Forms Data Controls :: Use All The Built - In Editing Functionality Of A GridView Without Setting A DataSource?
Jan 6, 2010
I would prefer that all middle tier methods that are used by GridViews be in the form that allows them to be used by ObjectDataSources...
<DataObjectMethod(DataObjectMethodType.Delete)> _
However, I am working on a project that I did not create. So, I was wondering if there is a way to use all the cool built-in editing functionality of a GridView without setting a DataSource? In other words, I am binding the datasource in the code behind (this works), and I have the following in my GridView...
And in the RowUpdating event (after the update button is clicked), I would like to call a stored proc to update a table and then use this kludge to get the GridView out of "edit" mode...
I was reviewing my old post about this issue with a accessdatasource and that was simple since the Select, Update and Delete were all written within the datasource.
But this page im having issues with is using SQLDataSource and pointing to Store procedures. My issue is that i have created the sqldatasource with Insert(storeprocedure), Select(actual select statement), Update(storeprocedure) and was trying to take advantage of gridviews capabilities for editing when connected to a datasource that has all those elements setup.
Here is my datasource and gridview code: The gridview row goes into edit mode, but the changes never take affect on the database.
As the subject says, i display a gridview filtered from 3 dropdownlist, wich all the items are from a local Data base, once i display this gridview i want to select a row with a button then and add, modify or delete data from it and then this new info is saved on the data base, so when i display the grid again i will see the new info. Im working on visual studio 2010, i dont use code behind, all is in asp .net.
I have a gridview, and I was trying to use SQLAdapter for the first time. I have it set up but I want the user to enter a Date in the last field of the Gridview and be able to update it. I was looking up examples, and I cannot get it to properly update. The field I want to be able to update is the "TADateUpdate" I have gotten it to show the texbox fields to edit, but I can't figure out a method to update properly.
I was looking at the default register functionality within the MVC , to learn from it. So on the register view the found the following code for the regester.aspx button;
<p> <input type="submit" value="Register" /> </p>
But i did not understand how the visual studio knows what to do when the user clicks on the register button to perform the register functionalities?
I have a Gridview that I am trying to add Paging to, however when the 2nd page is selected I get my EmptyDataText.n reviewing multiple sites and forums they have stated to send your Datatable to a Session - What am I missing here?
Im pretty new to ASP.net but am getting there slowly but surely! Its definitely growing on me.
The problem im looking at at the moment is i have a gridview displaying data from my SQL database, which works fine. I have enabled the selection option on the gridview which has placed a select link next to each row. Perfect.
What I am looking to do is be able to click the select button, and have the details from each column on that row go into variables when the page is posted back. I will then write these back to a different table in the database later on.
I see that when i click the link it is posting back the number of the row i have selected, but how do i use this to get the data from each column out of the gridview?
I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:
The gridview lives in a formview, which lives in another formview.
Inside one column is an end date. This column has a textbox which gets it's value when I choose a date from a calendar control. However, when I choose a date from the calendar control, the program crashes instead of populating the text box.
Here is the page and the selectedIndexChanged sub for the piece of work I'm trying to accomplish...
[Code]....
Gridview2 is inside formview3 inside formview1I have included the whole page below, but the problem area is gridview2[Code]....
I'm trying to edit the header row of my gridview to look like this.As you may have noticed, this is the Gmail layout and this was indeed what i intended for. I want to have on my header row some buttons that would then execute some actions to all the selected rows (very much like Gmail).
I have a Gridview where the user can edit a row when he click on "Edit" (this is called update mode i thinck?).
When the editing is done, the user clicks on "Update" and the changes are written into the database. Additionally i set a "ChangeMarker" in the database that the data record has been changed by the user.
I identify the row in the database i want to update with the SelectedDataKey in the Gridview:
[Code]....
In the first line where I dim EdittedRow i got an error: "Object reference is not set to an instance object". I dont understand this error message.
I have a databound gridview using datatable as datasource. Template fields are used to edit the row content.This cell value should get updated in the datatable on text_changed event without using gridView edit. Is it possible to overload the GridViewEditEventHandler for this purpose.
I ahve displayed a group of data in my gridvew with the edit option linkbutton template field for each row. The gridview columns consist of employee name and projectname and total hours field employee worked.
So in this when i click the edit button using the datakeynames alue for project name id and employee id ,i have to redirect the page to another page with the values in the grid for the particular employee.so that i can update the totalhours field in the redirected page.and if i press the update button in that page then the page should be redirected to the gridview page with the updated value for the particular employee and project. The page which should be redirected consist of project name dropdownlist, module field,date field and total hours field. No employee name field.
Using the gridview rowdatabound field i have postbacked the url page with the project name id but it does not displays the project in the redirected page.And employee name i have to redirect with the session value i think?
I also try setting editIndex to -1 in my sort function but that also doesn't work So when I am editing then sort event fire and edit item got change, so edit functionality is not working with sorting
I have a gridview control. I am not using any templatefields or boundfields. The data will be populated dynamically. I am using RowEditing, RowUpdating and RowCancelingEdit events. In RowEditing event, as we know all the cells in that row will become editable, i need to disable few columns(Cells) from editing.
i have a gridview connected with a sqlDatatsource that show/update records and that work fine
now what if i want to edit records quickely like in excell for example
so the left/right arrows to switch between columns up/down arrows to switch between records
i want to use this grid to edit invoice like table is the gridview suitable for this kind of use or i have to use another component (DB aware ideally)?
i have a gridview inside an edittemplate formview control in a master/detail scenario
so in the formview i have some comboboxs/datepicker/..etc corresponding to the master table
and a gridview corresponding to the detail table
in this gridview i enabled multi editing of rows like in this article[URL]
the problem is that even i change the values on the gridview , if i click the update button of the formview the "details table" changes isn't submited to the database
i am making an application using a datagridview... And I am very new to it. And I need to edit my datas in gridview using a dropdown list.
So this is the flow of the program. As the page load, my gridview will appear, with the datas from the database binded to it, so far I have done that already. Every row in the gridview has an edit hyperlink, so when I click that, I can change the values in that row using a dropdownlist, wherein, the item in my dropdown are aswell from my database.
I have a gridview which I use to edit text fields. How is it possible to start a new paragraph when entering text? I'm hoping that this can be done without using markup, as the users are not neccessarily going to be particularly computer literate.
I am trying to implement a online shopping Cart which enables editing and deletion of products. I created a datatable programatically and bind it to a Griview control. (datatable is stored in a session variable ). When clicking the edit button of the Gridview nothing happened. How can I impement editing behaviour to the gridview?
I'm using a simple search with a gridview. What is happening is when I click to edit the record, it presents me with the record fine but when I click Update in my FormView, the Gridview doesn't update. I have a feeling I'm missing something simple but I can't get totally sure so here is my code hoping someone can point the way.
