Datagrid with results form sql query
View 10 RepliesI've got a button that sends an sql query to the database it works but i don't know how to fill the datagrid with the results of that query
View 1 RepliesI 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"

need a quick reply looking for code that will filter my datagrid with all the results between 2 dates in 2 datatimepickers. My table is not bound to the database. I'm looking for code that will work when the search button is pressed.
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. What I want to do is display all the results in a datagrid.Here is the code I have now.
Imports System.Xml
Public Class search
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim xmlFile As XmlReader

Is there a way to modify this code to show multiple results in a datagrid? For example, you have a locomotive and rolling stock named Santa Fe. I want to return all results for Santa Fe.
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?

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code
Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.
I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
what are the differences between the WPF Datagrid included in the .NET Framework 4.0 versus the Datagrid included in the out-of-band WPF Toolkit? I understand that the toolkit version was released first, and targets the .NET Framework 3.5 SP1.
I needed a WPF datagrid quick and have utilized the toolkit version in my applications. I'm considering moving the application to .NET 4.0 and am wondering what the pros/cons will be in changing out my existing datagrids for the new ones.
I have one data grid which contains a column which contains long string values. When I edit it, the text box which appears is very small. I want to increase the length of text box.
View 2 RepliesI am just trying to put an item into a datagrid from another datagrid.
So I got code like this which takes the right item but puts it into the wrong place. It is suppose to put it into Rows(0).Cells.Item(3) but it puts it into item(2) as it caunts from 0 to 3. If i try to put it into Rows(0).Cells.Item(4) I get an error - indexOutofRange.
DataGridCLI.Rows(0).Cells.Item(3).Value = datagridorder.Rows(0).Cells.Item(2).Value
I have created a program that randomly produces simple maths questions and saves them to a SQL Server (SQL Server 2008 R2). The code looks fine and works if I step through the program. Each pass it creates a random question answer and saves them to the database. However, if I run it (Debug/Release), the program produces a question and answer but repeats it in the database.

how to get raw xml results from a web service.

How can i turn in the results to raw xml?
I am having a SP run in my VB application every 10 seconds to check for any new rows that have been inserted to the database since the last check. What is the best way to do this? Most likely it will be 0 or 1 rows, but I am afraid at random times it maybe more than 1 and so I thought I would fill it in a DataSet, but I came in here to see if there are any other better ways. If dataset is the best way, how do I do a For Each Row in the dataset to process some VB code for each row?
