Write Text From A Parent Form To The Active Mdi Child Form VB 2010

Jan 28, 2012

It has to be a simple line of code but I do not know how to construct it. Using VB 2010 Express, I have a MDI parent form and many child forms. I want the parent form to determine what child form is active and load data into the RichTextBox1 on the child form. Each Child form has a RichTextBox1. The parent form gets its data by loading a file.

I am close to a solution but just can't get there. You will see in the code below, if I make a direct reference to a specific child form, it works great. What I want to do is to use the Active Form function to determine which form to write to. I have looked at the MS tutorial which gets me close.

Private
Sub OpenToolStripMenuItem_Click(ByVal sender
As System.Object,

VS 2010 Child Form Tell Parent Form It Is Closing And Send ID?

Apr 2, 2012

I have a parent form that has a list of items and each item has a unique ID. The user can open one or many of the items in a child form (it is set up in a tabbed MDI), but it can only open one instance of each item at a time.

In the parent form, I was going to make a collection (or something like that, maybe there is a better way) to keep track of which items are open in the child forms. I need to know when each child is closed so that it can be removed from the collection and reopened at a later time. I was thinking that when the child form closes, it somehow does something (like raise an event) that tells the parent form to remove the unique ID from the list of current open child forms.

My questions are, is this a good way to do this and I am pretty sure I would use the form closed event in the child form to update that parent form, but as well, I didn't know if this is the best way of handling it.

If raising the event is a good way, are some examples on how to do it out there? I found some for controls, but not while the form is closing/closed.

VS 2010 Parent-Child Form Using DataGrids

Aug 5, 2011

I am trying to create a simple parent-child form in VB2010. I use a datagridview for each table/datasource and each is bound to the parent/child table and each table grid fills correctly. What I want is the parent-child relation to enforce filling the child table with only rows that fulfill the current row on the parent. I have created a DataRelation in the form load, but it will not permit a relation between tables in 2 different datasets. If I attempt to place both tables in a single dataset and define the PK-FK relation in the SQL Server I cannot create 2 separate datagrids from the same dataset.

Refreshing DataGrid On Parent Form After A Child Form Has Updated DB?

Dec 3, 2009

Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?

FORM 1
Private Sub grdList_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdList.DoubleClick
' TODO Ignore Double-Click Event when Right Mouse Button Triggers Event

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.

Updating Parent Form From Dataset After Editing In Child Form?

Aug 24, 2009

I have two forms....Mainform is filled with controls that are databound to a datasource.....then I have a child form that is used to edit data from parent form.......the data that is displayed on the child form uses the Filter() method of the binding source to display data only for the customer selected......

The child form has the standard OK and CANCEL buttons set up as dialog result.......after I edit the content in child form, the changes are displayed on the child form correctly......but when closing the child form and going back to the parent form the changes dont appear there unless I restart the application.....I also tried adding the tableadapter.update/fill method in the 'OK' dialog result event handler and it still doesnt work......

How can I make the changes take effect on the parent form without restarting the application?

Disabling The Parent Form When Child Form Is Open

Jul 18, 2012

disable the parent window form as soon as the user will open the child form....

for eg...consider daniweb...when we click on member login the background form gets grayed out....

Disabling the form is not the option cause it will just disable all the controls of the form....but I need a grayed out screen between the current child form and the parent form....

note - the parent form is not the MDI form...it is just a normal window form and when the child form is open and if the user clicks on the main form without closing the child form then the screen should show some movement...

I tried disabling the form...changing the background of the form to opaque....but could not get through it....

Getting Parent Form's Property Values In A Child Form

Feb 20, 2012

I have a custom form that I use instead of msgbox for a number of reasons. The initial reason was to keep the message centered on it's parent rather than the screen. There are many articles about this but I still have not found an elegant way to get access to the Parent's properties from inside the Child without passing them in (by one way or another).

In the child form the me.parent, me.parentform are not instantiated and apparently can not be used.

The point is to have this form be totally encapsulated with the logic being self contained. This is not an MDI child, and I do not want it to be due to the limitations on MDI children.

My current workaround looks like this I use a ShowMsg Function in my MyMsgBox form which looks like this:

Hiding The Child Form Also Hide The Parent Form?

Aug 16, 2010

I have three forms: A, B and C. Upon a button being clicked, A displays B. Similarly, B displays C. Both using the ShowDialog() method.

However when I use the Hide() method (inside a Button Click event) on form C to close it, form B also closes. Why would this be? As far as I can see, it shouldn't be doing this. I certainly didn't write any code to tell it to do that.

[Code]...

UPDATE: I am an idiot. DialogResult was set to Cancel on the button as I'd copy+pasted it from the existing Close button and not realised that property was set

Take a scenario where I have three forms - B and C. Each of these forms has a text box (could have more than one) There is another form X which has a button. The form X can be called from A, B or C. Now, when I call form X from, say A, form X gets displayed. When I click the button X, a value needs to be written on a textbox of the calling form, i.e. A. Similarly, if B calls X, then on click on the button in X, a value should be written in the textbox of B.
