i wanna Get Selected Value for SqlDataSource's Select Parameter located in Content Page from ListBox located in Master Page ? So how can i do that ?

Thanks in Advance..

Write a public property in the MasterPage that returns the ListBox text/value, so that you can call it in your contentpages.

public partial class MasterPage1 : System.Web.UI.MasterPage
{
    public string ListBoxValue {
        get { return ListBox1.SelectedItem.Value; }
    }
    protected void Page_Load ( object sender, EventArgs e) { .... }
}

In you ContentPages, you can access it, by  calling ListBoxValue property

Thanks

wow that was really nice method like it :) thanks and i'll mark your answer as an answer like how you said you footer text :) thanks again by the way...

but i would like you to answer something for me again..if i want to pass this value to sqldatasource select paramater, how can i do that ? i mean for example how can i reach specific select parameters value and put a value in it. for example again :) : you gave me a method to get the value from selected index of ListBox control located in Master Page and i want to use this value for SqlDataSource (located in Content Page) Select parameters referring to a condition in where statements and in according to this statement there are some datas being called from database and binded to detailsview. and which event of sqldatasource i should use and put my code under... ?

Thanks in advance...

Depending on the event in which you want to bind the datasource, you can set the SqlParameters on the datasource. If you want to bind it in the Page_Load

protected void Page_Load (object sender, EventArgs e)
{
    // set the parameters
    SqlDataSource1.SelectParameters["parameter name"].DefaultValue = ListBoxValue; // ListBoxValue from MasterPage
    // bind to the detailsview
    DetailsView1.DataSource = SqlDataSource1;
    DetailsView1.DataBind();
}

Thanks
