How to Add Commands with Binding in DataGridView: Windows Forms

After binding records with DataGridView, there may be some options to edit or to remove those records. To do these simple task we can provide either a button, which gets the selected record and perform operation, or we can provide the button with each particular record.

We will discuss here how to add a button with particular record with the following simple steps. Drag-n-drop a datagridview on the form and a task pop-up menu will automatically open, click on Add Columns link button to add a new column. It will show following Add Column window.

How to Add Commands with Binding in DataGridView: Windows Forms

By default Unbound column radio button have been checked, if not check it and use the following values in respective fields:
  • Type: DataGridViewButtonColumn
  • Header Text: Command (Changeable)
Sure the Visible check box is checked and click on Add button to add this column. Now you have successfully added a command button with empty text as shown in below image:

To write text on the button generate Cell_Formatting event of dataGridview and set the value of first column as I do in the following c# code:
private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
dataGridView1.Rows[e.RowIndex].Cells[0].Value = "Remove";

When you run the project now, it will show “remove” on the button. To check if this code will works for multiple records or not, add some records in data gridview like How to add Records in Datagridview. Run the project now and it will show the Remove button with each record as shown in the following image:

In the next article I will remove the particular record with this command button.

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 …
