Data Controls :: Retrieving Wrong Data
Nov 20, 2013
I am making an application that generates P.O automatically after entering all the details prices, taxes, descriptions ..
I have used the following code for retrieving the the float type amounts.
Double Price1 = 0;
bool isPrice1Valid = false;
isPrice1Valid = Double.TryParse(TextBox8.Text, out Price1);
if (!string.IsNullOrEmpty(TextBox8.Text) && !isPrice1Valid)
[Code]...
The data in the databse takes null values which are left over while submitting the values..as in the empty textboxes are saving as zeros..
It is atchually a mess when data is retrieved. I retrieve the data using this code ....
TextBox10.Text = reader["Amount11"].ToString();
TextBox24.Text = reader["Amount12"].ToString();
TextBox31.Text = reader["Amount13"].ToString();
TextBox38.Text = reader["Amount14"].ToString();
TextBox45.Text = reader["Amount15"].ToString();
[Code] ....

I have a weird thing happening. I have two identical databases installed on one virtual machine but under two different instances of SQLServer. For some reason, periodically when saving from one it will save to the other instead. Using debug, I have verified that the connection string is correct and when the item saves, it still saves to the wrong database.I use session variable, and am of the belief that it might have something to do with it...and t hat when I go from one to the other it is still getting the connection string form the other for some reason.To make sure that it isn't a problem, I make sure that I completely close out one database before opening the other in a new IE window.I assume that when I completely close out an internet explorer window that it abandons all session states. Is that true?

I have a very weird thing happening. I have two databases that have exactly the same tables but different database names on the same virtual machine, but in different instances of SQL Server. For some reason, when using one of them, it will save to the other. In debug, looking at my connection string..I have verified that it is correct, yet when I allow the save, I look in the table and it isn't there, it is in the other database that is in a table with a completely different name and in a different instance of SQL Server.

I have a datasource:
[Code]....
I have a detailsView bounded by some other datasource. There is a dropdown in detailsview which is bounded by sqldatasource named "sdsNature" . Here is the templatefield for dropdown:
[Code]....
I want to show FNature instead of FNatureID in the selected mode as Label and in Edit mode as dropdown. When I am running this project, in Select mode it is showing FNatureID instead of FNature and if I click to Edit the record it is displaying following error:
'lstNature' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value Do I have to give some If else condition that if FNatureID is .... then dropdown should display FNature.... If yes then what should be the code?

I am retrieving data from a web serivce and storing the data into a dataset.
I'm then populating a gridview with the data from the dataset.
Before each row of data is displayed on the website, I need to check and make sure the user has proper permissions to view that data.
Can this be done with a gridview(or any other .NET data control)?
Or would I need to loop through the data manually, and then write each row out manually?

I have a search option which a person can use a multi select listbox. I have it coded so it would loop through to see if its selected or not. I also have a stored procedure where the sql statement is coded for the select statement. For some reason, its not populating my gridview. Where am I doing wrong? Below is the code and stored procedure.

I am somewhat new at C# so forgive me if I have something listed wrong. This is what I got:
I am working on a school project designing a car dealership website. I have an inventory list that allows you to edit any car in the inventory. When you click on the edit button it takes you to the edit page and populates the controls with selections from the database. I have an options table that stores the VehicleID and Option ID. When the page loads it fills all the DropDownLists for the vehicle info with the data and selects the correct item according to the database selection but the CheckBoxList does not select the items that are on the Options table. I checked the query in SSMS and it returns the correct data. I have stepped through the method and it works till the "(currentCheckBox != null) if statement. It doesn't throw any errors but it also doesn't select items when the page renders.
I thought it might have been something with the page life cycle since databound controls don't render until the end but the DropDown's I have fill and selects the correct item according to the database.

I've created a data bound gridview to a SQL database. I am retrieving the data with a simple select for a specific date, and then populating my gridview. The one caveat is that I have added a second header row to my gridview, and then I am hiding parts of another row that was retrieved to only populate the main header row. I believe that this is causing my issue. However, when I step through the code it appears that my ids are proper (the first row has an id of 0, etc....). However, when I check the checkbox in row 4, the actual data from row 3 is being pulled out of the gridview.

I'm in the process of developing a survey system. The tables / fields that are related to my question are:
[Code]....
My issues with this way were:
1) The Data Adaptors receive ALL the records from their correspondent tables. Not a good practice, I believe.
2) If, at some point, the survey had no categories, questions or choices under its child records, an error occurs when the page tries to build the Data Relation. With the work flow I had in mind for the system, this is bound to happen becuase all the Data entry pages (Add Category, Add Question, Add Choice) will be displaying the newly-created survey in a similar fashion (at which point, the survey will have no child records and so an error would occur)

If I have the ListView on a mode which only displays data (no editing or inserting), how do I reference data in a list view item using the code behind?
In other controls I have used e.Items and e.Values, but I can't seem to work out how to do it in the listview.
For example if I wanted to set the image based on a database column (I know I can do this in the HTML but just for the purpose of the example, what would I put in place of the *** below:

I have a ListView that populates and displays a user's data (via a profile system in VWD 2008) during Page_Load and also when I go from the EditItemTemplate to the ItemTemplate.
When I go to the edit screen again, my DropDownList and RadioButtonList controls display the first items in the corresponding tables instead of the correct profile values.
I don't understand why the controls populate correctly the first and second times but not on the third time (that's right, the third time is NOT a charm).

I have a page with a gridview. It has a select command and an edit command which are both SPs. I added a standard "Edit, Update, Cancel" CommandField to the gridview so that I can edit. The edit and update are working fine. However, I have found that if the underlying data changes after I have loaded the page and before I hit "Edit", and this change causes the row I'm going to edit to be in a different row than before, the gridview will open the wrong row for editing.
For example, say the gridview is sorted by the a field called ID, and currently there are rows in the DB with ID of 2,4,6 and 8. I load the page and see those 4 records. While I'm looking, someone adds a record with ID of 1. When I click Edit on the row with ID = 4, I will actually end up editing the record with ID 2. Basically, i'm clicking on Edit in the second row, and I end up editing the record in the 2nd row, but the 2nd row is now a different record than before.
It seems like there HAS to be a way to fix this, otherwise editing in the gridview seems exceptionally dangerous. Is there any easy way to handle this, to make sure the user is editing the row they think they are?

I'm using a GridView and GridViewHelper Class [URL] for grouping the grid by desired field. On the grid I also include an "edit" RowCommand.
Example:
ID ... Name ... Company ... Year ... RowCommand
GROUP1
1 ... Alex ... Comp1 ... 1999 ... Edit
2 ... Jane ... Comp2 ... 1999 ... Edit
GROUP 2
3 ... Mike ... Comp1 ... 1999 ... Edit
Now when I click edit in the second row of the grid (ID=1, the Group itself is shown in the first row) I have the following code on RowCommand:
[Code]....
and the index returned is 0 instead of 1. Why? And how can I fix this, because the edit command returns error or points to the wrong records??

I apologize in advance for my poor english:1. I have a dropdownList within my datagrid and its already populated fine (22 rows in my datagrid)2. The select item for the 21 row is the same as the select item of the 22 row3. When trying to do selectedIndexChange for the 22 row, it didn't seem to work.The error:
Dim ddl As DropDownList = CType(sender, DropDownList)
Dim dgi As DataGridItem = CType(ddl.Parent.Parent, DataGridItem)
Dim rowID As Integer = dgi.ItemIndex
The rowID keep staying at 20 even though the selectedIndexChanged is happening in row 22( ie. rowID should be 21)
