To enable debug operation in SharePoint server web part, follow the following steps


i. Open web.config file of the SharePoint web site in which you want to make debug mode.

<SharePoint>

<SafeMode MaxControls="200" CallStack="true" DirectFileDependencies="10" TotalFileDependencies="50" AllowPageLevelTrace="false">

<PageParserPaths>

</PageParserPaths>

</httpHandlers>

<customErrors mode="Off" />

<httpRuntime maxRequestLength="51200" />

<assemblies>

2.

Fetching multiple SQL query at one time and store in dataset tables.


// Set SQL query to fetch projects

string sqlQuery = "Select * from Projects; Select * from Steps";


// Create dataset

DataSet dataSet = new DataSet();


// Populate dataset

using (SqlConnection connection = new SqlConnection(m_ConnectionString))

{

SqlCommand command = new SqlCommand(sqlQuery, connection);

SqlDataAdapter dataAdapter = new SqlDataAdapter(command);

dataAdapter.Fill(dataSet);

}


// Set dataset table names

dataSet.Tables[0].TableName = "Projects";

dataSet.Tables[1].TableName = "Steps";

3.

Here, main Data Table is objDataTable, It will in sorting by the column 'sd_planned' in ascending after following coding.


//Sorting Data Table

DataView dtview = new DataView(objDataTable);

4.

Using JavaScript in ASP.NET and handling enter key from the client side.


<script language="javascript" type="text/javascript">

function clickButton(e, buttonid){

var bt = document.getElementById(buttonid);

if (bt){

if(navigator.appName.indexOf("Netscape")>(-1)){

if (e.keyCode == 13){

bt.click();

return false;

}

}

if (navigator.appName.indexOf("Microsoft Internet Explorer")>(-1)){

if (event.keyCode == 13){

bt.click();

return false;

}

}

}

}

</script>


For use JavaScript in ASP.NET in dynamic way (Code Behind), we have to call attribute method of the control using following codings


TextBox1.Attributes.Add("onkeypress", "return clickButton(event,'" + Button1.ClientID + "')");

How to Create User Control from Web Page (.aspx to .ascx)


In addition to explicitly creating a user control, we can also convert a Web page to a user control. The primary benefit is that we can do our prototyping and testing without having to deal with placing the control on a Web page.


- Remove the <html>, <body>, and <form> begin and end tags.

- Change the @Page directive at the top of the file to @Control directive.
