DataGridView Keeps Replacing First Row Instead Of Adding New
Apr 29, 2012
I have a datagridview which gets it's info from a datatable. Everytime I add a new record to the datatable, the datagridview replaces the first record with the new one, instead of adding the new row under the old row.
(Datatable is already declared.)
Private Sub btnWebSave_Click(sender As System.Object, e As System.EventArgs) Handles btnWebSave.Click
'first make sure all text boxes are full of data.
Dim ds As New DataSet
dt = New DataTable

how to replace a string in a datagridview with another string?
e.g I have a column which has texts "Text1","Text2" that repeate many times in the column. How can I search-replace "Text1" with "anothertext1" and "Text2" with "anothertext2"?
I searched in datagridview members but I didn't find how to do it.

I using vb.net vs2008.
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.

I 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 having problems adding a new row to a datagridview control in my form. I have a simple formwith a textbox, a button and a datagridview. When the user types in an item number and clicks on the button, the system will populate the datagridview with the relevant data from the database.All these works fine but, when the user tries to add another record, the first record added to the datagridview is cleared off the datagridview before the next record is displayed. I would like the datagridview to add all the records without clearing the screen. The datagridview is not bounded to the database.

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 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).

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.

I 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.

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.
How could I add a combobox to bound datagridview?

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

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim dt As New DataTable()
dt.Columns.Add(New DataColumn("Make", GetType(String)))
dt.Columns.Add(New DataColumn("Model", GetType(String)))

How do I manage to append the previous entry in the datagridview so multiple rows get added?
