I've to read Excel data from my Asp.net 3.0 VB code. My Excelsheet format is like
Company Name (Heading)
Company Address
Date:
Blank Space
Column Heading
Branch name
Data
Data
& after data
Total
Grand Total
I've to read data After branch name upto Total. Even I've to fetch data from certain columns only.
I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns()
{
// The first column to begin to insert the columns in the GridView
int columnIndex = 5;
BoundField aoColumn = new BoundField();
aoColumn.HeaderText = "New Column 1";
gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback
gvMyGrid.Columns.Add(aoColumn); // works fine
columnIndex++;
foreach (MyEntity my in _myEntityCollection)
{
BoundField myColumn = new BoundField();
myColumn.HeaderText = String.Format("{0:d}", my.StartDate);
gvMyGrid.Columns.Insert(columnIndex, myColumn);
columnIndex++;
}
}
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.
I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:

in asp.net page user able to select gridview Columns, and it will hide remaining columns and that selection done by check box with column list bellow is Image link , what exactly I am looking for [URL] it look bellow after selection of column done [URL]

View 1 RepliesI need to fetch CSV file from a webserver every few minutes.
Here's what I am planning to do:
I will create a webservice "GetCSV.asmx" which will get CSV file from that webserver.
I will create another webservice "RegularCall.asmx" which will call "GetCSV.asmx" every few minutes.
Is my approach correct? Is there a better way of doing this?
I am using ASP.NET web application and JSON webservice for this.
NOTE: There will be NO user intervention and the solution I am looking for is similar to scheduling a task on the server.
I have a dataset that has two datatables.
In the first datatable I have EmpNo,EmpName and EmpAddress
In the second datatable I have Empno,EmpJoindate, EmpSalary.
I want a result where I should show EmpName as the label and his/her details in the gridview
I populate a datalist with the first table, and have EmpNo as the datakeys.
Then I populate the gridview inside the datatable which has EmpNo,EmpJoinDate and EmpAddress.
My code is some what as below
[Code]....
Now I have a problem, I have to bind the Details of the corresponding Employee to the gridview. Whereas the above code will display all the details of all employees in the gridview.
If we use IEnumerable we give a condition where(a=>a.eno=EmpNo), and bind that list to the gridview.
How do I do this in datatable.
I modified the program as below
Igor, instead of datarelation,(my TL did not approve of it) I used IEnumerable
