VS 2005 CheckBox - Load The Data To Form Datagridview
Mar 10, 2010
regarding the DataGridView Checkbox.. I have two Forms, The 1st one has a datagridview..but in order to load the data to form1 datagridview, i need to open another form w/c also has a datagridview w/checkboxes on it.. I need to select a data in the form2 datagridview w/the use of checkbox..when i select an item..then press the ok button, the checked checkbox with the info corresponds to the data i selected will appear in the form1 datagridview. I have done this and works fine, but when i select two data or when i checked two items on the form2 datagridview.. only one info is added on the form1 datagridview.. here is my
When the form loads I want to fill the combobox with the data present in the database. So I did the below
Private Sub BindCombo() con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersGautamDocumentsVisual Studio 2005ProjectsF1pracF1pracBank_Account.mdb") con.Open() cmd = New OleDbCommand("Select * from BankAccount", con) [Code] .....
Doing this code the data is added up in the combobox dropdown list. But when I am selecting a data from the combobox dropdown list,the all the corresponding data of the other combobox also get filled automatically. I don't want to let the other combobox filled with their data automatically....
Form2 Objects Form2 = frmUpdate Button = btnSubmit 15 textBoxes = you can see its name in the code below and all of them are data binded
MainAppForm Code Pass the selectedrow data to form2 (frmUpdate)
Private Sub btnUpdateDouble_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click If DGVMain.SelectedRows.Count = 1 Then
Catch ex As Exception System.Windows.Forms.MessageBox.Show(ex.Message) End Try ElseIf DGVMain.SelectedRows.Count = 0 Then MsgBox("Please select one item to update!", MsgBoxStyle.Information, "Update") Else MsgBox("Updating multiple Items is not allowed!", MsgBoxStyle.Information, "Update") End If
End Sub
Form2 Code I want to update the data by this code, but it refresh only the data in Form1
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Me.Validate() Me.SparePartsBindingSource.EndEdit() Me.SparePartsTableAdapter.Update(Me.InventoryDBDataSet.SpareParts) 'Refresh MainAppForm.SparePartsTableAdapter.Fill(MainAppForm.InventoryDBDataSet.SpareParts) End Sub
No problem in updating the data if I put the code below in Form2 load event
I have searched the web and this site for an answer but have not been able to solve this problem.I am not able to place a flashing cursor in a specified cell of a data bound DataGridView on Form_Load.My test project consists of a single Visual Basic 2008 form with a database created in Microsoft SQL Express 2005 using the Add New Data Source in the Data Sources window.The database has one table consisting of 2 columns.Column 1 being the primary key with Identity Specification set to On.The second column is a VarChar50.The DataGridView was placed on the form by dragging it from the Data Sources window thereby creating the Binding Navigator and the Private_Sub Form_Load code.I have added the code that should put the cursor where I want it.[code]
Imports System.Data Imports System.Data.OleDb Public Class Form1 Dim con As OleDbConnection Dim cmd As OleDbCommand
[CODE]...............
The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
I am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
i have 5 checkboxes in webform and textbox1... when i search the record using the date specified in textbox1 when i enter 11-Dec-2010 in Textbox1 and click on submit button then checkbox1, checkbox2, and checkbox3 will be disabled and unchecked .....
I am trying to add a checkbox column to a DataGridView in a simple window forms application.
I am pulling back some data from a database using ADO.NET, putting into a datatable, and then setting the datagridview datasource to the datatable. I then want to add a checkbox column as the second column. So far I have this code that seems to work:
' Code here to connect to database Dim da As New SqlDataAdapter(cmd) Dim dt As New DataTable
[Code].....
This code 'works' and I get MyDataGridView to show the data with the checkbox column in the correct position in the table.
However, for some reason, I cannot check any of the check boxes in the DataGridView? I have tried lots of things (e.g.altering the readonly state of the column) but cannot get it to work.
i'm making a utility in which i'm loading 100,000 records again and again, problem is that it takes much time to load records in datagridview every time.
i've used data set and data reader both but same result. if i use paging then there's will be a problem of search a record on keyup event.
I have create setup for my project, when i tried to open the form which contain datagridview on it. It give me this error. Here is the attachment screen shot of the error.How to solve this error.
