How to change value of a column in DataGridView?

Question

Hiii,

In a C# WinApp, I have a form with a DataGridView and a ComboBox. the DataGridView contains columns i.e. No; Perticular, Quantity, Rate, Amount and Days. the ComboBox contains number 1 to 365.

Now, I am trying to change the 6th column (Days) using the ComboBox numbers. I want to do it as if I select '10' from the ComboBox all the cells in the Days column get that value. In short, I want to change the entire column value with the value selected from the ComboBox regardless, how many rows are there in the gridview.

 

Anybody please help.

 

Thank You.

Answer 1

Use this code in selected index changed event of combobox

 

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

{

   dataGridView1.Rows[i].Cells[6].Value=comboBox1.SelectedValue;

}

 

 

Answer 2

Hii Ranjit,

thank you for your reply. there is just one little change I have to do that is instead of 'combobox1.SelectedValue' I added 'SelectedItem'. it is because when I used SelectedValue, and changed the value from combobox, all the values went blank...

 

'combobox1.text' also works.

 

anyway, my problem is solved.

thank you once again.
