Can a dropdownlist control show 2 columns and then populate two different target textboxes based on its selection?
I need something like this:
A dropdownlist showing 2 columns, for example:
A USA
B England
C France
D Spain
Then, if B-England is selected, I need "B" to be moved to Textbox1 and "England" to be moved to Textbox2.
I have one dropdownlist control in my web page.
I want to fill my dropdownlist with multiple columns.
How can i acheive my goal?
Currently,below is my code.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source= E\SQLEXPRESS;" + "Initial Catalog=k;Integrated Security=SSPI");
SqlDataAdapter adapSel;
string mySQL = "select column_name from information_schema.columns where table_name='examtimetable' '" + dd_list + "'";....
I receive an error "Incorrect syntax near 'System.Web.UI.WebControls.DropDownList'."
How do I bind all my columns name in my database in a dropdownlist?
View 8 RepliesI have an emergency request that I need to sort it out very quickly as I did not notice it early :(.
I have a dropdownlist, the contnet in the gridview (sqldatasource connection) changes based on the value the user slects, say I have play1, play2 from the dropdownlist, I would like to show column1, column2 and column3 with user selects play1; show column4, column5, and clomn6 when use selects play2; the datatable actually includes all 6 columns.
I understand that I need to use something like RowCreated event, and I need to set up condition based on the dropdownlist value, but I dont really know how to.
How can i create DropDownList which shows multiple columns and only one column selected on selection.

View 1 RepliesI am trying to create a recipe system that will pull material amounts from an already built inventory database upon request for testing purposes of the different recipe runs. What is throwing me for a loop is that each time a user will request a recipe comparison they will have a different number of recipe trial runs for comparison purposes. In order to do this I'm guessing you will need to generate a gridview-like control with a dynamic number of columns which would be specified on a web form page prior to arriving at the recipe formulation page which will contain the control for the recipe formulation. As a result the user will have different columns and rows on this formulation page, with the rows being a static number of 30 (30 being maximum amount of ingredients to include in each recipe). The columns will contain the recipes to be compared, i.e. ProductRun1, ProductRun2, ProductRun3, where the number of ProductRunX will be determined by user input. So the user when they come to this aspx page will be presented with a blank editable grid of X columns by 30 rows deep. The left-most column will contain the ingredient names in a drop down box for users to select to input into their recipe and the rest of the columns will be editable fields where the user can type in the amount of each material to be used. The setup will look roughly like this:
| ProductRun1 | ProductRun2 | ProductRun3 |
ProductRun4 | ... |
-------------------------------------------------------------------------------------------------------
Material1 | Material1_Amt | Material1_Amt | Material1_Amt | Material1_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material2 | Material2_Amt | Material2_Amt | Material2_Amt | Material2_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material3 | Material3_Amt | Material3_Amt | Material3_Amt | Material3_Amt | ...|
-------------------------------------------------------------------------------------------------------
(...)
-------------------------------------------------------------------------------------------------------
Material30 | Material30_Amt | Material30_Amt | Material30_Amt | Material30_Amt | ...|
-------------------------------------------------------------------------------------------------------
So my question is how would I go about tackling something like this and what controls would I use. All of the forum posts around the internet show the GridView control being tied to data in a database already and not having the ability to have a fully blank and editable table upon the page loading so that it can accept user input. Another wrench into the situation is that the column numbers can vary. What control would be used in this situation or would it be better to use just a repeater of textboxes to build this type of control? Another thing is once the control is built how can you pull the data from such a control with the intentions of entering it inside a sql server database?
I want to put an input table on a web page using ASP.NET. The input table has 3 columns: date, quantity, and price. The number of rows is variable, depending on user input. The code behind will read the data and perform the necessary calculations. The data will not go into a database. It would be nice to have some client-side or server-side validation for the data, such as required fields and range checking.
Which control(s) in Visual Studio 2008 will perform what I want to do?
Iam working on an asp.net application.Recently client come with new requirement. Need a control which is similar to table or like gridview with rows and columns.It should allow user to enter data in the cells. And when the user press tab it should go to next cell and finally if we press enter key, it should validate the data entered in the current row and if data is correct it should create a new empty next row(like entering data manually in an sqlserver table). How can i implement this functionality? Can i use gridview / javascript to implement this functionality.
View 1 RepliesI'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:

View 14 RepliesI'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.
View 3 RepliesI want to create a ListBox control that supports display of items in two columns. It also needs to support selecting multiple items.
and the ListBox items should be CheckBox. What I need to do?
I also have a working application that popukates my datagrid with valid data rows from my DataBase. What I cant figure out is how to get each of the hyperlink lables to NAVIGATE to the correct and corresponding aspx page!
For example I have 5 rows in the datagrid and each row has its own hyperlink, each row contains contact and a short profile on 5 diffrent companies. For example when i click on let say row 3 that has (eg) Jimmy's Big Prawn's Restaurant listed in the the datagrid, I want to be navigated to a webform page dedicated to Jimmy's Big Prawn Restaurant.
[Code]....
I am guesing it has to do with the bolded text above, but "details.aspx" is just an empty webform, I would like the hyperlink to point to (eg) JimmBigPrawnRestaurant.aspx.
I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:
