I have a DataGridView on my form and I'm wanting to override the 'Add New Record' button on the DataGridView controls, and display my own 'Add record' form. The problem is, when I do so, I no longer get the Auto-increment functionality of my primary key field (as i would If i used the default functionality of that particular button).

so ai have created this new TableADAPTER in my dataset, and it pulls data from two different tables namely card and transaction. I have created a datagridview to see the result, however when I try to filter the result, nothing is returned to fatagridview.

I'm trying to bind a datagridview to a tableadapter which contains a query that requires parameters (for the WHERE statement of the query). The datasource is a SQL Server database. When I bind the datagridview in design view, it does not let me choose which tableadapter method I would like to use. The way I've been fixing this is to go into the code behind that form, where Visual Studio puts in some auto-generated code that fills a datatable in the dataset and I change the method that it's using there and put in my parameters. I don't think this is the proper way to do it, however, especially because sometimes that code doesn't even get generated! My other solution is to just programatically bind the datagridview to a datatable which I have filled using the tableadapter. This seems like more work than it should be, though.

I have a datagridview and two datatables. I am comparing the information in the two datatables. Now, if the data exists is datatable2 but does not exist in datatable 1 I would like to add a row to the bottom of the datagridview and fill in the necessary information.
Can someone give me an idea of the necessary syntax that I will need to accomplish this goal? Also, I know this post is a little vague and if more information is needed to answer the problem I can give it.

I would like to add a row into a DataGridView: The first column is a string All of the middle columns are of integer type (for sorting) The last column is a string All the values above are passed to the Sub by a array (currentRow) of type String. However, the middle values have to a go through a type change to type Integer for sorting The following Sub works perfect except: The number of items in currentRow (the columns) may vary Then the hardcoded dgProduction.Rows.Add() code at the bottom with not work properly because it is fixed with a total of 6 columns. note that the length of currentRow() will not vary during the population of a single population event. Instead it may vary once I have cleared the grid and click on a different date. So all the rows within the grid will have the same number of columns.

I have a DataGridView that is bound to a DataTable. In this DataTable is a column that contains an image path location, ie; c:imagesmoon.jpg. In the DGV, I'm only displaying 2 columns, the "Name" of the image and the "Image" itself, which basically is the path information. how do I get the image to display in DGV Column? Because even though it's bound...no data comes up when I run the app.
View 1 RepliesI am trying to add and update data in a db from a DataGridView. I have a save button that runs this code. The code works fine. It figures out which rows are new and add it into the DB and which rows are updated and updates them in the DB. BUT if you press the button again it will add the new row in again. it does not mark the new row as one that needs updating when the button is pressed again

I am trying to display unbound data in a DataGridView.I set up columns already design-time. I am at a loss for creating code that adds a new row using the column schema that was created in the Designer?Something like this?

What I'm trying to do is emulate something that we have in C++ in Visual Basic. I have a large table of 25+ columns that I need to display in a grid (don't want a scroll bar). I'd like to use a DataGridView instead of a nightmare of textboxes and add "tabs" to a datagrid view. Lets say the initial tab shows columns 1 - 9, Tab 2 shows Columns 1 - 5 and 10 - 15, tab3 shows 1 - 5 and 15 - 18, etc....

I'm having an incredibly frustrating problem with datagridview that seems like it should have a very simple solution, but I haven't been able to find it yet.I have a form with a datagridview on it that is only usually 1 to 2 rows long but can be much longer. So when the form loads it populates the datagridview with values for however many rows there should be, and there is a blank last row. On the column header on that last row is an asterisk. If you click on the asterisk or anywhere in the blank line, it adds a new row where you can enter data, however, the blank line with the asterisk does not move down to be under it. In fact the asterisk stays on that line, and if you click anywhere on that same line, it adds another row, placing it on top of the one that was just added, and this can happen forever. I have a sub that refreshes the whole table and repopulates, however I can't run it in the new line code with an "Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function." which I can't seem to get past. If I exit the form however and come back in (it runs the refresh on loading), now all the lines that were added show up, with a blank line with an asterisk at the bottom.
View 1 RepliesI have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I have a Datagridview with a bound datatable in it. Then I add a check box column to it.
When I click the headder of the DGV, it sorts the bound columns, and clears all checked checkboxes in the checkbox column.
How do I bind the checkboxcolumn to the rest of the table?
I have a program where i let the user dynamically add DataGridViews to the interface, those are also added to a list for easy management. All of the DataGridViews have their own datasources. I am using a Databinding source to get different DataGridViewTextBoxColumns to add.
The problem is the following: When the user adds the first table the following code runs:
dataGridList(dataGridList.Count -1).Clear()
dataGridList(dataGridList.Count -1).Add(NameDataGridViewTextBoxColumn)
No problem there and the right data is displayed, but when the user adds the second table i get an exception thrown:
"Provided column already belongs to the datagrid view"
I think this is strange since i access different DataGridView's right?
The point of all of this is to be able to view different columns in all the DataGridViews depending on the users choices.
actually i have 3 fields in database which are Sid Fee status what i want to add combo column in field [status] with two option PAID or UNPAID which a user can select and update it .i am all clear with filling the datagridview from database and updating but only problem is adding a combobox in third field that is status.
i tried it with this

Has anyone here tried putting a combobox to a bound datagridview? The selected value of the combobox will depend on the value of the corresponding column in the database.
I have a datagridview. When the user clicks the edit button, the application fetches the records from the database and binds it to the datagriview. But I want to show the Gender Column as combobox with selectable 'Male' and 'Female' values.

I have a datagridview bound to a datatable and i want to add a line to it. I cannot add al ine to the dgv, because it is bound so i add the line to the datatable using Me.BurdensCRMDataSet.dtlines.Rows.Add() however this seems to add two rows - let me explain a little further: A dgv always seems to have what i would call a 'blank next' row, a blank row at the end of the dgv, which as soon as the user populates with data another blank row appears after that - maintaining this 'blank next' row provides a simple and easy way for users to keep manually adding data to a dgv
This also seems to work fine when the dgv is bound to a datatable, an empty dgv would have 1 row (the 'blank next' row) and the datatable would have 0 rows, each time the user populates the 'blank next' in the dgv it is added to the datatable and a 'blank next row is added to the dgv, so the dgv now has 2 rows and the datatable has 1 - and so on and so forth However, I cannot programatically populate this 'blank next' row on the datatable, because it doesn't exist yet in the datatable, only in the dgv and if I programatically populate it in the dgv it isn't added to the datatable and a 'blank next' row isn't added to the dgv
