to manually (via code) add a row to a GridView and then set it in edit mode immediately? I know how to set a row in edit mode via simply doing the following:
[Code]....
The GridView is currently binded to a generic list.
how to place a row in the edit mode in gridview on button click. have tried the :
GridView1.EditIndex = 0;
has the issue that the button has to be clicked twice to the row to become editable.
then in this way the old update and cancel will not appear.
I am interested in ADO.NET method.
I have several places where I have a gridview and dataview set, and when I hit an edit button on the gridview it opens up the dataview. When I hit a cancel button fom the dataview I have this code that returns mew to the gridview:
dvwUser.ChangeMode(DetailsViewMode.Insert);
I am facing a situation where I have to disable GridView field (in EDIT mode ) conditionally.
Here is the situation,GridView has 5 fields "Product Name" "Small" " Medium" "Large" "XLarge"
Here is the problem, application has section where user activate/deactivate sizes (SMALL,MEDIUM,LARGE,XLARGE). Suppose User activates "SMALL" and "LARGE". Now When the GridView is populted normally, I don't have to disable any fields. But when the user clicks "EDIT" on GridView row, I want "MEDIUM" and "XLARGE" fields to appear as disable.
Here is what I know
1) I will have active sizes in SESSION ... in the above case (SMALL and LARGE)
2 I know I have to catch GridView_RowDataBound and then I have to check for the edit mode for the row.
Then What ?I am using templates for each field

View 4 RepliesI have a grid view with edit and save buttons when I click on edit it is letting me edit it and if I click on save it is lettingme save the data that I have edited.
The thing is after save is done it is showing the data in edit mode i.e <edit item template > mode I am still seeing the textboxes if I refresh the page then I am seeing it normally.
How can I stop the gridview to show edit mode after the save is done?
- I want to put multiple rows of a gridview into edit mode
- I have not found any easy method to accomplish this task. I found a way to programmatically put a gridview into edit mode, but in testing the code below it works for only 1 row at a time :

How do I change these hyperlinks to say something other then Edit and Cancel?

View 3 RepliesI have a gridview and a template column:
<asp:TemplateField HeaderText="Active">
<EditItemTemplate>
<asp:CheckBox ID="chkbxActive" runat="server" Checked ='<%# Bind("Active") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblActive" runat="server" Text='<%# Bind("Active") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
The item "Active" is a bit from the database And for the RowDataBound:
Const HeavyCheckMark As Char = ChrW(&H2714)
For Each row As GridViewRow In gvProductCodes.Rows
If gvProductCodes.EditIndex = -1 Then
' Selects the text from the Label which is inside the GridView control
Dim lblActive As String = CType(row.FindControl("lblActive"), Label).Text
lblActive = lblActive.Replace("True", HeavyCheckMark)
lblActive = lblActive.Replace("False", "")
'Replaces the text in each Label control
CType(row.FindControl("lblActive"), Label).Text = lblActive
Else
Dim chkbx As CheckBox = CType(row.FindControl("chkbxActive"), CheckBox)
End If
The check mark works fine when not in edit mode. But when in edit mode, the row that is being edited works as expected. But the other rows now show True or False. I want them to have the const HeavyCheckMark in it instead.
I have a dynamically built gridview in which every row in editing mode has 2 dropDownLists, i set autoPostBack property of first list to true in order to change the other list values according to the first, but upon postBack, the gridview is not in edit mode any more.
View 7 RepliesI have a webform with two gridviews; a textbox for the invoice number, and a button to kick everything into action. I programmatically handle the select statements in the VB.Net file because I need to iterate through the second gridview's table to perform calculations and then put those results into the first gridview's table. Then I bind them. It works just fine.
The first gridview has one row with the payment information. The second gridview has multiple rows with the items that the payment is handling.Now I need to handle the edit, update and cancel functionality. I tried using a sqlDataSource for edit, update and cancel because it is simple, but it requires a Select statement so I guess that idea is not going to happen. I put a commandField with showeditfield=true, but clicking edit gives an error that rowEdit isn't handled. I have put that sub gvInvoice_RowEditing in there, but being new at this I have no idea what to put into that sub.
I can programmatically create all that functionality in the code behind. Won't it be quicker and easier if I write sub's for Edit, Update and Cancel that tell the gridview what to do - trick it to automatically handle all that? Is there an example available demonstrating how to tell the gridview to go into edit mode and proceed as if it was using a sqlDataSource?As a final note: perhaps it would be simpler if I create a third gridview to handle the job of totaling all the cash and listing each check seperately.Here is my code. It probably isn't the most elegant approach, but it works.

