How to read Rows of a DatagridView through for loop

EhteshamSiddiqui — Sat, 10 Sep 2011 14:56:16 +0000

Hi,
My application is in VS2008 coded in Vb.net.I have a datagridview which is populated from Database.I have a save button on the same form that has DatagridView.
My requirement is i want that all the records that are populated in DatagridView should be saved in a certain table of the database when the user clicks save.
Im done with my save and Update code.What im not able to do is,im not able to increment the counter and move to the next row of datagridView when my For loop is executing after the click of Save button.
Below is my Code.

For i As Integer = 0 To DGVStudRecord.RowCount - 1

My code to Update And Save

Here what is happening is when save button is clicked my for Loop is executing and looping till RowCount-1.But i want that after completion of each loop my i should get to the next row in the datagirdView.I should be able to get the values of next row to pass it to my controls that are carrying update and delete operation.
The entire data in the datagridview will be saved in a certain table at the click of save button.
Please suggest.

EhteshamSiddiqui — Wed, 07 Sep 2011 07:18:32 +0000

Hi,

I have two forms.Both having DatagridView.There are two comboboxes to filter the record from Database and fill in Datagridview.My requirement is when all the data is populated in DataGrid after selecting the comboboxes and when the user clicks on Delete.

The comboboxes and Datagrid on second form should have the same values as that was on first form.The names of my Comboboxes and Datagridview are same on both the forms

Below is the code my Datagrid view getting populated in First Form.

Sub GetData(ByVal StrQuery As String)

If CBMedium.Text <> "" And CBClass.Text <> "" Then

DGVStudRecord.Rows.Clear()

con = DBConnect()

cmd = New SqlCommand(StrQuery, con)

dr = cmd.ExecuteReader

If dr.HasRows Then

While dr.Read

DGVStudRecord.Rows.Add(dr(0), dr(1), dr(2), dr(3), dr(4), dr(5))

End While

End If

con.Close()

End If

End Sub

Please suggest how can i populate my datagrid in second form by using the Data populated in Datagrid of Firrt Form

Limiting character input in specific cells on a DataGridView in Visual Basic.

Trueheartless — Sun, 20 Feb 2011 03:34:12 +0000

I’m making a gradebook program (for a project) but I haven’t touched VB in years. Given it is a simple language, there’s still plenty of things I don’t know about it.

At the moment I’m trying to figure out how to limit the characters a user is allowed to input in each specific cell (20) in a DataGridView. (I’ll also need to figure out how to limit the input to numbers only, but that’s something different right now.)

Any assistance is greatly appreciated.

Datagridview First Rows Not Consider or Skip

Maheshwag — Tue, 05 Oct 2010 14:42:49 +0000

There is some mistake from my previous question hence once again repeat it.

My problem is on datagridview i have populate combobox and amount column. and ColumnHeader/RowHeaderVisible property set to false. I have coding as below.

private void dataGridView1_RowLeave(object sender, DataGridViewCellEventArgs e)

{

double dd = 1.768901;

dd = Convert.ToDouble(dd.ToString("f2"));

DataGridViewCellStyle fixedstyle = new DataGridViewCellStyle();

fixedstyle.Format = "f2";

dataGridView1.Columns[1].DefaultCellStyle = fixedstyle;

try

{

decimal sum = 0.00m;

for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)

if (dataGridView1[1, I].Value != DBNull.Value)

{

sum = sum + Convert.ToDecimal(dataGridView1[1,I].Value);

label12.Text = sum.ToString("f2");

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

My problem is total not counted from begining of the column’s rows “ammount”.

e.g…

1st rows column value=12

2nd rows column value=12

3rows column value= 12

total of column shows is 24 where as actual columns value is 36.

I think first rows column’s total not consider or skip. how to solve it.
