XML Dataset Form For GridView?
Feb 4, 2010
I want to use an XMLDataset control to read some XML data I have and display it in an ASP.NET GridView control. My data is formatted like this:
[Code]....
When everything is assigned and the page is rendered the GridView component is confuesd and cannot seem to identify the columns and data. But when the data is formatted like this, it works fine:
[Code]....
This is my question: How do I have the XML Dataset Control correctly read the XML data in my first example and display it properly without changing its format?

I'm a bit new to VB .NET programming. I was given a project to build a web page for our Shipping department to pull up some order & invoice numbers, based on an order number parameter.
Basically, what I'm trying to do is, when the user enters an order number, I want the web page to display the invoices & invoice dates that are associated with the order number.
I've put together some code already, but not sure it is actually working. The web page comes up in Debugging mode and it acts like it is pulling data from the Oracle database, but nothing shows up in the Gridview (which I bound to the dataset... I think).
[Code]....
Being new to VB, I'm guessing my code may not be totally correct. I've tried lots of things and done tons of searching on Google, but nothing I've tried seems to work. At this point, I'm not even sure if the dataset is being populated correctly or at all either. I'm a bit lost right now and could use some expert thoughts.
In case it helps, my dataset has one data table in it (dtShipData). My dataset class is sdDataSet. I added 3 columns to the data table and the gridview, manually. Not sure if should do that or not. I don't have any SQL behind the datatable itself...

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:

Should i use dataset in code behind or SqlDataSource on the form designer to fill or bind a DropDownList in my asp.net page I am currently using SqlDatasource on the form and i bind the control to MySqlDatasource because i find it is very easy and to much faster but somebody told me to use dataset from code behind because of security and performance

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();
And conversely when it's time to submit.
formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.

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.

Till now I used to design RDLC file before and assigned typed dataset table columns.Report processing mode is local. But now my stored procedure returns different columns based on condition i.e columns are not fixed every time. Now I need to add that columns to typed dataset and dataset is assigned to RDLC file. So dataset and RDLC files are create dynamically based on stored procedure result set columns.

What I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.

I am working on a page to let a user import an excel file into our database. I want to allow the user to manipulate certain fields before committing the information so I loaded a DataSet from the Excel file and bound that to a GridView. For some reason on rowUpdate my NewValues collection is empty. Here is my GridView:
<cc1:WWGridView ID="gvImportDisplay" runat="server" CssClass="grid-view" AllowSorting="false" ShowHeader="true"
AutoGenerateColumns="true"
AutoGenerateEditButton="true"
OnRowEditing="gvImportDisplay_RowEditing"
OnRowCancelingEdit="gvImportDisplay_RowCancelingEdit"
OnRowUpdating="gvImportDisplay_RowUpdating"
>
<EmptyDataTemplate>0 results found. </EmptyDataTemplate>
</cc1:WWGridView>..............................

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 to which i am adding rows dynamically at the click event of a button placed in gridview footer template. When i want to update data. I have to load the gridview with all the rows required. I get the sql table data in the dataset object and then i have to load this in the gridview. How can i do this? Only one row gets loaded when i use this code:
DataSet DSContact = DMLObj.Load_DataSet("Usp_LoadData", "ContactPerson", idf); foreach (GridViewRow row in GVContactPerson.Rows) { ((TextBox)row.FindControl("txtContactName")).Text=DSContact.Tables[0].Rows[0]["ContactName"].ToString(); ((TextBox)row.FindControl("txtemail")).Text = DSContact.Tables[0].Rows[0]["ContactEmailID"].ToString(); ((TextBox)row.FindControl("txtmob1")).Text = DSContact.Tables[0].Rows[0]["ContactMobile"].ToString(); Session["contact"] = ((TextBox)row.FindControl("txtContactName")).Text; string pid = Convert.ToString(DMLObj.getid("Select ContactPersonID from tbl_ContactPersonDetails where ContactName='" + Session["contact"].ToString() + "'")); Session["contactID"] = pid; }

I am facing problem memory leak when I bind GridView to my dataset. The dataset will be retrieve when page first loaded (Not postback) and store into session. ANy postback will reuse the dataset from session.
The problem now is, whenever any postback, the memory leak is keep increasing and till 1GB. I read some articles and mentioned it is ASP.NET databind issue. Is it true? Any workaround?

Just looking for some strategies to modify the typical
mm/dd/yy 00:00:00 to simply
mm/dd/yy of a datetime item being returned in a dataset that is bound to the gridview
the item is within a dataset and I am simply doing the following
gridview.DataSource = GetDataSet();
gridview.DataBind();
So I don't have a ton of interaction with the dataset at the moment. I could brute force iterate through it and do something like
foreach(Table)
foreach(Row)
grab date Col, format and concat to look as desired
but this is very messy and was wondering if there is a more elegant solution.

gridview.databind();
this works fine
but i when i am using LINQ it gives me result in the form ISingleResult so can anyone tell me how to get a dataset from a girdview after assigning data to gridview
I need a functionality something like :
Dataset ds= new Dataset();

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.
