I have a form to edit data, with a manually created navigator.Everything works, including the record movement, saving and cancelling changes, etc.My question is...how can I detect if there have been changes to the current record prior to moving to a different one?If the user has made changes to the current record and tries to move to a different record without saving them, I want to prompt him to save.All of the events I've found don't detect a changed record until AFTER the change record has occurred.I assume that typing something in any of the text boxes has to implicitly call the beginedit method.Does that not set a flag or generate an event I can use to set my own flag?
I've looked around here and seen stuff about capturing key down events, looping through the text boxes, etc.Is something this normal really that difficult?If I wanted to write 50 lines of code to do stuff I'd be using C instead of VB.I'm switching from Delphi to VB because Delphi costs $2500.But if I have to spend 5 times as long trying to do standard stuff like this...maybe I need to rethink that choice.
I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for. Is there a way to edit columns and rows manually ?
This is a list of what i want to do : 1. First of all i want to change column captions. because they are like "Fld_name" etc. 2. There is a column that shows date. I want to write a code for it ( convert date type ) 3. I want to add a button at the end of each row and write a code for it ( show detail about that record )
I'm trying to create a page dynamically, but I falling at the first herdle. I have create the below after reading may blogs/post/articles. The problem I have is when I click the first buttons I created nothing happend, if I then click it again it works.Can any one tell me where I'm going wrong?
I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.
I have a form that adds new contacts. New contacts are added by pressing an appropriate button and they appear as an entry in the list on the form. I try now to add an edit button that will edit existing entries.User will select a given entry on the list and press edit button and will be presented with an appropriate form (AddContFrm).Right now it simply adds another entry with the same title. Logic is handled in a class called Contact.vb Here is my code.
Public Class Contact Public Contact As String Public Title As String[code]....
I have an editor created invb.net that creates html files. And when i click the button run , the Internet Explorer opens my file that is inside the Richtextbox.
First of all, I'm quite new to using Visual Basic. This is my first time using a Binding Navigator in a program that I am creating.I have the base of the binding navigator working, data source has been connected (fields etc.). What I need to know now is how I can create a new entry by clicking the '+' button on the navigator, and the new entry appear in the Access database
i have a created a project that enables the user to choose any access database and presents the different tables on a treeview... after that the user is able to drag and drop fields on to another form and automatically controls (text boxes, combo boxes etc.)are created with their respective data bindings... it also creates a binding navigator.... my problem is that i cannot get to add or delete records from the database using the navigator... when i add and try to save it i get an error "Update requires a valid InsertCommand when passed DataRow Collection with new rows" and i get a simiral error message when i try to delete something (plus it deletes everything from the database not only the record chosen).. here is the code i use for the add and delete
Private Sub BindingNavigatorAddNewItem_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BindingNavigatorAddNewItem.Click Try
I created save,delete,next,last buttons.How do i correspond them with the navigator control.This is what i need to do as per the assignment.Both the customer and order tables should have buttons which correspond to the BindingNavigator control. There should be NO BindingNavigator controls. The user should be able to save, delete, go to the first or last record, or go forward or backward one record at a time.
im having a problem populating my data gridview i have use the methond of "add new binding source" on the data sources tab,and drag all the controls on my "Add Form" and the Marriage Table i drag it on my "Print Form".but every time i add record on my add form(using binding navigator) the record i added dont appear on my "Print Form" Marriage
Table :( and when i open the "add form" again the record i added is not saved.
I have two forms with a label on each form. Both labels are bound to the same tbl/fld in a database. When I run program and use binding navigator to scroll thru the data on form 1, I want the form 2 label positioned at the same point when it is shown.
Saving data from textboxes to a dataset Default Values - Binding Navigator But i could not do it or didnot understand how to do it. I have a Binding Navigator created by the wizard, I want to put a value "A" in a Textbox when adding new record (press +). I had tried to use this code in txt_site_GotFocus and BindingNavigatorAddNewItem_Click
I need to insert values into a text-box in a database form, after a 'Add new record' event has been executed
If i code the 'add new' button click event on the binding navigator my code is run first before the record is inserted. This over rights the displayed record then the new record is inserted. Where can i place my code to run after the record has been inserted
I am a newbie using VB.net in VS 2008. I took over a vb.net winform application that has a binding navigator in it. The users wanted to add 2 new fields to the form. I added the new fields to the SQL Server 2005 database. I refreshed the Data Source tab in the project. It recognizes the 2 new fields.
I dragged them onto the form. When I go to add a record through the application, it does NOT save these 2 new fields. I check the properties for these 2 new fields under "Data Bindings" and it shows under the "Text" property the correct Binding Source and column name. I need to store these 2 new fields to the table.
