I have a Datagridview collections embedded in several Tabpages of a TabControl. I want to use to control Button to import data to the datagridview. Data is different for different datagridview. I want to know which DataGridView is currently shown (on the top) when I click the control button so that I can send corresponding data to it. What shall I do?
I am trying to create a datatable to be shown in a datagridview.. i have created a DataGridViewComboBoxColumn that has a data source and now i wanted to create a DataGridViewTextBoxColumn but i dont know how to make it take its data from a column in a table.. i did it with the comboboxcolumn but i coudnt do it with the textboxcolumn..
I have an application that uses DataGridView in two different locations. In one location, the DataGridView shows everything fine. In the other location, whenever the form containing the DataGridView is initially loaded, only about half of the visible portion of the DataGridView is actually drawn; through the rest of the DataGridView, the underlying windows graphics can be seen; if you scroll down through the rest of the data, you get a choppy view of what corresponds to the bottom row being scrolled upward through each scrolled row. The only ways to get the DataGridView to show the correct values are either to select a cell, forcing that particular cell to redraw; or to invalidate an area of the window, causing that area to redraw (which it does do correctly).
I've compared how each of these DataGridViews were set up: For the one that works fine, the DataGridView is statically bound to a BindingSource, which is statically bound to a DataSet; the one that has the draw problem is statically bound to a Binding Source that is dynamically bound to a DataTable during the creation of the form.
What could be causing my DataGridView to not display correctly?
I have a MainForm which contain SecondaryForm as a control of the MainForm.SecondaryForm contains DataGridView which loads data from sql server and I add a collumn named SUM that SUMs all the values of the same row. This is provided within the LOAD event of the SecondaryForm.When SecondaryForm.Load events finishes, the program goes back to MainForm right after the line "SecondaryForm.Show" and here the values of the column SUM disappear.When i write those values runtime, they never disappear.
after i drag the datagrid view from the data source windows the group of controls appear in my form does not include a binding navigator, i also dont see it in the component area.
but when i try the example from northwind database after i drag datagried view it already have a binding navigator. why my own project dont?
EDIT: im able to figure out about this 1st question, just a little bit of exploration , i just add the navigator control from the control toolbox. then set the binding source. ^^,
question 2: when the binding navigator is now available.
when the navigator is already now in the form i will set the visible property = FALSE.
i will make a control button that will serve as "Save and Addnewrecord" that will save the data (from the text box )and save it to the table and add new record read to accept new data.
I have the following code to resize the datagridview but the vertical and horizontal scroll bar are not shown when there are colunns and rows exceed the width and height of datagridview objects.Bascially the following code is similar to dock to the botton, the only difference is docking to the botton change the Y position of datagridview and fill the botton section whereas my code fix the Y position of datagirdview and fill the bottom.[code]I have tried with the dg.ScrollBars = ScrollBars.Both but it it is not working as well..May i know how to get both scroll bars working.
I have a form consisting of datagridview and two buttons of update and load all.. I have used fillby method to obtain data from database. The query seems to be working fine, except that the data is not shown in the gridview. As in, for the qeury, if the returned rows are 2, it will show 3 rows in the gridview, but all empty.
I am busy with trying to convert data from an application so that it can be shown in HTML form via websites. I need to make a tree wherein I have 3 main categories each with their own sub-categories. These are the categories/sub-categories.
I have been working on a much larger project and came to a point where I decided threading should be used.It seems in previous version of .Net, a background worker was able to update controls that were were not created on that thread. Now, it doesn't seem to be the case.I basically just began a new small project to try and teach myself the basics.Form1 Consists of A listbox, A progress bar, a label and two buttons, one to start and one to cancel.
imports system.threading private sub btngo(byval sender as system.object, byval e as system.eventargs) handles btngo.click pbprogress.minimum = 0[code=....
This code appears to be updating the listbox.I can see the vertical scrollbar getting smaller, but no data is shown in the listbox. The progressbar is also updating properly while that is working, indicating proper background operation.But what it's not doing is this:
1. Label is not updating percentage
2. The form is not free to be used by the user (me)
I have tried this but this is not working.[code]Here i need to take the data from exds to text boxes. As when we click on combobox we need to show data according to that party in all text box's.[code]
facing the same problem.I have tried this but this is not working.

I want to see if anyone has used one table that has a primary key (not displayed) in the DataGridView. Then use a text box on the same form to call and group what if viewed in the DataGridView table. I want to group the displayed data of the DataGridView by the primary key of both tables.
I have two data tables. the second related to the first. Using a datagridview for the first table I am able to enter and save data ok. if I run the code twice in a row the data is still there. When I edit the data in the related table in it's own datagirdview the data is there and displays correctly, but on running the code a second time the related data is lost. In both cellendedit events I am using

I am trying to click on certain rows in a datagridview and have the information in the rows sent to a textbox. It does not append each row to the textbox though, which is what I want it to do. it just replaces it with the row I click on. What's wrong with my code. I have tried cell click too.

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
