Web Forms :: >>>Remove Dashes, Hashes, Spaces Populating Dropdown?
Aug 8, 2010
I have been searching the forum for how to populate a dropdown without "spaces" or "-" but I can not find exactly what I am looking for.Actually the data input by the user contains specaial character and using datasource the dropdown is being populated with the original data but every user has different style to insert data so I want to populate dropdown(within forview) without spaces or dashes, hashes. By making this change I may be able to populate dropdown in an asc or desc order.I know it can be handle from database but I want to do it with some coding technique in vb.net or asp.net.
I am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?
At webform I have TreeView whith adding nodes from code:
[Code]....

How to remove whitespaces if it is more than 2. What i want to say is -
1. If there is one whitespace, its OK. 2. If there is two whitespace, its OK. 3. BUT, if there is more than two whitespace than replace them with only two whitespaces.
String may be like this :- (it may contain any character)

When i request a page using browser / AJAX request i see lot of spaces and newlines which i think must be adding some overhead for retrieving the response as they too belong to characters means bytes and size. right ?
Is there some way it can be removed while sending from the server ? how ? (I am using IIS and asp.net for development)
I have a long string containing the ,<p> </p> and <br>. I want to clean my string from all these tags and spaces. How it can be done with String.Replace() method. I am doing separately right now, it is working but is there a way to do it at once, without replace() method.
I've currently got a form with two dropdown boxes on, and an XML file sitting on the site.
My two drop down boxes are Location and Date and what i'm trying to do it get the Location box to filter the XML and put the dates in the Date dropdown box.
I have a complicate problem. I'm not sure if I can explain it clearly. I have SQL table with columns: id, PartNo, ManuPartNo, GovtPartNum.
My boss want to do like this with 3 dropdown or 1 Dropdown with 2 listbox: If he select any PartNo, it will pull associated value For ManuPartNo & GovtPartNum
Also, if he select any ManuPartNo, it will populate back to other dropdown
Also, if he select any GovtPartNum, it will populate back to other dropdown
I'm so stuck & I don't know where to start on this.
when testing my query in the grid configuration wizard it works fine, but when i run the page it does not.
first - i select values from my cascading drop down list then enter values for two textbox (dates). then when i hit the button to populate my grid nothing is return back.
I have a dropdown control that has a list of names in it called PlayerNameDropDownList_Insert and a textBox called PlayerName.
When I select a name from the dropdown it populates the textbox correctly.However, when the page opens the first name is selected in the dropdown but nothing in the textbox. How can I get the textbox to populate with the value of the dropdown at pageload?
I have 2 dropdowns on my form, ddlMake & ddlModel. I want that ddlModel should have the corresponding value for which I have clicked the ddlMake dropdown, something like the cascading dropdown.
I need the simple task of populating a form from a dropdown if customer IDs.
The problem is I'm new to MVC and I no longer have events, so I'm not sure how my dropdownlist can have a postback event that does one thing, and my update button can have a postback event to do another thing.
Example, this only goes to the post action, so how does it know to load the customer or do an update:
I am running into some additional difficulties with dropdown lists, and I'm hoping you can correct my thinking.
I have a table populated with items; ITEM_ID, ITEM_NAME, ITEM_COST.
Here is my code:
[Code]....
With this code I get this error: DataBinding: 'ITEM' does not contain a property with the name '2'.
If I remove the assignment of DataSource to c1, the dropdown generates this error: 'DropDownList3' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
How should I code this so that the user is presented with a list of ITEM_NAMES, and that the ITEM_ID is stored in the value field so I can use it when the selection event is fired? I know I could databind the source directly to the dropdown list, but I am trying to understand the behind the scenes working of a dropdown list object.
I am populating a page with controls reading properties of a class using reflection. If the property type is 'String' I will add a text-box. If the property type is enum I am adding a dropdownlist. Now I have to populate the dropdown options with enums. How can this be done?
Both the enum definition class(Assignment) and the class(classOne) using which I am populating the page with controls are in the same Namespace(MySolution.Data). While looping through classOne properties when the property name is 'SkillLevel' I will have to go to assignment class get the members of enum SkillLevelEnum and populate the dropdown.
Same needs to be done for other dropdowns also.
My Code:
namespace MySolution.Data { public class classOne : MyAdapter { private string _Model;
I think that there is a good solution to remove white spaces from aspx page and from aspx.cs files. There are some solutions how to remove white spaces from html (aspx) but there is nothnig about aspx.cs.

I have a question about the encryption key/keys the standard ASP.NET Membership provider uses for creating the password hashes.Although we haven't deployed this new system we are working on yet, we might switch servers in the future. So I thought it might be a good idea to specify the encryption key/keys in the web.config file to avoid any problems with mismatched hashes if we do switch servers.We use the standard ASP.NET Membership provider ("AspNetSqlMembershipProvider"), passwordFormat is set to "Hashed" and we use Forms authentication.The current web.config file initially did not have any machineKey element. I used the web application and had registered and thus created an account and the hash of my password is stored in one of the aspnet_* tables.Then I created a machineKey element in the web.config file, and specified validationKey, decryptionKey, validation and decryption attributes. I had expected not to be able to log in with my password anymore, but I was surprised that I could still do so with the existence of the new machineKey specifying new encryption keys.So - why can I still log in?Does the AspNetSqlMembershipProvider not use the encryption keys specified in machineKey?
I have a textbox for City field and a drop down list box for office location which has to be filled up based on the City value.
How to populate the values of drop down list box from an xml file keeping the above consideration.
I am doing this in a asp.net user control and C# code behind
In future i need not change the code every time. Its only the xml file i change and the corresponding city related office locations get listed in the drop down list box.
I have many controls on my form, but in particular, I have 2 dropdownlists. 1 dropdown list has 2 values, and each value controls what the second dropdownlist displays. This is an edititemtemplate and both dropdowns have the selecteditem set via '<%# Bind("fieldname") #>' on page load.
THe problem is, if I change the value of the first dropdown, it errors out because the second dropdwon has a bound value that is no longer acceptable.
Can I cancel the bind of the second control, if the the first one is changed? I would like to cancel the bind, and update the values by using a different datasource depending on the value of the first dropdown or hardcode the new values.
If Dropdown1 has a value of "A" for example Dropdown 2 Shows Values "1", "2", "3"
If Dropdown 1 has a value of "B" , Dropdown2 Shows Values "4", "5", "6".
It binds fine initially, but if I change Dropdown1 from A to B, I want Dropdown2 to show the new values, maybe with a default of "Select an Item" and not error out b/c it's attempts to bind a value of 1, 2, or 3.
