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 am working on a report using local mode ReportViewer. The report layout is 2-column newspaper style. When I run the report, only one column is filled in on the first page but both columns are filled in correctly on subsequent pages.

I tried to include two columns FirstName and LastName as below but didn't work.

I have a web form for handling invoices which has a form view. When I'm in insert item template, I need to have various fields. Some of them are contract number, invoice number, register date and other that are easy to handle. But there is a dropdown list related with a table of prices (the table has price name, price initial payment, number of payments, amount of month fee and so on). So, when the dropdown is selected, fields related with price should get their values from price table, and then the user decides to keep them or type in new values. How can I get it done? Should I use a Dynamic populate extender or type all the code behind using SelectedIndexChanged method to populate price related controls?

I have a gridview containing 10 columns. Three of them are set to visible="false' by default. When I click on 'Export to excel' Button, I can hide those invisible columns.

There must be more efficient way than this. How can I find the invisible columns and store their information in array and then only do a loop once?
I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

View 1 RepliesI am trying to export my Model to an Excel sheet. I have 31 fields out of which only 29 are exported. Among the 3 fields that I am not able to export 2 are of type Enum and one of DateTime. Their is another DateTime field also, but that is exported properly. Here are few fields of the model :
[EnumDataType(typeof(Suffix)), Display(Name = "Suffix *")]
[Required(ErrorMessage = "Suffix is Required")]
public Suffix NameSuffix { get; set; }
[EnumDataType(typeof(InquiryStatus)), Display(Name = "Status")]
[Required(ErrorMessage = "Status is Required")]
[Code] ....
Among the 4 fields above, NameSuffix, Inquiry_Status & FollowUpDate are not exported. InquiryDate is exported.
My exporting code is :
DataGrid dg = new DataGrid();
dg.DataSource = inqs.ToList<Inquiry>();
dg.DataBind();
string filename = "InquiryList_" + DateTime.Now + ".xls";
Response.ClearContent();
[Code] ....
In the ContentType, I alos tried with ""application/ms-excel";, but that makes no difference.
What can be the error for the above ?
I am trying to insert 8 different selected values from a CheckBoxList into 8 different columns of a database. As it now, I am only able to concatenate all 8 selections into a single string in one column. But this is not what I want to do. In my DB I have Column1, 2, 3, 4, 5, 6, 7, 8. Is there any way of getting this done?
View 5 RepliesI'm trying to find a code to delete multiple columns because when you delete a column the next column takes his place so for example:
If you delete column 6 then column 7 becomes column six.
I tried the following code with an for loop & a while loop:
Dim field As DataControlField = gv.Columns(i)
gv.Columns.Remove(field)
&
gv.columns.removeat(i)
But same case that the column 7 becomes column 6
The variable removeColumns is an array with the column number that need to be deleted.
If wanted I can also provide the Header Names

This is a question for who works with both PHP and ASP.NET/C#/VB.I plan on learning both languages over time, but I am curious in the order you learned both technologies? And Why?Maybe you just chose by time/ease to become good in the language or you just prefer one language over the other.I want to learn both technologies so, if for some reason my projects don't workout, I have a backup plan as a web developer for clients. I would really like to service both sides of the isle, Windows and LAMP
View 10 RepliesI have a page within our site that allows admin users the ability to upload configuration settings into the system instead of submitting 1 at a time.
While testing yesterday, i found that one of the upload pages allowed me to upload a excel file that had alot more columns than expected and when i checked the database, the first few columns that were expected took the values from the file, and everything else was ignored, but wanted to see if there is any way to check the number of columns in the file to make sure it matches the upload logic before accepting it.
