计算启用分页的网格视图中的条目数

Question

I have a TextBox in which I want to display the number of entries in my GridView .

count2.Text += (GV.Rows.Count).ToString();

Paging is enabled but it counts only the entries in the first page.

How do I ensure that it counts all entries ?

I tried this :

         <asp:SqlDataSource ProviderName="System.Data.SqlClient" ID = "sourceProducts" runat = "server" ConnectionString =" <%$ ConnectionStrings:DB %> " SelectCommand = "myqueryhere"  OnSelected="sourceProducts_Selected">




protected void sourceProducts_Selected(object sender, SqlDataSourceStatusEventArgs e)
    {
        z = e.AffectedRows;
    }

But this gives me some wrong value

Answer 1

Take a step back. Where did you get the data from? If you are binding to a data table then just count the rows there. If calling to a stored proc with parameters for start and end rows and getting a table back, change it to send a dataset back. The first table in the dataset would be your data, the second a table just containing the count.

Answer 2

You can use Selected event of SQLDataSource , and fetch the number of records using Affected property like this:-

protected void sourceProducts_Selected(object sender, SqlDataSourceStatusEventArgs e)
{
    count2.Text = e.AffectedRows.ToString();
}

Edit:

protected void Page_Load(object sender, EventArgs e)
{
    System.Data.DataView dataView = (DataView)sourceProducts
                                              .Select(DataSourceSelectArguments.Empty);
    count2.Text = dataView .Count.ToString();
}

Answer 3

Just check this, what will be the result in your selected method

protected void sourceProducts_Selected(object sender, SqlDataSourceStatusEventArgs e)
{
int startRowOnPage = (GridView1.PageIndex * GridView1.PageSize) + 1;
    int lastRowOnPage = startRowOnPage + GridView1.Rows.Count - 1;
    int totalRows = e.AffectedRows;

    count2.Text = "Showing " + startRowOnPage.ToString() +
                  " - " + lastRowOnPage + " of " + totalRows;
}