I have a checkbox in my application,when the checkbox is checked then i want to fetch the data from the database and add it to the dropdownlist of the combobox.Again when the checkbox is unchecked then i want to ramove all the data from the dropdownlist of the combobox.
I did this
Private Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged If CheckBox1.Checked = True Then con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=Etech.mdb")
[CODE]...
When the checkbox is checked then the data is added from the database to the dropdownlist of the combobox but when i uncheck it then the data is not removed from the dropdownlist of the combobox. In the above code i think i need to add an else condition to remove the data from the dropdownlist of the combobox and make it empty when the checkbox is unchecked.......but i cant give the proper else condition in the above code.
aside from the difference mentioned below, what are other difference the two events might have and how will affect the application as a whole? What is more preferred to use and why?
Form Load: *Do stuff* Form shows up on monitor Form Shown: Form shows up on monitor *Do stuff*
My code is working fine I just need a way to reset the DataAdapter1 into 0 (like reset) So if the user hit the button search 2 times to shows up only 1 time the elements of database "product".. If i used the code below and hit 2 times the button the DataGridView show 10 product for examplat the first time and +10 for the second, a total of 20 products, even if I search then edit a product and search again it's fixed the previous table and prints again 2 times the table....
I have a DataGridViewCheckBoxColumn who's column name is "booReadyToReport want to hide all the checkboxes in this column if "bintAnalyteCodeID" doesn't equal the selected value in a combobox on my form. ut I run this bit of code the DataGridView DataError event fires currently, have nothing in the event except an comment. he code seems to work, but I'm new to VB.NET and I'm wondering if this is the correct way to handle thishould I use the CellPainting event?
highlight rows with RBF3 For Each dr As DataGridViewRow In Me.dgvCalculatedResults.Rows f dr.Cells("bintAnalyteCodeID").Value = Me.cbxAnalyte.SelectedValue Then
i have code to load data from database to DataGridView.

I am loading data from query into a dataadapter and then into a dataset.the datadridview datasource is the set to the dataset.but it takes too long to load the data into the datagridview.
I create more then 10 columns in Access 2010 and I have a lot of rows. I write code already to load data to my datagridview, but I want to know to how to load data with progressbar untill finish. *If loading data does not finish the progressbar does not finish,too.
I have two form in my application form1 and form2. Here, i want to show the form2 from form1 by using a button. And i want to reverse back to my form1 from form2 using same technique. But i want to close form1 (Not visible=false or hide) after loading form2 and same thing in reverse back also.

I was wondering if there is any way to load data from excel sheet into a datagridview in VB2008 dynamically. I have looked at few data connection codes but all of them involve the excel sheet and thw workbook name. Is there anyway that I enter the excel sheet name in a inputbox and the data from excel loads into datagridview without hardcoding the sheet name. I know data can be imported using the below code, here the programmer has to mention the excel workbook name, path and sheet name. [code]I am developing a program to perform some calculations and my data is in a number of excel workbooks and worksheets. I need to be able to bring the data from these excel sheets into the datagridview to perform calculations. So I was thinking if I could mention the excel sheet name in the GUI and then accordingly the data from that particular sheet would be loaded into the datagridview to perform calculations.
So i want to display this data in datagried view. I must display the number beside T to T column, the number beside C to C column and so on. It should only display number in the respective column. It should not display the T,C and so on.
I have the option to save the contents of the listview that was saved into text file.now i would like to load the text file into datagridview in vb.net but i have no idea how to do it as this is my first time in doing it and i had googled around but couldn't find the information i needed.
I was doing this [URL].. and i got the map to come up when i saved the notepad doc as a .HTML.I want it to come up on VB Form though, is it possible and how hard it would it be?
I have set my forms font as "Segoe UI, 14.25pt" and have just placed an single label on the form.
Upon placing the label by default it gets the forms font i.e Segoe UI, 14.25pt
i have placed the following code on the labels textchange event
Private Sub Label1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.TextChanged Dim f As New Font(Me.Label1.Font, FontStyle.Italic) Label1.Font = f MessageBox.Show(Label1.Font.Name) End Sub
Now when the form is loaded , i get a message box showing the labels font name as "Microsoft Sans Serif"
The labels font size also changes to 8 but it is italic.
Why is this happening? And why does the textchange event occur on the form load?
