Populate A Datagridview With Data - Make The Code Shorter?
May 20, 2010
is there a way to make this less in code?Usually when im going to populate a datagridview with data I usually do in this way
[code]...
That how I make things harder although there's a function "DataGridView1.DataSource = myDataTable" and put an sql where selecting those data. I just want to use some other method. so how am I able to add some columns row dynamically and if another column of the database need to get how am I able to add it in that loop is there other way and I want the less code nor the shorter code that you can give to me. I just want to learn and make my code more shorter
I'm currently making an application in vB 2008.The application will be downloaded by several people, which gives me a little problem.Along with the .EXE file there's a folder with 114 images, which are being linked to within the vB [code]...
Im new to vb.net and would like to know the very basics on how a datagridview works? how does it populate data from the database? what process does vb follow to update this datagridview? I'm trying to get my head around the following terms and need some explaining how they work and how they are linked? if possible, is there a link to a diagram that explains this?
I have a form that lists all of the clients in a DataGridView and when I click on a column that is a Link I want the data to populate into the form I use to capture. My problem is that when I click on the link all the TextBoxes on the form are filled correctly but my ComboBoxes are not.[code]
I have form having a button and a gridview. The gridview is ok and generates data. But now, i want to populate only the data when i click on the button specified. Here is my code :
I am working in vb.net and i have a simple requirement. I have added a MDB file to a dataset and it contains 21 tables. I have a datagridview and a combobox on my form. I was able to get the combobox populated with the table names available in the dataset by iterating through dataset.tables. Now i want to add the feature where the user can select the table name from the combo and then it should populate the contents of that table. I tried the following Code
how to populate data into datagridview with combox in it and then save. Using Visual Basic 2005.I have to populate CrewID, CrewName, Address, Position, ReplacementCrew, ReplacementCrewPosition from employees.When the data was populated, I have to click the ReplacementCrew Combox and find the CrewID of employee and display the Position to ReplacementCrewPosition cell. Then save.
I have made DataGridView in the designers and connected an Access database to the datagridvies and the Column headers appear as they should and when I check in preview mode all the fields are correctly populated. However, the DataGrid is not populated in normal mode at all. I have been trying to run the project but nothing is happening. What can I do to populate the field.
I have two data tables. the second related to the first. Using a datagridview for the first table I am able to enter and save data ok. if I run the code twice in a row the data is still there. When I edit the data in the related table in it's own datagirdview the data is there and displays correctly, but on running the code a second time the related data is lost. In both cellendedit events I am using
How could I make the datagridView to unload data from database. I mean, once you make datagridview, it will load data from database so I would like to make it to not load any data. This is for searching purposes where you want to display datagridview look like empty and when user enter information to search in, it then has to display data. Something like Students.datagridView.
I have a dataset along with code for validation. When I use a datagridview and setting the EditMode to OnEnter I get the red exclamations telling me that I have an error when this is needed. This works all good. when I click the save button on the BindingNavigator, the application saves the record even when this validation is showing. How do I filter up this validation code through a datagridview and stop the program saving the data? If you need the code for more information, I will add this to the forum.
I have my mysql query selected fields (item_code, item_name, item quantity, item_selltype, item_selldetail) but some of these fields are variants.
Dim sqlConn As String = ("SELECT item_code, item_name, item_quantity, item_selltype, item_selldetail FROM qa_items") Dim objDataAdapter As New MySqlDataAdapter(sqlConn, objConn)
I have two DataGridViews in one window. The first one displays 2 columns, itemNo and taskWhen I click on a row in this grid, I want to populate the second grid with corresponding material. It is organized so that the itemNo in grid1 is 1, 2, 3, and so on, and so when a row is clicked, I want grid2 to show data that is 1.0, 1.1, 1.2, 2.0, 2.1 and so on. This data is all available in a table that exists within a dataset. However, tableAdapters do not use the .StartsWith function. I am able to get the information from grid1 when it is clicked on using Me.DataGridView1.CurrentRow.Cells(0).Value.ToString but how can I use this to get the data from the table into grid2
I have a DataGridView that I'm trying to populate using a For loop:
Dim serverName As String = SQLServerName + "" + Instance Dim server As Server = New Server(serverName) Dim Datatable1 As New DataTable For Each database As Database In server.Databases Dim row As DataRow = Datatable1.NewRow

The DGV has been designed with the designer (columns, layout etc). Using the above the DGV does not populate. I was using a ListView for this but I need images in a subitem so have switched to using a DGV.
I am working on a project and I want to have a list box with a custom data template populate with user data. My question is, when I click on an item in the list box, how can I tell what item I selected? Basically, if I select "kevin", I want to display his data. If I select Dave, I want to display his data. I do not know how to get the data our after it is bound...
I am attempting to populate a comboboxPlayNotes box within code when a user selects an option. this is the following code:
< Private Sub RadioButtonGeneral_CheckedChanged(ByVal sender As System.Object,
[Code]....
All I get is a combox that has horizontal text, not vertical, like the code writes. I tried it using the "comboboxplaynotes.text" and the same thing happened. Then I put a label out there and the label did exactly what I needed the combobox to do. The words were stacked vertically.
I am using VB.NET 2008 and I have made a connection to an SQL Server database using code.I have managed to populate a datagridview control with the contents of a selected table using a query that I passed in. What I want to do now is set a text box to display a selected field from the query using code.I used to do this using an adodb.recordset in vb6 but I am new to VB.NET
I was just handed a VB.NET prototyping effort, and I'm not very experienced with VB.NET.I had to create a stored procedure which returns a self-referential table in order. Once, I completed that I wanted to get a DataGridView to show the results.
Previously, my team has been doing a lot of this via the GUI designer of VB.NET so I don't have a ton of code to describe, unfortunately.I was trying to follow their pattern which I will briefly describe here:
I have a DataGridView whose DataSource property points to a BindingSource. The BindingSource points to a DataSet. The editor for that DataSet calls a TableAdapter which gets the data from the stored procedure.
I previewed the data for the TableAdapter. The data is there. On frmMain's load the TableAdapter's Fill command is run. Not seeing anything. And my hunch is that this is way too complex a process to be correct. Or maybe not. I did a lot of Google searches before I decided to bother you fine folks.
Using SQL Server 2008 I created a Stored Procedure called MyStoreProc and it runs fine from the Management Tools.
In VB.Net 2008 I created a new dataset and a new TableAdaptor. In this table adapter I created a new Query called FillByGrid and selected the Stored Procedure. Previewed data and it previewed correctly.
On a form I created DataGridView and selected the Table Adapter from the dataset.
I ran the app and no data is shown. Visual Studio autocreated the code below and I changed it to select the the Query I just created:
No data is shown on the grid so I tried the manual approach:
' Create the dataset Dim da As New SqlDataAdapter, ds As New DataSet Dim conn As New SqlConnection
[Code]....
Still no data shown. However stepping through the I can see that the connection is open, and "da.Fill(ds, "tbl1")" takes a little bit of time as it is running the Stored Procedure and ds table has the correct number of rows and columns. Its just not being shown on the datagrid.
Creating another table adapter in the dataset and returning data from a database table using a standard select * from table command display in the datagridview fine.
I am trying to auto populate some fields in my datagridview on my form called frmInfo.
I will try to explain what I need. The main form of my project is called frmEntry. frmEntry is mainly a data entry form only. A binding navigator is present to navigate between different record stored in the database. I want the datagridview on frmInfo to "grab" info present in the text fields of frmEntry.
