I'm trying change mode in DetailsView but my program haven't running.
My code:
protected
void DetailsView1_ItemInserting(object sender,
DetailsViewInsertEventArgs e)
{
if(....)
{.........
I am trying to handle the detailsview programmatically but I don't know what I am doing wrong. My details view control isn't going into edit mode. My code for my gridview's select button properly loads the data into the detailsview but once the detailsview renders clicking on "Edit" doesn't switch the detailsview contol into edit mode.
This code draws the information from my database and loads the information into the dataview:
[Code]....
This code is in my dvTeamDetails_ItemCommand sub and the beep works:

This code handles my mode changing event:

i have a detailsview in insert mode and that is bound to objectdatasource. now the class that is attached to objectdatasource is :
[Code]....
here ResturantId value has to be in session or from Dropdownlist and rest of the value from Detailview. So how to assign that value?
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 am trying to "reset" the DetailsView in View1 to ReadOnly mode if the user changes the index in RadioButtonList. Currently, it is working correctly for the first pass and second pass, but fails at the third pass. I want it to just cycle through the DetailsVIewdatabound event, but the cycle breaks on the third pass and I'm not sure why?

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 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.
Where do I put the logic and what am I missing?
I currently have a page that is used to insert or update records in a DetailsView using an EntityDataSource control. Insert is working perfectly. However, Updating is not. I have the default view set to insert. In PageLoad, I have:
[Code]....
However, the DetailsView always defaults to the first record in the table rather than the record with ID that is equal to the ID querystring parameter. I am not sure how to make it select the correct record. From spending a while researching, it looks like I might need to use a QueryExtender control on the Entity DataSource, but haven't been able to figure out how to configure the QueryExtender correctly.
There is also perhaps some sort of datasource="stuff", databind() that I could toss in there but again.. not really sure how to proceed.
I have a SQL DB with just 2 fields, ID and TEXT.What i was trying to do, was placing a Detailsview in EDIT MODE, then selecting from the DB like SELEC TOP 1 Text FROM DB.Then i placed a Ajax HTML Editor in the template field.How can i, keep the HTML Editor on the page, and use it for INSERT and/OR EDITING ?e.g.: on the first time the user opens the site management page, it will be blank, so it will show the HTML with no text on it. but the bottom button will be UPDATE and CANCEL. So when he enters the TEXT he clicks on UPDATE.

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.
I have one GridView called GV_IssTypeDesc and one DetailsView called DV_IssueLog.
The scenario is that i only want GV_IssTypeDesc gridview to appear when DetailsView DV_IssueLog is in edit mode. How do i accomplish this?
I refered to: [URL]
For now i have done the following:
UpdateIssue.aspx
<asp:DetailsView ID="DV_IssueLog" runat="server" Height="50px" Width="400px"
AutoGenerateRows="False" DataKeyNames="dbIssID" OnModeChanging="DV_IssueLog_ModeChanging"
DataSourceID="SqlDS_IssueLog" BackColor="White" BorderColor="#E7E7FF"
BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal">
<asp:GridView ID="GV_IssTypeDesc" runat="server" AutoGenerateColumns="False"
CellPadding="4" DataSourceID="SqlDS_IssTypeDesc" ForeColor="#333333"
GridLines="None" Visible="false">
UpdateIssue.aspx.vb
Protected Sub DV_IssueLog_ModeChanging(ByVal sender As Object, ByVal e As System.EventArgs)
If e.NewMode = DetailsViewMode.Edit Then
GV_IssTypeDesc.Visible = True
Else
GV_IssTypeDesc.Visible = False
End If
End Sub
The "e.NewMode" is underlined blue in color and it is stated "NewMode is not a member of System.EvntArgs".
How do i solve this problem?
By the way, I am using Web Developer 2008, VB.net.
I'm really struggling with this. How do I display my data with radio buttons in a detail view and bind it to my datasource like I've done with the textbox? The database values are int {yes = 1, no = 0, na = -1}. I want my user to be able to quickly update the radiobuttons instead.I'm working in C#.
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Electrical_Panels_Fastened_Securely") %>' ></asp:TextBox>

I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?
View 2 RepliesI have some ImageField in my DetailsView and when I changed it to Insert mode then ImageField is also became the textbox that allow you to type something, and my question is how I can make ImageField to be read only when I changed DetailsView to Insert mode?

In my code file
protected void Page_Load(object sender, EventArgs e)
{
DataSourceNew.Selected += new SqlDataSourceStatusEventHandler(DataSourceNew_Selected);
}
protected void DataSourceNew_Selected(object sender, SqlDataSourceStatusEventArgs e)
{
if (e.AffectedRows == 0)
{
dvNew.ChangeMode(DetailsViewMode.Insert);

why I cannot select the date into the box.

I am able to bind the first level nodes from the xml but not able to display the child nodes in the xml onto the detailsview on grid.

I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.
The scenario:
DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.
Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.
when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.
The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.
My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".
I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.

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.

I've got a DatalList control on a page that I intend on using for Editing Items. I've added a button control into the Item Template with CommandName="Edit", and when click the button on the item, the page Posts Back and continues to display the ItemTemplate for that item.
Here's what I've got...
[Code]....
How would I go about coding a button that would set a DetailsView in the "New" mode? (all fields blank and preferably place the cursor in the first field to be entered). I have the Insert mode turned on in the DetailsView but want to add a button outside of the DetailsView that would do the same thing.
