I am using autocompleteextender to receive list of projects. Is there any way that, given list of projects can hold a hidden values like a dropdownlist? I need project ID as hidden value...so that when I select a project from the list, I can retrieve the ID using C#/ASP.Net.
View 2 RepliesI am trying to use the key value pairs with the AutocompleteExtender to allow a user to select a name of a buyer from an autocomplete list and then insert the pkId of the buyer from the database into a hidden label for later use. I can get the Autocomplete part to work; however, when I fire my btn_click event to save my form information I lose the value of the pkId. Also if I try to hide the label I get javascript errors as if the control isn't even there. I have tried hiding the control by using the visible attribute as well as style="display:none;"

View 3 RepliesI have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
I'm having a time finding out I could not do something simple as :

This all located in a form, when I will find out the selected radio on change I will post the form and use the value of the hidden field to know the selected radio button. Nothing really difficult.

I must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).
Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.
Question 1: What is the best/simplest way to do this?
Question 2: How?
I am currently grabbing it on selectedindex change

View 1 RepliesI now can reference a field in the formview, but, assigning it a value is fighting me.
I want to assign the UserName field in the formview with the login name from the Master (HttpContext.Current.User.Identity.Name).
(A) I tried the likes of: FormView1.FindControl("UserName").DefaultValue = username but of course that doesn't work.
(B) Alternatively, I tried to edit the SQL so that I passed it the HttpContext.Current.User.Identity.Name but didn't have any luck.
InsertCommand="INSERT INTO [TechUserName] ([CertName], [CertLevel], [CertLast], [CertFreq], [CertDue]) VALUES (@temp1, @CertLevel, @CertLast, @CertFreq, @CertDue)"
temp1.text=(HttpContext.Current.User.Identity.Name)

View 2 RepliesSince setting item.selected to true will lose the mutual behavior and setting list.SelectedValue (readonly) doesn't get any button selected.
I am using list.SelectedIndex to assign the selected button. as follow :
//step 1. find the item by value
ListItem item = list.items.FindByValue(obj.ToString());
//step 2. find the item index
list.SelectedIndex = list.Items.IndexOf(item);
I make it into an extension method. But feel stupid about this procedure to simply just assign a selected value. does anyone have a better approach?
I have a very simple FormView that has several fields on it. There is a field that either returns a "1" or "0" based on conditions in the database. If the value is "1", I want to leave the label control as is (normal font, in black). However, if the value is "0" I want to change the font to bold and change the forecolor to red. Simple, right?
I am able to change the font-bold property using the code below, but if I use the code to attempt to change the font color, I get the following error message for this line:
An exception of type 'System.InvalidCastException' occurred in App_Web_hoge3m1x.dll but was not handled in user code
Additional information: Specified cast is not valid.

how am I be able to assign a value to my hidden field control? I have this web service that returns member's ID and name (e.g. 0001-John dela Vega). In order for me to search for a member, I'm using an autocomplete extender, now, if in case that I found the member I'd like to assign its member id to a hidden field. I ask this because I'd like to change the way my web service return data so instead of displaying the member's id and name at the same, I'll just show its member name.

you save data into a dynamic hidden field ,which is created dynamically during the handling of some postback event.what is the best way to retrieve it from this field upon a postback, (besides searching the request for the key of this hidden field and then retrieving the corresponding value as in the code below)?
