Have A Form Consisting Of Datagridview And Two Buttons Of Update And Load All?
Oct 7, 2011
I have a form consisting of datagridview and two buttons of update and load all.. I have used fillby method to obtain data from database. The query seems to be working fine, except that the data is not shown in the gridview.As in, for the qeury, if the returned rows are 2, it will show 3 rows in the gridview, but all empty.
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'm still working on making my button project and I've came across a new problem.
I want to create buttons based off the amount of lines in a text file which will be easy if I can get this to work. This is my test code before I implement it into the real program:
I have a picture box in which I type some letter on capturing keystrokes.The problem is that at Form Load, the focus is on the buttons available on the form. How can I keep the focus on my Picture Box at form load?
I want to make an application that shows the calculation sequence consisting of 3 form.1 is an input form,form 2-step sequence of calculations can be saved as pdf,he calculation
I'm creating part of a program which calculates vacation hours multiplied by accrual rate. As of right now all parts of the form are functioning and saving/retrieving data from a csv text file. My problem is that I'd like to bring the process out of a button.click event and into Form_Load. Currently when I click a listview item (lvwData.SelectedItems) it populates a textbox (txtAvail), then recalculates the textbox value based off my formula (hours) and updates the listview's 4th column item. To update each column daily, I currently have to click each row, then my button, then move onto the next item. I'm looking for a way to grab the 4th column, recalculate it and update the listview without having to select each row.
I have a program, that on form load, updates a value. The problem is, that it doesn't work!
my Imports MySql.Data.MySqlClient Public Class Form1 Dim MysqlConn As MySqlConnection Dim UserCommand As New MySqlCommand Dim SQL As String [Code] .....
And the problem is that it doesn't update the points. I set the points to 10 via PHPmyadmin, and run the program, but when i go back to PHPmyadmin, its still 10.
I have a project in which i have a form in which there is add button to add pages. In form load the last entered page populates all the fields. Now thing is if user edits the values in controls it has to update the db with those fields and if the page doesn't exist in db it has to insert.
Here is my code Private Sub inserting() Dim cn As New OleDb.OleDbConnection 'Dim selectquery As String cn.ConnectionString = "" Dim cmd As New OleDb.OleDbCommand [Code] .....
I initialized a global variable x and set its value to 0 in page load and in add button click to 1. Depending on x value it either inserts or updates the db in form closing and add button click. Now whats happening is If the user clicks on add button the page increments but if user doen;t enter any values and tries to close the empty form, value of x =1 and it tries to insert but as there are blank fields cmd.executenonquery throws an error.
"The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data."
What should I do so that it doesn't give an error. I am using access db.I even checked in db Except for primary key(pageno) all other fields have "allow zero length" as YES & "required" to NO.
I have 7 Windows forms.The order of the forms is defined within a configuration file.I want to place buttons on each form that will show the next available options.The Next button will move the next form in the list.The Back button will move to the previous form in the list. The Finish button will execute the final piece of code.The Cancel button will exit the application.If the user is on the first form, then there is no Back button.If the user is on the last form, then there is no Next button, but there is a Finish button.
I have a dialog that containers a DataGridView, this dialog is opened from a parent Form. I would like the DataGridView to have focus as soon as the form is opened, so on pressing the down key would enable you to scroll down through the rows straight away. I have tried setting the tab index so that the DataGridView is the first selected item in the form. I have also tried calling the DataGridView.Focus() method in both the dialog constructor and the Form_Load event. I have also tried setting the
I have a access table column ("d") and rows with value Datetime. How can I ..... when form load make the datetime now ..visible. What is the code for making the rows with datetime value now start with index 0.
I wanted to select the row the user was last working on in the datagridview. So I created a setting to contain the row index. But then I had trouble using the form load event to select that row in my datagridview. It would always select the first row. I then moved the code into the DataBindingComplete event and it worked like a charm Example:
Private Sub dgvTaskList_DataBindingComplete(sender As Object, e As System.Windows.Forms.DataGridViewBindingCompleteEventArgs) Handles dgvTaskList.DataBindingComplete
[code]....
PS, if you want to select the full row, make sure the DataGridView Selection Mode property is set to FullRowSelect.

at the moment i can change the datagridview combobox cell style using the cellvaluechanged event handler using the following code: Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged If e.RowIndex <> Column1.Index Then
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]

I'm using a dialog form with two buttons and two Radio buttons.I'm oppening this Dialog when a button is clicked on the parent form.My situattion is when the Dialog opens the code in the button event continues to execute, but I only want it to continue to execute only after a button from the dialog form have been clicked
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click If multipleEXT = 2 Then Extension.Show()
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 have been playing around with Visual Basic for about a week now. I created a program that I use at work basically just to organize my day.
The program consists of buttons that link to programs and spreadsheets that I use often, as well as a checklist of tasks I've completed and text boxes that I use for reminders. Other buttons affect GroupBox texts and Label texts.
What I'd like to know is how I can implement a Save and Load button? I'd the current state of the program to be saved so it can be loaded in the event that I have to shut the program down. (Check boxes checked, Text in Text boxes, Labels, etc...)
I've been looking online for HOURS and I've messed around with the SaveSettings feature... nothing seems to work.
When you complete various feats in my program, on a form called "User Details" there is a label with the text that says "Complete" only when you have completed a particular game. There is a save button, and a load button, all on different forms. How could I make a save and load feature? One that saves the fact you've completed certain games - and then when you press load after exiting and reentering the program, the Complete text will reappear.
My VB application is behaving strangley. I have form with fairly large number of controls. I am using case against radio buttons. after curtain number of buttons, it stops responding to more radio buttons.
Then I tried to split controls in to 2 form but now my form.showdialog() too now working properly. It takes new from names but show the old form when running.
I put in a picture box and then it starts with image1 and when the box is clicked the image changes to image2, I want to make it so that when the box is clicked again image2 changes back to image1. [url]...?[code]...
I'm making a text Editor, that can load unrelated code then edit it graphically using buttons.So far my problem is with replace, I'm probably not using the right context some times it works, most times it does not.
I need to set up a list consisting of arrays of two elements. Simple, right?
Like: (code snippet):
Dim strDataPoint(1) As String '2-element array Dim lBiasCurve As New List(Of strDataPoint) 'list of 2-element arrays Dim lPwrCurve As New List(Of strDataPoint) 'another list of 2-element arrays
But this gives me an error msg on 2nd and 3rd line: type strDataPoint is not defined....
I have been on a database project for a while now. I wanted to be able to make changes to my database using the update command of a Datagridview control.However, I have been faced with a series of unsuccessful outcomes.I want to do this how do I go about it?
