I have a Gridview which I'm populating through code behind. A couple of columns of the gridview I've set up to be drop down lists. What I want, is that when I run my Insert query, it takes the drop down list selected value, finds the appropriate ID and uses that ID as part of the insert query.
Below is my select and insert query.

I thought this one would be easy, but no go. What I am trying to do is the following: I have two DropDownLists in my InsertItemTemplate, each bound to its own datasource. After the fields in this form have been filled out and the ItemInserting event fires, I rebind the ListView to its datasource, but the DropDownLists turn out empty. I tried to bind them in the ItemInserting event and it seems they get filled, but nothing shows up in them when the page loads. I also tried to fill them in the ItemDataBound event, but the e.Item.ItemType == InsertItem doesn't do it.
How can I fill those DropDownLists?
I have a gridview with column name:
Pending, Waiters, Opened
and in the rows under column there are figures like:
30, 50, 28
65, 0, 214 etc.
My program is working fine, when I am clicking 30, a new page opens and displays 30 rows, when I click 28 another page opens and displays 28 rows and so on.
In datatable there is a column named Stauts, actually Pending, Waiters,Opened are the status.
In dataset in table adapter I used thress queries one for "Pending", second for "Waiters" and third for "Opened".
To display data I created three pages with gridviews.
I used query like:
Select * from ..... Where status ='Pending'
Select * from ..... Where status ='Waiters'
Select * from ..... Where status ='Opened'
What is Required:
I want to make one query with status =@status and want to use header name in query or in vb.net coding and want to make only one page to display record.
To put my question as an idea/example I used three status but in real scenarion I have lot of status. If I have lot of status so I have to make lot of queries and have to create lot of aspx pages to display data in gridview that is not the correct logic.

I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table....

I am using a dataset control and I have 5 dropdown lists in which their content depends on what item is selected in each dropdown list.
I know I can populate the lists with 5 different queries taking the variables from each list but I am thinking there must be a better way.
Is there a way to populate each list with one query that takes the distinct items from each column returned without looping through the entire recordset?
I have a ddl inside the formview that I can't figure out how to wire up properly. The formview contains detail info, but the ddl needs to list the entire set to items.

I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!
Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.
I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?

I have developed the below web page which has an asp.net 3.5 listview control as it's frontend and an sql server db as it's backend.
[URL]
The first row on the web page is the inserting row. What I am hoping to achieve is that when the user enters their appropriate data they click the "Next" button to assign this dataset with it's own identity ID (customer_id) value within my database (this works perfectly), at the same time on the fly I want to use this customer_id as a query string variable to populate a child page (customerTrades.aspx) in order to pin further data to this identity. Currently I am attempting to use the below code within the iteminserted event of my listview control but I receive the error: "object reference not set to the instance of an object"??
protected void lvTrustAccounts_ItemInserted(object sender,
ListViewInsertedEventArgs e)
{
string customerID = e.Values["customer_id"].ToString();
Response.Redirect("http://www.tradeselector.co.uk/customerTrades.aspx?customer_id="
+ customerID + "");
}
Is this because the child page cannot find the customer_id variable being passed through the query string? Because it's not actually created yet? Am I using the wrong listview event? How can I achieve what I am looking for?
I must also mention that I'm using a linqdatasource to insert my data on runtime into my database. However, I am using the listview iteminserting event to insert my frontend dropdownlist selected values, code below:
protected void lvTrustAccounts_ItemInserting(object sender,
ListViewInsertEventArgs e)
{
e.Values["customer_created_date"]
= DateTime.Now;
e.Values["customer_update_date"]
= null;
DropDownList ddl_CountyInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountyInsertDDL");
DropDownList ddl_CityInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CityInsertDDL");
DropDownList ddl_CountryInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountryInsertDDL");
e.Values["customer_county_code"]
= ddl_CountyInsert.SelectedValue;
e.Values["customer_city_code"]
= ddl_CityInsert.SelectedValue;
e.Values["customer_country_code"]
= ddl_CountryInsert.SelectedValue;
}
So I have a dropdownlist and I'm trying to populate it with values in the database. For some reason, half of the rows has no value. It's happenning in a sequence as well, like the first row has no value, then the second row has value, then the third hasno value....
Does any one know why it does this?
