I have a Detailsview grid with an SqlDatasource, this DVG is only going to be used to insert records. The primary purpose of the DS is to populate a DDL control in the insertItem Template that I created my code is this:
[Code]....
The DDL control populates correctly, but when I try to modify the INSERTCommand property in my DS, I try to assign the value to my parameters "TesterID" and "TesterDate" but the only options for controls to pick from, is the DGV but not the DDL in it. I assume it has to do with the InsertItem template but even if I reset it I still cannot pick the textbox as a control that would give the value to my parameters.
I did find a workaroun by build a public method and calling it in the onclick event of the insert button but looks like I have to create another connection to the database which to me seems unnecessary since I already have a DS and everything. how can I do this without having to use my method. here is my method just in case.

How do I get the "NewID" parameter value form the above datasource and assign it to a select parameter in a different sqldatasource?
I am looking to cache a dataset and then filter the results as they will be used repeatedly. However, I don't know how to assign values in the filtered dataset to variables in C#. I have looked on the internet for the past few hours but all I can get in binding the dataset to a control.

i have a datatable with several columns and rows. now i want to copy the last column fully (all rows) and create the new column with that values.
it means last column values sholud be moved to new column (now this is the last column).
I am looking to retrieve data from a database and assign those values to class objects which in turn will be turned into session variables. I am using an object datasource to retrieve the data from the database but I cannot find anywhere that shows how to assign these values to variables. The data is returned in a dataset. There is the added problem that there will be mulitple items returned which will have to be assigned to different arraylists of objects based on the a primary key in the database.

I have 3 tables as follows:
1 - Members containing the following fields:
MemberID int
MemberName
2 - Companies containing the following:
CompanyID int
CompanyName
CompanyType (S=Supplier, R=Retailer, C=Competitor)
3 - Member_Company_Link containing the following:
MemberID int
CompanyID int
The Company table contains any Company with a potential relationship to a "Member". For example:
Companyabc = C (Competitor)
Companyxyz = S (Supplier)
When a new Member record is entered, the user selects from two dropdowns: CompanyType (Supplier, Retailer,Competitor); and CompanyName. The CompanyName dropdown is populated depending on the value selected for CompanyType so if the user selects "Supplier" for CompanyType then only those Companies with a CompanyType of "S" for Supplier will be listed in the CompanyName dropdown.
The use can enter up to 10 CompanyType/CompanyName combinations. When the record is saved, these CompanyType/CompanyName combinations are saved in the Member_Company_Link table. One record for each CompanyType/CompanyName combination is entered in the table.
The problem I'm having is in the retrieval process. I have a "search" screen in which users can select certain criteria to list Members by and one of them is CompanyName. For example they want to see all Member records with "company xyz" as a Supplier and/or "companyabc" as a Competitor. Because each Member can have multiple Supplier and/or Comptitor records I can't figure out how to loop through them to match on the value entered by the user. If Member1 has 5 corresponding records in theMember_Company_Link file and 4 of them contain Companies that are Competitors (Competitor1, Competitor2, Competitor3 and Competitor4) and the search criteria is to find records containing "Competitor3" how can I loop through the values in the Member_Company_Link file for each MemberID to see if there is a match for "Competitor3"?
I know this post is too long and most of you will have ignored it by now but I'm hoping someone will have a clue because I've already spent more than a day trying to figure it out. It seems I have to store multiple values in an array but I have no clue how to do this.
Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I have successfully created a strongly typed dataset. And trying to assign my user input values to the columns of my StronglyTypedDataset but having no luck with it
[Code]....
In the above code 'PlantInventoryAccuracy' is the name of the Strongly Typed Dataset and 'PlantInventoryAccuracyDataTable' is the dataTable. when I try o debug this to see if my user input values are being assigned to te currentRow I see blue squuiggly line under the 'new' key word when I mouse hover it says
'The type PlantInventoryAccuracy.PlantInventoryAccuracyRow has no constructors defined.'
This is the first time I am trying to use Storngly typed datasets. I am not sure if I am trying to use it right. The above code is in my code behind page and my idea is to fill this row with the user input values then pass this to my data layer where I need to assign these values as the parameters to the stored procedure I have created and then store them to the database.
i dont know why this happens and when happens......i have one employee table that contain date field and that field contain two different values one is -'2008-10-01 00:00:00.000' and second is '2008-10-01 12:00:00.000'.can anyone explain when this type of value insert in database.

how do i multiply the columns like this. for now static explanation would be ok but eventually i would like to make it dynamic so there would be a text box for users to enter the amout they like e.g 160g then the table would know to multiply the columns by 1.6.
i have 3 columns in database table. like below

the input is not coming separately it is mixed of one string with space of string.
but see Address is = Hyd tg is one string how to seach 3 column values in one string input.
I have req where i have to check the value coming from db is null or not and assign value according to that.Problem here is the field datatype is 'Datetime' so all the time when I tried to use the below line of code its giving me error.How can I pass a null value to datetimefield if value coming from db is null.
(reader["FieldName"] == DBNull.Value) ? string.Empty : (DateTime?)(reader["FieldName"]);
I came to know that string.empty is making problem,what value we can pass instead of string.empty for a datetime column in C#.
What I want is ,Field value will get null value assigned not zero.
WHEN I USE IS NULL VALUE DIRECTLY INTO MY QUERY IT WORKS GREAT BUT WHEN I TRY TO ASSIGN IS NULL VALUE FROM A PARAMETER ITS WORKING BUT NO ROW RETURN.MY SP LOOK LIKE THISITS WORKING

Is this the best way to do it having a guid in the table and does this have to be the primary key
I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.
When page loads,I get error - Specified cast is invalid!
The code is as follows...
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="dsResults"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" OnRowUpdated="GridView1_RowUpdated">
<Columns>
<asp:TemplateField HeaderText="COMPLIANT" SortExpression="RESULTS">
<EditItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("RESULTS") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("RESULTS") %>'
Enabled="False" />
</ItemTemplate>
</asp:TemplateField>
Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.
Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.
I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.
I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.
Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.
how i can edit and update Checkbox.
where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.
I have a gridview in a page, and some Texboxes along with a button(for issuing a command) in the same page. The TextBoxs were inputted values and the values could be assigned to the selected row of the gridview, some fields are the same values along the rows, and the values are inputted in the TextBoxes for using several times without change.
Well, I need to know: how can I assign the values of the TextBoxes to the selected row of the gridview. in another words, how can I access the cell members of the gridview when it is in edit mode? (Q1)
If the row is not selected, I have no way to know which row should be assigned values, since there is no such things like "current row".
So, if the selecting button(or link) of the gridview is not selected, the button along with the TextBoxes should keep disabled, until a row's "Edit" button is clicked. (Q2: How can I find if the Edit button is clicked? I guess I can use the property "mode" of the gridview to indicate the situation. )
And the last question is (Q3), how can I ensure the values are updated to the database? Maybe I dont need to do more things than just click the uppdate button of the row of the gridview.
