C# - ListBox - Value Being Set To Text Field?

Mar 3, 2011

When adding list item the Value field is being set to the Text field. Initially I though the problem was related to the input parameter for the primary key ( group_type_id ) as it is configured as OUTPUT variable.

Interesting enough, when I Watch all of the values, everything is correct.
So for example, I'll watch these:

ddr["group_type_name"] comes out as "Dept"
ddr["grouptypeid"] comes out as 4

When the item is created however,

itms.TEXT = "Dept"
itms.Value = "Dept" <-- THIS IS THE PROBLEM

I'm at a loss why the listbox values are being set to the text values when I can clearly see the data reader values are correct. ?

Code sample here:

Web Forms :: How To Display Text In A Listbox / How To Make The Listbox Pad With Spaces

Oct 11, 2009

I want to display text in a Listbox to make it look as though there are multiple columns. To do this I have tried using the string.PadRight method.


When I step through the above I can clearly see that the text is padded and as expected. When it renders to the browser however the additional spaces are remove.

If I change the code to put an asterisk instead of a space the text is padded. i.e. it works as expected.

How can I make the listbox pad with spaces?

Web Forms :: Disable Items In Listbox Using Database Field?

Oct 5, 2009

I have the following statement

protected void Page_Load(object sender, EventArgs e)
{ if (!IsPostBack) { // bind the ListBox.
ListBox1.DataSource = new string[] { "AA", "BB", "CC", "DD", "EE" };
ListBox1.DataBind(); } } protected void ListBox1_DataBound(object sender, EventArgs e)
{ // find the CC item.
ListItem ccItem = ListBox1.Items.FindByText("CC");
if (ccItem != null)
ccItem.Attributes.Add("disabled", "");
// find DD item ListItem ddItem = ListBox1.Items.FindByText("DD");
if (ddItem != null)
ddItem.Attributes.Add("disabled", "");

My listbox has the following values:


This code above disables the user from selecting CC and DD. Working fine.

now how can i make this dynamic, for example, if there is a read_only flag in the database which has the value 0 or 1. How can i ammend the code above to say if the flag is 0 disable otherwise enable..

Web Forms :: Store Selected Index Of Listbox In Hidden Field And Then Return To That Value On Postback?

Jan 4, 2011

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

Web Forms :: How To Drag And Drop Highlighted Text To A ListBox Item

So every item dragged to a listitem will have ListItem(1), then if two items are dragged it would be ListItem(2), etc. Also, is it possible to drag items off of a ListBox control so they won't appear anywhere?

C# - How To See Text From One Text Field In Another Text Field

Sep 6, 2010

clarify: i am using a virtual keyboard that has to work on deferent text fields, and deferent pages, every time i click on a text field it sould pop up and every key i press i need to show on the text field....the problem, as every one knows, is to bind a deferent text field to the virtual keyboard, And as i said, also, to use it on deferent pages without rewriting the keyboard code for every page again and again, some thing that will not do... still can not give any code as there is no code to give, so there is no code...

i don't have code to show becouse i am trying to figure out how to do this and not showing a problem...

Background: I have an aspx file that holds a keyboard div and a hidden TextArea or an Input type=hidden (not decided yet). This page is a user control so it cen be used in all the pages that needs it...

What i am tring to do: Using JQuery bind('focus',...) method to bind any field in a certian aspx page (not the keyboard UC itself) to the hidden text field, i want that every thing i click on the keyboard will show in the text field that is on focus....

Can i relate in JS/JQuery to a field that is in a different page, will it recognise it? how can i do the bind, how can i transfer text from one field to another? if there a better way to do this, i will be happy to hear about it...

How To Make A Text Field

Mar 1, 2010

I know that this is easy for those that know but alas this is not me ;)

I have a multi part form that is going to write to a dB.

As a point of reference I can offer [URL](i.e., the quote process) as a model for my project.

I need to write a record on the first page and then use the auto number generated from this to populate the child records with the parent's key field.

What I was hoping to do is write the record and then send the data from the dB to the second form. Iwill then need to repeat this process for the children of the child

I am only moderately familiar with ASP.net

one thing to add is that i am not forcing the user to create an account in order to maje the initial inquiry, only if they wish to reaccess theinformation at a later date.

VS 2008 DataFormatString For Text Field?

May 11, 2010

I have an asp gridview that I am exporting to Excel. The data exports perfectly except for fields that are text fields with leading zeros. I have a field in the data grid for job number that has leading zeros. When that data is exported to Excel 000564 gets exported as only 564.Is there DataFormatString expression that I can use that will force that column to be exported to Excel as text.I have also thought about changing the SQL statement to so the job number is definitely a string by concatenating using J + jobnumber as JobNumber but my users dont want a J in front of the job number.Is there a DataFormatString expression for a text string?

Optimizing A Table With A Huge Text-field?

Mar 4, 2011

I have a project which generates snapshots of a database, converts it to XML and then stores the XML inside a separate database. Unfortunately, these snapshots are becoming huge files, and are now about 10 megabytes each. Fortunately, I only have to store them for about a month before they can be discarded again but still, a month of snapshots turn out to become real bad for it's performance...I think there is a way to improve performance a lot. No, not by storing the XML in a separate folder somewhere, because I don't have write access to any location on that server. The XML must stay within the database. But somehow, the field [Content] might be optimized somehow so things will speed up...I won't need any full-text search options on this field. I will never do any searching based on this field. So perhaps by disabling this field for search instructions or whatever?The table has no references to other tables, but the structure is fixed. I cannot rename things, or change the field types. So I wonder if optimizations is still possible.Well, is it?The structure, as generated by SQL Server:

CREATE TABLE [dbo].[Snapshots](
[Identity] [int] IDENTITY(1,1) NOT NULL,
[Header] [varchar](64) NOT NULL,[code]....

Performance isn't just slow when selecting data from this table but also when selecting or inserting data in one of the other tables in this database! When I delete all records from this table, the whole system is fast. When I start adding snapshots, performance starts to decrease. After about 30 snapshots, performance becomes bad and the risk of connection timeouts increase.Maybe the problem isn't in the database itself, although it's still slow when used through the management tool. (Fast when Snapshots is empty.) I mainly use ASP.NET 3.5 and the Entity Framework to connect to this database and then read the multiple tables. Maybe some performance can be gained here, although that wouldn't explain why the database is also slow from the management tools and when used through other applications with a direct connection...

Bind A Text Box To A Field Selected By SQLDataSource (VB.NET)

Feb 8, 2011

I'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.

For example, I have 4 textboxes currently that have Address, City, State, Zip. I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID.

How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.
