Custom DataControlField does not retain value after postback

I have a problem. I created a couple of custom DataControlFields because I need to display data that doesn't come from a DataSource on a DataGrid.
I managed to get the controls unto the GridView but I can't manage to solve a couple of issues.
My controls do not persist their values between postbacks. I have the markup sitting inside an UpdatePanel which I set to Conditional. I then configured my triggers, excluding those of the GridView. I also tried setting the UpdateMode to Always. I get the same behavior here.
Here is my markup:
<asp:UpdatePanel UpdateMode="Conditional" ID="reportchooserUpdatePanel" runat="server">
<ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="ddlMonth" EventName="Load" />
<asp:PostBackTrigger ControlID="ddlMonth" EventName="SelectedIndexChanged" />
<asp:PostBackTrigger ControlID="ddlYear" EventName="DataBinding" />
<asp:PostBackTrigger ControlID="ddlYear" EventName="SelectedIndexChanged
<asp:PostBackTrigger ControlID="GenerateReportsButton" EventName="Click" />
</Triggers>
<table class="ms-formtable">
<tr>
<td class="ms-formlabel">
<asp:Label ID="MonthYearLabel" runat="server" Text=""></asp:Label>
</td>
<td class="ms-formbody align-right">
<asp:DropDownList OnSelectedIndexChanged="ddlMonth_SelectedIndexChanged" AutoPostBack="true" runat="server" ID="ddlMonth" OnLoad="ddlMonth_Load">
<asp:ListItem Value="1">Januar</asp:ListItem>
<asp:ListItem Value="2">Februar</asp:ListItem>
<asp:ListItem Value="3">März</asp:ListItem>
<asp:ListItem Value="4">April</asp:ListItem>
<asp:ListItem Value="5">Mai</asp:ListItem>
<asp:ListItem Value="6">Juni</asp:ListItem>
<asp:ListItem Value="7">Juli</asp:ListItem>
<asp:ListItem Value="8">August</asp:ListItem>
<asp:ListItem Value="9">September</asp:ListItem>
<asp:ListItem Value="10">Oktober</asp:ListItem>
<asp:ListItem Value="11">November</asp:ListItem>
<asp:ListItem Value="12">Dezember</asp:ListItem>
</asp:DropDownList>
</td>
<td class="ms-formbody align-right">
<asp:DropDownList OnSelectedIndexChanged="ddlYear_SelectedIndexChanged" AutoPostBack="true" OnDataBinding="ddlYear_DataBinding" ID="ddlYear" runat="server"></asp:DropDownList>
</td>
</tr>
<tr>
<td style="width:100%;" class="ms-formbody" colspan="3">
<asp:GridView AutoGenerateColumns="false" ShowHeaderWhenEmpty="true" CssClass="grid-view" Width="100%" ID="gvProjects" runat="server">
</asp:GridView>
</td>
<td></td>
<td></td>
</tr>
<tr>
<td class="ms-formtoolbar align-right" colspan="3">
<asp:HyperLink Target="_blank" Font-Size="X-Small" ID="hlGembox" NavigateUrl="http://www.gemboxsoftware.com/spreadsheet/free-version" runat="server"></asp:HyperLink>
<asp:Button OnClientClick="AddNotification('Please wait...')" ID="GenerateReportsButton" runat="server" Text="" OnClick="GenerateReportsButton_Click" />
</td>
<td></td>
<td></td>
</tr>
</table>
</ContentTemplate>
</asp:UpdatePanel>
And here is the code of one of my custom DataControlFields. They are basically the same except for the controls they display:
class TemplateDropDownControl : DataControlField
{
SPList reportslist = ListItemHelper.GetReportsList();
protected void InitializeDataCell(DataControlFieldCell cell, DataControlRowState rowState)
{
string ID = Guid.NewGuid().ToString();
DropDownList list = new DropDownList();
list.ID = ID;
FillContentTypeDropDown(list);
cell.Controls.Add(list);
}
public override void InitializeCell(DataControlFieldCell cell, DataControlCellType cellType, DataControlRowState rowState, int rowIndex)
{
//Call the base method.
base.InitializeCell(cell, cellType, rowState, rowIndex);
this.InitializeDataCell(cell, rowState);
}
protected override DataControlField CreateField()
{
return new BoundField();
}
public string DataField
{
get
{
object value = base.ViewState["DataField"];
if (value != null)
{
return value.ToString();
}
else
{
return string.Empty;
}
}
set
{
base.ViewState["DataField"] = value;
this.OnFieldChanged();
}
}
public override void ExtractValuesFromCell(System.Collections.Specialized.IOrderedDictionary dictionary, DataControlFieldCell cell, DataControlRowState rowState, bool includeReadOnly)
{
DropDownList list = cell.Controls[0] as DropDownList;
ListItem selectedValue = list.SelectedItem;
if (dictionary.Contains(DataField))
dictionary[DataField] = selectedValue.Value;
else
dictionary.Add(DataField, selectedValue.Value);
}
private void FillContentTypeDropDown(DropDownList ddlContentTypes)
{
if (reportslist == null)
return;
SPContentTypeCollection cts = reportslist.ContentTypes;
ddlContentTypes.Items.Clear();
foreach (SPContentType ct in cts)
{
ddlContentTypes.Items.Add(new ListItem() { Text = ct.Name, Value = ct.DocumentTemplateUrl + ct.DocumentTemplate.Replace("~site", "") });
}
}
}
And lastly, here is the code where I add these to my page. I set the AutoGenerateColumns property of the GridView to false in markup:
private void BindDataGrid()
{
DataTable table = new DataTable();
table = new DataTable();
table.Columns.Add(ResourceHelper.LoadResource(ResourceName.ProjectnumberTableString));
table.Columns.Add(ResourceHelper.LoadResource(ResourceName.TemplateString));
table.Columns.Add(ResourceHelper.LoadResource(ResourceName.FileFormatString));
gvProjects.Columns.Clear();
gvProjects.DataSource = null;
//Fill DataTable here...
BoundField projectnumberField = new BoundField();
projectnumberField.HeaderText = ResourceHelper.LoadResource(ResourceName.ProjectnumberTableString);
projectnumberField.DataField = ResourceHelper.LoadResource(ResourceName.ProjectnumberTableString);
FileFormatCheckboxControl checkBoxControl = new FileFormatCheckboxControl();
checkBoxControl.DataField = ResourceHelper.LoadResource(ResourceName.FileFormatString);
checkBoxControl.HeaderText = ResourceHelper.LoadResource(ResourceName.FileFormatString);
TemplateDropDownControl dropDownControl = new TemplateDropDownControl();
dropDownControl.DataField = ResourceHelper.LoadResource(ResourceName.TemplateString);
dropDownControl.HeaderText = ResourceHelper.LoadResource(ResourceName.TemplateString);
gvProjects.Columns.Add(projectnumberField);
gvProjects.Columns.Add(dropDownControl);
gvProjects.Columns.Add(checkBoxControl);
gvProjects.DataSource = table;
gvProjects.DataBind();
}
Anybody know what I'm doing wrong here?
EDIT: Maybe I should be mentioning that I display the form in a Sharepoint modal dialog.

