Forms Data Controls :: How To Pass The Selected Value Of Drop Down List
Nov 20, 2010
I added 3 values on DropDownList controls. ID= DropDownList1. If a user selects a value from the DropDownList, I'd like to insert the value on my DB (DB = Test) and in Column (Column = LastName). Below is the code I get when I double click on the DropDownList.
Protected
Sub DropDownList1_SelectedIndexChanged(ByVal sender
As
Object,
ByVal e
As System.EventArgs)
Handles DropDownList1.SelectedIndexChanged
End
Sub
I'm using vs2008 and add a dropdown list in my page. Default value of this control is "Digital". When I select another value from the list and press a button, next time the page displaying the same value, i.e Digital, not the selected value. I just want to show the selected value on the page.
I have a GridView that displays records from an Access database, and I want to filter the records using a selection from a drop-down list. The GridView populates on page load with all of the records. The drop-down list is populated at page load from a different table in the same database. The functionality of creating a new GridView filtered by the selection in the drop-down list is working. However, when a different page number is selected from the Pager of the GridView, the GridView "disappears," or isn't redrawn. The selected name remains selected in the drop-down list, but there are no GridView elements displayed. If I select another item in the drop-down list, I get a new GridView with the correct records, but then choosing a different page results in no GridView. I'm guessing there's something wrong with my OnPageIndexChanging for the GridView event code, but I'm not sure what. My code is below (C#, ASP.NET 2.0):
using System; using System.Collections.Generic; using System.Web; using System.Web.UI; using System.Web.UI.WebControls;
i have a small app. the database has two tables. Category(CategoryId, Category), Quote(Id, CategoryId, Quote) these two tables are related via FK (CategoryId). In my page i have a simple drop down list, button and lable. user selects a value from drop down list like 'politics', 'comedy', 'famous' etc and then they hit the generate quote which should fetch a quote from the quotes table by passing a value like 'politics'.
however, i need to pass an int value (ID) from my drop down since that is the value which will fetch corresponding quote using my SP but (1) how do i pass a drop down value's ID and (2) is the SP below correctly done?
SP code:
ALTER PROCEDURE [dbo].[GetQuote] (@CategoryId VARCHAR(2))
I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement { public IEnumerable<selectListItem> InactiveProduct { get; set; } public string[] InactiveProductSelected { get; set; } public IEnumerable<selectListItem> ActiveProduct { get; set; } }
I've created a web form and added a drop down list like so
<asp:dropdownlist id="foo" runat="server"/> then I created a submit button <asp:button id="submit" text="submit" runat="server" onclick="OnSubmit"/>
I defined OnSubmit in my .cs file but I have no way of getting the selected value of the drop down list. When I created the drop down list, there was no variable auto generated in the designer.cs file. Vars are auto generated in there for <asp:textbox/> why not drop down lists?
Alright heres my scenario. I click on an event and a new aspx page opens. I have two drop down lists and three text boxes. All populated with the data from the database. But when the page opens the drop down lists always show the item that is at the top of the list. Not the actual item that is in the database.
So say the name John should be there in one and a car names honda. But instead it shows alex and acura. These are just examples. But it alwasy starts with the item at the top
I have drop down list box that I would like to show two columns, is this possible? Or can it be done with a list box?The query correctly retrieves all of the table data to be displayed, one colum is an abbreviation, the other a bit longer description.
In my application i used drop down list dynamically so that if i enter the the value in the text box that many drop down list genrated with data from database. if i select the different iteam in the drop down list it will not changed it remains the first iteam of the dropdown list. if i use post back event is true in code part that drop down list is not visible.
nt i = 0; i < rows; i++) { TableRow row = new TableRow(); for (int j = 0; j < column; j++) { TableCell cell = new TableCell(); [code]...
I could not get the selected value of the drop down list to my controller. The selected value is always null in my controller. I have the folleong code in my view page
[Code]....
when I go to my controller class. I am trying to get the value of EA and days and I get null for EA and for days, its throwing an error. Although, I am seleting the values in the drop down list boxes. Below is the code for controller
[Code]....
in my above code Ea is always null and days is throwing an error saying this parameter does not exists.
I aggressively googled around, but could not find the information I am looking for. I know how to populate a dropdownlist using my view model andHtml.DropDownListFor helper method.
Suppose the drop down list contains U.S. stateId and stateName key value pairs. Suppose my ViewModel looks like
public class MyViewModel { public IList<State> States {get; set;} public int SelectedStateId {get; set; }
[Code]....
Do I have to change my implementation of my view model? In any case, how to get the selected item text of the drop down list?
how do i get the selected item in the drop down list and insert it into database (togethi populated the drop down with the values from the tables in database. It is dynamic, not static.i have a button in the gridview called 'add'. so when user clicks on it the row (whatever columns in the row) would be inserted into database. i am doing insertion/create for this.
when i am using dropdownlistin asp.net when i amselect the value from the list it cannot that the selected value but it can take only the first value of list.
I have a gridview with a drop down list. When I do the update I try to get the value from the drop down list, but I get an error saying that the drop down list control 'ddlType' can't be found.
I'm using Model-View-Presenter framework. When Loading a page, I'm having trouble setting the selected item that came from the Database.
In view, I know I need:
protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e) { presenter.DdlStatusSelectedIndexChanged(); // what should this pass? } Then in Presenter: public void DdlStatusSelectedIndexChanged() { view.DdlStatus = ??? // Should I pass the SelectedIndex? }
I also think that part of my problem is that DdlStatus I have as a List.
Interface:
List<StatusDTO> DdlStatus { set; get; }

In this code you can see the select statement that the customers are selected for display to the user. Order by is at least being used to disply in name order. but this example here is one of several similar dropdowns. I would like that if they picked one customer then the next view show should be the same customer
< order by customername " asp:SqlDataSource ID="Customers" runat="server" ConnectionString="<%$ ConnectionStrings:SecurityDB_20101025ConnectionString %>" SelectCommand="SELECT * FROM [Customers] WHERE ([CustomerId] = ISNULL(@CustomerId, '') OR @IsSuperAdmin = 1 ) > [code]...
How would I re-code the datagrid below so it displays as a drop down list? The data I want to display in the drop down list is ID="dgvFitters".Also, is it possible to display the data in a datagrid and in a drop down list simultaneously?
I have a ListView that contains a lot of editable items. Every item has some values, like; item name, item price, item size and so forth. I would like to add another editable column which should be a drop down list. This should list which sizes the item is available at, like S, M, L, XL. Some item are only available in S and M, while other items may just have a standard size (meaning none of the above sizes). So for example if you are to add an item called polo shirt and its only available in sizes L and XL then you should be able to do that. And then at the front-end where the users surf the items it should be like that when a users sees this Polo shirt he should be presented with a drop down list where he is only able to select L and XL
I can't figure out how to implement this in the Listview and the database. I have mentioned that I want a drop down list to appear in the back-end, this is not a necessity, anything will do as long as the front-end is showing a drop down list with the choosen sizes.
what the problem is that i want to populate drop down list manually
but the thing is i have 3 drop down lists
in first one user will select table name from where the data of 2nd Drop Down list will come
suppose user selected seo then the sql query would be select project_name from dropdownlist1.selecteditem
and this query will show project_name column of seo table in dropdownlist2
then user will select any project name from dropdownlist2 suppose he select salveo so i want that my text box will get populate with project_id of project_name
suppose the project_id of salveo is 123 then automatically in textbox it will enter 123
