Pass data between forms, to DataGridView within multiple containers

Question

Hello everyone, a lot of greetings and thank you very much to everyone who takes the time to see this publication and thanks to anyone who can help me. I am trying to pass data from two textboxes that I have in Form2, here I put the button code, but it gives me an error. See who can help me. In Form1 I have a DatagridView, it is where I want to pass the data, but the path gives me an error The DatagridView is inside a TabPanel1 , contained in the TapControl1 , this in turn you are inside a Panel1 of a SplitContainer1. private void btnEnter_Click( object sender, System.EventArgs e) { Form1 dato = new Form1 (); foreach (Form crl in Application.OpenForms) { if (crl.Name == " Form1 " ) { dato = (Form1)crl; dato.splitContainer1.Panel1.TabControl1.tabPage1.DataGridView1.Rows.Add(txtName.Text, txtCity.Text); this .Close(); break ; } } }

Hey Alynson Torres, The code you have shared is wrong. Just pass the textbox values from the form 2 as static string values and access the same string values on form 1 and add them in datagrid. Revert back if any query and select as correct answer if it solves your query.

Hello Alynson, My first sugestion is for you is please goback and read and practice some basic Oops concept, Properties, Delegates and Events, SOLID Princeples, Design Patterns etc. dont take my words in wrong direction because your code very bad so. you can complete your task using Delegate and Events(Best way in your case) or by using properties( with singleton design pattern implemetation in Form1(Parent Form/Class)) other ways also there to complete your task. i have added comments for your code please go through carefully and as i suggest you to complete your task using 1) Delegate and Events or 2) properties, singleton patterns. private void btnEnter_Click( object sender, System.EventArgs e) { // Do not create parent class object in child class. //Form1 dato = new Form1 (); // wrong way to do this in child form/class/popup //foreach (Form crl in Application.OpenForms) //{ // if (crl.Name == " Form1 ") //{ // dato = (Form1)crl; //Below in not correct way to access parent form controls // dato.splitContainer1.Panel1.TabControl1.tabPage1.DataGridView1.Rows.Add(txtName.Text, txtCity.Text); //Do something here to achieve your task this .Close(); // closing child form after click on button is correct. //break; //} //} }
