I want to apply custom pagination to my gridview which contains itemtemplate
which has a image that comes from the database
I have tried with clientid mode static but that didnt work out
My Procedure:-
create procedure sp_BookingByPageSize
#pageNo int,
#NoOfRecord int,
#TotalRecord int output
as
select #TotalRecord =
count(*) from tblDiscount
select * from
(
select
Row_number() over
(order by r.bookingid asc)
as RowNo,
r.BookingId,
u.Fullname,
h.hotelName,
case when r.bookingstatus=1 then 'Confirmed'
when r.BookingStatus=0 then 'Cancelled'
end as Booking_Status
,r.Check_In,r.Check_Out,r.NoOfGuests,ro.RoomTypeName,r.NoOfRoomsBooked,r.NationalID,r.Amount from tblReservation as r inner join
tblHotel as h on r.HotelId=h.HotelID
inner join tblUser as u
on u.UId=r.UId inner join tblRooms as ro on ro.RoomsID=r.RoomType)
AS Tab
where tab.RowNo between((#PageNo-1)*#NoOfRecord)+1 and (#PageNo*#NoOfRecord)
order by 2 asc
return

MyCode behinde:-

using System.Web.UI;
using System.Web.UI.WebControls;
using HotelBAL;
namespace HotelReservation.Views
{
public partial class AdminViewBooking : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
PopulateData(1, 5);
}
AddpaggingButton();
}
private void PopulateData(int pageNo, int noOfRecord)
{
GridView1.DataSource = BookingBal.PopulateData(pageNo, noOfRecord);
GridView1.DataBind();
ViewState["TotalRecord"] = BookingBal.getTotalRecord1();
ViewState["NoOfRecord"] = BookingBal.getNoOfRecord1();
}
private void AddpaggingButton()
{
int totalRecord = 0;
int noOfRecord = 0;
totalRecord = ViewState["TotalRecord"] != null ? (int)ViewState["TotalRecord"] : 0;
noOfRecord = ViewState["NoOfRecord"] != null ? (int)ViewState["NoOfRecord"] : 0;
int pages = 0;
if (totalRecord > 0 && noOfRecord > 0)
{
pages = (totalRecord / noOfRecord) + ((totalRecord % noOfRecord) > 0 ? 1 : 0);
for (int i = 0; i < pages; i++)
{
Button b = new Button();
b.Text = (i + 1).ToString();
b.CommandArgument = (i + 1).ToString();
b.ID = "Button_" + (i + 1).ToString();
b.CssClass = "btn btn-outline-warning";
b.Click += new EventHandler(this.b_click);
Panel1.Controls.Add(b);
}
}
}
private void b_click(object sender, EventArgs e)
{
//this is for get data from database from clicking button
string pageNo = ((Button)sender).CommandArgument;
PopulateData(Convert.ToInt32(pageNo), 5);
}
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
}
}
}
Here b_click should work but it is not working any help would be appreciated as I am new to this custom paging
I myself solved the problem by using a generic handler

I Have a Table column Called Status which takes three Values 1, 2 or 3. Now, I want to Display another column Name1 in either of the three GridViews depending on the Status. Also I have link buttons which Redirect to different web forms.
This is the output I'm Getting. The ID of this GridView is GridView1

I am working on a Cart project, and using Visual Studio 2010 with SQL server express. I am using a Gridview to display data from my cart table in my database. I have a product table in my database , and I insert products from product table to the cart table . after that i display the cart in the gridview. the problem I am facing is i cannot use the Price column from my gridview to add the prices of the items in the cart to display the total price of the order. how can i do that?

If I am understanding your question correctly, what you are wanting to know about is the SQL function "SUM". You can find more information about sum here. The short version is that SUM returns the total for a column of NUMERIC data. The basic syntax looks something like this:
SELECT SUM(myColumn)
FROM myTable;
/* Assume myColumn contains {0, 1, 2, 3, 4, 5} */
/* The output of this SELECT statement would be {15} */
I am not getting the point why this is happening.
I have a Gridview, inside that I have implemented a pagerTemplate. It is showing me the correct records which are coming from the database.
First of All, I took the logic of implementing the gridview pager part from here. And I implemented the same as described their.
Now the scenario which I came up with is that, When I change the dropdown selection, my gridview gets postback and all the Row of the grid gets disturbed. I dont know why this is happening.
See the code which I implemented:-
<asp:GridView ID="grdCSRPageData" runat="server" Width="100%" border="1" Style="border: 1px solid #E5E5E5;" CellPadding="3"
AutoGenerateColumns="False" OnDataBound="grdCSRPageData_DataBound" AllowPaging="true" CssClass="hoverTable" EmptyDataText="No Records Found"

