Update Open Child Mdi Form Textbox From Parent Form?

Feb 3, 2012

I have a date selector on mdi parent that updates a property when date is changed. When I open a child form, it grabs the property just fine. However if I change the date again after the child is open the date does not change on the child unless I close and reopen the form as expected. What would be the best way to automatically update all open child forms when the date is changed on the parent at anytime? running a timer to parse the date property is impractical.

Form Load - Insert Or Update Data

Nov 10, 2009

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.

How To Load Data From Form1 Datagridview To Another Form & Update

Jan 30, 2011

All I want is to update the selected row data in form1 to another form2



Form1 Objects
Form1 = MainAppForm
DataGridView = DGVMain <= binded
Button = btnUpdate

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

Try
frmUpdate.ItemIDTextBox.Text = DGVMain.CurrentRow.Cells(0).Value.ToString()
frmUpdate.PartTypeTextBox.Text = DGVMain.CurrentRow.Cells(1).Value.ToString()
frmUpdate.PartNameValueTextBox.Text = DGVMain.CurrentRow.Cells(2).Value.ToString()
frmUpdate.PackageTypeTextBox.Text = DGVMain.CurrentRow.Cells(3).Value.ToString()
frmUpdate.QuantityTextBox.Text = DGVMain.CurrentRow.Cells(4).Value.ToString()
frmUpdate.UnitTextBox.Text = DGVMain.CurrentRow.Cells(5).Value.ToString()
frmUpdate.DescriptionTextBox.Text = DGVMain.CurrentRow.Cells(6).Value.ToString()
frmUpdate.LocationTextBox.Text = DGVMain.CurrentRow.Cells(7).Value.ToString()
frmUpdate.ProjectBoardTextBox.Text = DGVMain.CurrentRow.Cells(8).Value.ToString()
frmUpdate.CommentsTextBox.Text = DGVMain.CurrentRow.Cells(9).Value.ToString()
frmUpdate.OrderCodeTextBox.Text = DGVMain.CurrentRow.Cells(10).Value.ToString()
frmUpdate.CurrencyTextBox.Text = DGVMain.CurrentRow.Cells(11).Value.ToString()
frmUpdate.UnitPriceTextBox.Text = DGVMain.CurrentRow.Cells(12).Value.ToString()
frmUpdate.SupplierTextBox.Text = DGVMain.CurrentRow.Cells(13).Value.ToString()
frmUpdate.ManufacturerTextBox.Text = DGVMain.CurrentRow.Cells(14).Value.ToString()

frmUpdate.Show()

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

Me.SparePartsTableAdapter.Fill(InventoryDBDataSet.SpareParts)



but the problem is, it will refresh all the data in the Form2, and my code in Form1 becomes useless.




Thanks in advance!

Mar 11, 2009

I am converting some VB6 code which passed an unknown form object to a class, which then used the passed form object to reference the calling form and direct the data from the class as follows:
The Called Class in the class clsGetRecord
Public Function Execute(ByRef FRMForm as form) as booleanFRMForm.List1.Additem(SomeData)....Execute = SomeBool End Function
The clsGetRecord is used by many different forms which receive data all have objects called List1 as: The Calling Form for the form
frmThisFormPrivate function() as booleanDim objRecord as new clsGetRecordbRet = objRecord.Execute(frmThisForm)
The passed form object which will receive dataEnd function. Is there any simple way to do this since the calling form object is unknown at design time?
