I have the following ...
<asp:SqlDataSource ID="totalcount" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT COUNT ([CID]) FROM [WWAMembers] WHERE([CID] IS NOT NULL)"></asp:SqlDataSource>
how do I get the totals displayed with label or other control?
I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?
I have a gridview bounded to an objectdatasource.
I want to get total count of record when there is paging = true or false in gridview.
how to count total record in my data grid and after that export the records to excel ?
GridView id="grdCustomer"
void Data()
{
qry = "select * from customer order by customerId DESC";
DataSet ds = new DataSet();
ds = DBUtil.getTable(qry);
if (ds.Tables[0].Rows.Count != 0)
{
grdCustomer.DataSource = ds;
grdCustomer.DataBind();
}
else
{

I HAVE A GRID VIEW IN asp.net + VB Code. There is a drop down list and the selected data is displayed in web page. I placed a label in web page and code behind i used following code.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
Label1.Text = GridView1.Rows.Count.ToString()
Dim ONYO As Integer = 0
Dim DONE As Integer = 0
For i As Integer = 0 To GridView1.Rows.Count - 1
If GridView1.Rows(i).Cells(0).Text = "ON YO" Then

I want to get record count from below example.
I made two tables. One is club_info and another one is club_members.
And each table has data like following
[club_info]
club_id
club_name
:
[club_members]
mem_id
club_id
:
I want to get club_name and the member count for selected club_id and want to return the result as sqldatareader.
I wanted to get the total row count in a GridView's databound event handler, so I tried the following:
protected void grid_DataBound(object sender, EventArgs e)
{
GridView grid = (GridView)sender;
DataSet data = grid.DataSource as DataSet;
if (data == null)
return;
int totalRows = data.Tables[0].Rows.Count;
}
The problem is that the grid.DataSource property is null. The DataSourceID property is not null, so does that mean that I can't access the DataSource object in the DataBound event handler unless I assign the DataSource property directly?
Edit1: Here is the code in my GridHelper class for adding rowcount to the BottomPagerRow. I would like to get rid of the requirement to pass in the ObjectDataSource, but can't because I need to use the Selected event to get total row count. Hence the reason for the question. I also think this might be better in a custom control where I can access ViewState, and/or create child controls during the Init event (I still have a problem to resolve with the way the pager renders with an extra cell), but then I'd still have the problem of how to get to the total row count when the DataSource itself doesn't appear to be available in any GridView events.
Edit 2: Not really relevant to the specific problem, but I resolved the problem I was having with the pager rendering so i've updated the code posted. I found the trick here: [URL]

Is there any settings in gridview properties....
I'll start off with a snapshot of the application i'm working on.
Basically, what's going on is i'm using a bunch of sqldatasources to track truck loads (shown) based off a date/ date range. As there are generally multiple loads that all have the same information, so the information is grabbed with a SELECT DISTINCT so that you're only seeing one entry per multitude of loads. From there, customers can select the load type they want to work with and it goes into more detail, such as who trucked the different loads in, where it came from, where it's going to, references, that kinda stuff.
My question is, would it be feasible to show how many loads there are in total per distinct select? For instance, the top entry actually has 14 loads that are similar to that entry. How would I go about showing it has that total of 14 loads that could be shown?
I'm trying to use this code for counting and presenting total No. of rows returned for a grid view with AllowPaging="true" & PageSize="15".
getting the "object reference not set...." error for the "DataSet tbl" line:
[Code]....
in my asp.net+vb web there is a gridview in which i use a radiobuttion list as selectparameter. it works fine
there is a label in that page with code behind as under
Protected Sub RadioButtonList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadioButtonList1.SelectedIndexChanged
Label1.Text = GridView1.Rows.Count.ToString()
End Sub
count gets displayed but
if i select the first one at that time it will be 0
when i select the second one that time it shows the count of first selection
when i select the third one at that time it shows the count of second selection
I am using a grid view and a textbox(out of gridview to display the total rows in gridview) , i am doing Paging in GridView , and pageSize is set to 5 ; so far i did this
protected void ExistingMappedGrid_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
totalRowsLabel.Text = "Total " + ExistingMappedGrid.Rows.Count + " records.";
}
it shows the number of records , but not total ! it shows only the records displaying on the page .
e.g.
if i have a total of 8 records , not page index works and shows 5 rows in gridview and other 3 rows on 2nd page index , but if on first instane page shows 5 records in gridview then textbox shows 5 and when i click on second page index it shows 3 rows ( THAT"S NOT WHAT I CODED AND NOT NEEDED ) i want total rows to be shown
i have design a web application having suppliers table using SqlDatasource..
i have a master page in my design and other form are bound to a context menu..
Now i have displayed the records in the gridview..all i wanted is after i select a record in the gridview it will display the selected record in detailview from another aspx form..
i was able to create the link to another aspx form but the data that it display is the first data from the gridview not the data that i select.

I have data grid with page size 15. I need to find total number of record(s) in a grid. How to do it?There is two ways to do:
1) Here I have used LINQ. So calling stored procedure again and we can done using .Count () property. But here I don't want make call to data base again.2) Creating our own logic like here I have done like:
(dtgCustomerSearch.PageCount - 1) * (dtgCustomerSearch.PageSize) + dtgCustomerSearch.Items.Count
The above result gives me correct result only when I am on last page.

Then, I used variable Application["SiteHitCounter"] and Application[CurrentUsers"] in another C# behind code file to show them on web page.The problem I'm facing is that the website can't show right total visitor number as in my database when I publish it to shared host.

View 2 RepliesI'm using a stored procedure in a sql database as the data source for a SqlDataSourceControl on my .aspx page. I'm then using the SqlDataSourceControl as the data source for a gridview on my page. Paging is set to true on the gridview. What i would like to do is set the text of a label to the total number of rows in the gridview. I can use this code
'labelRowCount.Text = GridView2.Rows.Count & " layers found"
to return the number of results per page, but it doesn't give me the total.
i have in my asp.net web-page `label` that contain result of count record query.
i need to see refresh this query and see the correct record count.
how to see it ? i need any timer ? how to do it without Flickers ?
can i get any sample C# asp.net code ?
How to display the total number of records returned in a GridView in asp.net? I want to display it in a label or if possible next to the page index in GridView... And how to provide a select option in a GridView to select all records (It should select not only the record shown in one page in GridView but all records that were returned to the GridView) or one by one record that was returned? These things (for e.g., Number of selected rows) should also be displayed in the label which I mentioned before.
