Forms Data Controls :: Show Data In RowEditing Mode?
Aug 26, 2010
I have show data in gridview. when search item. And for updating We use Edit button. When I click on edit button it doesn't show data. I have also bind again data. It doesn't show data . The gridview doen't display.
but When I enter search number again then display it.
I have a gridview and detailsview that are connected. When I delete records everything works fine except when I delete the last record in the gridview. I want the detailsview to revert to insert mode when I delete the last row in the gridview. Instead the detailsview shows up blank. I want to show the detailsview in insert mode after last row in grid has been deleted? How can do I this?
i am developed a grid view using tmplate fields. i have done addition and deletion of row using java script and ajax(using web method). now i want to impliment the editing of the grid row using javascript without autopost back Here is the template field i am using.....
I have a Gridview with AutoGenerateColumns= true and AllowSorting=trueBelow is the code snippet I have in RowEditing. This works fine if I dont change the column order in future.Is there a way I can access the headertext and do something like this
If headertext="Start_StateID" Then dim Start_StateID As Integer = TheRowinEditMode.cells(this headercolumns index).text end if
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 am using radiobuttonlist and textbox in the gridview. I need to do operations on radiobuttonlist so that it should reflect on textbox . this is to be done after gridview_rowediting event fires i.e when we can see "update" and "cancel" buttons. I tried like this,
[code]...
here default selected value is "0" given in source.
My problem here is when I am changing the selecteditem, the corresponding action is not done.
I am unable to find any control in row editing event of gridview that i have put in edit template. I have to populate the dropdown control so that in editing the user can select value from the control.
How ever i can access the controls in row updating .But i need it in row editing event.
I've got a gridview that returns student order history which works just fine. It pulls the StudentId from a hidden field on page load. I have a link button that ADDS AN ORDER when clicked. It calls a stored procedure, inserts the record, then rebinds the gridview and displays the new record at the top of the list.
Problem is when I go to EDIT it, i get this error... "The GridView 'GridViewOrderHistory' fired event RowEditing which wasn't handled." But the interesting thing is the error doesn't occur if I close the browser and reload the page and then click on that new record that was created. Obviously I'm missing something in my code when the new order is created. Here are the 2 subs involved in the process.
I am populating the gridview on the basis of listbox selection . However, I am setting the datasource in the click event after listbox entry. When i am trying to update any record in the gridview this error gets thrown because the datasourceid from the aspx page has been removed. Code for reference -
protected void btn_save_Click(object sender, EventArgs e) { ArrayList list = new ArrayList(); foreach (object o in ListBox2.Items) { list.Add(o); } string str2 = null, str, host; string str1 = "SELECT SYSTEMNAME, DATETIME, PDOWNTIME, UDOWNTIME, SYSDOWNMINS, REASON FROM PLANNED_DOWNTIME where "; host = Convert.ToString(list[0]); str2 = " ( SYSTEMNAME like '" + host + "'"; for (int i = 1; i < list.Count; i++) { host = Convert.ToString(list[i]); str2 = str2 + " or SYSTEMNAME LIKE'" + host + "'"; } str = str1 + str2 + " )"; string connectstring = "Data Source=SRCPA035\ovops;Initial Catalog=reporter;Persist Security Info=True;User ID=sa;Password=ril123"; DataTable dt = new DataTable(); SqlConnection connection = new SqlConnection(connectstring); try { connection.Open(); SqlCommand sqlCmd = new SqlCommand(str, connection); SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd); sqlDa.Fill(dt); if (dt.Rows.Count > 0) { GridView1.DataSource = dt; GridView1.DataBind(); } GridView1.DataSource = SqlDataSource1; } catch (System.Data.SqlClient.SqlException ex) { string msg = "Fetch Error:"; msg += ex.Message; throw new Exception(msg); } finally { connection.Close(); } }
gaining mode changing for formview in VB.The problem is that, the current mode im using was ReadOnly, and i want to add some button so thatit could connect to Edit mode in the same formview.Is it necessary to add modechanging and modechanged in the back code?
I have a listbox in the formview. The listbox has selectionmode = multiple. The previous programmer has setup such a way when a user selects multiple items in the listbox, the data are stored with comma delimiter. For example, Listbox have values A, B, C, D, E. If user selected A, C, E and the data are stored in a field as A,B,C. Now the business requirement has changed and the user should be able to edit the data they entered. I want to able to show user which data they selected when they inserted data i.e. In the edit mode, the listbox should have A,C,E as highlighted. How can I do that? I can not use Eval("fieldname") because the listbox can not find the data "A,C,E" in the available listitems.
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?
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#.
When I make a simple change to a style property in a CSS class the change only effects the webform in design mode. It has no effect on the web form when viewed in a browser. Why?
I tried the Hotfix above "Design view does not update HTML" to no avail. Is there a 64 bit version of this hotfix?
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
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.
Even though I searched for a similar posting (and couldn't find it), I am certain that someone must have raised this question in the past.
I am relatively new to the .net world and I am using VS2010/SQL Server 2008. I can't seem to find the problem, but when I click on the "edit" button I get a postback but I get the ItemTemplate again.
