Forms Data Controls :: Clear Fields In Edit Mode Formview?
Mar 2, 2011
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.
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 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.
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.
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 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 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 have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
I have a page where I have a tab container and four tabs. the problem is on the first tab "manage quote request" I have a Gridview with the quote request general informatin listed and have a template field created with a link button to databind to the formview quote details. the porblem comes in when after I click on the select linkbutton. the Formview loads right. Then Whe I try to click on the edit linkbuttin in the form view I have to click it twice to change the mode to edit.
i am getting some errors with my asyncFileUpload. I have a page with <formview><updatePanel><AsyncFileUpload> when it is in ADD mode, the page works fine. Now I put it in EDIT MODE. I open the page and it works fine but as soon as i try to upload an image the nightmare starts. Debuggin I can arrive to these conclusions:
when I open the page for the first time, the sequence is: method load, AdFormView_ItemCreated (empty method), the Bind Process, AdFormView_DataBound.... Everything is ok. I click the button to upload and: AdFormView_ItemCreated, CONTROLSKIN(), Load, DataBound... but at this point controls are not recognized. The FormView has not been created.
How do I clear my formview after a record has been inserted or deleted? At the moment it just sits in the previous state with the same details in the fields, still with the Insert button. Either it would be good to drop the formview altogether (I have a grid view on the same page) or move into the edit mode for the just inserted record.
Also the same with the delete - the formview stays on screen with the deleted record details and the delete button still available - I know it has fired though as my gridview is updated.
A DetailsView in Insert mode has all fields cleared after events such as the following:
1. Clicking New. 2. Clicking Cancel. 3. Clicking Insert (if the default mode is Insert).
I have some fields linked to ViewState and they are populatd at PreRender event handler. I am wondring if there is a single place where all relevant ViewState elements can be cleared instead of doing this in all possible relevant handlers such as ItemCreated, ItemCanceled, ItemInserted, etc.
I have created a FormView whose defaultmode = "insert". When loaded the FormView displays the InsertItemTemplate. At the top of the page is a DropDownList used to select Clients. I have added a list Item to the DropDownList with value = "0" and text= "Select Client" option. So the Page is in Insert Mode. SO FAR EVERYTHING IS AS EXPECTED.
When I select a Client from the DropDownList, the page remains in Insert Mode (Don't understand why? ) Could it be the default Mode setting? So I added the following vb code.
Protected Sub ddlSelectClient_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSelectClient.SelectedIndexChanged
If ddlSelectClient.Text <> "(Select Client)" Then If FormView1.CurrentMode = FormViewMode.Insert Then FormView1.ChangeMode(FormViewMode.Edit) End If End If End Sub
So after an existing Client is selected, the FormView Mode should be changed to EDIT. AND INDEED THE EDIT ITEM TEMPLATE IS DISPLAYED.
Ah but life is not so simple (after all this is a Microsoft Application). So I enter data in some fields and click the [Update] Button.
Then I get the following message:
FormView 'FormView1' must be in edit mode to update a record.
THe FormView displays the Edit Template, the Update and Cancel Buttons are displayed. All this should mean I am in edit mode.
Just call me FrankenSoft !@#$%^^& or is it MicroStein?
Oh by the way I'm using Linq to SQL data sourcess. Should I be? I'm having a lot of problems with the FormView using Linq.
I have a Gridview that handles double clicks. On a double click, the selected row goes into Edit mode, which means in my case that edit controls (textboxes, checkboxes and dropdown lists) become visible, and display controls (labels) become invisible. On Page_Load the values in edit controls get saved. Now my question is this: how can I get out of the edit mode if I don't want to save? Can I e.g. handle Escape key? BTW, I use C#.
Formview1 datasource ID is SQLTest. When I click New on the form and go into insertmode, is there an easy way to auto file textboxID to the value of the NextIDNumber field ( field 9) from SQLTest datasource?
