I want to select a particular item in a dropdownlist by value, in asp.net using IronPython.
I found I can do it like this
listItem = ddl.Items.FindByValue(x)
if listItem != None: listItem.Selected = True
But I want to do it in one line
Suppose I have a list of a couple of thousand organizations and a user needs to be able to select one of them. The list is too large to populate in a dropdown at page load, and the user often knows what they want but it's not the first part of the organization name. That is, they know "Collections" but not that the precise name of the organization is "Department of Collections". So the user will need/want to type in some information.
It's easy enough to use an autocompleting textbox of some kind, but I don't want to allow the user to type in random text - they have to choose one of the organizations explicitly.
I am trying to set the item that is selected from a drop down list based on what it in the database for that particular record. I am filling the dropdown list with a SQL DataSource I have tried a couple of example that I have found for selecting the item in the list but I am always getting the first item in the list as the selected item. This is what I am currently working with:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If IsPostBack Then
Else
Dim ID = New Guid(Request.QueryString("ID"))

View 1 RepliesI have a drop down box with values that shows on loadUnited States Canada Now I have a function that is checking the users value from the database which is fired on a button click. What I plan on doing is comparing the string like if United States(db value) == United States (dropdown value) then go ahead and select United States in the drop down. When I do this I am getting the right value selected but it is making all the values the same for all records.
View 5 Repliesi am using a treeview control in my master page to act like a menu.it has different nodes levels e.g. root, parent and left.when i click an item from the tree view - i am taken to the page - but the tree view goes to its orginal state of being collapsed rather than keeping its state of nodes that have been expanded.does anyone know how i can maintain the state of the tree view in the master page
View 2 RepliesHow can I update the database with more than one item selected from the List Box. What I am currently doing updates only one item
objprp1.plugin_id = Convert.ToInt32(ListBox1.SelectedItem.Value);//passing the value(id) of the plugin thru the listbox property
I have written the piece of code below to get a productID from a gridView when the user clicks on the select link.
Convert.ToInt32(GridView1.SelectedDataKey.Values["productID"])))
However, if a user clicks on this more than one click the newer value replaces the previous. Is there a way to keep adding to the cart list when the user clicks on a new item?
Edit:
Here's my code for the Shopping Page:

I dont know if the location of creating the list is important? Wasn't sure if it was placed in the click event if it would keep creating a new instance?

I have several asp dropdownlists that are populated from a database. I would like it so that when an item is selected it opens a seperate page depending on the selection.
View 5 RepliesI have a complex UserControl with the main purpose to encapsulate DropDownList with a number of properties for advanced manipulation.
List is being populated on PreRender event depending on properties previously were set:
protected void Page_PreRender(object sender, EventArgs e)
{
sourceClient.SelectCommand = this.Property1 ? "exec a" : "exec b";
}
The most used property is ClientID:
[Category("Settings")]
public int ClientID
{
get
{
return Int32.Parse(DropDownList1.SelectedItem.Value);
}
set
{
DropDownList1.Items.FindByValue(value).Selected = true;
}
}
Getter commonly is being called by ControlPameters in SqlDataSources on pages with this control.
Setter - from markup: <uc:UserControl1 runat="server" ClientID='<%# Bind("ID") %>' />.
Why does setter from Bind is called earlier then PreRender? And DropDownList is empty and item selecting doesn't work! How to workaround this behavior?
May be I'm trying to run before I can walk, but here goes, I find coding for ASP so frustrating it's just not logical JIM!Anyways after my rant, as I'm a huge fan of the listview control in WinForms I'm trying to get the hang of it in ASP, wth not much luck so far.
View 3 RepliesFor some reason, I get an error half way through cycling through my items in a listview right before a record that has a null value for one of its items. It doesnt' haappen any other time. It happens after completing one cycle of the onItemDatabound eventfor a record in a row that is immediately before a particular null value in record immediatley following.My code is written to look for the proper edititemindex, and if it sees it, then it checks for null values for all the items. I can't even get that far, it errors just before the onItemDatabound even runs for the correc edit index
View 5 RepliesIn my project requirement user wants to enter a manual entry if they can not find an item in the drop down list.
Right now what I am doing is:
I set the dropdown list autopost back true and on selectedchanged event I am hiding the drop down list and showing a text box to enter a manual entry...
This is working perfect and no problems..
but the drop down list needs to change to a text box on only selecting a "unknown" option in the list...all other list items are doing unnecessary post back to the server with no use...
The following example displays a modal dialog box when the user clicks the button.What changes do I have to make to get it to display the dialog when a selection is made from the dropdownlist?
Note that if I set the TargetControlID property from "Button1" to "DropDownList1", teh dialog box is displayed when the dropdown is DROPPED rather than when a selection is actually made.

I'm trying to figure out some alternate ways of dealing with a smaller subsets of records from a larger set of records. This would be to increase performance and make it easier for the user to navigate, as opposed to trying to navigate a really large unwieldy record set. I know of a few ways a user can select a record from a record set. Selecting from a Grid View, drop down list, list box are some the first ones that come to mind. Another way I've seen, I think it was done with a repeater or User Control, is to list all of the letters in the alphabet as links and then only return the records that correspond to the letter that was selected.
It could also be done to allow the user to search by last name, first letter of the last name or some other similar method. I'm curious if there are any other ways of doing this. Does anyone know any other techniques that would create a better user experience when selecting a record or subset of records from a large record set?

I apologize in advance for my poor english:1. I have a dropdownList within my datagrid and its already populated fine (22 rows in my datagrid)2. The select item for the 21 row is the same as the select item of the 22 row3. When trying to do selectedIndexChange for the 22 row, it didn't seem to work.The error:
Dim ddl As DropDownList = CType(sender, DropDownList)
Dim dgi As DataGridItem = CType(ddl.Parent.Parent, DataGridItem)
Dim rowID As Integer = dgi.ItemIndex
The rowID keep staying at 20 even though the selectedIndexChanged is happening in row 22( ie. rowID should be 21)
This is the Grid am using ....

Every thing is working fine ....
Wat i did is in the first header of gridview dropdownlist i have binded the PO Item , so that user can select item n make invoice...
Here the problem is user will click addnewrow button to create new row second row , again user is able to select the same item what he selected in first row of gridview. here how to avoid duplication in the second row .

Item1,Item2,Item3,item4
user may select Item1 in first row , after clicking addnewrow button user will get second row

View 6 RepliesI have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?
If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.
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.

I use a ItemDataBound for a repeater.But i use 2 kinds of linq querys to bind it.Some of them has a MerkID, and some doesnt have this item.So its easy i need to do this:
if(e.Item.DataItem.Contains("MerkID"))
{
//Code for linq query 1
} [code]...
So of course the if selection doesnt work, but how can i do that? I already tryed this:
DataRowView drv = (DataRowView)e.Item.DataItem; if (drv.Row.Table.Columns.Contains("MerkID"))
But that doenst work because he cant convert it to a datarowview because its a linq class.So what to do? Right now i use a try and catch, but there are better solutions i guess...
