Editing A Row In A Gridview?
Mar 23, 2010
I have a two text boxes named region id and region name..and a button control
I enter some values into those text boxes and click the button to insert those values into the "gridview"and a "data table" associated with the gridview.
The gridview has the "enable editing" set to true..but when i click the "edit" button of a particular row in a gridview i get no response...i.e i do not get editable textboxes as it happens normally...
What is the solution for this?

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:

I've got a GridView that can be edited. My problem is that when I click Edit, the textbox is too small (the File Name column). It isn't large enough to display its contents, and it isn't as wide as the rest of the column.
How can I make that textbox wider?
Here's the ASP code:
<asp:GridView ID="FileGridView" runat="server" AllowPaging="True" OnPageIndexChanging="FileGridView_PageIndexChanging"
CellPadding="1" CssClass="GridView" GridLines="Horizontal"
Width="100%" AutoGenerateColumns="false"
AutoGenerateEditButton="true"
OnRowCancelingEdit="GridView_RowCancelingEdit" OnRowEditing="GridView_RowEditing" OnRowUpdating="GridView_RowUpdating"
>
<Columns>
<asp:BoundField DataField="Name" HeaderText="File Name" />
<asp:BoundField DataField="Length" HeaderText="Size" ReadOnly="true" />
<asp:BoundField DataField="LastWriteTime" HeaderText="Last Modified" ReadOnly="true" />
</Columns>
<RowStyle CssClass="GridViewRow" />
<EditRowStyle ForeColor="Black" CssClass="GridViewEditRow" />
<SelectedRowStyle Font-Bold="True" CssClass="GridViewSelectedRow" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<HeaderStyle CssClass="GridViewHeader" ForeColor="White" />
<AlternatingRowStyle CssClass="GridViewAlternatingRow" />
</asp:GridView>
There's C# code behind this to update the data, and that works just fine. I hope the solution to this is in the ASP, but if the solution requires some C# code.

I am looking for some examples for gridview for common tasks like displaying, editing, deleting, paging, sorting, batch updates etc, but WITHOUT using any datasource controls. I would like to bind the data in the code to custom object collection. all the samples I found on the web so far use some data source control, I think Enterprise applications shouldn't be using this pattern. objects in my solution have only business logic and no data access code. instead I use manager objects to do this. if you have any examples of gridview that performs the common tasks without using any data source control.

I'm having some trouble with editing a gridview row's background color when Editing it.
The thing is, I am using the RowDataBound event method to change e.Row.BackColor based on a criteria when displaying the report( 3 different colors depending on result ). For the rows that don't fall under that criteria, a GridView's property <EditRowStyle BackColor="#999999" /> is applied upon clicking the Edit button.
However, I can't seem to find a way to change the color of those that do fall under the criteria since RowDataBound seems to be called all the time, overriding any changes I make.

I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries

I have a gridview which has editable columns.
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...

I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database.

Well the dropdownlist has an existing items. I just want the selected gridview record to be displayed in the dropdownlist. The dropdownlist has several DataTextField in string and consist of DataValueField in numeric. The gridview passes a string text to the box which has an equal or same item inside the dropdownlist. Whenever i passed a record from a gridview to be viewed in the dropdownlist it just duplicates the same item. Q: How can i simply pass a text inside the dropdown and just simply display it without adding on the list.
sample item on the dropdown:
--Select--
Account
Savings
after selecting on the gridview and display inside the dropdown:
Account
Account
Savings
(you see the '--Select--' was erase and replace with the selected record)

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 finally got membership and roles setup and seems to be working. I have setup a page to allow the creation of a user and editing of roles for a user. I would like to setup a page with a gridview that displays all users and what roles they are assigned. I remember running across someone else that was looking to do the same thing, but cant find it. Not sure if it was in this forum or online somewhere else.
But i found that i can use the aspnet_Membership_GetAllUsers procedure in my db to get all the users, but how can i add the roles to each person and possibly setup the gridview so that each role they have, is displayed on their row in the gridview So i would like to see something like this maybe more data displayed depending on the client request.
Username Email Last Login Roles
meofcourse me@hi.com 08/25/2010 X Admins X Approvers
themofcourse them@hi.com 05/25/2009 X Approvers
The X indicating a checkbox.. and have it setup so they can uncheck the role, that triggers the update and causes the list to refresh and display the new current roles for the individual users. The procedure listed about does not return the roles, so wasnt sure if i could use that procedure and union it with another to get the combined results im looking for.

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:

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 setup a gridview within an update panel, which resides in a tabcontainer. After I edit any of the rows within the gridview and hit "update" the page reloads and I am no longer able to edit any of the text boxes in the other tabs, and if I attempt to insert or edit a row within the same gridview I'm not able to edit those either. That said, when I hit the tab key a couple of times the cursor appears and I'm able to proceed with editing. Based on the number of times I hit the tab button, it appears that the cursor was inside the textbox I clicked, though it wasn't visible and I simply wasn't able to enter any text.
I've been trying to setFocus on a specific field after any of the grid updates, also tried setting the cursor using ScriptManager.GetCurrent(Me).SetFocus(Me.Control) with no luck.

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?
