Forms Data Controls :: DataList Won't Change Mode To Edit?
Mar 10, 2010
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 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 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:
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 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#.
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
The item "Active" is a bit from the database And for the RowDataBound:
Const HeavyCheckMark As Char = ChrW(&H2714) For Each row As GridViewRow In gvProductCodes.Rows If gvProductCodes.EditIndex = -1 Then ' Selects the text from the Label which is inside the GridView control Dim lblActive As String = CType(row.FindControl("lblActive"), Label).Text lblActive = lblActive.Replace("True", HeavyCheckMark) lblActive = lblActive.Replace("False", "") 'Replaces the text in each Label control CType(row.FindControl("lblActive"), Label).Text = lblActive Else Dim chkbx As CheckBox = CType(row.FindControl("chkbxActive"), CheckBox) End If
The check mark works fine when not in edit mode. But when in edit mode, the row that is being edited works as expected. But the other rows now show True or False. I want them to have the const HeavyCheckMark in it instead.
I created a sample gridview. However, when I clicked edit mode in one of selected row, it will run away. I need to use the mouse scroll up and down to find that row. As well, once finished the edit (clicked update button), it will run away again. I also need to find the editted row by using the mouse. How do I fix the position? Furthermore, I also want to fix the header. If I scroll down, the header row will be on the top where ever I scroll to.
Student Name: John Exam Grade MidTerm1 A MidTerm2 B
For this, I defined a class 'Student' that has the properties StudentName[String] and Exams [a list of ExamGrade objects which has the Exam and Grade properties]. And I am using nested listviews to display the data. Here is the markup for the ListViews:
And the StudentInfo class looks like this:
And Exam class has just two properties.
Now the issue is that I have to press the Edit button [link button] twicw to get the EditItemTemplate. Even then I would get the blank textboxes. So what should I do to make the EditItemTemplate appear on the first click and the TextBoxes to appear with the existing data?
Edit mode does not run all the times I have a gridview with custom edit (I have my own textboxes placed in the EditItemTemplate for updating). When the user clicks the Edit button, the gridview goes into edit mode with no problem. In RowDataBound handler, I have the following code which checks if the edit mode is in process then an additional function will be called.
The problem is, I noticed that RowState and function are NOT called every time the GridView goes into edit mode but it goes every other line!!! For simplicity, I have blocked the function and put direct code. I have also tried the Edit functionality provided by the GridView, and surprisingly, it is NOT working!! Notice that in both ways, the gridview is displayed in Edit mode and it does display the Update Cancel buttons in my second try. It is working fine in all alternate rows! I hope it is clear.
My gridview was working just fine until I converted the Officer Report collum to a templatefield so I could have a multiline text box. Now when I go into edit mode and press update, it doesn't update. I don't know what I am missing here?
I have a dynamically built gridview in which every row in editing mode has 2 dropDownLists, i set autoPostBack property of first list to true in order to change the other list values according to the first, but upon postBack, the gridview is not in edit mode any more.
I have GV with custom edit box. In the GV, I have a button to select the record for editing and another button to navigate to another screen. I was able to disable the button that navigates to the other screen in both normal and edit mode.
Now, I would like to disable all other buttons that remains visible for the other records list to prevent the user from editing other records while in edit mode.
I think my problem is because I am trying to disable a button that is not visible?
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 have a webform with two gridviews; a textbox for the invoice number, and a button to kick everything into action. I programmatically handle the select statements in the VB.Net file because I need to iterate through the second gridview's table to perform calculations and then put those results into the first gridview's table. Then I bind them. It works just fine.
The first gridview has one row with the payment information. The second gridview has multiple rows with the items that the payment is handling.Now I need to handle the edit, update and cancel functionality. I tried using a sqlDataSource for edit, update and cancel because it is simple, but it requires a Select statement so I guess that idea is not going to happen. I put a commandField with showeditfield=true, but clicking edit gives an error that rowEdit isn't handled. I have put that sub gvInvoice_RowEditing in there, but being new at this I have no idea what to put into that sub.
I can programmatically create all that functionality in the code behind. Won't it be quicker and easier if I write sub's for Edit, Update and Cancel that tell the gridview what to do - trick it to automatically handle all that? Is there an example available demonstrating how to tell the gridview to go into edit mode and proceed as if it was using a sqlDataSource?As a final note: perhaps it would be simpler if I create a third gridview to handle the job of totaling all the cash and listing each check seperately.Here is my code. It probably isn't the most elegant approach, but it works.
