I have a DeatilsViews bound to an ObjectDataSource, I need set some default values for Insert and Update mode, which event(s) on which control(s) will be best to handle this?
I tried to set the default values using TextBoxes inside InsertTemplate, but the values are not saved to DB because 2 way bindings are lost.
I am using DetailsView to INSERT new records. I have a field "Paid Date"(date) that needs to be pre-populated with the current date. 90% of the time, the user will use the default date, however, there are times when the user will need to change the data as needed. I want to add this default in the code-behind. I DO NOT want to use template item.
View 3 RepliesHow 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.
A few questions regarding detailsview and gridview:
1) when page load, how can I default the detailsview to show the first record from the gridview? SelectedIndex does not have any effect to my detailsview.

2) how can I select a record in the gridview if my table has 2 key fields using below syntax?

when I click on "update" button of my detailsview I have the same values on my db table.It seems that the update method don't get my new values inserted in the "boundields" in editing mode.Below there is my code.
<asp:DetailsView ID="detailsview1" runat="server" AutoGenerateRows="false" HeaderStyle-Font-Bold="true"
I'm inserting data into a SQL database through a detailsview. When a user inserts an incorrect data type or leaves a required field blank it shoots off to a big error screen. Is there a control that I can use that will allow it to give an error (with a little star or something) that says which field is incorrect without the big error screen?
View 3 RepliesI want to populate my DetailsView with values from my first page.
This values get with session. I can display this values in my page. But i dont know how can i bring from my North Wind db. Here is my second page code behind in VB. How can i get this all data from my db based this values?

The DetailsView control has in its
Events an
ItemCommand event that uses the
DetailsViewCommandEventArgs event arg class which has a
CommandName property.
My questions are...
What are the possible values (e.g. "Select", "Insert", etc.) for this CommandName property when operating a standard, uncustomized DetailsView control?
Which order do the following fire in?
ItemCommand
ItemCreated
ItemDeleted
ItemDeleting
ItemInserted
ItemInserting
ItemUpdated
ItemUpdating
The "ing" events are currently being intercepted so that if the user doesn't have permission I set the e.Cancel = true and the "ed" events have redirects to send the user back to a list page that shows the items they just added/updated/deleted. However, I am not able to capture the Cancel button on the DetailsView control since there's no event for it. What I want is to redirect the user back to the list page if they click on Cancel as well.
I have a details view that is bound to a sqldatasource. The datasource has some extra parameters besides the updated data on the screen, they are;

I am want to take the old values of the details view from the detailsview1_itemupdating event and add them as a parameter to my sqldatasource.
[Code]....
So how can I then add this as a parameter to my sqldatasource?
Im not sure what i could have done wrong here but i created a dataset (ran a query and it returns the correct data) - created my BLL class - bound the ObjectDataSource to the control using the BLL - ran the site and all the data is showing as expected. Now i click edit columns (from DetailsView smart tag) and the selected fields are empty. I refresh the schema and this makes no difference. What could i be doing wrong?
View 4 RepliesBackground: I open a page that has a detailsview control using Accessdatasource. It is automatically opened with the row I want to update as I get there by passing the key as a URL parm. The update works for all fields except 2 template fields I added. I added a field for update date and updated by which I want the code to populate in the code behind so the user does not enter it. I have the same login on another page using an insert and it works fine. I cannot figure out what is wrong on the update and I tried everything. The code behind is in the OnItemUPdating event. code behind:
protected void set_update_date(Object sender, EventArgs e)
{
TextBox tbdate = (TextBox)DetailsView1.FindControl("TextBox_update");
[code]...
how can i populate the detailview in insert mode with values from gridview on selection?
Filter by date:
<asp:DropDownList ID="DropDownList4" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource3"
DataTextField="CDATE" DataTextFormatString="{0:D}" DataValueField="CDATE">
</asp:DropDownList>
[Code]...
I have EntityDataSource for DetailsView which is in Edit mode by default (showin Update, Cancel link buttons).
This datasource also has foreign key called PecID. If I change the value in textbox bound to PecID, it works fine.
Entering IDs is not very user friendly, so I add dropdownlist and new datasource.
When I select new value from dropDownList and press update the DropDownList's selection is restored to original (previous) value.
Other values in textboxes are saved as expected.
After few hours of trying to figure out what is going on, I got lucky. I figure out that it is important the order of TextBox and DropDownList in field template.
This is the working order (textbox before DropDownList)

This one doesn't work [Code]....

I have a gridview and a details view bound to an sql datasource that I am using to insert (detailsview) update and delete (gridview) records on a database. When the database table is empty and the gridview or detailsview binds to the sqldatasource the controls do not show up as there is no data to bind to. Is there any way of setting default values on the controls so that it will show when the table is empty and i can start making inserts to an empty table?

i have a check box list control that is used for showing related files to some post.
what i want to do is set the databound items "checked" to true by default
then,
if a user unchecks some item and clicks the save button. then the selectedindexchanged will fire and i will do some logic.
what i have done is.
--Set All Databound items to "checked" --
[code]....
in the end i want the item that was unchecked to be removed (all other items will remain checked). but even before that, when the user control is loaded all the files that were bounded are being deleted by the index change event.

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.

<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AllowPaging="True" PageSize="10" OnPageIndexChanging="countryGrid_PageIndexChanging"
