Hi,
I am using WCF Service to get data from Entity Framework, I am getting the following error while I am trying either trying to get data from service or while converting the returned data into jSon, its a huge list with more than 200K records each record might be of size 20 columns.
public ActionResult FDER_Read([Kendo.Mvc.UI.DataSourceRequest] Kendo.Mvc.UI.DataSourceRequest request)
{
using (ReportsClient reportclient = new ReportsClient())
{
CommonFunctions.IgnoreCertificationErrors();
try
{
var data = reportclient.GetFDER(GetCurrentFiscalPeriod(), GetCurrentUser());
var serializer = new JavaScriptSerializer();
var result = new ContentResult();
serializer.MaxJsonLength = Int32.MaxValue;
result.Content = serializer.Serialize(data.ToDataSourceResult(request));
result.ContentType = "application/json";
return result;
}
catch (Exception ex)
{
throw ex;
}
}
}
I have set the bindings to support max values I am not sure what am I missing?
Here is my ASP.Net MVC applications Web Config

The size of the returned object is: 96479088 and number of records are: 196411
I am not understanding what am I missing. I defined the Service and End point behaviors, any help would be greatly helpful, thanks in advance - please.
Thanks,

That's a lot of data to return in a single request. But are you sure the error is caused by the size of the response, and not something else? I couldn't see the error details in your question.

I have a markup page that was using CommandField delete button. This was later replaced with regular button control.
Code:
<table>
<tr>
<td>
<asp:gridview ID="Gridview1" RowStyle-Wrap="false" gridlines="None" CssClass="responsiveTable1" runat="server" ShowFooter="true" AutoGenerateColumns="false" OnRowDeleting="Gridview1_RowDeleting">
<Columns>
<asp:BoundField DataField="RowNumber" Visible="false" HeaderText="Row Number" />
<asp:TemplateField HeaderText="Name">
<headerstyle horizontalalign="Left" />
<ItemTemplate>
<asp:TextBox ID="txtsourcename" placeholder="Name...(e.g, Jane Doe)" runat="server" style="width:375px;" AutoPostBack="true" class="form-control textClass" OnTextChanged="txtsourcename_TextChanged"></asp:TextBox><br />
<asp:CheckBox ID="grid1Details" ClientIDMode="Static" runat="server" Checked="false" AutoPostBack="true" OnCheckedChanged="Grid1CheckChanged" /><span style="color:#ff0000">*Check this box if N/A</span>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Address">
<ItemStyle HorizontalAlign="Left"></ItemStyle>
<ItemTemplate>
<asp:TextBox ID="txtsourceaddress" placeholder="Address..." runat="server" style="width:375px;" class="form-control textClass"></asp:TextBox><br /><br />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:Button ID="ButtonAdd" runat="server" Text="Add"
onclick="ButtonAdd_Click" CssClass="grvAddButton" /><br /><br /><br>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:Button ID="sourceDelete" runat="server" Text="Delete" CommandName="Delete"
CssClass="grvDelButton" OnClientClick="return confirm('Are you sure you want to remove this row?')" /> <br /><br /><br />
</ItemTemplate>
</asp:TemplateField>
<%-- <asp:CommandField ShowDeleteButton="True"><ControlStyle CssClass="grvDelButton" /></asp:CommandField>--%>
</Columns>
</asp:gridview>
</td>
</tr>
</table>
The delete button is used to delete any additional / unwanted rows created in dynamically generated row in GridView.
Since the commandField delete button was replaced, the VB the engineers the delete action is now throwing an error:
Unable to cast object of type 'System.Web.UI.WebControls.TemplateField' to type 'System.Web.UI.WebControls.CommandField'
Does anyone know how to modify this to reflect the button control ID used in markup instead of CommandField?
Protected Sub GrvSource_RowDataBound(sender As Object, e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.Header Then
If e.Row.RowIndex = -1 Then
DirectCast(DirectCast(e.Row.Cells(4), DataControlFieldCell).ContainingField, CommandField).ShowDeleteButton = False
End If
Else
If Convert.ToInt32(ViewState("rowIndex" & 0)) = e.Row.RowIndex Then
DirectCast(DirectCast(e.Row.Cells(4), DataControlFieldCell).ContainingField, CommandField).ShowDeleteButton = True
End If
End If
End Sub
Thank in advance

