Forms Data Controls :: Editable Multiple Nested Gridview
Aug 19, 2010
I've got this page where I display a 3 level nested gridview. First gridview displays data, 2nd one displays data based on the 1st one's row and 3rd one displays data based on the 2nd gridview. All of this works perfectly, including the edit mode for the 3rd gridview.
The issue comes when I make each gridview collapsible, again, it works fine but when I click on "Edit" on the 3rd gridview all the grids collapse, I can then re-open them and the "edit mode" is still present and I can still save my updated data. But that collapsing thing is quite annoying. I based a lot of my code from this page: [URL] And I understand how I can fix my issue on a 2 level nested gridview, by simply adding the C# code:
[Code]....
This makes allows me to save the index and prevent it from collapsing when I'm editing. Unfortunately, because I'm actually editing the 3rd gridview, if I code:
[Code]....
That simply doesn't work because I get the error "GridView2 does not exist in the current context". I also tried adding it to the .designer.cs page, but that doesn't change anything and still doesn't work. I'm not at work atm, and hence cannot paste the entire code, however, would anyone still have any idea as to how I can fix that issue?

I found the article about Nested GridView Example in ASP.Net using C# and VB.Net
I tried it with a third level, but have problems of binding data. How it could work?
<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="false" CssClass="Grid"
DataKeyNames="t1000_customer_id" OnRowDataBound="OnRowDataBound">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<img alt="" style="cursor: pointer" src="./images/plus.png" />
<asp:Panel ID="pnlOrders" runat="server" Style="display: none">

I am trying to write an app that has one gridview, but I change the select on my sql data source to show different information on the same grid. For example I start showing units, but when price is selected I reassign my select command from Select sales.[sales1] to Select (sales.[price] * sales.[sales1]) as sales1.
However, this is causing a problem that I cannot understand with the built-in edit functionality of gridview. Whenever I click on edit, all the data in my gridview reverts back to the original select and displays only units. Am I missing something? When I change my select command the only things I am changing are my gridview.datakeynames, sqlsource.selectcommand, and sqlsource.updatecommand. What do I need to add to make my gridview edit using the current selectcommand?

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

Note: Code is taken from this tutorial [URL] I currently have an editable gridview with only some columns editable by the user. In the background I want to record the time/date they have saved the data to the grid. This column 'Time' is not bound to the grid. Is there anyway I can still include this update when rebinding the newly edited data?
I'm also having a problem saving the updated data of my column ActivityTotal. I've been debugging that and following the variable, and it holds the correct value, but just doesnt seem to update. I am providing the codes below for both my gridview and the cs behind and would be grateful if someone could take a look, I assume it's a sort of minor sql issue on my part.
code
protected void UpdateButton_Click(object sender, EventArgs e) { originalDataTable = (DataTable)ViewState["originalValuesDataTable"]; foreach (GridViewRow r in GridView_ABC.Rows) if (IsRowModified(r)) { GridView_ABC.UpdateRow(r.RowIndex, false); } // Rebind the Grid to repopulate the original values table. tableCopied = false; GridView_ABC.DataBind(); }

Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

I'm creating a gridview that should always have a row on the top of the gridview irrespective of whether there exists data to bind to or not. This row should have a column with a textbox to insert data.I tried creating a header template and setting showheader to true,but it won't display.
<asp:GridView ID="gvwMessages" runat="server" AutoGenerateColumns="false" ShowHeader="true"> <Columns>
<asp:TemplateField HeaderText="FileNote">
<ItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" />
</ItemTemplate>
<HeaderTemplate>
<asp:CheckBox ID="CheckBox3" runat="server" />
</HeaderTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Date">
<ItemTemplate>
<asp:Label ID="Label7" runat="server" Text="Label"></asp:Label>
</ItemTemplate>
<HeaderTemplate>
<asp:Label ID="Label8" runat="server" Text="Label"></asp:Label>
</HeaderTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Created By">
<ItemTemplate> <asp:Label ID="Label9" runat="server" Text="Label"></asp:Label> </ItemTemplate>
<HeaderTemplate>
<asp:Label ID="Label10" runat="server" Text="Label"></asp:Label>
</HeaderTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Message Lines">
<ItemTemplate> <asp:TextBox ID="TextBox2" runat="server" TextMode="MultiLine" Enabled="false"></asp:TextBox> </ItemTemplate>
<HeaderTemplate>
<asp:TextBox ID="txtHeaderMessage" runat="server" TextMode="MultiLine"></asp:TextBox> </HeaderTemplate> </asp:TemplateField>
</Columns>
</asp:GridView>

