i am fetching data in a dataset.now i m trying to modify the contents using :
For Each row As DataRow In ds.Tables(0).Rows
If row.Item(7) = False Then
ds.Tables(0).Rows.Item(6) = "`/abc/xx/" & row.Item(0)
End If

I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
i have this xml file which i read using the DataSet.ReadXml( path ) method . The tables created from the Xml file is Related in such a maner that each product has many options. Product is in one table and Options are in another.Now all i want to do is display the related tables in One Gridview. For your reference below is the products Xml file,
[Code]....
Now this is what i have done in the Code behind , have a look below
[Code]....
Now the Grid works Great if i want to Display Individual tables out from Dataset but not when they are related . Please do shine your Knowledge on what should be done to display Child ~ Master relationship. By the way , its a definite NO for someone who would show me that link from msdn about displaying XML data using Xmldatasource and gridview [That's a lousy way to display data]

I have webpage with three dropdown boxes on left side (Country Dropdownbox, State Dropdownbox, City Dropdownbox) and these dropdown works independently or one box will depend on another. I have a gridview in right side and the results will be binding to the gridiew by selecting the left side dropdown boxes.
I need to implement the caching technology here because the web page loading very slow due to large amount of records. For example if i select any country from the first dropdown box and the other two boxes are default (Selected text is "ALL"), then It should display records related to selected country in gridview.
Further if I select country and state from the respective boxes then it should display the related records in the gridview like so on. Now i want do some caching functionality to improve the performance. I tried caching the Dataset while binding to gridview but in my case the results will not be static becasue user every time will select different options from different dropdown boxes and results will come based on the selected options.

I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.
in the code below, the string sFoodFormReceived1 always gets today's date. I dont know how to make the date clicked on the datepicker bind to the textbox in the gridview gvReservationsWithForms.

I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

I am using subsonic in asp.net 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"]);
ds.Relations.Add(relation);
still working this out though.
I have a gridview which has editable columns.
The gridview lives in a formview, which lives in another formview.
Inside one column is an end date. This column has a textbox which gets it's value when I choose a date from a calendar control. However, when I choose a date from the calendar control, the program crashes instead of populating the text box.
Here is the page and the selectedIndexChanged sub for the piece of work I'm trying to accomplish...

I have a databound gridview using datatable as datasource. Template fields are used to edit the row content.This cell value should get updated in the datatable on text_changed event without using gridView edit. Is it possible to overload the GridViewEditEventHandler for this purpose.
View 3 RepliesI ahve displayed a group of data in my gridvew with the edit option linkbutton template field for each row. The gridview columns consist of employee name and projectname and total hours field employee worked.
So in this when i click the edit button using the datakeynames alue for project name id and employee id ,i have to redirect the page to another page with the values in the grid for the particular employee.so that i can update the totalhours field in the redirected page.and if i press the update button in that page then the page should be redirected to the gridview page with the updated value for the particular employee and project. The page which should be redirected consist of project name dropdownlist, module field,date field and total hours field. No employee name field.
Using the gridview rowdatabound field i have postbacked the url page with the project name id but it does not displays the project in the redirected page.And employee name i have to redirect with the session value i think?

Every row in the gridview has an edit hyperlink, so when I click that, I can change the values in that row using a dropdownlist, wherein, the item in my dropdown are aswell from my database.
