C# - Set The One Template For Edit/insert And View In My Custom FormView Control
Aug 17, 2010
I would like to set the one template for edit/insert and view in my custom FormView control . But i got these odd exception Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.Table'.
public class CustomFormView : FormView
{
[PersistenceMode(PersistenceMode.InnerProperty), TemplateContainer(typeof(FormView), BindingDirection.TwoWay)]
public IBindableTemplate FormTemplate { get; set; }
protected override void OnInit(EventArgs e)
{
ChangeMode(FormViewMode.Edit);
if (FormTemplate != null)
{
if (CurrentMode == FormViewMode.Edit)
{
FormTemplate.InstantiateIn(this);
}
}
base.OnInit(e);
}
}
edited :
in the first step , I created the new user control and added a formview ("FV")
public partial class Form : UserControl
{
private IBindableTemplate _template = null;
[PersistenceMode(PersistenceMode.InnerProperty),
TemplateContainer(typeof(FormView), System.ComponentModel.BindingDirection.TwoWay)]
public IBindableTemplate FormTemplate { set;get }
protected void Page_Init()
{
if (FormTemplate != null)
{
FV.InsertItemTemplate = FV.EditItemTemplate = FormTemplate;
if (!IsPostBack) FormTemplate.InstantiateIn(FV);
}
}
}
Now , I want to convert this user control to web control.

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

I am having with an AJAX control. I have a master page nested into another master page. On the nested master page, I have a gridview control. I want to place a text box and calendar extender into the editing template. However, I keep getting run time errors and cannot seem to sort out the problem. Here are the code samples and error messages I am receiving:
<asp:TemplateField HeaderText="EffectiveDate">
<EditItemTemplate>
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"></asp:ToolkitScriptManager>

I keep getting a null reference when I try to access a listbox inside the EditItemTemplate of a formview. I check the mode before accessing the control (Formview1.CurrentMode) to make sure it is in edit mode and even set it manually to edit mode again! But formview1.findcontrol("blah") returns null. Formview1.EditItemTemplate does not have a FindControl method, not sure what else to try.

After I use FormView in InsertMode and the record is added, I want it to switch directly to EditMode.
I assume I would place this command in this action:
protected
void FormView1_ItemInserted(object sender,
FormViewInsertedEventArgs e)
However, I can't find the correct command to issue.

I have a formview with both edititem template and item template as following:
<asp:FormView ID="PFTFormView" runat="server"
DataKeyNames="PFTId"
EnableModelValidation="True" Width="90%"
OnItemUpdating="PFTFormView_ItemUpdating"
onmodechanging="PFTFormView_ModeChanging" >
<EditItemTemplate>
<table>
<tr><td class="style1">PFTId</td><td class="style3"><asp:Label ID="lblPFTId" runat="server" Text='<%# Eval("PFTId") %>' /></td></tr>
<tr><td class="style1">Last Name</td><td><asp:TextBox ID="txtPFTLastName" runat="server" Text='<%# Bind("PFTLastName") %>' Width="200px" /></td></tr>
<tr><td class="style1">First Name</td><td><asp:TextBox ID="txtPFTFirstName" runat="server" Text='<%# Bind("PFTFirstName") %>' Width="200px" /></td></tr>
<tr><td class="style1">Home</td><td><asp:TextBox ID="txtPFTHome" runat="server" Text='<%# Bind("PFTHome") %>' Width="200px" /></td></tr>
</table><br />
<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True"
CommandName="Update" Text="Update" />
<asp:LinkButton ID="UpdateCancelButton" runat="server"
CausesValidation="False" CommandName="Cancel" Text="Cancel" />
</EditItemTemplate>
<ItemTemplate>
<table>
<tr><td>PFTId</td><td><asp:Label ID="lblPFTId" runat="server" Text='<%# Eval("PFTId") %>' /></td></tr>
<tr><td>Last Name</td><td> <asp:Label ID="lblPFTLastName" runat="server" Text='<%# Bind("PFTLastName") %>' /></td></tr>
<tr><td>First Name</td><td><asp:Label ID="lblPFTFirstName" runat="server" Text='<%# Bind("PFTFirstName") %>' /></td></tr>

