How to Access Record by DataGridViewButton: Windows Forms

I have created a DataGridViewButton for each particular record of DataGridView, as in my earlier post. Adding a button is not sufficient in programming, it should perform some functions when clicked, so we have to generate its click event.

In simple words, we can’t generate a click event of this DataGridViewButton using double click or from the events section. As this is in datagridview so generate Cell_Click event of this datagridview. Now, I have added this button in first column, so I can check it on the same.
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
MessageBox.Show("Column: " + e.ColumnIndex + " and Row: " + e.RowIndex);
}

By this simple code, the debugger will execute all your line of code, written in the space provided. ColumnIndex contains the column index and RowIndex contains row index, when this event triggered.

Let suppose, we want to access the record of the clicked row of datagridview. I have bound that datagridview with list of student class, so the following C# lines of code will get the instance of student, which is currently focused by mouse click event.
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
Student stu = dataGridView1.Rows[e.RowIndex].DataBoundItem as Student;
MessageBox.Show("Name: " + stu.Name + "\r" + "Age: " + stu.Age
+ "\r" + "City" + stu.City + "\r"
+ "Dob: " + stu.Dob);
}

The first line will get the particular record, which is of student type. When we run the project and click on the datagridviewbutton it will show a message box, containing the detail of particular student.

difference between structure and union in C Language

In c language article we will see the difference between union and structure. Both are the user define datatype in c language. See the table which is mentioned below: ASP.NET Video Tutorial Series Structure Union1.The keywordstruct is used to define a structure 1. The keyword union is used to define a union. 2. When a variable is associated with a structure, the compiler allocates the memory for each member. The size of structure is greater than or equal to the sum ofsizes of its members. The smaller members may end with unused slack bytes. 2. When a variable is associated with a union, thecompiler allocates thememory by considering the size of the largest memory. So, size of union is equal to the size of largest member. 3. Each member within a structure is assigned unique storage area of location. 3. Memory allocated is shared by individual members of union. 4. The address of each member will be in ascending order This indicates that memory for each member will start at different offset v…

Difference between Linear search and Binary Search in c language

SQL Video Channel : Download all SQL Video



Binary Search Linear Search Works only on sorted items. such as  1,2,3,4,5,6  etc
Works on sorted as well as unsorted items. 12,4,5,3,2,1 etc Very efficient if the items are sorted Very efficient if the items are less and present in the beginning of the list. such as Suppose your list items are : 12,3,4,5,1 and you want to search 12 number then you get beginning in the list. Works well with arrays and not on linked lists. Works with arrays and linked lists.
Number of comparisons are less More number of comparisons are required if the items are present in the later part of the array or its elements are more.

Memory representation of Linked List Data Structures in C Language

Memory representation of Linked List

             In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.

               Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:


      Suppose next node is allocated at an address 506, so the list becomes,



  Suppose next node is allocated with an address with an address 10,s the list become,


The other way to represent the linked list is as shown below:




 In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of next node. The last node …
