I have a bound DGV that took a bit of work to get its columns set up. I'd like to show a 1-row version of this identical DGV on a second windows form. Is there a way to programatically place a copy on the second form. I would adjust the height and position of the 1-row version, and create a new binding source on the second form so that I could filter the data.
View 1 RepliesI am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters.
Here is the code that calls the sub form.
Code:
where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.
Here is the code in the sub form.
Code:
Now, I need to refresh this sub form every -- minutes, depending on how the user wants it to be. For this I have given a NumericUpDown control to select the mins. All this works fine. But how do I refresh the dataset and the datagridview?

View 1 RepliesI want to add paging functionality to the datagridview in my windows form. I did a search in google and got some codes too but I am not able to implement in my code as the way I am binding data to gridview is different than the one shown by other codes (that i got from google). I have implemented update and delete also. So I dont want to alter my code but I need to add extra code to implement paging which i don't know.

Turns out this impersonation with .NET's security only allows application-level access. Since the COM object is at the system level, the impersonated user still cannot instantiate it. I figured this out by right-clicking the executable and selecting "Run As...", the program functioned fine. I found out that launches the program with system access (assuming the user you are running it with has those credentials).Now I am in the process of creating an external program that will launch this application using this method.

i was thinking. is it possible to bring the rows that we click at datagridview and bring it into another form. which mean i click on a data that are on the datagridview, then it will pop up a form, inside the form, there will be have the data we have click on the datagridview, and we can edit and save at that form. Can it be done? if yes, how do i gonna bring it over? i only manage to make a windows pop out only. but cant bring the data over.

I have a Windows form which contains a DataGridView within a GroupBox which is within a TabPage which is within a TabControl.The scrollbars property is set to 'Both' so that the user can scroll down to see all available rows in the grid.
I want the Windows Form to initialize to allow the user to see 7 rows but to expanded vertically to the size of 32 rows which is the maximum possible in this application.
Is there a way to size the form dynamically so the Form's Height property can be changed as the DataGridView's rowcount increases?

Wondering if there is a way I can duplicate controls and have them work properly? basically, i have a datagridview with code in it plus buttons that do various things to it etc etc. ideally, i'd like to be able to have two of these datagridviews on show. So, user presses button, second datagridview shows. Note that I don't want them to both display the same data - they should both be independetly editable..
View 3 RepliesI am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
DataGridView1.Columns.Add("CustName", "CustName")
DataGridView1.Columns.Add("Email", "Email")

I want to make a program just like SitckNote in Win7.
When I click "add" button, another form pops up, just same with the current one. How to do that?
I'm building a code editor app in VB.NET (Framework 4.0) and it opens all ".por" files into individual forms consisting of a MenuBar and TextBox (multi-line).Currently I have 20 forms (all duplicates of the first on I designed) and if there are say 4 ".por" files in a directory, the first four will open up while the others hide.
I think it would be far more efficient by coding a new form For each item in form1's ListView...but I want the next so many to be a copy of the first form I designed since I spent a good bit on it.
I want to create an application which can reset itself quickly and easily (without a function to do so). I thought one way to do this is to duplicate the form in it's original form (variables, etc) from the point it first loaded.This is how I thought it could be done:
1. Click button to restart application.
2. Form in use is duplicated by creating a new form with Dim newForm as new Form.
3. New form contains all properties of the original form at the time it was first created.
4. Original form is removed, and new form is used; thereby 'restarting' the application.
I can't find any simple way to do this without making a function which completely resets every variable and object (there's a fair number of them).
I have one form that needs to act as a template for 4 forms, each with its own set of variables.Do I need to set them up like:
Public frmSlot1, frmSlot2, frmSlot3, frmSlot4 As New frmSlotSetup
Or create an array?
Public frmSlot(3) As frmSlotSetup
This problem should be a no-brainer for anyone that programs daily. I haven't worked in VB.NET in many many months, and all of my reference books are at home. I have to modify a program that I wrote a few years back. I need to add a new form to the project that is very similar to a form already in the project. I figured I would start with the existing form and modify it. I still need the existing form in the project, so I made a copy, renamed it to the new name, then copied it back to the folder in which my project resides. Now, I need to be able to add it to the project, but I'm having trouble figuring out how. So far, I have been able to add just the code without the form. If I try to add the form, it wants to create a new form. .