</table><br />
<asp:LinkButton ID="EditButton" runat="server" CausesValidation="False"
CommandName="Edit" Text="Edit" />
</ItemTemplate>
</asp:FormView>
on my code behind, I have:
Sub PFTFormView_ItemUpdating(ByVal sender As Object, ByVal e As FormViewUpdateEventArgs)
Dim PFTObj As New PFT
Dim PFTDST As New Data.DataSet
Dim newPFTLastName As String = DirectCast(PFTFormView.FindControl("txtPFTLastName"), TextBox).Text
Dim newPFTFirstName As String = DirectCast(PFTFormView.FindControl("txtPFTFirstName"), TextBox).Text
PFTObj.PFTLastName = newPFTLastName
PFTObj.PFTFirstName = newPFTFirstName
PFTObj.PFTHome = DirectCast(PFTFormView.FindControl("txtPFTHome"), TextBox).Text
If PFTObj.UpdatePFT(Session("PFTId")) Then
Me.lblErrorMessage.Text = "PFT Update Successfully"
Else
'
Me.lblErrorMessage.Text = "PFT Update UnSuccessfully"
End If
PFTDST = Nothing
PFTObj = Nothing
end sub
The problem is:
PFTObj.PFTLastName = newPFTLastName
PFTObj.PFTFirstName = newPFTFirstName
PFTObj.PFTHome = DirectCast(PFTFormView.FindControl("txtPFTHome"), TextBox).Text
are not returning the updated value from the form.

I am trying to change the textboxes in the FormView insert template to dropdownlists but they keep setting the parameters to null. Here's what I have:
[Code]....
In Page_Load
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2010", "2010"))
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2009", "2009"))
and in the SqlDataSource
InsertCommand="INSERT INTO [tblSurvey] (... [YearOfQualification] ...) VALUES ( ... @YearOfQualification ... )
And in insert parameters:
<asp:Parameter Name="YearOfQualification" Type="Int16" />
And the insert fails with YearOfQualification as null. If I sue the standard textbox:
<asp:TextBox ID="YearOfQualificationTextBox" runat="server"
Text='<%# Bind("YearOfQualification") %>' />

I have a web form for handling invoices which has a form view. When I'm in insert item template, I need to have various fields. Some of them are contract number, invoice number, register date and other that are easy to handle. But there is a dropdown list related with a table of prices (the table has price name, price initial payment, number of payments, amount of month fee and so on). So, when the dropdown is selected, fields related with price should get their values from price table, and then the user decides to keep them or type in new values. How can I get it done? Should I use a Dynamic populate extender or type all the code behind using SelectedIndexChanged method to populate price related controls?

I am using C#, Object Data Source, formview and a BLL. I have two drop down lists and two data sources. One populates the other. Drop down list #1 populates Drop Down list # 2 based on its selection . Drop down list # 1 is populated with DataSource #1. Forview is using DataSource #3 to send the ietms. When I add: SelectedValue='<%#Bind("Make_ID") %>', I get the error below:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control
I have seen a solution online but it is using LINQ and I am not familiar with it. I need to find the selected value of the drop down lists.

I'm using an edittemplate to handle both editing and inserting for a Formview. In Insert mode, the Identity parameter is not needed (and cannot be used in the parameter list). In Edit mode, I need the bound value to know which record to update. So, what I tried to do is set the Text property in the OnDataBinding method.
[Code]....
The result is that the field is bound for Insert anyway, shows up as a parameter, and my insert statement fails (since this extra field messes up the field order of the parameters). Plus, it is always null in Insert mode by definition.
Is the OnDataBinding method too late to clear the property? If so, where can I do this, since PageLoad is too early (the template has not loaded yet and I cannot Findcontrol the field. Or is there a better way to handle all this?

I have an edit template on gridview which opens a text box and button with a custom validator .
On button press I have to validate the text in edit item template with a text field in gridview row template.
I am having a hard time fetching the data of the edit template textbox. Even though both custom validator and textbox are in same edit item template but intellisense is not picking it up.
Also the custom validator server_validate event is using "object source" instead of "object sender"
How do I fetch the edit item template text for comparison
I am doing this as
protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
{
GridViewRow gvrow = (GridViewRow)(source as Control).Parent.Parent;
int index = gvrow.RowIndex+1;
// TextBox txttmp=(TextBox)
Label lbl = (Label)gvComp.Rows[index].FindControl("lblSecShare");
decimal CSh = Convert.ToDecimal(lbl.Text);
}

I've created a class which extends System.Web.Mvc.ViewPage which I want to be the default class each view inherits from. This is controlled by the "pageBaseType" attribute in the "pages" element in the web.config file in each Views folder. If I add a Views folder in Visual Studio, it creates the web.config.
I would like to change the template it uses to do this to use a different value for pagBaseType. I assume there is a template somewhere I could modify, but I don't know where it is.

I'm using a formview in Insert mode with an AccessDataSource. I want to switch to readonly mode upon insertion to let the user confirm the input worked, then give them the option to insert a new record. If I set the DefaultMode to Insert, then after the first record is inserted, I get a new blank insertion form (no confirmation). If I set the DefaultMode to ReadOnly, after insertion, I get a blank form (presumably because I am not on the record just inserted).
How do I get the just inserted record to display? If I need to set the ID of the formview to the just inserted record OnInserted, how do I get that given I'm using an AccessDataSource?
