I'm working in ASP.NET.
I have a textbox where i need to insert manually some data, but that data is dependent on what is selected on a combobox.
So, to be easy to understand i give an example.
Combobox selected value "A" ---> Can only insert in textbox values "1,2,3,4,5"
Combobox selected value "B" ---> Can only insert in textbox values "6,7,8,9,10"
What is the best way to do that?
how can i insert valuefield and textfield in a combobox

View 2 RepliesI am working with three machines. The printer is shared and it is attached to one machine. Second machine contains published pages and on third machine I am developing the application. I have an application which uses combit's list & label for label printing. I am able to print label from the project. Means while debugging the project, printing works fine without any problem(from the development machine). But when I deploy(publish) this project in IIS by making virtual directory and then try to run, it does not work(on deployment machine). The browser freezes and does not show any error as well. After closing browser and running the same page takes a lot of time just to load the page.(not even shows the complete GUI, just white page...) Eventually I have to restart the IIS. Does anybody have idea regarding this?
View 3 RepliesI 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.
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.
View 3 Repliesin 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...
I am REALLY stuck with this and need a solution in the next 24 hours .i I have uploaded my asp.net web application to the web and have the database and connection strings functioning and reading the data from the database. But when I try to write to the DB
I get the following error :
Server Error in '/' Application.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

The wierd thing about this is the connection strings work from the local machine when I run from Visual Studio and I can write to the DB there, I just cannot write to the DB from the URL.
I am pretty new to asp.net but I am sure it has to be something to do with the web.config.
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.
When i open my page with a loginbox i whant the marker to start by default in the login textbox.

I am writing Watin test in MVC Asp.net app. I mvc app, all input are wrpped with form and every time an input or textarea is changed their form gets submitted by jquery like code below:
$("textarea", context).change(function() {
$(this).parents('form:first').submit();
});
This is perfect when changes are done by keyboard. However this doesn't trigger the form submit when input/textarea are changed by Watin TypeText() method. I tried to call Change() and Blur() events by Watin and also tried PressTab() with no luck.
So as the title suggested, I'm currently trying to compare the hashed answer in my database against the answer typed in the textfield by the user in the form.
I thought of hashing the answer in the textfield typed by the user first, and after that compare this newly hashed answer to the one in the database (which is already hashed). But when I typed in the SAME answer (before hashing) and hashed it to get the hashed value, by right the 2 hashes (in web form and database) should match? Somehow, it didn't. And I can't seem to get security answer right anymore (even though I typed the SAME security answer).
This is the code behind the button:

I tried in another way too, but still the same thing.

I am working on a class library using C#. I have designed 3 main classes to model our data. They are designed such that class A contains a list of class B instances, and class B contains a reference to a class C instance, ie:
[code]....
I feel like the class design works well for modeling the data and our business rules, but it does create a few limitations like the above situation. I liked the separation of the PolicyTerm and Billing for the ability to allow that code to be modified and tested independently. Also, I feel like it keeps each section smaller and simpler.
Having the following model Admin and AdminGroup is joined by AdminAdminGroup which has (AdminId, AdminGroupId) fields. When I add a new Admin row AdminGroups are associated with it automatically however this only works on INSERT.When I'm trying to update or associate more AdminGroup's with particualr Admin row (_repo.Update((DataLayer.Admin)row);) only Admin gets updated and no groups are ever modified.What is the correct way of updated "related" entities? so that AdminGroup also get's updated.
View 6 RepliesI want to have two combo boxes: One for categories and one for subcategories. As a category is selected in one combo box, all the related subcategories are displayed in the other combo box. EF 4.0 should be perfect for this. But the subcategory collections are always empty!
[Code]....
I can see that Lazy loading is set to true. I tried setting it to false and adding Include("Subcategories") but the subcategories collection is always empty.
I even tried using the SQL Server Profiler. Although I couldn't explain the timing, I could in some cases see the queries to return the subcategories. I even executed the query and it returned the expected results.
I'm really getting frustrated by EF. Although I'm fairly new to SQL Server, I could've had what I'm working on done hours ago. Instead, it's like a black box with no way for me to troubleshoot or determine what the heck is going wrong.
