Hello FRNDS, Please solve my problem facing with GRIDVIEW AND DROPDOWNLIST.
 
Am working on ASp.NET, c#, SqlSERVER2005.
 
On my webpage I have a Dropdownlist and a Gridview...data is dispalying perfectly from database. and this gridview contains PAGING ALSO(it contains Large number of records in GRIDVIEW) and the thing here is I need to sort the data based upon dropdown.
 
It should sort the complete column when selected from dropdownlist item.
 
In dropdownlist I used items as
1)sort by Employee name ---This must be sort alphabetwise A-Z
2)Sort by Hiring Date ---- Ascending order
3)Sort by Terminating Date --- Ascending Order.
 
When i select one item from Dropdownlist, that particular column must sort in Gridview.
 

Please help me, and solve this problem.
 
THANKS IN ADVANCE.

All you need is to sort the data based on a selection made in dropdown.

Hi,
 
Use this:
//Dropdownlist selected value changed event. This can be done on button click event also.
protected void DropDownList1_SelectIndexChanged(object sender, EventArgs e)        {
    gvSorting.Sort(DropDownList1.SelectedValue, SortDirection.Ascending);        
}
 
//Gridview sort command
protected void gvSorting_Sorting(object sender, GridViewSortEventArgs e)
{
    DataTable dtSortTable = gvSorting.DataSource as DataTable;
    if (dtSortTable != null)
    {
        DataView dvSortedView = new DataView(dtSortTable);
        dvSortedView.Sort = e.SortExpression + " " + getSortDirectionString(e.SortDirection);
        gvSorting.DataSource = dvSortedView;
        gvSorting.DataBind();
    }
}
 
//Getting the sort direction
private static string getSortDirectionString(SortDirection sortDireciton)
{
    string newSortDirection = String.Empty;
    if (sortDireciton == SortDirection.Ascending)
    {
        newSortDirection = "ASC";
    }
    else
    {
        newSortDirection = "DESC";
    }
    return newSortDirection;
}
 

 
All the best.
