please tell me wot to do

I guess you need to set DataKeyField property of DataList control with your prison_event_id .

thanx.I changed my code a bit...

        DataList dlEvntDetails = (DataList)dlEvents.SelectedItem.FindControl("dlEvntDetails");
        BLL_NewsAndEvents objNE = new BLL_NewsAndEvents();
        objNE.viewEvntDetails(dlEvntDetails, txtEvntDesc.Text.Trim(), lblEvntVenue.Text.Trim(), lblEvntDate.Text.Trim(), lblEvntTitle.Text.Trim(), lblEvntId.Text.Trim());
        objNE.Close();
    
    }

but the values are not gettin passed to the codebehind...please tell me wot to do

can you please show the code of method viewEvents(this.dlEvents) and viewEventDetails() ? also i think you need to use ItemCreated or ItemDataBound event to show the other details you want...

public void viewEvents(System.Web.UI.WebControls.DataList dlToFill)
    {
        string[] arrParam = new string[1];
        arrParam[0] = "NA";
        bislogic objBis = new bislogic();
        objBis.populate_dataList(arrParam, dlToFill, "usp_event_viewDL");
        objBis.Close();
    }

when i try to put prison_event_id as datakeyfield the datalist doesnot display anythin....

im trying to get the name of the datalist that is nested within the main datalist in the selectedIndexChanged event...
i'm doing the following:

protected void SelectedIndexChanged(object sender, EventArgs e)
    {
        //string title = dlEvents.DataKeys[dlEvents.SelectedIndex].ToString(); 
        BLL_NewsAndEvents objNE = new BLL_NewsAndEvents();
        objNE.title = dlEvents.DataKeys[dlEvents.SelectedIndex].ToString();
       
        DataList dlEvntDetails = (DataList)dlEvents.FindControl("dlEvntDetails");
        objNE.getEvntDetails(dlEvntDetails);
        string id = objNE.Id.ToString();
        string title = objNE.title.ToString();
        //DateTime evntdate = objNE.evntDate;
        string venue = objNE.venue.ToString();
        string desc = objNE.Description.ToString();

but im not getting any value...please tell me how to get the name

i tried putting it in the ItemCommand Evnt

protected void getSelected(object source, DataListCommandEventArgs e)
    {
        dlEvents.SelectedIndex = e.Item.ItemIndex;
        DataList dlEvntDetails = (DataList)e.Item.FindControl("dlEvntDetails");
        BLL_NewsAndEvents objNE = new BLL_NewsAndEvents();
       objNE.title = dlEvents.DataKeys[dlEvents.SelectedIndex].ToString();
      
       objNE.getEvntDetails(dlEvntDetails);
        Label lblEvntId = (Label)e.Item.FindControl("lblEvntId");
        Label lblEvntTitle = (Label)e.Item.FindControl("lblEvntTitle");
        Label lblEvntDate = (Label)e.Item.FindControl("lblEvntDate");
        Label lblEvntVenue = (Label)e.Item.FindControl("lblEvntVenue");
        TextBox txtEvntDesc = (TextBox)e.Item.FindControl("txtEvntDesc");
        //DataList dlEvntDetails = (DataList)e.Item.FindControl("dlEvntDetails");
        BLL_NewsAndEvents objNe = new BLL_NewsAndEvents();

       // objNe.viewEvntDetails(dlEvntDetails, txtEvntDesc.Text.Trim(), lblEvntVenue.Text.Trim(), lblEvntDate.Text.Trim(), lblEvntTitle.Text.Trim(), lblEvntId.Text.Trim());
        objNe.Close();
    }
