I have a gridview thats being populated from an excel file that is loaded through a fileupload control. I want to save the contents of that gridview to a table in my SQL database. I've searched the web and tried to loop through the gridview, but failed at it.
View 4 RepliesI have the following code to 'save' a GridView on a page as an excel file, but it pops up a dialogue screen asking the user to view or save.

Refering to your article on exporting the gridview to Word/Excel/PDF/CSV, I modified to code to populate the GV dynamically coz they have different data and different columns as per the selection. But after the data population, when I try to export the data it does not export any data instead for eg. in Word it just export <div> </div>. The code is pasted below.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim dt As DataTable = GetData()
Dim dcol As DataColumn
Dim bfields As BoundField
GridView1.Columns.Clear()

how to save record in GridView into SQL server?
View 5 RepliesI am creating a SSIS package, where I am getting all the data into the excelsheet1, which is not formatted.
So i created a formated excelsheet2, where i am giving reference to excelsheet1 cells reference.
And I am sending email by attaching excelsheet2.
I am having issue when the data is updated, but my email attachment excel is showing old data. When i open the excelsheet1 it is being updated. I don't know why excelsheet2 is not updated automatically. I am using BIDS 2005 .
We have a web application that allows users to upload sales information in Excel format and store the information in our SQL server. The way it works is that the uploaded Excel file will be stored in a folder on the web server, the application will then open it up and read it row by row, and call a stored procedure to store each row's data. Now it is so slow that if the Excel file contains more than 75 rows of data, the application will just time out.
We have already increased the timeout limit by changing the executionTimeout to 300 seconds in the web.config file. Instead of increasing this further to wait for this slow process, I'm wondering if there are ways to speed it up. Is there a better way than calling the stored procedure row by row?
I have code to export the grid to excel . i have taken it from [URL] now i want to save excel file directly without asking user to save it or open it at client side. i want to save it on server folder. how to do that .
View 2 RepliesI am having some difficulty enabling sorting on a gridview that has data in it that has come from an objectdatasource.
The AllowSorting="True" function doesnt work for ObjectDataSource so I need to find a work around...I am guessing that I will need to do something in code in order to get this off the ground.
In a webpage in my project there is one textbox and a gridview.
Gridview is being populated by some parameters coming through Request.QueryString from previous.
When gridview is populated a very huge data appears.
In gridview there is one column:
SR status
1425688 pending
2678549 closed
5342875 transferred
What I want to do that in a textbox user type SR number and the row containing search parameter should be selected only.l
I have a business class "Repositorio" with methods to create, update and delete objects.

The problem is that i need to select, delete and edit itens, but the grid dont recognize the other methods...
I have a gridview which contains a templatefield. Inside this is an ImageButton and a dropdownlist. This is all created in the aspx page, although the ddl list items are populated in the RowDataBound event in the vb page. When i change the selected item in the drop down list and hit the imagebutton, the selected item is not maintained after postback. Instead the first record is displayed in the dropdownlist. I have wrapped an If Not Page.IsPostback around the datasource and databind's but this doesn't help. I have tried enabling viewstate in all areas on the page too, but still nothing. The list items for the ddl must be created on RowDataBound also. As far as I am aware, my ddl is not really dynamic, its just the list items which I add in the code behind which are classed as dynamic.

The dataset is being populated, however when the page renders, the data nor the gridview are visible. I have tried using both IE and Firefox, binding / not binding the columns, AutoGenerateColumns Y / N with no success.

I am using the following :

- Oracle XE ( local )
I'm a little new in ASP.NET, so i don't know how the .NET machine fully works..I'm using two strategies to solve my problem, both invoked by a Button.Click event, but i don't know which one is better..My worries are about the server overload and page load time.This is the regular approuch i've used..

The second one is by using a funtion (named checkIfNumberExistsInDataTable) that does a binary search in a datatable to find a number
conn.Open()
Dim dr As SqlDataReader = cmd.ExecuteReader

I want to set orientation of excel pages as landscape. Is there any way to do that? Any header information to be added for file being exported to set orientation of pages as landscape?
when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.
not quite sure where I'm going wrong here. I'm trying to manually handle sorting in a Gridview that is populated with the following data source:
[Code]....

At the moment, nothing is happening when I click on the column headings. I ran it in debugging mode in Visual Studio and put a breakpoint on the Sorting event handler. I noticed that the variable dtSortTable is empty even after the TryCast(VacanciesGV.DataSource, DataTable). If I hover over this statement in debugging, it shows the data from the file system, so it does appear to be reading it.
URL...but I noticed that if move the bind from page load directly to button the code doesnt works?

We do have a search page for customers which returns a list of data from a table.
Once we select on an item it should redirect to another page with customerId as a querystring parameter..
Now the problem is we have to save all the customerIds and need to send them to display page..and need to select next one once they done with previous one without going to the search page again..
Example:
if they got 10 customers in the search page then we need to send all 10 ids to display page by starting display of firstone and once they select next button on display page they have to move on to the next cutomer from that list..if they reached the end of list they have to start again from the first...we need to avoid the user going to the search page for each customer every time...
I need the ability for a user to browse to an Excel sheet stored on his local machine and save the contents into a database table.
