I'm coding a report page.In this page,there are two date fields for user to filter the date and the GridView is filled depending on these dates in the CodeBehind (When user click the button view).Now I want toimplement a paging/sorting feature for this GridView.I've researched and see there are default paging for GridView which is not very efficient (my report table may have thousands of records) and custom paging but this requires using ObjectDataSource (which I don't use).Thus anyone can recommend me some approaches that are best used in this situation?

I am a beginner in Dot net Domain.Presently Im creating a web portal for one of our client.In my portal i have displayed the News headline and a button for details in a Grid view. when i click on the button it has to show the detailed news from DB in another grid view. I have done a code on it.,but it shows some error.I have displayed the code below.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType != DataControlRowType.Header && e.Row.RowType != DataControlRowType.Footer && e.Row.RowType != DataControlRowType.Pager) { Button btn = (Button)e.Row.FindControl("Button12"); btn.CommandArgument = e.Row.RowIndex.ToString(); } } protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName == "newsbtn") { int index = int.Parse(e.CommandArgument.ToString()); string key = GridView2.DataKeys[index].Value.ToString(); SqlDataAdapter da = new SqlDataAdapter("select **img,news,detail** from News where news=@n", connect.con()); da.SelectCommand.Parameters.AddWithValue("@n", key); da.Fill(ds, "more"); //if (!IsPostBack) //{ GridView1.DataSource = ds; GridView1.DataBind(); //} } }

A new route to an old problem for me... I'm creating radiobuttonlists and adding them to an update panel dynamically using this code:
[Code]....
I'm wanting to get the selected radio button value whenever a button on the page is pressed, however (and this is my old problem) I cannot retrieve that value. What I'm wanting to try is to add an event that will record the chosen radio button whenever the selected value has changed and store it into an array.
I have an update page with radiobutton "Alternate Addresses". If the radiobutton has "Yes" value, There would be altenate addresses for client. If radiobutton has "No" value, there won't be any alternate addresses. In update page, if supplier changes radiobutton value from "Yes" to "No" and clicks asp:Button "Update", all alternate addresses will be deleted. I want to show a confirm messagebox on Update button click. But i am not being able to retrieve radiobutton selected value in javascript.
var list = document.getElementById("radios"); //Client ID of the radiolist var inputs = list.getElementsByTagName("input"); var selected; for (var i = 0; i < inputs.length; i++) { if (inputs[i].checked) { selected = inputs[i]; break; }
This code works fine with html buttons. But I want code for asp:Button onClientClick.
