Forms Data Controls :: Dropdown List Not Passing Info To Details View?
Jan 12, 2010
'm using a textbox to get the first 5 letters of the name.
An sqldatasource then finds the people who have names > than the five letters and picks up their ID numbers as well as their names.
After that I use a second sqldatasource to get one individual from that dropdownlist's persons name and id number and then using a detailsview I display that person.
Well both sqldatasouces work fine but it just does not pass the ID number when I debug it.
I have a dropdown list within a details view that allows me to set 1 or many categories to a perticular record(in this case a photo). The select command in this case only displays those catetegories that are not already attached to the selected photo.
all works well and as you select a category and add it to the database the category is removed from the dropdown list and is added to a gridview which shows all categories that photo is stored with.
My Problem is that when i delete the category from the gridview the dropdown list does not delete with said deleted item unless i do a "click in URL bar and press enter" to totally refresh the page.....
how to refresh the dropdown list in the details view after the gridview item has been deleted?
in one of the text fields I want to limit what the user can insert to a set of key words. So the obvious thing to do is to present the User with a drop down box to select a key word.
So I have converted the text field into a template and I thought I could replace the <InsertItemTemplate> in the details view with the drop down box.
Well it looks like what I want but when I INSERT the data that field is not inserted into the database.
So I guess I need to Bind the Drop Down somehow to the Insert - How do I do that ?
Here is my scenario.There is a users table and each user has multiple addresses(one to many) and I want to dispalay them like the image provided below
using listview only.I am really stuck with the deign of the page.There is a show and hide feature also.I can use only list view that is my requirement.
I have a vb.net page that has a editable detailsview. When a user wants to erase the data for a field, they highlight the data, and delete/backspace over it, and click update. However, the original data is still saved. If they are replacing the current data with new data, that works fine and updates/saves correctly. This problem only happens when the current data needs to be removed.
I have a detailsview which includes a drop down list bound to an array. However, when I click on the cancel button the dropdownlist values disappear. I have tried to solve the problem by rebinding the values back into list on the cancel command event, but this has made no difference. Does anyone know how to solve this?
In a gridview i am having two dropdownlist.in page load first dropdown will be populated and when an item is selected with in that based on dat selection i need to bind second drop down list.My problem is that selectedindexchaged event is not firing for first dropdown.The codings i used is below
I have on a page a gridview that can be filtered with one text box. I set up the gridview to show select and wanted to then connect a details view so that when you selected a row the entire details would show up. When I run it I get this error. Data keys must be specified on GridView 'GridView1' before the selected data keys can be retrieved. Use the DataKeyNames property to specify data keys.
I have grid view which databind from object datasource. my problem is i want to disply dynamic dropdown list on edit template based on the id which has in grid view. but still i can't figure out a way to do this.
I have a details view that appears when record is selected in a GridView. Can this details view be opened in it's own modal window that would allow me to use the full event model?
I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.
The example is given below( I am reading the book Sams Teach yourself ASP.NET 2.0 by Scott Mitchell. page 628)

I'm trying to get a record to show up in a details view as part of a Master Details. I was able to get this to work by setting the visibility to true for the Details View in the Page Load event. I now want the details view to show up when the Select button is clicked in the GridView's template field using the onClick event for the button. I don't seem to be assigning the correct properties to get this to work though. what property I should use with this? I know I have to get it from the GridView and assign it to the details but haven't gotten it to work. this is the GridView:
I have a gridview that has a dropdown on a template on the row. The user is wanting to change the value and update the record automatically. I know that when the value changes, I need to have the OnChange to trigger. I am not sure how to get the row so I can get the record ID so I can create a SQL statement to update this field.
Should I be using something other than the gridview?
I'm trying to setup a page that will utilize a dropdown list control inside of a grid view control using VS 2005 2.0 version. Everything that I can find online seems to only show the use of the dropdown list control using a data grid. I don't want to use a data grid because it doesn't have the functionality/ power as the grid view control. how I can incorporate a dropdown list control with the grid view control? Here is a copy of my code.
I have a gridview which display when person start n stop the project if same person do muliple projects it save n retrives eaisly i want to do that when i press select in gridview it give me the all about the person means if ali is working on 2 projects so it give me details like ali firsrt project is this time n date this , second project is this how can i do this ?
I have a partial view that has only a dropdown, i have called this partial view from a view. I can able to pass the model to this partial view and it renders successfully. However when some user selects a particular text from the dropdown, the corresponding value should be passed to view and it should be displayed in the label in view.
I have a details view that's part of a master/details scenario. When a record is selected it shows the details view. The Pay Status field is a label at this point, when the details view is in read only mode. But then when the edit button is clicked the Pay Status is a DDL that has it's items list populated declaratively.
I want the DDL to default to the text value of the label. This will be hourly or salary. This way if the user doesn't change it's value it will push the correct value to the db.
I tried something with the PreRender event but couldn't get it to work out. Below is what i have so far I wasn't sure how to assign the text property of the label or bind to the label to get the value and set that for the DataTextField.
I have two tables: Book and author and they have one to many relation.One book may have more than one authors. Book table has Title column and Author table has AuthorName Column.
I have search page contains two textboxes: Title Textbox and AuthorName textbox to search the record.
When the user type something and hit the search button it display the Title when click the title ; it redirect to detailsPage.aspx Passing value ID.
[Code]....
Then in the Details page there are: Title, authors and other more from these table column.
My problem is:
When the user search and hit the search button, it display the number of matches Title only. I want to display authors related to this title in this page and other are same(when click the title go to detailspage.aspx)
How can I display the related Authors to each title in search display page (Not in details page, I know in details page) ?
If user search "The Letters and life" in the Title textbox and hit enter data should looks like:
1. Author: Payne Paddy, sed ran, der virma and Caroline Barron.
Title: The Letters and Life of Elizabeth Despenser, Lady Zouche (d. 1408) [her letters and will provide a glimpse of her personal
I have a databound dropdownlist and have a problem with the default value it selects.When I attempt to edit a record the dropdownlist shows the first value in the list rather than the current value. I want the dropdown list to display the current value.
I'm sure this is very simple but I'm very new to ASP.NET.
How would i create a details view that also contains a list?
My aim is to have a details view that displays information about a person and then have a list on the same page that displays facts about that person.
Currently, my details view is working fine. I just need to add the list part. The details view inherits Models.MyViewModel which is a custom class as the details come from multiple tables.
