Forms Data Controls :: Open An Item In Listview In Edit Mode On Page Load?

Apr 20, 2010

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.

Forms Data Controls :: Way To Select Item In A ListView - How To Get Appropriate Index Number

Sep 7, 2010

I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.

Forms Data Controls :: Validating Page With Listview Edit Item And Insert Item Templates Are Both Present

Aug 9, 2010

I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.

The InsertItem Template is in the first position, making it easy to insert a new record.

And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.

I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:

Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If

which works fine also.

The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:

Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub

This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.

Here is the code for a typical entry of the InsertItem Template:

[code]....

All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"

How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?

Forms Data Controls :: FormView Data Source Calling Select Function On Page Load

Mar 24, 2010

I have a GridView and a FormView on the same page. They both have separate DataSources. This is a simple Master Details configuration, when a someone clicks on the Select link in the GridView, the FormView brings up the Details data. But for some reason the FormView's DataSource is trying to retrieve data when I load the page. This is causing an error because no ID is passed from the GridView.

Forms Data Controls :: Get A ListView To Automatically Update Itself?

Sep 6, 2010

I have a web page into which a user control is loaded. This user control contains a ListView. In the Page_Load event handler of the user control I have this code:

listView1.DataSource = TaskList; // Note: "TaskList" is a data table
listView1.DataBind();

It should be noted that the TaskList data table is actually instantiated in the web page. The user control then obtains a reference to it.

Everything described to this point works fine. Where I'm running into trouble is when I add a new row to TaskList. I had *thought* that the ListView control was dynamically connected to the data table, such that when I altered the contents of the data table in any way, that the changes would be automatically reflected in the ListView.

Javascript Onclick To Select Item With ListView Control?

Sep 19, 2010

I'm trying to implement a onclick event to select an item in a asp:ListViewControl.

<ItemTemplate>
<tr runat="server" id="MemberRow" onclick='<%#ClientScript.GetPostBackClientHyperlink(LvMembers, string.Format("Select${0}", Container.DataItemIndex)) %>'>
<td>

[code]...

However the onclick does not fire the ListView.Command or ListView.SelectedIndexChanging event? If I add a button with CommandName="Select" it works as expected? The POST data is the same!

{_EVENTTARGET=ctl00%24ContentPlaceHolder1%24LvMembers&_EVENTARGUMENT=Select%245&__VIEWSTATE=...}

Forms Data Controls :: ListView Does Not Insert Item?

Mar 13, 2010

What I'm trying to do is: I have a listview control on my page and in my code behind, I created an SQLDataSource object which I defined its Select, Delete, Update and Insert Command strings. I then binded that datasource to my listview. When I load the page, it's obvious the select command works. however, when I perform the insert, the ItemInserted event triggers, but the itemInserted doesn't trigger and there is nothing inserted in my database.I'm not sure what to do here. I also hard coded the insert values in my insert command. So it's not depending on the form values.
