Forms Data Controls :: Populate Textbox In FormView Control In Edit Mode With Querystring?
Sep 9, 2010
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
I am using a textbox and button to get the user input (account number), this will be used as input to a data access class object (SQL) when the button is clicked. This action should populate the Formview control. I have bound the Formview control to the SQLdatasource and configured the SQLdatasource control to the textbox.TEXT property. What am I missing? What do I need to add to button_clicked event to get all this to work? One other thing, the textbox is in a table area separate from the formview control. I have each of the templates inside of the formview control in tables. The input textbox and button are displayed but the formview control is not, all of this is in a master/detail object.
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.
This is what i have using VS and VB: formview that is bound to a sqldatasource. In the formview i set up three panels and the visibilty is controlled by three buttons. I want to be able to click the edit link button and have the panel that is visible in readonly mode be the one visible in editmode
there are 2 pages (SummaryGridviewPage.aspx and FormviewPage.aspx) there are insert, item and update templates in the FormviewPage 1st case - there is no problem to insert new record, select and update action in the FormviewPage
2nd case - However, there is problem when i select a record in GV and direct to FormviewPage for edit this code is added in Formviewpage to open the record at readonly mode, no problem
Private Sub RF_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init If Session("RecordID") <> "" Then ' to check New or Old record SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID") FormViewProject.ChangeMode(FormViewMode.ReadOnly) End If End Sub
however, no record if go further from readonly to edit mode then Code is added to the Edit button
Protected Sub BtnEdit_Click(ByVal sender As Object, ByVal e As EventArgs) FormViewProject.ChangeMode(FormViewMode.Edit) SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID") FormViewProject.DataBind() End Sub
Now edit problem is solved but when go back to the 1st case (new record, and then edit) Now new record can be inserted, and then show it in readonly mode. but then try to go to edit mode, no record show i think BtnEdit_Click code is conflicted with the built-in "Edit" command Could anyone show me some info how formview retrieve specific record in a proper way?
I'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?
I have a combobox that is used as a control for Formview, so when the user selects a name from the combobox the data in formview displays in edit mode. However, some if the data that is displayed in formview needs to be empty. For example if the Date is being pulled in, it needs to be empty or null in edit mode.
I'm having a hard time solving what should (I think) be an easy problem. I have a formview defaulting to Editmode. One of my data fields is a binary image. How can I change the editItem template to allow a user to upload a new image into the binary image field?
The following code successfully displays a record in a FormView and sets the FormView mode to 'Edit' when the user clicks on a LinkButton within a Repeater, however the record is not Updated. If I don't change the .SelectCommand and call .DataBind, I'm able to update the first record that is displayed. Naturally that's a moot point because the idea is to be able to update the record that the user selects in the Repeater.Because of the design of the FormView and Repeater, the record *must* be updated via the FormView. Updating the record via the Repeater is not an option.
In web config file I have add key values specified.
In the formview I have labels on edit , item and insert mode that I want to display all the time by getting those values from web config. I'm able to do that with no problem but when I change the modes between edit to insert or item view, I lose those label values until I hit the "select" twice from the Gridview, those values re-appear. Below is the snippet of the code. What do I need to do to retain the category values all the time?
I have a table in my database called "Profiles". This holds data on Female and Male personal characteristics.On my aspx, I have a formview in edit mode which is binded to an object data source with a GetDataByUserId Select methodwhich retrieves data from the "Profiles" Table via a DAL.The "Profiles" table has some columns which relates to females only and some just males and some are generic to both.See example below
UserId - / of Type GUID GenreId / of Type BOOL. Hip Size (For females) Dress Size ( For Females) ChestSize (For Men ) TrouserSize (For Men) Weight ( For both )
When the User logs in , they go to an update Page which has the Formview in Edit Item Mode and contains drop down Lists whichare binded to the Users Selected Value. The DDL are in turn bound to their related table such as HIP, Dress, Chest, Trouser etc.bjectiveIf a female user logs in I just want to show them the (Hip Size) DDL and DressSizeDDL in the Edit item template of the formview and not the ChestSize DDL or TrouserSize DDL.At present the GetProfileByUserId returns all colums from the tableMy question is how do I do this and just show DDL which are relevant to the Female or Male Only. In some cases the usermay not have selected an item in the previous form so they could also be NULL.Am i on the right path by writing a Select Query that checks to see if the User is Male or Female by checking the Genre column in Profiles first.Do I also need 2 panels, 1 to hide Female DDLS and the other to Hide MaleDDLs subject to logged in user genre.
I created a formview that I am using for data input (DefaultMode=Insert)
One of the objects I have is a text box (see below)
[code]....
When I click submit I get a message that I cannot insert a Null into the field IntershipNumAvailable. This makes sense since I made this field a required field in the database.
How do I get the form to recognize that the user selected item is the one I want to write to the database?
What changes do I need to make here? Do I need to make changes to my parameter list?
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.
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.
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.
I have a drop-down list that is wired up to a datasource from one table to retrieve a Vendor ID and Vendor Name. This ddl is outside a FormView that is wired up to a datasource containing Vendor contracts.
When I choose a Vendor from the ddl, I am able to populate a textbox outside of FormView with the Vendor ID from the ddl. However, what I need to do is populate a textbox within FormView with the Vendor ID. FormView is in Insert Mode by default since my page will be used for Adding Contracts only.
I have an email contact form that I have successfully populated the account users Username and email address into text boxes
I also use a text box and session variables to send parameters to a stored procedure and return a single row result in a form view.
The thing I am having an incredibly hard time figuring out is how to populate a single textbox with the data from any of those fields. or the whole control as a single summary.
Just for starters I am actually an IT Manager and NOT a coder so this is entirely a hack job if there ever was one...
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.
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?
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?
