How to bind LINQ data to dropdownlist (TEXT,VALUE)

Let's assume we have a Web Service which will return the results as an object with the values DDLTEXT
and DDLVALUE.
The following will explain how to use LINQ to query and then bind the results to the
DropDownList:  DataTextField and  DataValueField

ddl.DataSource = wsMethod.Contents.OrderBy(o=>o.DDLTEXT);

//specify result object values
ddl.DataTextField = "DDLTEXT";
ddl.DataValueField = "DDLVALUE";

ddl.DataBind();

How to bind LINQ data to DataGrid

Let's assume we have a Web Service which will return the results as an object for IN and OUT data records.

The following will explain how to use LINQ to query and then bind the results to the asp:DataGrid

C# code:

//query to get currunt month data ordered by LOCAL_TIME then TYPE

 var thisMonthData = eData.Contents

.OrderByDescending(o => o.LOCAL_TIME)

.OrderByDescending(o2 => o2.TYPE)

.Where(m => m.DATE.Substring(0, 6)

== DateTime.Today.ToString("yyyyMM", arCulture));

 

//Bind Data

eDataGrid.DataSource = thisMonthData;

eDataGrid.DataBind();

 

//query to get currunt month data ordered by LOCAL_TIME for TYPE=IN

var thisMonthDataIn = eData.Contents

.OrderByDescending(o => o.LOCAL_TIME)

.Where(r => r.TYPE == "IN")

.Where(m => m.DATE.Substring(0, 6) == DateTime.Today.ToString("yyyyMM", arCulture));

 

//Bind Data

eINDataGrid.DataSource = thisMonthDataIn;

eINDataGrid.DataBind();

 

//query to get currunt month data ordered by LOCAL_TIME for TYPE=OUT

var thisMonthDataOut = eData.Contents

.OrderByDescending(o => o.LOCAL_TIME)

.Where(r => r.TYPE == "OUT")

.Where(m => m.DATE.Substring(0, 6) == DateTime.Today.ToString("yyyyMM", arCulture));

 

//Bind Data

eOUTDataGrid.DataSource = thisMonthDataOut;

eOUTDataGrid.DataBind();
