Web Forms :: Edit Textbox In Gridview Using A DataTable As Its Data Source
Apr 26, 2010
I have a Gridview that is using a DataTable as its data source. I want the user to be able to edit the quantity column in the grid.
I have a TemplateField with a LinkButton2 for my Edit command. I have a TemplateField for my "Quantity" column that has Label for the <ItemTemplate> and a textbox for the <EditItemTemplate>
How do I get the grid to switch from the <ItemTemplate> to the <EditItemTemplate> when the user clicks on the Edit Hyperlink.
The Code:

In my gridview, I have a column for Amount. I want to calculate the amount as soon as user changes the Amount and display calculated Amount in a textfield. What I have done is I have Amount as Templatefield and have set Autopostback = true. In the event handler for textChanged I have function for calculate Amount which will calculate the amount and set the calculated value in a textbox. But I am getting an error message:
[NullReferenceException: Object reference not set to an instance of an object.]
UpdateInvoice.calculateamt() +87
UpdateInvoice.txtAmt_TextChanged(Object sender, EventArgs e) +5
System.Web.UI.WebControls.TextBox.OnTextChanged(EventArgs e) +8739438

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.

This 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.

Is it possible to access textbox text properties from codebehind when gridview is edit mode? for example I can access label's text properties on gridview row databound event.
[Code]....
So I do not like use Text='<%#Eval("ColumnName")%' this method. I want to manage textbox text properties dynamcily codebehind when click the edit button on gridview. When I clik the edit button these code blocks runs
[Code]....
but rowdatabound event fires again and couldn't find label control. It looks for textbox control to bind data but I can not manage this step.

In the example below I have set the control style to 'controlName' I want to use this class to define what my textbox looks like in edit mode. This works ok, so far so good. The Problem In a button event I add the class "validationError" to this textbox if the data is incorrect. When the grid gets rendered I expect to get 'controlName validationError as the class applied to the textbox. Unfortunately, it seems that the declarative statement overrides this and simply ends up as 'controlName' how I can intercept the application of the declarative class so that I get what I desire here?
<asp:BoundField
DataField="Name"
HeaderStyle-CssClass="headerName"
ItemStyle-
CssClass="itemName"
ControlStyle-CssClass="controlName"
HeaderText="Name"
>
</asp:BoundField>

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?

Can someone tell me if there is a technique to make an entire Column within an gridview (for example digits) editable (instaed of a single row) and update this column after changing values by press an Update-button?
A commercial solution is also o.k. with me, but, of course, a method to do it ourselve would be nice.

I have a page with 2 GridViews on it. The top GridView shows all the Bike Riders the bottom GridView shows all the Bike Lockers. I have set up both GridViews to be able to Edit the data. And the top GridView to Select.
When I click the Select buton on the top GridView I programically reset the DataSource for the bottom GridView to show the Locker for the Biker of the top GridView Selected.
So far everything works great. I select a Biker on the Top GridView and the Bottom GridView resets just showing one record for the bike locker.
The problem is that if I then click on the Edit button on the bottom GridView (The Bike Locker GridView) the GridView goes into the Edit Mode but it now shows all the Bike Locker records and the edit record is always the top record of the GrdView.
Here is my code Behind:

I have some template columns that have multiple textboxes in them.
There is one textbox for the Date portion of a datetime field and another textbox for the Time portion of the datetime field.
How do I populate those textboxes after the user clicks on the "Edit" button?
My assumption was I could get the data from the label that was displaying the datetime field data, break it down into Date and Time, and then access the textboxes.text property to fill those.
I can get the data from the label control, but when trying to fill the two textboxes with the data, I get Object Reference Not Set... errors.
Im assuming maybe those textboxes are not setup yet during the RowEditing Event?
