Hard to tell without seeing any code. Do you have caching ?

You went out of concept. Take some books and learn how web applications works, and how ASP.NET works. You can't show a open file dialog in a web application. You can use upload control which shows a file select dialog box.

You need to save the file first on server and redirect user to the location where you saved the file. Alternatively you can add the file to response and set the headers. Check this[^] to get an idea.

yeah i have done it with these headers.
I am able to save the csv file.
I want to convert the selected row from the gridview, which are selected on the selection of the checkbox of that particular row.
And i want to save the selected records in that CSV file which is getting saved at the specified location
I can do it by bytes of array.
But i don't know the procedure....

Hmm, you replied to your own message, which you then deleted.
I guess you're not familiar with the finer points of forum etiquette, are you?

You can add a button to download the data as a CSV and use the response object to write the right headers and data for the user to download the data.
This will create a file dialog for them to select where to save the data.

Hi,
I am populating DropDownList using Data Source, and assigning Value and binding it using following code.
ddlCustomer.DataSource = dsSeedData.Tables["Cust"];
ddlCustomer.DataTextField = dsSeedData.Tables["Cust"].Columns["CustomerName"].ColumnName.ToString();
ddlCustomer.DataValueField = dsSeedData.Tables["Cust"].Columns["Customer_ID"].ColumnName.ToString();
ddlCustomer.DataBind();
When i fetch value, it fetch first value from Dropdown, after click on Save button. After postback it reset all the value. To fetch i m using following code.
object[] param=new object[50];
param[0] = ddlCustomer.SelectedItem.Value;
What should be approach to Solve this problem.
Thanks.

Make sure you have viewstate turned on.
|
|
|
|
|
Yes, Navaneeth.
ViewState Property is True ( EnableViewState="True").
|
|
|
|
|
Try developer.net's suggestion. That might solve issue
|
|
|
|
|
Write your dropdown filling code in if(!IsPostBack){...} in page load event....
When you fail to plan, you are planning to fail.

Your code is a mess. Why you need initialize event arguments ? You are not binding the grid, you are not getting the data corresponds to the supplied id, you are not setting the data source, you are not calling DataBind().

Thanks for your rteply sir...Actually i bind the grid in properway,but i forget to paste the code for that.Sory for hurting you.Actually my problem is when we enter data highlight the current entered data.I sort out the problem.Anyway thanks for your reply.
With Warm Regards Sreejith.

Is there any way for sql server 2000 to alert my web application (asp.net 2.0) whenever some perticular filed value is updated ? can we use triggers ?
Lieut

|

Of course not. For starters, SQL Server doesn't do that, but even then, how is it going to communicate with a client who is already viewing a page ? And, if they refresh the page, then it's going to request the data from the server and update itself anyhow.

OK Great !! Thanks for saving my time  All i have to do now is to make the web application update itself on any user interaction.

Yeah - that's the way to go. It's a common misunderstanding, but there's no mechanism going from the DB to your app, only when the app initiates the request.
