How can I pass data to DataGridView from another form?
-
I just want to pass data to DataGridView from another form? I have 2 windows forms: - from1 contains DataGridView1 and button_frm1.The DataGridView have 3 columns and already have some data (6 rows) and DataGridView1 modifiers = Public. - form2 contains textBox1 and button_frm2. Now, when I click button_frm1 form2 appears and next when I click button_frm2 the value in the textBox should be inserted into DataGridView1 in column0 in the selected row. but instead, I got this error: "Index was out of range. Must be non-negative and less than the size of the collection". Please help me how to insert the textBox value from form2 into DataGridView1 in form1. What steps to follow? Thank you very much in advance. Here is the code I tried: Form1: public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button_frm1_Click(object sender, EventArgs e) { Form2 frm2 = new Form2(); frm2.Show(); } } Form2: public partial class Form2 : Form { public Form2() { InitializeComponent(); } private void button_frm2(object sender, EventArgs e) { Form1 frm1 = new Form1(); textBox1.Text= frm1.dataGridView1.SelectedRows[0].Cells[0].Value.ToString(); } }

Start by looking around at what you are doing: see the bit at the top of teh page? Where it says "Technical discussions are encouraged, but click here to ask your programming question."? Perhaps if you paid attention you wouldn't annoy people, and you might get a better response. Then click on the red bit, and it'll take you here: http://www.codeproject.com/Questions/ask.aspx[^]
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Delete your post and move it to the proper forum for asking coding questions. This is not a good start to your CP career! :thumbsdown:

You can't. DataGridView are very arrogant and won't accept anything coming from someone else.
