Forms Data Controls :: ObjectDataSource Cannot Access GridView Control Inside FormView
Apr 16, 2010
Basically as the title of this thread states, I have a FormView that has a GridView inside it and my ObjectDataSource that populates this grid cannot access the Grid.
The Control Id needs to be the name of the Grid I want to access, however through the 'wizard' the Control parameter drop down cannot 'see' the grid I need, only the FormView that is in.
I have tried numerous ways to get round this and am struggling now..
I've tried the following...
ControlID="FormView.GridView1"
ControlID="FormView.FindControl("GridView1")
ControlID="<%= GetNameOfGrid %>"
and numerous other attempts that also failed that I now cant remember...
I have an ObjectDataSource giving me data similar to: OrderNumber OrderDate OrderValue OrderItems The first three are simple data types and the last has multiple occurrences of another class: OrderLineNumber OrderItem OrderQuantity The ObjectDataSource will only contain one row (which might make things simpler). So, there will be one OrderNumber, OrderDate and OrderValue; and then several occurrences of OrderItems (each containing OrderLineNumber, OrderItem and OrderQuantity).
I am displaying OrderNumber, OrderDate and OrderValue in the FormView - that work's fine, as expected. I have placed a GridView within the FormView and am failing miserably to get it to bind to OrderItems. I have tried the obvious things like specifying "odsWhatever.OrderItems" as the DataSourceID for the GridView, but to no avail.
I trying to save clients IP address who are submitting the data on my website. I have downloaded an example and implemented. That scrip displays IP address on the webpage. I can submit this to sql table through code behind. Now I want to use same script in FormView and I am unable to bind this with the text box as it is showing an error "The name IPaddress does not exist in the current context". My code is as under :

How to write code in vb.net to control the Dropdown which is inside FormView EditItemTemplate. FormView named "frmFaultsReg" DetailsView named "lstStatus" Actually what i want to do that there is a textbox inside FormView EditItemTemplate and ItemTemplate to insert Closing date. lstStatus has a value PENDING and CLOSED. If a user select CLOSED from lstStatus then the date textbox named "ClrDateTimeTextBox" should show current date time and to insert into database and if user again selects PENDING from lstStatus then the date textbox should show empty. I think the postback of lstStatus should work but lstStatus is inside the FormView thats why I am unable to hook it.
I'm using a FormView which has odsMain as the datasource. I am also using a dropdownlist which is being populated with objectdatasource odsddl.
I'd like to set the selectedvalue of the dropdownlist with the value contained in odsMain (the current record value for it). Is there any way this can be done?
I have a FormView bound to an ObjectDataSource that is bound to a business logic object. The business logic object has a Readonly field called "Id". When I try to update the formview, I get the following error message: The 'Id' property on the type specified by the DataObjectTypeName property in ObjectDataSource 'ObjectDataSourceNewsArticle' is readonly and its value cannot be set. How do I get the ObjectDataSource or the FormView to recognise that the id field is readonly, and to not try to update it?
I'm having a problem with a FormView control that I have bound to an ObjectDataSource. The problem is that the FormView control is not automatically filled in with the public properties of the object linked by an ObjectDataSource control when I select refresh schema. Everything compiles and I can add fields manually, but there are a lot of properties in the class and I do not want to deal with adding all the fields by hand. It's not the end of the world of course if I have to add them manually, but I'm bothered more by the fact that it doesn't act the other formviews.
Has anyone ever experienced a problem like this? I have other objectdatasource controls with other formviews that properly refresh their schemas. I noticed that in the objectdatasource control that is giving me problems, the DataObjectTypeName field is not automatically set as it is in the others. However, after adding it manually it still doesn't refresh the schema. I'm using Visual Studio 2010. Defined in .aspx page:

The SPFModuleBLL class contains the GetModule2() method which is shown here:
I have an object data source control. and to insert the control I add the object to the database then call databing on the gridview the DataSource control is bound to.
My question is - how would I know where the newly added row is? I can'y go by id, because the dbase creates the id.
I'm thinking maybe last data key, but based on the sort that would be accurate.
I need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void
rptCAP_ItemDataBound(object sender, RepeaterItemEventArgs e) { LinkButton lnDel = (LinkButton)rptCap.FindControl("lnkDelete"); lnkDel.Enabled = false; //<<<<< this is where the error occur }
I was able to get the formview bound to the objectdatasource, it works great for the first record, but when i select the next record it gives me error below is all my code, if there is something else that i need to post .
I have a checkbox and a panel inside of a FormView control, and I need to access them from the code behind in order to use the checkbox to determine whether or not the panel is visible. This is the code that I originally used, but since I put the controls inside of the FormView, it no longer works.
Protected Sub checkGenEd_CheckedChanged(ByVal sender As Object, _ ByVal e As System.EventArgs) If checkGenEd.Checked = True Then panelOutcome.Visible = True Else panelOutcome.Visible = False End If End Sub
I've started to figure this out based on other questions I looked up on here, but all of them were in C# instead of VB, so this is as far as I got:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound If FormView1.CurrentMode = FormViewMode.Edit Then End If End Sub
So yeah I'm not sure exactly how to finish it. here's my code now:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound If FormView1.CurrentMode = FormViewMode.Edit Then CheckBox checkGenEd = formview1.FindControl("checkGenEd"); Panel panelOutcome = formview1.FindControl("panelOutcome"); End If End Sub
It's also saying that checkGenEd and panelOutcome are not declared. I changed my code to this but it still doesn't work:
Protected Sub FormView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.DataBound If FormView1.CurrentMode = FormViewMode.Edit Then Dim checkGenEd As CheckBox = FormView1.FindControl("checkGenEd") Dim panelOutcome As Panel = FormView1.FindControl("panelOutcome") If checkGenEd.Checked = True Then panelOutcome.Visible = True Else panelOutcome.Visible = False End If End If End Sub
There aren't any errors anymore, but nothing happens when I click the checkbox. I think there needs to be some kind of event to trigger it but I don't know how you can put an event handler inside of an event handler.
I have gridview in my page that users can edit their data in gridview... and in this gridview I define label that I want when users click on Edit button it change label3.text:
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.
I have a dropdownlist outside the gridview control. My griview control also have dropdownlist in the first column. I want to populate the dropdownlist inside the gridview control for all rows when the selected item is changed in the outside dropdownlist.
I have a RadioButtonList control inside of a nested ListView control InsertTemplate. I need a way to access this control in the nestedListView_ItemInserting method.
Based on the selection of SchoolID in listviewSchools, the ListviewStudents will be filled with the data.
SchoolIDLabel is in the ItemTemplate of the ListviewSchools. The following works for insertitemtemplate
Dim txtTitle As TextBox = CType(ListView1.InsertItem.FindControl("txtTitle"), TextBox), but i can not Access a control inside the ItemTemplate of a listview.
I have a GridView inside a repeater, and for all the GridView events such as ItemDataBound, etc. I can't just use the same because it doesn't recognize it. I know I have to use FindControl and type in the ID, but how?
