Gridview Performance improvement with Custom Paging

Gridview provides excellent features to show the data on webpage. Few of the popular features are sorting, column arrangements, styles, item templates, editing, updating and deleting. Get the data from SQL, DataList, Arrays and bind the data to Gridview and it displays the data in required format. GridView1.DataSource = SQL command Result OR List() OR Array() GridView1.Databind(); When the data is huge and you bind the data with GridView, it can impact the performance of your page. To Overcome that, GridView Paging is provided but it fetches all the records and bind it to GridView and when you click on page number, it shows the records of that page index. GridView paging is also not good solution and hits the performance as it fetches all the records once and then bind it to GridView. Here is the solution which do custom paging and fetches the data when required. GridView with Custom Paging GridView is showing 10 records by default. Clicking on 'Nex

Wrapping the data using <ItemStyle> tag Solution 2: Putting <div> tag and styling on bounded column ( Works on all browsers ) Wrapping the data using <div> tag and styling Output:  Here is the output how data displayed in Gridview is wrapped. Gridview wrapping Keep posting your queries to get optimum solution.

Sitecore Best Practices

Design Prospective: 1. Put components statically in html if it is being used multiple times and not much changes required. Use placeholders only to bind those components which are getting change frequently. 2. Always set presentation details on _standard values. 3. Do appropriate image resizing on server else it will slow down the performance when opening on browse. 4. Create template for providing data to presentation component. 5. Get the Data from DataSource from component Parameters to get variations. Code Prospective: 1. Test your html/css/javascript code in such a way that Page Editor is enable for edit by non technical staff. 2. Given meaningful names to placeholder so that right component could add under right placeholder. 3. Write code using C# coz this is language generally use by Sitecore Support team. Use GUID instead of path/name as content can be moved to some other location in content tree. 4. Create separate config file for your component instead of adding directly in w

Sitecore customization using pipelines

A pipeline consists of a number of processors arranged in sequence to process a common set of parameters. If I have a series of tasks, which need to be performed to accomplish a task, then a pipeline may be the way to go. Instead of passing to each processor an arguments object containing these parameters, the pipeline class itself exposes properties representing the parameters. Sitecore pipelines also allow an object to pass through each step. This object can be manipulated by any of the steps and passed through to the next step until the end is reached and the object can be used by whatever executed the pipeline in the first place. In configuration file, you will be able to see numbers of pipelines, which is default from sitecore. You can create your own custom code and add pipeline to execute that code. Example: Pipeline contains parameter ‘type’, which contains information about class and assembly as shown in snapshot. UI customization using pipelines Each step in pipeline is calle
