I use html Select in apsx page and bind it to data in database as dropdown:
<SELECT id="dd" name="dd" runat="server" DataValueField="ID" DataTextField="Name">
Then in code behind, I can get the selected item value(which is mapped to ID) as:
myvalue = dd.value;
But I want to get the selected text(which is mapped to Name), not the value in code behind. How to do it?
I have placed HTML 'Select' control on aspx page and it's items(options) are loaded dynamically using javasvript. The items in dropdown appear properly on web page. But when I select any item from dropdown, it's selected index is not returned in aspx.cs file. In fact, it shows selected index as 0 and size of 'Select' html control as -1. I have inserted the javascript(which inserts items in dropdown) in body tag. I also tried by calling javascript function on Body onload.

I have a textbox on my aspx page defined as:
<input name= tbdisplay type="text">
I can pick the data (I built a touch screen keyboard and I used javascript to write to the thextbox) from code behind using:
string textdisplaydata = this.Request.Form.Get("tbdisplay");
But I can't figure out the way to write back to the same display from code behind. In other words, I need to send a message back to the textbox from code behind. Because I did not defined the tbdisplay to runat="server", I can't see the control tbdisplay. Also, I can't run the tbdisplay at server because the keyboard doesn't work.
if I have a bunch of HTML code in my variable
is there some function that could remove all the HTML and output only the "clean" text?

View 7 RepliesI have several text boxes on a page that need to be filled out. When users fill out those boxes they need the ability to enter in bold, italics, superscripts, and trademarks. It has been recommended to use a WYSIWYG. The problem with a WYSIWYG is that it is all tied to 1 large text box. I just need a panel on the side that can hold Bold, Italics buttons to transform whatever text the user has selected to be Bolded/Italicized and then I need to be able to add in predetermined Superscripts and Trademarks where the cursor is as defined by the user. Now this would work with a WYSIWYG but I need this to apply to several (sometimes up to 10 fields on a page) text boxes on a page.
View 8 RepliesValues in multiselect dropdown not getting selected when Select All option is selected for a SSRS dropdown. There are multiple dropdowns on the page. We have one dropdown whose output is being used to populate the second dropdown using a stored procedure. When we check the Select All checkbox on the dropdown then ideally upon page refresh all the values should get selected in the dropdown, but in this case the page refreshes back to the blank dropdown, forcing the user to select the values again. The next dropdown too does not get populated. This makes it impossible to run the report for all the cases by using Select All. We ran the report on differnet database environments. My current location is Mumbai,India, the report worked fine when we ran it on a Bangalore,india database. This issue occurs when we try running it on a Chicago database server. I am using SSRS 2005, SQL2005.
View 1 RepliesI have a .net 3.5 web form with an ajax combo box and a text box inside it. The bombo box is bound to a SqlDataSource.
My requirement is to show/hide the text box depending on the text of the selected item in the combo box. If a particular string, say 'xyz', appears in the text of the selected item, the I will make the text box invisible. I enabled the AutoPostback, made the text box disappear in the SelectedIndexChanged event, and everything worked fine.
However, when users enter their own texts (which are not in the list items), I am unable to show / hide the text box. I've tried the TextChanged event but nothing happens. It seems the event is not trigger after I enter a new text and locate the focus to other place.
is there a way to prevent the user ented text from being inserted into the bombo box?
Use Html element SELECT in aspx page like:Data is feed by setting its property DataSource:MySelection.DataSource = IEnumerable collection DataSuppose data is stored in table in DB like:
1 - Option A
2 - Option B
3 - Option C
4 - Option D
From MySelection.Value, I can get the ID value, like 1,2,3.From MySelection.Name, I will get "MySelection", not the selected item name like "Option A"How to get the selected item Name?
List controls deriving from ListControl, such as DropDownList, ListBox or RadioButtonList, are populated by a list of ListItems. A ListItem has a Value and a Text property.
ListControl offers the following methods to access the currently selected item:
ListControl.SelectedItem returns the currently selected ListItem,
ListControl.SelectedValue returns the Value property of the currently selected ListItem.
Now, the interesting thing is:
ListControl.Text returns exactly the same value as ListControl.SelectedValue. It does not return SelectedItem.Text, as one might expect.
This is by design:
[code]....
The Text property gets and sets the same value that the SelectedValue property does.
This seems counter-intuitive and confuses people. My question is: Why was it done this way? I can imagine that providing a Text property is necessary for implementing the ITextControl interface, but why on earth would you choose to have it return the Value of the ListItem rather than the Text?
Can the select command of a SqlDataSource be given by code in the code behind file. Also by calling the SqlDataSource.Select can the select statement be executed?

To demonstrate that I could even use a Class attribute on an option elem I tried adding class attributes to options of a select elem in a static page and that works fine. I noticed that not many online resouces documented this so I figured I would explicitly set the record.

how to generate HTML code from the code behind?
I would like to build a form that generate an html code inside a for loop.
I will let the user enter the photo name and No. of photos
Then I will generate an HTML code like this:
<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />
depending on the No. of the photos the code will be duplicated in the loop
Then I will display the result of the loop in label or in a textarea to let the user copy it any where
The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses

View 1 RepliesI simply am trying to add a color to the select item background within the select elm after a user makes a selection from the select elm. The result right now is that in firefox, the colors will change, but only during selection ... after the selection has been made the background for the individual selection is still white.
This code works fine in IE but so far my efforts have been thuarted in FireFox.
[code]....
P.s I made an equivalent javascript method and made some attempts at it, but the result is still the same. The background color of the item is changed ... but only is visible when making a selection, NOT after the selection is made.
