Forms Data Controls :: Binding Complex Property To Gridview Columns?

Oct 15, 2010

We know that using something like Bind("CustomerName") can be used in the Text property of a label control inside a gridview, where CustomerName is a property of the object whose collection is bound to the gridview. If that property is of a complex type (object of another class), how do we use a property of that inline object as a binding for the gridview column?

DataSource Controls :: Sum Data From Two Columns In Different Tables - SQL Query

Feb 9, 2010

I am trying to create an application in which there is a summary of outstanding payments.

One table is Table_Bills.

The other table stores records of Payments made and is called Table_Payments.

In summary i want to show 3 figures - each in separate one field datagridview with a data_source in separate data_adapter:

1) Ammount_Due 2) Amount_Paid 3) Balance.

The first two are no problem but the last is giving me a headache.

I tried this:

Binding Dataitem To Columns In Gridview?

Mar 17, 2011

<%# ((DataRowView)Container.DataItem)["SomeProperty"] %>
<%# DataBinder.Eval(Container.DataItem, "SomeProperty")%>

From Google i figured out these can be used to bind the columns in GridView to ArrayList. But what is "some property" ?For example i have a ArrayList in .aspx.cs as

static ArrayList componentSelectionArray = new ArrayList();

so can i just write in grid view to bind a arraylist to grid view columns as:

<asp:GridView ID= "GridView1" runat="server" AutoGenerateColumns="true">
<asp:TemplateField HeaderText="ComponentName">

Columns Of Two Related Database Tables In One GridView With EntityDataSource

Feb 17, 2010

I have two SQL Server tables with Primary Keys (PK) and a Foreign Key (FK) linking the two tables:

1) Table "Order"

OrderID, int, PK
AddressID, int, FK

2) Table "Address"

AddressID, int, PK
City, nvarchar(50)

Then I've created an (ADO.NET) Entity Data Model out of those two tables. Now on my (ASP.NET) webpage I put a GridView with an EntityDataSource. In my GridView I want to display two columns:

OrderID City (belonging to that order and linked by the AddressID-key) How can I do that? My problem is: When I configure the Entity Data Source I can select an "EntitySetName" which can be either "Order" or "Address" but not both, nor can I select any kind of relationship. If I select "Order" as EntitySetName
then in the GridView I can add the columns


Adding the column "Address" displays empty cells. Adding "OrderID" and "Address.AddressID" displays the expected IDs. But how can I add the "City" of the related address to my GridView? Edit: Clarification:

The Entity Framework has created a class "Order" and a class "Address" corresponding to the database tables. The class "Order" has a reference to an "Address" object as a navigation property, corresponding to the 1-n relationship between Address and Order table. Basically I want to have a column in my GridView which displays Order.Address.City. I have tried to add a bound field with "Address.City" as data field to the GridView but it results in a runtime error ("no such property...").

C# - Adding Columns And Mid Binding A Dataset For Gridview?

Jul 7, 2010

I am using subsonic in forms C# and I have an instance where I need to loop through a recordset and for each one call the Database to get specific information from a view about that record.

in this instance it is a venue, loop through and for each venue I show there spend and there budget, but I am at a loss as to how I can say use a gridview, execute more code on each row and then add more columns to that row.

just as an update i have been playing with the idea of something like this:

DataSet ds = new DataSet();
ds.Tables.Add(LinqToDataTable(club.All().Where(x => x.level == 1)));
ds.Tables.Add(LinqToDataTable(ViewBudgetSpend.All().Where(x => x.periodfrom == curperiod)));
DataRelation relation = new DataRelation("budgets",ds.Tables[0].Columns["clubId"],ds.Tables[1].Columns["clubid"]);
still working this out though.

VS 2008 Hiding Columns In Gridview After Binding All Rows?

Jul 22, 2010

I am trying to set come columns to invisible after all of the rows are binded but I'm having trouble. I'm hiding columns that have empty data which I save in a session variable. This works fine. Then I tried changing the columns visible property using the ColumnByName routine in the DataBound but that must be the wrong event because I do not think the columns exist yet.

The columns are autogenerated btw.

Where can I set the columns properties after it has binded? Can i do this before the columns are autogenerated the the screen itself?

Changing The Order Of Columns When Binding DataTable To A GridView

Mar 31, 2010

How is it possible to change the displayed order of columns from a DataTable?

For example, dataTable "dt" contains two columns "a" and "b". I bind it to a GridView like this:

gridView.DataSource = dt;

But I'd like the GridView to display "b" first (leftmost).

Important point: I'm using this to export to Excel and there's no actual output to screen, using:

HtmlTextWriter htw = new HtmlTextWriter(sw);

ADO.NET :: Compare Columns In Two Data Tables

Dec 3, 2010

is there an easy way to compare two columns in two datatable to see if they match? I need to check if the values in column["x"] of datatable1 occur in column ["y"] of datatable2, without iterating through both tables (for each value in column of dt1, check column of dt2). I tried:

foreach (DataRow dr in dt1.rows)

if (dt2.rows.find(dr["x"]) but this checks the whole row and if finds an "x" in any column, "if" condition is true. I need to only check one column of dt2. Tables have different columns but the same primary column and that's what I need to check

SQL Server :: Add New Columns (with Data) To The Existing Sql Tables?

Jul 14, 2010

I have two sql tables.

- (Fields:PersonID, FirstName, LastName, Role, Department)


- (fields: PersonID, Unit).

I want to merge those with a single table ( Fields:PersonID, FirstName, LastName, Role, Department, Unit). How can I query to accomplish this so that same personID data go to same row ? ANY QUERY ?? (I have an idea : both export to excel and merge into a single excel file and import to SQL table but due to very long data it was truncated last time when importing so I don't want to reimport again.)

Forms Data Controls :: Gridview For All Tables?

Sep 30, 2010

I have a task to create grid view for 8 different tables. I am wondering if there is a better way to create those gridviews. The following features has to be in almost all 8 gridviews

1. Add / Edit / Delete / Sort
2. Some of the grid view has to contain a combo box when editing the row
3. A check box has to be in first column of the gridview
4. When editing the grid view, I need to have an edit form pop up
5. Confirm delete dialog box has to show before delete.It is not smart to create 8 grid views ( I am trying to avoid creating the grid manytimes)

I get the error "
