sorting a gridview

[wrexhamafc234]

hello, im trying to sort a gridview

protected void Page_Load(object sender, EventArgs e)
    {
        DataTable alerttable = new DataTable("alerttable");
        alerttable.Columns.Add("ID");
        alerttable.Columns.Add("Title");
        alerttable.Columns.Add("Section");
        alerttable.Columns.Add("Priority");
        alerttable.Columns.Add("AlertDate");
        alerttable.Columns.Add("Type");
        alerttable.Columns.Add("Details");
        alerttable = AlertDataFunctions.GetAllAlertDetails(userID, sort, ViewType.Text);

        GridView1.DataSource = alerttable;
        GridView1.Sorting += new GridViewSortEventHandler(GridView1_Sorting);
        if (AlertName.Checked == true)
        {
            GridView1.Sort("Title", SortDirection.Ascending);
        }
        else if (Date.Checked == true)
        {
            GridView1.Sort("AlertDate", SortDirection.Ascending);
        }

        GridView1.DataBind();
}

    void GridView1_Sorting(Object sender, GridViewSortEventArgs e)
    {


    }

However, im not too sure what to put into the GridView1_Sorting function.

Any ideas?

1. put your page_load into a seperate event and call it like below (call LoadData() whatever you want).
2. seems in your theory, the sort will depend on a checkbox, that will hold its value between postbacks, only if you check for postback as below, so just call your void again in the sorting event, and it might work for you.

protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
              LoadData();
        }
    }

public void LoadData();
    {
        DataTable alerttable = new DataTable("alerttable");
        ...
    }
    public void GridView1_Sorting(Object sender, GridViewSortEventArgs e)
    {
        LoadData();
    }
