I currently have Gridview1 which gets it's data from a database and displays a list of people.I also have a Gridview2 which is initially blank.
I would like to add the functionality of adding/removing rows to gridview2 from gridview1.
I've added a checkbox column to gridview1 to allow users to select the records they'd like to move. I've also added two buttons >> and <<.
Does anyone have an example of how i can add/remove selected records from Gridview1 to Gridview2?
thanks in advance!
Gridview2.rows.add(Gridview1.rows[INDEXTOMOVE]);

A page has a gridview bound to a sqldatasource. I don't allow edits in the gridview. Most of it's columns are template fields with label controls. a formview control on the same page shows the data for the currently selected gridview row. Updates are made to the formview control. I want the gridview to reflect the updated data after it has been saved. A simple gv.DataBind() works but the data update can be involved in the gridview's sort, so if I call gv.DataBind() the updated row in gv may end up on some distant page of the grid. I would prefer that the gridview simply update any changed data in the already selected row.
What I've done so far is to have the sub that update the formview also change the text values of the labels on the selected gv row. That seems to work but does not persist. I see the changes in the gv cells, but as soon as I select another row in the gridview, the modified cells in the previously edited row go blank, for some reason.
What's a good way to do this?
Get the current page of the gridview (.PageIndex), do a DataBind(), then (re)set the page.
When we add a gridview we can enable selecting a row by checked enable selection on grid view proerty. But When we add DataList there is not 'enable selection' property for that.
Is any way to do this?
I want to bind a datalist with a table of my database and select a row to access row items or delete a row like gridview.
Please give me a sample codes .
Thanks alot.

I want to do something really simple, I just can't seem to find the EnableClientAddRow property, so I can set it to true. I have a standard GridView control on a web form. I want a button to appear on the web form. When the user clicks the button, an empty row is added to the GridView UI, so the user can enter data in the appropriate fields. The row will of course, have a "Save" button of some type in one of the columns.
I know this functionality must be in the GridView somewhere, I just can't find it. I did find some odd hacks that try to manually implement this. I'm not really interested in footer manipulations or binding tricks, just the standard add row method.
EDIT:
It appears the GridView does not support adding a row as a first-order operation. This appears to be a serious design flaw.
I typically add a new record to the underlying data source as a part of the "add record" button click action. I then re-bind the view in order to show the blank row.
The new record is typically a DataRow if the GridView is bound to a DataTable, or an object if the GridView is bound to a collection of a particular type. Not sure if that is what you consider a binding trick from your question, but it works well and is quite easy to implement.
Edit - more detail to describe the process:
Add the row to the data source, set the EditItemIndex to the newly added row in order for the row to enter edit mode, then bind the data source to the GridView. Your EditItemTemplate would contain a Cancel and a Save button. Cancel would re-bind the GridView to the underlying data source without the empty row and set EditItemIndex to -1, thereby removing the row from the GridView.
How to easily insert row in GridView with SqlDataSource
If you add a new row to the datasource, even if the row has empty values, and you databind the datasource to the Gridview, it should show up as an editable row just like any of the other rows.
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?
You need to set the EditIndex of the row you are editting on the gdvMyGridView_RowEditing event:
gdvMyGridView.EditIndex = e.NewEditIndex
This will display your EditItemTemplate for the relevant row.

Edit control does not work out of blue. You have to write a backend SQL query for it to implement. The query will most likely look like this.
update regions SET name=#name where ID=#ID
where name and ID are fields of the table. Make sure the ID is the primary key, otherwise update will not work and you won't get any error.
I have created a GridView whose columns are dynamically created based on my data source. I have implemented these columns by using the approach described here.Those columns display properly on the initial load. However, I need to implement commanding so that a user can edit / delete a row in the GridView.
At this point, I have implemented commanding as I would with a normal GridView. I have a TemplateField with an ItemTemplate that has LinkButton elements for edit and delete. The CommandName for each LinkButton is set to either Edit or Delete respectively.
Oddly, when a user clicks either the Edit or Delete link, the data in the GridView disappears. However, I have verified that I am in fact re-binding the data when one of these LinkButton elements is selected.
Can anyone provide some suggestions as to what the cause could be?
Thank you!
Here are good examples. You can figure out postback issue.
