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'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
I have a gridView that shows the transaction_line table including "tL_id, t_id, date, pro_id, quantity, price, total price = quantity*price. How can I get a total transaction_line price for this gridView for each transaction_line id ??
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?
Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Label3.Text = GridView1.Rows.Count.ToString() End Sub
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 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") If CdDrive.SelectedItem Is Nothing Then Exit Sub Cd = CdDrive.SelectedItem.Value If os.SelectedItem Is Nothing Then NewPrice.Text = Format(473 + Proc + Ram + Hd + Cd + Window + Mon + sumList, "currency") If os.SelectedItem Is Nothing Then Exit Sub Window = os.SelectedItem.Value If Monitor.SelectedItem Is Nothing Then NewPrice.Text = Format(473 + Proc + Ram + Hd + Cd + Window + Mon + sumList, "currency") If Monitor.SelectedItem Is Nothing Then Exit Sub Mon = Monitor.SelectedItem.Value If Storage.SelectedIndex <> -1 Then For Each li In Storage.Items If li.Selected Then sumList += li.Value End If Next End If NewPrice.Text = Format(473 + Proc + Ram + Hd + Cd + Window + Mon + sumList, "currency") End Sub
When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
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.
I have a nested gridview like the code quoted below. How to retrieve the counter of each child gridview elements and display it as a field of the parent gridview ?
All radiobuttonlists and checkboxlist popluate from the database.comapring product productgroup and productvalue.after customer seleted items from these radiobutton list and checkboxlists iwant to create it as record to sttore in diffrent table with the all selected item + total price.so that in future we just serch record and we get it with and induval price and total price and seleted item.also its show image on selted items too.I dont know how to do it , I have MS ACESS database.I am using C# asp.net.I am working on it since last week.I dont know how i start it. I want to show image when it retrive the record which is customer seleted.
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]
