Forms Data Controls :: Gridview Inline Editing Not Returning Updated Value But Prior Value?
Jun 14, 2010
I have been struggling with this and it must be somthing I am missing. I have Griview and go to edit te row and when I click update and step through the rowupating procedure the value for CollectAmtEdit and txtCollectDate give te old values. If I do not bind them originally then they return blanks after I enter data in them. Here is the form Logic:

Using a gridview with paging, sorting, inline editing, and selection enabled. I noticed the following:1. after selecting a row, then sorting, the selection sticks to the position in the grid, rather than the actual data. I would have expected it to either stick with the data, or clear the selection so nothing is selected. I would just assume clear the selection rather than have it actually change, like it is now. When a row is selected, I'm showing detail information about that specific row below the grid, so when a user does this, then sorts, the selected row changes and the new selected row's detail info shows below the grid. How should I go about stopping this? Hook into the gridview's Sorting event and set the selected row back to -1 (for nothing selected)? I assume that would work but I was compelled to post anyway to see if there is something else I should be doing...
2. I have not tested yet, but I assume the same thing would happen when paging occurs?3. another issue I'm having is when a user enters into edit mode for a row. This also does not clear a previous selection, so if a user had first selected a row, which shows the detail info for that row below the grid, then they hit the edit button for a different row, now on screen at the same time is a selected row (visible by selectedRowStyle), it's detail info below, and a completely different row in edit mode... this is a very confusing scenario for a user. I either need to ensure that any selection is cleared once in edit mode, OR sync these up so that the row in 'edit' mode also becomes the selected row... what do you guys/gals normally do for this situation? I'm thinking syncing up so that the row in edit mode is also selected sounds preferable... how would I do that?

I have a gridview control with a Delete command button bound to an Access DataSource. When a Delete button is clicked the corresponding SQL executes, deleting the data row from the database. Is there a way to cause a window to pop up allowing user to confirm the delete? Essentially, I'd like to have something like an "OnClientClick" action for each Delete button in the displayed gridview.

Is in-line editing possible on a webpart??I would like to enable a user to directly edit text within a webpart, without a postback and without launching its editor.Can someone show me how this would be done? How would I save the content using a callback?

What do you prefer? I watched a video about making a gridview and its function, and it only took about 6minutes, including the sort, delete, edit.
I don't know the difference of the two but I have made a registration form using code behind and i'm planning to make a gridview inline coding.

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 simple grid with 5 columns. The first 4 are numeric values I have formatted with templates. The last column is a total and I've added the Update button on the end. When the Update button is pressed, I have it updating the table with the new values and calculating the Total column. My goal is to have the Total column calculated after each cell is updated and not when the Update button is pressed.
I've added CommandName="myUpdateRowTotal" to
my templates.
<ItemTemplate>
<asp:TextBox ID="R01_Item_txt" CommandName="myUpdateRowTotal" runat="server" BackColor="White"
Font-Names="Arial" Font-Size="10pt" ForeColor="Blue"
Text='<%# Bind("R01_TARGET_COMMISSION", "{0:###,###,##0}") %>'
Width="75px"></asp:TextBox>
</ItemTemplate>

There is a very common problem I am facing in my new webproject in gridview control.The sequence of the execution of the process is as follows:There are some search parameters in SearchPage with a gridview. In gridview's rows there is an Edit button.By providing search parameter(s), data populated to gridview and if we click edit button a new page opens as a popup to update record.In new page the record is updated fine. On successful updation user close the window but he goes to the Search page he again finds the same record with the same parameters to see changes it remains unchanged.Its only changed when he search another record and then again provides the previous parameters.I don't know why is this behaviour of gridview?
Any idea would be helpful.

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?

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.
