ROWUPDATING IN GRID

Published on : 2017-04-29 06:00:35

About the authoradd controls in your page_load rowupdating in grid. Use this event to read or initialize control properties. Code for business access layer using system; } above method will fire when update link will be clicked for a particular row of the gridview in edit mode. Here, i have assumed that you will create the respective stored procedure yourself into the database or you may download attachment from http://www. ) and copy-paste folowing code (your can overwrite your default written code for the class file by pasting this code). Add a class named by right clicking app_code folder. Designing 3-tier architecture for the ease of understanding, i have created bal, dal into the app_code folder. – vijay sirigiri feb 15 11 at 7:26      @ vijay : hi vijay, the value in e. Consider this code //your collection of objects goes here. Load the page calls the onload event method on the page, then recursively does the same for each child control, which does the same for each of its child controls until the page and all controls are loaded. [1] furthermore, you are not doing this the way it should. Conclusion by using 3-tier architecture in your project you can achive 1. As we don t have any business logic here so simply instantiate the persondal3 class of dal and call methods. Add(imb); } } void imb_click(object sender, imageclickeventargs e) { response rowupdating in grid.

Aspx or windows form where data is presented to the user or input is taken from the user. Data access layer lets proceed with desiging 3-tier architecture. In the above method, i am instantiating personbal3 and calling the update method by p[assing required parameters.

It might be something different than //this, but basically a dictionary goes fine public dictionary ids { get { return (viewstate[ ids ]. To do that lets proceed with dal, bal and then ui. Now we have all set to go, now just run your project and try inserting records. All the initialization, like adding event handlers, and adding controls should be added during initialization, as the state is saved between page cycles. Data access layer (dal) using system; } in the above code, i have a member variable called connstr that is getting database connection string from my web. Aspx article and look for app_data folder for complete database structure and stored procedure for this article. I will call it business access layer in my demo. Independence - layers are established so that if one is modified (to some extent) it will not affect other layers. Use the onload event method to set properties in controls and establish database connections.

Handling with the content of controls and the viewstate, should be done in load. Business access layer (bal) or business logic layer bal contains business logic, validations or calculations related with the data, if needed.

. Reusability - as the layers are seperated, it can exist as a module that can be reused by other application by referencing it.

That connect ot sql db and fetch in the dataset. I am not goint into details of how i am connecting database and manipulating the data just to make this tutorials short. Commandargument)]); } [1] (ctrl+c/ctrl+v from some other question i answered last week): everything that has to be maintained between page cycles should be declared in page_init, not page_load. Is the data bound to the gridview, your gridview markup doesn t say that it is bound to categoryname. Seperation - the functionality is seperated from the data access and presentation so that it is more maintainable 2. I bind that with my gridview – nayeemkhan feb 16 11 at 9:24 add a comment |  3-tier architecture in asp. .Free sexting chat room with no sign up.Online sex webcams free no registration.