Ok I solved it another way since I had not idea why my problem kept happening. I just use a asp:Table now and generate the whole thing from code-behind. I have one method for this which I call on every page postback. It's important to note to call this method only from Page_Load. It didn't work when I called it from Page_Init.
Here is my code:
private void BindDataGrid()
{
GenerateReportsButton.Enabled = true;
reportsTable.Rows.Clear();
TableHeaderRow headerrow = new TableHeaderRow();
TableHeaderCell pnumberheader = new TableHeaderCell();
TableHeaderCell templateheader = new TableHeaderCell();
TableHeaderCell fileFormatHeader = new TableHeaderCell();
pnumberheader.Text = ResourceHelper.LoadResource(ResourceName.ProjectnumberTableString);
templateheader.Text = ResourceHelper.LoadResource(ResourceName.TemplateString);
fileFormatHeader.Text = ResourceHelper.LoadResource(ResourceName.FileFormatString);
headerrow.Cells.Add(pnumberheader);
headerrow.Cells.Add(templateheader);
headerrow.Cells.Add(fileFormatHeader);
reportsTable.Rows.Add(headerrow);
if (ddlYear.SelectedItem == null || ddlMonth.SelectedItem == null)
{
int index = reportsTable.Rows.Add(new TableRow());
TableCell cell = new TableCell();
cell.ColumnSpan = 3;
cell.Text = ResourceHelper.LoadResource(ResourceName.NoListItemsForMonthYear);
reportsTable.Rows[index].Cells.Add(cell);
GenerateReportsButton.Enabled = false;
return;
}
//Get items here
if (items.Count == 0)
{
int index = reportsTable.Rows.Add(new TableRow());
TableCell cell = new TableCell();
cell.ColumnSpan = 3;
cell.Text = ResourceHelper.LoadResource(ResourceName.NoListItemsForMonthYear);
reportsTable.Rows[index].Cells.Add(cell);
GenerateReportsButton.Enabled = false;
return;
}
else
InsertRowIntoProjectTable("Intern", "Intern");
List<string> processedReports = new List<string>();
foreach(SPListItem item in items)
{
if (item[Variables.projectNumberField].ToString() != "Intern" && !processedReports.Contains(item[Variables.activityProject].ToString()))
{
InsertRowIntoProjectTable(item[Variables.activityProject].ToString(), item.ID.ToString());
processedReports.Add(item[Variables.activityProject].ToString());
}
}
}
Then you can just read the data like this:
foreach(TableRow row in reportsTable.Rows)
{
//Important since foreach also iterates over headerrow
if (row.Cells[1].Controls.Count > 0 && row.Cells[1].Controls[0] is DropDownList)
{
string value1= row.Cells[0].Text;
string value2= ((DropDownList)row.Cells[1].Controls[0]).SelectedValue;
//do stuff with the data
}
}
If anybody still finds the answer to my specific problem above, feel free to add it. I will mark it as accepted once verified that it works.

