VS 2010 - When Selecting Default Option For Combobox 1 / Second Combobox Is Disabled

Jun 13, 2012

I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.

AJAX :: Control Toolkit ComboBox SelectedValue / Does The Combobox Has As A Disadvantage That The Text Has To Be Unique

Apr 28, 2010

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?

AJAX :: ComboBox Input / Whenleave The Combobox It Adds To The Combox List?

Dec 3, 2010

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.

Jan 19, 2016

How do you refresh a combo box from clicking on something from another Combobox (using Visual Basic).

I don't want to use a button for this as i know it works that way by using .Databind() on the other combobox.

In access it is so easy by using the click event on a combo box but visual studio does not seem to use it.

Why Is "use Custom Server" Option Disabled In Visual Studio 2010

May 6, 2010

I have DotnetNuke loaded in Visual studio 2010. The 'use custom server' option under 'Start Options' is disabled. Why is it disabled?

What does 'Use Default Web server' default to? How do I change what the default is?
In earlier versions of VS i was able to switch between IIS and the internal web server (Cassini). Now it's more confusing in VS 2010!

Would the project type, Web Application Project vs Web Site project, affect the setting?

C# - Retaining ComboBox Within Grid

Nov 29, 2010

I have a comboBox within a grid. Basically to get it I have to use findcontrol. I am thinking of another option however. Within the init method I was planning on getting the value and storing it to a private static field:

C# - Cannot Select The ComboBox Item

Sep 14, 2010

I have two Comboboxes where the second one is dependent upon the first one.

When the SelectedIndexChanged event of the first Combobox fires then the second Combobox will be enabled.

After the event, the second Combobox is enabled but I cannot select the ComboBox item.

EDIT

I use Dev express Tools

First Combo I load in Page_Load Event

I use Server Side code:

protected void ASPxComboModule_SelectedIndexChanged(object sender, EventArgs e)
{
LoadSecondCombo();
LoadSecondCombo.Focus();
}

There is no problem in loading, but I'm unable to select 2nd combo item.
