I want to delete selected item of dropdownlist on Delete button click
Hint :1-It should also delete value from Database.
2-I want to Delete with the id of that selected item.
I bind dropdownlist in my page
protected void Page_Load(object sender, EventArgs e) {
BindDropDownList(DDL1, "city1", "name", "ID");
DDL1.Items.Insert(0, new ListItem("select city", "0"));
}
And SP
LTER procedure [dbo].[city1]
as
begin
select id,Name
from city
end
And design code
<asp:DropDownList ID="DDL2" runat="server" CssClass="daddsd">
</asp:DropDownList>
And here is imagebutton code that when click on it update data into table
protected void ImageButton_Click1(object sender, ImageClickEventArgs e) {
string data = Server.UrlDecode(Request.QueryString["BehCode2"]);
SqlCommand _cmd = new SqlCommand("insertinfo", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();
[Code] ....
Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load
DDL1.Items.Insert(0, new ListItem("select city", "0"));
And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.
I have a ListView which I populate using DataTable.
In each row I have a delete button. When the user clicks on the delete, that particular row is deleted in the DataTable Table.
After I perform the delete, I want to avoid page reload just to populate the ListView with the new set of records without showing the deleted row.
I suppose LINQ is the best choice for this. But I am unable to implement it.

View 3 RepliesI have a HyperLink control in a ListView, and I need to pass a couple of querystring parameters.
[Code]....
The first parameter is based on the current DataItem value in the LV.
Suppose I want to set a second parameter with a value from Selected.Item.Text in a DropDownList on the same page, how would the HyperLink look?
I have dropdownlist which items are generated using SQLDataSource. And there is a "Delete Button" next to it. When user selects item from dropdownlist and presses that button I want the item to be removed from DB. Here is the question "How can I achieve this using sqldatasource Delete Command?" I do can remove Item From Code Behind. But i believe it's more efficient to use sqldatasource delete command.

I have House_info table with Storetype column and I have radiobuttonlist in my page below is code
<asp:RadioButtonList ID="RBLType" runat="server" RepeatDirection="Horizontal">
<asp:ListItem Value="Galary"><span style="color:#676767">Galary</span></asp:ListItem>
<asp:ListItem Value="Product"><span style="color:Red">Product</span></asp:ListItem>
</asp:RadioButtonList>
Now I want if in Storetype column in database was="Product" then radiobutton item with text="Product" selected=true and if in store type column was="Galary" radiobutton item with text="Galary" selected="true"
How I can do it?
on my aspx I have the below DDL
<asp:DropDownList ID="ColorDDL" runat="server" DataSourceID="ColorObj"
DataTextField="Size" DataValueField="BustId" Width="150px"
AppendDataBoundItems="True">
<asp:ListItem Value="-1">(Optional)</asp:ListItem>
</asp:DropDownList>
If the user does not select an item I get an exception when i call the ObjectDataSource Method and DAL as below to insert into database

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.
Database Table: This data has been imported using Link to SQL

i use a dropdownlist in a page, with its items taken from a mysql database
i also use autopostback property...my problem here is that, every time i selecct an item, the first item in the list gets seelected
I am saving one selected value of Dropdownlist to Database and If I am retriving that value I want that only that value should display in dropdownlist.
For e.g I have Dropdownlist as

protected void ImageButton2_Click1(object sender, ImageClickEventArgs e) {
string data = Server.UrlDecode(Request.QueryString["BehCode"]);
SqlCommand _cmd = new SqlCommand("insertinfo", _cn);

Example If select type is 'DM', then only insert into the WM table.
string InserttoWM = ConfigurationManager.ConnectionStrings["CIMProRPT01testserverConnectionString"].ConnectionString;
using (SqlConnection Insertcn = new SqlConnection(InserttoWM))

Came accros your article "How to populate DropDownList in GridView in ASP.Net"
[URL] How-to-populate-DropDownList-in-GridView-in-ASPNet.aspx. Was able to duplicate your code w/o any problem. Works. Noticed that the values selected from the DropDownList are not automatically saved in database.
Question: is it possible just by selecting an item from DropDownList and then moving to another row within GridView save a selected value? I mean without using edit/update/cancel buttons but just by selecting an item from the DropDownList.
URL.... When I wrote this code in other page with different SP It didn't worked correctly I change SP in new SP I used INSERT code instead of UPDATE now when users didn't select Item from ddl3 it insert 'please select' in table these are my code
protected void ImageButton2_Click1(object sender, ImageClickEventArgs e) {
SqlCommand _cmd = new SqlCommand("insertSreg", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();

I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:
1- footer
2- Toolbar Control
3- Scrolling Data Grid with Header
ListView give us only one ItemPlaceHolder to Bind Data as per LayoutTemplate, so I cannot able to manupulate my Toolbar Controls with ItemTemplate :(, therefore I decide to use ItemDataBound to add ImageButtons Dynamically using Init Page Event and I am able to get the result as you saw above:
ImageButton with funnel icon is with CommandName="Filter"
ImageButton with magnifier icon is with CommandName="View"
ImageButton with stop icon is with CommandName="Delete"
Now I can able to handle Filter and View with OnItemCommand Event but when I click Delete button I am getting an error as shown below: The grid used CSS I am sending you the HTML and code behind to resolved this problem: HTML CODE:

On my page I have a list of items with ajax rating controls next to them. These controls I create dynamically from Page_load where I give the rating controls the rating of each corresponding item from the database. The problem is now that when the rating-event is fired I want to go to my event handler och add the new rating of the selected item into my database, but between my click and the event handler-method is fired the Page_load method is run, where all ratings is set from the database again, which means that the new rating I clicked on was restored and that the new rating I was supposed to update my database with will be the old rating already in the database. I create my ratings like this:
SqlDataReader r = cmd.ExecuteReader(); //calling a stored procedure
RadRating rating = new RadRating();
rating.Rate += new System.EventHandler(rating_Click);
rating.ID = r["id"].ToString();
rating.AutoPostBack = true;
rating.Value = Convert.ToDecimal(r["Overall_rating"].ToString());
In my event handler:
protected void rating_Click(object sender, EventArgs e){
RadRating rt = (RadRating) sender;
double myRate = Double.Parse(rt.Value.ToString());
updating database with myRate
}
From what I heard I need to recreate the dynamic controls i Page_load in order for them to persist throug postbacks, but when I do this the old rating writes over the new rating that I clicked on and need to use for database insertion. How can I solve this?
How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.
