I have a FormView that is used to insert records into a table. It is set to a default mode of insert. When I click a LinkButton it makes the FormView visible and populates a DropDown List control via code. When I click the Insert button, it inserts the record into the table but then the DropDown List selections disappear. How can I keep the selections so that I only have to fill it once?

I have a drop down that lists all our 40+ locations.. I then have a list box with all our locations as well. The client is presented with the question which locations have you worked at before. If they pick say 3 locations, i need to remove or disable those 3 from the drop down. I have other code for creating a drop down, but not sure where to go with this.
Here is my code for the controls and code behind:

I have a requirement to allow users select multiple "Agencies" and populate the "Types" based on that selection. Cascading Drop down would have been a great fit if there is no mutliple selection involved. I am wondering if I could use a popup dropdown with chekcboxes. However, these checkboxes need to be populated dynamically by a web service. I am not very familiar with AJAX toolkit and what control would work best in this case.
View 1 RepliesI have a dropdown with names of project managers and a checkboxlist with names of team members. What I want to do is write the IDs of selections made from the dropdown and checkboxlist to the DB. I am using the following code, but only IDs from the checkboxlist are stored in the table. What can I do to store the ID from the dropdown simultaneously? Thanks for your help.

New at SQL and ASP.NET C#, bear with me. I have a form to insert into mulitple tables of a sql db. The form includes two listbox's, categoryIDlistbox and subcategoryIDlistbox, both with the ability to select multiple choices. Idea is that there is one record for the user created (Table1) and then that user can have multiple categories and subcategories assign to him/her in Table2
Table1:
userID
fname
lname
etc...
Table2
userID
categoryID
subcategoryID
If I understand correctly I need to use an array to take the multiple listbox items and save them to the tables. Not sure where the array goes in my code behind page to process the listbox and loop for muliplte selections. Here's my current code behind, where do I place the listbox array?

I have a datagrid which retrieves particular columns from an SQL database table. I also have a checkbox appended on to each row, so that selections can be made against rows of the users choice (i.e. select photos to add to favorites).
How can I code this (in VB.NET) so that these checkboxes are processed sequentially? I have heard an "array" might be best for this, but don't know how to code it. Essentially, I want the VB.NET to look through the datagrid list and to process only those rows with checkboxes checked, by applying some SQL based on these selections.

I have two tables - Reports, Usage
Report table:
RId
RName
RGroup
Usage table:
UId
UUser
What I want to do is make a page that will list all the reports in the Reports table and have a checkbox next to each name. A user can check each report they use and when they click "submit" it will insert each ReportID into the Usage table.I'm guessing that I should use a GridView to display all the Reports?How would I make it so that the "submit" button would insert each "checked" record into the Usage table?
I'm storing details about clothing in a database, and I need to save multiple entries for colour. For example, a user selects a top, and then needs to select the colours red, black, white and blue from say a group of tick boxes. How should I store this infomation, and what web controls would I use to help the user make there selection?

I have a gridview, in which i placed checkbox as Itemtemplate. My need is to restrict the user from selecting more than 'N' number of selections.
Eg: Gridview contains 50 records, that means 50 check boxes.
Max permitted selections: 10.
After the 10th checkbox selection, user should be prompted that..
"No more selections.. blah blah... "
Should i go for looping through records.. or is there any better way..

And inside that gridview you can see I have a dropdownlist called dpdTrueFalse. That dropdown has two values which I am loading from code behind like this...

I have a submit button outside that gridview that checks each row and the selected value in the dropdown. But for some reason, even if you select another item in the dropdown, it always selects the first item in the dropdown when I click the submit button. I reckon its because of the postback.
i have a dropdown with month names if the user has data for the month tht is selected then gridview displays the rows with day nos as per the month but if the gridview has no data for the same the dropdown or gridview via some event should call a insert procedure to insert data into the table for tht month with daynos ad rebind the gridview witht the rows just created

View 3 RepliesI currently have a gridview that has 1 column with radiobuttons. I then have a update button to update all the selected records. But what i want to do is add a step before the update. I want to add a multi-line textbox for each radiobutton selected to allow them to add notes/comments for each record before the update occurs.
Because the textbox will be large to allow them to enter the comments, i wanted to list them out seperately per record selected. Maybe a gridview is not what i need for the 2nd part, but thats the scenario and looking for suggestions on what / how to do it.
Example:
GRIDVIEW1
ID column1 column2 column3 radiocolumn
1 1111 2222 3333 Yes / No (selected Yes)
2 2222 3333 4444 Yes / No
GRIDVIEW2
ID NotesColumn