<Columns>
<asp:TemplateField HeaderText="Select" HeaderStyle-Width="5%" HeaderStyle-CssClass="k-grid td">

<asp:CheckBox ID="chkSelect" runat="server" AutoPostBack="false" />

<td style="width:70%; text-align:right">
<asp:label id="CurrentPageLabel" runat="server"/>
</td>
</td>
</tr>
</table>
</pagerTemplate>
</asp:GridView>
The code is added with PagerTemplate. Also see my code behind as given their:-
Cs Code for the PagerTemplate:-
protected void grdCSRPageData_DataBound(object sender, EventArgs e)
{
GridViewRow pagerRow = grdCSRPageData.BottomPagerRow;
DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
Label pageLabel = (Label)pagerRow.Cells[0].FindControl("CurrentPageLabel");
if (pageList != null)
{
for (int i = 0; i < grdCSRPageData.PageCount; i++)
{
int pageNumber = i + 1;
ListItem item = new ListItem(pageNumber.ToString());
if (i == grdCSRPageData.PageIndex)
{
item.Selected = true;
}
pageList.Items.Add(item);
}
}
if (pageLabel != null)
{
int currentPage = grdCSRPageData.PageIndex + 1;
pageLabel.Text = "Page " + currentPage.ToString() +
" of " + grdCSRPageData.PageCount.ToString();
}
}
protected void PageDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow pagerRow = grdCSRPageData.BottomPagerRow;
DropDownList pagelist = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
grdCSRPageData.PageIndex = pagelist.SelectedIndex;
}
Please help. Any help would be appreciable
try changing the AutoPostBack="true" to false of your dropDownList and be sure to load data in Page_Load inside
if (!IsPostBack){
//bind gridview
}
update
try inserting your dropDownList (with AutoPostBack="true") and your GridView inside an UpdatePanel with "UpdateMode=Conditional" like this
<asp:UpdatePanel runat="server" ID="up1" UpdateMode="Conditional">
<ContentTemplate>
//put here gridview
<ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="PageDropDownList" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
update

I have a gridview that I need a footer row inserted with the data from a textbox when the user hits submit. I have tried over and over and I can not get past the following error:
Object reference not set to an instance of an object. The error is flagged on the Textbox AddName line of code in the code behind.

It looks like your SqlDataSource2 is causing the error. Please double check that both Name and Email are of DB type string in your DB.
In your ASPX SqlDataSource2 make the following changes:
<InsertParameters>
<asp:QueryStringParameter Name="Name" QueryStringField="Name" DbType=String />
<asp:QueryStringParameter Name="Email" QueryStringField="Email" DbType=String />
</InsertParameters>
In your C# Code-Behind, change to this:
SqlDataSource2.InsertParameters[0].DefaultValue = txtAddName.Text;

Thanks!
Try this
protected void GVProducts_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//your code
if (!abort)
{
connection = new Connect(Server.MapPath("App_Data/ado1.mdb"));
OleDbCommand cmd = new OleDbCommand();
cmd.CommandText = "Update Products Set amount=" + amount + ", minAmount=" + minAmount + " Where phoneId=" + id;
cmd.ExecuteNonQuery();//OR "connection.ChangeDatabase(cmd);" if it updates your database
products = connection.GetData("Select * From Products", "Products");
GVProducts.EditIndex = -1;
GVProducts.DataSource = products;
GVProducts.DataBind();
UpdateGVlabel();
MessageBox.Show("המכשיר נערך בהצלחה!");
}
}
The problem was you were calling connection.ChangeDatabase(cmd); to update your database after fetching data from table like this products = connection.GetData("Select * From Products", "Products"); hence you always got old values from your db and values in your db also got updated too..
Also add this GVProducts.DataBind(); after providing datasource GVProducts.DataSource = products; to bind the grid.
Write The code in the row updating
int i=convert.toint32(e.NewValues["Standard"])
IsPostBack() is the answer. We have to check if the Page is posted back or not. If not, then we will bind the Grid.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}
}