I have a form with a binding navigator on it. It also has a DGV and text boxes bound by the binding navigator. Everything works fine. If you scroll through the row's in the binding navigator it updates the DGV and text boxes at the same time. And also if you click any row in the DGV it automatically updates the text boxes.
Ideally I want to impletment some validation to make sure the users are not only filling in all the required text boxes but also that the data entered is correct.
I have some validation setup in SQL, for example not allowing nulls on particular columns but I really need to be more extensive in the validation than that.
Ideally I need some way of validating the current row selected whether it's an existing row or a new one, before moving to the next row or before save is clicked on the binding navigator. Firstly because the SQL validation messages are not very good, secondly because whilst the data may meet SQL's requirments, it may not be right. For example SQL might accept 12:00 as a time but the program specification requires the user to input within a certain time frame, i.e. 14:00 - 16:00.
Finally, I feel like the validation needs to be handled immediatly on the record that is displayed as ultimatley, the way the form is setup, allows the user to add and amend more than one record at once and if the validation was handled on 4 or 5 different rows then it would bring another problem of having to bring each row up to correct. Therefore I think the best aproach is to handle each row before allowing the user to move onto another one.
I am using VS 2008, VB, and an Access db. I cannot get the save button on the binding navigator to work. I dragged the table from the datasource onto the Windows form creating all of the controls, including the binding navigator. I can add records but I cannot update. The code below is what I have (the commented code is what I have already tried):
I am trying to customize the default binding navigator as i inherit it to my own class and add some buttons to it.every thing gos fine and great as i want it, but the problem is when i change any thing in the AddStandardItems() method class dos not reflect to the existing form which has the same class, i have to remove it from the form and put it again to reflect the changes.This is not good solution, i have more than 30 forms using the same Binding navigator class and it is not possible to remove it form all those forms and put it again.the code for the class is:
Public Class Bind2 Inherits BindingNavigator Private WithEvents DtEditButton As ToolStripItem = Nothing

I use the binding navigator in my application, but when the resolution of the display gets to small and I have to use the scrollbars, then I get a problem. The scrollbars automatically scrolls down below the navigator bar instead of showing it when the window loads. I figured it out using focus or select. it now loads on top,but then I got a second problem.When I press on my tab-control it "autoscrolls" down again and puts the tab-control as the first visible thing on the screen instead of the navigation bar. How can I prevent that?
I am using the BindingNavigator control on my form. I want to use my own buttons instead of "BindingNavigator". I tried double clicking on "Binding NavigatorMoveFirstItem" button to see the code behind it. But nothing is there.What is the code to use the BindingNavigator but on my custom buttons? Actually I want to use my custom buttons but the same code which BindingNavigator uses and then I will delete the BindingNavigator.
I have a form application created with Visual Basic Express Edition 2008 which has a Binding Navigator that navigates through records in a database (Access .mdb file Added with the "Data Sources" wizard). My problem is thus: I need to run code straight after the form controls have been updated with the particular records data. Is there any way of doing this? I'm stuck because all the backend database code is hidden.
looking for simple code for adding, deleting, editing, and updating data using binding navigator in vb 10. first time using, been using vb6 and code is totally different.
I use the Add new button (of the Binding Navigator) to clear the text boxes for a new record, but then have a Update button on the form where I do an Insert query to SQL, which works because if I refresh the table in SQL the new row is there.However when I then use the Binding Navigator 'move previous' button I get an error saying "Column 'AllowOverbook' does not allow nulls. " - now this is a column that is defined in the database to have 'Allow Nulls' = False, but I do not display this field on my form because in this case it is not required.Instead I have it included on my Insert statement and just set it to '0' Also when you look at the table every entry in the AllowOverbook column is '0' and there are no NULLS.
I have a basic data entry form using a binding navigator and a details form. I do the validation in the dataset on the columnchanged and tablenewrow events. These work, and I check the haserrors property before saving, however if the user gets an error, when they get back to the screen, the current item has moved. Ideally, I'd like to have it stay on the item with the error: Private Sub DSHW_FACILITYBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FACILITYBindingNavigatorSaveItem.Click
I am populating a winForm with invoicing information when the user selects the invoice number and clicks a button the information is displayed. How can i use the binding navigator with unbound data.?
Private Sub btnLookupOrder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLookupOrder.Click
I have programmatically set up a Datagrid and binding navigator etc., but I cannot get the movenext, movelast buttons to actually hook up to the Data on the Datagrid.
I have tried to set up an addhandler for the BindingNavigatorMoveLastcontrol, and although I can get the BindingNavigatorMoveLastcontrol to display my messagebox WHICH IT DISPLAYS TWICE FOR SOME REASON I cannot get it to actually move around the Dataset, or any of the other navigation properties for that matter.
