How can I get the value of two specific cells in the DataGridView and store them in variables

How can I get the variables that are in two specific columns in DataGridView, for example I want the Id that is in the first column and the name that is on the third. How can I do that? I'm trying the RowEnter event but when I searched online I can't find anything that I can follow up. Thanks guys.
private void dataGridViewDocumentos_RowEnter(object sender, DataGridViewCellEventArgs e)
{
DataGridViewRow dgvr = dataGridViewDocumentos.SelectedRows[0];
dgvr.Cells[];
foreach (DataGridViewRow Datarow in contentTable_dgvr.Rows)
{
if (dgvr.Value != null && Datarow.Cells[1].Value != null)
{
int contentJobId = 0;
contentJobId = Datarow.Cells[0].Value.ToString();
contentValue2 = Datarow.Cells[1].Value.ToString();
MessageBox.Show(contentValue1);
MessageBox.Show(contentValue2);
}
}
}
This is what I have right now, as you guys can see I'm missing a lot of things, I'm not familiar with this so if you guys can point what I need to do I'd appreciate it.

Well, the 1st question is, is this on a button click outside the grid? Or is this in response to an specific event that has happens? The reason why I ask that is because in your code sample you are using the RowEnter event which will fire everytime the row recieves input. I am not sure if that is what you want ot not.
Anyway, I mean you are pretty much there with your code sample. If you want to get the selected 1st and 3rd column for the selected row you could use this code.
private void dataGridView1_RowEnter(object sender, DataGridViewCellEventArgs e)
{
var activeCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
var fistColumnCell = dataGridView1.Rows[e.RowIndex].Cells[0];
var thirdColumnCell = dataGridView1.Rows[e.RowIndex].Cells[2];
MessageBox.Show(fistColumnCell.Value.ToString());
MessageBox.Show(thirdColumnCell.Value.ToString());
}
Notice that the 2nd paramater of the function named DataGridViewCellEventArgs has properties for ColumnIndex and RowIndex which you can use to get the currently selected row.
However, if this code should fire in response to a user double clicking a cell you could use the CellDoubleClick event
private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
var fistColumnCell = dataGridView1.Rows[e.RowIndex].Cells[0];
var thirdColumnCell = dataGridView1.Rows[e.RowIndex].Cells[2];
MessageBox.Show(fistColumnCell.Value.ToString());
MessageBox.Show(thirdColumnCell.Value.ToString());
}

Removing the default selected row on datagridview

i have a Datagridview that contains columns.
when i click on the item on the column.
it always select the first row
i also tried
.currentcell = null and .clearselection();
// i inserted this one on the form_load
but nothing happens.
here is my code
private void dgv1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex == 0)
{
dgv1.CurrentCell = null;
dgv1[e.ColumnIndex, e.RowIndex].Value.ToString();
if (Path.GetExtension(path) == ".pdf")
{
Process.Start(path);
}
}
}

What do you want the user to select in the first place?
There is a property for selectionmode in datagridview.
Change it to CellSelect if you want it to select cells only.
Alternatively, use dataGridView.SelectionMode = DataGridViewSelectionMode.CellSelect;
After reading what you said on the comment, from that I infer that you are trying to click a cell and read the cell from your program?
If so, you could try
dataGridView[e.ColumnIndex, e.RowIndex].Value.ToString();
on the CellContentClick and/or CellClick event

How do I execute code after a certain checkbox is selected

I have a datagridview with multiple checkboxes. When the Finished checkbox is checked I need to execute linq code to update a specific table. How do I find out if that specific check box is dirty and where do I write the code to pass the values I need to be passed to the table. Note that it is not the same table that the datagridview is based on.
Thanks.
EDIT:
private void propertyInformationDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)propertyInformationDataGridView.Rows[e.RowIndex].Cells[3];
DataGridViewRow row = propertyInformationDataGridView.Rows[e.RowIndex] as DataGridViewRow;
System.Data.DataRowView SelectedRowView;
newCityCollectionDataSet.PropertyInformationRow SelectedRow;
SelectedRowView = (System.Data.DataRowView)propertyInformationBindingSource.Current;
SelectedRow = (newCityCollectionDataSet.PropertyInformationRow)SelectedRowView.Row;
if (Convert.ToBoolean(checkCell.EditedFormattedValue) == true)
{
DataClasses1DataContext dc = new DataClasses1DataContext();
var matchedCaseNumber = (from c in dc.GetTable<PropertyInformation>()
where c.CaseNumberKey == SelectedRow.CaseNumberKey
select c).SingleOrDefault();
reportsSent newReport = new reportsSent();
newReport.CaseNumberKey = SelectedRow.CaseNumberKey;
dc.reportsSents.InsertOnSubmit(newReport);
dc.SubmitChanges();
}
}
Do I need to endedit at some point is that the issue?

