Forms Data Controls :: Way To Change A ListView Into Insert Mode
Mar 18, 2010
way to change a ListView into Insert Mode when linkbutton is not part of the ListView? Basically I have a button at the top of my page and when the user clicks the button I'd like to put the ListView into Insert Mode. I'm assuming that it's not working currently because the button is NOT part of the listview Layout Template.
<asp:LinkButton ID="lnkMachines" Text="Create New Machines" CommandName="Insert" runat="server" onclick="lnkMachines_Click" />

I created a formview that I am using for data input (DefaultMode=Insert)
One of the objects I have is a text box (see below)
[code]....
When I click submit I get a message that I cannot insert a Null into the field IntershipNumAvailable. This makes sense since I made this field a required field in the database.
How do I get the form to recognize that the user selected item is the one I want to write to the database?
What changes do I need to make here? Do I need to make changes to my parameter list?
I use GridView & FormView to update a record. but when I click the "save" button, throw an except : FormView must be in the insert mode to insert a record. The record has been updated success, and I didn't change the mode of the FormView, how this error comes?
When i run the following code i get an error when gridview changes mode to Edit. stating that you can't change string to decimal!
To get around the occurance i want to disable code when in Edit mode or resolve another way?
GridView1_RowDataBound For Each row As GridViewRow In GridView1.Rows Dim cell As TableCell = row.Cells(7) Dim invoicetotal As Decimal = CDec(cell.Text)
I am simply trying to change the listView template based on a value in the listview data. I do have this displaying the information correctly. Except when I try to change the item template based on a value in the listview. My code is below ....
Student Name: John Exam Grade MidTerm1 A MidTerm2 B
For this, I defined a class 'Student' that has the properties StudentName[String] and Exams [a list of ExamGrade objects which has the Exam and Grade properties]. And I am using nested listviews to display the data. Here is the markup for the ListViews:
[Code]....
And the StudentInfo class looks like this:
[Code]....
And Exam class has just two properties.
Now the issue is that I have to press the Edit button [link button] twicw to get the EditItemTemplate. Even then I would get the blank textboxes. So what should I do to make the EditItemTemplate appear on the first click and the TextBoxes to appear with the existing data?
I have a listview whit "select" button.... i want when i click this button the listview should show a Delete buttonn What is wrong in my code ..i press select button there is noting hapning??
I have a basic list view, in the edit mode I have a dropdown list, and a checkbox, I want it so that if you choose "yes" from the drop down box the check boxs becomes enabled. I know I need to find the control but I keep getting object refrence error with this code.
[Code]....
the listview renders its layout / item template fine but when I click on edit to send it to edit mode it fails to find the dropdownlist ddlQA1YNM which is a bit ironic cause its the ddlQA1YNM that is making the call to ddlQA1YNM_ondatabound. Now it could be with the fact its on the databound stage. Not sure how that plays into the stack. I call ondatabound to determine what the dropdownlist value is and set the enabled status according on the load into edit mode.

Formview1 datasource ID is SQLTest. When I click New on the form and go into insertmode, is there an easy way to auto file textboxID to the value of the NextIDNumber field ( field 9) from SQLTest datasource?
How do I set the value of a field in a detailsview to the selectedvalue of a gridview on the same page? I am also trying to set today date as value of another field in the detailsview as well as UserID. I wrote the following codebehind for the date setting:
TextBox tb = (TextBox)DetailsView2.FindControl("TextBoxCreDate"); tb.Text=System.DateTime.Now.ToShortDateString(); TextBoxCreDate is a template field in my DetailsView.
Unfortunately, I get a Object reference not set to an instance of an object. Error message.
I have a "report" the users can run it basically creates a simple gridview. In the gridview the user can click on a claim ID. The claim id is then passed via url querystring to a claim management page. The claim management page uses a listview to display the various claims and allow users to edit them. I want to use the claim id passed in the url to locate the listview row to open in edit mode, so the user can make changes / alterations to the claim.
I guess I'm not sure exactly how or where to do what I need.
First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.
I've tried using the ModeChanging (and ModeChanged) event: Dim dv As TextBox = CType(DetailsView1.FindControl("txtNew"), TextBox) If (e.NewMode = DetailsViewMode.Insert) Then ....
However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.
So, I'm trying to use form view in insert mode on a dedicated aspx page. So when a user clicks "Add New" from the main GridView page, it will take the user to an Insert.aspx page that will be in Insert mode ready to collect information.
Here's what I have so far, and all I get is a blank page when I try to run it.
I have a FormView at the very bottom of the page in insert/edit mode. When I click insert/update button, the whole page reload and the pointer does not keep within the Formview but go to the very top of the page far away from the desired FormView.
What can I do here to prevent cursor going outside the Formview ? Is it I can use update panel ? What and where I should use the tags ? Or there are other better way ?
I have a template field in datagrid. The field shows in insert mode. I do not want to show it because it is a thumbnail to an attachment. The regular bound fields have a setting "Insert Visible" which could be set to false - that is supposed to hide them in insert mode. The template field has no such thing. I have even tried to put Insert Visible = False in to the source but to no avail.
My definition of the template field looks like this:
I have a gridview and detailsview that are connected. When I delete records everything works fine except when I delete the last record in the gridview. I want the detailsview to revert to insert mode when I delete the last row in the gridview. Instead the detailsview shows up blank. I want to show the detailsview in insert mode after last row in grid has been deleted? How can do I this?
A DetailsView in Insert mode has all fields cleared after events such as the following:
1. Clicking New. 2. Clicking Cancel. 3. Clicking Insert (if the default mode is Insert).
I have some fields linked to ViewState and they are populatd at PreRender event handler. I am wondring if there is a single place where all relevant ViewState elements can be cleared instead of doing this in all possible relevant handlers such as ItemCreated, ItemCanceled, ItemInserted, etc.
