Created Datagridview Control Used To Display The Data Using Sqldatareader?
Apr 15, 2010
I am having problem with datagridview. Actually I have created datagridview control used to display the data using sqldatareader. My problem is that How can I fill the data in textbox control when user selects the row in datagridview using coding. For e.g. my form is having a) Datagridview and displaying values of columns: Name, Address, City, State etc and textboxes: txt1, txt2, txt3, txt4. Now if the user selects any row from datagridview the selected value of Name is filled with txt1, address is with txt2, city with txt3, state with txt4. I am directly dealing with database with using DataAdapter.

I have a DataGridView that I'd like to load with data that I'm retrieving from a SQLDataReader running in a background worker as the data comes in (it's a query that takes a long time). My goal is for the user experience to be similar to searching for a file in Windows where the results appear in the list as they come in and you can still interact with the window.
I have it working with a background worker and data reader and I'm trying to add the row from the SQLDataReader.Read through using the BackgroundWorker.ReportProgress method. Everything technically works but the flicker is crazy and the form is unusable (probably not because the GUI thread is blocked but just because there's so much going on...) How do I make loading the datagridview "smooth"?

I am having trouble in allowing the user to select the row in the datagridview.
I managed to include the checkbox column in the datagridview but i do not know how to wrte the code such that when the user wants to update or edit the data in the checked row, he just have to check the affected rows checkbox, can be one or many, and then click on ok button, which will then lead him to the data updater form, allowing him to update the data.
Currently i have the below code which can populate the checkboxclumn only.
dbProvider = "PROVIDER=MICROSOFT.Jet.OLEDB.4.0;"
dbSource = "Data Source = '" & Form1.TextBox8.Text & "'"
con.ConnectionString = dbProvider & dbSource

I've been asked by a local window cleaner to design a small utility that can display a grid of customer data, sort them, and then export it out as a formatted .txt or rtf file.

I created Dataentry forms. In the form there are so many controls like DropDowns and textboxes. I am using Access database. Now I enterd the few records into the controls, and these records are saved into the Database. But now if i enter the any data which i recently saved in the database to the textbox or any other control then the remaining controls should be display the related data.
For example i have 4 controls in my form one is dropdown and 3 are textboxes. If i select the data in the dropdown then the remaining 3 textboxes shows the related data. How can i dispaly the corresponding data to the other controls?

This is incredibly urgent, I need to present this application in 3 and a half hours.My application checks against a data source to see if a value exists in the database and changes values depending on whether or not the value in question was found.The problem is that I've run the sql query with the value in question in SSMS and no rows were returned, and yet, my DataReader says it has rows.[code]val will only be returned True if the NumberToCheck (in this example 3235553469) exists in the database.Having copied the value of NumberToCheck into SSMS and testing the query there, I can verify that the query does work as expected.No, I can't populate a DataSet because of the volume of information in the table (+/- 9.5m rows). Even with the 'WHERE' filter, the query is too heavy on resources and eventually ends in an OutOfMemory Exception which is why I went with a DataReader.

I am running queries using sqlcommand and am trying to get the results from sqldatareader into a dataset table. It works fine when loading the datareader data as a row into the dataset table and writes it to a crystal report.I would like to have depending on the query results have the data in the appropriate columns and it only happens if the results are from all fields.
Dim CommandObj2 As New SqlCommand(sql, cnn)
sqldr = CommandObj2.ExecuteReader()
While sqldr.Read()
Dim dataRow As DataRow = ds.Tables("NTable").NewRow()
[code]....
MsgBox(ds.NTable.Rows.Count, MsgBoxStyle.OkOnly, "Records Count")My dataset and table have the same name, NTable. Question again is how to populate the dataset columns accordingly.

I'm stuck on a problem that I haven't been able solve. I'm making a visual basic program that communicates with an SQL-database. The problem emerged when I tried to retrieve data from the database with the help of SqlDataReader and save data from every row to a list (Customer) with the help of Add-method. It turned out that eventually the list had correct number of objects, but the information was the very same in each object of the list.

I'm using Visual Basic 2008 in Windows 7. I've added a datasource to my project and dragged an element, a sort query, from Data Sources onto my form. It automatically created a DataViewGrid and placed this statement in my form load event: Me.SortBillsTableAdapter.Fill(Me.DoBills_2009DataS et.sortBills). The datagrid view shows all the fields/columns. When I preview the data element from right clicking the element, selecting Preview Data, and click Preview in the Preview Data dialog box, the data appears. But it does not appear when I run the app. The datagridview is empty. What am I missing to get the data to display in the grid at run time? I did notice that in the properties for the dataviewgrid the databindings property is empty. Is that right or am I supposed to do something there?

I am wondering how one would go about using the graph control to display a bar graph that shows trends from my database.They are rather easy trends. I am building an industrial issue tracker and I would like for it to show how many issues were submitted each month for the last 6 months and also how many issues in the last month were of certain types that are categorized in my database.