In Nested Grid, we get a '+' sign. The problem is that '+' sign appears all times, even if there are no child records for that row. 1. Can we enable/disable OR Hide/Unhide '+' sign. depending on if child rows exits.2. OR alteast we can put some bgcolor indicating to user that this record do have child rows. Without any indicator user may feel quite annoying to click on '+' sign and nothing happens.

I have a gridview which enables editing. The editing sequence works fine. When the user clicks the edit button, I want ONLY the row to be edited to be shown, and all others to be hidden.
This is the code that I have, but it isn't working. Can anyone tell me why and how I can fix it? I am using a dataset to bring text from an XML file.

Sorry if I suffering from morning-brain, but I can't find an answer to this, right now, but it seems such a beginner's question. Is there a way to make a gridview "fully editable"? By this, I mean that rather than the normal gridview edit method, where you have to click a row to edit it and then click to update the dataset, you can set certain columns (and also, only certain rows within those columns) to be editable all at once?

I need to display 144 records in some form of Grid/Spreadsheet view. Currently I have the records being displayed in a Gridview, however this means that if the user needs to make multiple changes to the data that is being displayed then they would have to hit the edit and then update for each row. What I would like to be able to do is have them Edit whatever rows and columns they need to and then have them click update once. Is this possible, if yes then how?

I have a gridview with bound fields and a templateField that receives data from a submit button which, depending upon the selected object, i.e. dropdown 1, 2, or 3, return a result set. The gridview also has a checkbox column which is used as a marker to determinie the rows to be added to and existing table. If a user selects multiple row, those rows are written to the database. Everything works.
Now, I need to add additional functionality to the gridview:
Upon selecting the checkbox, programmatically the accompanying row must become editable; for each row presented.
Deselected the checkbox, return the gridview row to a read-only state.
There are 14 columns, one of which is a dropdown which needs to maintain its default value.

I am looking for a way in which to make a column in a GridView editable.
Currently i am looking into overriding the GridView so that the whole view is editable and then making all the column I do not want to be editable, read only.
I'm sure there is a better way, but I cant find it.

I have two pages; one page similar to a 'dashboard' displaying an incoming correspondence gridview and the other page 'incoming' displaying the same gridview of incoming correspondence. So my dashboard page is just a snap shot of what some pages have. So there are main pages that are being summarized in the dashboard. What I want to do with the Incoming gridview in the 'Dashboard' Page is once a user clicks a row in that gridview it obtains the correspondence id and redirects to the Incoming page and make that row in that gridview(same view or query as the gridview in the dashboard) editable.
What I have right now is I am obtaining the correspondence id for the row selected and redirecting to the Incoming page but have noo idea how to make that row editable in the gridview in the Incoming page.

Solved like this
currentID = Convert.ToInt32(GridView_ABC.DataKeys[0].Values[0]);
activityName = Convert.ToString(GridView_ABC.DataKeys[1].Values[1]);
DataRow row =
originalDataTable.Select(String.Format("EmployeeID = {0} AND ActivityName = '{1}'", currentID, activityName))[0];

I've got my data in the gridview via:
[Code]....
Now I need to make all the data editable (add, update, delete). Why isn't the Gridview the same as DataGridView? With the DGV, the data showed EXACTLY as it did in the database and one could add a record, edit a record, or delete a record.
