Forms Data Controls :: Change Textarea Or Textbox Multi Mode?
May 9, 2010
when we use standard gridview update field it used textbox as a small size i want to change it to textarea or textbox mutli mode or anything else but my problem is i can't to send this data to parameter even i use object data source.
I have a textbox inside edit template and it is binded with the data. Somehow, textbox data starts from the middle instead at the beginning of the box. I can use textarea where it starts from the starting point but I cant bind the data inside the gridview.
way to change a ListView into Insert Mode when linkbutton is not part of the ListView? Basically I have a button at the top of my page and when the user clicks the button I'd like to put the ListView into Insert Mode. I'm assuming that it's not working currently because the button is NOT part of the listview Layout Template.
<asp:LinkButton ID="lnkMachines" Text="Create New Machines" CommandName="Insert" runat="server" onclick="lnkMachines_Click" /> [code]...
I've got a DatalList control on a page that I intend on using for Editing Items. I've added a button control into the Item Template with CommandName="Edit", and when click the button on the item, the page Posts Back and continues to display the ItemTemplate for that item.
I am trying to handle the detailsview programmatically but I don't know what I am doing wrong. My details view control isn't going into edit mode. My code for my gridview's select button properly loads the data into the detailsview but once the detailsview renders clicking on "Edit" doesn't switch the detailsview contol into edit mode.
This code draws the information from my database and loads the information into the dataview:
This code is in my dvTeamDetails_ItemCommand sub and the beep works:
I'm a complete novice in .NET. I am trying to implement a multi textbox / dropdowns / checkboxes search for a website using vb.net. How do I pass the values of my form fields to my griedview and display the search result on the same page?
I've written a stored procedure and specified it as data source for my gridview and defined parameter source as my CONTROLS (textboxes, checkboxes n dropdowns) on the form. What I want is when a user fills out one or multiple fields on the form, how do I display data in the gridview on the click of SEARCH button? Also is it necessary to write a codebehind for my search button or we can achieve the desired result in some other way?
My gridview can have several hundred records, and therefore users will have to scroll down to view and edit some of them. The problem is when they want to edit a record that they have to scroll down to, when the page enters edit mode it stays at the top of the page, instead of focusing on the current record, how can I change it to scroll to the correct record in edit mode?
I guess I'm not sure exactly how or where to do what I need.
First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.
I've tried using the ModeChanging (and ModeChanged) event: Dim dv As TextBox = CType(DetailsView1.FindControl("txtNew"), TextBox) If (e.NewMode = DetailsViewMode.Insert) Then ....
However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.
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 System.Web.UI.WebControls.TextBox.RaisePostDataChangedEvent() +55 System.Web.UI.WebControls.TextBox.System.Web.UI.IPostBackDataHandler.RaisePostDataChangedEvent() +10 System.Web.UI.Page.RaiseChangedEvents() +165
I have a gridview that I would like to the set the textbox in edit mode to multi line in order to show more of the content of the cell. Does anyone know how to change this property, I have tried (I think) every single one I could find in the Gridview property settings for editstyle, item style, row style etc.
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.
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
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.
I am simply trying to get a querystring value and pass it to a textbox in a formview with the default view set to edit mode.
Protected Sub fv_Detach_Engine_DataBound(ByVal sender As Object, ByVal e As EventArgs) Handles fv_Detach_Engine.DataBound If fv_Detach_Engine.CurrentMode = FormViewMode.Edit Then Dim tbx_IDProfileAccount As TextBox = TryCast(fv_Detach_Engine.FindControl("tbx_IDProfileAccount"), TextBox) If tbx_IDProfileAccount Is Nothing Then tbx_IDProfileAccount.Text = Request.QueryString("IDProfileAccount") End If End If End Sub
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?
