May 19, 2010
I have 2 pages (default and Edit). My first page is my default page which the gridview and data that is bound to the columns. I have a button column with the following asp code within the ItemTemplate:
m stuck at one place...i want to tranfer data from one database-1 to another database-2...both databases are for different web application.
Currently i am doing the same using dataset..but the problem is that when Large amount of data is coming in dataset so during the tranfer of data server gives me a Time out Error.
And another thing i am not want to utillise a server memory because there is Lacs of data into the Database for migrate.
I have a Transport Detaisl in DB , i want to dispay data on gridview with marquee scrolling up. Cabs are scheduled for drop every hour. So if drop is at 7pm i hav to dispaly on data of that hour from 6:30 to 7:15 later after 7:15 i have to display next hour data ie 8:00 pm drop data. I am able to get scrollin g data on gridview but how to schedlue it to scroll for such timings
I have a form and its code as above there are many columns and I want to do one thing that when user enter all the values in the form and upon pressing submit button all the data were show on the form..
E.g. here is the structure. I have the following fields in my form
Start Date................
End Date.................
Promo Type................
Service..........................
Submit Button
When I press submit button all of the data which i enter above was shown below.
Any method for this I don't want to use grid over here...
My requirement is need to develope a web page in asp.net using c#, which contain 4 textboxes 4 labels and 1 button and finally gridview.
Lables are:
1.StudentId (it shld be identity key and primary in db(automatic id updation))-textbox
2.StudentName-textbox
3.Course-dropdownlist box
4.Address-textbox
Note: studentId and name shld have validation.
Button:
1.Insert
REQUIREMENTS:
Gridview should hve edit and delete link button atlast. In c# pgm thr should be a sql connection when values are entered in textboxes after clicking Insert button it should insert value in gridview and also in database. If the edit button is clicked the values should display in textbox and their only we should update the values and main thing we click on edit link button the INSERT button should change to UPDATE button after updating the updated values it should save in gridview and also in database and after updating it should chance again to insert button.
The delete button shld delete the selected row in gridview.
I am new to asp.net development and I have a employee Web form that is part of a larger wesite. The webform uses a Gridview control which receives data via SQL Server tables so the web form has a SqlDataSource ID="SqlDataSource1" defined. When the page loads, the connection string automatically populates the rows of the gridview (which is a all employees).
I am attempting to create a customized sub search wherein the user can reduce the search to one person by providing either firstname or lastname, department etc within a textbox and then selecting the same from a dropdown list. Finally the user clicks the submit button (which is onclick in codebehind).
When I try to do the above I get "System.InvalidOperationException: Both DataSource and DataSourceID are defined on 'GridView1'. Remove one definition." It seems that once I define the DataSource and DataSourceID in the form, it is illegal for me to do it again in the codebehind. Is there a way to refresh the Gridview that I already have with code from a button_click. I have code attached.
I have a form that shows simple table and let the user select a row. when user select a row the record shows in a formview below the gridview. After I update the formview changes take place in database but shows in gridview ONLY the next time I load the page.
I have a gridview which has 4 columns, each holding an ImageButton in a templateField column. When I click on one of these image buttons the clicked upon image is displayed in Image1 using GridView1_RowCommand and this works fine.
However, when I click on one of the page numbers on the gridview the Image1 control resets to its original state and loses its ImageUrl.
I have a gridview that pops up when you click a link. It displays 5 columns.. if you click on the "select" link next to the record, i pass that rows values back to my form and submit the form again.. this works fine if i select a record that has all my form field values..
but if i pick a record that has some values that are empty it doesnt work.. after debugging im finding that for the fields that are blank on the screen, this is the value being passed " " which of course is not empty or null.. so my code doesnt know how to handle that.. i even tried to add .Trim() to the end of the gridview value and still getting that space being passed. How can i pass empty string instead of the for fields that dont have anything to pass?
This is my code i have for the SelectedIndexChanging event of the gridview
I have to link any selected record from my gridview to a new pop up form i.e pass the query string to a new form, using a command button. The new button will allow the user to add new information about the particular record and save it. A detailsview form would not work as the information that needs to be added is quite complex. I am using VB.
I am using gridview. I Added checkboc under itemtemplate.My page works fine. i have set my page according 508 standards. It looks for associated control id for every textbox, check box..etc.
When i check my page by 508 standards its giving form lable is missing for gridview item tamplate checkbox. i tried adding lable inside item tamplate and i set the check box id as Associated control id for the label. eventhough its not going off that error. After setting some text my errors are resolved.
but if add any text item template checkbox alignment is missing. i cann't hidden the lable. If i hidden the label it again show up Form label is missing. how can i add lable without effecting to GV item template checkbox alignment.
I would like to know how i could display data from an itemtemplate or any other form views/data-bound controls without having it render in tables? i know theres control adaptors, but is this reliable and will it work with asp.net 3.5?
just starting strongly typed data sets, I have managed to fill my data set and bind the gridview, but now I dont understand where to map the fields ? Inside the business logic layer or presentation layer.
working example to map fields with a select query and with an update .
