I am working with Gridview control and I am also adding radio button to each row in ASP .NET.
Here is something that I would like to accomplish but I am not sure how this should done. The problem is that I have add a muliple datarow insie of the each gridview. Something like below.
So, some cases I have add a row with two rows like the example. And, the ID eventurally will be radio button where user can click.
I follow this code [URL] it works. But the example is show only for 1 row.. come to my case when user want 12 rows for the first time gridview row load. I manage to add it by using for loop. but i stuck at the how to set previous data when user add new row to 13th row. The gridview seems like refresh and the entered data is gone!
View 1 RepliesI'm having difficulty adding a repeating header row, every x rows, to a gridview. I'm able to add the header only once with the below code. For some reason it will only add it during the last iteration through the for/next statement. I tried manually adding three separate .addat statements to different rows and it only executed the last .addat statement. I couldn't find any information on why it's only working the one time and I hope someone has a fix or better solution.
Code snippet (Note the IsWhole() function verifies that the rownumber divided into a whole number):
Protected Sub Gridview1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Gridview.DataBound
Dim grid As GridView = TryCast(sender, GridView)
If grid IsNot Nothing Then
Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal)
Dim header As GridViewRow = POSTURE_RESULT.HeaderRow
For i As Integer = 0 To POSTURE_RESULT.Columns.Count - 1
Dim TableCell As New TableHeaderCell()
TableCell.Text = header.Cells(i).Text
row.Cells.Add(TableCell)
Next
Dim t As Table = TryCast(grid.Controls(0), Table)
If t IsNot Nothing Then
For i As Integer = 0 To Gridview1.Rows.Count - 1
If IsWhole(i / 5) Then
t.Rows.AddAt(i, row)
End If
Next
End If
End If
End Sub
I need to produce a from where I can add multiple parts. Each time a user enters a part number, the description should be populated. The user can then click add and this part and description will be shown below. They have the option to add as many parts as they require. Once all parts are added the user fills in some general info eg description and then once a submit button is clicked all part info will be inserted into a table and general info will be inserted into another table with one unique ID.
View 5 RepliesI am accessing rows in an SQL database table based upon the contents of 2 Primary key columns. But, I cannot insert new rows in the table when the content in one of the new Primary key columns already exists in another row. I get an error message that says: "Violation of PRIMARY KEY constraint 'PK_ReferendumVoters'. Cannot insert duplicate key in object 'dbo.ReferendumVoters'. The statement has been terminated."
The reason why this error is occurring is because I first stored "Referendum 1" in one column along with "me" in the second column of a new row for a "ReferendumVoters" table. Then, I attempted to insert a new row with the same "Referendum 1" string in the first column along with a different name in the second column. But, it will not let me do this even though I created a new index that defines the two columns as unique. Is there any way that will enable me to do this?

View 1 RepliesI have a gridview with empty data template. In this empty data template i have a table(HTML) with 4 columns. When user enters data i want to save this in a datatable temporarily at a button click event.. Again if user wants to add one more rows data that also should be added to the same table where i added previous row data. So now the datatable has 2 rows. Like this he may add any no of rows. What i want is all the rows should be displayed when i bind datatable to gridview..At the click event i am adding 1 row at a time to the datatable
View 1 RepliesI am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
I have a gridview that I bind on Page Load event.In the rowdatabound event I want to add a row to the gridview and bind it based on the value of the current record.The row is not being added. Is there a way to bind the extra row in the rowdatabound event?

How do I add maximum rows that can be added ?
I have the need to allow a user to "tab through" making edits on a gridview. There will be one editable column in the row data. The user should be able to hit tab and go to the next row to edit said column. I have not found any easy method to accomplish this task. I found a way to programmatically put a gridview into edit mode, but in testing the code below it works for only 1 row at a time.
reviewTransferGV.EditIndex = 0;
reviewTransferGV.Rows[0].RowState = DataControlRowState.Edit;
reviewTransferGV.EditIndex = 1;
reviewTransferGV.Rows[1].RowState = DataControlRowState.Edit;
reviewTransferGV.DataBind();

Sql select statement returns: customer_name, month, and count. There is one row per month as follows:
name-1, 01, count1
name-1, 02, count2
name-1, 03, count3
name-2, 01, count4
etc
I want to be able to display as follows:
Customer----Jan-------Feb-------Mar
Name-1______count1____count2____count3
Name-2______count4
etc.
There will be some customer that don't have a month record. The display can show all 12 months.
My questions are: 1) Is datalist or gridview the best? 2) Where can I find examples of how to do this? 3) Also, an example of "no data" for a month. I'm a beginner, have been trying to research, but can't seem to get headed in the right direction.
I am trying to populate the values of multiple rows in single row in gridview using c sharp in rowdatabound section of code behind page like:

Col1 Col6
a 1

Now I want to achieve this?

What wrong with the code below?
if (e.Row.Cells[0].Text == "" && e.Row.Cells[5].Text != "")
{
for (int a = 0; a<GridView1.Rows.Count; a++)
{
string s = GridView1.Rows[a].Cells[5].Text;
GridView1.Rows[e.Row.RowIndex - 1].Cells[5].Text += s;
}
}
What mistake I am making?
Cell[0] is Col1
Cell[5] is Col6
