So I am adding a new row to the datatable, then update but if I query the datatable it is not there. What am I doing wrong?

I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.
Friend WithEvents Panel1 As System.Windows.Forms.Panel

View 11 RepliesI have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?

I have added a button in datarepeater. If clicked once, it executes code and Button.text should change to Yes. Clicked again, it executes the opposite code and button.text should change to No. Codes are being executed (I am using flag variable) but Button.text is not changing.
How to change this text. I am simply trying Button.text="Yes" but probably I need to give some reference of the row no. too. How to do it?
I am trying to create a Form that can be filled out in it's entirety without having to bring up other forms. It is considered in access to be a subform. I have one table that includes Injuries and each injury has a specific ID well I have all the information that goes with it updating, except for the "many-to-many relationships"...I one want injury to have more than one treatment type, the problem occurs when I drag the injury table over from my dataset it automatically creates a binding source for it, which only controls the data inside that table. It does not control the data that is related to it such as "treatment type" "body part injured" . There must be a way to have a single Inj

I understand the page lifecycle and how i need to add the dynamic controls on page_init if I want to take advantage of viewstate. Also I know that I should try to avoid dynamic controls when possible. The dynamic controls are created depending on an object that is created from custom event arguments sent from a custom treeview. Problem is I need viewstate so I need to create them in page_init but I don't have the event args to create the object that tell me what controls to add until later in the lifecycle.
Private Function GetEventArgs() As npTreeViewEventArgs
Dim control As Control = Nothing
Dim e As npTreeViewEventArgs = Nothing
[code]....
I use this in page_init to create my object and controls.

View 3 RepliesI have a DataGridView which I AllowUserToAddRows behavior enabled. I want to be able to force that only one row be added at time, then if the user clicks the save button the row is inserted into the database, and then another row may be added if the insert was successful.
The reason I want to do this is to get the last inserted id and insert that information into another table.
I have a 'user' table, a 'phone number' table and a 'user to phone number map' table. The phone number table stores only unique phone numbers. This way I can take a look at a phone number and see who is using it easily. It is also easy to check if a phone number exists when the user is edited. The question is how I should be checking to see if the phone number should be added to the map. I could loop over the loaded mapped users and check each id. There must be a method that I can use to check like EdmUser.phone_number_map.contains(PhoneNumber). However I cant find anything like this.
