In ASP.NET I have a dropdown with some items in it, I have a button and a textbox. I am subscribed to the SelectedIndexChanged event of the dropdown where I pass the new selected index of the dropdown to a struct that converts it's index (via enum) to a string. That string is then gotten through a property in a class to put into the textbox.
[Code]....
Now the problem I have is that, when you click it (the button) the first time, the action get's updated with the current action selected in the listbox, but then when you click the button again WITHOUT changing anything in the listbox, the textbox shows the zero'th item in the textbox, (seems to reset), although it actually hasn't changed at all.
I'm guessing this might have something to do with the postback caused by the button click, which resets the state of the global or something, but I'm not sure. Why is it being reset while the dropdown box is still as I set it the first time?
I have been trying to figure out what the proper method is to be able to have a dropdownlist on the same form that holds a number of textboxes for properties. I am using a strongly typed typed view which was generated by the Visual Studio IDE so it contains textboxes for all of the properties of my strongly typed class. The class has a few properties that can have a set of possilbe answers; I'd like to displat those possible answers in a dropdownlist and then when the user fills in the form and clicks the submit button the selected item would be transferred to the correct property. I have a solution but think there must be a better solution out there and was wondering if anyone might point me in the right direction.So say I have a model with 3 properties, FirstName, LastName. and MaritalStatus.If I generated a view for this then I'd get an aspx file with the following:

I wanted to know if it is possible to pass multiple selected values from Checkboxlist to SQL table so each selections goes into separate row in the table.
I tried it using the following code (to pass ShowDate value) but it enters value only if I make one selection. It gives me an error message if I make two selections and try to pass it to SQL.

I am using CreateUserWizard control where I collect personal information from the user on the first step (ie. name, address, tel, mobile etc) then on the second step I collect information for membership service (ie. user name, password, email etc). When user clicks Create button, information is sent to two different tables in the same database. Everything works fine but one.
In the first step where I collect personal information, I also collect details about Interest which is a CheckBoxList (CheckBoxList is getting values from Interests table: 1-White, 2-Green, 3-Brown, 4-Maroon, 5-Yellow).
What I want to do is, when client selects his itnerest categories and clicks Create button, to send selected values from CheckBoxList into the third table called Categories. I want values to be registered into the CatCode column in Interests table as comma delimited. For example: if client selected "White", "Green" and "Yellow", appropriate values for those interests (such as 1, 3, 5) to be registered under Categories table CatCode column (like: 1,3,5).
Following is my code:

I have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?
If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.
I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

And here is imagebutton code that when click on it update data into table
protected void ImageButton_Click1(object sender, ImageClickEventArgs e) {
string data = Server.UrlDecode(Request.QueryString["BehCode2"]);
SqlCommand _cmd = new SqlCommand("insertinfo", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();

Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load

And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.
I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
i use a dropdownlist in a page, with its items taken from a mysql database
i also use autopostback property...my problem here is that, every time i selecct an item, the first item in the list gets seelected
How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.
I have a drop down list control populated with items and some code to take the currently selected item value. The problem is I only get the value of the first item in the list regardless of what item is actually selected. Here is my code to populate the drop down:
protected void displayCreateCategories()
{
StoreDataContext db = new StoreDataContext();
var a = from c in db.Categories
orderby c.Name
select new{catName= c.Name,
catId=c.CategoryID};
ddlCategory.DataSource = a;
ddlCategory.DataTextField = "catName";
ddlCategory.DataValueField = "catId";
ddlCategory.DataBind();
}
To get the value of the currently selected item which in my case is always of type integer I do label1.text=Convert.toInt32(ddlCategory.SelectedValue); I get the selected value, but it is always for the 1st item in the list. I'm pulling my hair out over this.
i have added one textbox as a template in my gridview.i want to get the values of textbox to a string when i enter values to the textbox.
View 1 RepliesI have a site where users can save images together with a couple of info fields about the image. The images are stored as binary data in the same table as the rest of the image info. So far pretty standard.
Now, the users should be able to upload a document, describing the image in more detail, along with the rest of the image and its' info. Size ~2MB per document.
My question is: Should I store this document (binary data) in the same table as the rest of the images or should I create a new table holding only the documents. There would of course be an id reference in the image table to the document in the document table.
I have a search function joining a couple of tables, including the image table, when searching for images. I need to know if there's a difference in efficiency between these two solutions. I always fetch the document data separately but if I don't win anything in having the documents in a separate table I'll just put it with the rest of the image info.
I'm asking this since I don't really know how SQL Server handle tables when joing and searching in them.
I have about 10´000 users with a maximum of 10 images per user. (ASP.NET - SQL Server) (I'm not asking if I should store documents in the database, but how ;)
Edit
Example 1:
columns in imageTable - id, title, dateAdded, image (binary data), document (binary data)
Searching for items from a specific user I would join the userTable and the imageTable and select title where image id equals user id.
So, will there be any difference in the performance if the document is in the imageTable or in an own table?
i have the following two questions:-
1. let say i have a table for ITEMS including (item id,item description id (FK to the ITEM Description tabe), item price,etc) and have ITEM Description look up table having (item descriptionid,item description),.
so what is better to use the ITEM DESCRIPTION look up table and store the item description id in the items table
or
to directly store the item description "Not the id" in the item table.
2. I am working on an MVC web application using LINQ, now if i want to modify the SQL server tables which i have created for example modify some of the foreign key properties will the effect be directly reflected on any new inserted or deleted records or i have to create a new LINQ to SQL class?
Values in multiselect dropdown not getting selected when Select All option is selected for a SSRS dropdown. There are multiple dropdowns on the page. We have one dropdown whose output is being used to populate the second dropdown using a stored procedure. When we check the Select All checkbox on the dropdown then ideally upon page refresh all the values should get selected in the dropdown, but in this case the page refreshes back to the blank dropdown, forcing the user to select the values again. The next dropdown too does not get populated. This makes it impossible to run the report for all the cases by using Select All. We ran the report on differnet database environments. My current location is Mumbai,India, the report worked fine when we ran it on a Bangalore,india database. This issue occurs when we try running it on a Chicago database server. I am using SSRS 2005, SQL2005.

SubjectFilter.DataSource = b.BooksList.Select(x => x.Subject).Distinct().ToArray();

Everything loads just fine. However in the SubjectFilter_SelectedIndexChanged method, SubjectFilter.SelectedValue is always Default, even though I'm selecting different options.
I would like to store some business flags (like: isFavorite, isOnLive etc.) per an html table row that won't be visible to user.
In practice, I have a simple ADO.Net DataTable on my code-behind which is used as a data-source for a asp.Net GridView control.
This table contains some business flags on its 0th, 1st, 2nd columns.
I need to store those columns on the rendered HTML of the grid-view -so that I can reach them via JavaScript- but I do not want them to be visible.
