Viewing rows from database.

Posted By:      Posted Date: August 27, 2010    Points: 0   Category :ASP.Net
 

 Hi ,

Let me share with you my question.

Scenario: Table Name:Emp ,Columns:id,name,sal

I have a combobox which is populated by id which is there in a database. And two Textboxes Name,Sal to insert Name and Salary of the Employee. I have no problem in inserting the datas to database and viewing all the inserted datas.

I got issue when I tried to view name and salary of the employee when a particular id is selected from combobox and finally clicking on a button to get the name and salary in the textboxes.


string str = ComboBoxName.getSelectedItem();

and a command as :"Select name,sal from Emp where id = +str"

XML with PrimaryKey values to delete rows in database table at a time

  

 Hi,

I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in my case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.

My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??

If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..

My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List??

WHich one is better, I mean ObjectDataSource or SQLDataSource or my XML method??

Can anyone please help me out clarifying my doubts and also XML Delete Query..

 

My XML will be like this

 

<root>

<Customer>

<CustomerID>GUID1</CustomerID>

<CustomerID>GUID2</CustomerID>

<CustomerID>GUID3</CustomerID>

 ...

 ...

</Customer>

</root> 

Will bulk delete happen in the above case?

Thanks,

PAvan


Multiple database support with Entity Framework

  
One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

Export Visio Database Table Names to Excel

  
If you use the Enterprise Architect edition of Microsoft Visio for data modeling regularly, then there is a good chance that at some point you've wanted to export just the table names into Excel. You might want to do this to map logical ERD entities to physical data model tables, track project status by entity, or track overlap between database versions.

Adding Dynamic Rows in ASP.NET GridView Control with TextBoxes and with Delete functionality

  
In my previous examples, I have demonstrated on how to add dynamic rows in GridView control with TextBoxes and how to save the values into the database. Now, seems that most of the developers are asking if how to add a delete functionality with it. So in this example, I'm going to show on how to delete a certain row in the dynamic GridView with TextBoxes.

jQuery: Highlight Gridview Rows with Checkbox

  
Im learning and experimenting with jQuery and ASP.NET. Below is a simple solution I created to highlight rows in a gridview by clicking on a checkbox next to the row.

Gridview setup:

MS SQL Server: Disconnect Users From Database - Kill User Session

  
If you ever wanted to restore your database from a SQL backup file (.bak), but there are still users connected to your database, the backup operation will fail causing the error: Exclusive access could not be obtained because the database is in use.

Highlighting Rows with TextBox OnFocus

  
In another article I explained that how you can make the rows of the GridView control clickable and highlight them when they are clicked. In this article I will explain that how you can highlight the GridView rows when you focus on the TextBox which is contained inside the GridView control.

jQuery: Styling DropDownList Alternating Items (Rows)

  
In the following example, I will show how you can style any asp:dropdownlist very easily.

The example demonstrates how you can change alternating row items background color, using the fadeTo() to add a nice touch in the dropdownlist. You can change alt rows with a couple lines.

MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

  
If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

How to format and update GridView and DataGrid rows using JQuery

  
The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

Publishing SQL Server Database using Publishing Wizard : Tips & Tricks

Using jQuery to Filter Table Rows

  
The project is using the .net GridView control, so I had limited control over the output HTML code. Still, I think this code can work for most tables. One thing to notice: you should use the class "filterable" on your table or on one of its parents for the code to work.
First, we need a text box:

Insert Rows with a GridView

  
In ASP.NET version 1.x, I used the footer on the DataGrid control to insert new rows by placing a series of TextBox, DropDownLists, CheckBoxes etc. controls on it and then handling a save button. This also works with the GridView in version 2.0 but with one major exception: if your data source is empty, the GridView will hide your footer (and header) and only display the EmptyDataText.
