DropDownLists Affecting Other DropDownLists?

Jun 25, 2010

I'm wondering how I can make one dropdownlist affect another one.. For example...You select your country from a drop down list of countries. On selecting it, another dropdown list becomes visible and displays the states of your country. I'm taking this data from a database, so it merely has to link to a different table for each country selected.

Also, I want the option of being able to add a 'state' to the database from the webform by typing whatever its called into the combobox so that future users will see that option.

Web Forms :: CustomValidators For 3 Dropdownlists?

Feb 20, 2010

I'm using a code I got from CodeProject [URL] about a validator that can monitor 3 form controls. I pasted it to my site, changed it to suite my parameters but seem to encounter a situation that can't satisfy my desire: Instead of making sure that all the 3 DropDownLists are filled without their default value, the validator cares only if at least one has been filled, and if so, he can call it a day. look at this code at tell me what am I doing wrong?

How To Generate Multiple DropDownLists

Aug 5, 2010

I have to generate multiple dropdownlists on clientclick. That is new dropdownlists on every client click.
I placed a button and wrote code on click event. protected void addReq1_Click(object sender, ImageClickEventArgs e)

DropDownList oDdl = new DropDownList();
oDdl.ID = "ddlReq" + (++i).ToString();
oDdl.DataSourceID = "DSUsers";
oDdl.DataTextField = "UName";
oDdl.DataValueField = "UName";
HtmlTableCell tc0 = new HtmlTableCell();
HtmlTableCell tc1 = new HtmlTableCell();
HtmlTableCell tc2 = new HtmlTableCell();
HtmlTableCell tc3 = new HtmlTableCell();
HtmlTableRow tr = new HtmlTableRow();

Here "DSUsers" is SqlDataSource. "i" is static variable. "serarch2" is html table with runat server tag The problem is only one control is getting rendred, after that on every additional click same DropDownList is getting replaced. No new DropDownList is added to the page.

Dropdownlists Creates Postback On Key Changes In IE?

May 17, 2010

I have created a label and a dropdownlist. The label has the dropdownlist as associated id.If I click on the label and then uses the mouse up or down the dropdownlist creates a postback for each click. This is quite anoying and doesn't happen if you click on the dropdownlist and uses key-up or key-down, or if you uses another browser than IE.Is it possibel to fix this, so you can use key-up and key-down without causing a postback, and first on the enter-key creates the postback (as it does if you click on the dropdownlist and not label)?

MVC :: Load Dropdownlists Used In Masterpage?

Jul 27, 2010

I am trying to use two DropDownLists (Cities, Categories) in a PartialView that will be used in MasterPage, meaning they will be visble all the time.

I tried to load them in HomeCOntroller, but that didn't work. I got an Exception.

I read something about making a baseController that the other controllers will inherit from, I have tried that, kind of, but I guess i'm doing something wrong.

This is the only code I got today:



PartialView (SearchForm.ascx)


Two question:

Where and how to load the DropDownLists is the problem. I have tried to load it in the HomeController, but when go to another page then it says that the DDLs is empty and I get a Excecption. Why do I have to use two forms for the ActionMethod to trigger ?

VS 2010 - DropdownLists With Datasource To SQL

Dec 16, 2011

On my webform, I have 3 dropdownlists with datasource to SQL. Through dropdownlists, I want the user to fill the controls, so I can get his location. One for his area, subarea, town or village. Actually the values appears great but I dont like when my page loads, the ddl fills with default values and second when I change, lets say the first ddl, it also full fills the rest with the first default values. All I want to do is, load my page with empty values, assign a value at first ddl, the second remains empty til I click on it and select a value and so on.. here is the code i use

HTML Code:
<div id="CreateAccountDiv" style="padding-top:10px">
<%--Label and Textbox for company--%>
<div><asp:Label ID="lblComp" runat="server" Text="επωνυμία επιχείρησης" CssClass="sizeLabel" ForeColor="black"></asp:Label></div>
<div><asp:TextBox style="width:250px;font-size:10pt" ID="txtComp" runat="server" CssClass="sizeText transparent" ValidationGroup="form">

Web Forms :: Dynamically Generated DropDownLists?

