I have a listbox that I am populating at runtime with javascript. After the listbox is populated I am using a button to get that value. on button click when I am trying to get the value it is the listbox item count is 0, Can anyone tell what's wrong after t he javascript populates the code,I have written the code in button click :
for (int i = 0; listbox1.Items.Count - 1; i++)
{
string s = listbox1.Items[i].ToString();
}
the value of count is showing as 0, though it has the values populated. What I am missing ?

I'm working on web pages that have an ASP DropDownList defined, and on page load the data source is bound to it through DataSource.DataBind(). When I step through the code, the drop down list does not show anything in it, but when the page actually displays, it does have items in the list. When exactly does DataBind() get applied to the control?
The problem is that some of the values returned by the SQL back end have a null Text, so nothing is displayed in the drop down list for that row. I want to just use the Value as the Text, but only if the Text is null. And when I put the code to loop through and do that right after the DataBind(), there is nothing in the drop down list at that point in the code.
I am not sure if I'm in the right forum but I try anyway.I am making a webproject where I have a database with tables Product, ProductDetails.In my pageLoad event I am retrieving the information from these tabels in two lists: productList and productDetailsList.
Now what I would like to do is to databind these lists in code behind to my ListView. I know how to do this if I only have one list but in my case i have two and in my listView i have fields whose information is in productList list and others in the productDetails list.
Is there a way to achieve this?
Here is some code where I am databinding one List to ListView:

In a website I'm working on, there is a link to ~/Products/1/2%20Inch%20Tube.aspx (1/2 Inch Tube.aspx). As I'm using a fake path the name of the URL is not a problem appart from the fact that there is a slash in the name. The URL safe code for it is %2F, and I use a replace to check for this in my SQL query (REPLACE(ProductName, '/','%2F')) AS Link, and before that in the eval statement (NavigateURL='<%# "~/Products/" & Eval("Link").ToString.Replace('/','%2F') %>'). Sadly when databinding this using an eval to a Hyperlink, the %2F changes back to a / (Slash)
Is there a work around for this or should I just not allow for slashes when saving products.
I am developing a usercontrol which has a gridview control in it.
Now I want to set the datasoruce property of gridview. Datasoruce will be a generic list (List<Class>).
How to do this ?
I have a textbox located at the upper left of my page and a gridvew located at the upper right. However though, once my gridview is populated with data, I noticed my textbox moves from the upper left to the middle left of the page. i am trying to fix thisproblem and do not fully understand how to.
View 2 RepliesCan you databind a caption when using a gridview?
View 1 RepliesWhy is there a need to explicitly call GridView.DataBind() to render the gridview. Why wouldn't it render by itself automatically like how it happens in Window Forms?
View 2 RepliesI have a gridview being populated by an ObjectDataSource (ODS). The ODS is calling a BLL to get information from a database table. The information returned is all determined by a participantID. This works fine normally.
The issue is that I'm getting an exception thrown when the participantID isn't listed in the database table; which is possible until their information is inserted and updated on this database table. The information is entered when someone visits a webpage, their information and date/time stamp is inserted/updated to this table, but not until then.
Do I edit my ODS or the BLL to check for a null return and handle this exception? How would I do this as well?

I have a blank/unbound GridView control on my form and I am binding it in the code behind like this:
GridView1.DataSource = _dataSet
DataBind()
Running this code populates my GridView control with all the columns and data that _dataSet has. I want to display only some of the columns, change the column names, and rearrange some of these columns too (i want the last column from the actual sql database table to be displayed first in my GridView).
I got a GridView in ASP.Net in which a user control is placed:
<asp:GridView ID="GVWunitcollection"
CssClass="gridview"
runat="server"[code]....
I bind the GridView to a List<T> filled with custom 'Unit' Classes. Each Unit consists of several properties to fill the usercontrol. (The user control holds a table, and some labels and textboxes).How can I achieve this? Is there a simple way to bind each usercontrol to the appropriate Unit?By the way, this is my way to mimic a "dynamic" behavior of multiple usercontrols on a page. If there's a more simple way, I would like to know how!
I want bind more than 10000 records in gridview and improve performance.
View 1 RepliesMy issue is similar to [URL] how-to-use-the-value-of-a-selected-value-from-a-dropdownlist-populated-with-ajax but I am using ASP.NET, not PHP. I have a dropdownlist that is populated by another dropdownlist's current value through ajax. So if DDL A is 'NY', DDL B is populated with different data relating to 'NY'. I need that data to be posted back to the server because this affects an SQLDataSource parameter. However, as far as I can tell, the value is always null after postback resulting in the gridview to be empty.
View 1 RepliesMy page includes a button and a GridView bound to a LINQ data object which is bound to a table. when the page loads the gridview gets populated with the data and all work well. The button has an empty method, when I click the button I get en error message "Intenet explorer cannot display the web page" I put a break point at the begining of the method listed below but I get the error message before it gets there. If I remove the gridview than the button works well.

I am having some difficulty enabling sorting on a gridview that has data in it that has come from an objectdatasource.
The AllowSorting="True" function doesnt work for ObjectDataSource so I need to find a work around...I am guessing that I will need to do something in code in order to get this off the ground.
In a webpage in my project there is one textbox and a gridview.
Gridview is being populated by some parameters coming through Request.QueryString from previous.
When gridview is populated a very huge data appears.
In gridview there is one column:
SR status
1425688 pending
2678549 closed
5342875 transferred
What I want to do that in a textbox user type SR number and the row containing search parameter should be selected only.l

The problem is that i need to select, delete and edit itens, but the grid dont recognize the other methods...
I am trying to get gridview populated on the basis of Date as a search parameter.Date Textbox is taking date as MM-dd-yyyy.Date format in table is dd/MM/yyyy HH:mm:ss.The problem is that when I give date for example 30-04-2010, the data is not populating to gridview as the date in the table is 30/04/2010 12:00:00 .Actually I want to know query.
View 5 RepliesI am using ITextSharp to create a pdf. But when I am binding data to Gridview dynamically which was actually a result of ajax webmethod, its showing a blank PDF file. So how can I export dynamically binded data to GridView to PDF. Is there any other way to export dynamically binded gridview data to PDF?
