C# - Adding Custom Options In Bound Dropdown?
Apr 5, 2010
I have a bound dropdown list populated with a table of names through a select, and databinding. it shoots selectedindexchanged that (through a postback) updates a certain gridview.What happens is, since it runs from changing the index, the one that always comes selected (alexander) can only me chosen if you choose another one, then choose alexander. poor alexander.What I want is to put a blanc option at the beginning (default) and (if possible) a option as second.I can't add this option manually, since the binding wipes whatever was in the dropdown list and puts the content of the datasource.

I have a drop down list with two options Score and status. On selecting score select score i display a MultihandleSliderExtender to select the score range ex: 10 to 20 and on selecting status i display dropdown list . On displaying one option i make the other as not visible.
Now comes the problem in Firefox (works properly in IE) when i select score and then try to change my option to status it does not allow me to do so i.e the mouse over event on the dropdownlist is not working.

I have a droplist, that I generate from an Excel file.
Code:
cmdExcel.Connection.Open()
dropdown1.DataSource = cmdExcel.ExecuteReader()
dropdown1.DataTextField = "BCName"
dropdown1.DataBind()
cmdExcel.Connection.Close()
I want to add two more options to the droplist:
dropdown1.Items.Add("Select")
dropdown1.Items.Add("All")
But if I do like this they are added after the items from the databind. I want the Select and All as the two first ones and then get the rest from the databind. How do I do that?

I'm using a book to create a shopping site and need to change the following code so that the current dropdown list, of colour options, is replaced by just read only text. I'm a novice and despite best efforts I can't fathom it out. If anyone can change the code for me I would be extremely grateful.
The code below is the code-behind page for a Product List page where I want each product displayed to also display its colour options as just text (I don't need the shopper to select a colour choice until they click through to the detail page)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
public partial class UserControls_ProductsList : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
PopulateControls();
}
private void PopulateControls()
{
// Retrieve DepartmentID from the query string
string departmentId = Request.QueryString["DepartmentID"];
// Retrieve CategoryID from the query string
string categoryId = Request.QueryString["CategoryID"];
// Retrieve Page from the query string
string page = Request.QueryString["Page"];
if (page == null) page = "1";
// Retrieve Search string from query string
string searchString = Request.QueryString["Search"];
// How many pages of products?
int howManyPages = 1;
// pager links format
string firstPageUrl = "";
string pagerFormat = "";
// If performing a product search
if (searchString != null)
{
// Retrieve AllWords from query string
string allWords = Request.QueryString["AllWords"];
// Perform search
list.DataSource = CatalogAccess.Search(searchString, allWords,
page, out howManyPages);
list.DataBind();

firstPageUrl = Link.ToSearch(searchString, allWords.ToUpper() == "TRUE", "1");
pagerFormat = Link.ToSearch(searchString, allWords.ToUpper() == "TRUE", "{0}");
}

else if (categoryId != null)

}

list.DataSource =
CatalogAccess.GetProductsOnFrontPromo(page, out howManyPages);

DataTable attrTable = CatalogAccess.GetProductAttributes(productId);
// get the attribute placeholder

// temp variables
string prevAttributeName = "";
string attributeName, attributeValue, attributeValueId;
// current DropDown for attribute values
Label attributeNameLabel;
DropDownList attributeValuesDropDown = new DropDownList();
// read the list of attributes
foreach (DataRow r in attrTable.Rows)
{
// get attribute data
attributeName = r["AttributeName"].ToString();
attributeValue = r["AttributeValue"].ToString();
attributeValueId = r["AttributeValueID"].ToString();
// if starting a new attribute (e.g. Color, Size)
if (attributeName != prevAttributeName)

if i click on pwd dropdownlist then it should show the list of numbers.
if i select any one of the value in the dropdown list then it should insert into the
database.

I've tried to wrap up my problem with a complete example below - the original problem is part of a jQuery plug-in that I'm writing to extend the behaviour of an ASP.NET ajax application I already have.
The aspx page below has one drop down list which is marked for auto post back. I've also bound a change event using jquery (which ultimately I will swap for a .live() event to maintain the binding after the update panel refresh.) The problem is, when the jQuery event is bound I see two ajax begin requests and page_loads fire but only one ddlTest_OnselectedIndexChanged event. One of the page loads is malformed too - the content-length states it's about 300 bytes long whilst the totalBytes is 0 and form data empty. This does not happen if I bind to the click event of a button.
why the erroneous page_load event is firing ?

I recently got a form to work with the "HttpContext.Current.User.Identity.Name.ToString" String. That basic idea was I needed a hidden form field so that each record submitted would include the UserName of the user logged in to the membership. However, whenever I try to create a custom query for the gridview, it doesn't submit. how I would go about doing this? Code as below:

I have a dropdown list populated from the database. There is also a button next to the dropdownlist that once clicked on. It takes the item in the dropdownlist and use that to populate the gridview.however though, I would like to add a blank to the dropdownlist and message that would say, you have selected a blank whenever the user selects the blank from the dropdownlist and clicks on the button.

I have custom gridview that inherit from the regular gridview.
On of the features is that is has a built in page size dropdown in an extra header row.
Another feature is that this extra header row has a place holder where aditional controls can be added but here is where I have some problems.
When I add a control that is created outside the gridview to the gridviews builtin placeholder and tries to do anything that performs a postback the gridview dissepears, but appears again on a new post back.
Here is the code for the gridview:
[Code]....
And this is the way it is used in a usercontrol on page, the gridview is called gvList and the control that I try to add to its placeholder is the phrExtraHeaderControls:
[Code]....
What can be wrong, is the viewstate messed up in the postback so that the gridview can't be rendered?
