I have searched everywhere on how to go about this but I havent been successful
I have a textbox and a dropdownlist
my dropdownlist contains three items which are red, blue and orange
Now, i would like a situation whenever the user type in blue in the textbox, it should assign the dropdownlist.selecteditem.value as blue.
How do I go about doing that.
i used the following technique to Select multiple items from DropDownList into TextBox with No duplicates, however i dont think it is the most proper way, any ideas. pressing again with same value selected choose another value from DDL and press button
Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
If TextBox2.Text.Contains(DropDownList1.SelectedItem.Text) Then
Dim m As New Label
m.Text = "duplicate !"
Me.form1.Controls.Add(m)
Exit Sub
End If
If TextBox2.Text = "" Then
TextBox2.Text = DropDownList1.SelectedItem.Text
Else
TextBox2.Text = TextBox2.Text + " , " + DropDownList1.SelectedItem.Text
End If
End Sub
When I try to use this code in a Form View, I get an error message:
Compiler Error Message: CS0103: The name avgift_namnTextBox is not in the current context
ROW: 35
Rad 33: if (dropDownlist.SelectedValue == "Other")
Rad 34: {
Rad 35: avgift_namnTextBox.Enabled = true;
Rad 36: avgift_namnTextBox.Text = string.Empty;
Rad 37: avgift_prisTextBox.Enabled = true;

View 3 Repliesim working on Visual Studio 2010, and im making a .net web page. The final idea is to use filters by using dropdownlist. By now i have 3 dropdownlist in cascade. The first filters the second and so on. Then by a grid view i display the selected items, right now i need to add an item that allows me to select all the items in the dropdownlist so in the next filters i like i have selected all. My code filters everything but i cant add this item. I only work in asp .net, not in the code behind wich i think is #C if im not wrong... i have to add a button in each dropdown.
I have read others post and the say that i have to add this in the dropdown>> "appenddatabounditems="True" and this sql sentence
WHERE ([PROJID] = CASE WHEN @PROJID= -1 THEN [PROJID] ELSE @PROJID END)
but it doesnt work.
heres the code.

I'm using a DropDownList with a data source which successfully populates the list. However, I want one of the items to be selected, namely the one where the value matches the path and query of the current request.
ddlTopics.DataSource = pdc;
ddlTopics.DataBind();
foreach (ListItem item in ddlTopics.Items)
{
item.Selected = item.Value.Equals(this.Page.Request.Url.PathAndQuery);
}
Using the debugger in Visual Studio 2008 reveals that item.Selected becomes true exactly once in the loop, but the rendered select has no option that is selected.
I'm using Visual Studio 2008 version 3.5. I have a dropDownList with over 800 names. The user wants to be able to type in it and select the name. I have seen this functionality in Telerik combobox but do not have license. How this functionality can be accoplished?

View 2 RepliesI have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.
i have a dropdown list with values
America
Asia
Europe
I need to the display the ddl as Select Type and when i click the dropdownlist to see the values in it, it should display the three values, but i should not use Select Type as a list item and it should not be displayed in the list. It should only be used as a default text in ddl.
For my ASP.NET page, in the code behind I load various items/options into a DropDownList but I do not set a default by assigning SelectedIndex. I notice for the postback SelectedIndex is set to 0, even if I never set focus to or changed the value in the DropDownList.
If not otherwise specified in the code behind or markup, will a default value of 0 be used for the SelectedIndex in a postback with a DropDownList? If yes, is this part of the HTML standard for selection lists, or is this just the way it is implemented for ASP.NET?
