Forms :: DataRepeater AddNew Causes DrawtItem To Execute Twice?
Jul 19, 2010
I'm using a dataRepeater which is unbound to a list of Objects ( as I need to have two types of object in the dataRepeater).I'm using the following code to populate my dataRepeater
Private Sub loadDeviceDetails(ByVal owner As Mi2.MiOwner)
............
Dim listDevices As New List(Of Object)
Dim c As Integer = 1
[code]....
For some reason the first drawItem runs once, as expected. therafter it runs twice for each new item that is added to the dataRepeater.

I have a checkbox as a control in a datarepeater object. I have an event handler function which handles the checkchanged event for this checkbox and sets the visibility of other fields based on it. However, the problem I am having is that the event handler function is getting fired when I set the datasource for the datarepeater - hence when the data is being populated. So the event handler function ends up trying to set the visibility of a field that has not been created yet and bombs out with a NullReferenceException error. Is there a way to stop this event handler being fired when the datarepeater is being populated? I only want this function to be called if that checkbox is changed by the user after the form has loaded.

This is my first post here so forgive me if I am not following any correct protocols. I am attempting to generate a DataSet and bind it to a datarepeater object. I had been doing this at Design Time and was getting an error message when filling the dataset when the form loaded. So I am basically createing the dataset in my code now when the form loads and binding it to the datarepeater. However, when I attempt to bind the dataset I get a NullReferenceException - even through I know that there are 60 rows of data in the dataset table.

As you can see i have several debug messages in there. I get the error on the last line when setting the datarepeater data source. I try and get data for a specified lot - if it doesn't return any values I create some values in the datatable and add them to the DB. On first load when there is no data this works perfectly. If I then close the form and reload it, it will display fine. However, if I change any of the data (database is updated) and then go back in again, I get the error above.

I'm making a simple game as my first personal Visual Basic program, and I've run into a small problem. I'm trying to make it so when you reach or pass certain amounts of experience, you receive 5 stat points, but the best I've been able to do so far is have the program add the points when you are in a small window of 2 values. This is what I have now:
If Val(lblTtlExp.Text) >= 100 And Val(lblTtlExp.Text) < 110 Then
lblStats.Text = Val(lblStats.Text) + 5
ElseIf Val(lblTtlExp.Text) >= 200 And Val(lblTtlExp.Text) < 210 Then

I am working on a "de-bugging" back-end sorta thingy for my program, and I have a "dll" that executes most of the work for the program. For the ease of tech-support, I plan on trying to impliment a hidden back-door into the engine that is password protected and activated by a key-press. What I want to do is:when the enter key is pressed, have the dll run the sub that is listed in the enter key, for example:
In the dll:
Public Sub msg(ByVal text as string)
MsgBox(text)

I'm trying to access an SSRS url in my app via backgroundworker. I've managed to generate events via the backgroundworker when my app starts. But how do I go to an url without Internet Explorer or any other browser starting up? I want to prime the ssrs server on the start of my application so the first report that is generated with it isn't slow.

I would like that someone show me (with code) how to add a new row to a bindingsource. The same thing that the bindingNavigator does but writting myself the code.The fields of the table appear in the form using TextBox. When I click the button "ADD NEW", the textBox must be cleaned and must be ready to introduce a new row.

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 think I started out with a misunderstanding of what happens with addnew() and canceledit().
I have a strongly typed datasource in memory.
I call bindingsource.AddNew()
Later I find that the record the user was trying to add already exists, so
bindingsource.CancelEdit()
I have not set any properties other than datasource on the bindingsource.
My assumption was that the CancelEdit() would rollback the blank row added by the AddNew(), but I'm getting some odd errors which lead me to believe this is not true.
Could someone verify that CancelEdit() leaves the new row?

I am trying to use a bound datagridview and through the add button on the bindingnavigator adding a new row to the bindingsource and then pass two variables to the datagridview in the new row so they can be associated with the proper ids. I then have a save button for when the end user is done inputting the rest of the data for that record.
The code is below:
Private Sub BindingNavigator1AddItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
AddressesBindingSource.AddNew()
AddressesDataGridView.CurrentRow.Cells("caseNumber").Value = Me.CaseNumberTextBox
AddressesDataGridView.CurrentRow.Cells("interestID").Value = Me.InterestIDTextBox
End Sub
I am attempting to convert and Access CMS to VB and possibly vb.net.

Im using a bindingsource to add new records to my db using bindingsource.addnew()When this is evoked, it seems to automatically increment the recordcount and then blanks out the content of every bound to that tables bindingsource. So that all fields in the new record have to be filled in manually.I would like to be able to pre-fill some of the data in the new record. for instance, when a user adds a new record, have a specific column in the new record automatically populate with the selectedvalue of a combobox.I assume this means I may have to manually code up my own addnew routine, but google has let me down on where to start.

My problem with AddNew. It really is somewhat simple, but I can't figure out the solution. I have a form where I show a list of my rows with a given a table. The user can then select a row and press clone, which then will try to make a copy of that row.
Here is a snippet:
Dim rowToCopy As cmaDBDataSet.cmaPropertyRecRow
Dim originalID, newID As Integer
rowToCopy = CType(CType(Me.CmaPropertyRecBindingSource.Current, DataRowView).Row, cmaDBDataSet.cmaPropertyRecRow)
originalID = rowToCopy.id ' id of row to be copied
[CODE]...
.... and continue to copy the rest of the data to the newrow...One of the items in the row is obviously a primary key called id. I can not copy this data since I am creating a new row. My problem is, how do I set that value!? or atleast retrieve the value for the newly added table. I need that value so that I can call another form to actually allow the user to modify this newly cloned data. I tried using EndEdit, UpdateAll, no worky. THen I thought I could assume that the newly added row would go at the end of the table so I used MovedLast then got the currentRow id from there... That worked well until we did some deletes within the table.

in my form_load sub i added a line to enter a new row when the form is loaded by using me.bindingsource.AddNew()Is there anyway i could tell it to only add a new line only if the rows are empty, the table does have a primary key column where its seed is 8000 i dont know if this would make a difference to how you would make it work

Is it possible to get value of a text box, say at row 4 of a datarepeater. I did it by moving control to it, but that does not work the way I want. I used code DataRepeater1.currentIndex=5, and then picked the value. Is there any possibility of getting the value without moving control to this row. I mean the way we get value from datagridview (vrName=datagridview1.item(1,1).value)

My database is an Access file. In my Data Sources Window, I selected the Attachment column for my file as a picturebox. I dragged it onto the DataRepeater, along with a Label. The label's properties are working correctly, but the image does not show. Is this not the correct way to have an image on the DataRepeater control? There is no code for this since it was just a drag-n-drop.

I am looking for help with the DataRepeater in VB.Net PowerPack 3. This is Windows development were talking about not ASP.Net. I am able to set it up for a single dataset but I actually want to nest another DataRepeater inside of it. Anyone have experience with that? Is is possible? I've done it with ASP.Net but I realize were talking two different animals here.In my testing the top level repeater seems to populate fields but the nested repeater shows up empty. Nothing in it. My data tier is using LINQ to SQL.[URL]..
