Forms Data Controls :: How To Use Dropdownlist Selection To Populate Textbox With Database Field
Feb 15, 2011
I would like the user to select an item from a drop down list. Next to the drop down is a textbox or label control. From the ddl selection I would like to populate the textbox or label from a database with a corresponding field from the database the dropdownlist was populated from. On selectindexchange event I can populate the textbox with the Unique id from the value, but I need to input a different field into the textbox. Can I use some sort of variable to assign the Textbox.Text = ?
I have a dynamically generated dropdownlist, that lists e.g. Company Names. I want to be able to select a particular Company and display associated information e.g. Name, Address, City, State... etc. in text boxes adjacent to the list.
I am trying to fire the following code from the dropdownlist "OnSelectedIndexChanged" property, but cannot 1) get the code to fire upon selection, and 2) populate the text boxes...
<asp:DropDownList runat="server" ID="DDLSalesPerson" DataValueField="keyid" DataTextField="FullName" /> <asp:TextBox runat="server" id="txtSalesPerson" /> My DDL is populated from SQL in the code-behind page.
I would like to alter the query that is run, depending on the selection made by the user in a drop down list on the same page. Would this best be done using a partial page update (AJAX)? Ideally it would be great to have the textbox result change quickly once the drop-down list value has changed, without a full page postback. I would like to change the SQL query to a completely different query if the user selects an option different to the default (page_load value) in the drop-down list. I would then like the newly retrieved result to be displayed in the textbox as before.
I have dynamically popute the data in Dropdownlist(Countries) and the On selected index event of Dropdownlist there is noeed to bind /populate the Checkbox list from database depending on the selections made from the Dropdownlist.
For example If I select Gujrata then all the cities of Gujrat should be visible and bounded to the check box list.
2) Once the checkbox list is bounded with data from the database, We need to select the checkbox from the checkboxlist and pass tyhe selected text of all the selected checkboxes fro the checkbox list as comma seperated values to database and then I need to Display in the Grid.
Below is my code for Dynamically populated/Bind DropDown list and get the States:
I have 2 dropdownlist, one is to dropdown department, and another dropdown staffnames. the secong dropdownlist will based on the selection of department as each department has different staffs i have 2 tables department and staff in my database , in my department table i have departmentid as PK and departmentname, in my staff table i have staffname and departmentid as FK. So my ques is how am i going to populate staffname in the dropdownlist according to the selection of department.
I am using asp.net 3-tier architecture, language c# for creating a web application. In presentation layer, I want to populate a textbox when I select an option from a drop down list. Under the code sample from .aspx page is given:
I have a one combobox and 3 textboxes and one sql datasource.
When I select the name in the textbox I want to show the values in the relevant textboxes. For instance, in the combobox when i select the Name of the employee the relevant information about this employee is shown in the 3 textboxes, i.e. age, cell #, extension.
populating the dropdownlist with column name. I have a gridview that has 7 columns . I want to have a textbox search and dropdownfield where user can select column name and type a word in search box and click search so that text for that column name is being search and displayed in grid. how I can fetch just column names from DB and search ?
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.
So far my edit page has a datagrid with the following code:
Am having one gridview. In that there is some details and one hyperlink (for Mail) and one Label (Mail Status).
The Mail status label have default value Not Sent for all fields. If i click the Mail link and send mail to the corresponding person, then the Default label value will be automatically changed its text to Sent.
