View 2 Repliesi need to show 3 gridviews in a tab container (ajax).. which should refresh at same time.. what is the optimal way to get data from database for that can some one show a solution for this .
i need to design an application in asp.net using gridview custom control. the gridview will show hundreds of records using paging with checkboxes in every row. if the user checks 3 rows in first page of gridview which is showing 9 rows, those 3 rows should appear on top in the next gridview page and the page should display only 6 new records. ie 6+3=9 similarly if user checks 2 more rows, the next page should show 3+2 rows(from first 2 pages) on top and only 4 new rows ( 3+2+4=9)software developer
why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
View 3 RepliesI have this code that hides a column in a gridview. (The column houses another nested gridview).
[Code]....
The trouble is that if I click the select link on one row that action to hide is carried out on all rows. How can I set this up so that it only hides the row that is selected?
Note: Code is taken from this tutorial [URL] I currently have an editable gridview with only some columns editable by the user. In the background I want to record the time/date they have saved the data to the grid. This column 'Time' is not bound to the grid. Is there anyway I can still include this update when rebinding the newly edited data?
I'm also having a problem saving the updated data of my column ActivityTotal. I've been debugging that and following the variable, and it holds the correct value, but just doesnt seem to update. I am providing the codes below for both my gridview and the cs behind and would be grateful if someone could take a look, I assume it's a sort of minor sql issue on my part.
code
protected void UpdateButton_Click(object sender, EventArgs e) { originalDataTable = (DataTable)ViewState["originalValuesDataTable"]; foreach (GridViewRow r in GridView_ABC.Rows) if (IsRowModified(r)) { GridView_ABC.UpdateRow(r.RowIndex, false); } // Rebind the Grid to repopulate the original values table. tableCopied = false; GridView_ABC.DataBind(); }
I have a table in my Database called Creditors.
One of the columns is Paid which is type Bool.
On my aspx I have an objectdatasource and gridview. In the DAL is a method called GetCreditors which
returns all the creditors into the Gridview.
In some cases the "paid" column is ticked and in other not.
I want to run a select query that only gets the rows where PAID is not Ticked. insead
of retrieving all.
How do I loop the gridview to read or insert one row by one row?I have a database which has a Primary key. Currently,all the rows seems to appear at one time.Even when I use a counter,it did read one row from a textbox(which is for my testing to read one row) but in the database,it still inserts the whole rows from the gridview.I can't click button twice as it will occur an error "Primary Constraint".
View 6 RepliesI have the following fields in an Appointment table:
ID(PK), TeacherID, DayID, TimeslotID, ParentID, StudentID, Remarks & Editable(bit, Default value=1)
I am developing an application to allow parents to book appointments to meet the child's teachers.
It is compulsory for parents to meet child's mentors, hence Appointments to meet class mentors are already pre-booked in the Appointments table.
Parents could still book appointments to meet other subject teachers. I have a column in my gridview to show parents the list of booked appointments. Parents are allowed to change the Appointment timeslot for an appointment they booked and are not allowed to change appointment time for pre-booked appointments.
Under the Remarks colum, it is stated that the following appointment is pre-booked by class mentor.
How do I make only those pre-booked rows read only since all the appointments belonging to a parent is under one GridView.
I found an example, but this is to only make the 1st 3 rows read-only and I don't think this is in VB coding. I'm usingASP.NET VB coding.

It runs very well until i use the Gridview paging.

The grid view row command does not execute on my production environment. This is a intermittant issue. I am not able to reproduct the exact steps but it does occur too often.
I have a load balanced environment with 2 identical servers in the farm. The servers are running on IIS 7.5
The other scenario in which I observe this is when the session times out. In that case the grid view events are lost. But this scenario is not a priority for me. I need to resolve the first scenario.
Any help on this or some useful links on "Understanding the session" or "understanding the complete event firing and execution" is welcome.

View 2 Repliesi'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource();
sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString();
sq.SelectCommandType = SqlDataSourceCommandType.Text;
sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1";
string result = sq.Select(some overload that's stopping me);
How to update a colums value of a Row in a gridview on Row Command Event Handler. I am using a SQL Datasource.
[Code]....
I have made Gridview and it has 5 columns.
Col1 Col 2 Col3 Col4 Col5
I try to make like below:
Col1 Col2
col2 col3 col4 col5
First column is as it is. But next 4 columns I try to make merge from Gridview Row Databound Event. It's working.
I have a link button in column1 and when I click on it, Row Command is fire and at that time the merge is gone. And Last row comes in footer row.
I'm creating a confirm delete like popup with an iframe to use along with a gridview. When you click delete on a gridview row, the iframe shows up and asks if you would like to delete the associated image as well from the server. It works perfectly the first time I delete a row. After that whenever I click select or edit on a new row, it calls the rowdeleting event from the last deleted entry every time. I'm stumped.Here's the Sub:
'// Event that Occurs when the Delete Button is Clicked //'
Protected Sub Confirm_Delete(ByVal sender As Object, ByVal e As GridViewDeleteEventArgs) Handles GridView1.RowDeleting
Dim file_name As Array = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "/")
If file_name.getLength(0) = 1 Then
file_name = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "")
End If
Dim fn As String = file_name(file_name.getLength(0) -1)
fn = replace(fn, ",", "%2C")
fn = replace(fn, " ", "%20")
Dim url As String = Me.Master.get_root_url & "CrimeBulletinProject/ConfirmDelete.asp?img_list=" & fn & "~!"
confirm_delete_frame.Attributes.Add("src", url)
confirm_delete_frame.Attributes.Add("style", "display: block; left: 50%")
End Sub

Working in Asp.net 4.5 + Kentico CMS
I have Repeater in usercontrol and Inside the repeater i have 1 itemtemplate in which i have ImageButton on it. Also i am handling the Click event on the Imagebutton using ItemCommand of the Repeater. when i click the image button it fires the item_command on the codebehind which is fine. But if i use !Ispostback on page load to stop loadinghte databind event again which is in pageload, it's not firing the Item_Command Event.
If i remove the !Ispostback from my page it's doing the pageload event againt which has calling my databind method and then it calls the Item_commands event. Wondering is this kentico issue or usercontrol problem?
so I know that DataTables are often used as the DataSources for gridviews. Lately, I have found that I can also use generic lists as data sources for gridviews. But I figured that out by simply trying it to see if it worked.
I have looked all over the web and simply cannot find any kind of inclusive list or description of exactly which data structures can be used as the data source for a gridview. Does anyone know if there is such a list, or some kind of reference that I can look to for this info?
Although it sounds like an obvious question, like there is obviously one out there and I just haven't looked, my experience has been that it's just not so.
