I know it'll be simple for you guys| call takes 1 overload???

Question

Hi Just wondering if you could tell me what im meant to put in the Call() brackets. private void Call( DataGridViewCellEventArgs o) { int rowIndex = o.RowIndex; string t = dataGridView2.Rows[o.RowIndex].Cells[ Name ].Value.ToString(); textBox1.Text = t; } private void button3_Click( object sender EventArgs e) { Call(); } } Thanks Anthony

DataGridViewCellEventArgs is the class derives from EventArgs class and generally it populates with information when DataGridView event happens. As I can see you are passing this type in button_click event where it should pass through datagridview event. Normally you can write DataGridViewCellEventArgs obj = new DataGridViewCellEventArgs(  ) Pass this obj to the Call method. ColumnIndex & RowIndex is mandatory field and you have to specify. Thanks.....

Yes it needs a DataGridViewCellEventArgs object and a DataGridViewCellEventArgs object is designed for use by an event handler. The better solution would be to take whatever parts of the Call method that you need done when the button is clicked and make that part a separate function. It is very difficult for me to explain what I am trying to say since you don't say what it is that you need to be done when the button is clicked. Based on the code you have posted there is absolutely no reason to call Call from the button click event; just use the code I show. Why can't you do that? Why must you call Call?

Hi Sam I just want to be able to call that function with another but it keeps erroring because it says call needs at least 1 overload. Thanks Anthony

Sam Hobbs · Answer

Oh Anthony. You are using obj in the same line that you are creating it. It (obj) does not exist until after that line has completed. So you can use something like the following. if ( dataGridView2 .SelectedRows != null ) string t = dataGridView2.SelectedRows[0].Cells[ Name ].Value.ToString(); And then you don't need to call Call . If however there is more that the Call method does and you must call Call then say so and we will figure out how to do that.

Hi Can you tell me why this is an error please? public void Call( DataGridViewCellEventArgs o) { int rowIndex = o.RowIndex; string t = dataGridView2.Rows[o.RowIndex].Cells[ Name ].Value.ToString(); textBox1.Text = t; } private void button2_Click_1( object sender EventArgs e) { DataGridViewCellEventArgs obj = new DataGridViewCellEventArgs ( obj .ColumnIndex  obj.RowIndex); Call(obj); } it errors on obj saying use of unassigned variable. On button click im trying to convert the select row with column Name to a textbox. Thanks Anthony

It depends on what you meant the program to do when button3 is clicked. It is not a matter of what the program meant for you to do it is what you meant the programn to do. Understand the difference? We don't know what you meant for the program to do so we can only guess. I hope that Subhendu guessed correctly but if not and you want a more accurate answer then you need to describe the problem more accurately.
