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

I have gridview that has month as a column. When the user clicks a row's edit button, that row goes into edit mode. I have created a drop-down list for month in edit mode with the values 1-12. Right now, the drop-down list shows 1. I would like it to show the current value for that row. How do I do this? Here's the code for my gridview:

Here's some applicable code from the code behind:

How to disable editing the data in the cells of datagridview in c#?
View 1 RepliesThis is my first post on this forum. I have a Gridview with the following Columns
1. Edit Column
2. User_ID (Read Only)
3. Email (Read Only)
4. Role ( A Dropdownlist with 2 list Items namely "Admin" & "QA Lead")
I have used wizard to populate a "Gridview" and the embedded "Dropdownlist" control in it. This is my reference: [URL] My Problem: The Data populates perfectly in Grid and Dropdownlist. But, when I Press "Edit" button the Dropdownlist goes into edit mode in the form of a "Texbox". (i dont want this) I still want it to be an editable dropdownlist.
I have a dropdown list inside a gridview:

I have a Gridview showing the MemberLastName, MemberFirstName, MemberBirthYear, MemberGender, MemberRelationship.
During Edit mode, I have managed to display a DropDownList for the Relationships.What I am trying to achieve now, is that, based on the Gender of the member I would like to limit the items in the Relationships dropdownlist.
e.g if the Gender is Male, then only display Male Relationships
What is the best way to achieve this scenario?Here is my snippet of code for the event. The code is commented out as it throws an exception.

I have GV with custom edit box. In the GV, I have a button to select the record for editing and another button to navigate to another screen. I was able to disable the button that navigates to the other screen in both normal and edit mode.
Now, I would like to disable all other buttons that remains visible for the other records list to prevent the user from editing other records while in edit mode.
I think my problem is because I am trying to disable a button that is not visible?
In my site, I am using an updatepanel and a timer to refresh gridview.
It may not be a direct link with DD, but I would like to know whether there is a way to stop the timer while the users are in Edit mode.
After the user enters some data in the Grid and if the timer ticks before updating the data, all information is gone.
I 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 i add DropDownList in edit mode of DataGridView by DataSet through code not visible?
As we know that by default Every Column in Edit mode is a TextBox I want to replace this to DropDownList through code.
How do I change these hyperlinks to say something other then Edit and Cancel?
View 4 RepliesI'm trying to programatically populate some dropdownlists inside a formview in EDIT mode, like this below.
[Code]....
I orginally had this running as part of the pagelaod event, but I'm thinking that b/c the page loads first, it doesn't populate the fields in EDIT mode until after the data is saved, and then page is reloaded. Now it knows it's in "Edit" mode. Am I thinking clearly here? Not sure if this is the order of things. So I thought I should just use a formview_modechanged (or similar event) so when the user switches modes, it populates the fields - but I'm not sure which event I should use. I've tried "Modechanging", "modechanged", "prerender", etc, but with no luck. Here's my new code... not sure what's up? Is it simply I've got the wrong formview event? Or am i missing something? Is there an easier/better way to accomplish this?

how to bind drop downlist in gridview edit mode, and BIND THE DROP DOWN LIST WITH FROM THE DATA BASE VALUE, and how to handle dropdownlist values for query update,
one more issue,how to add the ROW from grid view, with button click( i want to place button only in footer )
How can I set a particular row into edit mode in code? Like when the Grid loads up I need the last row to be in Edit mode.
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.
View 3 RepliesI have a webform that contains a few textboxes with required field validators and a gridview. I'm trying to add an edit function to the gridview, but when I go to update the textbox validators fire. Is there someway to trap the edit event and disable the rfvs? Will 'Mark As Answer' for replies leading to a solution.