Why is validating two random numbers during submission in a form not working

I have the following code-behind:
Random rndNum;
int inFirstOne, inSecondOne;
protected void Page_Load(object sender, EventArgs e)
{
rndNum = new Random();
int inFirst = rndNum.Next(1, 51);
int inSecond = rndNum.Next(50, 101);
lblFirst.Text = inFirst.ToString();
inFirstOne = inFirst;
lblSecond.Text = inSecond.ToString();
inSecondOne = inSecond;
}
public void ValidateForm(object sender, EventArgs e)
{
string strNum = tbValidation.Text;
int inCalc = inFirstOne + inSecondOne;
if (inCalc.ToString() == strNum)
{
lblIsValid.Text = "Correct";
}
else
{
lblIsValid.Text = "Please enter the correct result";
lblIsValid.ForeColor = Color.DarkRed;
}
}
ASP.net code:
...
<tr>
<td><h2>What is <asp:Label ID="lblFirst" Text="" CssClass="numGen" ClientIDMode="Static" runat="server" /> + <asp:Label ID="lblSecond" Text="" CssClass="numGen" ClientIDMode="Static" runat="server" />?</h2></td>
<td><asp:TextBox ID="tbValidation" ClientIDMode="Static" CssClass="tbTech" runat="server"></asp:TextBox> <asp:Label ID="lblIsValid" runat="server" /></td>
</tr>
<tr>
<td colspan="2" class="setRight">
<asp:Button ID="SubmitForm" ClientIDMode="Static" runat="server" Text="Submit" OnClick="ValidateForm" CssClass="btn" UseSubmitBehavior="false" />
</td>
</tr>
...
I am always seeing Please enter the correct result message.
How can I modify to ensure when the result is entered it works to validate the calculation from code-behind.

It's not clear how you're filling tbValidation but in any case unless you execute your page_load logic only if request it's not postback, variables inFirstOne and inSecondOnewill be overwritten on button click.
It seems you need to have this
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostback)
{
// do this only if it's the first request
rndNum = new Random();
int inFirst = rndNum.Next(1, 51);
int inSecond = rndNum.Next(50, 101);
lblFirst.Text = inFirst.ToString();
inFirstOne = inFirst;
lblSecond.Text = inSecond.ToString();
inSecondOne = inSecond
}
}

int inCalc = Convert.ToInt32(lblFirst.Text) + Convert.ToInt32(lblSecond.Text); worked.

model binding webform TryUpdateModel not Working

I have a simple formview and simple modelbinding in webform:
<asp:FormView ID="frm" ItemType="SabaDoor2.Models.Content" SelectMethod="frm_GetItem" UpdateMethod="frm_UpdateItem" DataKeyNames="Id" runat="server">

and in code:
Models.Model1Container _db = new Models.Model1Container();
protected void Page_Load(object sender, EventArgs e)
{
bindEvents();
lblResult.ForeColor = System.Drawing.Color.Green;
lblResult.Text = "";

}
public SabaDoor2.Models.Content frm_GetItem([System.Web.ModelBinding.QueryString("Id")]int? Id)

}
var result = TryUpdateModel(item);
if (ModelState.IsValid)
{
_db.SaveChanges();
}
}
public override void Dispose()
{
_db.Dispose();
base.Dispose();
}
tryUpdateModel return true but my model(description field) doesn't update
:(

I find out logical error:
i have to initialize BindItem.Name property instd of item.Name
Text='<%# BindItem.Description %>'

Your OnLoad() method only triggers during the first page load. The data needs to be rebound every time the page is changed. Try removing the if(!IsPostBack) from the Page_Load method and see if it works.

bind custom class array in repeater

I want to bind the CourseFee[] array to repeater.
I want to bind Amount and CourseFeeType.Descr in my repeater.
How do I bind it?

Sample Class
public class Order
{
public CourceFeeType FeeType;
public int Amount;
public int CourseFee;
public void AddFeeTypeDetails(CourceFeeType Fees)
{
FeeType = new CourceFeeType();
FeeType.Code = Fees.Code;
FeeType.Desc = Fees.Desc;
}
// Nested class
public class CourceFeeType
{
public String Code;
public String Desc;
}
}
Sample Form Load Code
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
List<Order> List = new List<Order>();
Order OrderObj = new Order();
Order.CourceFeeType Fees = new Order.CourceFeeType();