You don't need to worry about the header row, since the ItemTemplate doesn't apply there.
So that just leaves the Else block, which is toggling the button's visibility based on a condition. You can do the same thing with a data-binding expression.
Something like this should work:
<asp:Button ID="sourceDelete" runat="server"
...
Visible='<%# Convert.ToInt32(ViewState("rowIndex" & 0)) = Container.DisplayIndex %>'
/>

Hi Richard,
You always come up with the simplest, easy to understand solutions.
Thank you very much.
As I understand, I need to trash the VB portion of the code and just use the Visible='<#...))
If so, the delete button is still visible.
It needs to be invisible until the Add button is clicked.

How can I create an organisational chart and be able to click it and see information on it?
|
|
|
|
|
I suggest you look a Visio for drawing the organizational chart. Then consider using VBA which can be invoked on a shape to get more detailed information.
Visio VBA reference
Good luck

Are you authenticating completely out of band with ASP.NET? I'm trying to figure out how you would apply privileges in that scenario, and failing.

No. If you want some code written then you need to write it. Alternatively you could use Google or Bing and do some searching for yourself.

I have developed a tabular UI with webgrid. i am showing student information through webgrid. i am showing multiple checkboxes for hobbies in each row of webgrid. when i select hobbies and click submit button then i saw hobbies selection is not going to action.
i guess there is my mistake in view model class design. please have a look at my code and tell me which area i need to change in code.
i want all hobbies should go to action when i click submit button and selected hobbies also should post to action for each student. a student may have multiple hobbies selected.
here is my viewcode
@model MVCCRUDPageList.Models.StudentListViewModel
@{
ViewBag.Title = "Index";
}
<h2>Student View Model</h2>
@using (Html.BeginForm("Index", "WebGridMoreControls", FormMethod.Post))
{
var grid = new WebGrid(Model.Students, canSort: false, canPage: false);
var rowNum = 0;
var SelectedHobbies = 0;
<div id="gridContent" style=" padding:20px; ">
@grid.GetHtml(
tableStyle: "table",
alternatingRowStyle: "alternate",
selectedRowStyle: "selected",
headerStyle: "header",
columns: grid.Columns
(
grid.Column(null, header: "Row No", format: item => rowNum = rowNum + 1),
grid.Column("ID", format: (item) => @Html.TextBoxFor(m => m.Students[rowNum - 1].ID, new { @class = "edit-mode" })),
grid.Column("Name", format: (item) => @Html.TextBoxFor(m => m.Students[rowNum - 1].Name, new { @class = "edit-mode" })),
grid.Column("Country", format: (item) =>
@Html.DropDownListFor(x => x.Students[rowNum - 1].CountryID,
new SelectList(Model.Country, "ID", "Name", item.CountryID),

I think your JSON data needs to start and end with curly braces, not square brackets. So it should be something like:
{
[
{
"name": "chris",
"ic": "111111-11-1111",
"phone": "011-1111111",
"address": "street 01",
"gender": "male"
},
{
"name": "carolyn",
"ic": "222222-22-2222",
"phone": "012-2222222",
"address": "street 02",
"gender": "female"
}
]
}
And you may also need a label in front of the main array to identify it.

If you look at the documentation[^], or google for any example on-line, you'll see the type you supply DeserializeObject is the type you want the json to be converted to. You are saying you want the json converted to a string which makes no sense as it is already a string. So you're confusing the json parser.
Again referring to the documentation you need to create a class that represents your data and deserialise to that. So create a class like
public class Person
{
public string name { get; set; }
public string ic { get; set; }
public string address { get; set; }
public string gender { get; set; }
}
as your json is an array of these objects you was to convert it to a List<Person>
List<Person> obj = JsonConvert.DeserializeObject<List<Person>>( ... );

i want to update a local json file (add & remove) at server side, can anyone show me how to do it?
I pass a id parameter to determine which record i want to remove from client side to server side using ajax
$.ajax({
type: "POST",
url: "WebForm1.aspx/remove",
data: "{id:" + id+ "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess,
failure: function (response) {
alert(response.d);
}
});
after that i had no idea how to code to modify the local file.
[System.Web.Services.WebMethod]
public static void remove(string id)
{
}
