Question

Hi All,

 

I wrote code for showing dynamic data. i am able to getdata but problem is while clicking second page everything is gone . please any one help me. 

below is my code.

model:

public DataTable GetreferenceDT()

{

ValidatorServiceClient client = new ValidatorServiceClient();

ReferenceTableDataSet = new ReferenceTablesDetails();

if (!string.IsNullOrEmpty(referanceData))

{

ReferenceTableDataSet = client.GetReferenceDatabytableId(referanceData);

}

return ReferenceTableDataSet.ColumnInformation.Tables[1];

}

public List<dynamic> ConvertDtToList(DataTable dt)

{

var data = new List<dynamic>();

foreach (var item in dt.AsEnumerable())

{

// Expando objects are IDictionary<string, object>

IDictionary<string, object> dn = new ExpandoObject();

foreach (var column in dt.Columns.Cast<DataColumn>())

{

dn[column.ColumnName] = item[column];

}

data.Add(dn);

}

return data;

}

Controller:

 

[HttpPost]

public ActionResult ReferenceData(ReferanceDataModel referenceModelValue)

{

DataTable dt = referenceModelValue.GetreferenceDT();

referenceModelValue.ColumnNames = new List<System.Web.Helpers.WebGridColumn>();

foreach (DataColumn col in dt.Columns)

{

referenceModelValue.ColumnNames.Add(new System.Web.Helpers.WebGridColumn()

{

ColumnName = col.ColumnName,

Header = col.ColumnName

});

}

referenceModelValue.TableColumnValues = new List<dynamic>();

referenceModelValue.TableColumnValues = referenceModelValue.ConvertDtToList(dt);

return View(referenceModelValue);

}

 

View:

 

@{

List<dynamic> dynamicValues = new List<dynamic>();

dynamicValues = Model.TableColumnValues;

if (dynamicValues != null)

{

var grid = new WebGrid(dynamicValues);

<div id="gridContent">

@grid.GetHtml(

tableStyle: "webGrid",

fillEmptyRows: false,

alternatingRowStyle: "alt",

headerStyle: "header",

emptyRowCellValue: null,

columns: Model.ColumnNames

)

</div>

}

}

 

UI:
