I don't want my OnRowCommand to execute for the first column of my GridView. Actually I don't want my event to fire when some of my checkboxes is clicked. How to determine if I have clicked on a checkbox or I have clicked somewhere else in a gridview? In WPF I could use e.OriginalSource property but here this is not possible.


Using JQuery:
If you haven't already added JQuery to your page, add this tag to your page's head section:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
And this is the actual code. Add this after the link to JQuery, in the .aspx page's head section:
<script type="text/javascript">
$(function(){
$('#<%= GridView_Messages.ClientID %> input[type="checkbox"]')
.click(function(event){
event.stopPropagation();
event.preventDefault();
})
});
</script>

How can I add static text as Footer at the bottom of the GridView?

I am trying to add a Foot Note at the bottom of the Grid. but from the below code snippet, I am seeing footnote at the bottom but it is coming in the empty columns. I mean to say if I have 4 columns in the Grid, the Foot Note is displaying after the 4th column. this should not happen. Ideally, the footnote will starts from the first column until the end of the grid. (as a row)
Any suggestions, please?

How to retain multiple dropdown list's selected value even when page index is changing?

I'm a newbie in asp.net development. Any help would be much appreciated. :)
What I need to accomplish is to retain the selected value of my drop down lists in my gridview even when the user navigate to the next page index. I am thinking to put the values into session while page are changing and put it back when the page shows again.

Hope you binding a DataTable to GridView.
Save the Data Table which you are binding to the GridView and Update the Same DataTable something like beow.
gvwAssociation_PageIndexChanging(object sender,GridViewPageEventArgs e)
{
DataTable dt = (DataTable)Session["SavedDataTable"];
foreach (GridViewRow gvRow in gvwAssociation.Rows)
{
DropDownList ddlpool = (DropDownList)gvRow.FindControl("ddlpool");
DropDownList ddlyear = (DropDownList)gvRow.FindControl("ddlyear");
if (dt.Select("ID=" + gvRow.Cells[1].Text).Length > 0)
{
dt.Select("ID=" + gvRow.Cells[1].Text)[0]["Pool"] = ddlpool.SelectedValue;
dt.Select("ID=" + gvRow.Cells[1].Text)[0]["Year"] = ddlyear.SelectedValue;
}
}
Session["SavedDataTable"] = dt;
gvwAssociation.PageIndex = e.NewPageIndex;
gvwAssociation.DataSource = dt;
gvwAssociation.DataBind();
}

My gridview is inside an update panel. The textboxes are doing some mathematical calculations in side the gridview in their TextChange Event and autopostback is true for them.
Whenever I am pressing tab for moving the cursor to the next textbox the page gets postbacked and the scroll position is not maintained. How will I solve this?

Maintain a scrollable gridview position on postback inside update panel

I have a gridview with overflow-y:auto. The gridview is inside an update panel which is wrapped in a user control. This usercontrol is displayed using the ajax modal pop up extender. Now, this gridview could have hundreds of items, if a user would have to select an item, then the async postback reloads the popup again and the scroll position is lost. I tried with the solution posted on the link http://weblogs.asp.net/andrewfrederick/archive/2008/03/04/maintain-scroll-position-after-asynchronous-postback.aspx as well but no luck. Not sure if I am misplacing the javascript code.
This is where I have the modal pop up extender.
<asp:Panel ID="pnlShowDirectMailMedium" runat="server" Visible="false" HorizontalAlign="Center">
<uc2:DirectMailMedium ID="ucDirectMailMedium" runat="server" OnCloseEvent="ucDirectMailMedium_CloseEvent" />
<asp:HiddenField ID="hfCloseDMMedium" runat="server" />

TargetControlID="hfCloseDMMedium" PopupControlID="pnlShowDirectMailMedium" OkControlID="hfCloseDMMedium"
CancelControlID="hfCloseDMMedium" Drag="true" RepositionMode="None" />
This is the actual user control where i have the gridview.

Could someone give me an insight on what to do. FYI - The scriptmanager is on the master page.

You need to do like this ,
full detail : Maintain Scrollbar Position Inside UpdatePanel After Partial PostBack
You need to write down javascript which is part of image for maintaining scroll position

Since your gridview is located inside the user control that would be the appropriate place to add the code for maintaining the scroll position.
One important thing worth mentioning is that the javascript needs to be executed once the DOM is fully loaded, this can be done as follows:
Use #Pranay Rana's method and place the script after the ScriptManager control
Add a reference to jQuery and use $(document).ready()...
Here's a simple example of how this can be done, I'm sure you can modify this accordingly to work for your scenario :-)
ASPX:
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="UserControl1.ascx.cs"
Inherits="WebApplication16.UserControl1" %>
<script src="Scripts/jquery-1.7.1.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var xPos, yPos;
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_beginRequest(BeginRequestHandler);
prm.add_endRequest(EndRequestHandler);
function BeginRequestHandler(sender, args) {
xPos = $get('scrollDiv').scrollLeft;
yPos = $get('scrollDiv').scrollTop;
}
function EndRequestHandler(sender, args) {
$get('scrollDiv').scrollLeft = xPos;
$get('scrollDiv').scrollTop = yPos;
}
});
</script>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div id="scrollDiv" style="overflow:auto;height: 100px;" />
<asp:GridView ID="gvEmployees" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:CommandField ShowSelectButton="true" />
<asp:BoundField DataField="Name" />
</Columns>
</asp:GridView>
</div>
</ContentTemplate>
</asp:UpdatePanel>
Code behind:
public partial class UserControl1 : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
gvEmployees.DataSource = new List<Employee>
{
new Employee{Name="Employee 1"},
new Employee{Name="Employee 2"},
new Employee{Name="Employee 3"},
new Employee{Name="Employee 4"},
new Employee{Name="Employee 5"},
new Employee{Name="Employee 6"},
new Employee{Name="Employee 7"},
};
gvEmployees.DataBind();
}
}
}
public class Employee
{
public string Name { get; set; }
}

now i want to sort them renthourly and rentdaily in ascending and descending order

Looks like this is an old question, but your best bet is to use an ObjectDataSource to bind your grid.
Once you use the ObjectDataSource, you can have it automatically supply the SortDirection, SortColumn, CurrentPage and PageSize to the SelectMethod you have specified on the ObjectDataSource.
Inside this business method (your SelectMethod) you can cleanly issue the appropriate command to query only the data needed for the current page and apply the appropriate sorting expression.
