I've been playing with a certain detailsview for most of last week. This particular control is located within a panel that is hidden until a user clicks a linkbutton on a gridview. Then the panel's visible property is set to true and the detailsview is populated based on the commandargument passed through the link button. What I've discovered is that with each postback, the datakey or control parameter, still not sure which or if both, is lost. I've discovered a lot about ViewState and how controls work and am a bit surprised that something as common as using a detailsview within a gridview wouldn't be handled better than it is now. I have been able to get the proper information to build a correct select statement when the user decides to edit a record. I am now working on an update statement, but for some reason while I have the right key to update the right record, I am unable to access the user-generated data that was entered in the details view.
For instance, I select record with ID of 1 in the gridview. It pulls up the detailsview and I can view it. I then click edit. The correct record is still there. (It was previously going to default). When I enter new text in a textbox and click update, the app still knows I am working with record #1 but doesn't seem to be able to find the textbox control. I have currently hard-coded a value into the field just to see if I could actually get the record to update and it did. I am using an OnInit to cause the sub to run and think this might be the problem. However, I have been unable to find a better way around this.
Here is the sub that executes on the OnInit() of the detailsview:
Protected Sub notes_binding()
If notesDetail.CurrentMode = DetailsViewMode.Edit Then
sqlNotesUpdate.UpdateCommand = "UPDATE [Oilchange_Notes] SET [notes] = '" & CType(notesDetail.FindControl("notes"), Textbox).Text & "' WHERE [vehicle_id] = " & Session("unitNumVal")
sqlNotesUpdate.UpdateCommandType = SqlDataSourceCommandType.Text
sqlNotesUpdate.Update()
End If
sqlNotesUpdate.SelectCommand = "SELECT * FROM [Oilchange_Notes] WHERE ([vehicle_id] = " & Session("unitNumVal") & ")"
End Sub
And this is the error I get: Object reference not set to an instance of an object. If I'm correct about why it's not pulling the actual value or even acknowledging the control exists and is actually 'notes' (it is), then at would point would be the best to place this code?
I'm a beginner in Asp.Net and i have some problems to resolve. (It's hard to find good threads in french community)
I've a DetailsView linked to a GridView, in fact the DetailsView get the selected item of the GridView to return the associated datas.
I would like on the load of my DetailsView to get the values of the labels contained in my DetailsView to set my class's attributes.
But my .cs can't recognize the IDs of my DetailsView's Labels...
i have a DetailsView that is populated by a Linq to Entities query. Example query is below.

I have added a table to my FormView Edit template for structure and a button that pops up a form for information.
When the button is clicked I want a check box in neighboring cell to become checked. But I am having problems in the VB code behind, establishing the name of the check box to change its state. Its something like this....
FormView1.ItemTemplate.(CheckBox1.Checked = True)
Here's part of my markup
<asp:TemplateField HeaderText="Approval" Visible="false">
<InsertItemTemplate>
<asp:CheckBox ID="Approved" runat="server"/>This must be checked to allow the insert.
</InsertItemTemplate>
Here's my code

Is there a way to check if a user clicked the "Cancel" link button in a DetailsView control?

I´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
.aspx
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AllowPaging="True" PageSize="10" OnPageIndexChanging="countryGrid_PageIndexChanging"
CellPadding="4" ForeColor="#333333" Width="400px" Font-Size="9pt" [code].....
how can i check to see if a value in my detailsview is empty? What i have now is not working.
[Code]....
i have a UP and DOWN buttons ouside a gridview and a checkbox inside the templated field .I will check the checkbox to sleect a row , after that if i click on UP button the checkbox above the selected checkbox should be selected.
same with when i click on DOWN button the checkbox below the selected checkbox should be selected.
I have a check box in the grid.IF IsChecked has a value checkbox should be checked else not.Should i check the check box in the ItemDataBound event or will it get checked automatically.
<asp:DataGrid Runat="server" ID="gridProduct" AllowPaging="True">
<Columns>
<asp:TemplateColumn HeaderText="Employee Name">[code]....
I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.
View 1 RepliesI would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
protected void LinkButton1_Click1(object sender, EventArgs e)
{
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
try
{
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
}
catch
{
}
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";
}
2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType
DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";
First of all, I'm relatively new to asp.net (3.5) and all of its controls. What I'm trying to do is to split up a detailsview. I have a submission form containing quite a lot of fields that are supposed to be filled out by the user. In my design I have a tabstrip with headlines about the different sections of the form. For example:
Tab1: Personal Info
Tab2: Info about your car
Tab3: Contact info
I have tested to add a new "user" via a DetailsView and it works. But what I want to do is to split up the contents within the <Field> tags In the DetailsView In different div classes (using css and javascript to hide/show the right tab contents). But when I try to do this Visual Studio says that characters like <p> and others aren't allowed within the Field tags, which makes sense. Is there any control to use for these kinds of situations?
i want to bind the existing value in database to dropdown list in dititemtemplate

I need to test less than value of a integer value contained in a DetailsView
if ( DetailsView1.Rows[0].Cells[1] < 30 )
{
TextBox1.Visible = true;
}
getting error saying Operator '<' can't be applied to operands of type.TableCell' and int What am I missing? How does this differ from a GridView container?
What I'm trynna do is to input value in the TextBox1, and pass the string value to the label when button "ChangeText" is clicked.Pretty straightforward.

and how to use both of those checkbox (for example: when i click update in my detailsview, if the checkbox is checked will return 1 and if unchecked will return 0 and insert that value to database)
I have a detailsview which is used to input data into an SQL database. Some of the fields contain drop down menus which are populated from the database.
I also have a form that allows the user to select mutiple values from a listbox (populated from an sql database) by moving the required items from one list box containing all the available items into a second one containing the selected items. There is also a text box which is used to filter on the available items. When this is passed through to a stored procedure to be put into the database, it is passed as a comma delimited string containing all the selected values.
This works fine on a separate form, however I would like to include it in one of the fields of the detailsview. This creates a BC30451: Name 'ListBox1' is not declared error. I have looked for hours on the internet to try and resolve this but cannot find what I need for how to declare the list for use within the detailsview.
Here is the code for both the working multiselect form and the code for when I have tried to integrate it into the detailsview:

I have two detailsview, detailsview1 and detailsview2. Both are for pagination purpose.
Both are using same ObjectDataSource control (DataKeyName and DataSourceID is same in both ObjectDataSource control)
OnDataBound Event both called same Event RefreshDetailsView and In case of page index changing both used same method.
But when I do pagination using my detailsview2, this does not work only count got changed.
While detailsView1 works fine in case of pagination

What I'm trying to do is similar to the following within the gridview RowDataBound event, only with a detailsview:
DataBinder.Eval(e.Row.DataItem, "TotalPayment")
I created a DataBound event for the detailsview, and it doesnt recognize e.row. I've looked at some reference materials which tell me to use DataBinder.Eval(Container.DataItem, "TotalPayment") but then it doesnt recognize container.
