Forms Data Controls :: Foreign Key Fields Are Moved To The Bottom Of Detailsview?
Sep 15, 2010
I'm not sure if you would consider it a foreign key field or not, but I have an agency table with an association to my Project table. It exists primarily to limit the input values of agency in the Project table to those listed in the Agency table. Anyway, everything works fine, except that when you insert/add a project, the Agency field is moved to the end of the list. I'd like to move it back where it belongs (further up the list).
I have a details view on my page that has a template field in it. In the template field is a button that when clicked, sets the visible property of another field to true. When this happens the whole detailsview resets and anything that was entered into other fiields is cleared. Is there any way to prevent the other fields from being cleared when the hidden field is set to be shown.
In this case I'm having, the ItemTemplate for various fields in my DetailsView (2 in my case) does not show up, but when you click the edit button, the EditItemTemplate shows up. I played with it, moving it around. No matter where I put it, one of the fields did not show up.
To get even stranger (and don't ask me how I came up with this), if I put a dummy boundfield BEFORE it, the ItemTemplate shows up. But this is totally absurd.
I have created DetailsView in designer page with SqlDataSource, Details view is with autoGenerateRows="false" i.e. I have declared my own fields. it is fine there, but what if I want to add these fields dynamically from codebehind with select & edit commands. I want to to use Details View in designer page and want to add fields from codebehind
I have a working gridView/DetailsView used as a member Lookup.
Some Fields in the Details View have data only some of the time, and when there isn't any, I want to suppress that row of the detail. No Go.
It seems that some of the function available in other controls don't exist so I cannot make the "field and its "header" Visible = "False"
FWIW, The control is nested inside a loginview control.
[Code]....
When I try and put logiin the control the error I get is:
Error 156 Literal content ('<asp:TemplateField ItemStyle-Wrap="false" HeaderText="PO Box:" Visible="') is not allowed within a 'System.Web.UI.WebControls.DataControlFieldCollection'. C:UsersBillDocumentsMy Web SitesNausetNewcomersMembershipCopy of Lookup.aspx 345
I'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.
I get a message like this if I change the "State" field to blank when doing an update
The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.
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?
I have set a couple of my DetailsView fields to readonly=true. In Update mode the fields are readonly but in Insert mode they are not readonly. What do I do to set it to readonly or blank (no field for entry)?
When you click the edit button in detailsview I want it to store some values in "PreviousAddress" and "PreviousVehicle" to show what the data used to be before it was edited... Just wondering what would be the best way of doing this?
I have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.
I have a detailsview in insert mode. I want to prompt the user to enter data in all fields, if left empty. Could someone please find a few minutes to show me how to do it?
I am trying to insert a foreign key into detailsview so that user didn't have to enter value every time. I am using the following code to do this but it is failing. I am not sure what needs to be done now.
Protected Sub LinqDataSource1_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceInsertEventArgs) Handles LinqDataSource1.Inserting LinqDataSource1.InsertParameters("Company").DefaultValue = Session("Company_new").ToString() End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim company As String = Request.QueryString("Company") Session("Company_new") = company End Sub End Class
I have two tables (Person and Location) In the Dynamic Data Site, when adding Location info, I am need to choose a person from the dropdown box which is populated via a FK. That dropdown box defaults to the field in "Person" that is titled "fname" which is first name, so it looks like "Jim" or "Steve".
I'm trying to have that dropdown box display the full name of the person it references which would be combining the fields fname and lname.
Would I do this inside a Field Template? Metadata? I'm kind of stuck on this.
If I look at the FieldTemplate for ForeignKey_Edit I see this:
[code]...
and it seems like I should be able to make something similar to "PopulateListControl" and use that instead, but I have no idea where this method even resides.
I have an EF model with a table with several foreign keys. These foreign keys are managed by associations. In code, I can get a strongly typed list of objects when I access that property on the object.
When I generate a strongly typed view, all I see are the int fields. Is there a way to get ASP.NET MVC to bind to the objects that are related as well as the main object?
I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?
I am trying to arrange the information from a SQL record into a 3 column by 3 row table to fit the form presentation that I want. I have placed on the page 3X3 table and then tried to place a detailsview in the first cell for the first picture called P1dv.
I have place a detailsview in the last cell that would control the paging of information called Controldv. I need to fiqure out how to link P1dv paging to Controldv page action. I am using visual web dev. 2005. I am not updating or editing these are read only views.
example of what i need the form output to look like:
I have a Detailsview working fine in ASP.NET 2.0 VB. where I can obtain any links or articles detailing the settings for the Template as a guide to me apply RegularExpressionValidators to a number of the fields in my application.
My application works fine with the Required Field Validator. The majority of examples that I have been able to find are using this particular Validator.
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.
I have a listview control and for paging I've used a datapager control. Problem is that it is appearing right hand side of the listview control. But I want to place it at the bottom of listview control. can any tell me why this is happening.here is the code
I have a formview tied to a gridview. The formview is used for insert, delete and update. A new row gets inserted to the top of the gridview instead of the bottom. How do I make the gridview add the new row to the bottom?