Jun 30, 2010

I have a dropdownlist on my page which has autopostback set to true. On postback I populate a runat server div with a bunch of other DropDownLists. I then have a button which does another postback to save the selections. Because the second set of dropdownlists are dynamically generated I cannot for the life of me figure out how to get their selected values?

1st DropDownList


Then when I try get the dropdownlists using a foreach on the div that I added the control to it does not work. They are populating fine, its just on the button click. I have tried EnableViewState = true on the dropdownlists and my code is correct because if I code them into the aspx then it works, its something to do with the state.

Making GridView Respond To 2 DropDownLists?

Mar 10, 2010

I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists.

For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List.

i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database.

AJAX :: Way To Use Two Cascading Dropdownlists With The Same Values

Mar 15, 2010

I'm trying to use two cascading dropdownlists with the same values -- one shows a code, and the other a description. They are sorted alphabetically, so they have the same values, but not the same index. Both are generating correctly. What I am trying to do is set the abbreviation when the description changes (and vice versa).If I use this javascript, it changes on the web page, but I get a null value returned to the form handler. If I comment out the CascadingDropDown control and load the TrickAbbrev from a database it all works.

C# - Filtering SqlDataSource With Multiple Dropdownlists?

Feb 4, 2011

I have an SqlDataSource at the moment, which I want to be able to be filtered using 3 DropDownList's. Basically, each DropDownList contains values for a certain column on the table, so when they choose one of the values, the SqlDataSource only shows values with that value in the relevant column.

So my table is somewhat like this:

ID (primary key)

And the 3 DropDownList's contain the following:

Manufacturers (value = ManufacturerID)
ItemTypes (value = ItemTypeID)
UnitTypes (value = UnitTypeID)

My filter expression for the datasource is currently like this, but it doesn't seem to work unless all 3 boxes have a value selected, which is not ideal. Any ideas guys? My filterexpression is below:

ItemTypeID = {0} OR ManufacturerID = {1} OR UnitTypeID = {2} OR (ItemTypeID = {0} AND ManufacturerID = {1}) OR (ItemTypeID = {1} AND UnitTypeID = {2}) OR (ManufacturerID = {1} AND UnitTypeID = {2}) OR (ItemTypeID = {0} AND ManufacturerID = {1} AND UnitTypeID = {2})

Create Dynamic Related DropDownLists?

Jan 9, 2011

I have three drop down lists that are related to each other:


Obviously the options in the CityDDL are created when the CountryDDL's OnSelectedIndexChanged event is fired, and ZipcodeDDL is created when the CityDDL OnSelectedIndexChanged event is fired.

That's all good....but what I'm wanting to do is dynamically insert multiple instances of these related controls.

I need to be able to click a button and add as many instances of these three related drop downs as a user needs.

best way to accomplish this preserving state and having all events work as they should??

I'm using .Net 4.0 and the current Telerik release.

Web Forms :: Tell If Any Textboxes Or Dropdownlists Have Been Changed?

I have a fairly sized relational DB and I hate to update every associated record in every table every time the update button is pressed. Is there possibly some way to tell on the server side or on the clientside via JavaScript?

This has to be a common problem with a good efficient solution.

AJAX :: Programming Model - Getting Values Of Dropdownlists

Feb 6, 2010

Imagine I'm developing a webform with two dropdownlists and a submit button. The second dropdownlist depends on the choice in the first, and both are loaded dynamically using webmethods being called with javascript in de ASPX page (ajax). When I submit the form to the server, to save the data, I can't get the value of those dropdownlists. I think it is because with client AJAX no viewstate data is being generated. I need to send the data to the server and save the webform data, and identify wich data is on each webcontrol.

Web Forms :: Parse To Label Date Dropdownlists?

Jul 20, 2010

I'm generating reports with a table, these reports are between some dates, the query is working, the thing is that the client does not want to have to type the date as for instance, reporte between 2010-10-01 and 2010-10-31. Since he only wants to get monthly reports, he wants to sleect just month and year. I created 2 dropdownlist one with month and another with year. I don't know if it is the best approach but what I want to do is that when the client seleces january 2010 automatically passes to 2 labels like this: 2010-01-01 and 2010-01-31 So then my query get these dates in the between fields.

The example attached here runs fine outside of a GridView. As soon as I try to insert this into a GridView, I get an error because I cannot identify the ControlID to use in the ControlParameter.

The code outside of the GridView looks like this:
