How to Create WebPartManager Control in code

The WebPartManager Control

The WebPartManager control acts like a centralized hub that manages all the other Web Parts controls on a Web page. This control coordinates the interaction between Web Parts and Web Parts zone. The WebPartManager control manages the personalization states of Web Parts controls on a Web page. Personalization allows storing of User information and all the runtime customization (defined by the user) in a persistent storage (typically SQLServer database). These customizations are loaded when the user visits the website the next time. If you create a Web page that uses Web Parts controls, ensure that the page contains a WebPartManager control . There must be only one intance of the WebPartManager control on each Web page that uses the control, and it must be placed before other Web Parts Zone controls are placed on the Web page. The WebPartManager control is an object of the WebPartManager class.

The WebPartManager control performs the following tasks to control the functionality of a Web page.


  • Keeping track of different controls on a Web page.
  • Inserting and removing controls on a Web page 
  • Establishing , monitoring and managing connections between various Web Parts controls.
  • Enabling you to customize the appearance of a Web page by dragging various controls to different locations on the page.
  • Providing various views , Which you can use to change and personalize the properties and behavior of controls.
  • Enabling you to toggle between different views of a Web Page , Thereby simplifying certain tasks, such as modifying layout and editing controls.

Using the WebPartManager Class

The WebPartManager class allows users to toggle between various display modes . These display modes help the user to perform different actions on the Web page, such as changing the layout of a Web page or editing controls, and the rest. The WebPartManager class has the following five display modes:
BrowseDisplayMode- Specifies the default display mode for pages that contain Web Parts controls.
CatalogDisplayMode-Specifies the display mode in which a catalog of controls is visible . A user can add controls to a Web page from the catalog.
ConnectDisplayMode- Represents the display mode in which the connection UI is visible and where users can manage the connections between the controls of Web page.
DesignDisplayMode- Represents the display mode in which the user can modify the layout of a Web page.
EditDisplayMode- Specifies the display mode in which the user can change the appearance , properties and behavior of server controls.

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 …
