Forms Data Controls :: Make A Default Dropdownlist Option Un-selectable?

Jan 18, 2011

How do i make the default entry in a dropdownlist not selectable? Right now I have a drop down and the users are able to select the default option that says (Select one)...here is what my code look like. I hard coded my options in there cause the list is really short and won't change ever. Right now, users can select the default entry and add it whatever list they are generating on the page...and I would like to make that default visible but not selectable.

Displaying Dropdownlist When It Has Some Value Else Make It Invisible

Jul 8, 2010

I have a dropdown list named "ddlCustomerDatabase' . Now this dropdownlist is associated with a sqldatasource. Now what I want is when there are no values in the dropdownlist ddlCustomerDatabase ie no row in sqldatasource asssociated with it, I want to make it invisible that is ddlCustomerDatabase.visible = False else it should be visible.

I have used IF ddlCustomerDatabase.text Is Nothing THEN,....used IF ddlCustomerDatabase IS Nothing THEN......used IF ddlCustomerDatabase.selectedItem, selectedValue, items.count THEN.. But to no avail.

So what should be the proper logic for achieving my simple goal, to display the dropedown list when it has something else to just make it invisible when it is empty.

Web Forms :: How To Make The DropDownList Case Insensitive

Feb 26, 2011

I have a DropDownList control that I am filling the selections in code and set the value to the value on the FormView Datasource row. However, if the case is different it does not set the selectedvalue to the current row value. It seems to be the case of the text because the table used to fill the dropdownlist has Jeep for a value and the data row has JEEP for a value. How can I make the DropDownList case insensitive?

Html - How To Make An SEO Friendly DropDownList In WebForms

Mar 9, 2011

I need to render a few DropDownLists on my page, allowing the user to select different Categories & Locations so as to return different result sets based on their selection.

However, I want each of the resulting selections to be crawlable. I know I could just render every possible Category, Location etc as standard HTML links on the page, which perform a GET request to the specified URL, but if possible I'd like to contain all these options within a DropDownList to keep things less cluttered.

If I were using MVC I would consider wrapping that small section of the page in a GET form, with each ListItem value being the destination URL (though I wonder if even this approach would be properly crawlable?).

I am using Web Forms though and am just having trouble trying to come up with a solution.

Make A TextBox Sync With SelectedValue Of A DropDownList?

Feb 5, 2010

I have a FormView with the following ItemTemplate. What do I have to do to make the Textbox reflect the correct TypeName for the selected campaign?

<asp:Label ID="campaignNameLabel" runat="server" AssociatedControlID="campaignList">Campaign Name: </asp:Label>
<asp:DropDownList ID="campaignList" runat="server" Width="200px" AutoPostBack="True" DataSourceID="campaignsSqlDataSource" DataValueField="CampaignID" DataTextField="Name" SelectedValue='<%# Bind("CampaignID") %>'>
</asp:DropDownList>
<asp:Label ID="campaignTypeLabel" runat="server">Campaign Type: </asp:Label>
<asp:TextBox ID="campaignTypeText" runat="server" Width="150px" Text='<%# Eval("TypeName") %>'></asp:TextBox>

ADDENDUM: I'm trying to do this with zero code. I can make it work if I use a separate data source for the drop-down and the detail fields in the ItemTemplate (i.e. the FormView's main data source), but I can't sync the FormView's data source with the drop-down's selection, because a ControlParameter on the FormView data source can't see control values in the ItemTemplate.

C# - How To Make A DropDownList Control Display Some Items In Bold

May 25, 2010

I'm working with a custom DropDownList control in ASP.Net and there's been a request to display certain items in the list with a bold typeface (NOTE - the control inherits from CompositeDataBoundControl so it can be data bound... not DropDownListBox). The control is bound to a table and there's a column in the table named IsUsed - if this is set to true, the corresponding item in the list should be rendered bold. (It should be noted here that this will only ever be viewed in FireFox.)

My experience is all in the middle backend tiers so the presentation layer is very new to me - can someone point me in the right direction? My initial thought was that somewhere in the custom control I would have access to all the rows that are returned from the data source which I could cycle through etc but I'm not sure if that's possible... There's also RenderContents which I can override... looks interesting!

AJAX :: Make DropDownList Change Values In UpdatePanel?

May 19, 2010

i have a DropDownList, which is inside an UpdatePanel. Now my problem is that, for example, lets say there are 3 item, Item1, Item2, Item3.

Now Item1 is the default, and i have code in codebehind that gets the value of the selected DropDownList, so for example, my code:

string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString;
string insertSql = "UPDATE Items SET ItemSelect = @ItemSelect";
using (SqlConnection myConnection = new SqlConnection(connectionString))
{
myConnection.Open();
SqlCommand HubInsert = new SqlCommand(insertSql, myConnection);
HubInsert.Parameters.AddWithValue("@ItemSelect", DropDown1.SelectedValue.ToString());
HubInsert.ExecuteNonQuery();
myConnection.Close();
}

Now the problem is that, once it is in an update panel, when you change the list to another item, so for example, i changed the list to "Item2", it will still be showing the first value of "Item1", i could have used Autopostback to get what i need, but then i wouldnt see the point in using update panel, since i dont want my page to flick.

Is there a way, or code to write that whenever the value of the DropDownList is changed, and i click my button, it will actually get the currently selected value, and not the virst default value,
