Forms Data Controls :: Populate Dropdownlist In Edit Mode Programatically?
Sep 23, 2010
I'm trying to programatically populate some dropdownlists inside a formview in EDIT mode, like this below.
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 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 gridview that has month as a column. When the user clicks a row's edit button, that row goes into edit mode. I have created a drop-down list for month in edit mode with the values 1-12. Right now, the drop-down list shows 1. I would like it to show the current value for that row. How do I do this? Here's the code for my gridview:
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.
I have a Gridview showing the MemberLastName, MemberFirstName, MemberBirthYear, MemberGender, MemberRelationship.
During Edit mode, I have managed to display a DropDownList for the Relationships.What I am trying to achieve now, is that, based on the Gender of the member I would like to limit the items in the Relationships dropdownlist.
e.g if the Gender is Male, then only display Male Relationships
What is the best way to achieve this scenario?Here is my snippet of code for the event. The code is commented out as it throws an exception.
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 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?
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.
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.
