I'm generating a number of calculated arrays in the code behind a ButtonClick event on a particular page. Stuff like:
Dim Delta(,) As Double = New Double(nPer - 1, 0) {}
For i = 0 To nPer - 1
Delta(i, 0) = Delta_Buckets(i, 0) + fwds(i, 0)
Next
What I want to do is convert this to a datatable and use this as a datasource for a gridview in a different page.
in my webform --
when user input the valid data then there will be generate a areport and that report displays in a gridview itemtemplate. when i print the report, only first page data printed properly on a predesigned designed paper. and others are not. then how to print each rowdata of gridview on per page.
I'm not sure how to search for what I'm seeking, so I'm hoping to be pointed in the right direction.
I have 4 gridviews that contain the same 3 rows of data. For each gridview, I need to create a seperate gridview that will do some calculated values on the parent gridview like A3-A1, to put it in spreadsheet terms.
And at the very bottom I will have a total gridview control that will sum up each row from the parent gridviews. And under that gridview a final gridview to perform the A3-A1 calculation.
In parent page there is an imagebutton. What I want to when user click this image button, another page will open with width=200 and height=100 with no toolbar.

I have a Gridview that has a template field containing a bound textbox (fieldname is 'Status'). I have an extra column containing an update button, which is designed to update the db with whatever is in the textbox.
What's happening is that when I load the form, the textbox is blank, even though there is existing data in the fields. If however I click the update button, all the textboxes in the Status column update and populate with the correct data from the database. I guess my question is why would bound textboxes not populate until an update command is run?
I am developing an application using Sharepoint Designer.I need to retrieve data from a database for display on the screen.The way I am hoping to implement this is to have a Text box from which data is taken and at the click of a button passed to the procedure (which is within script tags) which calls a stored procedure passing it the value entered in the text box.The problem I've having is that the gridview is not displaying anything (i.e. other than text i entered in the EmptyText property of the gridview ("There are no records").

I have a simple aspx page with a GridView Bound to an ObjectDataSource utilizing a class object that returns a DataView.
There are no errors generated, but the GridView does not display any rows. If I check the return value of the ObjectDataSource in the Selected event in the Immediate window (?CType(e.ReturnValue,DataView).Count), there are 51 rows. However, (?Me.GridView1.Rows.Count) shows 0 rows. The exact same page in VS2008, ASP.NET 3.5 works fine. how to get the GridView to display the rows? What has been done to the GridView in 4.0?

Does anyone know if it is possible to create a gridview from a class on a seperate webpage?
So I have webpage 1, that calls Class 1, in Class one there will be a Select Query that will call some info from a database and then return it to a gridview. The gridview wont work obviously as it is in the class and not on webpage 1.
Is there anyway to reference the fact I would like the gridview created on webpage1?
i am displaying a gridview from db(SQL2005), which display leave table where employee apply leave and submit to admin. Viewing the leave table in gridview the admin sanction or rejected their leave request, by clicking the check box displays on each gridview rows and click on sanction or rejected button.
here i am sending SMS to the employee number displaying in the gridview (taking the employee phone number and send SMS).. this i have done using bulk SMS services, i have taken the number using the following
if check conditions...
but now what the problem is i have to delete the gridview rows.. i am using the same employee phonenumber to delete the corresponding gridview, but if suppose the single employee applied for two or more leave, the gridview display all leave for the single employee, the admin have sanction only one leave for that employee.. so if he checks the check box and click on OK button.. it have to delete the corresponding row as well as send SMS to the phonenumber of the employee.. Other leaves of the same employee display in the gridview.. i used the following coding
Protected Sub bttnsanction_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bttnsanction.Click
Dim row As GridViewRow
Dim selection As New ArrayList()
For i As Integer = 0 To GridView1.Rows.Count - 1.........
I am using the Sno as primary key in leave table.. where i want to delete the corresponding row which sends SMS to employee number also the delete the row of corresponding Sno.. i have to get the corresponding gridview row sno in the delete store procedure..
during edit mode i populate the drop down in question with data based on a value selected in another drop down also in the gridview, all works find, but the paramater is not being updated with the selected value, i think this is because i do not call any Bind in the aspx side.

<ItemTemplate>
<asp:Label ID="lblBuildTypes runat="server" Text='<%# Bind("BuildType") %>'></asp:Label>

I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?
View 3 Repliesi have a need to display the each row in a separate page,
example: if a Grid view contains the 10 rows,each row should be displayed in one page(only that row only),when ever second row comes, first row should be removed from grid and second row should be displayed as a whole in that, like wise..when ever 3rd row comes 2nd should be erased and 3rd will come into Grid view.
i am using following code but not getting result as i want,
foreach (GridViewRow gr in GridView1.Rows)
I need to create a TemplateField column dynamically , which will contain dropdowlist controls. I've been using this
example to create my first dynamic columns and for the last column, the one that contains dropdowlist controls, I've written this class:
[Code]....
But what I don't know is, where should I populate the dropdownlist control?
I have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?

I have two dropdown lists that I am using to filter a gridview. I gridview is populating based on a query
select [AnnotationNumber],[AnnotationBy],[AnnotationType],[BusinessUnit] as Unit,[ErrorType],[ActualAgencyError],AnnotationComments,[sgkComments],[ActualAgencyError],Cust from vw_GridviewSource where Name = '"+@Name+"' and AnnotationDate = '"+@Stage+"'";
SqlCommand cmd = new SqlCommand(query);
gvSummary.DataSource = GetData(cmd);
The @Name and @Stage variables are the selected values of the dropdownlist. When I start I get the two drop down lists on my webform. When I select the values from the dropdownlists, nothing happens. I get no gridview. I added onselecedindexchange event both dropdownlists and even after both are selected nothing. I debugged the code and found that there is a point where the value is correct, but I still don't see the gridview. I have alsochecked the query associated with the databind and it works perfectly when I check it in SQL. I am enclosing all the code from the aspx.cs and aspx.

I read your article on ASPSnippets and everything worked great. I am having one problem and this is preventing me from moving forward. When I select the edit for a row (I only have two columns), the drop down comes back blank (no records). I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list? I can't tell if the column automatically adjusts because I am not returning any records.

I have access to two seperate databases (mySQL) located on two servers. I need to get the data, link the tables on a key field and display the results in a datagrid. My challenge is that if the search criteria changes for the display it affects rows returned from on table and should thus automatically affect the linked table and resulting data returned.
what the best approach would be to achieving this? So far I have set up a dataset with a dataadapter and table for each connection and then linked the tables in the dataset. The problem that I'm having is getting the linked resultsets to work.
On my form I have the datagrid with two Objectdatasources one for each dataadapter and i believe that's where I'm going wrong...
I have a complicate problem. I'm not sure if I can explain it clearly. I have SQL table with columns: id, PartNo, ManuPartNo, GovtPartNum.
My boss want to do like this with 3 dropdown or 1 Dropdown with 2 listbox: If he select any PartNo, it will pull associated value For ManuPartNo & GovtPartNum
Also, if he select any ManuPartNo, it will populate back to other dropdown
Also, if he select any GovtPartNum, it will populate back to other dropdown
I'm so stuck & I don't know where to start on this.
