VS 2010 - Blank Row In Editable Datagrid
Feb 14, 2013
I am currently working on a new data application that is a vb.net web based application using visual studio. I have a form with a datagrid view that I have customized to have all rows editable at all times. I need to get this form to show a blank row for inserting data if there is no data returned from the sql server table. I also need to get this form to prompt you to save your changes when you navigate away from the screen by any method. My asp and vb.net code is shown below.
Code:
<%@ Page Title="frmPublication" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="frmPublication.aspx.vb" Inherits="MCRN.frmPublication" %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
[Code] .....

a customer asked me for a web app, written in ASPNET, that can use an editable grid (that works with a SqlServer DB) in the similar manner as Excel works; i can use gridView with Edit link in every row but i wanted to know if there are better solutions (possibly free..) that i can use.

I don't know how to keep in sync the filtered elements of a DataGrid after the user applies a filter. The problem is when she/he tries to edit one filtered elements.... it is not the correct item!
[Code]....
How to update the index for the elements returned by the filter process?

I am in need of a very simple grid which the user should be able to edit very quickly. The grid will display a list of food items (name and price) that make up a menu.
My usual approach here is just a GridView bound to a collection of the food items with an Edit button to the left of every row. When the Edit button is clicked I navigate to an Edit page where the user can edit that item and click OK to save it to the database and then go back to the grid page, where the grid is reloaded and shows the edited item.
This approach however is much to slow, the user should be able to edit the grid much more quickly, ideally without posting back (either fully, partially or via ajax).
What I'm thinking is really simple, but I don't have the necessary javascript skill to create this...:
A UserControl that simply creates a new row of TextBoxes for every food item (along with maybe a Delete button). The 'grid' is thus always in 'edit mode' (it always shows the textboxes in every row) and the user can type in any textbox to change the name or price. When this change is made, nothing happens server side, yet. When the user presses Save, I finally run a save method that just checks all rows and saves the new values to the database.
Since the grid is so simple (just Name and Price and the underlying data has a unique Id as well obviously) I think this should be possible, but I wouldn't know how to create this...
I did try, I had a UserControl 'MenuGrid' that was nothing but a PlaceHolder (and two labels for the 'Name' and 'Price' menu headers). It has a DataSource property that I set to a collection of food items in the menu, and then for each of those food items I add a MenuGridRow (another UserControl) to the Placeholder. This MenuGridRow contains two TextBoxes and the Delete button. It also contains a HiddenField control that gets the Id of the food item.
Loading works fine, I can get all the data in this 'grid', but I don't see any way to save it back. Once I changed the items and want to Save on the server, I don't see any way to access the MenuGridRows from the MenuGrid (let alone accessing the TextBoxes on that in turn). I think the problem is that it's all just rendered to html and during runtime there is no such thing as a MenuGrid or MenuGridRow anymore. So all I have is a couple of TextBoxes with seemingly random names and there's no way for me to determine which Textbox belongs to which HiddenField (which contains the Id).
Also, I don't see any way to handle the deleting of a row; I was thinking to just run some javascript that deletes the MenuGridRow from the MenuGrid, but again same problem, there's no such thing as a MenuGridRow at that point and I'd have to figure out which TextBoxes and HiddenField belong to that row and then delete them via javascript.
I tried looking for an editable ajax enabled grid as well, so I don't have to do it all by myself, but I didn't really find anything useful. Most of the grids I found don't even work properly, some work but are still very slow (there's still a postback, they just put the grid in an UpdatePanel but that doesn't make it any faster).

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(); }

Have a gridview witha column that is read-only:
Code:
<asp:BoundField HeaderText="QTY" ReadOnly="True" DataField="qty">
<ItemStyle Width="150px" BackColor="LightGray" />
</asp:BoundField>
at the bottom of the grid I'm going to have a blank row to allow users to add a new record.
drow = dt.NewRow()
How do I make the new row column a dropdownlist?

