Accessing values on the server for controls whose values were changed client-side
Let's say that I have two server controls, a label and a textbox: <asp:Label ID="Label1" runat="server" Text="Old value"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server" Text="Old value"></asp:TextBox>
Then I run some client-side code that changes their values: document.getElementById('Label1').innerHTML = 'New value';
document.getElementById('TextBox1').value = 'New value';
In the browser, they both visually have the value "New value". Howev...

How can I set client side values as server side values?Hi,
Can anyone tell me how I can get client side values such as
document.referrer, navigator.appName etc... into server side scripts?
There are some client side values I'd like to set as session vars and
insert into the db?
How do I go about this?
Thanks for any pointers
Davlon
PS (I'm using powersite 7.1.0.300)
Pass them as page parameters, e.g.,
http://myserver/myurl?document.referrer=whatever&navigator.appName=yadayada
Then, in your server-side script, just loop through the document.value array
and get these values.

Selected value in select list with javascript based off value in database
I've got a classic asp page with a select list. I need the select list's selected value to be whatever the user selected when they created their account.

Also, when the select list selected values change, there is a javascript function I call to disable text boxes.

Control.Value and Control.SelectedItem.Value
Can someone explain to me the difference between say, Dropdownlist.SelectedItem.Value and Dropdownlist.SelectedValue??
Just curious, Thanks!Tim
These are going to return the same thing. dropdownlist.selectedvalue is a shortcut to get the currently selected value in the dropdown. If that is all you want then you can just use that. If you want to access the currently selected item you can use dropdownlist.selecteditem and that return the item and you can then access any of the item's properties, including in this case the value property.

This same thing happens if you use the back button as well.

how can i Fill the controls on web page by selecting value from dropdownlist control.
Hi,
Currentlly i am working on a web application where i require to fill the web form with the selected item in a text box.
for example i have dropdown control named supplier_name, and i want to fill all the other controls values from database on the form when i select name from that supplier_name box,i.e , if i select name1, then related to that name, its code,address ,city should appear on related text boxes. I have done the same in windows application with c# , but the problem with web application(asp.net) is that, when i select Supplier _ it reloads the page and i loose the values in that combo box...i have heard of postback method but i donno how to use it to implement the same.
please any one send me answer..
Hello friend,
Yes, for sure you're experience this error because of the postback. You are populating the dropdown with data on the page_load event, correct? If so you just have to do it on the first time, because the ViewState will mantain the date between postbacks. To do this is quiet simple, just had this code over the code where you populate your main drop down:if(!IsPostBack)
{
//your code goes here
}Hope it helps!!! ...

Html.RadioButton sets all values to selected value after postback?
When using the Html.RadioButton() html helper with a value field that is an Enum to ModelBind() to, once you have chosen a value all the radio buttons of that name group are set to the chosen value instead of the value you gave it thereby making it impossible to select a different value.

retrieving checkboxlist values from database
HiI'm using a CheckBoxList server control and trying to select certain values which are retrieved from a database. How ever, i'm only getting one checkbox 'checked' even when there are multiple values. Public Sub getFacilities(ByVal queryString As String, ByVal connectionString As SqlConnection)
Using connectionString
connectionString.Open()
Dim command As New SqlCommand(queryString, connectionString)
Dim reader As SqlDataReader = command.ExecuteReader()
While reader.Read()
CType(FormView1.FindControl("facilityCheckBoxList"), CheckBoxList).SelectedValue = reader(0)
End While
End Using
End Sub The single value which is selected is correct, and i have also run the SQL command seperatly which shows that there should be multiple values! thanks
Hi!,
This is happening because you r resetting selectedvalue everytime while running the loop, so in the end of the loop it gives u the selected value for the last value.
U have to check each item for the checkboxlist and find a match for the value from the sqldatareader, if matches then set that Checkboxlist item's selected property = true;
While reader.Read(){
for (int i = 0; i < chk1.Items.Count;i++)
{
if (reader(0) == chk1.Items[i].Value)
chk1.Items[i].Selected = true;
}
}
Hope this will help. Regards
