I need to save the marks in database for each student...I have one drop down list..In this drop down contain 2 std 3 std 4 std, etc..if the user click 2 std ,2 std subjects are display in the grid with textbox for marks upload...If the user click 3 std, 3 std subjects are display in the grid with textbox...and also save the entered marks into database..and i need to edit the marks.
Is there any sample shows the best way to create an editable grid with textboxes, so when user clicks on the save button, the entire grid's textboxes are posted back to controller and bind to its model? I prefer not using any 3rd party grid such the one comes with MvcContrib.
I've seening quite a few posts on here regarding grids, but nothing specifically asking for a free grid component that supports editing. Has any body come across such a thing? Is there a JQuery pluggin that I could use? If not has anybody got any pointers on a good approach to writing my own (using asp.net mvc2 and/or jquery)?
a customer asked me for a web app, written in ASPNET, that can use an editable grid (that works with a SqlServer DB) in the similar manner as Excel works; i can use gridView with Edit link in every row but i wanted to know if there are better solutions (possibly free..) that i can use.
I am in need of a very simple grid which the user should be able to edit very quickly. The grid will display a list of food items (name and price) that make up a menu.
My usual approach here is just a GridView bound to a collection of the food items with an Edit button to the left of every row. When the Edit button is clicked I navigate to an Edit page where the user can edit that item and click OK to save it to the database and then go back to the grid page, where the grid is reloaded and shows the edited item.
This approach however is much to slow, the user should be able to edit the grid much more quickly, ideally without posting back (either fully, partially or via ajax).
What I'm thinking is really simple, but I don't have the necessary javascript skill to create this...:
A UserControl that simply creates a new row of TextBoxes for every food item (along with maybe a Delete button). The 'grid' is thus always in 'edit mode' (it always shows the textboxes in every row) and the user can type in any textbox to change the name or price. When this change is made, nothing happens server side, yet. When the user presses Save, I finally run a save method that just checks all rows and saves the new values to the database.
Since the grid is so simple (just Name and Price and the underlying data has a unique Id as well obviously) I think this should be possible, but I wouldn't know how to create this...
I did try, I had a UserControl 'MenuGrid' that was nothing but a PlaceHolder (and two labels for the 'Name' and 'Price' menu headers). It has a DataSource property that I set to a collection of food items in the menu, and then for each of those food items I add a MenuGridRow (another UserControl) to the Placeholder. This MenuGridRow contains two TextBoxes and the Delete button. It also contains a HiddenField control that gets the Id of the food item.
Loading works fine, I can get all the data in this 'grid', but I don't see any way to save it back. Once I changed the items and want to Save on the server, I don't see any way to access the MenuGridRows from the MenuGrid (let alone accessing the TextBoxes on that in turn). I think the problem is that it's all just rendered to html and during runtime there is no such thing as a MenuGrid or MenuGridRow anymore. So all I have is a couple of TextBoxes with seemingly random names and there's no way for me to determine which Textbox belongs to which HiddenField (which contains the Id).
Also, I don't see any way to handle the deleting of a row; I was thinking to just run some javascript that deletes the MenuGridRow from the MenuGrid, but again same problem, there's no such thing as a MenuGridRow at that point and I'd have to figure out which TextBoxes and HiddenField belong to that row and then delete them via javascript.
I tried looking for an editable ajax enabled grid as well, so I don't have to do it all by myself, but I didn't really find anything useful. Most of the grids I found don't even work properly, some work but are still very slow (there's still a postback, they just put the grid in an UpdatePanel but that doesn't make it any faster).
I have a page with one dropdownlist and one grid. when dropdownlist's selected index is changed i generate a BindingList with some data based on the dropdownlist's selected value. this BindingList is binded to the GridView with one readonly column (eg: Item) and one column for entering data (eg: qty).
i need the Qty column to directly editable (without pressing edit, then goes to edit mode). and update this values back to BindingList's corresponding Item when the qty cell's focus is changed.
I am using Gridview and on that data is binded conditionally.the problem is that at the time of editing whole row of the grid is in editable mode and i want only few of the columns editable. my code is as follows
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 am trying to upload a text file and display the content in a grid view. However, when i try to upload it,it appear this error? Oh ya, do you know the code to upload text file? If you know can u edit my code to make it take the file from fileupload instead of textbox?
The error is:
Index was outside the bounds of the array. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.IndexOutOfRangeException: Index was outside the bounds of the array.
I'm having problem getting the syntax right for an SQL statement for a Progress database. I have the column "Resource" which is a reserved word and according to the Openedge SQL Reference I can only use reserved words if I delimit them with double quotation marks.
So how do I write this line...
Dim comm As New OdbcCommand("SELECT Resource FROM PUB.ActOper WHERE CreDate > TO_DATE ('05/24/2010')", conn)
...with double quotes around Resource? I've tried a bunch of different combinations but I get "Expression expected" or "valid continuation expected" or something similar.
I develop one concept, i want to query how to compare marks/reports all student in a class, compare subjects, previous marks/reports. another concept in my page i display charts in this charts i put a dropdownlist in this ddl pie, line, bar charts are their but i selected any one that chart type visible
I'm running into a really weird issue: when a user copies text from another file and pastes into an ASP textbox, question marks occasionally appear. For example, copying text from one file ("P/U FILE5") pastes correctly into the ASP textbox, displaying as "P/U FILE5"
However, in the database, the text is stored as "P?/?U FILE?5"
So by way of checking and converting the textbox string to a byte array, I see byte values like this: "80 63 47 63 85 70 73 76 69 83 63 53" which means that when I actually look at the VALUE of the textbox string, it's actually sticking question marks in there. But they don't appear anywhere in the textbox!
<div id="mydiv">This is a "div" with quotation marks</div>
I want to use regular expressions to return the following:
<div id='mydiv'>This is a "div" with quotation marks</div>
Notice how the id attribute in the div is now surrounded by apostrophes?
How can I do this with a regular expression?
Edit: I'm not looking for a magic bullet to handle every edge case in every situation. We should all be weary of using regex to parse HTML but, in this particular case and for my particular need, regex IS the solution.
Edit #2: Jens Ameskamp helped to find a solution for me but anyone randomly coming to this page should think long and very hard about using this solution. In my case it works because I am very confident of the type of strings that I'll be dealing with. I know the dangers and the risks and make sure you do to. If you're not sure if you know then it probably indicates that you don't know and shouldn't use this method.
As i am trying to do crystal report task as it is aim is to calculate the Sum Of Subjects Marks And calculate the percentage ....I am not able to calculate the percentage.
have a web based application (ASP.NET 2.0) on a virtual dedicated Windows Server 2003 SP2 box, that converts HTML forms and converts them to PDF using ABCpdf. It has been around for years, and hasn't been changed for at least the last two of those years.Three days ago it started placing question marks throughout the outputed PDF documents
