Web Forms :: Nested Formview - Link Parent Formview Control In Editmode With Child Formview Control In Insertmode
Apr 8, 2010
i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)

by default, my formview loads up to Editmode and it looks like this:
[Code]....
My Page_load looks like this:
[Code]....
Problem is if binding is not ran during postback here, buttons on the ItemInsert mode DO work, but the button on the ItemEdit mode DON'T work. However, if I don't bind the fv1 here during postback, controls will not load on the formview ItemEdit mode and databinding will not occur.

I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?

I've got a FormView control for which I'm Viewing, Inserting and Updating to a MS SQL Database.
Instead of adding a SqlDataSource control to the page, I've created it in the code behind and declaring the properties/attributes for it during Page_Load.
At the moment, everything is bound and working fine, but I'm having an issue Databinding to the child controls in my FormView with parameters set in the code behind.
This is where I'm at.

So, I need to be able to bind the DS.InsertParameters.Add("PageTitle", ---) with the txPageTitle control in the Insert Template, same with the PageURL to txPageURL. Is there any easy way to do this from the code behind? I can't seem to find a way to add a parameter without needing to assign it a value.

since APS.Net 4.0 I have a curious problem with an event.
There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.
But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.
The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.
[Code]....
Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:
Is this a known change or a bug of ASP.Net 4.0?

I have a formview that I am adding and editing items. I need to have a lookup button besides a textbox so I can click the button and show a webgrid listing items with their descriptions. Select one and enter the data in the formview control. I know how to put the data in the formview control with the FormView.FindControl method. But how can I add a lookup? Can I do this with a popup panel? And on the postback update the textbox control?

I want to preset the value of a textbox within a databound formview. Tried it within codebehind on onModeChanging and onItemInserting. Method onModeChanging was fired but the textbox.text shows not the expected text. Method onItemInserting was not fired at all.
Thought to use inlinecode like
<asp:TextBox ID="txt_CREATOR" runat="server" CssClass="txtTask" Text="<%=giSessionHandling.UserName %>"/>
in the aspx but don't know how to ...
<asp:FormView
ID="frmViewDetail"
runat="server"
DataSourceID="dsrcDetail"
DataKeyNames="TASK_ID"

I have a simple FormView (fvDespatchPart) which updates the status of an order and it's despatch date; the despatch date being retrieved from a textbox (txtRentalDespatchDate)
held within the FormView. The FormView's DefaultMode is set to Edit.
I have been trying to set the default entry for txtRentalDespatchDate to today's date in the code behind, using:
Dim dtNow As Date = Today()
Dim txtRentalDespatchDate As Webcontrols.Textbox = fvDespatchPart.FindControl("txtRentalDespatchDate") [code].....
I have had no trouble doing this in the past with FormViews whose default mode is set to Insert or Item, but in Edit mode it just does not seem to want to co-operate. I have read a few help posts, and have tried:
Putting that code in LoadComplete, PreRender, PreRenderComplete Page events, as well as the FormView's databound event. I've also tried nesting it within a ...
If fvDespatchPart.CurrentMode = FormViewMode.Edit Then
End If
... just to make sure if is in the right mode.
Nothing yet has resulted in anything but the same old error.

I am attempting to show/hide a control (txtInpatientType) when a user views individual records on a FormView (frmData) depending on the value stored in another control (txtPatientType). For example, if txtPatientType.Text = "Inpatient" then txtInpatientType.Visible needs to be True. Very simple code follows.
[Code]....
txtPatietType and txtInpatientType are both ReadOnly. txtInpatientType.Visible = false by default.

i create a composite control as can be seen in code below, and add this control to webform, assign FormView1 to the HeaderControlName property, Run the page, the system will generate parse error message :
Cannot create an object of type 'System.Web.UI.WebControls.FormView' from its string representation 'FormView1' for the 'HeaderControlName' property. However, if i don't assign FormView1 in design screen and manually (through coding) assign FormView1 to the custom control on init, it works as expected.
custom control
public class CmdTest : CompositeControl
{
public virtual FormView HeaderControlName
{
get
{
object oObject = ViewState["HeaderControlName"];
return (oObject == null) ? null : (FormView)oObject;
}
set
{
ViewState["HeaderControlName"] = value;
}
}
protected override void CreateChildControls(
{
Controls.Clear();
Button xx = new Button();
Controls.Add(xx);
}
}
webpage.aspx (assign FormView1 in design time, it will generate error)
<Utils:CmdTest ID="CmdTest1" runat="server" HeaderControlName="FormView1" />
webpage.aspx (didn't assign FormView1 in ASPX, but assign it on Init Code, it works)
<Utils:CmdTest ID="CmdTest1" runat="server" oninit="CmdTest1_Init" />
Webpage.aspx.cs
protected void BsCmdTest1_Init(object sender, EventArgs e)
{
CmdTest1.HeaderControlName = FormView1;
}

I have a formview with an insert item template. I have added two dropdown controls that are databound to two different database tables to this insert template. However, when I click the 'InsertQuery' for the Accessdatasource neither of these controls are available as 'Parameter source options'.Out of interest, if I take these dropdown controls out of the formview and put them on the page they then become available to use.

I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.

I have a calendar control where a user selects a date and then inputs info into a FormView control. Underneath the FormView is a GridView that shows all data from the SelectedDate on the calendar control. However, when the date is selected, all the information from the table ( from all dates ) is displayed.

I use a GridView control to select the row to display within the FormView. The FormView contains a RadioButtonList to facilitate the selection of one of its values. My C# codebehind contains a "selected_index changed event to grab the values from any of the modified FormView controls. My problem is that it is not picking up the selected radio button. Here's some code:

For example, if the dropdown was not in the FormView I would simply use...

Instead of usng FormView with SQLDataSource control, I like to use it with LINQ-to-SQL. For example, can I write my own LINQ to SQL for Edit and Update? Will FormView control work in this way?

I have a formview with an entitydatasource. I am using a fileupload control in the formview to upload file to a folder. The file upload works fine. The formview is bound to a table x with a field for storing the filepath. I want the uploaded filepath to be stored in that field after fileupload. My html is as follows. I tried setting the textbox txtImageURI to the filepath in Formview_ItemInserting event, but the data did not get store.
<asp:FileUpload
ID="fupldEvent"
runat="server"
/>
<asp:TextBox
ID="txtImageURI"
runat="server"
Text='<%#
Bind("ImageURI") %>'
Visible="false"
