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)?

View 1 RepliesIs 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.

View 1 Repliesa 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.
View 1 RepliesI 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 created an application which shows records from the database i have to make my grid view editable so that it will reflect into the data base
View 17 RepliesI 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

I want to create a reusable user control which contains a date time picker in asp.net. Need to add this user control in a grid view as column.While clicking the column,date time picker has to be displayed.Which is the suitable method,Creating the component or creating the user control. Also want to know, How to add this component in to the toolbox?
View 2 RepliesNote: 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 stop the data flow when certain conditions happen in the script component. Like if a row in the data set has an invalid date, I dont want that dataset to be inserted in the tables or go through OLEDB Destination, rather I want the entire data flow for that dataset to stop and go back to the control flow page.
I have tried mulitple solutions but nothing worked. Conditional Split ends up inserting the correct rows, but I just dont want anyting to be inserted when one row is bad, where as I do want the entire dataset to be inserted if all rows are good.
How can I fail the component when certain conditions happen int eh script component.
I would like to know how can I list for every page (child page) selected the number and id of localize component in the current page. I need this to update resources files, a button will be on the master page and when they click on it, they will go to a page which show up every data in the resource file.

My View iterates through the list and displays a dropdownlist for the employee.

How do I set the selected value using Html.DropDownListFor() when sharing the same SelectList?
