinkButton ID="ItemLink" runat="server" CommandName="SelectItem" Text="Select" />
</p>
</ItemTemplate>
</asp:ListView>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</form>
And Master1.master.cs, store selected item text to public property
public partial class Master1 : System.Web.UI.MasterPage
{
public string selectedText { get; set; }
protected void List1_ItemCommand(object sender, ListViewCommandEventArgs e)
{
if (e.CommandName == "SelectItem")
{
selectedText = ((Label)e.Item.FindControl("ItemLabel")).Text;
}
}
}
Then in Content1.aspx , add a label with id Label1
<asp:Label ID="Label1" runat="server" />
Finally in Conetnt1.aspx.cs, read the property "selectedText" on prerender event (which comes after select click)
protected void Page_PreRender(object sender, EventArgs e)
{
var myMaster = (Master1)this.Master;
Label1.Text = myMaster.selectedText;
}
