Set Label Text To Total Row Count Of Gridview?

Jun 3, 2010

I'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.

Forms Data Controls :: Adding A Total Load Count To The Gridview?

Jan 13, 2010

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?

May 7, 2015

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)

Web Forms :: Checkboxlist Not Getting Added To Total Price

Mar 23, 2011

I have a bunch of radiobuttonlists and one checkboxlist that when selected they are supposed to get added to a price total. All of the radiobuttonlists work correctly in adding to the price but the checkboxlist doesn't get added when one is selected. Here is the code I am using:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
NewPrice.Text = Format(473, "currency")
Dim Proc, Ram, Hd, Cd, Window, Mon As Integer
Dim li As ListItem
Dim sumList As Integer = 0
If processor.SelectedItem Is Nothing Then NewPrice.Text = Format(473 + Proc + Ram + Hd + Cd + Window + Mon + sumList, "currency")
If processor.SelectedItem Is Nothing Then Exit Sub
Proc = processor.SelectedItem.Value
If Memory.SelectedItem Is Nothing Then NewPrice.Text = Format(473 + Proc + Ram + Hd + Cd + Window + Mon + sumList, "currency")
If Memory.SelectedItem Is Nothing Then Exit Sub
Ram = Memory.SelectedItem.Value
If HardDrive.SelectedItem Is Nothing Then NewPrice.Text = Format(473 + Proc + Ram + Hd + Cd + Window + Mon + sumList, "currency")
If HardDrive.SelectedItem Is Nothing Then Exit Sub
Hd = HardDrive.SelectedItem.Value
If CdDrive.SelectedItem Is Nothing Then NewPrice.Text = Format(473 + Proc + Ram + Hd + Cd + Window + Mon + sumList, "currency")

Forms Data Controls :: Gridview Row Count / How To Get A Count Of The Number Of Rows That Are Returned

Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

Get Total Row Count And Why Is The GridView's DataSource Property Null In The DataBound Event Handler

Jul 22, 2010

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]
