コントローラーアクションが剣道UIグリッドに渡すJSONデータをバインドできないという問題で、かなり長い間この問題に直面しています。以前はJavaScriptの問題はほとんどありませんでしたが、今ではそれらはなくなりましたが、それでも私のグリッドはありません結果を表示する:
でModel
:
public object GetResult(string id)
{
var sqlCom = new SqlCommand("SELECT [No],[Desc],[Date],[Height],[Final] FROM [cr_form] WHERE [uId]=@id;", sqlConn);
sqlCom.Parameters.AddWithValue("@id", id);
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
JsonWriter jsonWriter = new JsonTextWriter(sw);
var rcrds = GETSQLRESULTS(sqlCom);
try
{
int i = 0;
if (rcrds != null || rcrds.HasRows)
{
//jsonWriter.WriteStartObject();
while (rcrds.Read())
{
jsonWriter.WriteStartObject(); //Changed
for (int j = 0; j < rcrds.FieldCount; j++)
{
jsonWriter.WritePropertyName(rcrds.GetName(j)); // column name
jsonWriter.WriteValue(rcrds.GetValue(j)); // value in column
}
i++;
jsonWriter.WriteEndObject(); //Changed
}
//jsonWriter.WriteEndObject();
}
}
catch (Exception ex) { }
return jsonWriter;
}
でController
:
public ActionResult GetRecords()
{
var usrObj = new User();
var jsnRslt = usrObj.GetResult(Session["Id"].ToString());
//Till here jsnRslt contains this string: “{"No":null,"Desc":"asfasfasfasfasfasfasfasfasfasfasfasf","Date":"2013-03-27T00:00:00","Height":0,"Final":null,"No":null,"Desc":"etwetwetwetwet","Date":"2013-03-27T00:00:00","Height":0,"Final":0,"No":null,"Desc":"asfasfasfskfjklajsfkjasklfjklasjfklajsfkljaklsfjklasjfkljasfkljlasf","Date":"2013-03-27T00:00:00","Height":0,"Final":0,"No":null,"Desc":"askjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfklaskjfkajsfkl","Date":"2013-03-27T00:00:00","Height":0,"Final":0,"No":null,"Desc":"safasfasfasfasfasf","Date":"2013-03-27T00:00:00","Height":0,"Final":0,"No":null,"Desc":"asfasf","Date":"2013-03-27T00:00:00","Height":0,"Final":0,"No":null,"Desc":"asfasfasf","Date":"2013-03-27T00:00:00","Height":2,"Final":0}”
//After Changes in the Model I am getting it in the required Array format:
//{"No":null,"Desc":"asfasfasfasfasfasfasfasfasfasfasfasf","Date":"2013-03-27T00:00:00","Height":0,"Final":null}
//{"No":null,"Desc":"etwetwetwetwet","Date":"2013-03-27T00:00:00","Height":0,"Final":0}
//{"No":null,"Des...
return Json(jsnRslt, JsonRequestBehavior.AllowGet);
}
でView
:
<div>
<script type="text/javascript">
$(document).ready(function () {
$("#grid").kendoGrid({
dataSource: {
type: "json",
serverPaging: true,
pageSize: 5,
groupable: true,
selectable: "row",
transport: { read: { url: "Records", dataType: "json"} }
},
height: 400,
scrollable: true,
sortable: true,
filterable: true,
pageable: true,
columns: [
{ field: "No", title: " No" },
{ field: "Desc", title: "Description" },
{ field: "Date", title: "Date" },
{ field: "Height", title: "Height" },
{ field: "Final", title: "Final" }
],
dataBound: function () {
this.expandRow(this.tbody.find("tr.k-master-row").first());
}
});
});
</script>
</div>
しかし、結局のところ、私が見ることができるのは空のグリッドだけです。また、JavaScript コンソールにエラーはありません。
