View 1 RepliesI have downloaded the ajax control tool kit but i cant make the combobox display data from the db.
From what i read from online resources , it seems my syntax is correct...but data is not displayed!
Here some markup from my page
Â
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
<asp:ComboBox ID="Supplier" runat="server" style="margin-left: 57px; display: inline;"
Width="245px" DataSourceID="dsSuppliers" DataTextField="SupplierName"
DataValueField="ID" MaxLength="0" AutoCompleteMode="SuggestAppend"></asp:ComboBox>
<asp:SqlDataSource ID="dsSuppliers" runat="server"
ConnectionString="<%$ ConnectionStrings:unrafpl %>"
SelectCommand="SELECT [ID], [SupplierName] FROM [tblSuppliers]">
</asp:SqlDataSource>
there a way to change the width of the combobox control dropdown list? The problem is that because of the entries in it width of the combobox' dropdownlist exceeds the width of the screen resolution itself.So, is there a way to set a fixed width or any other better solution?
View 4 RepliesWhen the WebPage loads i would like for the Text to be cleared in Ajax ComboBox and/or DropDownList. However Setting the text to nothing or null doesn't seem to work. So I did some searching and found this...
[Code]....
Is there another way to clear the text other then adding a null item to the list? I don't really want the user to have a selection of "null", this seems like a hack job.
I specified DropDownStyle = "DropDownList", so that users are not allowed to enter text that does not correspond to an item in the list.but my problem is that I can not typed text in the combobox even if I type the text that corresponds to an element of the list of combobox!!
<asp:ComboBox ID="Cmb_unitte_filtre" runat="server"
AutoCompleteMode="SuggestAppend"
DropDownStyle="DropDownList" MaxLength="0" AutoPostBack="False" ></asp:ComboBox>
is there any way to use textbox which perform the functionality of combobox.Â

I am using AJAX ComboBox control (or I can use simple ASP.NET DropDown Control it does not matter) in my form. What I do is, I bind combo box control to my database and retrieve client names:
[Code]....
But here is the problem. I want First and Last names to go into separate TextBox controls (txtFirstName and txtLastName). Now it inserts Last Name and Firts Name in txtLastName control. At the same time I would really like to keep LastName + FirstName together in Combo Box.
I have the following items bound to my combobox:
Value: 1, Text: SNS
Value: 2, Text: ING
Value: 3, Text: ING
Choosing value 1 results in a SelectedValue of 1
Choosing value 2 results in a SelectedValue of 2
Choosing value 3 results in a SelectedValue of 2
does the combobox has as a disadvantage that the Text has to be unique?
I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.
in aspx i written as follows
<ajaxToolkit:ComboBox ID="cmbAddressAlias" runat="server" DropDownStyle="Simple" AutoCompleteMode="Suggest" CaseSensitive="false" AutoPostBack="true" RenderMode="Inline" Width="170px" CssClass="cmbProvince" OnSelectedIndexChanged="cmbAddressAlias_SelectedIndexChanged"> </ajaxToolkit:ComboBox>
it binding correctly(datasource dynamically binded) and it raises event too while changing index but it is not raising event when we manually clearing the combobox text..if currently combobox having text "ASP" then i manually select that entire text and using del key i am deleting but it is not raising event for me.. when i change index it automatically raising event...i need to raise event while combobox is empty...
