Forms Data Controls :: Populate Detailsview Control From Dropdownlist Control?
Mar 7, 2010
I've got a dropdownlist control that the user can select an an employee name and that should then fill in the detailsview control with specific information about that employee.
My dropdownlist control works fine and I do have AutoPostBack set to true. For some reason my detailsview doesn't work. There's no error message. The detailsview control just doesn't show up.
Here's my code:
This is the sqldatasource control for the dropdownlist control:

This is the sqldatasource control for the detailsview control:
In the detailsview, I set a edit item template (a bounded dropdownlist control). But in database there are some data not set to a value (null). After clicking edit button in detailsview control I get the error about the value problem (Because after populating the dropdownlist, there is no item as null in it. )How to set dropdownlist selected index when the data is "null"?
I've put a DropDownList control within a LoginView control. I've got 2 SqlDataSource controls outside of the LoginView control, with the intent of databinding the items that comprise the ListItems of the DropDownList control, and another one for the data is stored in another table which has what was previously saved for the selection. However, when I've assign the SqlDataSource control to the DropDownList control's DataSourceID for the lookup table, I'm used to seeing the fields from the SqlDataSource control appearing in the DataTextField and DataValueField properties. However, they're not appearing there at all. Moreover, even when I try to type them in, its as if VS 2010 refuses to allow them.
I am new to this forum as well as Visual Studio and asp.
I am connecting to an access db using Visual Studio Express 2010.
I have a dropdownlistbox that pulls names from a database. When I select a name Gridview1 gets populated. Now I want to populate Gridview2 with more data when I click 'Select' link in Gridview1 but it's not working.
I am passing name (string) and number (number) fields to the gridview2 based on the gridview1.selectedvalue property and am seeing:
In page1 on clicking template field named Edit the record goes into detailsveiw (Edit mode) to next page.
In detailsview, I have already set True to AutoGenerateEditButton so that the user update record and Click UPDATE or CANCEL.
I want to show a message "Record Updated Successfully" on clicking update and the page redirects to the Page1 and refresh the page1 with the updated record.
I have a small question about the DetailsViewControl(DV).Probably most of us know there are three modes of a DV, edit, insert, and read-only.So we got edititemtemplate, insertitemtemplate and itemtemplate.Is there any actual difference between the 3 templates? I mean, if we don't generate the edit, insert and delete button by default. They are just three kinds of templates with different names, aren't they.
'' I try to add an TemplateField to my DetailsView control with calander control, in all modes. but can only add it to cell(0).how can i insert in the middle of the row?
Dim tmpfld As New TemplateField Dim c As Calendar = New Calendar() DetailsView1.Rows(0).Cells(4).Controls.Add(c)
I have a DetailsView control with two columns and 7 rows. I need the two columns to merge in row two and get rid of the header. I only the data from the DB to display no the header name in row two. How do I merge it in DetailsView control?
I have a databound label control (i.e. Label 3) inside an Item Template that's in a DetailsView control. I just need to get the value of those label and compare it to some string. I tried several ways (i.e. Find control, DetailsView.Row) but nothing seems to work. I don't know if I'm using the FindControl methos correctly or if I need to access the Row first and do the findcontrol method.
I have a DetailsView control where I use templatefields. One of them are textcontrol tempatefield and dropdownlist templatefield.
What I want to so is, when I select let's say "Dollar" value in DropDown list, textcontrol text to be assigned "USD". Basically, text property of textcontrol to be asggined based on dropdownlist selected value.

How would I go about populating a textbox within a FormView with the SelectedValue of a GridView? I'd like to know how to do this with the GridView on the same page as the FormView or a GridView passing a parameter from another page.
I have three cascading drop down boxes populated by way of a web service. I would like the selection of the third box to then populate the details View based solely on that selection. When I run the page, the DetailsView is populated with every item from the table (using paging) instead of only showing the details of the item selected in drop down. In the database the a field named ItemId is the identity for the table. Am I simply not passing this correctly to the detailsView from the ddl?