I have a datagrid on my aspx page (it is actually a user control on an aspx page). I dont ever want this datagrid to be editable. There is an Edit and a Delete link in the last column, so if you want to edit the data that are in the row you go to a new page for that purpose.
Let's say I have four rows in the grid. If I use the Delete link to delete the third row, when the page refreshes and the grid is rebuilt, the last row contains textboxes. I do not understand why this is happening. I was not the original author of this code (disclaimer).
This is the datagrid code on the ascx page:
Code:
<!-- PRINTER GRID -->
<asp:Panel ID="ShowListPanel" runat="server" Visible="true" CssClass="aspPanel">
<asp:Button ID="AddNewPrinter" runat="server" Text="Add New" />
<h1>My Printers</h1>
<asp:DataGrid ID="PrinterList"
[Code] ....
When I bind this grid to a dataset, what would be happening to create the last row with textboxes?
Code:
Sub BuildPrinterGrid()
Dim UserID As String = SFTools.FindUserID()
Dim outputDS As New DataSet
outputDS = SQLCalls.GetPrinterList(UserID)
PrinterList.DataSource = outputDS
[Code] ....
Note that there are two procedures that handle PrinterList.ItemDataBound. Is that unusual? I don't know if this is something obvious that I just am not seeing, or something lurking underneath seemingly correct code, but I don't understand how the textboxes are getting created.

I am upgrading some code from a previous version of .NET so I converted the datagrid that was there to a gridview. I need to get the index of the row clicked. It is not working. I have an outrageous number like 577 but there's only five or so rows in the grid. Is something left over that is screwing it up?
I am clicking the View Status link:
Code:
<asp:GridView runat="server" AutoGenerateColumns="False" Width="100%" ID="gvOrderGrid" AllowSorting="true" OnSorting="SortPageCommand" OnRowCommand="ProcessItemCommand"
OnPageIndexChanged="PageCommand" AlternatingRowStyle-CssClass="alternatingItemStyle" CssClass="dataGrid" HeaderStyle-CssClass="headerStyle" RowStyle-CssClass="itemStyle"
PagerStyle-CssClass="pagerStyle" PageSize="20" PagerSettings-Visible="true" PagerSettings-Mode="Numeric" AllowPaging="true" GridLines="None">
[CODE]..
Shouldn't this line of code Dim index As Integer = Convert.ToInt32(e.CommandArgument) get me the row?

I have upgraded web application from VS.2008 to vs 2010. I was using previously ReportViewer 2008 control in a page and replaced with 2010 ReportViewer Control.
I have installed the ReportViewer Redistributable also in my local pc as well as in the server. Also as per the new requirement I have placed the Scriptmanager in the web page where the reportviewer control located.
While running the page, the reportviewer run the report and is not showing the data on the screen. It shows the blank screen. But If I export the data to execl or world it is showing the data. Also the page numbers in the reportviewer showing the total pages available in the navigation bar. I am sure the report is running and bringing the data to the screen but not showing it.

I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action.
[HttpPost]
public ActionResult Manage(ProductOptionModel DataToAdd)
{
if (!ModelState.IsValid)
{
return View(DataToAdd);
}
var ProdServ = new ProductService();
if (DataToAdd.ID != 0)
{
//Edit Mode.
DataToAdd = ProdServ.EditProductOption(DataToAdd);
ViewData["Message"] = "Option Changes Made";
}else
{
//Add
DataToAdd = ProdServ.AddProductOption(DataToAdd);
ViewData["Message"] = "New Option Added";
}
var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID};
return View(RetModel);
}
So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. I have debugged the code and checked that the RetModel variable is empty.

Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.
[URL]
I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

I have an editable html table where all rows are editable at the same time.
One column contains a dropdownlist to select an employee. I want to pass the dropdownlist's items from the controller to the view.
My View iterates through the list and displays a dropdownlist for the employee.
[Code]....
Do I have to pass a separate SelectList for each row or is it possible to share the SelectionList?
How do I set the selected value using Html.DropDownListFor() when sharing the same SelectList?

I am developing my app in asp.net web forms. The textbox is set like this
<asp:TextBox ID="txt1" runat="server" Enabled="false" ></asp:TextBox>
and this is the corresponding HTML markup
<input name="txt1" type="text" value="1.0" id="txt1" disabled="disabled" />
It is not editable upto this point.
I enable Caret browsing in IE8 (press F7) and then this field becomes editable, though the text is grayed out and consequently gives a wrong feeling to the user that the field is editable. This does not happen if I mark the textbox as readonly, but I do not want to mark it as a readonly field. how to have the textbox in disabled mode when in Caret Browsing.
Edit1: I am not looking for a solution which would change IE settings/registry, am looking for a programmatic solution as my site is a public facing website
Edit2: View states are enabled for the page and for the controls

I have a few field in my entity that i wish to be non-editable. Looking in the docs it seems like "EditableAttribute" would do the trick. However this is only 4.0Just wondering if there are other attributes that would have the desire effect. So be clear, i have a field called "DateRegistered" i wish to display this as string not text field using "Html.EditorFor"
