Forms Data Controls :: Editing A Row In Gridview By Postback To Another Page?
Feb 7, 2011
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 have a GridView in an update panel that is bound (in code-behind) to a business layer object. The first time this page is accessed, Editing, Deleting, Updating, etc. work fine. However, if I click my browser's refresh button, the functionality of the edit, delete, etc link buttons is gone. They do nothing.
here's my code:

I have a gridview pulling all data from one user. This gridview has an edit button and when that is clicked the gridview becomes too wide for the div/screen and I get a scroll bar. Since this gridview can only have one user in it anyway is it possible to display each field on seperate lines instead?

I design a page which contains one dropdownlist, gridview1 and gridview2. All of them extract data from the same table (a SqlDataSource). The Gridview1 is used to edit, update data with edit, update and cancel button. My problems are:
1. After update gridview1, the dropdownlist and gridview2 don't update data.
2.After updata gridview1, the gridview1 resets to its original state if refresh page.

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 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'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 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 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 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.

I have a gridview with a edit button for each row. Selecting an edit button changes the row to Edit mode. When in Edit mode, the row ID's are not being captured correctly. Any row I select defaults to one of the first 2 rows I had selected earlier.If I first select Row 1, it puts that in edit mode. When I "Cancel" out of it, row 2 goes into Edit mode. Now, when I select row 3, row 1 goes into edit mode again. From this point, any row I select puts either row 1 or 2 into select mode.
