Access the .NET Server Controls using javascript easily

• There are many developers that are depend on intellisense provided by Microsoft Visual Studio.
• But some times it may not work for scripting, though in VS 2012 and higher version it quite run much good.
• So here are some of the JS code that I would like to share with developers for accessing the .NET controls and how to retrieve and set value to controls.
• Get Label Value:
• $('#<%=Label.ClientID%>').text();
•  Set label value:
• $('#<%=Label.ClientID%>').text("New Value");
•  
• Get Textbox value:
• $('#<%=TextBox.ClientID%>').val();
•   Set Textbox value:
• $('#<%=TextBox.ClientID%>').val("New Value");
•  Get Dropdown value:
• $('#<%=DropDownList.ClientID%>').val();
•  Set Dropdown value:
• $('#<%=DropDownList.ClientID%>').val("New Value");
•  Get text of selected item in dropdown:
• $('#<%=DropDownList.ClientID%> option:selected').text();
•  Get Checkbox Status:
• $('#<%=CheckBox.ClientID%>').attr('checked');
•  Check the Checkbox:
• $('#<%=CheckBox.ClientID%>').attr('checked',true);
•  Uncheck the Checkbox:
• $('#<%=CheckBox.ClientID%>').attr('checked',false);
• Get Radiobutton Status:
• $('#<%=RadioButton.ClientID%>').attr('checked');
•  Check the RadioButton:
• $('#<%=RadioButton.ClientID%>').attr('checked',true);
•  Uncheck the RadioButton:
• $('#<%=RadioButton.ClientID%>').attr('checked',false);
•  Disable any control:
• $('#<%=TextBox.ClientID%>').attr('disabled', true);
•  Enable any control:
• $('#<%=TextBox.ClientID%>').attr('disabled', false);
•  Make textbox read only:
• $('#<%=TextBox.ClientID%>').attr('readonly', 'readonly');

• For getting the data you may also use as what I have said in previous blog, that is simpler

ORA:06413 Connection not Open

• This blog is for those who want to connect Visual Studio with Oracle Database 10g or lower upto 9i.
• I seen there are lots of problem while connecting the Visual Studio with the Oracle 10g and 9i.
• I would like to share that Oracle has already left the support for the same & so as the patch for connection.
• Then instead of using Oracle 10g or 9i client for connection with Oracle Server use the client for which Oracle Corporation use to give support. 
• I had the same problem , all code and path variable were  checked and  were perfect. But then also Client was not connecting to oracle 10g Server.
• Even though from SQL PLUS  it was connected. 
• Thereafter I just uninstalled Oracle 10g client and installed Oracle 11g R2 32-bit and placed tns file in ADMIN folder of OracleHome. 
• I checked once again from VS 2010 and VS 2012 and executed code. The server was connected. 

For any query you may comment . Yours comments would be appreciated.

Get the data from server controls using javascript in asp.net

• Today I'll show you how to retrieve the server controls data easily using Javascript in ASP.NET.
• Normally people I have seen use to retrieve the data from controls is using  something like this:

function validate()

{

     var text=document.getElementById('<%=TextBox1.ClientId%>').value;

   // do stuffs

}

• And then more code for if you want dropdownlist data and some other controls.
• Instead simply one can use String function as (e.g. for DropDownList):

function validate()

{

     var text=String('<%=DropDownList1.SelectedItem.Text%>');

     var  value=String('<%=DropDownList1.SelectedItem.Value%>');

   // do stuffs

}

• That was for this blog have a great day. And yes any one having difficulty can comment anytime.

Insert the data/password by using Cryptography (Encryption/Decryption)

• Always store password using reversible encryption so as the encrypted password can also be decrypted when need to be used.
• But at the same time it is also important to use the strong encryption algorithm.
• Here I'll demonstrate you one of the method for encrypting the data and storing them into database. And Vice-versa.

• Two Class file one is DBAccess where all database stuffs are done and another EncDecClass file for encrypting and decrypting the data.

• This code shows the button click event for storing the encrypted password into database. It calls "Encrypt" method of Class file for encrypting the password.

• Before encryption you should generate a key which is as shown below.

• Now let us see how Encrypt method works:

• And in the same way for decryption. We'll call decrypt method from codebehind file for decryption of password .
• This code shows the button click event for retrieving the encrypted password into database. It calls "Decrypt" method of Class file for decrypting  the password.

• Now let use see how the decryption works.

• And yes this is it.  Here your password get decrypted.
• For more information leave comments please.
• And let me know the difficulties you are facing I'll definitely try to sort it out if I had gone through it.
• Good Luck!
