I have the following page and what I'd like to be able to do is that when the user clicks on the clear button that it disposes of the results of the datagridview and reloads the page.
Imports System.Data.SqlClient

I have a working code that exports the datagrid into XLS. However, the datagrid results does not show on my aspx (html) page. It only shows on the page when I comment out the part that exports it to xls. I am not sure whether it should show by default when exporting.Basically, what I want to have is when I click my export button, it should display the datagrid on the page as well as popup an excel "open, save, cancel" window for the export.
Here is my function for referece:
Public Sub Convert(ByVal ds As DataSet, ByVal Response As HttpResponse)
Dim attachment As String = "attachment; filename= ExportPRFs_" & Today() & ".xls"
[code].....
I am binding a dataset (dsTest) with a table called "TempResult" to a datagrid (DatagridView1).The purpose of the datagrid is to display test labels (set elsewhere in the software) and to allow the user to enter results into an empty column titled results.To achieve this I've filled the dataset with the required test labels then added a column called "Result" with a default value of 0.00.The user can enter numbers into the "Result" column on the grid then click a button "ADD" to update the changes to the datatset,When I first open the form the datagrid shows the correct information and any changes made to the Result column are updated correctly - all is well.
Private Sub Add_Results()
Dim ResultColumn As DataColumn
Dim Rows As Integer
Dim i As Integer
[code]....
If I close the form and open it up again (i.e. the user wants to add more results) the datagrid shows the results entered the last time the form was use and any changes made to the grid are not updated and the form won't work again until the software is reloaded.
I have sub routine that is called via events like so.
Private Sub dgvQA_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvQA.RowEnter
The problem is, is that it only fires correctly once.The e event variable keeps the same row even though I have now clicked on a new row.Meaning the next time an event occurs it has the same values as the previous event, when they should be different.How do I make it return the correct rows value when called the next time?The sub, depending on what row is select, creates a new form like the following
Dim NewForm As QA
NewForm = New QA
NewForm.UseParm = 1
NewForm.ShowDialog(Me)
Which is then worked with and closed, there after the sub continues normally.The sub also calls a different sub which may alter text fields within the datagrid view refreshing the data to reflect the work within the form that was created and used.

I have a form that uses the printer object and the print preview. A user clicks on a Print button, the preview comes up. This works fine the first time they do so, but if they click on this button more times, the output is overlaid ontop of the first report. The printer object is destroyed at the end of the print creation, and I have tried various other means to make sure that the page gets cleared without success.[code]
View 20 Repliesi am new at everything VB.net/ASP.net. I have an ASCX.vb page that lets the user choose someone from a table. Once they do select someone, the page reloads with that persons information into another table below that one where they can submit an order for that person or remove that person. Problem being is that i wanted to store the users ID that are selected but it seems that everytime the page reloads to show an update, it dim's my array again back to default. This is my code once they choose a user:

I have a webapp in ASP.Net with a VB codebehind. I need a List variable I have declared to persist as long as the person is on the page, but currently any time a control posts back to the code, everything is cleared out. Can it be done with a Session variable? Those seem to me to be limited to base types, but I could be wrong.
View 4 RepliesI am creating a notes software. This is just a simple application that will show the data from the database which are Notes_Title, Due_Date, Priority. I display the data with datagridview. I also added a checkbox for each row to the datagridview to mark as check if the Notes_title is already done. In displaying the data, I need to display only a 5 data in a row.So, I create a another CLASS that will only show 5 rows per page. But the PROBLEM is, if I mark the checkbox as check in the first page then if I turn it to the next page the checkbox in the first page that mark as check will be uncheck if I turn it back to the first page. The mark check in the checkbox will mark as uncheck if I turn the page. How can I make it mark as check even if I turn the pages? And How can I save the data row as done if I check

Datagrid with results form sql query

View 3 RepliesI'm using Visual Studio 2005, and I have a datagrid connected to a table from an Access database.
I added 4 textboxes so the user can type search filters to search within the table and a "search" button.
Then, I created a query using the "add query" tool on the datagrid. I wrote it like: select field1, field2, field3, field4, field5, field6 from table where field1=? and field2 like "%"+?+"%" and field3 like "%"+?+"%"
and field4 like "%"+?+"%"
Both field5 and field6 aren't search criterias, so I didn't add them to the query. Once the query was created, I replaced the parameters inside the procedure with my textbox1.text, textbox2.text, textbox3.text, textbox4.text and then cut and pasted the whole thing inside my SEARCH button click event, so the query is executed when the user clicks on the button.
Now the problem is: when I search using the first field it goes ok, but when I try to search by any of the other fields it returns zero results, even though I double-checked I had written the words correctly. I don't know why it does this. I already tried deleting the datagrid and creating it again.[code]...
I have a program I wrote a few years back and I brought it back to life with a search feature.I am using an XML file to store the data in.I have a search function that will display the first result from the textbox1.text value,it displays it in a messagebox.

View 1 RepliesI am developing an ASPX web page to return results from two SQL stored procs via VB. When I execute these two stored procs, they both return valid data. But for some reason, when I run this report it doesn't return any errors, however, it doesn't return any records/data either!
Also, I can't debug it for some reason, although I can set breakpoints! This is using VS 2008, but I think reason I can't debug is I believe this is a limited version that just works for SSRS and SSIS.
[Code]...
Could the problem be due to the fact that this web page uses the same SQL connection for both stored procs? The first proc should be returned initially, and the second proc after this screen. So I don't need both stored procs information simultaneously, so I would think I could reuse the same SQL connection.
OK, I found where the problem is located. If I just comment out the Level statement in the Where clause, it does return data. So only thing I changed was that one line in my SQL code and it works. This means missing data must be due to datatype incompatibility, no? What is the problem?
[Code] I can output the above codes, the way I want. but 34 I could not cross the line and then the other page. After 34 lines of each page I want the atlas. 1 through 5 is going to be a between 6 and 8 between the columns, the columns to the right-based format, would like to have the money.

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

View 3 RepliesI have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.