I have a gridview placed on the Panel(Scrollbars set to Both).
If I click on Edit button of the gridview for example Row number 100 then the focus of the page goes to the top of page and I always scroll down to the particular record to make changes.
I have a grid view. When I click edit, the OnRowCommand fires and the row goes into edit state. Label becomes a TextBox. I then attempt to alter this value in some way and click update. This again fires the OnRowCommand event. The problem is, when I attempt to capture the new value, it instead just shows the original value.In my grid view I have:
<asp:TemplateField
HeaderText="Start Name">
<ItemTemplate>
<asp:Label
ID="lblStartName"
runat="server"
Text='<%#Bind("StartName")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox
ID="txtStartName"
runat="server"
Text='<%#Bind("StartName") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
In my code behinde i have
TextBox
textBox = (TextBox)row.Cells[4].FindControl("txtStartName");
For the life of me I can't figure out why I can't put my gridview in edit mode. I am using an ObjectDataSource, maybe that has something to do with it. The problem is that the gridview won't go into edit mode when the edit is pushed. Here is some of my code:
ObjectDataSource:

GridView:

I will troubleshoot my Match class methods after I get the gridview edit mode working.
Is there a way to update a value in a gridview, by pressing a button that shows within the cell? For example, i have a really simple gridview showing supply levels, I havr the following SQL table:
ID = Int
PartNumber = varchar
Quantity = Int
I would like to be able to press a "Plus" or "Minus" button on the gridview next to the Quantity (in stock) value which updates the database and re binds the data to the gridview, but without going into edit mode.
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.

I am working with VWD Express and Visual Basic. take this into consideration if you are willing to answer my question. I do have the following code for a GridView.
<asp:GridView
ID="OpenCloseUDTIGameThreadGridView"
runat="server"
AllowPaging="True"
AutoGenerateColumns="False"
DataKeyNames="AutoNumber"
DataSourceID="OpenCloseUDTIGameThreadSqlDataSource"
CellPadding="4"
ForeColor="#333333"
PageSize="100" >
<Columns>
<asp:TemplateField HeaderText="Picture">
<ItemTemplate>
<asp:ImageButton
ID="ThumbNailImageButton"
runat="server"
Width="75px"
PostBackUrl='<%# string.Concat("~/Classifieds/DetailPage.aspx?AutoNumber=",Convert.ToString(Eval("AutoNumber")),"&FlagForm=NoSubmitted") %>'
ImageUrl='<%# IIF(System.IO.File.Exists(Server.MapPath(string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"))), string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"), "~/UploadedImagesClassifieds/NoPicture.gif")
%>' />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" />
<asp:BoundField DataField="TCategory" HeaderText="Category" ReadOnly="True" SortExpression="TCategory" />
<asp:BoundField DataField="TItemTitle" HeaderText="Item Title" SortExpression="TItemTitle" ReadOnly="True" />
<asp:BoundField DataField="TUDTIThreadActualStatus" HeaderText="Actual Status" SortExpression="TUDTIThreadActualStatus" />
</Columns>
</asp:GridView>
As you can see the second cell in each row is a EditButton, and the only cell that could be updated by users is the last one, DataField = TUDTIThreadActualStatus. I just want to know what could be the easiest way to validate the user entry when the row is in edit mode. Is there anyway to validate the textbox control with a validation control or is better to used code behind. Either way may you explain and drop some code if posible.
Is it possible to set the width of the textbox in edit mode equal to the width of the column before entering edit mode? I basically want to go into edit mode without change the size of the grid and without just setting the textbox width property to a specific number.