This is from some of my code, all you need to do is create a "CellContentClick" event for your datagridview.
The easiest way to do this is select the Datagridview, go to properties and click on the lightning bolt. Scroll down to "CellContentClick" and double click in the empty box. This will auto generate the method you need to paste the following code into.
Make sure you rename my instances of "CustomersDataGridView" to whatever yours is named as well, intellisense should highlight invalid code in red that you need to replace.
Also, the "9" you see in the checkCell declaration needs to be changed to the index of your "Finished" check-box. If it is in the 3rd cell from the left, put a 2 there instead of a 9, as the indexing is 0 based.
EDITTED to fix comments:
private void CustomersDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex.ToString() == "9")
{
DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)CustomersDataGridView.Rows[e.RowIndex].Cells[9];
DataGridViewRow row = CustomersDataGridView.Rows[e.RowIndex] as DataGridViewRow;
if (Convert.ToBoolean(checkCell.EditedFormattedValue) && CustomersDataGridView.IsCurrentCellDirty)
{
//Do Work here.
var z = row.Cells[0].Value; // Fill in the brackets with the column you want to fetch values from
//z in this case would be the value of whatever was in the first cell in the row of the checkbox I clicked
}
}
}

You can do it in the CheckedChanged-Event
private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
// Do what you have to do...
}

how to check whether gridview's row is selected or not in c#.net windows application

I want to know how to check whether a gridview's row got selected or not.
I am working on windows application.
I want to put a if condition ie if a particular row gets selected then fill the textbox with the correspoding cell value.
I am just not getting the way how to give the condition in the if clause.

Handle the DataGridView.SelectionChanged event. Use the DataGridView.SelectedRows property to get the selected rows collection.
private void dataGridView_SelectionChanged(object sender, EventArgs e)
{
// Update the text of TextBox controls.
textBox1.Text = dataGridView.SelectedRows[0].Cells[1].Value.ToString();
textBox2.Text = dataGridView.SelectedRows[0].Cells[2].Value.ToString();
....
}

Check DataGridViewRow.Selected property.
if (dataGridView.Rows[rowIndex].Selected)
{
// Do something ..
}

Check the selected property of DataGridViewRow, it returns true for selected else false.
bool isSelected = dataGridView1.Rows[e.RowIndex].Selected;

You can subscribe to the SelectionChanged event of the control and iterate through each selected row if multi-selection is enabled or just the first one if single-row selection only.
private void MyGridView_SelectionChanged(object sender, EventArgs e)
{
for (int i = 0; i < MyGridView.SelectedRows.Count; i++)
{
MyTextBox.Text = MyGridView.SelectedRows[i].Cells[0].Value.ToString(); //assuming column 0 is the cell you're looking for
// do your other stuff
}
}
More information can be found on the SelectedRows property.

C# dynamically taking data from DataGridView

I'm trying to get my current program to take information from a dynamically created DataGridView. I have managed to get the information into the grid, and perform the required search, however now I'm really stuck.
I have added a column to the datagridview which holds a button within each row. What I'd like to do is take the value of the data from column index 1 which is in the same row as the button clicked. Confusing? Anyway, here's the code:
public void GetValues(...)
{
//Details regarding connection, querying and inserting table
.
.
.
DataGridViewButtonColumn buttonCol = new DataGridViewButtonColumn();
buttonCol.Name = "ButtonColumn";
buttonCol.HeaderText = "Select";
buttonCol.Text = "Edit";
//NB: the text won't show up on the button. Any help there either?
dataGridView1.Columns.Add(buttonCol);
dataGridView1.CellClick += new DataGridViewCellEventHandler(dataGridView1_CellClick);
foreach (DataGridViewRow row in dataGridView1.Rows)
{
DataGridViewButtonCell button = (row.Cells["ButtonColumn"] as DataGridViewButtonCell);
}
dataGridView1.Columns["ButtonColumn"].DisplayIndex = 0;
}
void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
//Here is where I'm having the trouble. What do I put in here???
}
Thanks for any help you can give!
David.

Your DataGridViewCellEventArgs contains very useful information such as RowIndex.
So something like (I don't know what you want to do with the value):
String dataYouWant = dataGridView1.Rows[e.RowIndex].Cells[1].Value;

`
if (e.ColumnIndex != button_column_number) //column number of the button.
return;
dataGridView1.EndEdit();
bool val;
if ((dataGridView1.Rows[e.RowIndex].Cells[1].Value) != null) // column index 1...as that's what you want.
{
//d stuff you want here.
}
else
{
}
`
